Lin Xiaotian was ignored by fate since he was a child. He grew up between humor and ridicule, relying on his open-mindedness and wit to defeat monsters and level up. An accidental farce led him to enter the gate of cultivating immortals by mistake, and met the mysterious girl Yu Xiaoxian, the honest brother Guo Erdan, the poisonous wise man Hua Yueyue and the naughty mythical beast Bai Lalanlan. The five-member team encountered many adventures along the way, including daily life and death, as well as life-and-death tests. In the midst of machinations and disasters, fate and choices, they stick to their friendship and grow with each other. Finally, relying on their invincible mentality of "breaking the situation with laughter", they break the shackles of the old world and become new heroes who save all sentient beings. The story is humorous and compact, with ups and downs, reflecting the power of growth and friendship, and running through the attitude of "even if your fate is unfortunate, you must face life with a smile".
