The weapon tycoon who traveled to Daqin

"We're in an ambush, hurry up, retreat quickly." The Hu people who realized that something was wrong began to exclaim. However, it was already too late. Rockets with smoke began to appear on the south and north slopes. Although they were small, they were lethal.

The force is not weak at all.

The whistling rockets fell densely. The dense formation became a good target. A small area was hit repeatedly by rockets.

Before "Bao" had finished speaking, Natulu was directly focused by the flying rockets. His whole body was shattered by the blow. Only two legs were still hanging on them. The entire upper body was gone. The rockets that fell later were completely destroyed.

The remaining rotten meat is crushed into meat sauce.

"Boom, boom, boom" round after round of rocket bombings knocked all the Hu people's few troops to the ground. After a thick smoke, only the horses were left grazing alone on the battlefield.

"I thought I could kill a few people when I went down, but I didn't expect them all to be killed. This saves my worries," a corps leader said.

"Commander, a group of enemies has escaped. Should we pursue them?" a centurion asked the bearded man.

"No need. Clean the battlefield. Send out scouts and monitor closely." The captain waved his hand and said.

"Here." The centurion began to arrange his men. The rest of the men went down to cut off their heads.

Naofumi beat this beat on his legs, thinking about how to solve this difficult problem. Obviously, this problem is difficult to solve.

First of all, the Qin army expanded very quickly. The problem of the Huns in the north was completely solved in one battle. In the future, there will be no need to build the Great Wall. Moreover, they can get a large piece of pasture for no reason. The soldiers of the Qin army will be able to

Now I can eat beef. Maybe I can even eat canned beef in the future.

Secondly, almost all the Huns were captured as slaves, but leaving such a big vacuum is difficult to fill in a short time. This is also a problem. Mainly people. Our Guyang Iron Works has just been established. It requires a large number of people.

People. And with the demand, especially for trains, an astonishing amount of iron is needed. It is another problem.

Finally, as the market becomes larger and the population decreases, a fast communication system is needed. The communication system based on the current post station can no longer meet the requirements. The territory is too big. This battle has expanded at least one

A territory of more than a thousand miles. And this number is still growing rapidly and exponentially. What a difficult problem.

Naofumi thought about these things and had a headache. He thought that when the cannon went off, there would be ten thousand taels of gold. But now he didn't see a penny. He only saw infinite land and a lot of bad things. Expanding too fast was also a problem.

Forget it, leave it to the politicians.

"It seems that we have no choice but to send another group of scouts." After saying that, Wang Jian stood up and went outside to give his orders.

Meng Tian was also gloomy and gloomy. It seemed that he didn't know the situation ahead at all. If you don't know, you can't send troops hastily.

"It would be great if I could fly like an eagle in the sky. This way I can quickly deliver information." Meng Tian said to himself.

Fly, sky, sky. When Shangwen heard Meng Tian say such words, he suddenly felt inspired.

"I thought of it. I thought of it." Naofumi shouted, clapping his hands.

"What?" Meng Tian stood up immediately and said.

"I think you can order people to catch some hawks and train them. Those hawks can help you deliver messages. Besides hawks, are there also flying pigeons?" Naofumi said.

"Fei Ge. It's been done before. But it's not safe and I haven't tried it yet." Meng Tian said.

"That's no problem. Flying pigeons can fly very well. It's not safe. You can set up a password. For example, you can write the same sentence separately or wrongly. Or you can add a word to make it mean that word.

." After saying this, Naofumi realized that at this time, it was not because of the letters, but it was Morale code.

"This is fine. I'll give it a try." After saying that, Meng Tian turned and left.

"Heaven. Heaven. Originally, I planned to build an internal combustion engine and then gradually build an airplane. Now it seems that I don't need to build an airplane anymore. I have to build a hot air balloon." Naofumi said to himself.

"What hot air balloon?" Wang Jian suddenly came in from outside.

"Ouch." Naofumi was startled.

"It almost scared me to death." Naofumi said, patting his chest.

"Mr. Qin, what is that hot air balloon you are talking about?" Wang Jian asked.

"This, this is something that can fly into the sky. With this, we can see the situation in the distance. As long as we build more, it will become an active beacon. With clairvoyance, we can see more things.

." Naofumi explained.

"Go to the sky. This thing can go to the sky! It can fly like a bird." Wang Jian exclaimed, holding Shang Wen's hand tightly with his thick hands.

Shangwen tried hard to break free from Wang Jian's hand. Realizing that it hurt Shangwen, Wang Jian hurriedly let go. "I'm sorry, I'm sorry, Mr. Qin, I forgot about it as soon as I heard it." Wang Jian apologized quickly.

"Nothing, nothing. This hot air balloon uses the expansion of hot air to create buoyancy. It just needs to heat the air with fire." Naofumi explained clearly.

"What, buoyancy? Buoyancy does not exist only in water. How did it get to the sky?" Wang Jian continued to ask.

Naofumi was a little broken. Do he still have the knowledge of popular science?

"Well, I'll make one over there. When it's done, can you go and have a look?" Naofumi said.

"Okay, hurry up. The military situation is urgent." Wang Jian said.

"I'll go right away. I'll go right away." He said and ran away like flying.

Wang Jian's hand was so strong. My hand was almost broken. Shangwen relaxed his red hand.

Air Force. I actually want to build an air force. Or a hot air balloon. At this time, it seems that there is no cotton silk. Also, paper is not that thin. Well, to solve this problem, I have to make one more trip.

Fuel. This is easy to say. We want to build roads and have begun to mine and process oil on a large scale there. We have produced a large amount of diesel, gasoline, kerosene, aviation kerosene, and asphalt. The most important thing is oil. But now we are putting the cart before the horse.

For highways, I don’t know what the proposed oil can be used for. Now it’s ready. It’s just right. It can be used in hot air balloons. I’m afraid it won’t be fully burned.

Ignition device. This seems to have to be made of iron. At least it has to be made into a gadget like a kerosene lamp.

Okay, that's it. Naofumi thought about the composition of the hot air balloon and any materials he could find. He gradually formed a rough composition in his mind.

After thinking about all this, Shangwen quickly got in the car and ran to Guyang Iron Factory to make hot air balloons. As for the iron factory, he didn't care about it for now.
