222. Unlock the Giant Rat Manual! Mechanical genius girl shows her love!
An unexpected earthquake caught everyone in the gymnasium off guard.
Fortunately, the earthquake didn't last long, ending in just a few seconds.
What followed was the screen above the Central Martial Arena displaying scenes from downtown.
It was the perspective of a drone.
Lin Zichen looked at the screen and saw the Scarlet Giant Tree in the image, beneath which the land had collapsed into dozens of bottomless caves.
The mouths of the caves were densely packed and seemed like black holes in space that could swallow everything.
A group of well-equipped mechanically modified humans didn't dare to approach recklessly for inspection.
They only dared to release detection robots from a distance, controlling them to enter the caves to explore the depths.
The detection robots had just approached the edge of the caves.
The next second!
