Eternal Night Plane.
At that moment, a massive vortex appeared in the sky.
If someone weak stared directly at it, they would see an eye within it constantly watching them.
Of course, it was not some celestial phenomenon.
Or rather, Eternal Night was not governed by heaven and earth.
The Plane Spirit here was entirely under Xiao Tianyang's control.

"Chaugnar Fagern's subordinate planes are limited by the size of their own territories."
"Therefore, their strongest forces are only somewhat stronger than the Sea of Ten Thousand Evils."
"As long as no outsiders intervene, completely clearing them will not be difficult."
"After all, the greatest obstacle was merely their coordinates."
"Now that we have the coordinates and the entire army is ready to march, those planes are naturally ours for the taking."
