Dr. Querzaros and Director Romon looked up in surprise. The shattered metal door fell like rain, but the two of them could not even be bothered to blink. For a moment, they seemed to have completely lost the ability to think.
This metal door was the last door that connected this base to the outside world. It was also the last defense when the base faced the outside world. The material used was an extremely strong alloy made by the most advanced technology of the alliance. It was said that it could even endure the full-strength strike of a Star-Grade Martial Artist without being damaged.
However, now, it was pressed down by Chu Nan's palm and actually shattered into small fragments that filled the sky!
Could it be that Chu Nan's strength had already surpassed that of a Star-Grade Martial Artist?
No, that was naturally impossible.
