An ancient mirror passed down from a family connects the high-tech city and the ancient world.
Lin Xuan, a senior high school student, was originally a loser in martial arts, but he became the only "stowaway" who could travel freely between the two worlds.
In the real world, he hides his strength and pretends to be a pig to eat the tiger. His goal is to get into the top Wuhan University and get in touch with the truth about the blocked "Abyss".
In the prehistoric world, he reduced the dimensionality to attack, used scientific thinking to analyze Taoism, used the resources of cultivating immortals to feed martial arts, and gradually reached the top.
When the ultimate crisis of the two worlds converged because of him, Lin Xuan chose - the energy and blood in his left hand shook the nine heavens, and the magic in his right hand suppressed the abyss!
