Mercenary War

Our MC Gao Yang is a military fan, a slightly ordinary military fan, loves knives, loves guns, and lastly loves adventure. Just to be able to play with real guns, the MC went to Africa, as a result he went down with a plane, resulting in a plane crash, from then on, only with a gun can be eat and survive, because he became a mercenary. What kind of height will our lovely military fan reach in the international mercenary community? Please do wait and see.
