Zhu Xiaole, a good-for-nothing boy who was abandoned by his family, his biggest dream is to eat and die in the village. Until one day, a group of uninvited guests who called themselves "ancient beasts" lived in his Dantian - a green dragon who loved dramas, a phoenix who was obsessed with taking selfies, a Xuanwu who shouted to lose weight every day, and a Taotie who called himself "Ben Meow".
"Young man, you have a dull talent, but we are here to ensure that you run rampant in the world!"
"Wait, can you get out of my Dantian first?"
"No, the WiFi signal here is good."
From then on, Zhu Xiaole embarked on the bizarre path of cultivating immortality by being "forced to become stronger". While others rely on talent for cultivation, he relies on divine beasts to fight for him; others have to form a contract to control beasts, and his divine beasts bargain with him every day. In order to satisfy the bizarre demands of these "ancestors", he had to go deep into the forbidden land where demons roamed, and began a ridiculous adventure.
And when the evil demon army was pressing down on the area and everyone was waiting to die, Zhu Xiaole silently released the legions of mythical beasts playing mahjong in his Dantian.
"Everyone, let's discuss this - if you defeat the demon, I'll treat you to hot pot!"
