In order to save his best friend Chi Ling, whose soul was locked by heaven, Cang Wu broke into the ancient forbidden land of Blood Sacrifice Cangqiong alone, exchanged his life for his life, and forcibly tore the chain of seals. The moment Chi Ling's soul awakened, the heaven and earth changed suddenly, the divine blood flowed backwards, and the nine-layered sky opened with a trace of blood. The brothers who were side by side in the past, one carried the body of curse, and the other carried the soul of destruction. They are no longer sacrifices to fate, but god-killing blades. When the gods looked down at the world, their cangwu swords were stained with divine blood, and their red feathers cut through the heavenly rules. In this life, they did not seek to become immortals, but only wanted the sky to bow their heads for them.
