The families of the original Jin Yuan soldiers moved to the four cities of Hexi one after another, and the families of the Haotian soldiers also came to the door, and the population of the four cities of Hexi suddenly increased by one-third, and the excitement of the city was unprecedented, because there was no threat of war, some people also put aside the comfortable environment in the city and moved back to the original village.

Many people also moved to the other side of the river in Hexi City, and as the first batch of people to open up the wasteland, they received strong support from the Leiming officials, who repaired roads for them and helped them build houses......

Early in the morning, the sun is shining, and the wind is blowing, and there is an endless stream of cultivators along the Hexi Bridge, or carrying burdens, or pushing carts, or holding cattle...... In short, it was very lively.

Lei Ming, Huang Chu, Luo Yangtian, and Yang Tian walked on the Hexi Bridge, and people greeted them and made way for them all the way. Lei Ming was very satisfied and contented in his heart.

Huang Chu smiled and said: "General Lei, General Yang, one of you is in charge of political affairs, and the other is in charge of war, and now the four cities of Hexi are really singing and dancing." Soon the people will be afraid that they will offer you two up and worship you as gods. ”

"I'm afraid it's not your share, Mr. Huang!" Luo Yangtian said with a smile on the side.

Yang Tian glanced at Luo Luotian and Huang Chu, and said with a grin: "All have a share, all have a share, and those who see it have a share." ”

"It's all nonsense!" Lei Ming looked at the crops in the distance as he walked with his hands behind his back, "By the way, where has Meng Fan gone?" he looked back at Yang Tian.

Yang Tian smiled and said, "He went to Haoyue to open a martial arts hall, and he said that he wanted to promote the belief and martial arts of Tianwumen. "The appearance of Luo Ming in Haoyue City has left a great shadow on Yang Tian. I didn't expect Meng Fan to preach Tianweimen there, and only teach Tianweimen martial arts, not him and Lei Ming's martial arts, and not teach the martial arts of going into battle to kill the enemy. This is to establish a sect in Haoyue Tianmen.

"His Tianwei Sect is going to be openly established?" Lei Ming was also surprised, why did Tianwei Sect change its normality?

"Maybe they think Haoyue City has enough force to protect them. The corners of Yang Tian's mouth twitched. In the past two years, they have produced more than 2,000 sniper rifles and steel cannons, and there are also more than 200 submachine guns, of which nearly half are used in Haoyue, and the rest are in Baishan.

"Well, that's a good thing, too. It means that they depend on us. Luo Yangtian nodded.

"What about Qin Hao and Yang Erwu?" Lei Ming has been busy with production recently. Ignore their situation.

"They're either mixed in the special combat team or in the elite battalion, don't worry, no one can bully them. Yang Tian snorted, in peacetime. He didn't have anything to do. It's all tossed by them. Old man Yang Fu was immersed in the machine of the white mountain. Indulge in a variety of ingenious design ideas and crafts.

"It seems that there is nothing to keep us busy now, everything is on track, just waiting for time to settle. Huang Chu stroked his beard and smiled comfortingly. The prosperity of the four cities in Hexi. Indeed, he has a great merit.

Hearing this, Lei Ming couldn't help but stop, looked back at Yang Tian, who was also stunned, and frowned: "No, there are still many things to do." For the two scientists, martial arts is not their specialty, but R&D and preparation are their forte.

After being silent for a while, Lei Ming looked at the river with white waves under the bridge, and said abruptly: "If there are more copper mines, the things produced will be richer." ”

Huang Chu and Luo Yangtian didn't know why, Qi frowned and pondered, waiting for Lei Ming to give an answer. Yang Tian smiled and said, "You can send someone to find a copper mine, anyway, it's not the first time you're looking for a mine." ”

Lei Ming choked for a moment and said, "How can this thing be so easy to find, it's luck to encounter it, and it's fate to can't find it!"

"Hehe, I have an idea, the manpower and equipment are insufficient, that is, make more explosives and go to the mountains to blow them up! It is easy to find minerals when they are blown up!" Yang Tianyan said with a smile, he imagined that even if he could not blow up minerals, this way of burying ammunition could greatly train soldiers, and it would be of great use on the battlefield in the future.

Lei Ming rolled his eyes, sighed and said, "Alas, then it's up to you, there is no drilling equipment, it's really troublesome." But if it's on flat ground, won't you find it?"

"What you said, I can't find it!" Yang Tian shrugged, looking unconcerned.

The steam engine had already been designed and manufactured by Lei Ming, but that thing was large in size, and there was no output of electrical energy, only power transmission, which was not conducive to mass use, and only four were used for forging metal workpieces and two for weaving cloth in Baishan. He thought that he could find copper ore and make it into wires to export electrical energy and then spread it widely.

A large amount of explosives began to be manufactured by Yang Tian, and he led a special combat team to test it on the sparsely populated Haoyue Mountain, and from time to time he could hear a loud "boom" on a sunny day, and then the ground shook......

A month later, the people of Haoyue City had become accustomed to an afternoon of explosions, and after a loud bang, the explosions stopped. It turned out that after Yang Tian's many explorations, a deep blast came, which actually made them lucky to find the red copper!

I saw a special combat soldier break through the dust and fog in dust, and rushed out with a piece of red metal in his arms, shouting: "General Yang, General Yang, look at what this thing is!"

Yang Tian heard the cry of joy, and knew that he had made a discovery, so he flashed a few times, came to the running man, stopped him, looked at the thing in his arms with glowing eyes, and said, "Wu Yong, stop! Give me the thing in your hand!"

Wu Yong was startled at first, but when he saw that it was Yang Tian, he hurriedly lifted the red thing in his arms in his arms, and gasped slightly: "Here, general, see what this thing is?"

It was the size of a basketball, but it was not at all regular, it looked red, reflecting the luster of metal from time to time. Yang Tian stretched out his left hand to support it lightly, but it was cold and heavy in his hand, and he almost dropped the ore on the ground, which frightened him so much that he was busy lifting his strength before he could hold up the thing in his hand smoothly, and he did not make a fool of himself.

Yang Tian looked left and right, and couldn't see the reason, he only felt that this thing looked like red copper, but it had to be confirmed by the ingredients. He carried the ore up to a few dozen meters, found a flat stone and put it down, took out the dagger from his foot, and swiped lightly, leaving a deep scratch on the ore.

Looking at the smooth incision and crimson color, Yang Tian's smile couldn't help but quickly spread from the corners of his eyebrows to his entire face, and then he laughed wildly: "Ha Lu Ha!

Wu Yong behind him was also full of joy when he heard it, and after spending a month of non-stop blasting, he finally had a harvest after blowing up Haoyue Mountain into potholes!

The news and samples were delivered to Lei Ming of Baishan the next day, and without saying a word, he took the samples to a small laboratory and took the samples for a chemical determination.

The blue solution was prepared quickly, and it was soft and malleable, and it was so malleable that thunder was almost certain that it was red copper!

As a result, Haoyue Mountain began the mining development vigorously, the five-meter-wide road was quickly pushed out, the steel cable was also straightened as a necessary tool for transportation, and the movable pulley was used in large quantities......

And in Baishan City, Lei Ming also personally went into battle, he wanted to use the newly obtained copper wire to make a generator, the large natural magnetic ore was not found, but he prepared an artificial magnet by himself......

In a blink of an eye, another three months passed, and Lei Ming finally built the power generation unit and connected it to a newly made steam engine.

The machine started with a hum, and he didn't know the specific voltage, but the theoretical value, he estimated that there were 10,000 volts!

He didn't have any measuring tools, so he found a large basin of water, which contained two large carps of six or seven catties. Connect the two wires, as soon as the machine starts, I see two carp directly turn their stomachs, and then the water mist in the basin surges, which is too hot.

Lei Ming was full of joy everywhere, and the joy was overflowing, and he said to Yang Fu who was watching: "With this electricity, things will be much easier in the future." ”

Yang Fu didn't think so, this laborer killed two fish in a hurry, what kind of good thing is it, he thought to himself, but he still smiled on his face to accompany his grandson, he was happy, the old man was happy, just toss with him.

The days of hard work and fruitful results are both fulfilling and satisfying. No, in half a year, Yang Tian has successfully developed a variety of hand-cranked generators, there is no other use, it is a must to use electric fish, as long as the hand is shaken, the fish in the water will be large and small and tumbling, and then stop to pick up the fish......

The light bulb was also invented, but the voltage was unstable at first, and it burned out when it was lit, which made Yang Fu, Huang Chu and others excited in the light for a while, and then fell into the darkness......

After several twists and turns, Lei Ming finally adjusted the output ratio, so that the voltage fluctuated within a very small radiance, and the lights on the light were no longer so easy to burn out, and in the humming of the steam engine not far away, the city lord's mansion could finally enjoy the bright lights.

Listening to the noisy sound, Old Man Yang Fu couldn't help but ask: "Thunder, can you not let it sound over there, but you can enjoy this light?"

Lei Ming said with a bitter face: "It can be, as long as the wire is longer and the machine is moved farther away." We're not still experimenting. "In fact, Lei Ming also has a headache for that sound, but it is only in the trial stage, and it has not yet been fully rolled out, and it will be fine after the implementation of hydropower or coal power plants......

"Then you have to find a way to move it, this thing is noisy, and I can't sleep well. Yang Fu frowned and complained.

Shrugging his shoulders, Lei Ming said helplessly: "Just turn off the machine, but we have to light the lights again." (To be continued......)
