Mortal's Mixed Penetration of Mysterious Bones

I knew on the first day of time travel—Master Xuan Gu's body was definitely not clean. It's not that his cultivation level has been sealed or his consciousness has been locked. It's about his past. How can an old demon with more than six hundred years of experience be clean? I thought it was just some bad things like killing people, setting fires, and robbing treasures. As a result, my memory was unlocked little by little, and I discovered—— This old guy has caused a lot more trouble than I thought. For example—— When he was young, he actually came to Tiannan. He owed someone his life and also took away a jade pendant. He has enemies all over the world, and people are looking for him all over the world. He seemed... To have met a certain big shot. (I don't dare to think about what kind of cultivation people have now.) On the other side of the Chaotic Star Sea, there was a group of people who were thinking about his cave. There was even a great demon in disguise who had an inexplicable bond with him. (It's a real bond, not that kind of bond... Right?) His treasures, his relics, his debts, his feelings—— It's all piled on me alone. OK. Come all come. I will slowly pay back six hundred years of cause and effect.
