In the "filthy soil" at the bottom of the Nine Heavens, acid rain corrodes the earth, and despair is the only color. Fifteen-year-old miner Chen Li, carrying his terminally ill sister Chen Xiaoyu on his back, struggled to survive like an ant. Looking up, only the cold light of the monk's sword streaked across the sky, which was the "top" that they could not touch.
When the devastating "Calamity of Sinking Abyss" tore apart the filthy earth, and the torrent of evil energy of destruction swallowed everything, Chen Li, in order to protect his sister, introduced evil into his body in a desperate situation, and unexpectedly awakened the taboo power hidden in his body - **Taotie Martial Vein**! This vein can swallow all things and turn evil into power, but it also brings backlash that tears apart the soul and a cold and hungry will. The mentor "Old Cripple" protected him with his life, and his last words were: "Take Xiaoyu... To the sky... To find the truth!"
Carrying his loved ones on his back and the devouring power of the brand, Chen Li's cognition completely collapsed. They are not dust, but abandoned children trapped in the nine-layered heavenly domain. From a miner in dirty soil to a god of martial arts who crushed the sky, he entered the Tao with martial arts and conquered the heavens with his fists. Devouring the essence and blood of ferocious beasts, smelting the earth and stars, fighting bloody battles in the wilderness, fighting in hundreds of rivers, breaking through molten fire to forge bones, and asking for the way to float... All the way bloody, against the conspiracy of the mysterious organization "Nine Nether Alliance", tearing apart the hypocritical mask of the high-level heaven.
However, when he finally stood in front of the rift in the heavens and faced the source of the eternal catastrophe, a truth that overturned everything suddenly came to him: the power of Taotie that he was proud of/hated, and his sister's dying but miraculous bloodline, were actually fatefully entangled with the scar that tore the universe apart!
