Capítulo 270: Magnetic Field Reversal

Luo Yuan lowered his body and went through the thick metal door. Underneath the door was a typical basement staircase, and on both sides of it there was light. It was as bright as daylight.

After crossing five levels about 20 meters deep, they entered a long, three-meter wide channel. Every twenty meters, there was a soldier on duty. It was a pretty tense atmosphere, and everyone could feel the pressure.

Luo Yuan knocked on the wall of the channel with his weapon's handle. Using his Sensory Perception, he discovered that the wall was more than a meter thick. That kind of thickness could withstand even a cannon bombardment.

Luo Yuan was relieved. Against such defense, even a green level mutated beast would need to put some effort to break in. He continued to walk for another minute, passing by three thick metal doors, each about 50 centimeters thick. The noise got gradually louder as the team reached the hall.
