Ye Wuchen, a handyman disciple of the "Tianjian Pavilion", the number one sword sect in the world, was born with a weak pulse and received cold looks. While cleaning the Sutra Pavilion, he accidentally fell into the forbidden "Sword Burial Abyss" and found a broken black unknown ancient sword among thousands of broken swords and dead bones.
The moment the ancient sword entered his body, a strange meridian diagram lit up inside his body - it was the ancient ancient magic technique "Ni Cang Jue". This technique reverses the meridians, swallows the divine weapons, and nourishes the body. From then on, the dead veins became divine veins, and the waste materials turned into monsters.
During the day, he was a bullied sweeper in the sect, but at night he transformed into a black-clad sword demon, devouring magic weapons and testing the world with his sword. Until the witch Su Qingcheng, who was despised by the righteous way, broke into his life, saw through his secrets, and brought a shocking prophecy about the broken sword: "The sky is dead, and the rebels must stand!"
