Lin Yue, an urban social worker, was sucked into a space-time rift by a strange purple-blue light group on a frustrated rainy night. When he woke up, he was in the back of Longhu Mountain and witnessed the fantasy scene of a Taoist killing the "evil rat". The ancestral jade pendant was broken into three petals, leaving only one piece close to the body, and the mysterious guidance of "guard the heart and protect the way, find the fragments and return them" still echoed in the ears.
He took off his suit and changed into a dungaree. From an ordinary person who was overwhelmed by reality, he unexpectedly broke into a strange world full of "Qi" and monsters. On the one hand, he has to adapt to the training life in Longhu Mountain and find the jade pendant fragments to find his way back; on the other hand, he will be involved in the conspiracy and cross-border crisis of the black organization in the subsequent collision with the world of Conan. This unexpected journey that began on a rainy night will eventually set him on a fantasy journey to protect both worlds.
