The power of the netherworld radiated to Hell, and thus Satan, the Lord of Demons, was born.
His ambition was too great as he wanted to emulate the Underworld Palace's establishment of the Six Paths of Reincarnation and a complete system in the Western Hell. So, he created the "Death Gods" specifically to hook the souls of the living on earth, and with the help of the netherworld's power, he forged the "Rebirth Hall" to achieve reincarnation.
In the days when the netherworld fought the Underworld Palace, Satan even wanted to take the opportunity to invade the palace.
However, he overestimated himself and underestimated the strength of the Underworld Palace.
Satan led the Hell army to invade the Underworld Palace, but before he could set foot in Fengdu City, he was driven back by the one-man force of Lord Cui. Since then, Satan had become calm, closed off for hundreds of years and never showed his face again, not daring to bring up his ambition to invade the Underworld Palace.
