I do research in ancient times

Spring plowing is a big deal.

Even though the military farmland in Yongxiguan has completed sowing, subsequent topdressing and interplanting can still make up for it.

The curriculum of the first agricultural science class mainly revolved around fertilizers and intercropping, and specially designed fertilization schemes for the crops planted in military fields. The learning tasks were not trivial.

Fortunately, the soldiers in the army are extremely rare this opportunity to enter the school.Regardless of whether you are smart or not, you are serious in class.Those who are slow learners are unwilling to lag behind. They stay up late to review for several nights. If they have time, they find their companions to explain the knowledge points. Keep up with the progress.

One month later, all the first batch of agricultural students passed the final exam.

As a few years after graduation, they were invited to visit Jiuling City, which is still under construction, and have a spring outing by the way.

When the news reached the agricultural science class, the reaction of the military officers was not very enthusiastic.

During this period of time, they have seen too many new gadgets in Mozongwu Castle, and their nerves are getting stronger day by day. They are no longer the "bumps" when they first entered Wubao.

I thought there would be a surprise on the last day, but when I heard that I was going to Jiuling Lake, everyone was somewhat disappointed.

They're about to leave, don't you really think about making another meal of braised pork to see them off?

"Jiuling Lake? Isn't that just a big bubble! My hometown used to be not far away, and I used to touch fish when I was a child!"

A young soldier said.

Jiuling Lake is not far from Yongxiguan, just at the northern foot of Niubei Mountain.This group of military camps are all from nearby towns, and they are no strangers to Jiuling Lake.

"There's nothing in that place except water! There's a river that leads to the Wuzhi River, so it's meaningless."

Hearing what he said, the other middle-aged Juntun sighed with a gloomy expression.

"My hometown used to be by the Wuzhi River. There used to be a barbarian tribe along the river to the north. They were very friendly. They could exchange rice and salt for delicious mutton. They also loved the gadgets here. like very much."

"Later, that tribe moved away because of the human riots. My hometown was also robbed, and half of the village was killed. Those humans are all livestock!"

"If it wasn't for most of the escort soldiers taking back the east road at that time, we would all be trapped to death in the mountains."

Hearing him talk about the old things made everyone feel even more depressed.

In the end, it was Lao Juntun who knocked on the cigarette bag.

"It's different now. Mo Zong has reclaimed new fields over there, and it is said that he will build a dam on the Wuzhi River. You can gain a lot of experience by going there."

"I've seen the water dragon they use for irrigation before, but it's a magical mechanism. It can lift water by stepping on it, without any effort."

"At that time, the teacher said that if the dam is built in the future, the water dragon can move by itself, which is more physiological than it is now."

The old army is still very prestigious in the agricultural science class. He has said so, and the rest of the people also have some expectations for Jiuling Lake.

But when people arrive at Jiuling Lake... Jun Tuenmen's eyes are straightened.

"elder brother……"

The young Juntun was dumbfounded, and mechanically tugged at the middle-aged man beside him.

"Brother, was your village like this before? This, this, this, this is too... ah!"

He thought for a long time and didn't know what words to use to describe it. The land in front of him could no longer be called a "village" in his cognition. It was clearly a city!

No, no!

The young Juntun scratched his head.

It can't be said that it is still a city, at least it is different from any town I have seen!

Take Ding'an City as an example, it is the most prosperous town in northern Xinjiang, with high walls, large and small squares, and houses and shops along the street. .

Not only Ding'an City, but also other small cities in the frontier fortress, the only difference is in size and population.

But Jiuling Lake is completely different.

The houses here are built in different shapes according to the area, but most of them are plastered with gray cement, and the color style is very uniform.For example, the place where they are standing now is a square two-story building, with stairs and railings installed along the walls, and independent doors every few meters.

It's just that the window is still empty, not even the window frame, and the dark window looks very strange.

"What's that for? Why are there no windows?"

One of the soldiers asked curiously.

"That's our future workshop dormitory in Jiuling City."

Hasler replied with a smile.

He was originally a student in the carpentry class, but he didn't have much talent for carpentry, and his temperament of laughing and talking was in line with his mother, Aunt Mei.

Now that Aunt Mei is working as a shopkeeper in Ding'an City, his son was also discovered by Ning Zaozi's intelligent eyes and became a staff member of Mozongwu Castle's external liaison.

I have to say, this job is really suitable for Hassler!

He is a talkative person by nature, and he knows everyone by himself. If he really works hard, he will never stand in the cold, and he will soon become acquainted with Juntun.

"dormitory?"

Juntun scratched his head suspiciously.

They lived in Wupu for a month, and they are also used to some of Mo Zong's "special names", knowing that "dormitory" means a house for people to live in.

"Then why don't you worry about the windows? Isn't it cold in winter?"

Hearing his question, Hassler smiled mysteriously.

"Of course we need to install windows, but we are not in a hurry now. We will install them later."

He didn't want to say any more, and led everyone along the lake.

There are large fields beside Jiuling Lake. The corn planted before has grown green, and the black soil sets off the tender green seedlings, which makes people feel refreshed.

"This is using the fertilizer you have learned before."

Hassler introduced with a smile.

"It's just that before planting, we also put a base fertilizer on the ground. After the seedlings grow longer, we can use the seed fertilizer to help the summer harvest."

"This seedling looks raw, but it's the potatoes you mentioned?"

Old Juntun narrowed his eyes and asked.

Hassler shook his head.

"It's not potatoes. The potatoes are over there, and they will be harvested in a few days."

The direction of his finger is the tributary of Wuzhi River.

A new river channel has been excavated there, and a small dam has been built on the upper slope of the river channel, which complements the dam leading to Jiuling Lake and divides the tributary of Wuzhi River into two directions.

The potato field is on the south side of the old river, and now it is lush and green, but the eyes of all the troops are attracted by the construction site by the new river.On the bank of the new river, there are disciples of Mozong who are tying long iron rods in full swing. These iron rods are densely packed and crisscross, like a huge net, firmly embedded in the soil.

"What the hell is that? Why did they stick dirt sticks into the ground?"

A military station asked curiously.

"Oh, that's building a weaving workshop."

"There are steel bones in the cement, which is more durable than mud alone."

Hasler replied with a smile, and pointed to another building not far away.

"That's the iron workshop that was built not long ago, and further ahead are hydraulic hammers and hydraulic mills, which are used to crush ore materials."

"What?"

The old Juntun who had been silent all this time widened his eyes.

"Stone mills and hammers can also be pushed by water?!"

He thought the water dragon was magical enough, but it was made of wood after all, and it wasn't too difficult to push it with water.

But hammer and stone mill...

"Shall I... see the stone mill pushed by the water?"

Old Juntun asked cautiously.

He also knew that his request was a little too much.Mo Zong taught them all the secret recipes of farming without reservation, and now he still wants to see other people's water mills and water hammers.

Unexpectedly, Hassler agreed very happily and nodded immediately.

"No problem, it just so happens that the water mill is in trial operation for the past two days, there should be someone in the workshop."

So, with great curiosity, a group of soldiers followed Hasler towards the water mill.

The water mill is a semi-open space. In the center of the site is a huge machine made of steel. The structure is so complex and the design is so compact that it dazzles the eyes of all the soldiers.

In the huge space, the constantly rotating gears cooperate with the telescopic springs to keep running in a unique rhythm. The huge steel sheet raises a torrent, hitting the linkage rod one by one, pushing the stone mill to rotate continuously.

This is the impact force caused by the high water level difference, which pushes the simple turbine of the water oblique impact structure.The slanted turbine is suitable for small units, because it is not possible to generate electricity for the time being, so Ning Fei applied the principle to the design of the hydraulic mill.

In the whole process, there is no need for manual work, and the machine seems to have life.

All the troops were terrified.

"My God! This...what is this!? This...is this really pushed by the Wuzhi River?"

The middle-aged Juntun cried out.

Wuzhi River!He saw the big river ditch since he was a child!Although it can be regarded as a big river, but the river's level is gentle, so it can push this giant steel? !

"It's a tributary of the Wuzhi River."

Hasler said it calmly, but in fact he was screaming with joy in his heart.

Now he can be regarded as understanding why old man Liu has been walking with wind these few days, and he is full of energy.This feeling of showing off to others is really good, it's simply superior, I can't extricate myself!

When he saw the water mill for the first time, his eyes widened in disbelief, and he looked like a "bumpkin" who had never seen the world, so now he can understand the mood of these soldiers.

A millstone that turns automatically!How much power does it take to grind ore and rock? !

Such a miraculous mechanism was built by Jizi with their carpentry team!The drawings are drawn by everyone one by one, and handed over to the blacksmith for casting and polishing.Although he failed to join the research and development team because of his poor craftsmanship, he also worked hard to help everyone make paper, and then moved the parts to the iron workshop with his companions, and watched everyone install them bit by bit. baby!

He also worked hard and sweated!

Thinking of this, the pride in Hasler's heart burst instantly.

"Have you seen the dam in the Wuzhi River? When the water is stored, there will be a drop, which can make the upstream smooth and the downstream turbulent. When the water gathers together, it will have the impact force."

Speaking of this, he suddenly remembered what Juzi said on the day when the water hammer was completed, and couldn't help learning and selling, and chanted it out loud at this moment.

"Sea tides rise and fall, rivers run, this is the power of nature. Regulate it to where we need it, and promote the movement of steel, earth and rock, and we will be able to live endlessly and have no disadvantages!"

"This is the way to control nature!"
