Wallace has no idea why the Empire wanted to meet him. However, he's not foolish enough to follow them obediently and get himself captured inside the Imperial Flagship.
He trusts his abilities but there's still a limit on what he can do by himself.
Perhaps, if he's together with the Celestial, he wouldn't hesitate to agree with their request. This is at least what he thought after hearing it the first time.
Bam!
The Terub's aura collided with his Mana Shell and it created a disturbance in the surroundings.
'Tsk… So strong. Just what kind of power is this?!' Wallace grumbled in frustration.
Just the aura of the alien can already put pressure on any individual and if you're probably any weaker, you wouldn't be able to survive just by getting near him.
Nevertheless, Wallace managed to endure the Terub's incredible presence by circulating his Astral Energy.
