A Common Cheat in Another World Makes You the Strongest

Before the dead Kaito stood a god. It seemed he could be reincarnated. Apparently, he was given a cheat ability where he could acquire skills by points once he saw them used by others. Kaito wished for reincarnation, but he was reborn not as a human, but as a goblin. On top of that, he was in a weak position where he was exploited by humans. With the goal of returning to being human, he repeatedly acquires skills and evolves, growing to become the strongest in the world.
