There was no way Vritra can defeat it even within a few years, even after going all out with every technique.
Not that he planned to do that anyway, his goal was fundamentally different from simple combat… slowly devour it, and completely make this his own power through consumption!
His shattered body quickly reformed with effort as he plunged into the illusory body desperately, using book of dimension, forbidden, nether eye and Suck! Suck! Suck! at the same time.
Usage of book of dimension and forbidden allowed him to pass through the first defence of the illusory body and nether eye was used to move in the correct direction toward the core.
Then with Suck! Suck! Suck! he devoured the illusory body itself greedily, eating his way towards the centre, after all it's still a form of energy susceptible to absorption.
But that wasn't the main goal, within a moment, he reached the flesh and…
MUNCH
Directly bit down at the flesh of the titan with all his might!
