Cao Cao returned to Fancheng on the day he surrendered Xiangyang. He knew very well that a gentleman would not stand on a dangerous wall. Neither Cao's army nor Xiangyang had the power of a navy. Once the Jiangxia navy blocked the Han River, he would face great danger.

Cao Cao immediately appointed Cao Ren as General Zhennan and Prefect of Xiangyang, and incorporated 35,000 troops in Xiangyang, and appointed Cai Mao as the chief lord, Hanyang Tinghou, and assisted Cao Ren in the garrison of Xiangyang. The other surrendered officials were all named Marquis of Guannei, each with their appointments, while Liu Cong was named General Fuwei and sent Xudu to retire.

At this point, the Xiangyang Sect, among the three sects of Jingzhou, melted the ice and snow, and no longer existed.

But Cao Cao was not in a hurry to return to Yedu, but continued to consolidate his occupation in Fancheng. What he was most concerned about was the construction of warships, which was directly related to his plan for the southern expedition. In order to ensure the successful construction of the warships, Cao Cao did not hesitate to leave Cheng Yu in Fancheng and presided over the construction of the warships.

That morning, Cao Cao came to the Bishui River surrounded by dozens of generals. After Cheng Yu selected the site everywhere, he finally decided to build the main shipbuilding site in the Bishui River Bay, which was also the place where Cao Cao's ships were burned a few months ago.

Cao Cao immediately looked at the lake bay below. The lake bay was nearly a thousand acres in a radius and sparkling waves. The surrounding fishing villages had long been demolished. Tens of thousands of civilians and craftsmen were busy building shipyards, and more than a dozen huge warehouses had been built.

"Can the water depth here be built into a large ship?" Cao Cao asked with a horse whip on Huwan.

Cheng Yu had been preparing for nearly a month and had already understood these problems. He smiled slightly and said, "This lake bay is twenty feet deep and seven or eight feet shallow. It is a natural deep-water lake. There is no problem in building a warship of 3,000 stones. I have calculated that a hundred warships can be started at the same time, and a thousand warships can be built within a year."

"Where is the built warship parked?"

"Report to the Prime Minister, the warships are preparing to stop on both sides of Bishui. In order to prevent the Jiangxia army from attacking the shipbuilding station and the warships, Weichen is preparing to station 10,000 troops on both sides of Bishui, and use three iron chains to lock the river at the mouth of Bishui River, lay fishing nets under the water to strictly prevent the attacks of the Jiangxia army, but..."

Speaking of only that, Cheng Yu couldn't help but sigh slightly. Cao Cao was stunned and asked, "What else do Zhongde has to worry about?"

"I'm worried that it's easy to hide from open guns and difficult to defend against hidden arrows. I'm especially worried that the Jiangxia army will send people to dive into the lake and burn warships with tinder oil. Their tinder oil is extremely powerful and there is no way to deal with it yet."

Speaking of tincture oil, he reminded Cao Cao inverted. He turned to Cao Ren and said, "Last time you said you got two cans of tincture oil from Jiangxia Army, are you still there?"

Cao Cao refers to the last time Jiangxia army burned Fancheng Wharf with throwing pots. Two pots were not broken and obtained by Cao's army. Cao Ren has been retained to this day and has been carrying them with him. When Cao Cao asked about it, Cao Ren immediately ordered someone to pick it up.

Soon, several soldiers rushed over carefully with two pots of pots. Cao Ren presented one of them to Cao Cao, "Prime Minister, this is it!"

Cao Cao took the pottery jar and smelled it. He looked at the color again. It was light yellow and clear, which was completely different from the tincture oil that Cao army had from Puyang and Qingzhou. He then handed the tincture oil to a tooth general, "Put it on water and burn it!"

Ya was taking the pot and running towards the lake. After a moment, a raging fire ignited on the water. After staring for a while, Cao Cao sighed: "The fire is fierce and rapid, and it is indeed difficult to prevent!"

At this time, Zhang Liao said next to him: "I heard from the Jiangdong people that the initial tincture oil of the Jiangxia army was also a black and viscous thing, and light tincture oil appeared later. I guess it was transformed by some method, and a large-scale transformation must be used to use a large number of people. As long as the Prime Minister pays a lot of money, there will definitely be an insider to inform the Jiangxia army of the transformation method. This kind of thing is really hard to guard against."

Cheng Yu stroked his beard and smiled and said, "Wen Yuan's words are reasonable. If you reward them with great rewards, there must be brave men. I heard that it is producing oil in Xiazhi County, and local natives can use the local people to implement strategies. As long as we also have the turtle oil from the Jiangxia army, I am not afraid of the attack of the Jiangxia army."

Cao Cao nodded, "This plan is feasible, so Zhongde will plan it."

He turned around and said to Cao Ren: "You can cooperate with Zhongde in full and not make any mistakes!"

"Abide by the order!"

Cao Cao went to the shipbuilding station and warehouse under construction for a moment before turning back to Fancheng. However, as soon as he arrived at Fancheng, he suddenly heard a harsh bell sound from the top of the city, which made Cao Cao stunned. At this time, a guard pointed behind him and shouted: "Prime Minister, beacon!"

Cao Cao turned around and saw the beacon fire on the top of Deng Sai City and the black smoke rolled. He looked at the other side of Xiangyang City. The beacon fire was also lit on the top of Xiangyang City. He was secretly surprised. This was a signal of the enemy's attack.

Cao Ren stepped forward and asked anxiously: "This is very likely to be an attack by the Jiangxia army. I must return to Xiangyang immediately!"

Cheng Yu said: "This should be the Jiangxia navy. Since the beacon fire is lit, it is at least fifty miles away from Fancheng. The Prime Minister can deploy it calmly."

Cao Cao nodded and said to Cao Ren: "Go back immediately and mobilize the army to defend tightly on both sides of the Taiwan Straits, and do not allow the Jiangxia army to dock in Xiangyang!"

Cao Ren led his troops to flew away, and Cao Cao also entered Fancheng. He immediately mobilized 30,000 troops to strictly guard against the north bank of the Han River.

......

A fleet of 500 thousand stone warships and 20,000 naval forces rushed towards Xiangyang and Fancheng. Liu Jing stood in the fleet of large ships, looking at Fancheng on the north shore with his hands behind his back. He had already obtained information that Cao Cao was not in Xiangyang, but had been staying in Fancheng.

But Liu Jing's trip was not for Cao Cao, but for taking the initiative to challenge the Cao army, attacking the arrogance of the Cao army, and using the director of the Jiangxia army to attack the Cao army's shortcomings.

"Look at the provincial governor, Cao's army's ferry!" A personal soldier pointed at the river and shouted.

Liu Jing had already seen three ferries on the river ahead, trying desperately to drive to Xiangyang. There were many Cao army soldiers on the ferry. Liu Jing immediately ordered: "Crash and sink them!"

Three large ships rushed over in a row, shaking waves. The three ferries could not dodge and were hit by the big ship. The ferry broke. The Cao army on the ship screamed and fell into the water, and then was fished up by the small boat behind.

This scene happened on the Han River south of Fancheng, only two miles away from Fancheng. The tens of thousands of troops on the shore and the Cao army on the top of the city could see clearly, which made a chill appear on the backs of countless Cao army soldiers.

On the top of the city, Cao Cao clearly witnessed all this. He looked at the huge fleet on the river, stretching for dozens of miles. In the front was a five thousand stone tower ship. The new battle flag of the Jingzhou army was fluttered on the mast, and a red battle flag with a black battle sword above it, flying in the river wind.

"Prime Minister, that is the main ship of Jiangxia Army!"

Yu Jin whispered beside Cao Cao: "The golden-helmet general standing on the bow of the ship should be Liu Jing."

Cao Cao's pupils suddenly contracted, his eyes narrowed, and he stared at the enemy generals on the bow of the ship. The golden helmet on the leader shone in the sun, which was particularly dazzling.

Cao Cao was the first to see Liu Jing, but at this time he had no desire to pity his talents. He only had hatred in his heart, which made him grit his teeth. Liu Jing dared to show off his power in front of him?

At this time, there was another exclamation around. A fire lit up on the river surface. Jiangxia soldiers approached the shore. Jiangxia soldiers held torches in their hands and splashed turbulent oil on the ferry. Nearly a hundred ferries parked on the docks on both sides were lit by the soldiers. The river surface suddenly became thick smoke and the fire was overwhelming.

Cao Cao could no longer bear this unscrupulous provocation. He punched the city wall with a fierce punch, turned around and walked into the city, and the generals followed one after another.

Liu Jing also saw clearly when he stood on the bow of the boat. A large group of Cao army generals followed him down, and that person must be Cao Cao. Liu Jing couldn't help but laugh coldly. He could imagine Cao Cao's helplessness and anger at this time.

In the lobby, Cao Cao walked back and forth with his hands behind his back, obviously not calming his anger. Dozens of generals next to him bowed their heads and said nothing. There was silence in the lobby. At this time, Zhang Liao couldn't help but suggest, "Prime Minister, we also have tincture oil on our hands. Can we use tincture oil to burn the river and stop the Jiangxia army from provoking it."

As soon as he finished speaking, Cheng Yu's voice came from outside the lobby, "It's not appropriate to burn the river with tinea oil!"

Cheng Yu walked in, bowed to Cao Cao, and said to Zhang Liao: "I actually thought of this method just now, but I asked a few boatmen. They told me that the water flows in the middle of the Han River is quite fast, and the water on both sides is slow. When throwing objects in the middle of the river, it will soon float to both sides. The same is true for turtle oil. Not to mention that we have no ships to throw it in the middle of the river, even if we throw turtle oil on the shore, it will not flow into the middle of the river at all, and it will have no meaning."

Zhang Liao remained silent. At this time, Cao Cao sighed and said to the generals: "You all go down!"

All the generals walked down the lobby, and only Cao Cao and Cheng Yu were left in the hall. Cao Cao sighed and said, "When Jiang Xia was showing off his power in front of him, I had no choice but to go. It would be fine if I was very embarrassed. I was worried that my morale would be sluggish, but Jingzhou was so motivated. Now, if I think about it, I am a little too anxious to seize Xiangyang."

Cheng Yu smiled and said, "Actually, the problem is not to seize Xiangyang, but the Prime Minister did not expect Liu Jing's determination to resist. Now I have seen Liu Jing's strategy."

Cao Cao stopped and stared at Cheng Yu, "Please say Zhongde!"

"It is obvious that Liu Jing wanted to use the absolute advantage of the navy to control the Han River, cut off the connection between Fancheng and Xiangyang, and then attack Xiangyang in large numbers, and confront us across the Han River."

Cao Cao frowned. Cheng Yu said it was indeed right. He also thought that Liu Jing was indeed the intention. After being silent for a long time, Cao Cao asked: "If this is the case, what should we do?"

Cheng Yu sighed and said, "I really have no other way except to take advantage of the conflict between Liu Bei and Liu Jing, but I have another suggestion."

"you say!"

Cheng Yu pondered for a moment and said, "I suggest that the Prime Minister immediately transfer Cao Ren from Xiangyang and cross the Han River from Fangling County to north. While Liu Jing has not completed the deployment, only in this way can we avoid repeating Cao Hong's capture."

Cao Cao felt a little overwhelmed. He wanted to find a reason to oppose Cheng Yu, but he couldn't find it. If he dragged on, Cao Ren really had no way out.

Cao Cao felt embarrassed, and he glanced at Cheng Yu again. Seeing that he wanted to speak but stopped, he said, "What else can you say it together!"

Cheng Yu lowered his head and said nothing. Although it was difficult to speak, he still needed to remind Cao Cao.

"I suggest that the Prime Minister leave Fancheng as soon as possible and return to the north."
