Chen Xiao is an ordinary delivery boy. The only thing that is extraordinary is that he has been able to see the "dirty things" wandering around the world since he was a child. This ability made him suffer a lot, and his greatest wish in life was to live an ordinary life.
Until a takeaway delivered to a haunted house attracts a life-threatening ghost; a mysterious talisman book "Netherworld Record" left by his grandmother awakens on its own at the critical moment of life and death, guiding him to draw a life-saving blood talisman. Since then, his ordinary life has been completely shattered, and the door to Yin and Yang has burst open.
Forced to inherit his ancestral legacy as a "traveler", he struggled to survive between the poisonous-tongued uncle and the gentle earth spirit. While clumsily learning to draw talismans to ward off evil spirits, he was dealing with a series of supernatural incidents under the neon lights of the city. Until the murder case of the "Ghost Bride" revealed the hidden evil conspiracy...
Holding the talisman pen in his hand, he no longer faced monsters and monsters, but his own fate. From a good-for-nothing who just wants to escape to a wanderer determined to protect one side, can he make it to the end on this road that shuttles between the yin and yang worlds?
