Zhang Han retreated from Dong'e to Chengyang, feeling very sad, and wanted to reorganize the army to fight again. Li Youdao: "Now that Chu Kou has won and his morale is booming, we should avoid his sharp spirit." There is a shortage of food in the city here, and I am afraid that I will not be able to hold out for a few days, so I should make other plans. Zhang Han said: "What is the general's good plan?" Li Youdao: "The Dongjun city is high and wide, and it is a place for the hoarding of grain and grass, if you can defend it, you will be able to deal with the rebels for a long time, and the rebels will come from afar, the grain and grass must not be supplied, and after a long time, they will show their flaws, and then the general will gather all the soldiers and horses, and win by surprise, and he will be able to defeat Xiang Liang." Zhang Han groaned: "General Li is really high-minded, but I'm worried that the army will arrive in Dongjun and what will happen if the Chu army advances west?" Li Youdao: "In the past, Zhou Wen bypassed Xingyang and marched westward because the Qin State was defenseless, and now your army is stationed in Dongjun, and Hangu Pass is also guarded by a large army, how dare Xiang Liang advance west?" If you don't worry, I can go to Sanchuan to defend, as long as Xiang Liang is blocked, you can find a way to break him as soon as possible, and our army can turn defeat into victory. Zhang Han listened to Li You's strategy, and was very happy, so he left the partial general Gao Su to guard Chengyang, and then went out of the city with Li You overnight, one went to Sanchuan, and the other went to Dongjun.

Xiang Yu and Liu Bang were stationed at the east gate, and the next day they reported that there were traces of chariots and horses running over at the west gate and north gate. Xiang Yu ordered someone to investigate, only to learn that Li You and Zhang Han had left. Xiang Yu sent Liu Bang to attack the city and held the camp himself. Liu Bang came to the city, and Gao Su defended without a fight. The Chu army only had cavalry, and it could not capture the city for a while. Xiang Yu was very annoyed, so he personally came to the city and shouted: "Those who surrender will not die, if they resist stubbornly, after the city is broken, they will all be buried alive!" "The Qin army had heard that Xiang Yu had buried the Qin army in Xiangyi, and the sergeants were very scared, so they wanted to go out of the city and surrender. Gao Su frightened them and said, "Your wives and children are all in Guanzhong, and if you surrender, your family's lives will not be guaranteed." The soldiers worked together to defend the city. Xiang Yu was furious when he saw that the Qin army did not surrender, and immediately ordered to rush to make siege equipment.

The next day, Xiang Yu personally commanded the siege of the city, and the soldiers of the Chu army fought bravely to take the lead and brought the ladder to the city to attack the city. Fan Xu's performance was very outstanding, and he was the first to climb to the top of the city. Gao Su came to fight, Fan Xu danced the big Yue, cut him down with a Yue, and killed the Qin army, and then went down to the city and opened the city gate, and the Chu army poured into the city. Xiang Yu came to the city and ordered all the captured Qin troops to be gathered, about 2,000 people, and ordered Yingbu to dig a pit outside the city and bury them alive. Suddenly, someone stepped forward and persuaded: "General Xiang Liang will destroy Qin with righteousness, if he kills without permission, he will be no different from the brutal Qin army, please forgive the general!" Xiang Yu saw that it was Han Xin, so he smiled and said, "Do you know how many soldiers' lives will be sacrificed to capture a city?" You have no strength to restrain the chicken, how can you know the hardships of the siege? If they had surrendered earlier, this would not have happened? At this time, Liu Bang next to him also said: "General Xiang, Han Xin's words are indeed reasonable: the Chu army is a division of benevolence and righteousness, if it is killed, I am afraid that no one will dare to surrender in the future, please think twice?" Xiang Yu laughed and said: "I, Xiang Mou, if I don't obey the order, how can I convince the public?" Just the Qin army, what's the problem of killing? I should kill a lot to relieve the hatred in my heart! He didn't listen to Han Xin and Liu Bang, and ordered Ying and Pu to escort the Qin army out and bury all of them, and no one was spared. When Liu Bang saw Xiang Yu acting like this, he shook his head imperceptibly. Xiang Yu then reported the situation to his uncle, and then continued to chase after Zhang Han.

Zhang Han came to Puyang and was full of joy when he saw that the grain, grass and military supplies in the city were complete. Within two days, suddenly the military detective came to report, saying that Xiang Yu had rushed to Puyang and was less than ten miles away from the city. Zhang Han was shocked and said, "This kid is a life-chasing ghost, and he chased after him so quickly." After Zhang Han finished speaking, he thought that Puyang City was both strong and tall, and it could completely protect everyone, so he went out of the city to set up a formation, preparing to fight with Xiang Yu happily, and he must kill the majesty of this bastard boy.

After Xiang Yu and Liu Bang arrived, they saw that Zhang Han had already set up a formation. The two armies faced each other. Xiang Yu asked Liu Bang to rush to the battle first and hold down the formation by himself. Liu Bang led the sergeants to rush towards the Qin army, and he himself rode in a chariot, protected by Xiahou Ying, and rushed forward to kill. Cao Shen, Fan Hao and other generals saw Liu Bang go into battle in person, and they all rushed over on horseback desperately. When Zhang Han saw the Chu army rushing over, he ordered Hou Jian, Zhou Shuping, Zhang Qingchen and other generals to lead the Qin army to rush and kill each other. The two sides fought fiercely for a long time, although the Chu army was invincible, but because of the small number of people, it was unable to kill the Qin army.

When Xiang Yu saw this, he shook his spirits and came to kill Zhang Han in person. Zhang Han saw Xiang Yu coming to the battlefield and challenged him loudly. Zhang Han wanted to try Xiang Yu's methods, so he rode a horse and fought in person. As soon as the two fought, it was like two evil dragons biting and fighting. The two of them fought, and the golden drums on both sides sounded together, and the sound of killing shook the sky, and after fifty rounds of fierce fighting, Xiang Yu became more and more courageous. Zhang Han didn't expect Xiang Yu to be so powerful, he was really terrifying, so he gradually became weak, so he stabbed in a false way, turned around and walked away. Xiang Yu struggled to catch up. At this time, Zhang Ping, Sima Xin and other generals came together, and they entangled Xiang Yu to the death, so that Zhang Han was able to escape. Xiang Yu was aggressive, stabbing more than a dozen Qin army generals in a row, and successively wiped out and knocked to death countless pawns and sergeants. Zhang Ping and others couldn't parry, so they had to flee in defeat. Xiang Yu came and went in conflict, like entering a no-man's land.

Just when he was wantonly slashing and killing the Qin army, he suddenly found that a member of the Chu general was struggling to chase after Zhang Han, although Zhang Han had already run far away, the man was still in hot pursuit. As soon as Zhang Han chased to the side of the suspension bridge, the bridge was raised, so he jumped his horse with all his strength and jumped onto the suspension bridge. When Chu will chase after him, he will use the big axle to slash the suspension bridge cable. Suddenly, the sharp arrows of the Qin army came, and the Chu generals stopped chopping, and then reflexively killed back, and then attacked fiercely, and killed three partial generals and several armor soldiers, which was really brave. Xiang Yu was very happy, so he asked left and right: "Who will it be?" Someone replied: "He is Liu Peigong's subordinate general Fan Xu." Xiang Yu saw that this person was very brave, so he secretly remembered this name. Later, at the Hongmen banquet, Fan Yu broke into the tent, and Xiang Yu was so shocked that he sat up straight, which shows that Fan Xu's courage also convinced Xiang Yu, which is a later story.

On the battlefield, some of the Qin army saw that their general fled faster than rabbits, so they ran to the moat one after another, also wanting to save their lives, and the Qin army's formation was suddenly chaotic. The Chu army pursued and killed one after another, and won a complete victory. This battle only killed the Qin army to lose their armor and be frightened, and Zhang Han was defeated by Xiang Yu from then on.

At dusk, Zhang Han and the soldiers came to the city to inspect, and they saw the lights in the Chu army's barracks from a distance, so they were so nervous that they held their breath and watched secretly: they found that the soldiers of the Chu army were running on the flat ground outside the barracks, and they were riding horses and shooting arrows as if nothing had happened, and they didn't take the Qin army to heart at all. Zhang Han said in Qindi's dialect: "Alas, I don't want me to be defeated by this cold baby since I got out of the customs!" Zhang Ping said: "Brother, don't feel sorry for yourself, victory or defeat is a common thing in soldiers, and there are still ways to clean up this cold baby." Zhang Han said: "Having said that, the rebels are so arrogant, we have met a fierce enemy!" Suddenly a burst of thunder came, as if it was going to rain, and the soldiers all looked at the sky and said: "Let them be arrogant, and when it rains heavily, they will soak them to death, hehe!" Although everyone was scolding, they didn't dare to amplify their voices. Zhang Han saw that everyone was very depressed, so he muttered: "It would be nice to be able to soak them to death." ”

The next day, Xiang Yu continued to come to challenge, but the city gate was closed, and Zhang Han did not dare to fight. The Chu army went to the city to scold, and suddenly it rained, so Xiang Yu asked the sergeant to brave the rain and scold. But the rain became heavier and heavier, so Xiang Yu had to order the sergeant to return to the camp to avoid the rain. Zhang Han saw that the Chu army did not come to scold because of the rain, so he came to the city again to watch, only to see that the water on the ground was flowing into the moat, and the surface of the moat slowly became wider. ”

The next day, it rained for another day. After getting dark, he suddenly heard a shouting and killing sound from the Chu camp, Zhang Han thought that Xiang Yu was going to attack the city, so he hurriedly came to the city to watch, but found that the Chu army was still training. It turned out that Xiang Yu's training didn't care about the wind and rain at all, he said that he would train when he trained, and the military order was very strict. Zhang Han looked at the fierce Chu Jun, and said to the left and right: "What kind of master there is, what kind of grandson there is!" Although Xiang Yan was defeated back then, his prestige still shocked the world, this Xiang Yu is really not a grandson of Grandpa Rao! Sima Xin said with a smile: "Since ancient times, soldiers have come to block, and water has come to the earth." Although he is arrogant, he can't cross the wide moat, this is God bless us! When Zhang Han heard this, he looked at the moat again, and said, "Although we are safe, what if the river dries up?" You can't wait to die here, can you? One sentence made everyone worry again. Seeing that the generals stopped talking, Zhang Han suddenly sneered: "God is indeed helping the Great Qin Kingdom!" I've got a way to deal with them! All the generals felt inexplicable, Dong Yi said: "Xiang Yu is so tall, even if he drowns others, he can't drown, general, what can you do?" Zhang Han smiled mysteriously: "Now that the autumn rain continues, the water of the big river will inevitably surge, hehe...... Haha......"

The next night, in the Chu camp, Xiang Yu, Liu Bang and others were discussing the method of attacking the city, and suddenly someone came in to report that a son with extraordinary bearing came to ask for a meeting, and he also led hundreds of young people. Xiang Yu said: "This is here to join the army." So he met with the son. It turned out that it was none other than Chen Ping, the former servant of the Wei State. After Xiang Yu saw Chen Ping, he saw that he was chic and elegant, and he was suave, so he asked, "Who is Mr. from?" Coming in the rain tonight, there must be some advice, right? Chen Ping said: "Under Chen Ping, the family is a family." Xiang Yu was shocked: "Mr. Mo is not Chen Ping, the servant of the Wei State?" Chen Ping said: "It's under it, but the Wei State has already ......" Xiang Yu and Liu Bang were very happy when they heard that he was Chen Ping, the former servant of the Wei State, Liu Bang said: "I heard that when Mr. was in the Wei State, the Wei State was still standing, but later the King of Wei did not listen to Mr. 's words, and the great cause was wiped out in an instant, and the country ceased to exist, which is a pity!" Xiang Yu said: "Yes, Mr. is here tonight, there must be a teaching, right?" Chen Ping said humbly: "The two generals have a good reputation, and I, Chen Ping, have nothing outstanding, but I just like to use my brains when I encounter problems, alas!" The past is unbearable, the Wei State no longer exists, it is really painful! But when I come tonight, I have something to tell you! Xiang Yu asked what was the matter. Chen Ping said: "Now that the autumn rain continues, the water of the big river will inevitably surge, plus there is water everywhere, and the camp of the Chu army is so low-lying, if Zhang Han attracts the river water to flood, then ......" Xiang Yu and Liu Bang were taken aback when they heard Chen Ping's words, and quickly ordered the camp to be moved.

Just when everyone was moving the camp in a panic, there was another person outside the tent, who was also preparing to tell Xiang Yu about the flood, and this person was Han Xin. But when Han Xin came to the gate of Xiang Yu's camp, he had already heard the herald come out and say loudly: "General Xiang has an order, move the camp quickly to prevent Zhang Han from leading water to flood!" Fast! Fast! Han Xin was shocked, thinking that this was Xiang Yu's idea, so he hurriedly packed up his things.

The Chu army moved the camp in the rain, and as soon as the camp was moved, the sound of the waves was heard, and the flood suddenly flooded the camp that the Chu army had set up just now. When the officers and men of the Chu army saw the scene in front of them, they were all stunned. It turned out that it was the Qin army that secretly attracted the water of the Yellow River in the north, and the moat was suddenly dozens of zhang wide, and the river flooded the moat and then hit the low-lying place, and after a while, the ground where the entire Chu army was encamped became a water town. Seeing this, Xiang Yu and Liu Bang also felt a chill down their backs, so they thanked Chen Ping again and again. Chen Ping said: "Now that Zhang Han floods Puyang, not only to block the Chu army, but also to protect himself, I think in a short period of time, the river cannot recede, the general should report to Wu Xinjun as soon as possible, and ask him to find another way to break the enemy, right?" Xiang Yu immediately sent someone to report to Wu Xinjun.

Xiang Liang was in Dong'e, and when he heard that Tian Rong had driven out the traitors, he sent people to Qi to ask for troops to attack Zhanghan. However, Tian Rong refused to send troops immediately on the grounds that the domestic situation was unstable. At this time, Xiang Yu had already sent someone to report to his uncle about Puyang. Xiang Liang weighed it again, so he decided to leave Dong'e, so he ordered Xiang Yu to stop fighting, go south to join him, and then lead the Chu army to the south.

Xiang Liang came to Dingtao and met Xiang Yu and Liu Bang to greet him. When they came to the city together, Xiang Yu told his uncle about the flood and Chen Ping's rush to rescue. Xiang Liang heard that there were such strange people, so he immediately met Chen Ping. Chen Ping is gentle and elegant, neither humble nor arrogant, Xiang Liang loves him very much, and because he has made great contributions, he was named a lieutenant in person. Han Xin was right in front of him, and when he saw that Chen Ping was an official because of the relocation of the camp, he was very unhappy, but no matter how big his emotions were, there was no way, so he could only be silent. Xiang Liang set up the military camp on a wide flat land in the south of Dingtao City, and then summoned the generals and said: "Zhang Han's army is in Puyang, Sanchuan must be empty at this time, if my hundreds of thousands of troops advance westward, Hangu Pass will be at your fingertips." Before the words fell, the spy came to report that Li You had recruited soldiers and horses in Sanchuan in an attempt to block the Chu army. Xiang Liang was shocked when he heard this: "This Li You is indeed not ordinary, he used to defend Xingyang, which made it impossible for Wu Guangjun to advance, otherwise the Qin State would have died a long time ago." Marching Sima Song Yi said: "Although Zhang Han has suffered defeats, his strength is still very strong, once our army advances westward, what if he attacks it?" The general should sit on the calm Tao, wait until the water of Puyang subsides, and then fight a decisive battle with Zhang Han, and only after defeating Zhang Han can we rest assured that we can go west. In addition, you still urge Tian Rong to send troops together, if Chu and Qi unite, we will have a better chance of winning. Xiang Liang felt that Song Yi's words were very reasonable, so he immediately sent someone to the Qi State.
