"There is an ambush in the middle, quickly, quickly retreat". Realizing that something was wrong, Hu Ren began to exclaim. However, by this time it was already too late. Smoke-strewn rockets began to appear on the hillsides to the south and north. Although it is small, it is not weak at all.

Whistling rockets rained down in a dense manner. Dense formations make good targets. A small area. Repeatedly hit by rockets.

The "newspaper" had not finished speaking, and Natulu was directly concentrated by the flying rockets. The whole body was shattered by the blow. Only the two legs are still diagonally resting on it. The entire upper body is gone. The rockets that then fell completely smashed the remaining rotten meat into meat sauce.

"Boom, boom, boom" round after round of rocket bombardment. There will be only a little team of the Hu people. All crashed to the ground. After a puff of smoke. Only the horses were left grazing on the battlefield.

"I thought I could cut a few people down there. I didn't expect them all to be blown up. It's also worry-free. A captain said.

"Commander, one of the enemies has fled. Do we chase or not? A centurion asked, bearded.

"No, I don't. Let's clean up the battlefield. Send out scouts. Closely monitored. The commander said, waving his hand.

"Whoa." The centurion began to arrange manpower. The rest of the people, go down and cut off their heads.

Shang Wen slapped the beat on his leg. Thinking about how to solve this big problem. Obviously, this problem is difficult to solve.

First of all, the Qin army expanded very rapidly. The first war completely solved the problem of the northern Xiongnu. In the future, there will be no such thing as building the Great Wall. And you can get a large area of grassland for no reason. The soldiers of the Qin army will be able to eat beef in the future. Maybe you can eat canned beef in the future.

Secondly. The Huns were almost all taken into slavery. But leaving such a large piece of vacuum. It's really hard to fill in a short period of time. This is also a difficult problem. Mostly people. Its own Guyang Iron Works has just been established. A large number of people are needed. And with the demand. In particular, the amount of iron needed for the train is staggering. Another conundrum.

At last. The market is big. The population is smaller. A fast communication system is needed. The current post station is the communication system. It is no longer possible to meet the requirements. The turf is in is too big. This battle expanded the territory by at least more than 1,000 miles. And this number is growing exponentially at a rapid rate. It's a problem.

Shang Wen thought about these things. Headache no. I thought that when the cannon went off, there would be ten thousand taels of gold. I don't see a penny now. I saw only the infinite land. There's a whole bunch of. Expanding too quickly is also a problem. Forget it, these are left to the politicians to solve.

"Looks like we're going to have to send another batch of scouts." After speaking, Wang Jian had already stood up. Go out and command.

Meng Tian is also gloomy. It seems that the situation ahead is not known at all. If you don't know, you can't rush to send troops.

"If only I could fly like an eagle in the sky. This allows for the rapid transmission of information. Meng Tian said to himself.

Fly. Heavenly. Heavenly. Shang Wen heard Meng Tian say such a sentence. Suddenly, there was a hint of inspiration. "I thought about it. I've got it. Shang Wen clapped his hands and shouted. What?" Meng Tian immediately stood up and said.

"I think you can order someone to catch some eagles and train them. Those eagles can help you get the word out. And in addition to the eagle. And flying pigeons? Shang Wen said.

"Flying pigeons. There have been before. But it's not safe, and I haven't tried it. Meng Tian said.

"That's fine. Pigeons are very capable of flying. It's not secure, you can set up a password. For example, in the same sentence, you can divide the development. Or yes. Wrong development. Or just add a word to make it the meaning of that word. After speaking, Shang Wen realized. At this time, there is not yet because of the letters. That's Moore yards.

"That's fine. I'll give it a try. After speaking, Meng Tian turned around and left.

"Heavenly. Heavenly. Originally, I also planned to build an internal combustion engine. Gradual construction of airplanes. Now it seems. No need to build airplanes. I've got to build a hot air balloon. Shang Wen said to himself. What hot air balloons? "Wang Jian suddenly came in from outside." Oops. Shang Wen was taken aback. I'm scared to death. Shang Wen patted his chest and said. 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. There you have this. You can see what's going on in the distance. Just make more. It became a beacon of activity. Plus clairvoyance. We'll be able to see more. Shang Wen explained. Heaven. This thing can go to heaven! Able to fly like a bird. Wang Qian's thick hand held Shang Wen's hand tightly and shouted.

Shang Wen struggled to break free of Wang Qian's hand. Realize that it hurts Shang Wen. Wang Jian hurriedly let go. "I'm sorry, I'm sorry, Mr. Qin, I forgot as soon as I heard it" Wang Jian hurriedly apologized.

"Nothing, nothing. This hot air balloon is made use of the expanding hot air. formed by buoyancy. Just heat the air with a fire. "Shang Wen explained.

"What, buoyancy. It's not in the water to have buoyancy. How did it get to heaven". Wang Jian continued to ask.

Shang Wen was a little devastated. Do you still have the knowledge of popular science?

"So, I'm going to make one, and when I'm done, can you go and see?" Shang Wen said.

"Okay. Be quick. The military situation is urgent. Wang Jian said.

"I'll go. Here it goes. As he spoke, he ran away.

This Wang Jian hand is too strong. My hands are almost broken. Shang Wen relaxed his red hand.

Air force. He even wants to build an air force. Or a hot air balloon. At this time, it seems that there is no cotton silk. Also, the paper is not so light and thin. Well, solve this puzzle. I have to make one more trip.

Fuel. It's good to say that he wants to build a road, and he has already started to extract oil on a large scale. And it is processed. Raised a large amount of diesel, gasoline, kerosene. Aviation kerosene. And asphalt. The main thing is oil. Now it's putting the cart before the horse. For the highway. Those who put up the oil don't know what to do. It's good now. Just right. Can be used on hot air balloons. I'm afraid I won't be able to finish the burn.

Ignition device. It seems that iron is also necessary for this. At the very least, it has to be made into a knack like a kerosene lamp.

Yes. That's it. Shang Wen pondered the composition of the hot air balloon. and any material that can be found. A rough composition is gradually formed in the mind.

Think about it all. Shang Wen quickly got into the car. I went to the Guyang Iron Works to make hot air balloons. As for the ironworks. Don't worry about it for now.
