Shen Moyuan's soul was transformed into the abandoned son of a wealthy family. When he was kicked out of the house, he was accidentally bound to the "merit medical system". He must rescue his grandmother who was bewitched and possessed by evil spirits within 72 hours, otherwise he will lose all inheritance rights. As he investigated further, he discovered that there was an evil Feng Shui array hidden under the ancestral home of the Shen family, that his second uncle had colluded with the cult "Black Lotus", and that the poison in his grandmother's body was actually related to family secrets from twenty years ago. While he was using modern medical skills and Feng Shui secrets to save people and accumulate virtue, he was also unraveling the shady story of his family. When the system unlocked the "Thirty-Six Needles of Tiangang" and when the "Black Lotus Seal" awakened in grandma's body, Shen Moyuan realized that this was not only a seizure of family property, but also the ultimate game with a century-old evil.
