The two armies are located in a place where the water system is vertical and horizontal, the mountains are undulating, and the terrain is complex and changeable. Under such geographical conditions, the two sides would not be able to engage in a dignified battle, and the Chu army would not only lose its numerical advantage, but could also cause problems for itself (crowded due to the narrow terrain, or global confusion due to a local attack without rescue).

Due to the cramped terrain, many sergeants had to pitch their tents in low-lying areas that even fools could not see. The soldiers mocked, "We don't have to dig trenches, because we already have our camp in them." "What's even more terrifying is that the Chu army is camped in the northwest, which means that only by defeating the invading army can they return to Yingdu, and once defeated, they have to flee into the Dabie Mountains.

So it was time to test the talents of the commanders on both sides (in fact, there was no need to test at all, and Nangwa and others simply did not have the necessary qualities of a soldier). After inspecting the terrain and the distribution of the enemy and the enemy, he made a speech to Cai Zhaohou and the generals of the two countries with high spirits: "Although the battle has not yet begun, the situation has developed in our favor!" Feeling that he was clever and different, he pushed himself into danger - he took the initiative to play the tactic of 'die and live' (everyone in the room laughed). He and his subordinates are a bunch of braggart kings who can only deceive and lie to their subordinates.

"The widow was originally worried that the king of Chu would send the prince to lead the army into battle. However, under our deception, the prince's knot was eventually replaced by the sangwa (the Wu people released the wind before the war to say that they were only afraid of the sangwa, not the prince's knot). And now all we need to watch out for is Zuo Sima Xu, who used to be a retainer in the widow's mansion - why is his banner and team not found everywhere? Where did he go? It is estimated that he took a detour to Huaishang and copied our back road - but it doesn't matter, by the time he arrives in Huaishang, we will already occupy Yingdu. The first doctor of the state of Chu (in the battle of Gaohu) once said: 'Only by destroying the king's pawn can the state of Chu be obtained.' Zuo Sima took away the best army to fight, and only a group of slave soldiers in name were left on the opposite side. So let's fight our opponents with joy and apologies! Ten days later, we celebrated the victory together in Yingdu! ”

He Lu's speech received an enthusiastic response. He later unveiled the battle plan. In the early morning of the next day, the combined forces of Wu and Cai launched simultaneous attacks on several weakly defended areas of the Chu army. Although the Chu army was also prepared, it was unable to form a large-scale military formation due to the terrain, and Nangwa seemed to only have a positional war. As a result, when the enemy army broke through from various defense points at a rapid pace, the Chu army was in disarray.

But some of the old centurions of the Chu army—who had extensive combat experience and repeated exploits, but were never promoted—played an active role at critical moments. They can soberly observe the situation, calmly analyze the battle situation, give decisive orders, and fight bravely. Under the command of those veteran officers, the attacking Chu army was reinforced, some of the gaps that had been broken through were also filled, several commanding heights were also taken, and even inspiring victories were achieved in several places, and the once chaotic Chu army finally stabilized its foothold.

In the afternoon, the coalition forces broke through the outermost small battalions on the right flank of the Chu army, dividing and encircling several lone troops in remote places. The commander of the right wing, Shi Huang, sent an army to rescue the lone army closest to him. However, the enemy discovered the situation and immediately sent troops to stop the reinforcements, and launched an attack on the weak point of the Shihuang defensive line. Emperor Shi considered that the battle line was too long, so he had to call back that army to strengthen the defense. In the end, all the sergeants under Shi Huang's command saw how the allied soldiers rushed into the lone position like tigers and wolves, how they slaughtered their own Pao Ze brothers in a frenzy, carried the heads of the victims on the tip of their spears, and threw the headless corpses down the hillside in front of the Chu army.

The eyes of the people of Chu were full of tears, and some soldiers rushed out of the position as if they were crazy, regardless of the obstacles, and finally died in vain under the enemy's weapons. Emperor Shi was furious, but his mind remained calm, and after observing the situation, he found that it was impossible to fully hold his existing positions (several had already been lost, and the enemy was gradually encroaching on the front), so he decisively gave the order to shrink.

The commander of Wu's left flank, Fu Jie, misjudged Emperor Shi's order, believing that it was a sign of the enemy's escape; And his own unit, from officers to soldiers, was in a state of extreme excitement. The husband subconsciously waved his hand, and his two sons, Boyong and Zhong Xi, chased after him with a thousand subordinates.

Emperor Shi actually devised a plan to lure the enemy, and when he contracted the formation, he sent a light army armed only with short weapons (swords and short ge) to hide on the hillside on the east side of the retreat road from behind the position. The mountains are covered with evergreen cypress trees, which provide excellent cover for ambushes.

The retreating Chu army first passed the road down the mountain, followed by the panting pursuers. Seeing that the enemy was completely trapped, the commander rushed down from his hiding place and cut the enemy into several sections. Seeing this, the retreating Chu army also turned back and joined the battle group. Then there was a terrible massacre, and the soldiers of the Chu State seemed to have gone crazy, staring at scarlet eyes, brandishing sharp weapons, and rampage, killing people and destroying cars, even the war horses.

A quarter of an hour later, there was nothing left of the pursuers except for less than two hundred men desperately breaking through. Not a single person who failed to break through was left alive - all of them, including the husband's two sons, were cut off by the Chu people. The Wu people's hair was short, and the hair could not be tied around the waist, so the sergeants had to grab the hair, or put their hands in their mouths and carry their heads before bringing back the spoils. This well-timed victory greatly boosted the morale of the Chu army, and then Emperor Shi took advantage of the victory to recapture several more camps, and then burned the supplies that could not be taken from the camps (the Chu army had to shrink the front after all, and the soldiers could not leave the supplies to the enemy).

At the end of the battle, it was already evening, and the coalition forces drove a few wedges into the Chu army camp, and the Chu army was forced to withdraw some positions overnight; The Wu army immediately occupied those places.

Although the Wu army had the upper hand that day, the two sides did not distinguish a clear victory or defeat. The defeat of the Chu army was mainly related to the fact that the front was stretched too long. However, since the Chu people had realized their mistake, they retracted the battle line, took the initiative to retreat, and moved towards favorable terrain; Therefore, the people of Chu are full of confidence and want to show their skills in the next battle.

The next day, both sides were intensifying the deployment of troops, occupying favorable terrain, building fortifications, repairing chariots and weapons, treating the wounded, and reining the dead.
