Mei Kai came to the river to take a look, and saw that although the river receded, the road was muddy and still unable to walk, so he immediately led the sergeants to fill the road. The sergeants carried the soil on their backs, filled the firewood, and filled all the ditches and hurdles when it was dark. Mei Kai commanded the Chu army to launch a charge. When Zhu Kuai, the commander of the Qin Pass, saw that the Chu army was filling the road, he led the Qin army to the upper reaches of the river, dug the river as soon as possible, and led a stream of Dan water to a high place, and flowed through the place where the wall had collapsed. In this way, the river washed away the road that the Chu army had filled just now. In the end, the Chu army was still unable to enter the customs.

Seeing this, Mei Kai simply led the sergeants to break through the gate directly. When the soldiers saw Mei Kai going to break through the pass, they were all vying for the first credit, so they killed them all together. Seeing that the Chu army had forcibly broken through, the Qin army hurriedly retreated into the female wall and shot arrows downward. Mei Kai braved the rain of arrows, and the sergeant pushed and collided with the car and crashed towards the closed door. But the door closed very thickly, and the deadbolt was so strong that it couldn't be broken open. When he was at a loss for what to do, he suddenly heard someone shouting behind him: "General Mei, you dodge, I'm coming!" "It turned out to be Yu Sheng and his younger brother. The two prepared a large torch in the camp, and when they saw that General Mei was approaching the gate, they said, "General Mei treats us well, and we must take the lead this time." The two rushed to the front of the pass, just in time for Mei Kai to hit the door himself, Yu Sheng and his younger brother picked up the rocket on the ground, lit the torch first, and then put it at the front end of the crash, and rushed to the gate. The Qin gates were made of either jujube or elm, while the gates of Wuguan were made of iron birch, a very hard and fire-resistant wood. Moreover, a thick layer of iron sheet was wrapped on the outside, and then a large copper nail was nailed. After this treatment, even if it is covered with a layer of straw, the door will not be easily burned down, so this door is stronger than any other place, and the large torch prepared by the Yu Sheng brothers still failed to burn the closed door. It seems that the closing of the gate is not only the main line of fire, but also the main passage, so the Qin army has made careful arrangements here. At this time, Zhu Kuo saw that the Chu army had launched a fierce attack, so he knocked down the sassal wood. Mei Kai was very powerful, and hurriedly stuck the sashwager with a gun, then put it on the crash car and then ordered the sergeants to form a shield array, and transported the lit sassalwood to the gate, ready to burn the gate.

When Zhu Kuai saw that the Chu army was forcibly breaking through the pass, he commanded all the Qin troops to resist at the pass. The war drums in front of the pass were like thunder, and the shouts of killing shook the sky. Zhu Kuai came to the gate, personally picked up the sassage wood and smashed it one after another. Because he was indeed powerful, he actually smashed Mei Hong's shield array, and the soldiers of the Chu army were exposed under the noses of the Qin army, and then a flurry of arrows came indiscriminately. Mei Kai hurriedly blocked with his sword, and most of them fell. Seeing that the Chu army suffered heavy casualties, Pei Gong had no choice but to order to stop the siege.

Zhu Kuai saw that the Chu army had retreated, so he replenished the defensive equipment as soon as possible. That night, Deputy General Lu Sheng and General Yang Wu said to Zhu Kuo: "Today's Qin State, Zhao Gao is in chaos, and people have gnashing their teeth for him. Now that the second is dead, I don't know who in the Qin State can turn the tide? Zhu Kui just shook his head and didn't speak. Lu Sheng said: "Now with our little strength, it is really difficult to repel the Chu army, the general should immediately ask the imperial court for reinforcements, if Zhao Gao sends reinforcements, it means that the Qin State still has to rely on." If there is no rescue army, we should also think about the way back! Otherwise, we would have died in such an unknown way, and our family would not even be able to find a place to sacrifice? Zhu Kuo said very sadly: "What if the imperial court reinforces it?" Lu Sheng said: "Even if there are reinforcements, because Zhao Gao misled the country, the military spirit has long been lost, and I am still afraid that it will be difficult to defeat the Chu people." Zhu Kuai was stunned and said: "Now that Zhao Gao is in turmoil, the court has no backbone, if we don't fight to the death for the country, what is the difference between this and the thief?" Since ancient times, it has been difficult to know loyal ministers! I have already reported the situation to the imperial court, as long as we work together to help guard the gate, and then prepare sufficient wood, cannon stones, crossbows, hard bows, ash bottles, and gold juice, and prepare for the dawn and night, and strictly defend it, we can protect the country. And you have such thoughts, how can you say it? Lu Sheng was suddenly full of shame, and he didn't dare to say anything more.

Zhu Kuai's messenger arrived in Xianyang, and at this time, the third emperor had already killed Zhao Gao, the whole city was celebrating, and the court also had a backbone. The envoy reported to the third emperor that Pei Gong was attacking urgently. When the third generation heard that Wuguan was in a hurry, he hurriedly convened all the civil and military forces to discuss. Prime Minister Wang Juan said: "The soldiers of Wuguan are all in Zhu Kuai's hands. In the past, when Zhao Gao was there, he treated the border generals very badly. Now we should send troops to rescue as soon as possible, otherwise the Chu army will attack urgently, and if they turn against each other, it will be difficult to pull out the flag and point west. The third world said: "But Xianyang has no army to send?" Wang Juan said: "Fang Jin's plan, Your Majesty should recruit another batch of young men from Guanzhong, and then pay close attention to training, and then send them to Wuguan to fight!" The third world said: "At the moment, Wuguan is in an emergency, I'm afraid it's too late to recruit." Wang Juan said: "Now Liu Bang has come from afar, and the advantage is to fight quickly." And we are in danger of holding on, as long as we hold on, the thieves will have nothing to do with us. Now Your Majesty should first write an edict to motivate the soldiers, first arouse everyone's fighting spirit, and then cut off all the passes, although there are millions of thieves, they will not fly across the Guanshan, and then recruit the militia as soon as possible. Han said: "Prime Minister Wang's words are very safe, please Your Majesty will follow his methods." However, you can also send a few hundred loads of grain first, which can also improve morale, and there will be no danger in Wuguan! CRRC Ling Han Rong and Lang General Geng Pei also said: "Okay, send some food first, which can also stabilize the morale of the army." Wuguan is the barrier in the pass, and it is indeed the best policy to stick to it. Although Liu Bang attacked day and night, we had to calm down. All the ministers also said one after another, and they all meant this. According to everyone's method, the third emperor first wrote an edict, and then sent a special envoy to Wuguan immediately with food, and then hurried to recruit troops.

The envoy escorted the grain to Wuguan, first told everyone about the succession of the third emperor, and then took out the edict and read it out: "It is really the duty of the Qing and others to support the heavy troops at the border pass and resist the Chu army." I take your request very seriously, and am now recruiting for the Warriors. If the people and horses are ready, they will go to Wuguan as soon as possible for the secretaries to call. And now the thieves are anxious to enter the customs, hoping that you can stick to it. I sent some military rations first, hoping that the secretaries could make long-term plans. If it is protracted, the thieves will run out of food and will surely collapse without a fight. As for military tactics, I don't dare to ask rashly. ”

Seeing that the edict of the third emperor was very humble, Zhu Kuai was so moved that tears rained down, so he took the edict and then conveyed the edict of the third emperor to the whole army. Zhu Kuai then led troops to the pass, and Lu Sheng dispatched military horses to guard the danger. They block the river in the west, the mountain in the east, and the pass in the middle. The tooth generals Wang Rong and Pang Zhong led 5,000 troops to the front, and Xu Hark and Ding Ran led 5,000 soldiers to follow. One or twenty miles, the military tent company camp. Zhu Kuo personally led troops to climb the tower, waving flags and drums to boost morale. Lü Sheng also led the sergeants to the watchtower to command. The two echoed each other from afar, and the morale of the Qin army was greatly boosted.

Pei Gong saw that the weather had cooled down, and that the defense of the Qin army had undergone major changes, so he asked the ovary: "Now that the Qin army's law-abiding is very different from before, is there a master pointing out this?" The ovary replied: "No, this must be that after the new king of Qin ascended the throne, he conveyed a new order to the Qin army, and the Qin army was encouraged and their morale was boosted." Pei Gong said: "Even so, how can we stop there?" The ovary invited Pei Gong and the soldiers to come to the front of the pass to carefully survey the terrain of Wuguan, and then carefully formulated a set of plans for tackling key problems.

One morning a few days later, Pei Gong raised his account early, and then divided his troops and sent generals. He divided the Chu army into four routes: the first route was personally commanded by him, Cao Shen and Fan Xu served as the main attackers, and Zhou Bo and Ji Xin were deputies; On the second road, Mei Kai led the soldiers of the headquarters to build a pontoon bridge from the Danshui River, went upstream, and launched an attack on the pass from the pontoon bridge; The third route is commanded by Qi Gill and Wang Ling, and climbs the mountain rock from the left side of Wuguan to enter the pass; The fourth route is under the command of Guan Ying and Li Shang, and climbs up the mountain rock from the right side of Wuguan to enter the pass. The fifth route is Gongzixin to lead part of the Korean army, as a reserve to respond to all roads at any time. If several Chu armies attack together, the Qin army will definitely take care of one and lose the other, and one of them will inevitably be breached. The distribution of personnel has been decided.

For a time, the four-way army launched a general attack at the same time. Because the first time Mei Kai attacked, he didn't burn the gate, so this time Pei Gong was going to crash the gate with a crash. He led Cao Shen and others to the pass, and the shilling Zhou Bo and Ji Xin personally led the sergeants to push the crash car to the front of the pass, and the upper end of the crash car was equipped with a thick rectangular top cover, which could well prevent the Qin army from shooting arrows. When they came to the gate, they first crashed the car to the gate. One, two...... However, the Qin army arranged quite elite soldiers on the pass, and also filled the tower with wealthy elite soldiers, plus they were condescending, and they could see the army's every move at a glance. At this time, when he saw that the Chu army was attacking, he shot arrows, threw stones, threw wood, and threw fireballs in a volley, trying to deal a heavy blow to the Chu army that smashed the gate. This method really worked, and the Chu army's crash was immediately disabled, and finally ignited. After the crash caught fire, the Chu army could no longer continue the offensive and had to think of other ways.

Next, the Chu army attacked the key problems with a stone truck. This type of car is tripod-shaped as a whole, and wheels are installed at the bottom. It hung a boulder at the front end, which the soldiers pulled up and dropped in the air, and at the other end was a long log with a groove similar to a large spoon at the tip, and in it was placed a stone, or a wine jar. The stone can be driven out directly, and if it is a wine jar, it will be wrapped in linoleum. Before sending, the linoleum was lit, and the soldier let go at the same time, and the boulder at the front suddenly fell to the ground. According to the principle of leverage, you can knock out a stone or a jar of wine. When the jar falls on the ground, or closes the upper floor, it will be shattered, and then sparks will fly, like a cannonball bursting, and the lethality is also very great. Pei Gong used a number of stone trucks as the front drive. Zhou Bo and Ji Xin prepared dozens of bales of hay, poured fish oil, lit them, and then beat them out. At this time, it was the season of autumn storms, the fire took advantage of the wind, the wind was due to the fire, the smoke and flames were in the air, and the Qin army on the closed was blown up and couldn't open their eyes, and the two sides gradually became stalemate.

The second Chu army, under the leadership of Mei Kai, came to the place where the city collapsed and organized the sergeants to build a pontoon bridge. Although it is wide, a large number of Qin soldiers have been deployed in the pass, and they are intercepted upstream. Mei Li personally organized crossbowmen to shoot arrows at the Qin army to cover the engineering troops. In order to block the Chu army, the Qin army also used a hard bow and a strong crossbow to shoot at each other. This kind of pontoon bridge against the river was very difficult to build, so the Chu army used wooden boats and some large pontoon boxes as piers. Because it had to go upstream, the bridge had to be built into a folding ribbon, starting from the east bank of the river, rowing the raft to the west bank, and then building several sections from the west bank to the east bank, before the upstream connection was successful. However, in order to cover the engineering troops, hundreds of people of the Chu army died in the river.

The Chu army, which climbed the mountain rock on the third and fourth roads, also suffered heavy casualties. Because the ground was slippery, in the process of climbing, they encountered a fierce counterattack from the Qin army, and countless people fell into the valley. For a time, the Chu army of Liangyan, the former fell, and the latter followed, the sound of killing shook the sky, and the drums and horns shook the ground. It's really a narrow road, and the brave wins. After some of the sergeants occupied Takaoka, they waited for the opportunity to dodge the arrows and continued to climb. The Qin army also splashed with fish oil, this oil is not afraid of rain, the steep place slides and can't go up, and the flat place ignites a fire, and the Chu army is either burned to death, or falls off the cliff and dies.

Pei Gong commanded the main force to attack the gate, and after the stone truck had sent all the projectiles, he began to use the ladder to tackle the problem. This kind of ladder is made according to Lu Ban's method of building a car, it is tall and sturdy, can stand against the clouds, and can also overlook the enemy on the pass. The top of the ladder is equipped with an iron hook, which can be used to hook the outer edge of the castle and protect the head of the ladder from being pushed and damaged by the enemy. When Qin Jun saw this big guy, he hurriedly threw down the wood and stone to intercept it, but in front of the pass, the obstacles were also restrained, and it was impossible to intercept such a big guy.

Waiting for the cloud ladder to slowly approach the Guan Lou, a general on the top took the lead, he wielded a big knife to cut the Qin general Wang Rong who was guarding the pass into two pieces, this person was the Chu army general Cao Shen, and then he was the first to jump up the Guan Lou. At this time, another Qin general, Pang Zhong, also flew over, only to hear a roar like thunder, it turned out to be the Chu army's fierce general Fan Xu, only to see him pick up the ground and slash towards the Qin general is head-on, Pang Zhong was split in half. Cao Shen and Fan Xu joined forces, they were really brave, and they jumped into the Guan Lou. The two of them cut when they met someone, and they cut when they met a general, and the Chu army also followed and killed them. I only heard the earth-shattering sound of killing in the pass. Seeing that the Chu army was so brave, the Qin army had to retreat one after another. A group of Chu troops jumped off the gate under the leadership of Jin Qiang, Jin She, Chai Wu, Wang Su, and others, and they killed the Qin army guarding the door and opened the gate.

Zhou Bo and Ji Xin saw that the gate was wide open, so they rushed to kill in the gate. Pei Gong also immediately led Gongzi Xin to cover up and kill. At this time, Mei Kai also entered the pass from the pontoon bridge; Qi Gill, Wang Ling, Guan Ying, Li Shang and others also attacked the pass from the mountain rock. At the same time, all the soldiers launched a charge against the various strongholds of the Qin army, and the Wuguan, known as the southern gate of the Qin State, was firmly controlled by the Chu army. Strange to say, the clouds suddenly opened and the fog dispersed after a rainy and dreary weather, and I saw a bright moon looming out of the clouds. When the soldiers saw this, they were really overjoyed, so they hurried to repair the roads everywhere while the light was shining.

Seeing that the Qin army had retreated, Pei Gong asked Cao Shen and Fan Xu to continue to chase after the defeated and fleeing Qin army. After a while, the dark clouds completely dispersed, and the moon illuminated Guanshan as if it were day. The Chu army had advanced about forty or fifty miles, and the military scouts came back to report that the road ahead was getting narrower and narrower. Cao Shen was shocked: "There must be ambushes ahead." He ordered the archers to open the way to the front, and saw that on the cliff opposite the river, he clearly saw that there was an ambush of the Qin army. Cao Shen ordered the sergeant to shoot at the mountain stream. The Qin army really fell off the cliff one after another. It turned out that Zhu Kuai saw that the gate was broken by the Chu army, so he led the brigade to the narrow place to set up an ambush, they wanted to catch the Chu army who entered the pass by surprise, but who knew that the dark clouds dispersed this night, the moon returned, and the Guan Mountain was illuminated as day, and the Qin army was completely exposed to the eyes of the Chu army, but was shot by the Chu army. Zhu Kuai thought that this was the day to die Qin, so he screamed in pain, and then committed suicide by jumping into the rock.

Cao Shen reported to Pei Gong about the ambush set up by the Qin army, and Pei Gong said to the left and right: "This is really the day to kill Qin!" He stood on the Wuguan Pass and said: "Sixteen years ago, the First Emperor sent Wang Jian to lead an army of 600,000 out of this pass to destroy the Chu State. Later, the people of Chu said: 'Although Chu has three households, the death of Qin will be Chu.' 'Unexpectedly, today, the army of the State of Chu also attacked Wuguan from here. Everyone sighed with emotion, recalling that a year ago, they accepted the order of King Chu Huai and set off from Dangjun, when there were only a few thousand people, but along the way, they went through countless bloody battles and hardships, and finally entered Qinguan. This team has also grown from a few thousand to 100,000 people, how incredible it is! At this time, the bright moon was in the sky, and the Danshui River gradually returned to its former calm. There is a poem:

Unification of the first emperor, who knows how to let go?

Guanshan Qianliyue, in order to follow the Chu soldiers.

On the road in front of Wuguan, the Chu army was crowded. It took them three days and three nights before all the troops entered the pass. The ovary asked Pei Gongdao: "Wuguan is the south gate of the Qin State, and this place is very important. Who will guard us when we leave? Pei Gongdao: "After entering the customs, you must capture Emperor Qin and achieve great achievements, what is the point of guarding this pass again?" The ovary said solemnly: "No, Wuguan is known as one of the four stoppers of the Qin State, and its gains and losses are very important. No one knows what kind of danger lies ahead of us, but if we are in danger, we can still withdraw from the border from now on, which is the so-called 'grounded advance and retreat'. All must be guarded by a general! As soon as Pei Gong heard this, he felt that what the ovary said was very right, so he asked who would guard the martial arts. At this time, everyone is fighting to enter the customs, and they are not willing to stay. The ovary said to Wang Ling and Qi Ji: "The two generals know the terrain of Wuguan and Nanyang well, and it is most suitable for you to guard this pass!" Pei Gong also said: "It is exactly what I want." Wang Ling said: "We are about to enter the customs to make contributions, but let us guard this empty pass, doesn't this let us enjoy leisure?" Zifang smiled: "The general is wrong, after the army enters the customs, if there is an accident, you can't learn from General Zhou Wen back then!" Therefore, the two generals stayed to be Pei Gong's backup, and their merits were no less than those of the soldiers in front. Wang Ling listened to the words of the ovary, and suddenly realized: "I don't understand the importance of guarding, and now that Mr. has explained the importance of guarding, of course we are willing to stay." Pei Gong was overjoyed, so he let Wang Ling serve as the captain of Guan Du and the Marquis of Danshui, and Qi Gill served as the captain of Nanyang and the Marquis of Xixian, and commanded 10,000 Chu troops to guard Wuguan.
