Ahhhhhh, it's really beautiful (amusing myself...)

The author's writing is beautiful, I like it very much, the writing is very exciting, and it made my blood boil. (The author should update quickly!!! The update is too slow to read!)

So beautiful (hi) Score a point No more pressure, no more pressure (sad

To be honest, if it doesn't work, the author can just go to Huixing to write. The restrictions there are not that big.

Come on✊I like this book very much

Except for the poor details and immature writing that makes people think too well, everything else is okay. I am very curious about how black powder is used to produce a water-cooled machine gun, because the machine gun must first produce nitrocellulose. In fact, metal fixed-loading ammunition also contains black powder and smokeless powder. For farming development, electricity can be used first and then gas. If there is electricity, you can use electroplating and electrolysis. The enemy is a cold weapon. You can forge armor plates and sew them on the carrying equipment to prevent sword stabs [Chigua]

Come on, the author hasn't read such a popular book in a long time.
