The little human King controlled the human King corporeal body. After reaching the true immortal realm, the power he could unleash was too strong. He could be invincible with just his corporeal body.
This was also something he could do because he and the human King Xuanyuan were father and son. If it were anyone else, they would never be able to enter the body of a peak Celestial King.
The little human King was incomparably powerful. He stepped forward and turned his fist into a palm. His palm was like a sword, and as it slashed down, a shocking sword light exploded.
The little human King's body was the body of the human King Xuanyuan. He didn't even need to use an immortal weapon. His body alone was already comparable to Immortal Weapons, and even harder than ordinary Immortal Weapons.
