Chu Zhou, a close disciple of Medicine King Lu Jiuling, was ordered to guard the tomb for three years after his master's death. He was ridiculed by the entire Internet as a "grave-watcher" and was also divorced by his ex-fiancée, the Su family. After three years, he went down the mountain with half a jade pendant left by his master, a black iron token and a set of lost nine-turn rejuvenation needles. From rescuing people on the bus, breaking off the engagement at the wedding banquet, reviving the poisoned old lady Su with an injection, and then finally bowing to the old general in public, and the whole network kneeling down to beg him to come out of the mountain - only then did Chu Zhou realize that everything his master had left for him had been settled three years ago.
In the first volume, Chu Zhou broke into the Gu family building alone, rescued the twelve people who were treated as "blood-washing experiments" by Hades, retrieved the master's "Hundred Sketches", and took back the Renxintang. He also combined it with the Wen family's half-page sheepskin to form a map of the inner gate of the Shennong Tomb, which aroused the old grudge between his master and Wei Wuya, and paved the way for his return to Qingping Mountain.
