Mo Lin, a swordsman who cultivates immortality in the Kunlun Snow Region, and Anlong, the red-haired demon king who rules all demons, were originally incompatible enemies. However, in repeated confrontations and side by side, they crossed racial barriers and developed a forbidden love. The tenderness of making tea in the bamboo hut and the tacit understanding of the bloody battle in purgatory have become a tacit bond between the two.
When the demons broke out of the seal and the three realms were overturned, Mo Lin stepped forward with a broken sword, and Anlong led the demon soldiers to crush the beacon smoke. Together with the white-haired monk Xiao Huanyan, the master of Qingming Sword Ayu, and the lonely swordsman Shen Yan, they built a barrier to protect the world with their flesh and blood.
Anlong lost his memory because of the sealing of the demonic energy, and his red eyes were filled with confusion. However, in the shadow of the sword, he instinctively protected Mo Lin behind him - the care that was engraved in the bone marrow never faded due to forgetfulness. The love between Ayu and Shen Yan grew in the flames of war, but they could not escape the separation between life and death. She held the blood-stained epee fragment tightly and followed him into the fissure of purgatory.
The final battle is filled with demonic energy. Mo Lin and An Taki, who had recovered their memories, looked at each other and smiled, using their bodies as torches, they hugged each other tightly at the moment when the devil's heart was shattered, letting the flames devour each other; Xiao Huanyan held the broken chain of Ziyou Sword and watched his former best friend turn into ashes, with only Bai Gu by his side. It is said that the living people suffer the most.
Five people went to death and two lived alone. Only Qiyue Valley, where all the peach blossoms have fallen, hides the most painful concern and the strongest loyalty in the three realms.
