Yun Che, the sole heir of the reclusive Xueyuan Sect, possesses the "Ice Soul Mysterious Art," inherited from the ancient Ice God, capable of freezing everything in existence, resurrecting life and death. Since childhood, he has cultivated in the perpetually frozen Xueyuan of the far north, possessing a solitary and aloof personality. However, inspired by his master's words, "Temper your heart in the mortal world," he is ordered to journey to the prosperous Tianyan Dynasty to serve as a "shadow attendant" to protect Xiao Yuli, the crown prince candidate.

Entering Yanjing City, a stark contrast to the frozen wasteland, Yun Che astounds the Jixia Academy with his stern silver hair and unfathomable strength. Like a walking iceberg, he crushes challengers with his absolute zero strength, reverses fate with his life-or-death needle, and deciphers conspiracies with his celestial esoteric techniques. In his quest to protect Xiao Yuli, he must not only navigate the struggle for the succession to the imperial court and the feuds between sects, but also uncover the ancient secrets of his own bloodline and the Xueyuan Sect. The Ice Soul Jade, his companion since childhood, leads him to discover a long-forgotten truth.

The cold iceberg is not without mercy. As he fought against the will of heaven to freeze time and space for Xiao Yuli, and extended the life of a beloved concubine in the harem with an icy needle, his reserved protective heart gradually melted. From academy prodigy to a pillar of empire, from a lone disciple in the Snowy Abyss to a legend who captivated the frozen world, Yun Che ascended the ladder of power amidst the strife and swordplay, deciding the fate of the world with the power of his icy soul. Ultimately, all the proud and beautiful women—whether they were the chief law enforcer of the academy, the saint of Medicine King Valley, or the mysterious master of music—will willingly gather by his side, together composing a legend of ice and fire, of scheming and deep affection.
