Cheng Yuan was originally a senior high school student suffering from depression. He committed suicide and traveled into a small world, where he passed through Ji Qingci's body (prenatal transmigration). After a long period of transition, his destined person appeared and redeemed Cheng Yuan, but they were only supporting roles.
Purpose: To explore the propositions of "self-acceptance" and "meaning of life" through the struggle and redemption of a depressed teenager in the world of immortality. When the protagonist thought he was just a stand-in for the NPC in the book, he spent a long period of loneliness fighting his inner demons in his own way, and finally understood: the real way is not to change one's fate against nature, but to reconcile with one's own pain; the real salvation is not to rely on the light of others, but to light a lamp for oneself in the darkness.
