The Flat Louse Amber Worm was madly devouring Russell's blood.
But it wasn't doing so to consume Russell's blood, instead, it was transforming his blood into another kind of energy which in turn was being fed back into Russell's body.
This energy was the Second Turn Primordial Breath covered by a layer of Dragon Breath, the power that Russell had lost previously when he was defeated by the Snow Giant Da.
Through its ability to convert Qi and blood, the Flat Louse Amber Worm continuously transformed Russell's blood back into the power he had lost. And this power supported Russell's cognitive functions and helped him gradually restore his spiritual power despite his body being cracked.
It was precisely with the recovery of his spiritual power that he could feel his left hand and the burning mark in its palm.
Finally.
He felt the Guardian Lizard Amber Worm constantly emitting its mysterious power to repair Russell's damaged body.
