Daqin: I Want to Be a Powerful Minister, but the First Emperor Actually Passed The Throne to Me

On the question of enlightenment, Liu Bang is still far from Zhao Yu. Zhao Yu has his own ideas. From the perspective of the Qin Dynasty, he belongs to the kind of epoch-making capable man!

"The words are so true, but how do we make these kites explode when they reach the sky in Ansi 19 Dalia?"

The size of each paper kite made by Zhang Niu is the same as the stove mouth that Qin Jun is using now, and it is smaller than Zhao Yu imagined.

Liu Bang said with a smile: "Master, I'm not stupid. Our Daqin 'artillery battalion' is most afraid of fire. Therefore, when the gunpowder encounters fire, it will explode with a 'bang'."

Zhao Yu's ingenious idea is how to effectively combine oil lamps with gunpowder. From the point of view of later generations, Zhao Yu expects to create a delayed explosion device, which must also be controllable.

"Okay, let me ask you again, let's tie the oil lamp and gunpowder together, so that the gunpowder can explode?" Zhao Yu looked at Liu Bang with a smile.

Zhao Yu took his oil lamp and asked Liu Bang, "I ask you, what do you think will happen to explosives when they catch fire?"

"Master, why are you frowning?" Zhang Niu asked on the road.

Zhao Yu thought about the whole set of equipment he was going to design, and his hair was almost white. It happened that Zhang Niu called, so he walked out of the tent and followed Zhang Niu to the depths of the Qin army camp.

That day, the rain stopped completely, but the wind didn't change at all. At noon, Zhang Niu came to Zhao Yu alone, "Sir, the paper kite is ready, please move over and take a look.

In fact, there are too many uncontrollable things. According to the technology currently mastered by the Qin state, although it is possible to create a time-delayed explosive device, the accuracy may not meet the requirements. Furthermore, in the current conditions of the Qin army camp Below, this one is difficult to do.

"This is indeed a problem!" Zhao Yu was agitated for a while, and he was not as thoughtful as Liu Bang, but he still decided to come this way.

"This is the question we will study next, my General Liu!" Zhao Yu said, "You look at the oil, there is a wick in the oil pot, and it will naturally catch fire. If we pour the oil out, the fire will burn. Add oil and the dynamite will explode!"

Liu Bang finally understood, he spread his hands and said with a smile: "Master, Liu Bang is not good at this, you can do it yourself.

"Master, let's estimate the wind force and see how many miles the kite can fly in an hour. Even if we can calculate it, if the wind direction changes, or the wind becomes stronger or smaller, have you thought about it?"

"Master, look, this is the paper kite I made!" Zhang Niu said, pointing to the things on a high platform made of wood in the open space in front of him, "This size is suitable, but the burden The weight of 20 pounds, if it is heavier, I am afraid it will not work, and it is necessary to continue to increase the size of the paper kite.

"Damn it, it's so easy to say!" Zhao Yu grabbed the armor on Liu Bang's chest and said, "Don't run away, we have to figure it out."

Zhang Niu also fell into 127 contemplation, this problem cannot be solved, because only manual operation can do this, and the precision is too high.

"I was thinking of hanging twenty catties of gunpowder under each kite, but I don't know how to make the gunpowder fly over the Roman city and fall."
