Then he looked at Zhu Biao taking away the model made of bamboo tube and wooden stick in his hand.

"I call the grenade what your highness is holding. Of course, what you are holding now is just a model."

"The structure of this thing is very simple, for example, what you see is usually done. A bamboo tube plus a handle is enough."

"The hollow bamboo tube in the big head will be replaced with a cast iron shell in the future and fill it with gunpowder. Then fill it with gunpowder, add a lead, and finally add a handle, and then it's basically done."

"When it comes time to use, ignite the fuse, then throw it into the crowd. After the gunpowder explodes, it will directly blow the pig iron shell on the head. Then the broken shrapnel will kill the surrounding enemies."

Chu Ze's explanation was very fast, and Zhu Biao and others were not stupid either, so they easily understood what Chu Ze said.

But when Chu Ze finished explaining, the three of them looked at Chu Ze with an extremely strange look.

"A barrel, then fill it with gunpowder and add a lead. Isn't this a big firecracker?"

"How can this thing be used on the battlefield? It's not far away... You can't throw it away when you're close, and you'll explode yourself, right?"

"This sounds so simple!"

Looking at the three people who were disregarded, Chu Ze's mouth twitched slightly.

Especially Lan Yu's big firecracker was not allowed to be punished directly by Chu Ze.

"This thing...he mainly wins when producing and dealing with dense enemies."

"Indeed, the structure of this thing is very simple. And because I haven't created a detonator for the time being, I can only ignite the lead wire. If I want to use it, it has very high limitations."

"But... the original intention of my work was to facilitate Yongle to defend the city when he went abroad to build a city in the future."

"Think about it, when the enemy attacks the city, the man must be pressed up in a dense manner. If you stand on the city wall and throw this thing down, is it much more exciting than if you throw logs and rolling stones?"

"In the future, if you go abroad, it will be very simple to conquer a territory, but the difficulty is to defend the city."

"This thing is for you to use when you defend the city in the future."

"As for the battlefield, light cavalry speeds up the horse, create a fire trough, and keep the grenade lead longer. After you throw the grenade, you can just turn around and run away."

Hehe, what, let’s change the calculation method. Today’s calculation is the second chapter. This is easier to calculate, right?
