"Helium balloon?"

Xiao Ming, who was planning the construction of agriculture and animal husbandry, almost squirted out the tea in his mouth.

Seeing this, Aster pursed her lips and laughed. She said, "His Royal Highness, what is this hydrogen balloon? It makes you so excited."

"Hey, this hydrogen balloon is a good thing, much more practical than a hot air balloon." Xiao Ming said.

Thinking about rushing to Chang'an soon, Xiao Ming was worried about the hot air balloon.

The hot air balloon of the war was so glamorous that Luo Quan was also greedy. Before returning to Chang'an, Luo Quan asked him to give one away, but he did not agree.

However, he understood that he couldn't keep hiding it all the time. To go to Chang'an this time, he must bring a hot air balloon and a musket.

This musket Xiao Ming naturally would not send the flintlock. Strictly controlling the generation of weapons and selling arms is his current basic principle.

Therefore, he was going to take the matchlock with him. With Xiao Wenxuan's character, he now had a firearm camp, and he said that he could not build another firearm camp to deter Xiao Xiao.

But the problem is that it is okay to fool the gun with the matchlock gun, but the hot air balloon has become the object of his worries, but he did not expect Lin Wentao to get the hydrogen balloon out at this critical moment.

Compared to hot air balloons, this hydrogen balloon flies higher, which is naturally a generational difference than hot air balloons.

Once the hydrogen balloon appears, the hot air balloon will be eliminated. In that case, it is better to give it to Xiao Wenxuan to sell it to increase his position in Xiao Wenxuan's heart.

After all, Xiao Wenxuan would definitely ask for these things from himself when the time comes, so it is better to take the initiative to ask him instead.

Anyway, these backward things are of little use in his hands, so why not sell them to the Imperial Army for money.

Moreover, the more arms he sold to the Forbidden Army, the tighter the curse he set on Xiao Wenxuan. Once the courtiers attacked him, Xiao Wenxuan would have to weigh the Forbidden Army's arms issue before he could deal with it.

Because without his cooperation, the artillery and muskets of the Forbidden Army would become a pile of scrap copper and iron without ammunition supplies.

Therefore, as long as he doesn't rebel, he can walk sideways in Chang'an. Because of this, he can't conceal muskets and hot air balloons. Using this as an excuse, it is estimated that many wicked people will make a fuss about this.

Now I took the initiative to send it, enough to block Yoyo's mouth.

No longer thinking about these messy things, after learning that Lin Wentao had created a hot air balloon, Xiao Ming suddenly became energetic, and he asked Zi Yu Bei Ma to come to Bowen Academy.

Bowen Academy played a very important role in the battle to expel the barbarians. One was a hot air balloon and the other was a 6-pass lime bomb.

Niu Ben praised the lime bomb when he was in Shanhaiguan. Once the bomb exploded, it could instantly make a large number of enemies lose their combat effectiveness. This was far more powerful than a simple powder can.

After this war, it has been proved that technology is the magic weapon for winning the war.

When he arrived at Bowen Academy, Xiao Ming saw a brand new hot air balloon parked on the small square in front of the College. Lin Wentao and others were discussing something in the square.

Liang Yubin and He Cheng have returned to the college, and now they are with Lin Wentao.

Seeing Xiao Ming coming, a group of students gathered around, Lin Wentao said: "Your Highness, this is the hydrogen balloon."

Xiao Ming raised his head, and a balloon the size of a hot air balloon hovered in the air, with four ropes tied in four directions of the balloon.

"How do you make hydrogen?" Xiao Ming valued this question most.

In fact, the difference between a hot air balloon and a hydrogen balloon is whether the gas in the balloon is ordinary air or hydrogen.

If it is a hydrogen balloon, even if the balloon is not heated, it has a certain lift, and this is destined to be more efficient and safer than a hot balloon.

Lin Wentao immediately became excited when he mentioned this, he said to Xiao Ming: "This is to thank the students of the School of Chemistry, they have made hydrogen, otherwise the hydrogen balloon will not really appear."

Then Lin Wenyao pointed to the gourd-like clay pot behind him and said, "His Royal Highness, hydrogen comes out of here to fill the airbag."

Xiao Ming had already noticed this thing.

He only looked at the materials around this thing and knew how the hydrogen was produced.

"Prodigal son, how much sulphuric acid and scrap iron are needed." Xiao Ming shook his head helplessly, but since letting him do it for them, he couldn't criticize too much, so he only complained and asked about who was standing on the side. Trainees.

This student is from the School of Chemistry. As he guessed, they really used the hydrogen obtained by the reaction of sulfuric acid and scrap iron, and then let the hydrogen gas into the airbag through this instrument.

Looking at the excited faces of the students, Xiao Ming didn't want to be disappointed. Although the method was a little primitive, the production of hydrogen was achieved step by step in this way.

He said to Lin Wentao: "Yes, the hot air balloon played a miraculous effect in this war. In order to commend your king, he has prepared a knighthood award for you, but this will have to wait for the Qingzhou army generals to come back and award the award together."

"His Royal Highness!"

Lin Wentao and a group of students beamed with joy, and they were rewarded with such desperately pulling the hot air balloon.

With a smile on Xiao Ming's face, it was time to award some titles to stimulate the students of Bowen Academy.

The level of science and technology in Qingzhou is not even worse than that in Europe. This requires the Bowen Institute to catch up until it becomes more comprehensive.

After understanding the birth process of the first hydrogen balloon in Qingzhou, Xiao Ming asked Liang Yubin and He Cheng to manipulate the hydrogen balloon into the air. He wanted to see the difference in height between the hot air balloon and the hydrogen balloon.

Liang Yubin and He Cheng also looked excited. Now the two of them are a little obsessed with the driving of the heater, and now this hydrogen balloon makes them even more admired~lightnovelpub.net~ The two board the hydrogen balloon, and the people below also put the rope Released, the hydrogen balloon suddenly lost its restraint and flew higher and higher.

"His Royal Highness, we are gone." Liang Yubin and He Cheng looked excited, and the two figures became more and more blurred in everyone's vision, until they turned into a small black spot.

"This is too high." Lin Wentao himself didn't believe that the hydrogen balloon could fly to such a high place.

Xiao Ming nodded in satisfaction, "Hot air balloons are only a few hundred meters high, but hydrogen balloons can fly thousands of meters high."

However, the two, Xiao Ming, who looked further and further away, became a little worried.

The current hydrogen balloon technology is not complete. He didn't want to have an accident with the two of them, but his worries were superfluous. It didn't take long for the two to lower the height and soon returned to the Bowen Academy.

Seeing this, Xiao Ming breathed a sigh of relief. Now he can take the hot air balloon to Chang'an with peace of mind. I hope he can sell it for a good price.
