Legend of Nine Heavens Sword Immortal

He was originally a warrior in the mortal world, with a three-foot green blade that could cut off the shackles of the world. By chance, I embarked on the path of cultivating immortality, only to discover that the so-called immortality is more cruel than the human world. From the mortal world to the Nine Heavens, from an ant to a swordsman, he has gone through thousands of calamities and entangled relationships, just to protect the human fireworks behind him. If the way of heaven is unfair, I will kill him with one sword; if the people are in trouble, I will take their own life to take their place. This is the story of Ye Yun, a mortal who used the sword in his hand to carve an eternal legend for the world.
