Chen Beichuan was suppressed by his status as a loser for twenty years. He was kicked out of his home and lived on the street. When he was about to die, he awakened to the sign-in system. Sign in in the toilet and get the "Nine Turns of Maoshan Taoism"; sign in in the mass grave and get "The Secret of Ten Thousand Ghosts Chaos"; sign in in the gambling house and get "The Art of Betting on Heaven"; sign in in the brothel and get "Yin Yang Joy Gong". The system says that this is only the most basic reward. The real rewards are in the secret realm of heaven and earth and the ancient ruins. From then on, while others practiced hard in seclusion, he found places all over the world to check in. The more outrageous the place, the more outrageous the reward. Until he successfully signed in at the origin of Heavenly Dao, the entire world of immortality went completely crazy.
