A Mercenary's War

Gao Yang is a military enthusiast, an ordinary one who loves knives, guns, and adventure.

By accident, Gao Yang ran off to Africa, only to encounter an air crash. By luck he survived, but from then on he could only make a living under the gun barrel, because he became a mercenary.

How high can a military enthusiast rise in the international mercenary world?

Please look forward to it.
