"Get up, get up......" Li Zubai finally saw his hard work, the hot air balloon went up, he couldn't help it, and shouted.

In fact, Yang Reform's gaze has never left the hot air balloon. Seeing that this hot air balloon is really moving, it is rising, and I know that this hot air balloon is indeed a success.

"Hehe, indeed, Master Li, the hot air balloon did succeed, I saw it, it's amazing! I didn't expect that this paper and heat can also hold people up, it's really unimaginable! Although Yang Reform is a person of the 21st century, he has seen not only hot air balloons in the sky, but also airplanes and rockets, but in the Ming Dynasty nearly 400 years ago, he saw people fly up with a hot air balloon made of paper paste, and he had to sigh.

Including Wang Chengen, some "bodyguards" also exclaimed, looking blankly at this "monster" that can take off into the air, what is this? Actually being able to take people up, doesn't this mean that people can fly to the sky? Such a huge thunderbolt exploded above his head, and what he had always believed in his heart showed signs of collapse.

After the hot air balloon was raised, the speed of the rise was much faster, and in a short time, the hot air balloon was close to two-thirds of the height of the stargazing platform, Yang Reform took a general look, this thing seemed to be made of paper paste, tied with hemp rope to a frame made of bamboo, and there was a person standing inside, and when he saw Li Zubai's side, he didn't say much, just knelt down and kowtowed in the direction of Yang Reform, which was considered a salute, a little far away, and did not speak.

Look at it again, the bottom of the bamboo basket is tied with a hemp rope, and now, this hemp rope has been stretched straight, and the height will not rise again.

The person standing in the bamboo basket looked only about twenty years old, very young, his expression was not panicked, he was busy in an orderly manner, and he looked calm. In the middle of the bamboo basket, there is a stove, and this person is adding firewood to the stove and lighting the fire.

"Papapa......" Yang Gai couldn't help but clap his hands, this time, the hot air balloon manned experiment was a success, and it can be regarded as an expression of admiration for the spirit of the person in the bamboo basket.

"Lord Li, this hot air balloon is really a success! Tell me what you made this hot air balloon out of. Yang Reform is also very happy, this hot air balloon can have a huge impact on the end of the Ming Dynasty, and he will definitely build momentum for this hot air balloon to achieve the purpose of shocking people, so that this pool of stagnant water like the end of the Ming Dynasty will stir up a lot of splashes.

"Hui Gongzi, this hot air balloon, which is made of bamboo strips and fishing nets, is pasted with paper layer by layer inside and outside, hanging with hemp rope below, and below is a bamboo frame, in the bamboo basket, there is a stove, and the chimney in the stove is connected to the heat, and the firewood is burned...... Li Zubai explained in detail the structure of his hot air balloon.

Yang Reform is speechless, the materials and manufacturing process of this hot air balloon are really simple enough, this quality, can only be described in one word, that is, inferior, and then look at the production materials, they are all flammable materials, if this accidentally catches fire, this hot air balloon will become a big fireball.

"Lord Li, your hot air balloon seems to be made of flammable materials! If you're not careful, you'll get up! You should pay attention to this. Yang Gengai asked about what he was most worried about. If on the day of the performance, in front of millions of people, this hot air balloon turns into a big fireball, the effect is ...... I really can't say it, don't say that it shocked the people of the Ming Dynasty, the people of the Ming Dynasty will give themselves a vivid lesson in "superstition".

"Hui Gongzi, this hot air balloon, indeed, the materials used can't withstand the heat, this paper ball, before use, must be sprayed with water, and then dry it slightly, because when the hot air is poured into it, the paper ball will be gradually dried, and the paper ball will become hotter and hotter, so you must take advantage of the paper ball before it dries thoroughly, or before the green smoke comes out, quickly extinguish the fire in the furnace, otherwise, this paper ball, ironclad will be burned, even so, this paper ball, not many times, will have to re-paste the paper ball......" Li Zubai talked about some of the processes of this experiment.

When Yang Gengai heard this, he only felt two words, that is, horror, this kind of super unsafe thing, and he dared to use it to carry people, but it was this most humble thing, but it was the most advanced, advanced, and scientific thing in this era. "And then? Or didn't fall before it smoked? By the way, why don't you make your hot air balloon with silk? Yang Reform suddenly came out with a sentence, because Yang Reform suddenly remembered that this hot air balloon, in later generations, is said to be made of silk.

With silk? Li Zubai was shocked by the emperor's words, this hot air balloon, he burned no less than dozens, if he used silk instead of paper, Li Zubai felt, how could this be like a pile of silver burning! Confused, burning money, this is simply burning money!

"Hui Gongzi, if this doesn't fall before it smokes, most of this ball will be lost, I'm afraid it will burn down,...... Several balls have already been burned in the next ......, as for making hot air balloons out of silk, maybe it's okay, maybe it's okay...... this, try it, try it, try it......" Li Zubai said here, and he also seemed to have palpitations, and also frightened the emperor by the idea of being fearless and willing to burn money.

It seems that engaging in science in ancient times was also a high-risk thing! Without the guidance of theory, it is really difficult to explore with experience. Yang reformed felt that this kind of spirit could be summed up in the Gods and Demons Laboratory.

"Did you hurt anyone?"

"Hui Gongzi, this is not true, every time someone rides, they are cautious in the next, and the fire time is not more than a quarter and a half, so, as long as it is according to this time, the hot air balloon will basically not be a problem, so I dare to invite the son to come and see, otherwise, in the case of not being sure, how can there be such a big courage there?" Li Zubai said here, and became confident again, this kind of thing that can lead people to heaven is made from his own hands, this is enough to be recorded in the history of the Ming Dynasty, this is enough to leave a mark in history, and he can indeed be proud.

"Well, this, it's not bad, Lord Li can be so careful, right, and it is also worth affirming, when you do experiments in the future, you will have to do this, by the way, Lord Li, I am going to let you perform this hot air balloon manned performance in public, I don't know if you can do it? Are you sure? "Using a hot air balloon to do a public show, this, is the purpose of the hot air balloon, if you can't do this, then the hot air balloon is useless, the hot air balloon also has an ultimate purpose, that is, military, this, for the time being, there is no need to tell others.

Li Zubai struggled for a while, but still told the truth honestly, and said: "Hui Gongzi, at present, I can only tie it with a rope, and take off in the absence of wind, once there is wind, this, the hot air balloon under it really can't control the direction, this, I'm afraid it will float around with the wind, in case, float to the place where it shouldn't go, this, or, the time to make a fire is too long, I'm afraid there is no certainty, what I can be sure of now is just to be able to safely lift off into the air, three or four feet above the ground......" Li Zubai didn't dare to deceive the emperor, Tell the truth honestly.

Yang Gai didn't blame him, and said, "Then you haven't done an experiment of floating with the wind under windy conditions?" ”

Li Zubai thought about the emperor's words for a while, and said, "Hui Gongzi, this, there is really no place for the small one, this drifts with the wind, it needs a very open place to keep rising into the air, constantly groping, to see how the ball will float, where it will float, how far it will float, and it must be hidden from people's eyes and ears, and when burning balloons in this stargazing platform, they are all cautious, for fear of being seen, and they dare not rise, for fear of being seen and said to be a monster, for fear of frightening people...... Li Zubai also explained his difficulties.

"This, it's really a problem, so let's find a wide, sparsely populated place for you, you take people to do the hot air balloon drifting experiment, be sure to figure out the various data of the hot air balloon liftoff, especially the impact of wind speed on the hot air balloon, figure out the longest liftoff time of the hot air balloon, the limit of the lift-off time, be sure to ensure that you can safely do a flight performance in public, the flight time of the performance is not long, that is, one or two moments of time is enough, I can give you the experimental time, Not too much, a month or two, how? Can you do it? Yang Gengai decided to vigorously support Li Zubai's "scientific research" and decided to make an open air show.

Li Zubai hesitated, this time is too urgent, not enough time, not enough manpower, and more deadly, which may require a lot of silver, the emperor asked him to burn money, use silk to make hot air balloons, he felt, in the absence of enough silver, he did not dare to promise the emperor anything, Li Zubai felt that this silk was too much money, and he didn't have a lot of silver, and it was not good to ask the emperor to ask for it, so he could only say why.

Yang Gengai saw that Li Zubai was very hesitant, and said: "Don't worry, do things for me, I will never treat him badly, in this way, your expenses, I have paid for it, first take 5,000 taels as expenses, if it is not enough, then ask me if it is, in addition, send you a hundred households, one as a security guard, to protect your safety, to drive people close to the experimental field, and second, to be driven by labor, to assist you in the experiment, how about it?" "Yang Reform can be regarded as a heavy bet, we must get this hot air balloon out, we must shock the people of the Ming Dynasty fiercely, let these people open their eyes to see the world, don't bury their heads under their buttocks, and more importantly, in the military as a secret weapon to deal with the likes of wild boar skins, no matter how much money is spent, if these thousands of taels can be made, it can only be said that it is worth it.

Li Zubai this time, did not hesitate much, not only rich, but also bodyguards and labor, can be regarded as the emperor's full support, if he does not appreciate it, then the emperor will be disappointed in himself, the most important thing is that Li Zubai is confident in his hot air balloon, enthusiastic about the research of manned hot air balloons, and enthusiastic about his future. Li Zubai no longer has any psychological barriers to burning money, he thinks, burning money will burn money, Huang Yanjing let himself burn money, what are he afraid of? I heard that the emperor has a lot of money, so I don't have to worry about burning a little for the emperor, anyway, the emperor is rich all over the world.

"Back to Your Majesty, Weichen will definitely do his best to do this for Your Majesty and never disappoint Your Majesty's expectations." Li Zubai is no longer ambiguous, and he is full of hope for this "money-burning project".

"Well, that's good, I know, this hot air balloon manned flight, it is absolutely feasible, in addition, I will give you a few more suggestions, first, don't be afraid of failure, don't be afraid of burning the hot air balloon, burn one, make another one, burn two, do him four, to explore this hot air balloon clearly, second, all kinds of data of this hot air balloon, can not just stay in your mind, you have to see the paper, write all the data on the paper one by one, and then comprehensive statistics, in this way, you should be able to get a relatively stable value, and, You're blindly groping with experience,...... How to say, now is a last resort, you not only have to experiment how to fly a hot air balloon, but also to find out the truth, for example, why this hot air balloon can fly? How big do you have to build a hot air balloon to fly? How much does it increase, how much weight can it carry, in the air, the impact of wind speed on the hot air balloon, this is to say, not only to know it, but also to know why, only to figure out the principle, the improvement of your hot air balloon, there is a theory to rely on, otherwise, your hot air balloon will never be able to surpass your current level, will always be a flammable and explosive thing, understand? Yang reformed a lot of wordy words, and basically said his understanding of hot air balloons. I hope that this Li Zubai will not let himself down, and it is best to study the buoyancy of the air, this kind of "black technology" thing.

Li Zubai listened to the words of His Majesty the Emperor, listened to it like a dream, this emperor, as if he knew more than him, the actual author, pointed out the direction to him, let him have a lot of ambiguity about this hot air balloon, suddenly enlightened, immediately knelt on the ground, said: "Your Majesty is empowered, Weichen is grateful, and he is infinitely useful." Weichen has written down His Majesty's words, and he must do what His Majesty says. ”

Yang Gai nodded, that's all he can do with the hot air balloon, this hot air balloon, no matter what, he has to do it, he wants to use this hot air balloon to shock all the people of the Ming Dynasty, and to lift the haze that covers the time and space at the end of the Ming Dynasty.

"Well, it's good, you can understand, it's good, and you haven't lived up to my expectations, do a good job, and when the performance in the sky is successful, I will let you go to the bureau, there, it should be very suitable for you." Yang Reform is ready to recruit a group of talents for his "Academy of Sciences", and this Li Zubai can be regarded as the top "scientist" of this era, which is worth cultivating.

History? Li Zubai has never heard of this kind of institution in the imperial court, but he also guessed some from the name, probably related to this calendar, the calendar has always been the top priority of the imperial court, and there will definitely be important ministers of the imperial court.

Wechen obeyed. Remember Your Majesty's teachings. Li Zubai kowtowed again.

As he spoke, the time for the hot air balloon to take off was approaching, and the person standing in the hot air balloon began to remove the firewood, and the hot air balloon was tied with a rope and began to slowly descend in place.

After Yang Gengai watched the launch of the hot air balloon, he didn't stop much, and went straight down the stargazing platform, and he had to go to Guozijian.

When I went down to the bottom of the stargazing platform, I saw that there were many people kneeling outside, none of them were of very high grade, and the leader was a cyan official robe.

The one who led the way saw the emperor coming out of the stargazing platform, and immediately shouted: "Chen Qin Tianjian Zheng Li Tianjing knocks on my emperor long live long live long live." ”

His own deeds were revealed. Yang Gai took a look at this Qin Tianjian supervisor, and he didn't take it too seriously, in this Qin Tianjian, many people have seen him, and when he came here, it is estimated that it is difficult to completely ignore and be unaware.

"It's all exempt, it's not in the palace, it's not like that, besides, don't talk about today's events, understand?"

"Thank you, Lord Longen, and remember Your Majesty's holy message." Li Tianjing, the supervisor of Qintian, took the lead and stood up.

"Well, that's good, there are a lot of good things in your Qin Heavenly Prison! There are also a lot of talents! Not bad, not bad, well done, well done! After Yang Reform said these words, he left in a hurry. His stomach was growling with hunger, and he had to find a place to eat.

The officials of Qin Tianjian were still immersed in the great happiness of meeting the emperor, who knew that the emperor would leave behind such a few headless words, so they began to ponder. There are a lot of good things in Qin Tianjian? Is it a hot air balloon? Only this, I'm afraid that the emperor can come to the official prison of Qin Tianjian, there are a lot of talents? It must be Li Zubai's guy who smokes from the ancestral grave, no! There are a lot of good things and a lot of talents, this is not just a person, could it be that Your Majesty is saying that in the Qintian Prison, what Li Zubai can do, we can also do? …… Isn't that a group of people surrounded by a great sense of happiness? Everyone's ancestral grave can smoke from it?

The gratitude of Li Tianjing, the supervisor of Qintian, and the call to send His Majesty the Emperor interrupted the dreams of these people, and they knelt down one by one to see the emperor off.

Yang Gengai got into the carriage and lay down, only then did he feel comfortable, for half a day, he had been standing, he was really tired, and his waist and legs were a little painful. Although the shock absorber of this carriage is not good, it has a lot of cushions, and it is not yet to the point of riding a tractor.

Yang Gengai lifted the curtain of the carriage and said to Wang Chengen, who was following outside: "Big companion, today's matter, you remember, the Zhang Baihu who guarded the city, I think it's good, you let people pay attention to it, investigate his background, and then let him go to Master Sun's new army training camp to report, train for a few months, come out, be promoted to an official, give a thousand households, or a deputy thousand households or something, continue to defend the city, maybe you can ......use it later" Yang Reform felt good about that Zhang Weiyi, and felt that his own strategy for defending the city was in the future, Maybe you can use him, and I'm going to train it.

(To be continued)
