Earth Vein Guide

My grandfather Chen Shouyi played the fool his whole life in Chenjiawa. The villagers called him 'Old Wilty.' He farmed, went to market, sat on the doorstep rubbing mud, never quarreled with anyone, and lived as the most worthless man in their eyes. On his deathbed, he gave me a bronze plaque engraved with the characters 'Zhi Mi' (Guide to the Lost) and three volumes of ancient, tattered books. 'Earth Vein Guide,' passed down since the Yongle era of the Ming Dynasty, now six hundred years old. He left only one last word: The Chen family, generation after generation, single inheritance, guarding one path. With this bronze plaque, I was admitted to Beining University of Technology, but accidentally uncovered a shocking secret—the school was built on top of a mass grave from 1937, with four main buildings precisely pressing down on the four cardinal array points, underground malevolent energy surging, about to burst forth. I wanted to follow my grandfather's example of hiding my talents and enduring, but my roommates encountered evil one after another, and things spiraled out of control. I could no longer stand by. Only then did I realize that my grandfather was never truly weak. His half-life of humiliation was merely to evade an enemy that had haunted the Chen family for six hundred years.
