"Husband, why is this tomorrow?" In the middle of the night, Lu Lingqi leaned her body in Liu Yi's arms, and was a little worried about her daughter's performance during this period.

"With Cheng'er, you and I have paid much less attention to her. I am worried that you and I will not love her anymore." Liu Yi found a more comfortable position to lean on the bed, which was also a bad thing for many bosses.

"This kid is really ignorant." Lu Lingqi said helplessly.

"A five-year-old child, what do you want her to know?" Liu Yi scratched her nose and shook his head and smiled: "After April, I will set off for Jiangxia. Pay more attention to the child's feelings. Cheng'er will hurt, and his daughter will also hurt. The child is very sensitive and fragile."

Lu Lingqi now understood the trouble of raising a child. This is because Liu Yi's family is rich and can hire someone to help take care of the child. If this is placed in the home of ordinary people, how could he have so much energy to care for the child's mood? If the boss really wants to make trouble, he might kick him up.

"Husband is leaving so soon?" Lu Lingqi said reluctantly. It seemed that not long after this leisurely life, Liu Yi became busy again.

"Well, Jiangxia's water villages, and the temples in various counties have some fortifications. At the end of the year, Xiangyang will also start formal construction. Cao's army has come to see us demolish Xiangyang in the past two months and knows that we will rebuild and will send troops to harass us from time to time. From the end of the year, I'm afraid I'll be in charge there for a while." Speaking of this, Liu Yi was a little depressed. Jiangxia's fortifications were okay, and he could take a break after hiring people.

But Xiangyang is different. This will be a city no less than Yueyang. Unlike Yueyang, Xiangyang has to face Cao's army directly, so it needs to do better in defense, but here's the problem.

Xiangyang does not have as rich water resources as Yueyang City to use. It is not difficult to build a strong city, but it is difficult to achieve it like Yueyang, let alone surpass it.

At least the crossbows of the sixty-four Pojun crossbows in Yueyang City are chain structures. As long as the crossbows are sufficient, they can theoretically continue to shoot arrows. There are also a large number of lifts and hydropowered stone casting cars. If they are placed in Xiangyang, they will not be able to do this.

Moreover, the further north, it is more difficult to build a large hydropowered city like Yueyang City. At the moment, Liu Yi cannot find a natural energy source that can replace hydraulic power. He tried to make a steam engine when he was in Hanzhong, but the principle of the steam engine is simple, but it is not easy to make it.

It is mainly a requirement for airtightness. With the current forging level, even if it is his, it is simply a dream to create a qualified cylinder by hand. If the airtightness of the cylinder cannot meet the requirements, it will not be able to direct heat energy into kinetic energy.

This time when designing Xiangyang, Liu Yi couldn't help but raise the problem of the steam engine. Just looking at the design drawings, Liu Yi finally sighed. He was able to make a mini steam engine, but there was no way to really put it into practical use. The cylinder was the primary problem that bothered him. Even if it was barely done, the energy conversion process would be extremely lossy. Perhaps after he entered level 7, there would be a way to improve his technical level.

But Liu Yi himself is not sure, because this is not a question of technical level. The technical level required by the steam engine is not high, but the requirements for precision make Liu Yi feel that he is unable to move forward.

The hand-made steel plate can barely be mass-produced with the system plug-in, but the most difficult thing is the welding problem. The mortise and tenon structure is not suitable for this. What you can think of now is to water it with copper juice after the mortise and tenon structure is initially made, but in this way, the sealing cannot be guaranteed!

It seems that he has entered a vicious cycle. It is not that his ability is not good, but that the current smelting technology cannot meet the requirements. This cannot be solved in a short period of time. Liu Yi even feels that even if his skill level reaches level seven and enters a state where his skills are almost in the Tao, it will be difficult to solve this problem.

The next morning, Liu Yi stood up and solemnly preserved the model and drawings of the steam engine. This span is too large, but it may not be impossible to realize it in his lifetime. It is hard to say whether it can allow China to enter the industrial age ahead of time. After all, this thing is the driving force of the industrial revolution, but it cannot fully represent the industrial revolution. In history, Britain has developed to the point where it urgently needs a new driving force to replace human and animal power. The invention of the steam engine came into being.

But China has not developed to that level at the moment, and there is no urgent need like the UK at that time. When manpower and animal power are completely sufficient, even if the steam engine is built, it is difficult to promote it quickly without such a large sense of demand, and it will even be rejected and contradicted.

Even if it's a seed for future generations.

Liu Yi shook his head with some regret. Many things were not achieved overnight. Taking too much steps would only hurt himself. In this era when culture was not popular, he really made a steam engine and might be regarded as a witchcraft. However, Liu Yi was really curious. If he built a steam engine himself, what attributes would it have?

Little Liu Ming was a little depressed. He hugged Liu Yi's legs and refused to let go. The five-year-old child could not bear the pain of parting.

Liu Yi was reluctant to give up, but someone had to do it.

"Tomorrow, don't make trouble!" Lu Lingqi hugged Liu Cheng, unable to let go, and could only stare at Liu Ming and said unhappy.

"Be good, wait until my father comes back next time, and bring a lot of fun things to me tomorrow, how about?" Liu Yi squatted down and touched Liu Ming's little head and smiled.

"No, I want dad." Liu Ming shook his head.

What's going on with this inexplicable sadness?

Liu Yi was a little distressed. It was really troublesome to coax the child. He just looked at his daughter's aggrieved face and couldn't bear to scold him. He could only persuade him with kind words. He was useless to persuade his daughter to finally persuade him to leave.

"There is Madam Lau at home." Liu Yi breathed a sigh of relief, hugged his wife gently, and smiled.

"Don't worry, husband... come back early." Lu Lingqi nodded silently, watching Liu Yi board the boat under the escort of the guards, and head north along the lake.

...

Three days later, Xiakou.

"Please look at the marquis of Ting." In front of the huge sand table, Wen Pin held several small flags and inserted them on the sand table, corresponding to several locations downstream of Xiakou: "I will prepare to set up three water camps here at the end, and set up several beacon towers between each other. If there is really any abnormal movement in Jiangdong, our army can be prepared in the shortest time."

Liu Yi nodded and carefully calculated the actual distance between these three water villages that have not yet been built. As Wen Pin said, although the locations of these three water villages were chosen remotely, they perfectly separated the water routes from Jiangdong to Jiangling from each other. If there is really a sudden movement in Jiangdong, it will be extremely easy for the three water villages to clamp down or cut off their retreat routes.

The Yangtze River has a big bend in this section of Jiangxia, and the waters are narrower than other places. If the fleet in Jiangdong wants to pass by, it is easy to block it in Jiangxia. This is also the reason why Liu Bei Group must take back Jiangxia this time, but it is not just to expand the territory.

"As General Zhongye said!" Liu Yi looked at the location on the sand table and silently estimated in his mind that there were three water camps, each mainly in the scale of 5,000 people. The upstream also had to choose a location to build a shipyard, and there were places where construction needed to start. The upstream water camps were mainly trained and could be replaced in turn. The scale and design of the water camps had already made outlines in his mind.

The next thing to do is to draw out the drawings and hire workers to start building. The construction of the water village is not too clever. At most, a few water trucks can be built to provide some convenience to the water village. The agency can be completed in about a month, and the rest does not need to be kept by yourself.

"The wood, cement, and bricks are ready. Last month, I have transported the required coins. I wonder when will the Hou Ting start construction?" Wen Pin looked at Liu Yi and asked.

"Now." Liu Yi had already completed his estimate in his heart, and looked at Wen Pin and said, "General Zhongye will gather people first, and we will start construction from this downstream water camp."

"So fast?" Wen Pin looked at Liu Yi in surprise: "The last party has prepared a banquet for the Marquis of Ting. It's better to take a day off and start construction tomorrow."

"You can eat any time for a banquet. The water village here can be completed one day earlier, so you can be less worried." Liu Yi shook his head when he heard this. He did not come to Jiangxia for a few meals. Besides, the project volume in the second half of the year is quite large. During the construction of the water village, he would have to go to various counties to preside over the temples from time to time. The bridge was laid out in a very compact time. After the autumn harvest, he would go to Xiangyang to preside over the construction of the city. Xiangyang is still a big pit now. Cao's army comes to harass him from time to time. Liu Yi has to fill the pit as soon as possible.

Wen Pin smiled bitterly when he heard this. He was worried that Liu Yi would delay and miss the construction period. Now it seems that he is too worried. He used to think that Liu Yi was quite lazy, but now when doing things, his decisive style has given Wen Pin a new understanding of Liu Yi.

Although he is lazy on weekdays, when he is really doing things, the person in front of him has a very decisive style. He no longer persuades him now. After discussing the details with Liu Yi, Wenpin went to recruit people.

According to the design, if the construction is fastest, each construction site requires 500 people, and the water village can be built in about one month. Liu Yi chose a fast ship and inspected it back and forth to solve some mechanism problems that craftsmen could not handle.

When you have nothing to do, you can go to various counties to build temples.

Liu Yi looked at the sand table and took advantage of the time when Wenpin was recruiting people, he began to design drawings and made several models with some wood waste to facilitate the craftsmen to use models to refer to when he was away.

The civil servants had prepared a long time ago, and Wenpin only ordered the craftsmen to gather to facilitate Liu Yi to assign tasks. After spending a day, Liu Yi assigned the tasks of the three water villages and hired civil servants. After completing these things, Liu Yi directly ordered Zhao Xu to start preparing resume temples, bridges and supplies in each county. This busy state lasted for a month.
Chapter completed!
