In a blink of an eye, more than twenty days have passed, and the end of the year has finally arrived.

Eating and having fun along the way. Although it was a disaster year, the big cities were not affected too much because of their effective protection. So Wuyou gained at least five kilograms. The originally thin melon-shaped face was already obvious that the baby belonging to the girl was fat. Song Beiyun even considered whether she could raise this junior sister to 180 kilograms. Then she could shake up a big sword of 180 kilograms. If she danced, wouldn't she have to go to heaven?

On the way back, Song Beiyun happened to pass by a farm. He had passed by the same farm as the big and small farms on the road, but Song Beiyun always felt something was wrong. He had already walked several miles, so he insisted that the driver drive the car back.

When he parked around the farm and got off the car and checked it, he found that this place was really different from other places, because there were still wintering food in the fields, mainly wheat and some cold-resistant vegetables.

This is unreasonable, because although the drought has been alleviated, judging from the growth of these crops, it was obviously sown a few months ago.

When I walked into the village house, I even found that many people around me had a lot of grain piled up in the yards of many families. Although the things were very mixed, they were real grain.

"My husband, what's wrong?"

Qiaoyun chased after him and asked, "What did you see?"

"This is not right." Song Beiyun's face was full of curiosity: "Are we all the way we have been particularly desolate? How can we grow food in this place after a whole year of drought?"

Qiaoyun then discovered the problem, but after all, she was not a technician, and all she could do was follow Song Beiyun to investigate. Wuyou said carelessly: "I'm afraid there are no monsters."

"Monster." Song Beiyun chuckled: "All monsters, evil spirits, monsters, snakes and gods are fake, and there must be problems with abnormalities here."

So he found some farmers on the roadside and asked, but what made him feel strange was that no matter how he asked, the farmers here kept silent and even looked at Song Beiyun with careful eyes, as if he was afraid that he would know something.

But the more this happens, the less his curiosity is satisfied. When the desire for knowledge is caused, Song Beiyun simply stopped leaving and just squatted on the side of the road.

This squatting made it difficult for the people in the village to destroy the people. They tried to come and be fierce, but when they saw the big sword like a door panel beside Wuyou, no one dared to go forward and persuade him with kind words, but who knew that Song Beiyun would not enter and not find out the truth, he would not leave.

"Scholar, what are you waiting for? Go up and catch someone and ask, and then beat him if he doesn't answer."

Wuyou was not patient. She was fierce and said fiercely: "This group of people is so hateful!"

"You know how to fight and kill at such a young age." Song Beiyun waved his hand: "You wait for me here, and I'll go in and take a look."

Wuyou wanted to follow in. After all, she had to fulfill her duties as a bodyguard these days, but Qiaoyun grabbed her arm after she had just walked a few steps. Qiaoyun said with a smile: "Let him deal with it by himself. There is nothing in the world that can make things difficult for him."

"I don't believe that if he was so godly, he would have been the prime minister long ago."

Qiaoyun smiled without saying a word...

Song Beiyun bought a piece of oil cake in a small shop on the side of the road. After taking a bite, he smiled and said to the boss: "Boss, this oil cake is fresh flour, which is amazing. You can eat fresh flour in this disaster year and sell it."

The boss saw him look and waved his hand impatiently, "Don't delay my business if you don't buy it."

Although Song Beiyun was driven away, he already understood something in his heart. The people in this place were indeed able to grow food themselves. They planted food themselves and also ate relief issued by the court, as well as various tax exemption policies. This disaster year is naturally more nourishing than in previous years.

Now Song Beiyun wants to know what exactly allowed them to grow things under such drought.

After walking around the village, I found that the place was not big, with only a hundred people, about the same size as Xiaolian Village. It was a remote place where the county was not very willing to take care of.

It is still surrounded by mountains and water, but the water in the river is not turbulent, but it looks like a stream. This is still the state after the drought is relieved. It is estimated that at the worst time, the river will probably have cut off its current flow.

Walking further forward, he was not allowed to pass. A few young men were guarding outside a low wall, staring at the surroundings with fierce eyes. When they saw Song Beiyun approaching from afar, they asked him to leave.

"Huh?" Song Beiyun didn't walk far away. After walking around here for a few times, he found that this place was strange.

There are no houses in this yard, but there are a few big flagpole-like things inside, and there are bamboo-like things piled up on the surrounding walls, which makes people feel overwhelmed.

Just as Song Beiyun was studying these things, an inconspicuous little thing suddenly caught his attention. It was a piece of copper wire, which should be a discarded part of the copper wire.

He bent down and picked up the copper wire, and found that the copper wire had actually mixed with some kind of glue on the outside to make an insulating layer.

"No."

He looked at the tall poles standing in the yard, then at the small piece of enameled wire in his hand, and suddenly a thought came out of his mind, this place would not be generated by wind power, right? This little place? This place where birds don’t shit?

Song Beiyun didn't say anything, but just turned around and found a blind spot to observe. Then he was too lazy to worry about his image, and sneaked over the low wall and entered the yard.

After entering the yard, he first saw about four or five holes the size of a bowl on the ground, which were bottomless.

He leaned over and knocked, and found that water vapor could be vaguely rushing inside. He picked up the scattered stones next to him and threw them down. He began to recite silently in his heart. He only heard a gurgling sound of falling into the water after about five seconds.

He immediately understood that these holes were wells! The water veins hidden underground were opened here!

Based on rough calculations of gravity acceleration, the depth of this well actually reached more than 120 meters.

This is almost impossible to accomplish in this era! Because there is not that long drilling tool.

Song Beiyun was confused at that time. Wind power generation and deep drilling technology were actually used first in this place. Although salt well technology was available for a long time, it belonged to large shallow wells and drilling technology, which was completely different from drilling technology, so there must be something strange here.

This guess is much more exciting than punishing a poor little prince. Two possibilities immediately appeared in Song Beiyun's mind. One was that time travelers appeared, but this was quickly denied because even time travelers could find it difficult to complete such hard-core engineering design without relying on productivity.

Another thing is that there is a genius among the people. After this genius got some inspiration, he drilled the place in a very special way.

But if drilling technology is easy to explain, how can wind power be explained? Indeed, Song Beiyun has divided electric power into one category, and proposed electromagnetic conversion and other contents, and compiled the electromagnetic induction enlightenment and coil technology compiled by Miaoyan, but he does not expect anyone to understand this thing now!

So Song Beiyun didn't care about anything now. He climbed over the wall and directly found the owner of the village household, who was a village chief, and revealed his identity.

Although the owner of the manor was also an honest country man, he was shocked when he saw Song Beiyun reveal his identity as a person in the court. Later, under Song Beiyun's impolite questioning, he patted his chest on the spot and said that everything was done by him and had nothing to do with others.

That's what Song Beiyun can say... He is considered a ghost if he can believe that he is just a person who doesn't even understand what a coil is. If he wants to make this thing, it will be more difficult than climbing to the sky.

So Song Beiyun threatened directly: "You said it's okay now. If you don't say it, I will say that you use magic to get water and harm the surrounding neighbors."

"Sir... it's really me, sir..."

The owner of the manor was about to kneel down for Song Beiyun, but he suddenly heard a "Stop it" from outside.

Song Beiyun looked in the voice and saw a young man in his twenties standing at the door. His dress was not like a scholar, and he was holding a blacksmith's hammer in his hand. His eyes were firm when he stood there.

"I did it. I'll kill you and scramble to me, regardless of the owner's affairs!"

Song Beiyun tilted his head and looked at the man: "So you did the excavation drilling and wind power?"

When the young man heard these two nouns, his expression changed: "Are you from the Academy of Sciences?"

Song Beiyun laughed and immediately confirmed that what the boy in front of him did. It was the Academy of Sciences that could immediately reflect that it was the Academy of Sciences, which means that he knew in his heart how this thing came about.

"Yes, right?" Song Beiyun put his hands behind his back: "Follow me."

The two of them came to the wells, and Song Beiyun pointed to the wellhead on the ground: "I have two questions now, one is how you drilled so deep. The second is how you pumped the water up."

The young man looked at Song Beiyun carefully, then fell silent: "You don't understand."

"Stop talking nonsense to me, just say it if you want me to say it!"

"It was learned secretly..." The young man's tone gradually weakened: "I..."

"Study secretly? Where?"

The young man never mentioned it, but Song Beiyun believed that someone should have brought the enlightenment of these technologies out of the big library and gave it to him, and he refused to betray the person who taught him.

But this is not the point. Knowledge is meant to be spread. Such a genius is simply a treasure of engineering. The engineering academy under construction now lacks such genius who can integrate them.

"I can probably think of what kind of drilling method you do, but I still want to hear you talk about it myself." Song Beiyun made a drilling gesture: "And I also know that your unique skill is to carve the inner rifle, and then lure the mud into the hollow drill bit, and then dig it slowly, right? So you should have come back from Tongling Arsenal."

The young man looked at Song Beiyun in disbelief: "How...how did you know?"
