"Did you kill Li Yuan?" Fang Xuanling asked.

Zhang Xuan shook his head, "Li Yuan was deeply poisoned and fell into a severe coma. It is difficult to wake up again."

As he said that, he handed the eagle letter to the two of them. They looked at it together. Fang Xuanling smiled and said, "They can think of this method, but Li Shenfu is indeed a lustful person, and this plan should be effective."

Du Ruhui pondered for a moment and said, "The letter said that Li Yuanji will be the regent and will not dare to ascend the throne for the time being. It mainly depends on Li Shentong's attitude. Li Shentong is a versatile person and will not express his opinion easily. If Li Shimin had no choice, then Li Shentong would definitely support Li Yuanji. As long as Li Shentong's army supports, Li Yuanji will definitely ascend the throne. This is the purpose of his coup."

Fang Xuanling also said: "Du Changshi is right. Only when Li Yuanji ascends the throne forcibly can the foundation of the Tang Dynasty be completely destroyed. We must create this condition for him and preventing Li Shimin's army from entering Guanzhong is the top priority."

Zhang Xuan walked to the wall and opened a curtain, revealing the large Guanzhong map on the wall. Fang Xuanling stepped forward and introduced: "There are basically three roads to enter Guanzhong from Anding County. One is to go west and bypass Longshan and go south to Dasan Pass. This road is not too far away, but more importantly, Dasan Pass has fallen. Li Shimin will not choose this road. The second road is to directly enter Jingzhao County along the Jingshui River. Taking this road is the greatest possibility and the closest road. The third road is to pass through Beidi County, enter Shangjun, and go to Guanzhong on Luojie Road. This road is also possible. If we can find a point that just blocks the second and third roads, then Li Shimin's army will not be able to enter Guanzhong."

Zhang Xuan's eyes fell on a small army city. This small army city is called Changwu City. It is located north of Qianshuiyuan, at the junction of Beidi County and Anding County, which is exactly the only way to pass the second and third roads.

Zhang Xuan pointed to Changwu City and asked, "Where is our closest army to Changwu City?"

Du Ruhui thought for a while and said, "There is a scout cavalry near Maling County in Honghua County, with about a thousand people, two hundred and fifty miles away from Changwu City."

"Can you notify this army?"

Du Ruhui nodded, "There is an eagle letter dot over there."

"Send a letter immediately and say my order to kill them and capture Changwu City as quickly as possible. As long as they keep it for a day, I will give you a great reward."

"But it doesn't make sense to just hold on for a day!"

Fang Xuanling said worriedly: "Unless there is strong support."

"I know!"

Zhang Xuan asked Du Ruhui again, "How long does it take to send an eagle letter to Yan'an County now?"

"It's still the fourth update now, and it's probably delivered this morning."

"Then let Luo Shixin notify him immediately and ask him to lead 20,000 troops to quickly support Changwu City. He must arrive before dark tomorrow."

Fushi County, Yan'an County has assembled an army of about 50,000 people, commanded by General Luo Shixin. Fushi County is about 500 miles away from Changwu City. In such a short time, the infantry will definitely not be able to arrive at Changwu City, but the cavalry is enough. The army has to run 500 miles, and basically cannot stop on the road, and the marching intensity is very high.

But no matter how strong the march is, it must be implemented. Du Ruhui agreed. He also suggested: "Weichen suggested that Li Jing's army strengthen the attack, which can effectively restrain Li Shimin's army."

"Go together!"

Du Ruhui hurried away, and Fang Xuanling asked, "The time for Your Majesty to personally command the army has arrived. When will you set out?"

Zhang Xuan thought for a while and said, "I will explain to the court officials today and I will set off early tomorrow morning!"

Among the three related parties, Li Shimin was the last to know that Li Yuanji launched a palace coup.

The reason is very simple. Tiance Mansion was blocked by Xuanwu Jingwei, and Li Shimin's intelligence point in Chang'an was cleaned by Li Yuanji. He suffered heavy losses and could not use carrier pigeons or engravings to convey messages. In the end, Liu Wenjing secretly sent his family to Anding County to deliver the message.

When Li Shimin received the news, it was the next night. When he learned that his brother and his family were killed, Li Shimin cried bitterly. He ordered the whole army to mourn for his brother who died unfortunately. At the same time, Li Shimin began to assemble the army and prepare to lead a 50,000 army to kill Chang'an and attack the traitors in Chang'an.

The chief secretary Changsun Wuji was shocked when he heard the news and hurried to the big tent to persuade Li Shimin. At this time, Zhang Gongjin had already tried hard to persuade Li Shimin in the big tent.

Li Shimin had a gloomy face and kept looking at Chang'an City on the sand table without saying a word. It was just an excuse to avenge the elder brother Jiancheng. In fact, Li Shimin learned from his third brother Li Xuanba that his father was seriously ill. He also felt that his father was sick strangely. This was very likely a sign that his fourth brother was about to launch a palace coup.

Of course, Li Shimin would not stop him. On the contrary, as long as his brother launched a palace coup, he would have an excuse to send troops to Chang'an. He needed to use his fourth brother Yuanji to clear various obstacles on the road to ascending the throne for himself.

Now that the fourth brother kills his brother and imprisons his father, the court and the country are in full swing, who will support him ascend to the throne? As long as you sweep away the evil spirits and turn the bright world of the court, the throne will be yours.

But Zhang Gongjin firmly opposed Li Shimin leading the army back to Chang'an.

"Your Highness, 150,000 enemy troops are peeping at Longyou. If your highness's army retreats to Guanzhong, not only will Longyou be lost, but even the Beidi County, Shangjun and Honghua County will not be able to be saved. We are only left with Guanzhong and Hanzhong, and the Tang Dynasty is in danger! Please think twice."

But Li Shimin was still unmoved.

At this time, the personal guard reported at the door of the tent: "The Chief is back."

Li Shimin nodded, "Please come in!"

After a moment, Changsun Wuji quickly walked into the tent and bowed and said, "I am reporting to Your Highness!"

"What's the situation in Xiaoguan?" Li Shimin asked.

"Report to your Highness, Xiaoguan's situation is not very good. We have insufficient defense forces, but the Zhou army is still increasing. Once their offensive line is lengthened and they no longer attack from the front, Xiaoguan may not be able to save it."

Li Shimin didn't say anything. In fact, he knew the situation of Xiaoguan very well. If he wanted to defend Xiaoguan, he would have to use at least eight thousand troops, but he only sent 4,000 troops that Wu Yunzhao, and the number of troops was indeed insufficient.

"Your Highness, if you add another 5,000 troops, Xiaoguan's defense will be stabilized." Changsun Wuji suggested.

Li Shimin sighed and handed the letter sent by Liu Wenjing to Changsun Wuji, "You can read this letter first."

Changsun Wuji took it and looked at it, and he seemed very shocked. Although he had received some news in advance, he did not expect that Li Yuanji would actually kill the prince Jiancheng family and imprison his seriously ill father.

After reading the letter, Changsun Wuji said, "Does Your Highness want to go back to compete for the throne?"

Li Shimin nodded, "If I don't go back, the country of the Tang Dynasty will be completely over, and even the roots will be destroyed in Yuanji's hands. This is something Zhang Xuan is looking forward to. This is also the reason why the war has been in a year. I cannot allow the dynasty established by my father to end in such a short time."

"What should I do with Longyou?" Changsun Wuji asked incisively.

"Retake it back later!"

At this time, Zhang Gongjin, who had been thinking, said: "Your Highness, you have a plan to achieve both goals. It depends on whether your Highness can adopt it."

Li Shimin and Changsun Wuji both looked at him, and Zhang Gongjin said, "Your Highness can write two letters, one letter to Li Shentong, and do not ask him to be loyal to His Highness, but please be sure to remain neutral, it is best to remain calm and observe the changes in the situation. Li Shentong is loyal to the emperor, not Li Yuanji, and this request is not excessive. I believe he will accept it. The second letter was written to Li Xiaogong, and he asked him to lead 20,000 Hanzhong troops to the north immediately, and then Your Highness sent 10,000 troops, a total of 30,000 troops. I believe that it will be able to quell the Chang'an Rebellion."

"Good solution!"

Changsun Wuji fisted and palmed, and praised: "This is the best compromise. Although Chang'an has 40,000 troops, Li Yuanji can really control only 15,000 Xuanwu Jingwei. As long as His Highness can hold the banner of righteousness and King Zhao assists, I believe that the Imperial Guard will at least half of the rebellion. Even if the Hanzhong army cannot reach it for a while, we can still quell the Chang'an Rebellion."

Li Shimin walked slowly with his hands behind his back. He also felt that this plan was feasible. He knew the second uncle of Shentong. This person was very slick and never stood in a stance easily. It was exactly what he wanted to keep him neutral. Xiaogong had a good relationship with him. Although he was loyal to his elder brother, he was killed. As long as he raised the banner of revenge for his elder brother, Xiaogong would definitely send troops.

Thinking of this, Li Shimin nodded, "The Hanzhong army cannot be fully dispatched, and half of it must be left to defend Hanzhong. It is enough to let Xiaogong lead 10,000 troops north and head north. I will lead 15,000 cavalry into Guanzhong, and attack from north and south, and Yuanji will undoubtedly be defeated."

"Does Your Highness have to go there in person?"

"certainly!"

Li Shimin smiled at Zhang Gongjin and Changsun Wuji and said, "My third brother and I lead the army south, and Longyou will be handed over to you. How to deploy troops to defend, you two negotiated and decided that I will quell the Chang'an Rebellion and will return as soon as possible."

"Please rest assured that we will definitely defend Longyou."

Li Shimin immediately wrote two eagle letters, one sent to Hanzhong and the other to Yongxian. He ordered his brother, King Zhao Li Xuanba, to lead 5,000 troops to leave first, and he himself quickly set off after arranging military affairs.
