Ye Tianling, a young man from the mountains, saved a seriously injured old man due to a moment of kindness, and his fate changed. A mysterious sword seal and a incomplete "Nine Heavens Sword Code" opened the door to sword cultivation for him. Rising from humble beginnings, he first showed his talents in the sect competition, but was also involved in a huge whirlpool of conspiracy. In pursuit of the ultimate in swordsmanship, he moved forward with his sword, traveling throughout the mortal world, the world of cultivation, and even the ruins of the broken fairy world. In secret realm fights, he challenges the geniuses with his sword; in ancient tomb horrors, he inherits the ancients; in realm battles, he suppresses all races with his sword. Along the way there were thorns, singing songs all the way, his cultivation from condensing energy to the peak, countless corpses lying under the sword, and he also made close friends and beauties. When he finally broke through all the shackles with his invincible appearance and stood on the top of the Nine Heavens Tower, full of longing to touch the legendary realm of ascension, the cold truth choked his throat - in front of him was not a free fairyland, but a boundless cage with more cruel laws and vaster boundaries. Looking back, on the way back, eight tombs of sword masters stood silently, as if telling the fate of failure. Will he become the ninth fallen sword master, or will he use the sword in his hand to carve out a new future for the world?
