In the Lingxi Sect of the Cangwu Mountains, a heavy snowfall sent Yun Nian, an orphan with the spiritual roots of chaos, to the throne of Shen Qinghan, the No. 1 Man in the world. He was ignorant and naive, and became the favorite of the entire sect, and was carefully guarded by Shen Qinghan, the cold immortal lord. During the trial in the secret realm, the power of chaos unexpectedly awakened, good and evil coveted him, rumors spread everywhere, and the name of "disaster" made the young man breathless. In order to protect him, Shen Qinghan broke the precepts and left seclusion, destroyed his cultivation, broke with the sect, and fled with him. The immortal who has been lonely for thousands of years opens his heart to a pure young man; the little junior brother who once needed protection grows rapidly in love. When the traitor Mo Chen triggered the world-destroying formation and the three realms were at stake, Yun Nian was no longer a hothouse flower. He controlled the power of chaos with love as a contract and broke the formation side by side with Shen Qinghan. Breaking the taboo between master and disciple, making an alliance with Tao and swearing by love, this is a story of pure love that has been passed down by immortals for thousands of years. It is also a legend of immortality about protection, growth and redemption.
