The Demon king had proceeded to wrap the chains around his right hand while leaving the other half as a lasso in the left!
Mostly on the Demon King's right hand, more of the chains were wrapped around his knuckles while causing sparks from the gauntlet while drawing back for a punch due to the tight clenched fist.
Muzan had starts to get on all four of his limbs while charging at the Demon King, a beam is formed again in Muzan three heads as the distance continues to close!
The Demon king quickly appears in front of the Cerberus Muzan while giving a three uppercut punches simultaneously to each head along with a frontal punch to the middle head a second time, causing Muzan to be sent flying to the back of the main entrance to the Demon Kingdom, As for the Demon King who had a smirk was plastered upon his face due to the early fact of having to suffer under chaos energy wrapped in demonic energy!
Due to tanking the Demonic chaos energy attack, it caused some internal damage from the chaos wrapping around it.
Due to being the Demon King, it had felt as someone had hit him with a blunt object in the stomach due to the Demonic energy immunity as the King he somewhat has!
The Demon King had to cough out blood in his palm, so his full strength was needed to be used as a chance for a break to recompose his stance for a brawl due to the force used up by the Demon King half fully strengthened attack it could be said some Damage was done back to the Cerberus form of Muzan.
This time, the realization had settled in the Black heart of the Demon King.
If he wanted a perfect vessel for himself, then the only option is that he would have to lose an arm or a leg in this battle for a successful outcome.
Eventually, in the plans of the Demon King to take down the goddess clan, loss is to be expected from an entity born from Chaos as well.
