Art student Lin Zhou only wants to get by while running the tattoo parlor his grandfather left him, but he accidentally activates a guardian-spirit tattoo System hidden in an ancestral screen.
Other people's guardian spirits are mighty divine generals, ancient ferocious beasts, and peerless sword immortals.
Lin Zhou draws chibi Zhao Yun, a gluttonous young Taotie, and a zither spirit that keeps crashing.
As evil spirits breed in the shadows of the city and ancient seals gradually crumble, others overwhelm their foes with brute force. Lin Zhou can only pull out his tattoo needle and ask, "Hey, big guy, want a tattoo? I guarantee it'll make you strong."
And so the least reliable spirit-exorcism squad in history is born: a tattoo artist who talks a big game, an arrogant martial arts-obsessed girl, a gym student who only wants to eat, and a bunch of guardian spirits with wildly offbeat designs. Together, they save the world while falling behind on the rent.
