As soon as Zhang Bao and Guan Xing saw this fleet, the smiles on their faces stopped abruptly. The size of the fleet was not large, only twenty ships, but each ship was more than twice as large as an ordinary warship, and the construction was very strong.

Not only that, but the surface of the warship was also wrapped in a shiny iron sheet, of course, the iron sheet was only a thin layer, and below was a thick layer of leather, which was the ironclad ship that Zhu Ran had secretly built recently.

On the iron sheet, there are countless small holes, large and small, which are reserved for the soldiers to use to release arrows, this kind of powerful warship is by no means comparable to ordinary warships, and its power is more than ten times that of it.

The ironclad ship quickly rushed into the warship fleet of the Shu army, and there was an unorderly rush, and at the same time, countless arrows shot out of the ship.

In an instant, a large row of warships on Zhang Bao and Guan Xing's side were knocked over, and the soldiers fell into the water one after another, and there were countless soldiers who were hit by arrows, but the opponent's ironclad ship was not damaged at all.

Seeing this, Zhang Bao hurriedly ordered torches to be thrown into these ironclad ships, but because the hull was protected by iron sheets, the torches could not be completely ignited at all, but made these burning ironclad ships more powerful than before.

At the same time, Zhu Ran led other warships to launch a full-scale attack, shuttling on the river at will with great agility, constantly separating and encircling the warships of the Shu army, and encroaching on them one by one.

The warships of the Shu army were in chaos, and went to rescue the left side, and there was a cry for help on the right side, and they were about to go to the right again, but the oncoming Jiangdong warships were coming quickly, and they were unable to protect themselves, and they were in a mess.

"Zhu Ran is really cunning!" Zhang Bao was so angry that he shouted, because he couldn't get close, the Zhangba snake spear in his hand was useless at all, and he was so angry that he jumped high on the warship.

"Brother, I'm afraid that I won't be able to defeat the enemy, so let's retreat quickly and discuss it again!" Guan Xing felt that the momentum was not right, and said to Zhang Baojian.

"Retreat from the enemy at this time, won't you let those uncles and uncles see the joke!" Zhang Bao was a little unwilling.

"Brother, you have to preserve your strength, don't let the saint's hard work go to waste." Guan Xing is loyal and righteous, and his face is full of sincere persuasion.

Don't look at the face of the eldest uncle Liu Bei, the current situation, it is indeed impossible to fight, blindly brutal, that is the courage of the horseman, Zhang Bao had to order, sound the gong to withdraw the troops, and the warships of the Shu army immediately retreated back in a hurry. In the panic, the warships collided with each other, which also caused unnecessary losses due to the ship's capsizing and falling overboard.

Zhu Ran took advantage of the victory to catch up, and the Wu army was full of morale, concentrated firepower, and even surrounded Zhang Bao's warship.

"Zhu Ran, this guy, dare to bully my grandfather and me!"

Zhang Bao was really angry, and immediately ordered his leader to lead the warship and desperately approach an ironclad ship, and the two brothers jumped up, used the weapons in their hands, and cut through the ironclad protection, killed the soldiers hidden inside, and seized the ironclad ship, so that they were finally able to escape.

A water battle lasted for a full day, ending with Zhang Bao and Guan Xing's fiasco and retreating, and went back to count the men and horses, and the Shu army lost more than 30,000 people, and the warships that were sunk and snatched away were as many as more than 300.

And Zhu Ran's side only lost more than 5,000 people, including an ironclad ship, which can be described as a complete victory and a great boost in morale.

The two young generals, Zhang Bao and Guan Xing, lost their spirits, lost face, hung their heads, and couldn't eat depressed. At this moment, the two have realized a practical problem, even though this side has an advantage in troops, but the other party is familiar with water battles and is well prepared, and it is impossible to win in a short time.

The two brothers hurriedly reported the situation to Liu Bei, and did not dare to rashly take offensive actions, while Zhu Ran expected that Zhang Bao and Guan Xing would not dare to attack in a short time, so they boldly divided 10,000 soldiers and horses to support Cui Yu, who was guarding the stone wall on the west side.

"An army of 100,000 has failed miserably, how is this good?" Liu Bei was shocked when he heard that Zhang Bao and the others could not win, and it was simply unbelievable. I thought that the two nephews would be able to inherit their father's ambition and provoke the training of a new generation of generals, but I didn't expect that they were still young in the end, and they couldn't even beat Zhu Ran.

"Holy Lord, the two generals are not used to water warfare, and it is reasonable that they will be defeated." Strategist Cheng Ji hurriedly comforted.

"Why didn't you say it earlier?" Liu Bei's face was full of displeasure.

Cheng Yi looked ashamed, bowed his head and said: "This, the minister is not thoughtful, please punish him!" ”

At the moment, the army is fighting, and punishment can't solve any problems, Liu Bei waved his hand and said: "Forget it, what other good strategies do you have?" ”

"General Liao Hua has been with General Guan Yu for a long time, and he should know about water warfare, so he can be transferred from the rear to command the naval army." Chen Zhen slapped his head and stepped forward.

Why didn't you say it earlier?!

Liu Bei asked indignantly in his heart, alas, he always thinks of these questions after the fact, what a bunch of rice buckets! Liu Bei held back his anger and did not attack, nodded helplessly, and hurriedly sent someone to the rear to pass Liao Hua to come.

At this time, Liao Huazheng led a group of soldiers and horses to be stationed in Linjiang, and it took more than ten days to come and go.

Wu Ban and Zhang Nan heard that Zhang Bao's naval army had been defeated, and they did not dare to take action for a while, and their hearts became more and more impatient.

After resting for a few days, Wu Ban and Zhang Nan once again led a large army to attack this stone wall, Cui Yu received the support of Zhu Ran's troops and the replenishment of strategic materials, full of confidence, tenaciously faced the battle, and repelled Wu Ban's large-scale attacks again and again.

Wu Ban foamed so much that he couldn't even drink water, and he was very anxious. Zhang Nanjian said: "General, the enemy army is so stubborn, if you want to win, you must use tactics. ”

Wu Ban didn't want to lose his troops like this, nodded and asked, "From the general's point of view, what should I do?" ”

"There is a way that the thief captures the king first, and from the point of view of the last general, you should kill Cui Yu first." Zhang Nanjian said.

Who doesn't know this? Wu Ban looked bitter, and his brows furrowed into a pimple: "This plan is okay, but how can Cui Yu kill him behind the stone wall?" ”

It can be like this, Zhang Nan stepped forward and put forward his own ideas, Wu Ban's eyes lit up suddenly, nodded and agreed, and began to prepare. Of course, there is also a question in my heart, why didn't you say it earlier!

The next day, Wu Ban's army again approached the stone wall, but this time it did not attack immediately, but sent a team of thousands of soldiers, man by man, holding their shields high, and stood quietly not far from the stone wall.

Looking at such a dense shield below, Cui Yu couldn't figure out what Wu Ban wanted to do for a while, the other party's defense was tight, and bows and arrows were useless, not to mention that there were not many bows and arrows, and the stones could not be thrown so far, so this army could only stand below.
