A single painting can make the attitude of the chief soldier change 180 degrees, and it seems so solemn that the soldiers around him are surprised and incredulous.

Lin Lie also looked at Lu Zhen a little dumbfounded, he really couldn't imagine that his county magistrate actually hid such a hand, and he didn't know what he had drawn, it had such a miraculous effect. However, he was still a little worried, if Lu Zhen couldn't give General Hu a satisfactory answer, he was afraid that their situation would still not be good.

Lu Zhen didn't have the slightest doubt, and immediately nodded and said: "Lord Chief Soldier, this thing is called an airship, and the lower pipe has already figured out the key points." As long as you give the subordinate a few days, and some patience and materials, you can make it. ”

"Really?" Hu Sui narrowed his eyes and asked as if confirmed.

"The lower officials don't dare to talk about this matter." Lu Zhen looked back into the other party's eyes.

A smile floated on Hu Sui's face, and he lowered the painting in his hand slightly, revealing a part, and then said, "That general soldier wants to see it." People, I give you as much as you want; I can also meet your requirements for other materials, you say, how long will it take to build this airship? ”

As a border general, Hu Sui still has a lot of knowledge, and he knows more clearly the natural law of standing tall and looking far. Judging from the artistic conception in Lu Jin's painting, the airship is dozens of feet away from the city, which is much higher than ordinary watchtowers and the like.

If there is really such a weapon in the Ming army, it will be much more convenient to defend the city in the future. As long as there are a few people guarding above, the movement from dozens of miles away can be controlled, and it is almost impossible for the Tartar to attack quietly.

The value of this airship is too great, even if he has always been steady, and people who are not happy and angry do not feel that they have some gains and losses because of this.

Lu Zhen heard the meaning of his words, obviously he wanted to preside over the construction of this airship himself, but there was no way to do it, so he nodded and agreed: "The subordinate will receive the order." In fact, the things needed for this airship are not too many and too expensive, only need ......"

He just wanted to say the material, but saw Hu Sui wave his hand: "Slow, you can follow me into the camp to talk in detail." With that, he stood up and walked into the barracks that originally belonged to Xiao Mo.

When Lu Jin saw it, he could only follow in step by step. At this moment, the expressions of the surrounding soldiers changed again, and no one expected that the chief soldier would attach so much importance to this matter, which made their curiosity about the airship mentioned by Lu Zhen even heavier.

In the barracks, Hu Sui had already spread the painting on several cases, and every time his eyes fell on the ball hanging high on the city wall, his heart would beat faster. It was so easy, Fang Cai pressed a little excited: "Lu County Order, can this thing really be suspended in the air without falling?" ”

"This thing is called an airship, and it can naturally fly in the sky. As for the reason, Xia Guan couldn't explain it in detail for a while. Lu Zhen said with confidence. In fact, what he gave was just a picture of a simple version of a hot air balloon, and it was a hot air balloon that could not fly casually.

For a liberal arts student, it is really sad to come to this era hundreds of years ago. Whether it's glass or perfume and other things that can make people make a lot of money, Lu Zhen doesn't know at all, the high school entrance exam was passed by cheating, how can he have the ability to create this compound?

As for muskets and artillery, as an ordinary citizen, he doesn't understand the mechanical principles, so as a traverser, he only seems to have a slight advantage in grasping the general direction of the future.

After searching his stomach for a long time, Lu Zhen thought of a thing that could be "invented" by himself - a hot air balloon. It was the easiest thing to make, hardly any technology, just a breakthrough in thinking.

The principle is also very simple, that is, the gas produced by combustion fills the ball sewn from cow and sheepskin, and then the ball is large enough to carry the basket under it and the people in the basket into the air.

Of course, the simplicity of the truth does not mean that today's people can figure it out, for the people of the Ming Dynasty, even if they have the idea of heaven, they only think that they are daydreaming.

When Lu Jin used the most plain words to tell what he needed and what he wanted, Hu Sui's face was even more joyful. At this moment, he had thrown all the unhappiness of Lu Jin's forced entry into the barracks, as well as offending him, causing Xiao Mo to be killed with a cane, and so on, and now he only cares about whether the airship can be successful.

"Good, the best craftsmen, the best cow and sheepskin...... I can give you anything, as long as you can create this flying thing for me within half a month, this general soldier will definitely ask the court for credit! In the end, Hu Sui, who was a little dizzy, waved his hand and said so.

"The subordinate officer takes the order." Lu Zhen exhaled, this time he made the right bet.

In fact, he also knew before that it would be a great risk to come directly to the barracks, after all, Xiao Mo was Hu Sui's subordinate, and he was far inferior in terms of proximity. So just in case, he drew such a thing a few days ago, in order to use it as a final talisman.

Now that this talisman has really worked, and let Mr. Hu make such a guarantee, it has finally not wasted his efforts.

However, this matter was not all in the hands of his Lu County Order, because then, Hu Sui gave an order, left him in the barracks, and specially opened up an area to house him and the craftsmen who were selected, and there was a circle of soldiers outside.

As a result, Lu Zhen was placed under house arrest, not only could he not return to the yamen, but he could not even leave the barracks. Moreover, he also knows one thing that Hu Zongbing can meet all his requirements, just because he can build an airship, if he fails to build things in the end, or if the things he creates are not as in the painting, then his Lu Jin's fate will be extremely miserable.

@@@@@

But in any case, things got up quickly. It just so happened that it was still the New Year's Festival recently, and the leather craftsmen in the county town were still idle, and as soon as the military camp gave the order, these people were quickly recruited in, and then these people began to get busy according to Lu Jin's instructions.

Lu Zhen is not good at hands, so when manufacturing and preparing these materials, he only plays a leading and lifting role, and more of those craftsmen explore on their own.

For example, the cow and sheepskin are nitrated, so as to make it more flexible; For example, what kind of cow and sheepskin is the toughest, after all, it is necessary to fill it with gas; Another example is how to sew these cow and sheep skins, so that they become completely integrated and impermeable......

If all this is left to Lu Zhen to do in person, even if he kills him, he can't do it. But with the collective wisdom and participation of these people, the process of making this hot air balloon seems to be very smooth.

Hu Sui gave him a half-month time limit, but it only took three days, and the huge round leather sphere, which was only one zhang and square round, had gradually taken shape, and a large bamboo basket was connected with hemp rope underneath.

It's just that as things take shape, Lin Lie, who was with Lu Jin, became more and more uneasy. No way, as an ordinary person hundreds of years ago, I couldn't believe that there was such a thing that could fly.

For people at this time, the idea of flying into the sky only exists in fantasy, that is the ability of the gods, they are just ordinary people, how can they do it?

So the more he could see the result, the more uneasy Lin Lie became, and finally took a moment, pulled Lu Zhen aside, and said with a serious expression: "My lord, is your idea really possible?" ”

Looking at the other party's shocked appearance, Lu Zhen just smiled slightly: "What, do you think I'm lying and fooling people?" ”

"But, can such a guy really go to heaven? That's ridiculous, isn't it? Lin Lie said, swallowed his saliva, and said boldly: "If the adults are really not sure, they are willing to escort the adults out of the barracks at night." As long as we return to the county office, General Hu will not dare to mess around. ”

Looking at Lin Lie's eyes that cared about him, Lu Zhen only felt a warm heart, the other party was really worried about his safety. And he also knew that what he said was good, even if he gave Hu Sui a few guts, he would not dare to lead troops to attack the county government, which would be tantamount to rebellion.

But even so, he had no intention of agreeing to the offer: "We don't have to flee to the county government. Don't worry, this airship will definitely go to the sky! ”

Looking at his confident appearance, Lin Lie was also a little in a trance. Could it be that what the adults said is true? Can this very simple ball made of leather really fly into the sky? However, no matter how he looked left and right, up and down, he really couldn't see that such a flat thing could have the ability to go to heaven.

Seeing that he still had suspicion in his eyes, Lu Zhen just smiled and patted him on the shoulder: "Just look at it, it won't take a few days to know that what I said is true!" ”

"Yes!" At this time, no matter how sure he was in his heart, Lin Lie could only choose to believe Lord Lu's words.

Time flies quickly, and the movements of the craftsmen's hands are not slow. By the thirteenth day of the first lunar month, everything had been completely made.

In the corner of the barracks where Lu Jin was, a large bamboo basket large enough to hold five people lay across the ground, and in front of it was a huge leather ball tied with a dozen or so arm-thick hemp ropes. It's just that the ball is still completely flattened, and I can't see any effect.

When the news reached Hu Sui, he immediately put aside everything else at hand and rushed over with his cronies full of hope. At the same time, the news spread in the barracks, and countless people were looking at the sky to see what this airship was......
