A cultivator transmigrates to the modern world, where a space-time turbulence destroys his body. The only way to survive is to seize the body of a young man named Zhong Jincheng. The modern young man graduated with a master's degree in philosophy five years ago but is still living off his parents. He comes from a single-parent family and quit his first job after entering the workforce because he was unhappy with it. He is a giant in thought and a dwarf in action, and his daily catchphrase is "Put knowledge into practice." When he realizes that his body has been possessed, he and the cultivator engage in a fierce struggle for control inside their shared mental space. The cultivator lost all his supernatural powers, spells, and spiritual soul in the space-time turbulence, leaving him no different from an ordinary person.
