Kassadin, Malzahar, and Vel'Koz, who stood beside him, could not help but have their expressions change drastically at the sight.
Of course, with their deep-purple faces and pitch-black pupils, it was impossible to tell whether their expressions had changed at all.
Vel'Koz in particular was just a giant eyeball. Forget changing expressions—even whether he had a face at all was debatable.
However, they were not in the leisurely mood Xiao Tianyang had to dwell on such trivial matters.
As Void Creatures, the places they invaded most often were Low-level Planes like the Douluo Continent.
Even those with strength above level one hundred could not enter such places lightly.
Yet, with their ability to use Void Shuttle, they could ignore the rules and launch massacre after massacre, spreading chaos wherever they went.
But such great convenience naturally came with corresponding restrictions and weaknesses.
For example, once they were discovered by the Plane Spirit, they would have to endure Punishment Thunder capable of reducing them to ashes!
It was a tracking method they could not escape even by hiding in the void!
Furthermore, once a large-scale void invasion was detected, the Plane Spirit of that world could adopt emergency measures!
In other words, it meant "closing the borders"!
It was essentially equivalent to creatures outside being unable to enter, while creatures inside could not leave.
