"Heh heh..." Xu Ying chuckled softly, "They never would have imagined that what this time's invaders want to do is much more troublesome than they thought."
They intend to destroy the entire scarlet crystal and drive these alien invaders off Earth.
They couldn't have imagined things would be this severe, otherwise, they wouldn't have only sent seven or eight alien invaders to patrol here.
"Now there are only three of them, I'll take you guys up directly."
As Xu Ying spoke, she brought Xu Xin and Zhao Xiaochuan to a place temporarily unnoticed by those seven alien invaders, then lightly stomped her foot.
The three of them fell into a violet-black vortex and disappeared from the spot.
Then, they reappeared directly at the core of the World Tree, beside that hole.
Although the hole on the core of the World Tree was a pathway to an underground space, there were no alien invaders guarding here.
