In addition, over the years, most of the weapon design drafts, various materials, and books left behind in Beicheng are in Russian.

Even some incorrect annotations that have similar pronunciation but completely different meanings can be eliminated by Si Yin while retaining the truth.

"Okay! Okay, with these drawings, our manufacturing speed will be greatly accelerated!"

Si Yin said excitedly, refusing to take his eyes off the drawing, and asked:

"I didn't get it. I got it from full dictation. I drew pictures and Li Xia noted the words."

Si Yin's expression suddenly fell and he threw the drawings on the table:
