The Max-Level Celestial Master Loves Pretending to Be a Pitiful Little Green Tea

A group of celestial masters pried open the coffin of a vengeful ghost who had slept for a thousand years. Before Lan Mian could make a move, someone held out a marriage contract to her. Lan Mian slowly managed a single: “?” The marriage contract couldn't be undone anytime soon, so she had no choice but to become bound to a dying young man. It was a hassle, but fortunately, it wouldn't be difficult. Once the young man had lived out his century, Lan Mian could go back to sleeping. But before then, she needed to deal with the little ghosts she'd left behind a thousand years ago. A mysterious celestial master always dealt with the little ghosts before she could. Lan Mian didn't understand, but she was pleased. After all, the less she had to do herself, the less trouble she'd face. After being beaten to it yet again, Lan Mian tidied up and prepared to go home to eat the fermented-rice dumplings her young man had made. But the celestial master who had arrived late blocked her way. He shouted that he would exorcise her, and even called over that mysterious celestial master. Lan Mian rolled up her sleeves, ready to fight, then froze. Why was the mysterious celestial master summoned by the Celestial Masters' Sect her own gentle, devoted young man?
