章 353: Chapter 351-a big firework

The weather was getting colder, the yellow leaves were falling, the bare trees were shivering in the wind, and there were few pedestrians on the empty streets.

Tang Zhen strolled along the street like a leisurely traveler.

The foreign buildings on both sides of the street didn't attract his attention. In his mind, he had been planning how to sneak into the target location.

The place they were going to sneak into this time around had a very high security level. However, it was unable to stop Tang Zhen from entering.

He first figured out the specific terrain of the target location and the surrounding buildings before he hacked into the network system again.

After figuring out the specific defense arrangement, Tang Zhen began to act.

Tang Zhen, who had activated the [ quantum invisibility light curtain ], quietly entered the target location. After that, he avoided the patrolling guards and sneaked into the underground facility.
