Su Chen, a modern forensic doctor, turned out to be Shi Jian, the notorious law enforcement elder of the Maoshan sect when he opened his eyes. As the plot of "Mr. Zombie" comes to an end, the mystery of Mr. Ren's transformation into a dead body remains unsolved, and a new crisis has quietly arrived. He possesses the peerless cultivation of his original master, but he must always be wary of the "Erosion Evil Seed" planted in his body. He is also responsible for disciplining the mess of his playboy junior brother Shi Shaojian.
Starting from the claws of the zombies in Renjia Town, a series of mysterious cases followed one after another: the zombie family unearthed by the archaeological team, the evil spirit refined by the horse thief warlock, the bronze-armored corpse incarnated by the royal blood, the dark curse brought by the Western Count... Behind each incident, the same Yin Talisman imprint emerged. A man behind the scenes called the "Shadow Cult" is weaving a huge web that covers all ghosts in Kyushu.
Su Chen walks on the boundary between yin and yang with the rigor of a forensic doctor and the iron fist of a Taoist priest. He kills decisively and shows no mercy to evil spirits; he makes plans before acting, and uses modern thinking to dismantle ancient conspiracies. This is a righteous path destined to be lonely. Together with Uncle Jiu, Taoist Master Qianhe and others, he will spend his whole life practicing his vow of "fighting against good and evil for life." And when he finally uncovered the truth, he discovered that this murder that lasted for thousands of years was closely related to the blood of his body...
