Xin Liao'er didn't know Luo Cheng. In a rage, he just wanted to smash the person blocking the way with one stick. Xin Liao'er roared and hit Luo Cheng hard. Luo Cheng's silver spear, which seemed to weigh only thirty pounds, was extremely despised by Xin Liao'er, who only advocated power. He didn't take the other party's spear seriously at all, and smashed the mace in his hand at the other party's sky spirit cover with a sharp sharpness.

At this moment, his whole body suddenly became soft, the strength in his hand disappeared, and the mace fell from his hand. Xin Liaoer slowly lowered his head and looked at the spear in disbelief. He didn't see the other party taking action at all, but the other party's spear had pierced his throat.

Luo Cheng sneered, rolled Xin Liao'er off the horse, shot him one after another, and ended his life.

At this time, a thousand cavalry had already entered Canglong Fort, hundreds of cavalry entered the barracks, and nearly two thousand soldiers who had just woken up from their sleep were scared and fled in disarray. However, the gate had been blocked by the Sui army, and the soldiers were desperate and kneeled down and surrendered.

As the sky gradually became bright, tens of thousands of Sui troops arrived at Canglong Fort, and teams of captured soldiers were escorted from the mountain. When Zhang Xuan learned that the Sui army did not hurt, he took the Canglong Fort. He praised it in his heart and laughed at Duan Decao: "General Duan's plan is indeed brilliant. I wonder if we can use this strategy to deceive back to Le County again?"

Duan Decao shook his head and said, "The reason why Beizhi was able to use this strategy in Canglong Castle is because Beizhi understood that Xin Liaoer was fond of horses and was rude and unwise. He would definitely pick a few good horses from the Dangxiang people's war horses, so the strategy was successful. However, Liang Shi was insidious and cunning, and he would not trust Dangxiang people. Moreover, he would definitely use Eagle Letter to contact between Canglong Castle and Huile County. At this time, he should know that Canglong Castle was lost."

"Then what advice do you have for attacking Huile County?"

"Master General, when Bei Zhi led his army to leave Lingwu County, there were only 6,000 people left in Liangshidu. No one in Lingwu County was willing to work hard for him anymore. If his army recovered to tens of thousands in just two months, then these soldiers must have been forced to be recruited into the army. Needless to say, the key is that they will not be willing to work hard for Liangshidu. Without powerful combat soldiers, no matter how tall and strong the county town is built, it is useless. As long as our army captures a gap, the entire army of Liangshidu will collapse, so Bei Zhidu recommends a strong attack."

At this time, the Sui army soldiers brought a group of craftsmen, about fifty people, and a general came forward to report to Zhang Xuan, "Report to the Grand Marshal, these are all craftsmen who built Canglong Castle, and they were also building the Return City!"

A group of craftsmen saw the chief general of the Sui army and knelt down and begged for mercy.

Zhang Xuan smiled and said that it was better to come early than to come by chance. He just needed to understand the situation in the county town, so he caught the craftsmen who built the county town. He ordered the soldiers and said, "Take them with you, don't abuse them, I will use them!"

The Sui army continued to travel westward. In the afternoon, they were only ten miles away from Huile County. Zhang Xuan ordered camping, and tents began to appear in the endless wilderness.

At this moment, a scout rushed over and reported: "Report to the Grand Marshal, General Li's team is here too!"

Zhang Xuan also saw an army in the north from afar, which was the banner of the Sui army. This was the 20,000 troops led by Li Jing arrived. Zhang Xuan was overjoyed and immediately ordered: "Let General Li come to see me!"

Soon, a team of cavalry surrounded the commander Li Jing, the chief general of the North Road, and rushed to the front. Li Jing clasped his fists and said, "I am not good at the commander-in-chief!"

"No need to be too polite!"

Zhang Xuan smiled and said, "When did the general arrive in Huile County?"

"Report to the Grand Marshal, Bei Zhi arrived in Xuanwu Town in the north the night before yesterday, and was waiting for the Grand Marshal's army to arrive there."

Zhang Xuan nodded and asked again: "Is there any defenders in Xuanwu Town?"

"There are a thousand defenders, but they have already descended."

Li Jing looked at the county town and asked with a smile: "Does the general have a plan to attack the city?"

"General Duan has a suggestion, so the general might as well discuss it together."

In the newly built Central Army tent, more than a dozen generals surrounded a large table, and there was a wooden carved city on it. This was a model of Taiyuan City and was temporarily used by Zhang Xuan as Huile County.

Duan Decao introduced to everyone: "Huile County is a large county. At most, the population was more than 300,000. Even now, there are 200,000 people. The circumference of the city wall was originally thirty miles, but it was demolished and rebuilt by Liang Shishi the year before yesterday, increasing the length of the city wall to more than 40 miles. The city wall is three feet high and three feet wide and ten feet wide. The moat outside is three feet wide, tall and strong, with a wide river and deep water. It is a rare city. When the Tang army attacked the city three times, it was unable to capture this city. This is indeed a hard bone that is difficult to crack."

"How is the food in the city?" Zhang Xuan asked again.

Duan Decao said: "The richest resource of Liang Shidu is grain. He claims that the stock of grain can be eaten by soldiers for ten years. However, according to the information we obtained at the beginning of the year, the grain stored in Huile County is about one million stones, which is worthy of being the Hetao, which produces grain a lot. The official grain for several years has been spared by Liang Shidu."

"Then what is he most lacking?" Li Jing couldn't help asking.

"pig iron!"

Duan Decao laughed and said, "Lingwu County does not produce iron. Almost all the iron and bronzes of the official and civilians were exploited by Liang Shidu. Ordinary people could only cook with pots. Later, he launched a large-scale attack on the south and collected millions of kilograms of pig iron in the Longyou counties and stored them in Jincheng County. However, before he could transport the pig iron away, he was defeated by the Tang army and fled north in a hurry. These pig irons became the trophy of the Tang army. I heard that they had been transported to Chang'an last year. I don't know the equipment of the army in the city now, but the clues can be seen from the prisoners of war in Canglong Fort."

Zhang Xuan nodded, "Please continue talking!"

Duan Decao continued: "I specially checked the equipment of the prisoners of war. Half of the prisoners were wearing low-quality Turkic leather armor. It should have been eliminated by the Turks. The other half of the prisoners were wearing cloth armor. The soldiers' weapons were spears. A jujube-wood white wax pole was equipped with a spear. Most of the soldiers did not have a sword. I asked the prisoners of war that they had a sword two months ago, but they were searched, not even a dagger. Although these soldiers did not know the purpose of the sword, we can infer that they must have been re-melted by the Liang army to create the sword. This shows how scarce the pig iron in the Liang army is."

Zhang Xuan asked Li Jing again, "What is the situation of prisoners of war in Xuanwu Town?"

Li Jing smiled and said, "It's not as good as Canglong Castle. At least there are leather armor and cloth armor here. The soldiers in Xuanwu Town don't even have armor. They are all wearing cloth clothes, and there are only spears and no battle knives."

At this time, Tuoba Chici, who had been silent, added: "The leather armor is the direct army of Liang Shidu, with 6,000 people, called the Canglong Army. The army wearing cloth armor was selected from the 30,000 new troops recruited later, and was organized into the White Tiger Army. The remaining 20,000 people were divided into two, one was called the Xuanwu Army and the other was called the Zhuque Army. The name was nice, but it was actually a group of mobs, all wearing black and white cloth clothes, and their weapons included spears, hoes, wooden sticks, and all kinds of messes."

Zhang Xuan smiled slightly and said, "To put it this way, the direct army of Liang Shidu is now only 5,000 people. Are they all cavalry?"

"Report to your Highness, they only have a thousand cavalry!" Tuoba Chici replied.

At this time, everyone turned around and saw two soldiers walking in with a gray-haired old man. The soldiers bowed to Zhang Xuan, "Master, you are bringing me."

The old man knelt down, trembling all over, and said in a trembling voice: "Your Highness, the old minister is being coerced by Master Liang!"

Zhang Xuan sneered and said to everyone: "This person is Zhao Song. He was originally the Minister of Works of the previous dynasty. In the 12th year of Daye, he retired from his post and returned to his hometown Jincheng County. At that time, Li Yuan recruited him to serve in Chang'an, and Liang Shidu also recruited him to serve in Lingwu County as the prime minister. He unexpectedly chose Liang Shidu and became one of the three prime ministers of Liang Shidu and was named the left prime minister. Zhao's prime minister, I am not wrong!"

Zhao Song said in tears: "The old minister was confused for a while. He regretted it after coming to Lingwu County, but he could no longer look back. He was forced to become the prime minister by Liang Shi."

"Yeah?"

Zhang Xuan snorted, "But I heard that you married a seven-bedroom concubine in Huile County and lived a free and easy life. If you didn't happen to be caught in Canglong Castle, would you say you were being coerced?"

Zhao Song lowered his head in shame and whispered for a while: "Damn it old minister!"

"Diet or immortality is not about me, but about yourself. Do you understand what I mean?"

Zhao Song is an old fox in the officialdom. How could he not understand what Zhang Xuan meant? He quickly kowtowed and said, "The old minister is willing to make meritorious service and atone for his sins! He made meritorious service and atone for his sins!"

Zhang Xuan glanced at the city model on the seat and asked lightly: "I heard that you were the ones who were in charge of the construction of Le New City?"

When Zhao Song saw a wooden city model placed on the table, he immediately understood where his chance was. "Report to Your Highness, including the palace of Liang Shidu and the new city of Huile County, all the buildings were built by the old minister. The old minister knew very well what the loopholes in the city wall were?"

"Continue!"

"Your Highness, Huile County's biggest weakness is the four city gates. Because there is no pig iron, the four city gates are all wooden doors. They can be knocked open with giant trees or burned with fire."

"But there is a suspension bridge above the city gate, so how should we crack it?"

"Your Highness, the North City Gate Suspension Bridge is not pulled by iron chains, but ropes. There is no iron chain in the city, so you can only use hemp ropes to replace them. They will break when burned with fire."
