There are rumors in the world that the infamous "Blood Clothes Alliance" is wreaking havoc in all directions, plundering people and poisoning the martial arts world. The only one who can compete with them is a pair of heroes who are both enemies and friends - Liu Qitang, who came from a noble family but betrayed his family and used a soft sword "Tang Ying" to traverse the world. She looks lazy and casual, but in fact she has treacherous swordsmanship and specializes in picking out the villain's weak spots to attack. Wherever she passes, Tanghua will be stained with blood and the villain will become frightened.
Xiao Jinshuang, a stern swordsman with a mysterious origin, holds a dark iron cold blade "Jinshuang". The sword comes out like snow and blood seals his throat. He walked alone, but due to a chase, he met Liu Qitang on a narrow road. The two fought against each other when they first met, but they couldn't decide the outcome, but were forced to join forces to fight against the Blood Clothes Alliance's encirclement and suppression.
From then on, one was as willful as the wind and the other was as cold as ice, from testing each other to tacit understanding. Along the way, they tracked down the blood-clothed alliance, uncovered tricks, and killed evildoers. Wherever they went, the villains were frightened by the news. However, as the truth approached, the two discovered that there was a deeper conspiracy hidden behind the Blood Clothes Alliance, and their fates had been entangled many years ago...
Where the tang flowers ashes, a frost blade cuts through the night. In this bloody world, are they each other's salvation or their ultimate doom?
Purpose: to break the conspiracy, kill evil spirits, and stir up injustice in the world; to illuminate the long night, wash the blue sky, and keep the mountains and rivers clear.
