This story takes "the martial world under the guise of modern cities" as the core, shaping the growth arc of ordinary college student Lin Yu from "passive awakening" to "active guarding". By adding family secrets, camp games, and ability awakening branches, each volume has a strong ups and downs rhythm of "crisis outbreak - desperate situation is broken - clues are upgraded". At the same time, the character's personality is deepened - Lin Yu's "hot-blooded forbearance", Su Yao's "cold on the outside and hot on the inside", and the "paranoid and ruthless" of the leader of the Shadow Society, deeply binding the character's behavior and personality, creating a suspenseful legend of martial arts.
