MTL - A War Between Spies - Chapter 21 violence

God gave me one more chance and finally came back after four hundred years.

As soon as I realized I returned, I decided that ‘no one should have pride.’

Long Fei, a cross-timer and doujin, is an otaku who traveled to another world. In the original world, he was an otaku fan of Gundam and military science fiction.
