The protagonist traveled from the earth to a different world and became the most powerful god. However, due to his inability to control the divine power, he went berserk and almost killed all the gods in the entire universe. In the end, he was forcibly sealed away by other gods for hundreds of billions of years. After hundreds of billions of years, the seal was finally lifted, but the protagonist turned into a little female dragon, and slowly regained the power of the god in the following days. (Note that the gender was changed from male to female, and there was no pretending to be a pig to eat the tiger. Even if he became a little female dragon, he was still very powerful, but every time he used his powerful strength, he had to pay a price)
