On the day Ling Jin was expelled from the sect, his blood was stained for a long time, but he unexpectedly awakened the ancient demon king's legacy, and the demonic energy sealed in his body tore through the shackles of heaven. In the past, his fellow disciples regarded him as the source of trouble. Only Yuchi Xiao, the old master of the Demon Realm who had been imprisoned for thousands of years, broke out and recognized him as his successor with a blood contract. One is an abandoned son spurned by heaven, and the other is the remnant soul of the demon king who has been sealed for thousands of years. Their fate has tied them to the same bloody path. When the righteous way wants to kill the demon king's legacy, Yuchi Xiao uses his soul as a sword and Ling Jin uses his body as a furnace to change his fate against the will of heaven and burn all the false ways.
