"Hydrogen balloons?"

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

Seeing this, Aster pursed her lips and laughed, and she said, "Your Highness, what is this hydrogen balloon?" Makes you so excited. ”

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

Thinking that he was about to rush to Chang'an, Xiao Ming was worried about the hot air balloon.

The hot air balloon of this war can be said to be a great shine, which made Luo Quan also greedy, and before returning to Chang'an, Luo Quan asked him to send one with a dead face, and he did not agree at that time.

However, he understood that he couldn't hide it all the time, and this time he went to Chang'an, he must bring hot air balloons and muskets.

This musket Xiao Ming naturally will not send the flintlock pistol, and strictly controlling the difference in the generation of weapons and selling arms is his basic principle now.

Therefore, he is ready to bring the arquebus, with Xiao Wenxuan's character, now that he has a firearms battalion, he can't say that he will build another musket battalion to deter Xiaoxiao.

But the problem is that it's no problem for the musket to fool around with the arquebus, but this hot air balloon has become the object of his worries, but he didn't expect Lin Wentao to get the hydrogen balloon out at such a critical moment.

Compared with the hot air balloon, this hydrogen balloon flies higher, which is naturally more than a generation difference than the hot air balloon.

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

After all, Xiao Wenxuan will definitely ask him for these things at that time, and it is better to take the initiative to give them to him than to ask him for them.

Anyway, these backward things are not of much use in his hands, so why not sell them to the forbidden army for money.

Moreover, the more arms he sells to the forbidden army, the tighter the spell he puts on Xiao Wenxuan, once the courtiers attack him, Xiao Wenxuan has to weigh the arms problem of the forbidden army before he can deal with it as appropriate.

Because without his cooperation, the artillery and muskets of the Forbidden Army would have been left without ammunition and would have turned into a pile of scrap metal.

Therefore, as long as he does not rebel, he can walk sideways in Chang'an, and because of this, he can't hide the matter of muskets and hot air balloons, and use this as an excuse to estimate that many people with bad intentions will make a fuss about this.

Now that I took the initiative to send it, it was enough to block the mouth of Youyou.

No longer thinking about these messy things, after learning that Lin Wentao had made a hot air balloon, Xiao Ming suddenly came to his senses, and he asked Aster Beima to come to Bowen College.

In this battle to expel the barbarians, the Bowen Academy played a very important role, one was a hot air balloon, and the other was a lime bomb from Lu Tong.

When Niu Ben was in Shanhaiguan, he praised the lime shell, once this kind of shell explodes, it can instantly incapacitate a large area of the enemy, which is much more powerful than a simple gunpowder canister.

After this war, it has been proved that science and technology are the magic weapon for winning wars.

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

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

Seeing Xiao Ming coming, a group of students surrounded him, and Lin Wentao said, "Your Highness, this is the hydrogen balloon." ”

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

"How do you make hydrogen?" Xiao Ming attaches the most importance to this issue.

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 air balloon.

Speaking of this, Lin Wentao immediately became frowning, and he said to Xiao Ming: "This is thanks to the students of the School of Chemistry, they created hydrogen, otherwise this hydrogen balloon would not really appear." ”

Then Lin Wenyao pointed to the gourd-like clay pot behind him and said, "Your Highness, hydrogen gas came out of here and was filled into the air bag. ”

Xiao Ming had already noticed this thing.

Just by looking at the materials around this thing, he knew how the hydrogen was produced.

"Loser, how much sulfuric acid and scrap iron do you need?" Xiao Ming shook his head helplessly, but since he let them do it, it was inconvenient for him to be too harsh, so he only complained and asked the student standing on the side.

The student was from the School of Chemistry, and as he had guessed, they used hydrogen obtained by the reaction of sulfuric acid and scrap iron, and then let the hydrogen be inflated into the air bag through this instrument.

Looking at the excited faces of the students, Xiao Ming didn't want to spoil the fun, although the method was a little primitive, but the production of hydrogen was achieved step by step.

He said to Lin Wentao: "Yes, the hot air balloon has worked wonders in this war, in order to commend you, this king has prepared a knighthood reward for you, but this will wait for the generals of the Qingzhou Army to come back and reward them together." ”

"Your Highness!"

Lin Wentao and the other students smiled happily, they were rewarded for breaking the hot air balloon so desperately.

Xiao Ming smiled, it was time to reward some knighthoods to stimulate the students of Bowen Academy.

At present, Qingzhou's scientific and technological level is not a little worse than that of Europe, which requires Bowen College to catch up until it is fully surpassed.

After learning about the birth process of the first hydrogen balloon in Qingzhou, Xiao Ming asked Liang Yubin and He Cheng to manipulate the hydrogen balloon to take off, and he wanted to see what the difference in height between the hot air balloon and the hydrogen balloon was.

Liang Yubin and He Cheng also looked excited, now the two are a little obsessed with the driving of the heater, and now this hydrogen balloon makes them even more in love.

The two boarded the hydrogen balloon, and at this time, the people below also released the rope, and suddenly the hydrogen balloon lost its restraint and flew higher and higher.

"Your Highness, let's go." Liang Yubin and He Cheng looked excited, and their figures became more and more blurred in everyone's field of vision, until they became a small black dot.

"That's too high, isn't it?" Lin Wentao himself did not believe that the hydrogen balloon could fly to such a high place.

Xiao Ming nodded with satisfaction, "A hot air balloon is only a few hundred meters high, while a hydrogen balloon can fly thousands of meters high. ”

However, looking at the two people who were getting farther and farther away, Xiao Ming was a little worried.

The current hydrogen balloon technology is not complete, and he doesn't want the two of them to have an accident, but his worries are superfluous, and it didn't take long for the two of them to lower their altitude and soon return to Bowen College.

Seeing this, Xiao Ming breathed a sigh of relief in his heart, now he can take the hot air balloon to Chang'an with peace of mind, hoping that he can sell it for a good price at that time.
