Modern office worker Yang Guo stays up late rewatching The Return of the Condor Heroes. His vision goes black, and he finds himself transmigrated into the teenage Yang Guo, fleeing in a sorry state beneath Mount Zhongnan! Before he can even process the bizarre turn of events, a cool figure as clear as the moon appears before his eyes: the real Xiaolongnü!
But this Yang Guo is not the same as the original. He lacks the exceptional talent of the novel's hero, possessing only a modern man's memories and a heart tempered amid steel and concrete that treasures this miraculous chance to transmigrate. The ancient tomb's icy jade bed, their days and nights together, his clumsy breathing exercises and awkward sword moves, each accidental touch of their fingertips, each faint ripple in her cool gaze, all quietly stir his heart. He is no longer the rebellious, defiant "Guo'er," but a visitor from another world whose sole resolve is to protect her.
One crisis follows another! The poisonous palms and schemes of Li Mochou, the Crimson Serpent Fairy, hang over him like a sword. A desperate counterattack unexpectedly awakens the mysterious power of the ancient tomb's treasured jade bee honey, causing the frenzied swarm to mutate! These spiritual bees, carrying a mysterious ancient bloodline, not only spare their master but come to regard him as the heart of their swarm, forming a strange bond beyond master and servant. The power of the swarm becomes his first trump card in this perilous martial world.
The cold pool behind the mountain is unfathomably deep. While fetching water, his senses, strengthened by the jade bee honey, reveal a sword-shaped shadow at the bottom of the pool: an ancient sword, silent for a thousand years, its cold gleam concealed! This treasure, seemingly tied to Wang Chongyang and Lin Chaoying, is both an opportunity and a test, a sign of a grander world and even greater challenges.
Determined to gain the strength to protect those he holds dear, Yang Guo resolutely sets out on a thorny path!
