"Husband, why is Ming'er like this?" In the middle of the night, Lu Lingqi leaned on Liu Yi's arms, a little worried about her daughter's performance during this time.

"With Cheng'er, you and I pay a lot less attention to her, and I'm worried that you and I don't love her anymore." Liu Yi found a more comfortable position to lean on the bed, which is also a bad thing for many bosses.

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

"Five-year-old, what do you want her to know?" Liu Yi scratched her nose, shook her head and smiled: "After April, I will leave for Jiangxia, pay more attention to the child's feelings, Cheng'er will hurt, and my daughter will also hurt, children, their minds are very sensitive and fragile." ”

Lu Lingqi understands the troubles of raising children at the moment, this is still Liu Yi's family is rich and can hire someone to help take care of the children, if this is placed in ordinary people's homes, how can they have so much energy to manage the children's mood, the boss is really going to make trouble, maybe he will kick it.

"Husband is leaving so soon?" Lu Lingqi was a little reluctant, it didn't seem to be long after this leisurely day, and Liu Yi was busy again.

"Well, Jiangxia's water village, the temples in various counties and some fortifications, at the end of the year, Xiangyang will also start to officially start construction, Cao Jun has seen us demolish Xiangyang in the past two months, and also knows that we are going to rebuild, and from time to time will send troops to attack and disturb, starting at the end of the year, I am afraid that I will sit there for a period of time." Speaking of this, Liu Yi was a little depressed, Jiangxia's fortifications were okay, and he could come back after hiring people.

But Xiangyang is different, this will be a city no less than Yueyang, unlike Yueyang, Xiangyang is going to face Cao Jun directly, so it has to be better in defense, but here's the problem.

Xiangyang does not have such abundant water resources as Yueyang City to use, and it is not difficult to build a strong city, but it is difficult to do it like Yueyang, let alone surpass it.

At least the crossbow arrows of the sixty-four broken crossbows in Yueyang City are chain structures, as long as the crossbow arrows are enough, they can theoretically continue to release arrows, and there are a large number of elevators and hydrodynamic catapults, if they are placed in Xiangyang, there is no way to do this.

And the further north you go, the more difficult it is to build a large hydrodynamic city like Yueyang City, and for the time being, Liu Yi can't find a natural energy source that can replace water power, he tried to make a steam engine when he was in Hanzhong, but although the principle of the steam engine is simple, it is not easy to make it.

The main requirement is the tightness, with today's forging level, even if it is him, it is a fool's dream to create a qualified cylinder purely by hand, and if the airtightness of the cylinder cannot meet the requirements, there is no way to conduct thermal energy into kinetic energy.

This time to design Xiangyang, Liu Yi couldn't help but bring up the problem of the steam engine again, just looking at the design drawings, in the end Liu Yi still sighed, he can make a miniature steam engine, but it can really be put into practical but there is no way, the cylinder is the primary problem that bothers him, even if it is barely made, the energy conversion process loss is amazing, maybe after he enters the seventh level, there will be a way to increase the technical level.

But Liu Yi himself is not sure, because this is not a matter of technical level, the technical level required for the steam engine is not high, but the requirements in terms of precision, which makes Liu Yi feel a little difficult to move an inch.

Hand-made steel plate, he can barely achieve mass production by the plug-in of the system, but the most difficult thing is the problem of welding, the mortise and tenon structure is not applicable to this, now what can be thought of is to do a preliminary job with the mortise and tenon structure, and then pour it with copper juice, but in this way, the airtightness can not be guaranteed!

It seems to have entered a dead loop, not that the ability is not good, but that the current smelting technology cannot meet the requirements, which cannot be solved in a short period of time, and even Liu Yi feels that even if his skill level reaches level seven and enters the state of that kind of skill is almost Dao, it is difficult to solve this problem.

Early the next morning, Liu Yi got up, first the model and drawings of the steam engine solemnly preserved, this span is too large, but it may not be possible to achieve it in his lifetime, whether it can let China enter the industrial age in advance is not easy to say, after all, this thing is the driving force of the industrial revolution, but it does not fully represent the industrial revolution, in history Britain has developed to the urgent need for a new power to replace human and animal power, the invention of the steam engine came into being.

However, the current China has not developed to that extent, there is no urgent need like that of Britain at that time, and when manpower and animal power are completely sufficient, even if the steam engine is built, it is difficult to quickly promote it without such a great sense of demand, and it will even be rejected and resisted.

Even if it's a seed for future generations.

Liu Yi shook his head with some regret, many things are not achieved overnight, the step is too big, you can only hurt yourself, in this era when culture is not popular, you really built a steam engine, maybe it will be regarded as witchcraft, but Liu Yi is really curious, if you build a steam engine yourself, what kind of attributes will it have?

Xiao Liu Ming's mood was a little low, holding Liu Yi's legs, refusing to let go, a five-year-old child, the most unbearable to part.

Liu Yi is also reluctant, but someone has to do things.

"Ming'er, don't mess around!" Lu Lingqi hugged Liu Cheng and couldn't let go of her hands, so she could only stare at Liu Ming unhappily.

"Well, wait for my father to come back next time and bring a lot of interesting things to Ming'er, how about it?" Liu Yi squatted down, touched Liu Ming's little brain and smiled.

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

What's going on with this inexplicable sadness?

Liu Yi was a little distressed, coaxing the child This kind of thing is really too troublesome, just looking at his daughter's aggrieved little face, and he couldn't bear to scold, so he could only persuade him with good words, and he finally persuaded his daughter to leave.

"At home, there is Mrs. Lao." Liu Yi breathed a sigh of relief slightly, and after gently hugging his wife, he smiled.

"Don't worry...... Come back early. Lu Lingqi nodded silently, and watched Liu Yi board the boat under the escort of the guards and look north along the lake.

……

Three days later, Xiakou.

"Tinghou, please take a look." In front of the huge sand table, Wen Ping held a few small flags, which were inserted on the sand table, corresponding to several positions downstream of Xiakou and said: "The last general is ready to set up three water villages in these three places, and set up several beacon towers between each other. ”

Liu Yi nodded, carefully calculated the actual distance of the three water villages that have not yet been built, as Wen Ping said, although the location of these three water villages is remote, but they are perfectly separated from each other by the waterway from Jiangdong to Jiangling.

The Yangtze River has a big bend in Jiangxia, and the water area is narrower than other places, and if the fleet in Jiangdong wants to come by water, it is easy to intercept it in Jiangxia, which is why Liu Bei Group must take Jiangxia back this time, not just to expand the territory.

"Just according to General Zhongye!" Liu Yi looked at the position on the sand table, and silently estimated in his heart, three water villages, each with a scale of 5,000 people, the upstream should also choose a site to build a shipyard, and four places that need to be started, the upstream water village is mainly for military training, and they can be replaced by each other in turn, and the scale and design of the water village have been outlined in his heart.

The next thing to do is to draw the drawings, and then hire workers to start building, the construction of the water village is not too ingenious at all, at most build a few water wheels, to provide some convenience for the water village, the organ part can be completed in about a month, and the rest do not need to be guarded by themselves.

"The wood, cement, bricks and tiles have been prepared, and the necessary coins have been transported over last month, I wonder when the pavilion will be able to start construction?" Wen Ping looked at Liu Yi and asked.

"Now." Liu Yi had already completed the estimation in his heart, looked at Wen Ping and said: "General Zhongye will go to gather people first, and we will start construction from this water village downstream." ”

"So fast?" Wen Ping looked at Liu Yi in surprise: "The last general has prepared a banquet for the pavilion marquis, it is better to rest for a day, and it is not too late to start construction tomorrow." ”

"You can eat the banquet at any time, and the water village here will be completed a day earlier, so you can be a little less worried." Liu Yi shook his head when he heard this, he didn't come to Jiangxia for a few meals, and there was a lot of work in the second half of the year, during the construction of the water village, he also had to go to the counties from time to time to preside over the erection of temples and bridges, the time schedule was very tight, and after the autumn harvest, he was going to Xiangyang to preside over the construction of the city, Xiangyang is still a big pit, Cao Jun came to harass it from time to time, Liu Yi had to fill in the pit as soon as possible.

Wen Ping smiled bitterly when he heard this, originally he was worried that Liu Yi was delaying and missing the construction period, but now it seems that he is too worried, he used to feel that Liu Yi was quite lazy, but now that he is doing things, this vigorous and resolute style has made Wen Ping have a new understanding of Liu Yi.

Although he is very lazy on weekdays, when he really starts to do things, the person in front of him has a rather resolute style, and he no longer persuades him at the moment, and after discussing the details with Liu Yi, Wen Ping went to recruit people.

According to the design, if the construction is the fastest, each construction site needs 500 people, and the water village can be built in about a month.

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

Liu Yi looked at the sand table, and took advantage of the time when Wen Ping went to recruit people, began to design drawings, and made a few models with some wood waste, so that when he was not there, the craftsmen used the models for reference.

The people were prepared a long time ago, and Wen Ping only ordered the craftsmen to assemble to facilitate Liu Yi to arrange the tasks, and it took a day for Liu Yi to assign the tasks of the three water villages, and hire the people, after completing these things, Liu Yi directly ordered Zhao Xu to start preparing the manpower and materials for temples and bridges in various counties, and this busy state lasted for a month.
