But in Xiakou, Liu Bei saw that Liu Yi was either studying how to streamline the curved plow every day or studying printing. Although he felt that printing was indeed a big deal, it was the time of a great battle with Cao's army that Liu Bei tactfully proposed, hoping that Liu Yi would put down these things temporarily and study them after defeating Cao Cao. Everything is the main thing to defeat Cao Cao.

Actually, before the decisive battle with Cao Cao, Liu Bei and Liu Qi were basically not used. Zhuge Liang had already said what he should do, and Liu Yi also added some more.

Do you want to tell Liu Bei that this is actually a matter of fire?

It was finally fulfilled after it was said. I am afraid that Liu Bei should treat him like Zhuge Liang. How could he have that ability? Besides, once it is leaked and a big thing is ruined, he will really be unpredictable.

He was a little helpless, but since Liu Bei had spoken and these things were not in a hurry, Liu Yi could only give up the improvement for the time being and took Wei Yan to the water village dock to think about what to do next?

Liu Bei didn't say what he wanted, but he just felt that Liu Yi shouldn't study printing techniques and farming equipment at this time, but Liu Bei never thought about what he wanted to do.

In the Battle of Red Cliff, Liu Yi prepared hundreds of fast boats for Jiangdong. With these fast boats, as long as Cao Cao had an iron chain boat like in history or the Romance of the Romance, Zhou Yu could seize the fleeting fighter opportunity, and the battle would basically end. After that, he seized the territory. With the ten warships made by Liu Yi as a surprise soldier, it would not be difficult to capture Jiangling. If you count this way, if you want to expand your business, there will be only Xiangyang left in Jingzhou. If you fight northward, Liu Bei will not be able to swallow it.

Xiangyang...

Liu Yi has seen Xiangyang City Defense, which is a strong city. Although his craftsman skills can bring attributes to items, they cannot break free from the constraints of this era. If he really wants to fight a strong city like Xiangyang...

Liu Yi did not go to the dock, but just asked someone to get a standing table (similar to an easel), and came over with pen, ink, paper and inkstone, stuck a piece of Cai Hou paper on the table, frowned and picked up the pen, and outlined the structure of Xiangyang and Fancheng based on memory.

Liu Yi saw the structure of Fancheng when Liu Bei asked Liu Yi to strengthen the defense of Fancheng City and had already remembered it in his heart. As for Xiangyang, Liu Yi lived there for a while. Although many places were not allowed to be approached, Liu Yi's current vision is enough to deduce the overall structure of Xiangyang City based on those places he has been to.

"Sir, is this Xiangyang City?" Wei Yan stood beside Liu Yi, looking at the drawings drawn by Liu Yi, and said in surprise.

"Yeah." Liu Yi nodded. Xiangyang City was close to the sergeant, and three or four floors were as high as that of a building. In this era, this was already a rare city. Liu Yi had never seen a big city like Luoyang and Chang'an, but it was probably not too far apart.

"Sir, are going to suggest that the lord attack Xiangyang?" Wei Yan's eyes lit up and he looked at Liu Yi and said, "He has now been crazy about the position of a lieutenant. He is considered Liu Bei's general, but he is still listening to Liu Yi's side.

"How many soldiers are there under the emperor?" Liu Yi shook his head: "But if you want to attack Xiangyang, it is best to attack with one go, otherwise the longer it will be, the more difficult it will be! If the emperor can successfully capture Jiangling, I suggest that the emperor gather troops, advance along the water, and take down the land of Xiangfan in one fell swoop."

As soon as the Battle of Red Cliff ended, Cao Cao was busy running away, and the morale of the Cao army in the Jingxiang area would inevitably be depressed. This is the best time to attack. If Cao Cao stabilized his position and began to set up defense lines in Xiangyang and strengthen the city walls, it would be difficult to attack Xiangyang at that time.

Moreover, if Liu Bei could conquer Jiangling and Xiangyang with his own abilities, there would be no problem of borrowing from Jingzhou. Guan Yu's loss of Jingzhou was also a key node for the decline of the Shu Han regime from its peak.

"Wen Chang, if you come to guard Xiangyang, how should you guard?" Liu Yi looked at Wei Yan. He knew that Wei Yan was depressed recently because Liu Bei failed to pay attention to him. However, he was only responsible for recommending such matters. Liu Yi could not control other issues, and he could not control Liu Bei's thoughts.

"If I come to guard..." Wei Yan heard this, he looked at the figures of the two cities drawn by Liu Yi, and his eyes suddenly lit up: "If it were me, we would use the navy to communicate with the two cities. If the enemy attacked Xiangyang, we would transfer the soldiers of Fancheng to Xiangyang. If the enemy attacked Fancheng, the other way around."

"If you can get these two cities in the future, you will set up a floating bridge between Xiangfan." Liu Yi looked at Wei Yan, nodded and smiled. This is also the reason why he drew the two cities of Xiangfan together.

Why did Liu Bei station troops in Fancheng when Liu Cong had not surrendered? It was because there was only one water separation between the two cities, and they could help each other. Moreover, Cao's army was not accustomed to water wars. With these two cities alone, Cao Cao had millions of powerful troops, and it was difficult for him to break through these two cities.

But now if they are to be attacking the enemy, the first thing they need to do is to cut off the connection between the two cities. From this point of view, ten warships are obviously not enough. Liu Yi must make a more complete fleet, not only large ships, but also small ships to support them.

"What do you need to attack?" Liu Yi asked. He did not have a deep study of military tactics, and his combat experience was limited to the few times he defended Mocheng.

"This..." Wei Yan was a little embarrassed and looked at the two cities and said, "First of all, there must be a navy army to cut off the connection between the two cities."

Liu Yi nodded. He had already thought of this, and it was easier for Liu Bei to build a navy army than Cao Cao to build a navy.

"Secondly, if the siege equipment and food are sufficient, it will also require an army of 80,000!" Wei Yan thought for a moment and said affirmatively.

"So many?" Liu Yi raised his eyebrows and looked at Wei Yan. Although Wei Yan was quite crazy, he was not a person who could speak loudly. In this regard, he was more rational than Guan Yu, but the 80,000 army, let alone now, even Liu Bei from Jingzhou might not be able to take it out.

"Sir, the last general knows the defense of Xiangyang City. With the strength of Xiangyang City, if there is no 80,000 troops, the last general will not have the confidence to take it down." Wei Yan said with a wry smile.

Eighty thousand!

Liu Yi understood a little why Liu Bei didn’t take Xiangyang anymore. He thought about the war too simply. It’s not that Liu Bei didn’t want it, but that he couldn’t take it at all. It seems that he was thinking too much. Now he should think about taking Jiangling at the lowest cost!

Of course, what Wei Yan said was that under the conditions of the Cao army's full preparation, so many people were needed. If Chibi was defeated, it might not be needed. As for how much it was needed, Liu Yi didn't know. There were too many things to consider in it and he couldn't count it. When Zhuge Liang came back, he should discuss it with him, but with Zhuge Liang's personality, if he was not fully sure, he might not agree to this plan.

Liu Yi put away the Xiangfan map and prepared to use it again in the future if he had the chance. He posted another one again and prepared to draw a map of Jiangling, but he saw Liu Bei bringing Guan Yu and Zhang Fei to the water village.

I don’t know if the other party is here to look for him, but Liu Yi still stood up, took Wei Yan to meet him, bowed to Liu Bei and said, “Where is the Emperor’s journey?”

"In another five days, it will be the day to make an appointment with Kong Ming. I don't know what the Cao army is now. I'm going to take a boat to find out what is going on with Bo Yuan?" Liu Bei smiled at Liu Yi.

Five days?

Liu Yi wanted to refuse, but looked at Wei Yan who was eager to try beside him and nodded, "It just happened that there was nothing wrong, so I accompanied the emperor to see how Cao's army was prepared so that I could think about the way to crack it in the future."

There should be no danger.

Liu Yi personally picked a small boat with a cabin in the water village. Although it was a small boat, the boat was quite fast. Liu Bei did not refuse Liu Yi and Wei Yan with him, so he asked Wei Yan to be responsible for the boat. The four of them entered the cabin and talked.

The cabin is not big, but the interior gives people a feeling of being quite spacious. After Liu Bei entered the cabin, he said incredible: "I had known that Bo Yuan had a magical skill, but every time he saw it, it was still a sigh."

"Uncle Emperor is so serious." Liu Yi smiled and said modestly: "Cong Ming will come back in five days?"

"Yeah." Liu Bei nodded and looked at Liu Yi and said, "Is there something wrong with Bo Yuan?"

"I have something to discuss with Kong Ming." Liu Yi nodded.

"What's the matter?" Liu Bei smiled and said, "Can Bo Yuan talk to Bei?"

Liu Yi nodded. Even if Zhuge Liang agreed to this matter, Liu Bei had to nod. He immediately took out the Xiangfan defense map from his arms and spread it on the low table in the cabin: "Yi had previously studied whether it was feasible if Cao's army was defeated and wanted to attack Xiangyang. He asked Wen Chang for a while. Wen Chang replied, "If you attack Xiangyang, you must cut off the contact with Xiangfan with a navy, and then you still need 80,000 troops to conquer Xiangyang. However, this is due to the sufficient defense of Xiangyang. If Cao Cao's army is defeated and his morale is damaged, if our army takes the opportunity to attack Xiangyang, how many troops will be needed? Yi does not understand military tactics, so he wants to discuss with Kong Ming."

"This..." Liu Bei looked at the map given by Liu Yi, which was quite detailed. When he heard this, he smiled bitterly and shook his head without saying anything.

He has been in Jingzhou for nearly ten years, and of course he knows the importance of Xiangyang and the solidity of Xiangyang. When he retreated from Xinye to Fancheng, he was the idea of ​​uniting with Xiangyang and fighting against Cao's army. Unfortunately, Liu Cong's surrender caught Liu Bei off guard and could only give up this natural barrier.

Now that Liu Yi proposed to attack Xiangyang, Liu Bei could only smile bitterly.

"No?" Liu Yi looked at Liu Bei.

"We don't know what Bo Yuan said." Guan Yu sighed: "But our army is now small and few. If we can get the four counties and generals in Jingnan and reorganize the troops, it will take at least one year. If we want to attack Xiangyang again in a year, it will be just as Wei Yan said."

Then he looked out: "But this general, Bo Yuan, is quite knowledgeable."

"Wenchang really has a talented person, so it's a pity to be with me." Liu Yi nodded and glanced at Liu Bei.

Liu Bei smiled and said without saying anything, and said, "Boyuan doesn't have to worry about this matter. It's enough to get Jingnan and Jiangling, and Bei dare not ask for extravagance."

Liu Yi nodded and said nothing more. The four of them started to talk about other topics. At the current speed, it was still evening to arrive at the Cao army camp.
Chapter completed!
