The silver-haired god Ling Qingxuan is the incarnation of the "Nirvana" of heaven, and is ordered to kill Yun Zhi, the reincarnation of "Qing Po". However, when he witnessed a mortal girl willing to die to save a child, the Taoist heart that had been frozen for thousands of years cracked open. He went against his destiny and accepted her as his disciple, personally guarding the biggest "loophole" in the way of heaven.
Since then, the ultimate tug-of-war has been going on every day on Snow Sword Peak. He taught her how to practice swordsmanship, but his sword energy instinctively protected her; she gave him wild flowers, but he threw them away with a cold face, but turned around and cast a spell to last forever. The battle between reason and emotion raged in his soul until her identity was exposed. In order to save her life, he was forced to conclude a "same life contract" and was completely overwhelmed by her turbulent and pure emotions for the first time.
In order to protect her, he personally threw her into the Abyss of Demons and staged a "cleaning up the family" that everyone in the world believed. A hundred years later, she returned from the sea of blood and became the red-clothed devil, facing him with swords on the battlefield. They are mortal enemies in the eyes of the world, but they are the only allies in the dark night. While falling in love and killing each other, they join hands to fight against the divine punishment.
When he burned his soul for her, she realized the truth in the Palace of Reincarnation - she was "love", he was "reason", and they were one. She did not hesitate to sacrifice herself in exchange for the rebirth of Chaos. In the end, they used themselves as the basis to reshape the way of heaven, and established a new world where "emotion" is not a calamity, but the foundation of the way.
