In the summer and June, the state of Chu made all preparations for war, and the king of Chuping personally presided over the oath-taking meeting. Sima killed the Pu prisoners of war, provoked the drum and sacrificed the flag with blood, and made Yin Zibian board the flagship, and the king of Chuping announced the beginning of the war, so thousands of boats raced and marched towards Baipu.

This year's rain was particularly heavy, and the Chu people saw an endless water surface and gray sky in front of them, and the highlands revealed during the dry season were either submerged or only a green spire was exposed, and sometimes patches of tree canopy could be seen dangling under the water.

Guides guide the fleet to avoid complex waterways and navigate wide, steady waters. The Pu people in the army said that the enemy's water nature was first-class, and they could lurk motionless underwater for a day and a night with a reed stick in their mouths; When you are hungry, you catch fish to eat, and when you are sleepy, you sleep; Ordinary people's skin was soaked, and those people were fine. Chu Bing smacked his tongue after hearing this; Pu Bing finally said that only they could do the same thing and defeat the enemy in the water. When they're done boasting, they go about their business.

The fleet had already bypassed the only road, which had been destroyed by the enemy, and along the way there were some rudimentary enemy fortifications, from which the enemy ran out, nervously watching the fleet of the Chu army, shouting at them.

After that, the fleet entered the enemy's sphere of influence, and the water situation began to become complicated. The waterways are sometimes wide and sometimes narrow, and there are many forks, and there are constantly ships that run aground and run aground or disappear because they have lost their way; The enemy's water ghosts also often sneak up on some small boats unexpectedly, causing some small troubles to the Chu army. By the fifth day, the Chu army finally saw a large number of enemies.

The army was stationed on a large flat land in the middle of a lake and marsh, surrounded by water, with a trestle leading to the land, on which huge fortifications were built. The enemy was faced with a main channel that was not wide, which was the only way for the Chu army, and on both sides of the channel, around the flat land, were mud swamps, which made it impossible for them to land - if they stepped on the better places, the boots would be gone when they were pulled out, and the bad places would swallow people up directly.

Just when everyone was at a loss, Yin Zibian ordered the contents of a half-empty supply ship to be removed, and then the boat was dismantled, and a passage to the land was paved with wooden planks.

When the Chu people came ashore, they were dejected to find that they were still separated from the enemy's land by a wide swampy belt. Zifang called the officers together for a meeting. He laid out a map of the water on his table, which he had drawn during his survey last year, when the drought had connected the islands to the land, and this year's precipitation had changed many places.

The officers studied all night and there was no good way, and only went back to rest for a while when Dongfang saw Bai. After breakfast, Zibian ordered the trees to be cut down, and at the same time the Chu army sent some clippers out to reconnoitre, which quickly disappeared from view and never returned. As the sun was about to set, the soldier in charge of watching noticed an unknown person lying in the water, and when he swam closer, he recognized it as a scout sent out in the morning.

He was exhausted when he was rescued, and he told Zifang that there were many warships on the back side of the island, which could not be seen here at all, and that the enemy warships had completely controlled the course.

The generals had another sleepless night. The next day, Zibi ordered a road to be laid in the swamp that led to the island. The Chu army immediately took action, driving piles, fixing splints, and filling and compacting. The Chu army took turns to work, day and night. And the enemy laughed loudly at the Chu people, because they could not imagine how the Chu army could launch an effective attack through a small road.

But gradually they stopped laughing.

Originally, there were some small patches of land scattered scattered along the swamp belt, and the Chu army built the road to the nearest plot, and then began to expand its area while using it as a base point to build a number of roads leading to other ground. When approaching the enemy fortifications, they actually connected several separate grounds!

At this time, the enemy panicked, they felt that a huge threat was approaching, although they did not know the specific attack plan of the Chu army, but it was this uncertainty that made them panic. The enemy also began to build roads in imitation of the Chu army, wanting to seize a piece of land closer to them with them. But this kind of engineering is not what they are good at, and after a few days of work, they finally built a crooked dirt road, and the road collapsed after not stepping on it a few times.

While expanding the land area, the Chu army pulled up wood to build trebuchets. The enemy considered that it was better to take the initiative than to be passively beaten. Bai Pu's boat division then launched an attack on the enemy at a misty dawn. This was exactly what the Chu army wanted, the enemy's ships were more than enough to defend and not enough to attack, and the Chu army never relaxed its vigilance, and when the two sides were entangled, any theoretical advantage of this or that disappeared.

The morning fog makes it impossible for both sides to recognize the direction and distinguish between friend and foe, so there are many accidental injuries and accidents. In fact, the battle ended in the morning, the enemy lost most of its forces, and only a few ships were able to escape. The fog lasted until noon, and it was only then that the Chu army realized how miserable the scene was.

The trebuchet of the Chu army was also built, and the Chu people invented a projectile specifically against the wooden door wall. They made a spherical clay pot with a thin mouth, slightly larger than a fist, filled it with grease, and sealed it with lead; They soaked rattan or twine in oil, wrapped it around a clay pot like a ball of thread, lit it with a torch and fired it. The bomb was of the right weight and destructive.

The Chu army laid an improvised plank road at night, destroying the plank road between the fortress and the land, and after the preparations were completed, they started the trebuchet.

The enemy was grieving and preoccupying from his newfound defeat, when a loud roar suddenly sounded in the night sky. The flaming meteors fell from the sky, which looked particularly terrifying in the middle of the night, and the camp was immediately plunged into a sea of fire. The Pu people thought that God had sent down to punish them, and ran around in a panic. And the Chu army is very good at creating chaos at night, they beat the war drum Jin Duo to the sky, shouting while knocking; Some of the clippers were fasting with lanterns disproportionate to their size.

The enemy was completely frightened by the horrific sight, and the trestle was crowded with fleeing people, and many were squeezed into the mire. Because the trestle had been destroyed, those who ran in front were not spared, and they just pushed and fell down one by one.

After the victory, the Chu army did not continue to expand their gains, because their purpose was to pass through this waterway. The fleet then entered the hinterland of Baipu, and the enemy was no longer in danger.

The Chu army returned to the shore and marched, they were glad that they no longer had to get seasick, while the Pu soldiers preferred to stay in the rickety boats. So the allied forces marched along the water and land in parallel, and after a few days arrived at Shijin, the central city of Baipu.

The Chu army burned down the water hanging towers and hanging gates in Shijin with a catapult platform, and the enemy surrendered when he saw that the general situation was gone.

Zibian beheaded the ringleaders of the massacre of the Chu people, and brought some tribal elders back to Yingdu for the disposal of King Chuping. King Ping punished them severely, but reduced Baipu's taxes to a dispensable degree.
