Leaving Lanzhou City, Tang Xu took the caravan all the way to the east, and the weather gradually warmed up a little, and after crossing the border of the Jin Kingdom, a few days later, Tang Xu and the caravan entered the boundary of Yangcheng. Pen | fun | pavilion www. ｂｉｑｕｇｅ。 infoYangcheng is rich in medicinal materials, the streets and alleys are all pharmacies, and most of the business travelers are dealing with medicinal materials, such as cloud chips, deer antler velvet, cicada wings, Ganoderma lucidum, and ginseng, and the brewing process is also particularly excellent. After several times, he stayed in Yangcheng for more than half a month, and when Tang Xu wanted to start again, he was told that the Khitan army was about to attack, and General Du ordered that only cars, horses, and pedestrians in Fanyang City were allowed to enter and not leave.

The entourage was very anxious, and Tang Xu didn't know what to do at the moment, but the city gate was closed, and it was difficult to get out of the city, and many party members in the convoy wanted to apply for leaving the city with swagger, but they were afraid that they would be arrested as spies. Tang Xu could only let the group of people calm down and wait for the changes.

In a few days, the Khitan army really came to the city, and the army in Yangcheng also gathered in one place and stood by. I heard that there were tens of thousands of Khitan troops who came this time, and General Yangcheng Du was only a few thousand, and the disparity was so obvious that people in the city were panicked for a while, and some people even fled from the city when the city gate was changed. However, the people who fled were all killed by the Khitan army, and the Khitan soldiers who shouted and provoked them put their heads on their spears to show the public, and the tragic situation was indescribable.

For several days, General Du did not move, and when the Khitan army outside the city was also besieged, the situation became more and more dangerous, and gradually the people in the city became ill. Tang Xu couldn't bear to see the people suffer, so he risked being interrogated and began to treat the people in the city, and also took out the food stored in the convoy to help. This move was indeed noticed by General Du's subordinates, and after investigation, it was found that this was a convoy from Zhilanzhou, and Tang Xu was immediately taken away by the soldiers. Tang Xu thought that he was going to end his life, but he didn't want the soldiers to bring him to the Yangcheng Mansion, and it was Du Chongwei who commanded the entire Yangcheng defense and the Khitan army.

"Are you from the Dangxiang clan?" Du Chongwei was sitting tall and staring at Tang Xu.

"I'm Han." Tang Xu replied. Du Chongwei sighed, saying that how could the Han people be in the company of foreigners, and they came from Lanzhou, they must be spies.

"If I am a spy, why should I care about the life and death of the people of Yangcheng." Tang Xu asked rhetorically, Du Chongwei was angry and wanted to cure Tang Xu's crime, but was stopped by a person next to him.

"General, I think Dr. Tang is upright, and he has indeed treated many people in the city, and he also has the righteous act of receiving money and food, which is really the benevolence of a doctor." The man said. Du Chongwei thought about it and nodded, and let Tang Xu go back for the time being. Tang Xu was very grateful to that person, and asked for his name, only to know that the person's surname was Li Shouzhen, and he was a member of Du Chongwei's lieutenant general.

The Khitan army besieged the city day by day, and thought of a plan to cut off the drinking water in the city, and the grain and rice drinking water in Yangcheng were gradually cut off, and the morale of the army gradually weakened. After Tang Xu became acquainted with Li Shouzhen, he also began to prescribe prescriptions for the sick patients, and also took out the medicinal materials purchased by the caravan for use, Li Shouzhen was grateful to Tang Xu for his selflessness and friendship with him became deeper and deeper.

"Doctor Tang, the Khitan army is besieging the city, the people in the city are scattered, and the soldiers are also sick, how should this be good." One day, Li Shouzhen came down from the city gate to change the defense and found Tang Xu to drink and talk.

"The Khitan army came from afar, even if the siege of the city will not last long, but there is a shortage of food and water in the city, and I don't know if it can survive the day when the Khitan army withdraws." Tang Xu said.

"And the Khitans are extremely cunning and very persevering, we can't sit back and wait, we must find the right time to take the initiative, otherwise we may be defeated." Speaking of the Khitans, Tang Xu thought of the scheming Khitan woman, although she never knew her name until she died, it made Tang Xu's heart palpitate, and he would never forget the presumptuous laughter and resentful eyes.

"The city is strong, and I can't get in for a while, but there is no way to fight back at the moment, I hope God can bless my Yang City." Li Shouzhen said.

Tang Xu had no countermeasures, so he had to comfort him a few words, and when he sent Li Shouzhen out, a gust of wind blew, and the wine flag tassel at the door was blown on Tang Xu's face, Tang Xu lifted the wine flag on his face, and remembered that Zhou Yu was also pasted by the flag in the Romance of the Three Kingdoms, and he was so angry that he vomited blood. History is always strikingly similar, Tang Xu secretly laughed at himself and wanted to compare with Zhou Yu, but suddenly a thought flashed through his mind. He picked up a few leaves from the ground and threw them into the air, the leaves danced in the wind, fluttering and falling behind Tang Xu, and not far behind him was the gray earth city wall of Yangcheng, and at this moment the Khitan army was stationed a few miles away from the city. Tang Xu was overjoyed, thinking to himself, could it be that God was reluctant to die in the war when he opened his eyes? But he didn't dare to draw conclusions easily, in the next few days, every time the wind blew, Tang Xu climbed to a high place, pulling a strip of cloth to do experiments, although this strange behavior did not arouse the suspicion of others, but was seen by Du Chongwei's credulity, and he also added oil and vinegar to the secret, saying that Tang Xu was a Khitan spy, and he released signals to the Khitan people in high places every day these days. After hearing this, Du Chongwei immediately arrested Tang Xu for questioning, Tang Xu immediately denied it in the face of unwarranted questioning, and also said that he planned to use the west wind to retreat from the enemy. No one seemed to believe him.

"A gust of wind and a gust of smoke can blow the Khitans away? Don't deceive people too much! Du Chongwei sneered. Although Li Shouzhen was a little confused, he still wanted to help him persuade Du Chongwei, but Du Chongwei insisted that Tang Xu was talking nonsense, obviously wanting to communicate the news to the Khitan army and locked Tang Xu up.

Tang Xu was in prison and miserable, and no one cared about him after being imprisoned, and he was locked up in the dark prison for several days, the two armies confronted each other, and he was eager to know what was happening outside, but the jailer didn't pay attention to him. However, the jailer eats and drinks leisurely every day, which is probably quite calm, and Tang Xu can only comfort himself like this.

On this day, Tang Xu was still asleep in the prison, and he heard a commotion outside through the high and small prison window, and then the sound of human voices was mixed with the metal sound of ping-pong bells. Tang Xu opened his eyes and saw that the jailer had already run away, and he thought to himself, could it be that the Khitan army had come in? He was in a hurry, but his cell was so strong that he couldn't break through the door. At this time, a person rushed in to open the door for Tang Xu, and Tang Xu didn't think much about running out first. He ran all the way from the Yamen prison to the street, the wind was still blowing, and there were panicked soldiers and people everywhere, but he did not see the Khitans.

It's strange, they didn't get in, what are they panicking about? Tang Xu couldn't figure it out, he wanted to ask someone, but it happened that someone patted him on the shoulder at this time, and when he looked back, it was Li Shouzhen. Li Shouzhen also showed fatigue, and gave Tang Xu a piece of paper before speaking. Tang Xu opened it and saw that it was a letter of persuasion from the Khitan army that had entered the city, threatening to attack the city tomorrow, and persuading the people and soldiers in the city not to make senseless resistance, otherwise the city would be washed with blood, and no one would be left.

"How can this be?" Li Shouzhen asked. At this time, a strong wind blew, and as soon as Tang Xu let go, the persuasion book was taken off by a high roll in an instant.

"Is there brimstone and hay in the city?" Time was pressing, and Tang Xu was desperate. Li Shouzhen said that there were, Yangcheng was rich in medicinal materials, and sulfur was very common, so Tang Xu asked him to quickly collect all the sulfur and hay in the city, and prepare as many carts as possible for backup. Li Shouzhen responded, and immediately summoned his soldiers to prepare what Tang Xu wanted. With the command, the people's hearts will settle down, and Tang Xu's recent free clinic in Yangcheng has also won the favor of the people and soldiers, so everyone gathered under Tang Xu's command. On the third watch day, the sulfur and hay dry branches that can be found in the entire Yangcheng are gathered together, the number of carts is a little insufficient, the old carpenter in the city immediately began to make it, dozens of carts before dawn, and the hay bundled up mixed with sulfur are ready in time, Tang Xu let the women, children and the elderly hide in the city, cover their mouths and noses with wet cloths, and he and Li Shouzhen and the soldiers defending the city gathered in the city gate to prepare to meet the enemy.

"It's just nonsense! Are you going to drag the whole Yangcheng to the funeral? Du Chongwei came out of nowhere and scolded Tang Xu angrily. also said that Li Shouzhen did not have a coach in his eyes, and he actually followed a boy from an unknown origin to do nonsense.

"General Du, the people and soldiers of the whole city are in danger, please put down the mustard and fight the enemy with one heart." Tang Xu was anxious in his heart, seeing that there was some faint movement in front of him, he was afraid that the Khitan army was coming, but fortunately, the wind was still blowing, but it was not as strong as last night.

"Can you really retreat? If you can't retreat, General Ben will never spare you! Du Chongwei also noticed something unusual, and couldn't help but take a few steps back. When Tang Xu turned back to look for him, he was gone. I'm afraid where to hide, but if the city is broken, where can he hide? Tang Xu was amused in his heart, and he didn't care about him, he ordered the sergeant to wrap his mouth and nose in a damp cloth and prepare torches to stand by, and also ordered a team of archers to wait at the city gate.

About half an hour later, the Khitan army really spread out, and the forward who opened the way rode on horses and looked like they were winning. The Khitan army stopped not far from the city gate, and shields and archers came up from the back row and lined up, and after a while, a long formation was built, and the city was semi-encircled.

Tang Xu stood on the city tower and watched, at this time the west wind blew violently, Tang Xu was overjoyed, and he asked the soldiers to open the city gate. Seeing this, the Khitan army thought that it was a surrender, and the army also advanced a little, at this time, a row of smoke-filled carts in the gate of Yangcheng was pushed out, and the fire of the hay burned more and more fiercely by the wind, and the smoke rushed towards the Khitan army, the Khitan army did not care at first, but when the smoke gradually thickened, it was difficult to breathe, the limbs were weak, the eyes were tearful, and they couldn't open their eyes. The Khitan army retreated in panic, and Tang Xu ordered the archers in the city to shoot rockets at the Khitan army, and the Khitan army suddenly fell into a sea of smoke and fire. Li Shouzhen saw that the enemy was in disarray, and rushed out with his soldiers, and all the Khitan soldiers who could not escape were beheaded by the sword. In this battle, the Khitan army was greatly injured and frightened, and it did not take long for it to retreat north and retreat to Youzhou.
