Recently, Kavin got stuck, because I really can’t read it later. I plan to write about the development of weapons such as rail guns, which is divorced from reality. After all, there are only so many things I can write, and I’m afraid of harmony. I’m stuck recently. Sorry, sorry , If you don’t like to watch it, stop when you see this, really, I will write about some weapon research and development later. You can't kill the cherry sauce with one shot. . . . I'll try to see if I can write it.
