Rise of Armed Survival

The collapse of a superpower in another dimension brought about civil war, famine, and plague. God's chosen people once struggled on the verge of death, fighting each other for survival. When the original rich and handsome men were reduced to rubbish, a Chinese who traveled through time had to take up arms in order to survive. He gathered a group of people to grab territory and resources, and eventually became the king. Looking at a different war, everyone on that land must participate in the war if they want to survive. All the big countries are also involved in this war that carves up the corpses of the big countries. Maybe that war was not full of smoke but more thrilling.
