But Guan Yu originally had an iron chain crossing the river.

It is a real iron chain across the river. The frogman troops paid a heavy casualty price to nail wooden stakes in the shallow river water, and then connected to the shore with iron chains as thick as arms to intercept passing ships on the river surface.

Countless long-range crossbows were placed on the shore to specifically shoot ships sailing on the river. Whether it is military or civilian ships, it is guaranteed that no one can successfully go downstream. Naturally, it is even more impossible to go upstream to provide support to the Yizhou rebels.

On the Eastern Wu side, they tried to cross the river several times to destroy the crossbows on the shore, but after seven or eight rounds of battle, they were still no match for the Han army in the land battle. Instead, Guan Yu picked up several small victories and killed more than 2,000 enemies.

In desperation, the Eastern Wu side could only set up a crossbow on the shore to shoot against Guan Yu, but this was a pure battle of attrition.

However, the Han Dynasty's national strength was far greater than that of the Eastern Wu. Secondly, Changsha County was not the core area of ​​the Eastern Wu. The domestic economic and Taiwan of the Eastern Wu relied on maritime transportation, and the development of the coastal areas and inland areas was extremely unbalanced, resulting in Changsha County and even the four counties in Jiangnan as a whole being poor, and the local finances were not rich. The Yangtze River channel was blocked, so it was difficult to transfusion blood from Yangzhou.

On the contrary, Guan Yu's Jingzhou Corps can easily obtain blood transfusions from Nanyang and even Luoyang, and it will be impossible for Changsha County to fight for consumption.

The incident happened suddenly, and the Eastern Wu did not expect that Guan Yu was so bold. At a critical moment like destroying Shu, he suddenly shot them with a shot, but he was not ready for war at all.

Even though Sun Ce sent his confidant Zhou Yu to personally supervise the battle with Guan Yu, inadequate preparations means insufficient preparations. Not to mention Zhou Yu in this war of attrition, Bai Qi and Han Xin are completely helpless in the resurrection.

In fact, before being ordered in the face of danger, Zhou Yu also held a strategic seminar on the founding of the country with Sun Ce and Zhang Hong, considering whether it was necessary for them to attack Hefei, or simply harass the border areas of Qingxu, Jiyou, and You, in order to share the pressure on the four counties in Jingnan.

However, almost all the ministers opposed this.

After all, it is obvious that Guan Yu blocked the Yangtze River in order to allow the prince to better destroy Shu and annex Yizhou. It is necessary to maintain proper vigilance in the direction of Yangzhou, but the Yizhou area is destined to return to the Han Dynasty sooner or later. They will not fight a full-scale war with the Han Dynasty for the sake of Shu.

Besides, they also heard that the Han Dynasty was implementing an official system that was changing with the old and the new. Even if a relatively young general like Zhao Yun, who was a relatively young man, would have to be transferred to Beijing if he did not retire.

In other words, soon, the Han military will undergo a major blood change. The handover period will definitely be when the Han military is weakest. Even if we have to fight, can't we fight at that time?

Now, the old Han army is all here and is facing a retirement crisis. Before retiring, these things must be thinking about doing something big and letting themselves write two more in history books. In other words, the Han army is likely to be the strongest and most warlike years in the past few years and the next few years.

Therefore, the national policy formulated by the Eastern Wu side is to not only avoid counterattacks against the Han Dynasty, but also to maintain restraint as much as possible and not to easily let the veterans of the Han army pull themselves into the quagmire of war.

The total economic output of the Eastern Wu was not as good as that of the Great Han Dynasty, but the growth rate was faster than that of the Great Han Dynasty. Therefore, the small court of the Eastern Wu always felt that time was in me, which was the right thing to do.

Therefore, Zhou Yu's strategic purpose at this time was to restore the Yangtze River route, in order to sweep the wealth of Yizhou and add a little disgusting to the Han Dynasty.

At the same time, the torch called freedom was lit in Yizhou.

However, it is really hard to cook without rice. Sun Ce gave him all the support except help. This kind of fireworks across the river is ultimately a fire density. Whether it is a crossbow or a catapult, both sides consumed very quickly. Soon, Zhou Yu could not hold on.

As for the strategy, strategy, courage, and commander ability, it cannot be said that it is useless, but it is better than nothing.

The aid supplies from Yangzhou were not transported, so Zhou Yu could only build a factory in Jingnan Shijun and organize craftsmen to hurry up and produce crossbows and catapults for the needs of the frontline.

But he felt a bit tragic as he used all his property to challenge Guan Yu's pocket money.

As for Guan Yu, he originally received the imperial edict from the prince first.

Although it was an accident, it was still calm. He smiled with satisfaction for Liu Bei to do whatever he should do, and even prepared to die happily.

Even if he is as arrogant as a lord, he doesn't think he really has the chance to conquer Changsha. After all, Zhou Yu's navy has been pulled out. It's too difficult to cross the river. Even if he can cross the river, the Yangtze River navy can easily cut off the river water, causing them to starve to death by losing supplies from behind.

The so-called Changsha County Duke clearly forced himself to die, and was clearly blocking Liu Bei's mouth.

The court has its own big strategy, and the emperor has its own temple calculations. Now, the trains, steam engines, etc. have been developed. In a few years, the national strength of the Han Dynasty and the Eastern Wu will be further expanded. That is the time to truly unify the Eastern Wu.

How could Guan Yu destroy the country's grand strategy for his own life?

So he did whatever he should do, and had no idea of ​​risking his life to fight Changsha. While waiting for his death, he wrote a letter to his wife, children, daughter-in-law, relatives, Liu Bei and Zhang Fei, and even Sima Yi.

Even after a while, he even smiled and went to the coffin shop to choose a coffin for himself, and even lay in with a smile to measure the size.

Then, he received the emperor's edict.

He was so stupid.

He immediately took the imperial edict to Guo Jia: "Fengxiao, please help me see what the emperor means. What is this? It is impossible for Guan to completely change the national policy just because of Guan's life. Let's fight against Eastern Wu in advance. In this way, isn't Guan a sinner for the ages?"

Guo Jia was also stunned after reading the letter. After a long time, he howled and cried.

"What do you mean?"

"I still think that I can be a military supervisor for you, and only do some iron chains across the river, and end up in vain. If I do today, you are a fake Huang Yue and the commander of the military affairs of the three continents. Am I really going to become your master from a military supervisor? What kind of evil am I doing? I am not in good health, Yun Chang, it seems that your coffin is chosen for me now!"

"I really want to fight? Your Majesty is so kind, Yu has no choice but to repay him. So how can he still..."
