Lin Mo, a modern emergency doctor, accidentally traveled to Chang'an City in the second year of Emperor Gaozong's reign in the Tang Dynasty. With his medical knowledge that transcended the times, he originally wanted to help the world by hanging the pot, but he was involved in the "Holy Cult of Star Tears"'s search for the secret of the "Fountain of Eternal Life", and therefore became the focus of the power game between the prince and the queen. Strange plagues occur frequently in the city of Chang'an. Behind the mysterious "punishment curse" and the "Hundred Ghosts Walking at Night" picture, there is a deadly conspiracy against the prince. In the whirlpool of power and life-and-death crisis, Lin Mo used medical skills to fight against deadly plagues and expose the "immortality" scam; on the other hand, he searched for the truth and the way to survive in the multiple cracks between the prince, the queen, the Persian priest and the enemy in the dark. Can his scalpel cut open the reality in this prosperous age?
