During this period, Ma Lin inadvertently described firearms extensively in his lectures.
Everyone could see that he wanted to make guns.
Moreover, he already had the ability to produce the simplest guns, which were definitely more powerful than matchlocks.
Not only could he produce guns, but he could also produce cannons.
However, his cannonballs couldn't explode, they could only penetrate.
Other people's firecrackers could fly for a while before exploding.
Why couldn't his cannonballs do that?
Think it through carefully.
His cannonballs can also be made in the shape of rockets and divided into three sections.
The first section is used to launch the cannonball.
The second section is for separating the first and third sections, it is combustible, but burns relatively slowly.
The third section is the explosive part.
The first and third sections are relatively easy to make.
How should the second section be designed?
