Civil War Invasion

The planets are merging, the overlord dynasties, empires and alien races in human history will all come at the same time, evolve and die while alive. Well. The corpse may be used as snacks by other races. The protagonist is an ordinary wage earner, just because his talent is a little better than others. There is no harem, the girl affects me to draw the sword, there is no supernatural power, only basic attributes. This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
