The demonic disciple who was looking at Fuangu with mockery was at the early Foundation Realm as well but had formed his 3rd Divine Platform, making Fuangu one stage weaker than him. He had been toying with him so far but seeing Fuangu’s actions he couldn’t help his eyes from going wide.
“Are you insane burning your life essence like this?!”
Fuangu burning his life essence gave him strength equal to his own. He was already weakened so with this Fuangu went from someone he could kill with a bit of effort to being able to threaten his life.
Even though it was temporary Fuangu looked completely out of his mind.
He took a step back, but Fuangu didn’t hear him and with eyes completely red he reached him before slashing down with his sword as hard as he could.
The demonic disciple awkwardly blocked his attack but was pushed back.
