The Legend of Sumai

Late at night, in the underground alchemy room of Yinxia Temple, the fire illuminated a struggling face. Lu Shouxin didn't know that the "heart-protecting pill" he took contained a poison called heart-eating grass. He also didn't know that the golden light from his heart that saved his life was, in the eyes of his master Yun Yinzi, a rare opportunity in a thousand years and the final ingredient for refining the "Nine Transformations of Life-Reversing Pill". He didn't even know that in a pawn shop three hundred miles away in Heishui City, his mother, Su Wanzhen, was giving him thirty years of life in exchange for a glimmer of hope. The road to immortality is long and the human heart is fragile. There is never black and white between good and evil in this world, there are only intertwined shadows in the sun and the undying light in the shadows.
