The cold water of the Chu River split the world. The Wolf Clan on the north bank used the ice soul as its soul, and the Yuntai Sect on the south bank used the fire soul as its bones. The two forces of ice and fire strangled the river for hundreds of years, and the blood spray stained the plum branches of the Eighteen Peaks red. Ten years ago, during a bloodbath, Su Xin, the orphan of the Yuntai Sect, fell into Hanjiang holding half of a scabbard with the word "symbiosis" engraved on it. From then on, the mark of ice and fire was imprinted on his palm - it was the secret that his fathers had hidden with their lives: the sword soul of Hanjiang Jiuque was originally designed to allow ice and fire to coexist in the same world.
With half of the scabbard and the hatred of annihilating the family, Su Xin searched for the scattered sword spirit among the eighteen peaks of the Chu River, but met Jiang Xue, the saint of the wolf tribe, under Leiyin Cliff. There were icicle-like blue marks at the end of her eyes, and hanging from her waist was half a wolf head jade that fit perfectly with Su Xin's scabbard - it turned out that the saintly daughter and son of the wolf tribe and the Yuntai Sect had been chosen to be the carrier of the "Symbiosis Sword Spirit" since birth. The two people who were supposed to be mortal enemies saw the same scene when the swords resonated: the ancestors of the two clans had made a blood alliance in the Hanjiang Tower, using the sword as a guide, trying to make the two powers of ice and fire merge in the Chujiang River.
They broke through the thousand-year-old ice of the Shui Po Pond and caught the "Wind Sword Soul" blown away by the strong wind on the top of Leiyin Cliff; when the Fire Sword Soul fell in the wolf clan's forbidden area, Jiang Xue used the blood of the Saint to protect Su Xin from the bite of the ice wolf; when the Heart Soul Sword Soul lit up on the roof of the Hanjiang Tower, the afterimages of the ancestors of the two clans appeared on the sword—— The so-called grudges are just a trap set up a hundred years ago to prevent the imbalance of ice and fire. The real mission is to return the sword soul to its place and restart the symbiosis of Hanjiang Earthline.
