There is a BUG, ​​please explain it.

Thanks to someone who pointed out that Yanyuan next to Tsinghua University during the Republic of China was actually Yanjing University, not Peking University. Peking University only moved from the Red Building to Yanyuan in 1952. This is my fault for not looking for this aspect. Information, I'm really sorry.

However, it does not affect the plot, and I am too lazy to modify it. From now on, Peking University will still be classified as Red Building, and Tsinghua University will be next door to Yanda University. Please forgive my laziness.

I recently bought a few second-hand books, roughly the basics of materials science, mechanical engineering, introduction to metallurgical engineering, principles and construction of automatic weapons, automatic weapon design, artillery design theory, artillery ballistics and projectile external ballistics, plus previous purchases Gunpowder and explosive engineering, emmm, some scalp numbness.

Apply what you learn and write as you learn.

Also, the plot is still not fast enough, there is no foundation, everything is empty talk.

Finally, there is one more thing to say. Due to well-known reasons, Yingjiu is currently unsearchable, but readers who have collected it and subscribed can watch it. Recently, I have been in a Muggle state. What the platform means is Modify, modify all main lines of content design, I...

I don’t know if Yingjiu can come out again, so that’s it for now.
