Funiu Mountain, Dahu Mountain, Shangjie Mountain, Zhongyang Mountain... The mountain village that was back then can no longer be found, but the roads I took back then are now compared one by one on the map, which makes people feel a lot of emotion, and it can be regarded as a revisiting place. This made Liu Yi couldn't help but think of the stupid donkey that changed his destiny.

Looking back at this moment, I was really reckless at that time. I dared to go on the road without any self-protection ability. Now I don’t dare to go out if I don’t have two or three hundred people around me~

I don’t know if I could be considered young and frivolous when I was in my twenties? Ten years have passed, and I feel that in addition to my mentality has become more and more vicissitudes, my appearance has not declined but increased. Lu Lingqi is so lucky.

"Marquis Ting! Going further east here is Baidu Mountain, which is adjacent to the river and flows eastward and can reach Runan!" The accompanying craftsmen came to Liu Yi and interrupted Liu Yi's nostalgic mood.

"Baidu Mountain..." Liu Yi compared the map and said, "Let's go and take a look."

Baidu Mountain is located where three mountains and four rivers gather, with lakes, water and mountains. It is a place with beautiful mountains and rivers. The terrain here can be built. If it is not too big, the power provided by the water will be enough. Moreover, the terrain here is surrounded by mountains and there are some mountain people who interpersonal relationships. If a village is considered a small town, and then a few beacon towers are built on the surrounding mountains, it can basically eliminate the opportunity for Cao's army to attack silently from here.

"Measure the rough geology here, the width of the river, the hydraulic power and the lateral distance of the open space, here..." Liu Yi roughly compared the scope and said: "Prepare to build a copycat and make the specific design as soon as possible."

Now Liu Yi’s Tiangongfang is not the same as the three or two kittens in the past. I don’t know how many famous craftsmen are willing to join Tiangongfang. They just want to get Liu Yi’s guidance. It is naturally the best to get Liu Yi’s magical skills. However, with more talents, Liu Yi classified these people, some were specifically responsible for design, and some were specifically responsible for various craftsmanship. With more people, Liu Yi no longer needed to do many things by himself. At most, he would process semi-finished products. For example, in terms of city design, the following craftsmen made a relatively comprehensive design. If there are more people, it is good to take into account all aspects. What Liu Yi needs to do is to optimize and improve these designs and then start to arrange the work.

No one will blame Liu Yi for making changes. There is no copyright statement these days. Besides, Liu Yi is not making changes by mistake. How many people can achieve this master level? I wonder how many people are asking for Liu Yi to change. This is the change brought about by reputation, status and ability.

"Here!" Several craftsmen agreed and began to arrange for people to measure.

As for Liu Yi, he sat on a bluestone, took the water bag handed over by Qin Wei and took a few sips. The weather was so hot.

"Marty Ting, the lord has led his troops to attack Wancheng. Most of the land in Nanyang has been obtained by our army." Liao Hua, the commander-in-chief in charge of Liu Yi's safety this time, came to Liu Yi and said.

"I know." Liu Yi nodded. After all, he was also the core figure around Liu Bei. How could Liu Yi not know the information ahead? He looked at Liao Hua and shook his head and smiled: "Even if you go back, there will be no chance of participating in the war. Cao Cao clearly has the intention to retreat, and now he is just a faceless person."

Liu Yi can guess some of Cao Cao's mentality now. After all, Nanyang is meaningless to Cao Cao now. In fact, Liu Bei occupied Nanyang. In addition to its strategic significance, he had to invest a lot of money to restore Nanyang. This place is a pit now. No matter who can do it, it will take a lot of manpower, material resources and time to operate it.

Cao Cao was even worse. The people in Nanyang were not very strong. This time he came to massacre the city directly, which was equivalent to handing over Nanyang to Liu Bei. In this case, if he fought to the death, the entire Cao Wei would not have to invest much energy in Nanyang. Now Xuchang has also moved to Yecheng by taking advantage of the last time the Imperial Physician Order. Cao Cao could retreat to Yingchuan to defend. If Liu Bei really fought, it would be difficult to move forward. After all, the lack of cavalry was the biggest problem when Liu Bei and Sun Quan faced Cao's army, and no one had any solution at the moment.

Therefore, Cao Cao's abandonment of Nanyang is the most correct choice now. Liu Bei was also afraid that Cao Cao would massacre again, so he pressed him step by step. Otherwise, if he delayed for another year or two, Cao Cao would definitely retreat by himself.

Liu Yi could see these things thoroughly, but Liao Hua couldn't accept them for a while: "Why did Ting Hou say that the battle is almost over?"

"Otherwise?" Liu Yi nodded naturally: "Logistics, food and grass are the key. Cao Cao can't hold on, and we can't hold on for too long."

"Ah?" Liao Hua looked at Liu Yi in shock. He remembered that after the construction of Xiangyang City, the grain was delivered in a truckload of cars, and the amount was quite large.

"A soldier has to eat six kilograms a day (258.24 grams per kilogram, 120 kilograms per kilogram). Now there are at least Liu Wan's army on the front line, and there are 3,000 kilograms of grain per day. There are also 100,000 kilograms of grain per month. How long do you think we can spend with Cao Cao?" Liu Yi looked at Liao Hua with a smile.

Liao Hua looked at Liu Yi ignorantly. If Liu Yi didn't say it, he knew that the consumption of marching and fighting was quite huge, but he had no idea about how big the method was. Now that Liu Yi calculated it like this, he understood.

"So, don't always think about fighting. No matter whether you win or lose, fighting is consumed. What we should think about is how to make some investments and be able to live a life." Liu Yi patted Liao Hua and said with a smile.

Now that Cao Cao retreated and Liu Bei took over the mess of Nanyang, that would be the best result. If both sides really fight to the death here, it would be good for each other. If the war between the two countries is involved, it would be a balance in mutual compromise. This is true with Sun Quan and Cao Cao. When Liu Bei is now, he should not have too many personal feelings.

However, there should be no need for Liu Yi to teach Liu Bei. After passing through the stage of the nouveau riche mentality in recent years, Liu Bei Group can now feel that the entire Liu Bei Group is beginning to develop in a more regular direction, and its mentality is slowly changing.

"Mr. Ting, you are so awesome!" Liao Hua said in admiration.

"This is actually not difficult." Liu Yi took out a book of the first volume of Tiangong's creation from his arms and handed it to Liao Hua and said: "I have learned this book, and it will be enough to do this. I'll give it to you."

As a general, Liao Hua can apply what he has learned and learn quickly.

"Thank you, Marquis Ting!" Liao Hua's face turned solemn, and he quickly took the book with both hands. This year, the gift of books was a great gift. Liao Hua himself came from the wealthy family in Miannan, and he knew the value of these things better than ordinary people.

"If you can't understand, you can ask me during this period." Liu Yi calmly accepted Liao Hua's gift. He could bear this gift, but the numbers in the book have not been popular yet. There are still many operation symbols. It is impossible for Liao Hua to understand it thoroughly.

"Here!" Liao Hua nodded.

...

As night fell, the battle in Wancheng gradually stopped with the arrival of night. The crisp sound of gold sound seemed a little pleasant in the smelly air. The Jingzhou army retreated like a tide. Cao Cao stood in the yamen office, feeling the loneliness after the hustle and bustle of fighting at this moment. The whole Wancheng fell into a dead silence, and felt that it was not as good as before.

Alas ~

"Lord!" Cheng Yu walked up and bowed to Cao Cao and said, "The emperor and all officials have moved to Yecheng. The current situation in Yecheng is so difficult for the prince to intimidate the ministers!"

"Zhongde also thinks, should we retreat?" Cao Cao looked at Cheng Yu and said with a smile.

"At present... it is indeed not appropriate to fight again. I am worried about chaos in the rear." Cheng Yu did not say what the situation in Nanyang was, but only talked about the problems in the rear. Now that Sun Quan captured Huainan, Cao Cao's voice will inevitably attract doubts. And this side did not gain an advantage in the battle with Liu Bei, and was even suppressed by the other side. If Cao Cao had not been in power for a long time, now he would be unable to take on important tasks with Cao Pi as the presidency.

It’s not that he lacks ability, but that he does not have enough prestige and cannot intimidate those old ministers. In fact, since he established Cao Pi as the crown prince, Cao Cao has consciously delegated power to Cao Pi, so that Cao Pi can stand alone, but it is obviously not possible at the moment. In Yecheng, Cao Cao still wants to go to the battlefield.

"It's a pity..." Cao Cao groped in the table with some nostalgia and sighed: "I don't know if I have a lifetime and I still have the chance to come back!"

"The lord, Chunqiu, will definitely be able to lead the king's army back!" Cheng Yu bowed and said.

"Prepare to withdraw your troops!" Cao Cao just smiled and said, "Let your son stay filial to Xuchang and see Liu Bei die for me! It can be considered as a meritorious service."

"Here!" Cheng Yu bowed silently.

After the decision was made, the next action of Cao's army was simple. The defenders of each county began to shrink rapidly. Cao Cao did not think that he could move the people of Nanyang in the current situation. He could only take away officials at all levels, Nanyang household registration and some important files. As for the food and supplies stored in each county, those who could be taken away, and those who could not be taken away, they would burn them directly.

As for the people of Nanyang, Cao Cao dared not kill him now, so he could only take advantage of Liu Bei.

In August of the 23rd year of Jian'an, the battle of Nanyang, which had been stalemate for more than a year, finally came to an end with Cao Cao's voluntary withdrawal of troops and giving up the land of Nanyang. However, what was left to Liu Bei was a broken Nanyang. The grain stored in the treasury was burned out. Because of the war, the land of Nanyang was almost completely harvested. During the period when Cao Cao withdrew his troops, countless refugees appeared in Nanyang and starved people everywhere.
