Lin Bufan was originally an ordinary boy from a small mountain village. Due to an accident, he got involved in the struggle between immortals and obtained a secret book of cultivating immortals that seemed useless but actually had miraculous effects. Accompanied by his good friend Fat San'er, the sharp-tongued spirit fox Su Xiaoli, and the naturally aloof Lu Qingyi, he stirred up troubles in the Three Realms. The protagonist group gets into trouble along the way, not only getting acquainted with all kinds of weirdos, but also using jokes to avert danger in the confrontation between good and evil and the competition for power. As the hatred between family and country, grievances between teachers and students, and personal growth unfolded, Lin Bufan transformed from an ignorant boy into a true strong man responsible for saving the world. The three-volume story has a tight rhythm, and events progress layer by layer. In the end, the three realms are unified, the protagonists each get their own place, and it ends successfully with laughter and emotion.
