Xiu Jin, a high school student, accidentally got a ring, and incredible things happened one after another around him. The girl he fell in love with at first sight was his wife in his previous life. The wolf that was taller than the teaching building was his son and his deskmate. He finally met his second son, a snake bigger than a swimming pool. However, his son refused to recognize him. When he was in danger, he finally met his past life, but the result was to set off another Ragnarok. Sir, I know you were my previous life, but in this life I just want to be myself, and I want to use my own strength to protect the people around me. The god opposite gave me a meaningful smile, and made a bet, no matter whether they are gods or humans, please step away from me. My life is up to me.
