In the Tianxuan Continent, there are thousands of races, and the strong are respected. Lu An, the young master of the Lu family in Qingxuan City, was born with the "Nine Sun Holy Physique". He was originally a unique genius, but he was betrayed by his beloved Lin Xueyao and his brother Chen He, who destroyed his cultivation and took away his foundation by eating souls. In the tragedy of the entire Lu family being wiped out, Lu An fell off a cliff. He thought he was dead, but he accidentally awakened the ancient divine sword Tianyan in his body. In this divine sword, the soul of the eternal number one weapon refiner, Alchemy God, and Formation Emperor Xuan Tianji is sealed. Lu An used his own blood as a guide to fuse with the divine sword and obtain the ancient body-refining technique. Three years later, a masked boy named "Huang" appeared in the assessment of the top school "Wandao Academy" with an invincible appearance that swept his peers. His return was just to pay for his blood debt and break through the sky!
