Funiu Mountain, Dahu Mountain, Shangjie Mountain, Zhongyang Mountain...... The cottage of the year, coming back now, can no longer be found, but the road traveled back then is now compared on the map one by one, but it is quite emotional, and it can be regarded as a revisit, which makes Liu Yi can't help but think of the stupid donkey who changed his fate.

At this moment, thinking back to ten years ago, it was really reckless at that time, this kind of time dared to go on the road without any self-protection ability, and now there are no two or three hundred people around who dare not go out~

I don't know if I can still be regarded as young and frivolous when I was in my twenties? Having said that ten years have passed, I feel that in addition to the vicissitudes of mentality, this appearance has not decreased but risen, Lu Lingqi is really blessed.

"Tinghou! Here further east, is the Baidu Mountain, adjacent to the water, down the river to the east, can go straight to Runan! The accompanying craftsman came to Liu Yi's side, interrupting Liu Yi's nostalgic mood.

"Baidu Mountain......" Liu Yi checked the map and said: "Let's go, go over and have a look." ”

Baidu Mountain is located in the place where three mountains and four rivers converge, there are lakes and rivers and mountains, it is a place where the mountains and rivers are beautiful, the terrain here can build a water village, not too big, the power provided by the water is enough to supply, and the terrain here, surrounded by mountains, there are some mountain people in the interpersonal relationship, if a village is a small town, and then build a few beacon towers on the surrounding mountains, it can basically prevent the opportunity for Cao Jun to want to attack silently from here.

"Measure the general geology here, as well as the width of the river, the hydraulic power and the lateral distance of the clearing, here ......," Liu Yi roughly compared the scope and said, "I am going to build a cottage and make the specific design as soon as possible." ”

Now Liu Yi's Tiangongfang is not the kitten three or two in the past, I don't know how many famous craftsmen are willing to join the Tiangongfang, just to get Liu Yi's guidance, to be able to get Liu Yi's magical ability is naturally the best, there are many talents, Liu Yi will classify these people, there are specifically responsible for design, there are also responsible for various processes, there are many people, many things in fact, Liu Yi no longer needs to do it himself, at most is to process the semi-finished products, such as the design of the walled city, The craftsmen below made a more comprehensive design, the number of people is good in this aspect, and all aspects can be taken into account, and what Liu Yi has to do is to optimize and improve these designs, and then start to arrange the work.

No one will blame Liu Yi for altering, there is no copyright in these years, and Liu Yi is not blindly changing, the level of master, how many people can reach it in the ground? I don't know how many people are begging Liu Yi to change, this is the change brought about by fame, status and ability.

"Whoa!" Several craftsmen said yes and began to arrange for people to measure.

As for Liu Yi, he sat on a piece of bluestone, took the water bladder handed by Qin Wei and drank a few sips, the weather was hot.

"Tinghou, the lord has waved his troops to attack the city of Wancheng, and most of the land of Nanyang has been obtained by our army." Liao Hua was the commander in charge of Liu Yi's security this time, and he came to Liu Yi's side at this moment.

"I know." Liu Yi nodded, how to say that he is also the core figure around Liu Bei, how could Liu Yi not know the intelligence in front of him, glanced at Liao Hua and shook his head and smiled: "Now that you go back, there is not much chance to participate in the war, then Cao Cao has clearly retreated, and now he just can't pull his face." ”

Cao Cao's mentality, Liu Yi can guess some now, after all, Nanyang is a place, for today's Cao Cao, it really has no meaning, in fact, Liu Bei occupies Nanyang, in addition to the strategic significance, if you want to restore Nanyang, you have to invest a lot of money, this is a pit now, no matter who gets it, it takes a lot of manpower, material resources and time to operate.

Cao Cao is even worse, the hearts of the people of Nanyang are not high, this time directly came to slaughter the city, which is equivalent to giving Nanyang to Liu Bei, in this case, if it is dead, the whole Cao Wei does not know how much energy to invest in this place in Nanyang, and now Xuchang has also moved to Yecheng by taking advantage of the last time the Taiyi ordered those people, Cao Cao can completely retreat to Yingchuan to defend, if Liu Bei really fights, it will be difficult to move an inch, after all, the lack of cavalry is the biggest problem for Liu Bei and Sun Quan in the face of Cao's army, and no one has a solution at the moment.

Therefore, now Cao Cao's abandonment of Nanyang is the most correct choice, and Liu Bei is also afraid that Cao Cao will slaughter the city again, so he is pressing step by step, otherwise, if it drags on for another year and a half, Cao Cao will definitely retreat by himself.

Liu Yi saw these things clearly, but Liao Hua couldn't accept them for a while: "Tinghou is saying that the battle is almost over?" ”

"Or else?" Liu Yi nodded as a matter of course: "Logistics, grain and grass are the key, Cao Cao can't support it, and we can't last too long." ”

"Huh?" Liao Hua looked at Liu Yi in amazement, he remembered that after the completion of Xiangyang City, the grain was sent in truckloads, and there were a lot of them.

"A soldier has to eat six catties a day (258.24 grams per catty in Han, one hundred and twenty catties per stone), there is at least Liu Wan's army on the front line now, three thousand stone of grain a day, and the people who transport it back and forth eat every day, and one hundred thousand stone of grain and grass in a 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 what kind of huge law, he had never had a concept, and now that Liu Yi counted it like this, he understood.

"So, don't keep thinking about fighting, whether you win or lose, fighting is attrition, what we should think about is how to make some progress and be able to live." Liu Yi patted Liao Hua and smiled.

Now that Cao Cao is retreating, Liu Bei takes over the mess of Nanyang, that is the best result, if the two sides are really dead here, it is not good for anyone, when it comes to the war between the two countries, it is to form a balance in mutual compromise, and Sun Quan is like this, and Cao Cao is actually the same, to the point where Liu Bei is now, in fact, there should not be too many personal feelings.

However, these things should not need Liu Yi to teach Liu Bei, Liu Bei Group has gone through the stage of the nouveau riche mentality in the past few years, and now it can actually feel that the entire Liu Bei Group is beginning to develop in a more formalized direction, and the mentality is slowly changing.

"Tinghou, you are really powerful!" Liao Hua admired.

"It's not that hard." Liu Yi took out the first volume of Tiangong Kaiwu from his arms and handed it to Liao Huadao: "This book has been learned, and it is almost enough to do this, I will give it to you." ”

The basic addition, subtraction, multiplication and division operations, Liao Hua, as a general, can better apply what he has learned, and he will learn it quickly.

"Thank you, Tinghou!" Liao Hua's face was solemn, and he hurriedly took the book with both hands, this year, giving books is a big gift, Liao Hua himself is from the wealthy family of Cannan, for these things, he knows the value of them better than ordinary people.

"If you don't understand, you can ask me during this time." Liu Yi calmly accepted Liao Hua's gift, he can afford this gift, but the numbers in the book have not yet been popularized, and there are so many operation symbols, it is impossible for Liao Hua to eat it thoroughly.

"Whoa!" Liao Hua nodded.

……

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

Alas~

"Lord!" Cheng Yu walked up, bowed to Cao Cao and said: "The Son of Heaven and the hundred officials have moved to Yecheng, and the current situation in Yecheng is difficult for the prince to deter the ministers!" ”

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

"Right now...... It is indeed not advisable to fight again, and the minister is worried about chaos in the rear. Cheng Yu didn't say what the situation in Nanyang was, just said that the problem in the rear, now that Sun Quan has captured Huainan, Cao Cao's momentum will inevitably attract doubts, and this side has not been able to gain an advantage in the battle with Liu Bei, and even pressed by the other party.

It's not that the ability is insufficient, but the prestige is not enough, and it can't deter those old ministers, in fact, since the establishment of Cao Pi as the prince, Cao Cao has consciously delegated power to Cao Pi, so that Cao Pi can be on his own, but at the moment, it is obviously not possible, Yecheng side, or Cao Cao still wants to go to the town.

"It's a pity that ......" Cao Cao groped around the table with some nostalgia, and sighed: "I don't know if there is a chance to come back in my lonely life!" ”

"The lord is in the prime of spring and autumn, and he will definitely be able to lead the king to kill it back!" Cheng Yu bowed.

"Prepare to withdraw your troops!" Cao Cao just smiled and said, "Let Zi Xiao guard Xuchang, and show me Liu Bei to death!" It can be regarded as a meritorious service. ”

"Whoa!" Cheng Yu bowed silently.

After having a decision, Cao Jun's next action was simple, the defenders of the counties began to shrink rapidly, Cao Cao did not think that in the current situation, the people of Nanyang could be moved, and he could only take away officials at all levels, Nanyang household registration and some important files.

As for the people of Nanyang, Cao Cao didn't dare to kill indiscriminately now, so he could only cheap Liu Bei.

In the twenty-third year of Jian'an, in August, the battle of Nanyang, which had been stalemate for more than a year, finally ended with Cao Cao's initiative to withdraw the army and give up the land of Nanyang, but what was left to Liu Bei was a dilapidated Nanyang, and the grain in the treasury was burned out.

When Liu Bei saw this situation, he could only give up the pursuit of Cao Cao, and began to order people to transfer all the grain stocks in Xiangyang to help the victims and reorganize Nanyang, even Liu Yi was recalled by Liu Bei, first to give Jinan to Jinyang, and then to say that the rest of the three months in the twenty-third year of Jian'an, almost the entire Jingzhou was running around this matter.
