"This person's name is Mo Wuji. Two years ago, he suddenly appeared in Heaven's Beyond Corridor. Because he killed from both the demon and human race, he was unable to find a place to stay. As a result, he went around Heaven's Beyond City Square, asking whether there were any shops for sale. Ostensibly, this person wasn't very clear about the Heaven's Beyond City Square's rules. Strangely, his pill house was actually purchased from an original shop owner called Mao Hu.
After Mao Hu sold his shop to Mo Wuji, the Cosmos Wall opened. Mo Wuji also went to the Cosmos Wall and he survived. He probably obtained many benefits from the Cosmos Wall because he entered secluded cultivation the moment he returned. He only opened his shop when he emerged from his seclusion." The person answering was Mifei Pill-Smith Pavilion's External Affairs Deacon, Wen Li.
