"Mr. Qin, Mr. Qin. Old decay is coming. A voice in the distance reached Shang Wen's ears.

Shang Wen took a look.

"Hi Lao. How do you get here. So far away," Shang Wen said, holding Xi Lao. "Hey, no, no." Xi Lao smiled and waved his hand. "This is the order of the King of Qin to send a part of the skilled craftsmen to the north. I don't have anything to do in Xianyang. I'm here. Here, I'll see if I can help you. Xi Lao said happily. Why do you bother that? Shang Wen hurriedly helped Xi Lao. Old though old. But the heart is not old. Xi Lao said with emotion. Yes, yes, the heart is not old. Shang Wen helped Xi Lao to go to rest quickly.

The next morning, Shang Wen had just fallen asleep when he saw Ying'er standing at the door of the tent. Both eyes are red. "Sir." "How..." said both at the same time. "Let's talk about it first." Shang Wenqian arrived. "Sir, we've already finished making that thing you asked me to make. Go over and have a look. If it's not good, we'll change it. Ying'er whispered.

"Look at your eyes, you haven't slept all night. Okay, I'll take a look. Shang Wen said.

The two came to Ying'er's residence. I saw that the designed airbag had been placed on the ground. The overall effect is almost the same as that of my own design. Shang Wen walked in quickly. Picked it up and looked at it.

The pins are not ordinarily dense. on every road. There are five ways. Such a large amount of work. It's all thanks to these weak women. I really don't believe it. Shang Wen couldn't help but shake his head.

"Why, sir, isn't it appropriate. The slave and maid will change it. Ying'er saw Shang Wen shaking her head and said.

"No, it's not. I just didn't think of it. You weak women. It was made overnight. It's unimaginable. It's a miracle. What a miracle. Shang Wen sighed.

"Sir. This is what slaves and maidservants should be. Ying'er said with a smile.

"Alright. You've stayed up all night, too. Hurry up and get to rest. Eat something. I'm going to experiment with it. With that, Shang Wen began to call people outside.

"Whoa." Ying'er said with the weak women.

"No need to be polite. Hurry up and eat and rest. Shang Wen said again.

In an open meadow. Several people gathered around the airbags. "Add a fire." Shang Wen said anxiously.

A soldier quickly refueled. The fire was much more intense at once. The airbag is just a little up at the entrance. The rest of the place. There was no movement.

"Add a little more". Shang Wen said.

"Can't add more. Plus. The hoops were all burned red. The soldier said.

"Oh well. So be it. Shang Wen said with some frustration.

How could this be. Could it be that something is wrong with that piece? The airbag cannot be inflated. Is it that the firepower is too small. Shang Wen crossed his arms. One hand held his chin and pondered.

"Shangwen, I don't know, what you did. But I think. That's not right. Xi Lao said on the side.

"Oh. Hi Lao, what do you think. Shang Wen stopped thinking and asked.

"I think. It should be made a shelf. Lined inside. It's much better that way. Xi Lao pointed to the airbag and said.

"Yes, yes. But the weight. Shang Wen looked at the airbag and said.

"That's fine. I make it with bamboo. It's very thin. Very light. That's it. Xi Lao said.

"Well, I'll give it a try. Then I'm going to be in trouble with you. Shang Wen was a little hesitant, but considering the benefits of the shelf, he agreed.

"Xi Lao, you go to make a shelf, and I'll improve the Spitfire equipment." Shang Wen said.

"Okay, okay." Xi Lao said happily.

To increase the fire-breathing equipment, it is necessary to provide a certain amount of oxygen supply. You can't just refuel.

And to provide it in a short period of time. What to do. Shang Wen thought as he walked.

Yes, using the same principle as a pump. Mix oil and gas. A piece is compressed into the spout. In this way, a large flame and high temperature can be generated in a short time. Persistence. Gears can be employed. This will be gradually improved later.

Thinking of this, Shang Wen immediately found Xi Lao. Told myself a preliminary idea.

After listening to this whimsy. Xi Lao did what Shangwen meant. I pondered for a day. I finally saw the real thing.

A long, large bamboo tube. There is a lever attached to one end. When the lever drives this air lock downward. A certain amount of oil is mixed with air into the bamboo tube. Then start compressing upwards. This time. The fire broke out all at once. It caught fire with a "boom".

Look at the fire that burst into the sky. Shang Wen smiled happily. Xi Lao was taken aback.

Since all this was done, it was already the middle of the night. Shang Wen was still thinking about experiments. But it seems that it is no longer possible. I had to go to bed and rest.

The next day, before dawn, Shang Wen got up. Yesterday Shang Wen didn't fall asleep all night. Excited.

The soldiers fought Hache. Reluctantly moved. Shang Wen can not care.

Several soldiers carried a behemoth to the experimental site. The weight is not very heavy. Four people do it easily. Taking into account the characteristics of bamboo. Shang Wen still asked more than a hundred soldiers to carry it. But the size of the airbag is too large. It's as tall as a three-story building. The length is about seven zhang. That's what they said, and Shang Wen didn't know how long it was.

Placed on a makeshift wooden platform. Erect the air intakes. Shang Wen personally added gas.

Shang Wen shook the lever on the hot grass. The fire, "whirring" is rising upwards.

Many people saw such a fire and thought it was on fire and rushed to put out the fire. But he was stopped by someone who knew the inside story.

The fire began to grow. The airbags are slowly rising. The large basket in which Shang Wen sits. Began to slowly lift.

The onlookers were a little surprised, but more delighted. Ying'er also saw so many people walking out. I also went out with the sisters to see.

I saw that the thing called the airbag that I had sewn was flying. And Mr. Qin is trying to shake the handle or something.

Ying'er exclaimed, "It's flying." "The hot air balloon is already twenty paces away from the ground. And it's rising.

With Ying'er's exclamation. All of them recovered from the shock.

"Oh." A bang. Everyone started pointing to the flying hot air balloon.

"Flying." "Flying." All of a sudden, everyone started yelling.

"Flying. Really fly. "Fly into the sky. Fly into the sky. The crowd began to cheer.

Meng Tian heard everyone's movement and hurried over. Before I got off the horse, I saw a hot air balloon flying up. I was stunned all at once. Almost drew his saber. "This guy is too godly, isn't it? Even the sky can go up. It's just a god."
