Hidden Sword disciple Ye Fan became the laughing stock of his peers because his natal sword "Qiu Shui" had not been sharpened for ten years. At this time, a strange phenomenon occurred in the "Ili River" in the northern border of the Western Region. The vegetation flourished and withered overnight, and the undercurrents of the rivers and lakes surged with it.
Ye Fan was ordered to investigate, and on the way he encountered a disciple of the mysterious organization "Wuxianlou". This sect's martial arts is weird and can imitate the moves of various sects in the world. When Ye Fan was struggling to fight, he was rescued by Yunyao, a girl whose life experience was a mystery. The two went deep into the Yili River together and discovered that Wuxianglou was using the strange "source stone" to try to activate the legendary ancient power that can reconstruct the origin of the world - the "origin of mountains and seas".
In an ancient ruins, Ye Fan and Yunyao accidentally found the first fragment of the origin of mountains and seas. At the moment of contact, the two connected in consciousness, glimpsed fragments of each other's memories, and learned of Yunyao's heavy mission as a descendant of the ancient "Guardian". However, the power fluctuation attracted the masters of Wuxiang Tower, and the fragments were taken away. Yunyao was seriously injured, and his identity as the guardian was also exposed.
At this point, Ye Fan knew that he and this unsharp "Autumn Water" sword had already been involved in a shocking chess game that far exceeded the grudges of the world. The real purpose of Wuxiang Louzhu is to reshape the Dragon Vein of the Tang Dynasty and create his ideal "new order" by extreme means.
Facing ancient forces that can overturn the world, unfathomable powerful enemies, and confusing friends, Ye Fan must understand the true meaning of "no form" and find his own way. He joined hands with Yunyao to gather the Righteous Alliance in the desert of northern Xinjiang, vowing to prevent this catastrophe sweeping the world.
This is the legend of the rusty sword's opening, the fate of the guardian's bloodline, and a choice about strength, faith and sacrifice. When the power of the mountains and seas is once again activated, the fate of the entire Tang Dynasty depends on their thoughts.
Intention: The real power lies not in imitating all things, but in protecting everything that you and I cherish.
