On the top of the mountain in March, the wind is very strong, and in the evening, the mountain wind is like a knife, and the chill is biting.

The craftsmen huddled together in the stilt-built sheds, slept on wooden straw sheets, covered with quilts, and dealt with them simply.

Compared with the humble sheds, a few wooden houses are undoubtedly "tall". There was a dim light in the paper window, and at the desk by the window, a few people were studying the drawings, and from time to time they would look through the booklets.

"When the load of the hydraulic station increases and the flow required by the turbine increases, the reservoir in the front room can be used to supplement the insufficient water from the channel, so as to avoid the water level dropping and causing air to be drawn into the pressure water pipe to reduce the output of the turbine; On the contrary, when the load is reduced or too much water from the upstream causes flooding, it can be discharged through the overflow channel so as not to affect the safety of the building...... Wonderful, wonderful......"

Du Mingzhong, who was lying in front of the case, couldn't help but admire the exquisite design of the "hydraulic station" again.

"It's not exquisite, you look at this water box again, although it looks like a wooden gate, but this wooden gate is not another wooden gate, you see, its structure is an arc gate, it needs to use a pulley block and a hand-cranked wooden winch when it opens, close by gravity moment, the structure is simple, the opening and closing is fast, and the use is far better than the old wooden lock, in my opinion, the lock on the canal can be completely replaced by this lock."

Zhao Fengqian almost subconsciously thought of the canal locks, after all, because of the topography, the Qianli Grand Canal itself has many locks, and those locks are clumsy old-style locks, and the "locks" of the "hydraulic station" have the potential to be used as locks, of course, they need to be further improved.

"Hey, I said Ye Mao, don't be delusional, what is the appearance of the court's nervousness now, and change the lock, there is so much silver."

"Not now, there will always be ...... in the future"

Looking at the boat, no, it should be the blueprint of the "sluice", Zhao Fengqian couldn't help but sigh.

"You say that the prince brought these wonderful works from there, even this paper ......"

Picking up the paper on the table, Zhao Fengqian couldn't help but shake his head.

"The color is as white as snow, crisp as a page, although this kind of paper is not suitable for calligraphy and painting, but it is ......"

"It's not suitable for calligraphy and painting with a brush, it's better to use a pencil."

Shaking the pencil in his hand, Li Chengkun smiled.

"It's perfect for a pencil with paper like this."

"The pencil, that's what the prince also brought."

"And these brass rulers, compasses ......"

"And ......"

Pointing to the things on the table, everyone couldn't help but be stunned, the things on the table were all unheard of and unseen by them, but they were all brought by the prince.

"This, these things, shouldn't it really be that the prince of the world brought them from the Heavenly Palace!"

casually said it, but everyone was dumbfounded, and they even picked up the copper ruler on the table, looked at the beautifully carved and standard scale, and were speechless for a long time. They knew that at the beginning, Zhu Guoqiang bought a plastic ruler and a steel ruler, and later thought that the plastic ruler, and even the steel ruler were too "amazing", so they bought a more expensive brass measuring tool, but even so, still

After a long time, someone said it as if it were a joke.

"Don't you see, there are even people selling red bricks in the bazaar, and some people buy them and bring them back to worship, saying that they have the immortal aura of the prince on it, but in fact, it ......."

"Actually, there are so many sayings, just like this hydraulic station, the world says that the prince is the god of fire, but this is water."

"But, these things ......"

"It was given to us by the prince, we just need to learn and use it well, don't you say?"

"What Brother Renqin said is very true, and what he said is very ......"

Despite saying this, there are inevitably some doubts hidden in the hearts of these people, and in the end, all doubts will be attributed to two words - Heavenly Palace.

Even Zhu Guoqiang himself didn't know that the reason why outsiders did not suspect the things he took out from time to time was precisely because of the identity of the so-called "Huo De Zhenjun" who went down to earth, because the big guy was willing to believe in the existence of the Heavenly Palace.

In the next half month, hundreds of craftsmen worked day and night for the "hydraulic station", but the construction process was not as smooth as imagined, because the supervisor did not understand the drawings, it was inevitable that he would not notice some details, resulting in repeated rework, wasting a lot of materials, not to mention, also wasting a lot of time, but even so, whether it was the craftsmen who participated in the construction, or the apprentices who were responsible for supervising the work have gained a lot of experience to the maximum.

And the accumulation of this experience, to a certain extent, even more important than the hydroelectric station itself, after all, for the world, the "hydroelectric station" born from the hydropower station is undoubtedly the world's first leading era of "industrial products", even if the "soil law on the horse", it is far beyond the world's technical level, to be able to complete it, and put into use, itself is a miracle.

Even without waiting for Zhu Guoqiang to customize the water turbine from the other side, the carpenters in this world made the water turbine out of hardwood according to the drawings he provided, and even together with the pressure water pipe, it was also spliced with wood, and then tightened with iron hoops, which was completely built according to the standard of "soil and hydropower".

In fact, the reason why the project can be carried out extremely smoothly is that the "soil and hydropower" aimed at providing electricity to the rural areas not only has detailed drawings, but also has detailed and simple explanations; during the special period, it is not a group of engineers who participate in the construction of the "earth and hydropower", but a group of illiterate and semi-literate peasants, at most a few middle school students participate in the supervision, and occasionally one or two technicians from the county will guide them for a day or two. And now, students like Du Mingzhong and others play the role of middle school students, and Zhu Guoqiang is "a technician from the county".

As for the craftsmen who are the peasants, under their guidance they excavate earthworks, ditches, and build factories, these are all things that they are familiar with, after all, water ditches are ditches, and the rest is just masonry to build houses.

After almost a month of busy work, the "hydraulic station", which symbolizes "industrial civilization", finally stands at the foot of Wufeng Mountain.

With a shout of "water is coming", the water flows down the ditch into the front pool and then into the hydraulic station through a wooden pressure pipe.

"Moved, moved......"

The turbine turned, not as fast as it was, but far more than an ordinary waterwheel. When the onlookers watched it spin, they all turned their eyes to the prince, and then?

What's next?

"Plug in the drivebelt!"
