At this moment, on the other side of Earth.
Xu Xin and Xu Ying had been stealthily searching inside the World Tree for a long time.
Wearing cloaks of stealth, coupled with Xu Ying's ability to teleport at any moment, they hardly held back.
Both of them had virtually gained nothing just now.
The feeling this World Tree gave them was...
Too safe.
This safety wasn't for the two of them, but for the alien invaders living inside the World Tree.
The situation outside had become severe, their leader had activated four giant ships to leave, and the monsters had triggered countless alarms, putting all the alien invaders and various military facilities below on full alert.
Yet inside this World Tree, surprisingly...
So peaceful.
As if nothing had happened at all.
On their journey, the two encountered at least dozens of alien invaders.
These aliens were different from the ones Xu Xin had seen at the World Tree before, the ones running stalls.
