At the beginning, Sun Ce and Zhou Yu made a plan, which was a comprehensive strategy that gathered the golden silkworm to shed its shell, attack the east and the west, hide from the sky and cross the sea, and darken Chen Cang.

The best result that can be achieved in this way is that Zhou Yu successfully opened the waterway for the withdrawal of Guangling County from Jiyang Township, Piling County, and then withdrew a large number of people and troops to Guangling County, and then came back to help Sun Ce, and then withdrew to Guangling County with Sun Ce.

Therefore, after Zhou Yu led his troops into Wu County, he carried out the means of dividing his troops, that is, he wanted to rush to Jiyang Township, Biling County, as soon as possible, that is, the section of the Yangtze River where Sun Ce's army crossed the river, looking for the opportunity to cross the river and return to Guangling County.

As long as Zhou Yu can open the river passage back to Guangling County, then he can at least return to Guangling County with the current army of nearly 30,000 and a large amount of property looted in Jiangdong this time, which can be regarded as making this Jiangdong battle rewarding.

Of course, if his side can successfully open up the retreat channel on this river, then Chen Wu's side will soon turn around and move all the coerced people on his side across the river to Guangling County.

Because at this time, most of the warships of the Jiangling Navy commanded by Cai Mao were on the side of Zhenze (Taihu Lake), and only a small number of patrol warships and a large number of river boats used to transport troops and materials were left on the Yangtze River.

Therefore, as long as Zhou Yu can hide the warships of Cai Mao's Jiangling Navy in the Jiangyin section of the Yangtze River, or solve the warships of the Jiangling Navy patrolling the Yangtze River, he may really be able to temporarily cut off the flow of the river connecting Zhenze to the Yangtze River, and block the return of Cai Mao's warships to the waterway of the Yangtze River, so as to find an opportunity for himself to withdraw to Guangling County.

Zhou Yu actually didn't mean to support Wucheng Yan Baihu at all, he just wanted to use Yan Baihu to attract Cai Mao's army.

It's a pity that Sun Wang Yuyan sent troops to block the road between Danyang City and Wu County at the beginning, and basically cut off the possibility of Zhou Yu returning to Sun Ce, so Sun Ce, who didn't have much food and grass, could only implement Plan B, preparing to lead troops to carry out the tactics of Liukou Danyang County, attack the hinterland of Danyang County, attract the main force of Zhu Wei's army, and reduce the pressure burden on Zhou Yu.

This can at least ensure that Zhou Yu can find an opportunity to open up a retreat back to Guangling County, and retreat to Guangling County with the troops, population, and property controlled by Zhou Yu, so as to give Guangling County some opportunities to develop and grow.

As for Sun Ce himself, he can only find another way to find an opportunity, save his life, and then withdraw to Guangling County, Sun Ce has already prepared to sacrifice all the troops under him, all just to cover the troops and population brought by Zhou Yu, and he can find an opportunity to withdraw to Guangling County.

However, this plan B was completely shattered under a big net laid by Wang Yuyan, and Sun Ce wiped out all his troops in one day, and even lost his own life, so Sun Ce delayed Zhou Yu for less than seven days.

However, at this time, Zhou Yu still had the possibility of realizing the two strategies of attacking the east and the west and hiding from the sky and crossing the sea, so after Zhou Yu entered Wu County, he did use the means of dividing troops to secretly withdraw the main elite he brought to the ** section of the river on the side of Jiyang Township, Biling County.

But here, Zhou Yu was still disappointed, he could not find any ships that could cross the river, and he was also found by Cai Mao's Jiangling naval army.

Although Jiyang Township, Biling County, is a narrow river crossing area on the Yangtze River, it was originally just a rural place by the river that was not taken seriously, and naturally there were no ferries, at most there were some fishing villages that relied on the river for fishing.

After Sun Cejun crossed the river here and entered Jiangdong before, in order to be precautionary, he was still prepared to secretly keep this retreat, and completely wiped out the fishermen in the fishing village where they landed.

Then Sun Cejun hid the boats they used to cross the river, and left some soldiers to pretend to be fishermen in fishing villages to guard the boats they used to cross the river, which was regarded as guarding the retreat route for Sun Cejun.

Previously, Sun Ce and Zhou Yu only knew that Cai Mao's army had entered Wu County from the Yangtze River, but they didn't know that the retreat route in Jiyang Township, Biling County had been discovered by Cai Mao's army, so Zhou Yu originally hoped to find a way to avoid the patrol of the Jiangling Navy on the Yangtze River from this retreat, and used the boats hidden here to secretly cross the river and withdraw to Guangling County.

It's a pity that Wang Yuyan and Zhu Wei attached great importance to Guangling County, where Sun Ce is located, and Zhu Wei's Three Kingdoms game map can make Zhu Wei and Wang Yuyan easily draw detailed maps everywhere.

So when Cai Mao's sailors came to Jiangdong this time, Wang Yuyan naturally asked Cai Mao to carefully find the location of Sun Ce's crossing of the river, and especially helped Cai Mao point out some suitable sections of the river.

In this way, Cai Mao, who was already good at water warfare, soon discovered that the ** section of the Jiyang Township River in Dantu County and Biling County were the two most suitable river basins for crossing the river, and the Jiangling Navy also found traces of Sun Ce's army crossing the river before after careful investigation, and then exterminated those Sun Cejun's boat guards who pretended to be fishermen.

Then the river boats originally used by Sun Cejun to cross the river naturally became captured by the Jiangling Navy, and it was impossible for Zhou Yu to use it now.

At the same time, Wang Yuyan gave Cai Mao's military orders many times, asking him to tightly seal the Yangtze River waterway, so after Cai Mao's Jiangling Navy arrived in Wu County, he also requisitioned almost all the civilian river boats and fishing boats along the Yangtze River, and naturally did not find any boats for Zhou Yu to cross the river.

Now Nadantu County has become a central operating point of Zhu Wei's army controlled by Cai Mao's navy, while the ** section of the river in Jiyang Township, Biling County has also become an important monitoring area for the Jiangling navy.

In this way, after Zhou Yu led his troops to Jiyang Township, Biling County, he was soon discovered by the Jiangling Navy left by Cai Mao in the Jiangyin River section.

Although Cai Mao's Jiangling Navy now has not many warships left on this side of the Yangtze River, as long as these warships remain on the river, Zhou Yu can only look at the river and sigh, helpless against the Jiangling Navy on the river.

Since he had lost this retreat, Zhou Yu hit the idea again on the warships owned by the main force of Cai Mao's naval army that entered Zhenze Lake.

Therefore, Zhou Yu took advantage of the fact that the main force of Cai Mao's navy was in the Zhenze Lake area, and led his troops to fill in several waterways connecting Zhenze Lake to the Yangtze River along the way, which could be regarded as blocking the retreat of Cai Mao's navy to the Yangtze River.

Then Zhou Yu led his troops all the way from the neighboring counties to Wuxi, Wu County and other places, and once again defeated these counties recovered by Cai Mao's army.

It can be said that many counties in Wu County, after Sun Ce crossed the river, encountered several changes in the city's head of the king's banner, anyway, these counties are basically unable to resist the attack of Sun Cejun, Cai Mao's army, and Zhou Yujun.

In fact, Zhou Yu's strategic intention was not only to attract Cai Mao's army to fight on land, but also to take advantage of the opportunity that Zhu Wei's army was attracted by Chen Wu's army, and wanted to quickly detour to Qiantang County, and also had the idea of sneaking up on Qiantang County.

Zhou Yu can be regarded as killing two birds with one stone, he can't deal with Cai Mao's navy hiding in Zhenze Lake, and he is not sure if he can attract Cai Mao's navy to fight on land, so he can only go to Qiantang County to find a boat to cross the river according to his original idea to Sun Ce......
