[Two male protagonists] + [White and black] + [Past and present life]
Young Ni Lingzhi accidentally entered the sacred mountain and became a disciple of Tianyan Xianzun, for whom he secretly admired him. After his thoughts were exposed, there was a rift between master and apprentice, and he traveled down the mountain alone. During the war between humans and demons, Ni Lingzhi begged his master to come down the mountain to help but failed. At the ten-year banquet, their weapons turned against each other, and he abandoned his cultivation and rebelled against his master.
In the following hundreds of years, Ni Ling knocked on the seal of the sacred mountain every year. He died of serious injuries and planned to seek rebirth. After being reincarnated and worshiping the Tianyan Sect, he met the snow demon Yunli by chance in the secret place of the Bai family, and fell in love with her. Layers of mist were lifted, and Ni Jin finally knew that Yunli was the result of the splitting of Shen Gong Yan's own soul.
The two have been together for hundreds of years on the sacred mountain. Yunli's life span dissipated, and his soul returned to Tianyan Immortal Lord's body. The cycle of fate goes back and forth, a sacred mountain will always be guarded, and a forbidden love that spans the ages will fall into the snow and ice.
