[Mysticism + Mystery Solving + No Romance + Revenge] Su Nian, a palace maid who died a gruesome death outside the palace in her previous life, was reborn in the deep palace at the age of twenty-two. A temperamental mahjong spirit popped out of the jade pendant she carried and granted her a remarkable gift: by drawing tiles, she could hear people's thoughts, at the cost of shortening her life and draining her vital energy. She used this mystical ability to see through the palace's schemes and cut down anyone who reached for her. By day, she pretended to be a frail palace maid. By night, she practiced martial arts, gathered herbs, and accumulated merit. By chance, she met Shen Yanzhi, an official of the Court of Judicial Review. He investigated cases openly while she secretly probed people's minds. Together, they pursued the real culprit behind her murder in her previous life. The deeper they dug, the more they uncovered, eventually exposing a secret channel for smuggling treasures that had been entrenched in the palace for years. When the day came for her to leave the palace, Su Nian opened a modern mahjong parlor. In public, she played tiles and drank tea; in secret, she gathered intelligence and solved cases. In her previous life, she died in an alley no one cared about. In this life, she would cultivate immortality while playing mahjong, and live a life of comfort and joy.
