When Xun Yu rushed to the government lobby where Cao Ang was, Cao Pi was indeed in the hall and was discussing something with Cao Ang and Sima Yi. Seeing Xun Yu in, the Cao brothers hurriedly stopped talking. Cao Pi saluted Xun Yu respectfully. Cao Ang hurriedly ordered Sima Yi to arrange seats for Xun Yu himself. When asked about Xun Yu's purpose, Xun Yu raised the official document in his hand and said with a smile: "A few people who were caught in the city who brewed wine privately should be dealt with according to the rules. Chang'an Order found that these people were just first offenders, and brewing wine privately was also for the purpose of sacrifice, not for huge profits, and requested a reduction in sentence for them. Yu was undecided and came to ask the lord to make an announcement. He did not want to catch up with the second son here too."

After reading the official documents brought by Xun Yu, the kind-hearted Cao Ang quickly said: "Since these people did not make wine in the disaster year for profit, but only to sacrifice their ancestors, then let's be lenient. Don't impose corporal punishment, and it's enough to punish hard labor."

"The lord is really a person who loves the people, Yu understands." Xun Yu, who had known that Cao Ang would definitely be lenient to deal with it, bowed down, and then asked casually: "Lord, the second son is here. Could it be that Jiang Gan found new evidence in that matter?"

"No." Cao Ang shook his head and said truthfully: "When my second brother heard that Liu Bei's army was about to arrive in Chang'an, he reminded me to be careful of Liu Bei and not repeat the mistakes of Zhang Lu, Tao Qian and others, but he could not show too much hostility to Liu Bei, which made the hearts of allies and mistakenly formed an alliance to fight against Tao."

"Oh, the second young master came for this matter?" Xun Yu looked surprised and turned to Cao Pi and asked, "Second Young Master, in your opinion, how should our army deal with Liu Bei's team?"

"Returning to Uncle Xun, my nephew thought he should treat him with courtesy, loose on the outside and tight on the inside, so he was solemnly welcomed Liu Xuande and his party, but he must not let him enter the city to garrison." Cao Pi said respectfully: "Now our army can no longer leave Liu Xuande's assistance, so he must be treated with enough respect to him so that he can know the gratitude and respect of our army to him. However, for the sake of caution, our army must not let his army enter the city. He must let his army be stationed outside the city and sent to the front line of Tongguan as soon as possible to avoid any change."

"What the second young master said is very true, and Yu also thinks it should be like this." Xun Yu nodded and asked curiously: "How will the second young master treat Liu Xuande?"

"I originally wanted to invite my brother out of the city to welcome Duke Xuande, but it is inevitable that this will be dangerous. Moreover, my brother is busy with official duties and cannot leave the city for a long time." Cao Pi's tone of reply was even more respectful, "So my nephew wanted to volunteer to bring rewards to the army, representing my brother out of the city to welcome Duke Xuande. When Duke Xuande's army arrives in the suburbs of Chang'an, the brother will lead the officials out of the city to welcome Duke Xuande ten miles. This not only reflects the respect our army for Duke Xuande, but also allows the brother not to leave Chang'an and kill two birds with one stone."

"Oh, what do you think of the lord?" Xun Yu turned to Cao Ang without hesitation and asked.

"Uncle, my nephew has agreed to ask my second brother for a hard time." Cao Ang replied: "Although Liu Xuande was untrustworthy, he led his army eastward in Chen Cang, but our army had to rely on his military rations to help him, so my nephew felt that he should be temporarily tolerant of Liu Xuande and talk about other things after he was repelled Tao Ying. I wonder what my uncle thought about this?"

Xun Yu was very happy and replied after a moment of calculation: "It's great. Yu suggested that Sima Yi go together. Previously, the old lord ordered Sima Zhongda to assist the lord to negotiate with Liu Xuande and get familiar with Duke Xuande's team. It was just right for him to assist the second lord to welcome Duke Xuande."

After hearing Xun Yu's words, Cao Ang didn't think too much and immediately nodded in agreement. Sima Yi's eyes moved and glanced at Xun Yu and Cao Pi. He was a little confused. Cao Pi, who was guilty, had a heartbroken and said to himself: "Why did Xun Yu recommend Sima Yi to meet me with me to welcome Duke Xuande? Is it intentional or unintentional? Did Uncle Xun notice something? No, it seems that I must be more careful in my actions in the future."

In view of the rapid march of the Emperor Liu, in order to prepare in advance, Cao Pi and Sima Yi led a team of Cao army soldiers out of the city west on the same day, carrying a batch of precious gifts and pigs and sheep wine to a hundred miles away to welcome Liu Huangs reinforcements. When setting off, Cao Ang, Xun Yu and others personally sent Cao Pi's team out of the Chang'an city gate. At the gate, Xun Yu also held Sima Yi's hand and told: "Zhongda, the second young master is taking on important responsibilities for the first time. You must help him more and always follow his side. Be cared about everything, don't make any mistakes."

As he said that, Xun Yu also pinched Sima Yi's hand hard. Sima Yi heard Xun Yu's implicit voice and nodded in his heart. He couldn't help but feel suspicious and said in his heart: "Always follow his side and care about everything? This is clearly to me secretly monitor the second young master. What happened? Ah, is it?!"

Thinking of this, Sima Yi quietly smiled and nodded and said, "Mr. Wenruo, please rest assured, Yi understands."

On the same day, there was a news from Tongguan that said that Zhong Yao's team had already retreated to Tongguan City with Zhang He's troops, and reported that less than 800 people from Zhong Yao's 4,000 defenders had withdrawn from Tongguan. Zhang He was also chased by Zhao Yun's team of Xuzhou's army when he was receiving Zhong Yao. Fortunately, Zhang He's team discovered the strange troops of Xuzhou army who were trying to take a small path and encircled around him in time. They divided their troops to block the Xuzhou army's sneak attack team at a dangerous place. After losing more than 500 soldiers, they successfully retreated to Tongguan. Zhao Yun's team, who could not cut off the way back Cao's army, only chased to the west of Huxian and temporarily stationed in front of him. He did not have the momentum to kill the city of Tongguan. It was probably because he wanted to wait until the main force arrived before joining the troops west.

There was not much time left for the Cao army. When the Xuzhou army was only in Tongguan for several days, Cao Ang had to send someone to inform Cao Pi and Sima Yi of this matter, asking Cao Pi and Sima Yi to lead the Emperor's army to Chang'an as soon as possible so as to fight against Tao. Fortunately, the Emperor's army came very fast this time and always maintained the speed of marching 80 miles. So on the afternoon of the next day, the etiquette team led by Cao Pi and Sima Yi welcomed the Emperor's army in the Huaili area west of Chang'an, and met with the Emperor's army who personally led the army to rescue in the evening of the same day.

When I met Emperor Liu amid the rituals and music of playing and playing, Cao Pi and Sima Yi were naturally unlucky to express their gratitude to Emperor Liu on behalf of Cao Ang, saying that he would have arrived in Chang'an early, but because of the sudden outbreak of mountain torrents, the food route was cut off, which made the army unable to arrive on time. He apologized to Cao Pi and Sima Yi, and then introduced Pang Tong, Zhang Fei, Wang Ping and others to Cao Pi, and Sima Yi, and then said a lot of nonsense. Finally, he joined hands to enter the tent set up by the Cao army and held a grand banquet on the land of Guanzhong where the starving troops were everywhere.

During the banquet, Cao Pi reported the military situation in Tongguan to Uncle Liu and asked Uncle Liu to arrive in Chang'an as soon as possible to join forces with the Cao army. Uncle Liu immediately ordered the entire army to speed up the march again and must arrive at Chang'an City a hundred miles away before the next day. Cao Pi and Sima Yi were overjoyed and hurriedly thanked Uncle Liu and parted with Uncle Liu and others.

The banquet ended at the second update, but the affairs of Cao Pi and Sima Yi had just begun. At the second update, Sima Yi, who was sleeping in the same tent, was already asleep. Cao Pi took his hands and feet and left the tent, and then touched Liu Huangshu's central army tent overnight for a visit. After being led into the tent by Liu Huangshu's guards, Cao Pi was surprised to find that Liu Huangshu and Pang Tong were actually in the tent. Cao Pi quickly saluted and said with a smile: "I don't want Military Advisor Pang to sleep yet. I'm so sorry to disturb him late at night."

"The second young master winked at the table several times. How dare Tong sleep?" Pang Tong smiled and asked again: "What? The second young master, Sima Yi, the eldest young master's confidant, is here to monitor you?"

"Maybe, it's not confirmed yet." Cao Pi replied truthfully: "It was Xun Wenruo who suggested that his brother insert Sima Yi into Pi's body. Pi was worried that Xun Wenruo had discovered something, but he didn't know that there was a flaw in it, so he had to act carefully."

"Young Master Pi is cautious." Uncle Liu nodded and asked again: "Young Master Pi, you volunteered to welcome our army instead of Brother Ling, and visited us late at night. Could it be that there is something urgent?"

"I don't hide it from Duke Xuande, Pi came for a plan." Cao Pi confessed, first introducing the general situation of the constant conflict between Cao Ang and the old ministers of the Cao army, and then talking about the intensification of the conflict between the Xuzhou army and the old ministers of the Cao army. Finally, Cao Ang bowed to the Emperor Liu and Pang Tong and said: "Uncle, Duke of Shiyuan, Pi knew that his brother wanted to forget his father's revenge and led the crowd to surrender Tao. He also knew that the old ministers of our army were extremely dissatisfied with his brother's hidden intention to surrender, and had already developed a desire to abolish. In order to prevent the foundation left by his father from being destroyed in the hands of his brother, Pi decided to secretly promote the destruction and establishment, but he didn't know how to start. Wan Wang Uncle and Military Commander Pang would give him advice and help Pi with his help. He said that he would fulfill his long-cherished wish and Pi would definitely repay him."

Hearing the news of the intensification of internal conflicts among Cao's army, the unparalleled and righteous Uncle Liu was secretly happy, but his face remained silent, and turned to Pang Tong and said, "Military advisor, we are waiting for a long time to rescue Cao Ang. I don't expect that Mr. Cao Ang is going to surrender to Tao. It's a big deal. Mr. Pi is so sincere and has repeatedly secretly helped our army. If the military advisor has a clever plan, he might as well offer Mr. Pi."

Pang Tong blinked his green bean's little eyes and quickly said, "This is not difficult, I just don't know when Mr. Pi wants to act? Is it before or after the pottery?"

"I don't have time to do it with me, I can only be before I break the pottery." Cao Pi answered quickly: "Pi thought carefully and felt that if he took action after breaking the pottery, his brother would have the merit of retiring the pottery and his reputation would have increased greatly, and the conflict with the old ministers of our army would be alleviated. Success may be too small. Only by acting before breaking the pottery can you be sure to succeed."

"Young Master Pi is right." Liu Huangshu agreed, "Since Young Master Ang secretly has the intention to surrender Tao, then Young Master Pi can only seize the throne before destroying Tao. Otherwise, if Young Master Ang suddenly orders to surrender Tao, then the plan to fight against Tao will be a major event. After the action, as long as Young Master Pi can support the old man of Cao's army, there will be no problem with Cao Ren, Zhang Liao and Zhang He, the elders of Cao's army, and there will be no problem with him. He will only follow everyone to support Young Master Pi to succeed the throne."

"Okay, since Mr. Pi has decided, and the lord also thinks it is best to do it as soon as possible. Then let's do it in three days." Pang Tong smiled and said, "Our army arrived in Chang'an in the evening of the Ming Dynasty, and then rested outside Chang'an City for two days, and made all preparations. Three days later, we went east to Tongguan to reinforce. We started to take action when we set off, and joined hands with the old ministers of the Cao army to help Mr. Pi inherit the position of Mengde Gong."

"Do it happen in three days? How do you do it?" Cao Pi asked happily.

"Prince Pi, I heard that the former noble army escorted Jiang Gan, the envoy of the pottery thief, to return to Chang'an, but was deceived by someone with a fake Cao Ang warrant. The whereabouts are still unknown." Pang Tong did not answer and asked back, and said with a smile: "If Tong expected it, the imitation and vivid fake warrant should have been made by Prince Pi, right?"

"This..." Cao Pi looked a little embarrassed. After hesitating for a long time, he finally nodded and admitted that it was his own actions.

"Very good." Pang Tong nodded with satisfaction and said quickly: "Please pick up the pen immediately, use Young Master Ang's handwriting and tone to write a letter to the general Cao Ren, crying to Cao Ren about Xun Yu, Cao Hong and others' offenses for tyranny, and begging Cao Ren to uphold justice for him, and hinting that he had the intention of killing Xun Yu, Cao Hong and others."

"A clever plan, why didn't I expect to use the autocratic power of Xun Yu, Cao Hong and others?" Cao Pi was overjoyed and quickly asked for a silk pen to make a book immediately. Then he asked worriedly: "Duke Xuande, Military Advisor Pang, how did this letter be delivered to Xun Wenruo? Pi seemed not suitable to come forward?"

"Don't worry, I won't work hard for Mr. Pi to come forward to deliver the letter." Pang Tong replied with a smile: "Mr. Pi, your third brother Cao Zhi seems to be very concerned about military and political affairs?"

Cao Pi laughed loudly and asked about other steps of the plan. Pang Tong refused to answer, but he just urged Cao Pi to write a letter as soon as possible. Cao Pi had to beg for others and had to be at the mercy of others. He quickly prepared the letter as required and submitted it to the emperor Liu and Pang Tong. After careful reading, Pang Tong was very satisfied and smiled and said, "Young Master Pi is indeed a good literary talent, with reason and evidence, especially the sentence "Hateful to the sky thunder and not killing the thieves of Yu Hong" is just right, which is admirable."

After laughing, Pang Tong ordered again: "Come here, change a brush for Mr. Pi, re-grind the ink, and ask Mr. Pi to make another book."

"Why do you need to change the brush? Change the ink?" Cao Pi asked in confusion.

"Of course, we must be careful that Xun Yu and others will see that the two books in the past and after are all from the same brush and the same inkstone. Young Master Pi, don't underestimate these old foxes. Any clues may make your previous efforts waste." Pang Tong explained with a smile, and then said: "Young Master Pi, use Young Master Ang's handwriting to write a letter to my lord, which is also crying and counting the crimes of Xun Yu, Cao Ang and others for the tyranny of power. Then I beg my lord to help him when the army set off to Tongguan and take Xun Yu, Cao Ang and others down and punish me!"

"Ah!" Cao Pi was startled and asked quickly: "Then how can Xun Yu and others know about this letter?"

"Young Master Pi doesn't have to worry about this. Tong has his own way." Pang Tong refused to answer and said with a smile: "Young Master Pi, don't be stunned, please write it. Remember, this letter must indicate the time. Today is August 28th, and you will arrive in Chang'an tomorrow. Then take a rest for two days. The signature will be written on the first night of the September 20th!"

Almost forced Cao Pi to write these two letters, Pang Tong cooperated with Uncle Liu to say many good words to Cao Pi. He almost patted his chest and promised to help Cao Pi to take Cao Ang's position and replace him. Then he sent Cao Pi back, who was confused. It was not until Cao Pi left that Uncle Liu, who was also in the fog of clouds and mountains, asked Pang Tong: "Military advisor, what are you planning to do? Since you asked Mr. Pi to write these two letters, why didn't you tell him the specific action plan? How did he cooperate with our army?"

"Lord, there is no need to let him know." Pang Tong threw away the two letters in his hand and said with a smile: "With these two letters in hand, Mr. Pi will have no use value. Mr. Pi is already twenty years old and is quite scheming. Why do you need him to replace Cao Ang? Isn't it better to let your future son-in-law, the fifteen-year-old Cao Zhi replace Cao Ang?"

Uncle Liu smiled and said, "The military advisor really knows my heart. By the way, what should Sima Yi do? Cao Ang sent him to greet our army with Cao Pi, but it was a great opportunity to test and bribe him. What would the military advisor do?"

"Let's talk about it tomorrow." Pang Tong replied: "Whether Sima Yi really surrendered to the lord, this remains to be verified, so we cannot take him lightly now, but it doesn't matter. Whether Sima Yi's real surrender or deceitful surrender is no longer important in Tong's plan and cannot affect the overall situation. For Tong, Sima Yi's only function is to disrupt the judgment of Cao Ang, Xun Yu and others, so that Cao Ang and Xun Yu cannot judge our true intentions and time to take action."

Uncle Liu nodded and smiled and said, "The military advisor is indeed brilliant. Although Sima Yi was very respectful and intimate to me when he was welcoming our army, I could see that the child's eyes were calm and calm. Among the people I saw, only Tao Yingji and him made me unable to judge what they were thinking and what they were saying. Children like this must be careful."

……………………

The night passed quickly and the sky finally became slightly bright. When the soldiers of the Imperial Uncle Army stood up one after another to set off again, four hundred and seventy kilometers east of the east, a shocking sound of a gong sounded on the heavily guarded Tongguan city wall. The screams of Xuzhou army coming one after another, shocking the mountains and valleys responded. Cao Ren, the general guarding the gate of Cao army, who lived directly in the gate building, also jumped up from the gate building and rushed out of the gate building and looked eastward.

In the dawn, a Xuzhou cavalry with only more than ten people appeared on the narrow road east of Tongguan, standing on the horse and stepping up, looking up at the Tongguan city tower two hundred steps away. The mountain wind blew their flags and blew them. The rising sun shone the golden sunlight on their armor and swords and guns, reflecting a dazzling light, as dazzling as the gods descended to earth.

"Enough!" Cao Ren yelled at the panicked defender with a dark face, "It's just a scout of the Taoist thief. What's the terrible thing about it? What's the matter like when you panic like this? Stop ringing the gong, don't scream, increase the enemy's ambition, and destroy our majesty!"

The panic was finally forcibly killed by Cao Ren, but every Cao army guard still looked nervous, because the Cao army soldiers knew very well that the decisive battle in Tongguan, which was related to the life and death of the Cao army, was about to begin, and the main force of Xuzhou, who was unparalleled in the world, was coming. Every Cao army soldier may die, and every Cao army soldier will struggle to survive in swords and fire. No one can know who can survive to the end.

The Cao army counselor who assisted Cao Ren to guard the pass, Man Chong walked up to the wall with dark circles and walked to Cao Ren. After looking at more than ten Xuzhou soldiers outside the pass, Man Chong asked in a hoarse voice: "Do you report to the eldest son immediately?"

"No hurry, wait until you find out the situation of the enemy." Cao Ren shook his head and said with a gloomy face: "Besides, what's the use of reporting the eldest son? Can he send reinforcements to us? Maybe he will come to Tongguan in person to command troops to defend the enemy, and that's the matter difficult."

Man Chong, who had already learned about the situation in Chang'an from the letters of Xun Yu and others, nodded, and did not want Cao Ang to come to Tongguan to cause trouble, so he said, "Send someone out of the way to reconnaissance the enemy's situation first, and then send the news to Xun Wenruo and ask Xun Wenruo to pass it to the eldest son, so that Mr. Wenruo and the others can prepare first."

Cao Ren also nodded. Just as he was about to order the scout to be sent to reconnaissance the enemy, he suddenly remembered a major event and hurriedly said to Man Chong: "Boning, you can arrange the matter of sending scouts to the customs and reconnaissance. Here we will be temporarily handed over to you. I have a major event to do."

As he said that, Cao Ren hurriedly walked away. Man Chong asked, "General Zixiao, what's the matter so anxious?"

"When the old lord was about to leave Tongguan," Cao Ren replied in a verbal manner: "I once gave me a sealed wooden box and ordered me to open it when the pottery bandits were at the end of the pass, and then follow the orders in the wooden box. Now the pottery bandits' troops have arrived, so I have to open the wooden box."

"There is this?" Man Chong was extremely surprised. At the same time, Man Chong was full of doubts and said to himself: "No? The old lord went out of Tongguan to fight the pottery thieves. How could he keep a wooden box first and order Zixiao to open it when the pottery thieves were in Tongguan? Why didn't the lord think about it at that time? Even if he was unfavorable in Hanguguan, he should return to Tongguan first? Ah!"
