I Was the Weakest and Defeated God

This is a world of swords and magic. Human beings have been fighting for hundreds of years, and are finally punished by the gods who claim to be the creator! Millions of monsters flooded the earth, thirteen countries were instantly defeated, and only 5% of the world's total population remained. The remaining humans had to come to the northernmost part of the earth - the Canadian forest to survive. People built a 50-meter-high wall to resist the invasion of monsters. It wasn't until a hundred years later that the male protagonist was born. . . . . This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
