An ordinary office worker should have died in a traffic accident, but when he awoke, he became a goblin. Goblins have a lifespan of only seven days; however, our hero has been given the skill "80 Human Years" and takes advantage of his longevity by obtaining the skills of many goblins. He even meets the demon king who is on the verge of death and obtains his power. Now, he stands out in a different world.
Weakest race x strongest skill = the strongest, incomparable fantasy!
