After opening the copper pill, Shao Xi was surprised to find that there was a wax pill inside, and it seemed that he had considered moisture-proof, waterproof and even mildew-proof when he collected this object.

Shao Xi didn't crush the wax pill directly, because he had heard before that some skilled craftsmen would have some last anti-theft methods in order to prevent secrets from being stolen by outsiders.

It is very likely that there is something poisonous and sharp hidden in this wax pill, and even if someone gets it, when they crush the wax pill, they will be highly poisoned, so that the secrets hidden in the wax pill will not be leaked.

Shao Xi reached out and took the teacup next to him, and smashed the wax pill with the bottom of the cup little by little. As expected, there are dense and thin short needles like cow's hair hidden in the wax pills, which should be inserted into the wax pills one by one while the wax pills are not completely cool, and finally a thin layer of wax is applied to the outside of the wax pills.

If you had crushed this wax pill directly with your hands just now, it would be very likely that your fingers had been punctured by a short needle and injured by the poison on the needle.

Lao Wu, who was watching from the sidelines, couldn't help but shake his head, sighing that fortunately Shao Xi was careful enough, otherwise he might be in big trouble.

Shao Xi pulled out his silver short knife from his boots, and little by little pulled away the crushed wax pieces and those short needles, revealing the oiled paper bag inside.

Putting away the short knife, he carefully opened the oiled paper bag and took out a small piece of cloth from it.

Shao Xi asked Lao Wu to clean up the things on the tea case, and then spread the cloth on top of the tea case. Lao Wu poked his head over, looked at the strange pattern drawn on the cloth, and asked Shao Xi for some reason: "This doesn't look like a map, but like a pattern of making something, but I really can't understand what it is, can you understand it?" Shao Xi lowered his head and looked at it seriously for a while, and he couldn't help laughing, startling Lao Wu, who was concentrating on the pattern.

"Don't look like you're taking the wrong medicine, what makes you happy like this? Why does I look like a piece of furniture? Is there anything special about this thing? ”

"This thing is nothing to me, but it is indeed a rare thing for others, no wonder Boss Ruan wanted to hide this pattern back then, if this thing is obtained by someone with a heart, it is really a great thing.

"Do you remember the gunpowder I made on the prairie? Although this thing is not the same as gunpowder, if it is used in the battle between the two armies, it can indeed become the key to reversing the situation. When Shao Xi made gunpowder in the grassland to help the Toth Department win the tribal war, although he was not present at the time, but when he returned to the grassland, everyone in the Toth Department had told him about it.

Just listening to these people's stories, Lao Wu knew how terrifying the thing called gunpowder that Shao Xi made was!

Now Shao Xi actually said that the thing researched by Boss Ruan can be compared with the gunpowder he made back then, which is enough to prove how shocking the thing Boss Ruan painted in this pattern!

It is no wonder that the Ruan family was wiped out at the beginning, and Ruan Haoyang would be hunted down for several years. It seems that this thing will play a key role in the war situation, but Shao Xi seems to be quite familiar with this thing, and even a little strange.

Could it be that this kid had seen this before? I don't think so!

"Don't sell it, if you have something to say, let it go! I don't have time to guess with you here, old man! What the hell is this? You actually say that it can be compared to the gunpowder you made, is this thing also a weapon for killing? ”

“Nonono！ This one is different from the gunpowder I made, which was used for killing, but this one has more uses. As he spoke, Shao Xi tapped the top row of words on the cloth with his hand, and continued: "Didn't you see it? Boss Ruan named this thing an Soaring Kite, and you know what it's used for from the name, but I personally prefer to call it a glider. "Shao Xi's one

"Nonono" Lao Wu didn't understand what it meant, but the word "Soaring" knew from a literal understanding that it was something that could fly in the sky.

Since it is called a kite, it not only means a flying bird, but also refers to a kite that can be flown off. But Lao Wu still doesn't understand why the pattern of a kite makes so many people rush to fight for your life?

Is there any difference between this thing and a normal kite? What's so special about it? Shao Xi looked at Lao Wu's puzzled expression, and smiled a little proudly, after all, these have already involved Lao Wu's knowledge blind spots, and it is a good time for him to pretend to be forced.

So Shao Xi put on an unfathomable expression, and said a little sarcastically: "If I tell you anything about air lift, air resistance, aerodynamic effect, air flow effect, and gravity effect, I guess you won't understand it, so I'll tell you about it briefly!" Lao Wu was confused by Shao Xi's bunch of professional terms, how had he heard of this?

Since Shao Xi said that he wanted to talk to him simply, of course, the simpler the better, otherwise it would be too brain-burning.

"Don't talk nonsense, pick something I can understand, what the hell is this thing for?"

"You should know all about wooden kites, bamboo kites, and paper kites, right? It's pretty much the same as those things, but it's very different. Lao Wu looked disappreciative after hearing this, and even said with some interest: "Isn't that just a kite?" What's so strange? Shao Xi shook his head with a smile and began to patiently explain to Lao Wu: "How big can those kites you know be?" The largest one is only three or five feet, and the kite made by Boss Ruan is a few feet!

"And it's not just flying, it's being able to take people into the air with them, and it can be manipulated in the air, so that people can soar through the air with the help of this thing.

"Even a martial arts master who has cultivated to the pinnacle of the realm of perfection can't stay in the air for a long time, but this thing can make people fly in the sky all the time, don't you think it's amazing?" Lao Wu's eyes widened, as if what Shao Xi said made him feel unbelievable.

"This thing can make people who have never cultivated the Dharma fly in the sky all the time? Wouldn't those of us who have cultivated the Dharma all our lives cultivate in vain? With this thing, wouldn't you go wherever you wanted, and no one would be able to catch it? Shao Xi looked at Lao Wu's fussy expression, and couldn't help but be happy again.

It is said that technology changes cognition, and it seems that Lao Wu's cognition can be improved to a certain extent today, and he finally knows that some people don't need to cultivate their body when they fly to the sky.

But how did this old guy think of the first thing that no one else could catch when he ran away? He's really a thief!

"Indeed, as you said, even if you have not cultivated the body method, you can fly in the sky for a long time, but the prerequisites are also very harsh, and it is not just a kite that can take people to the sky, and its overall shape requirements are still very high.

Judging from the drawings drawn by Boss Ruan, it seems that the problem of shape has been solved, but the control of the object's flying and flying attitude in the air is not perfect enough, and it is not enough to bring people to the sky.

"The important thing is how to manipulate this thing in the air so that it can fly freely according to human wishes, and his pattern still needs to be improved, and it seems that only I have done it."

"What? You're going to get this stuff too? Lao Wu looked at Shao Xi like a monster, this kid grew up watching him since he was a child, how could it seem that he had never heard of many things he knew?

Where the hell did he learn it? When I heard that he was making gunpowder on the grassland, it made Lao Wu feel incredible, and now he can even see the problem with the things that Boss Ruan has worked hard to create, and even modify it himself, what is this not a monster?

Others are desperately fighting for things, but he can lightly point out that this is not good, there is not right, where did this kid learn these things?

At this time, Lao Wu felt that Shao Xi in front of him made him more and more incomprehensible. Shao Xi's martial arts talent is extremely high, and he has made rapid progress in martial arts cultivation, and Lao Wu can understand it, but where did he get his knowledge in this strange skill?

Looking at Lao Wu's eyes as if looking at a monster, Shao Xi was also helpless for a while. There are some things that you really can't explain to this old fellow, and you can't tell him that you're from another world, right?

It can only be made up of some nonsense to fool him, so that he will not be cranky again.

"Don't look at me like that, master, I am talented, full of learning, full of whimsical ideas, you old guy naturally can't understand, in your eyes I think it's amazing, in my lord, I'm just handy, can you not make such a fuss?" Lao Wu shook his head and teased Shao Xi: "Don't think that you know some things from the sidelines!" Even if this thing can send people to heaven, what is the use? A person who has not practiced martial arts is just a useless person even if he floats in the sky, so what is the point of bringing people to the sky? Shao Xi looked at Lao Wu with sympathetic eyes, this is the cognitive difference caused by the huge information gap, if he didn't see many things with his own eyes, I'm afraid he wouldn't believe it.

But since he asked himself, whether he believed it or not, he still had to explain it to him.

"You don't understand this, if someone can fly in the sky to see the overall situation when the two armies are facing each other, and have a full view of the movement of troops and horses on both sides, wouldn't it be equivalent to completely controlling the battle situation in their own hands? How can it be said that those who fly in the sky are useless? Although Lao Wu didn't know how to lead troops to fight, Shao Xi said it was simple and clear, easy to understand, and Lao Wu immediately felt that Shao Xi was reasonable.

If this thing is used on the battlefield, it can indeed play a role in controlling the overall situation. In fact, Shao Xi hadn't told him that this thing could be used as a bomber in addition to being used as a reconnaissance aircraft.

On the ancient battlefield, the appearance of bombers is not too cool!
