"Boyuan's methods are really magical." After a moment, Liu Bei stood on the enemy's building. If he climbed up such a high city wall, it would probably take at least half a quarter of an hour, but now it only takes a cup of tea to get up.

"Hey, brother, I'm afraid I don't know that Bo Yuan has installed such cloud rooms in our mansions, but it's not that big." Zhang Fei grinned. The cloud rooms he and Zhang Bao and his son played with were almost broken in the past few days.

"Actually, the principle is not difficult." Liu Yi shook his head and said, "Just like we used hanging baskets to transport things from the city, but now we are not using manpower, but using the power of Dongting Lake."

"What are the water dragons I saw outside the city?" Guan Yu said strangely.

"That is, those water dragons are the power hubs in the entire city." Liu Yi smiled and said to Guan Yu: "I studied these eight water dragons for a long time in order to choose to place these eight water dragons."

Liu Bei held the female wall with his hand, and suddenly felt something was wrong. He touched the female wall and looked at Liu Yi and said, "Boyuan, is this what you call cement?"

Liu Yi nodded and said, "This city wall or the entire city is built with cement and bricks. The lord doesn't have to worry about its strength. Generally, the stone generator is difficult to shake. However, in order to avoid collapse and cracks, the city wall is solid, not like Mocheng, but it is not a hollow city wall. It is difficult to cause damage to the city wall if it is a large siege vehicle."

Liu Bei groped through the female wall, turned his head and waved to a personal guard. He took a ring-headed knife from his personal guard and cut down on the female wall, but only a white blade was left. The knife was produced by Tiangongfang before, and was sharp and strong. He had an advantage in fighting against Cao's army. Generally, Liu Bei could cut down the city wall with such a knife, at least he could cut a gap, but now he only left a white mark.

"It's indeed a strong city!" Liu Bei returned the sword to his personal guard and groped for the female wall. Not to mention anything else, the solidity of the city wall and the height of the city wall, and ordinary siege equipment cannot reach the edge of the city wall. It is even more impossible to attack the city gate. They have seen the power of the city gate before. Not only is it automatic, but the thickness of the city gate alone, it may not be able to push it.

Several people walked out of the enemy building and walked along the city wall, but they saw that the city wall was extremely wide, just as wide as it was five meters wide. Even if they lined up here, they were not crowded at all. Moreover, there was a high platform every few meters above the city wall, about two meters high. Standing on it, the enemy's arrows might not be able to shoot up, and there was also a floating bridge between them, which was also a kind of blocking, blocking the rain of arrows for the soldiers below.

"Boyuan, what is this?" Zhuge Liang stood beside a corner tower, looking at a huge creature above the corner tower. There was a huge tree at the front, but there were rows of holes above the giant tree, and there was a faint cold light inside. It was obviously a kind of city guarding equipment. But with Zhuge Liang's knowledge, he had never even heard of it.

"Pojun Crossbow!" Liu Yi smiled and said, "This crossbow has thirty-six holes, which can shoot thirty-six crossbow arrows at a time, and is equipped with a crossbow box. After it is shot, it can be replaced quickly and continued shooting. The city wall is in the shape of Bagua, which means there are eight walls, and each side is equipped with nine broken formation angers, which is exactly the number of Tiangang and Earth Demons. If there is really a large army attack, these broken formation angers alone can cause heavy losses to the enemy and greatly save manpower."

"If you defend the city in an ordinary way, the city needs at least 20,000 people to defend it, but if this thing is there, ten thousand soldiers and soldiers can cooperate with some civilians to control these mechanisms and equipment to protect the city." Zhang Fei smiled proudly.

He had tried the power of breaking the formation and anger himself, and it was really a powerful weapon to defend the city.

"This city wall not only has a rage to break the formation, but also a stone generator, and a hanging bucket specially used to transport wooden and stones to raise the loading of wood and stones. It is very convenient to carry materials. If there is enough manpower to operate these mechanisms, it is only a defense of the city, six thousand people will be enough." Liu Yi shook his head and smiled.

"Oh, it's a pity that the population in this city is only more than 10,000, and the soldiers are only 2,000." Zhang Fei said with some regret: "It's still Cuizhouping moved the county seat here and brought the county soldiers here, otherwise there would be even fewer."

Liu Bei nodded silently when he heard this. This new city is indeed very good. The city wall alone is like an iron barrel. But as Zhang Fei said, no matter how good the city is, it must be guarded by people. Where can so many people come from to supplement the city now?

Moreover, Liu Bei's current purpose is very clear. It is Yizhou, and the public security is the best location, and it is impossible to move the capital here.

Guan Yu frowned and looked at Liu Yi and said, "Does Bo Yuan want to move people from Nanjun?"

"No need!" Liu Yi shook his head and said, "If you have nothing to do, I have ordered my wife to prepare a family dinner at home. I wonder if the lord and you are willing to move? Yi was also about to discuss this matter with the lord and Kong Ming and Shiyuan."

Liu Bei nodded when he heard this. Although the city was quite majestic and strong, he felt a little bored when he thought it could not be used. However, Liu Yi obviously had other ideas. He nodded and took everyone away from the city wall in the cloud room. Under Liu Yi's leadership, he went to his own manor.

"This manor..." Zhuge Liang looked around and smiled: "Boyuan was also built with the Bagua Formation?"

"Not." Zhang Fei smiled and said, "If someone who doesn't know how to write the military formation comes in, it will not be easy to get in."

"Actually, there is no such trouble." Liu Yi pointed to the ground and said, "Follow the bluestone road, you can go directly to the main hall. If it is paved with fine sand, it leads to the Martial Arts Court. If it is paved with wooden boards, you can go directly to the hiding. If it is paved with gravel road, you can go to the back garden."

Everyone looked around and saw that although the road was messy, the materials were different.

Zhang Fei: "..."

No wonder my wife clearly doesn't understand the military formation, but she has never lost her way. She is still proud of this every day. Now that I think about it, I am really embarrassed. She glared at Liu Yi fiercely, and Zhang Fei silently shut up and decided not to pay attention to him.

"I have met the emperor's uncle, the head of the family, the military advisor and the generals." Deng was greeted by everyone, and said to Liu Bei with a smile: "Mrs. Mi, Mrs. Guan, Mrs. Xiahou and Mrs. Huang are already in the back hall, and the wife is entertained by the wife. The things that the head of the family has already prepared are ready."

"I'm working hard for my sister-in-law." Liu Yi nodded with a smile: "Lord, the journey is exhausting. I happened to have some fresh ways to eat it recently, and it's just a banquet for you."

"Boyuan is intent." Liu Bei smiled and nodded. The group went straight into the main hall, took the cloud room, and went to the third floor. There was Liu Yi's banquet hall. The hall was not big, and the windows on all sides were opened. Shelves were placed everywhere. The burning carbon stone inside had no flames. A maid was grilling a bunch of meat skewers with bamboo sticks on the grill, smearing some condiments from time to time. As soon as everyone came in, the scent of the smell of the meat was already filled. Even though they were not much hungry before, they couldn't help swallowing their saliva secretly when they smelled the aroma of the meat.

"Boyuan, is this barbecue?" Zhang Fei came to a grill, looked at the fragrant skewers, looked at Liu Yi, and had long thrown his determination to ignore Liu Yi.

"That's right, I made some improvements." Liu Yi nodded. Barbecue is not a new invention. It's just that the mainstream way to eat it in this era is to cook. Barbecue can be applied with some salt at most. The taste is actually good, but it is not good. Liu Yi specially collected the seasonings that can be found now and tried it. Although there is no cumin, it is much more delicious than barbecue with only salt.

The most important thing is that the grill is made by yourself, which naturally has the effect of increasing the taste of the food. At least Liu Yi tastes no worse than in his previous life. Of course, it would be even better if he could have some cumin.

"Please." Liu Yi reached out to Liu Bei and welcomed Liu Bei into the main seat. Then he asked everyone to sit down and asked someone to bring the drinks.

This banquet was considered a private banquet, and they were all acquaintances, so they were quite comfortable and didn't have so many social engagements.

"Boyuan, you haven't told the reason yet." Although he was eating happily, Liu Bei did not forget the main business and asked Liu Yi.

"I'm also making the worst plan!" Liu Yi nodded, and ordered someone to carry the sand table he prepared over.

The exquisite sand table lit up the eyes of everyone present.

"I have previously traveled all counties and made this sand table. Please see, lord." Liu Yi pointed to the map and said, "This is a new city. Not only is it on the shore of Dongting Lake, but it is connected to both water and land. In the future, the lord attacks Yizhou. Once Jiangdong attacks, he must first take Changsha. Once Jiangdong sends troops, it must have been planned for a long time. With Changsha's troops, it may be difficult to resist. However, if they want to capture the four counties in Jingnan, this new city will become the throat. Judging from the transportation route of food, grass and supplies in the future, no matter what, they cannot avoid the new city. With this city blocking, as long as this city is not broken, Jiangdong will be unable to move forward!"

Guan Yu looked at the sand table and frowned and said, "Why is Bo Yuan so sure that Jiangdong will come to attack?"

"If the lord cannot take Yizhou, Jiangdong may not dare to rebel against the lord, but if the lord takes Yizhou, he will also be in the two states. The strength will be reversed by then. If I am Sun Quan, if I cannot take Jingzhou, then Sun Quan is the weakest among the three families of Cao Cao, Sun Quan and the lord. Sun Quan is quite talented, how can he be willing to watch his lord come from behind?" Liu Yi looked at Guan Yu and said seriously: "Of course, this is the worst plan. The best result is to make a good Sun Quan and fight Cao Cao together. It is also the worst plan. It may not be really used. Quan is prepared for any event. Once Jingnan is taken away, the lord will be in Yizhou at that time, and the land of Nanjun is alone and difficult to roar. It is even sandwiched between Cao Cao and Sun Quan, so Jingzhou will be difficult to protect!"

Liu Bei looked at the sand table with a complicated look. In fact, even now, there has been a bit dirty between him and Jiangdong. However, Lu Su is now the commander-in-chief of Jiangdong and insists on joining forces with Liu to fight against Cao, but within Jiangdong, the voice of trying to destroy Liu Bei has never stopped.
