Chapitre 259: LABORATORY ROOM.

After entering the tunnel passage completely, through their night vision goggles, Clark and Dickson moved forward at a fairly swift pace.

They crawled forward at a steady speed with their body laid horizontally and exposed vulnerably, they could only pray that no enemy would suddenly spring up to them at such bad timing.

Though the hollow tunnel passage was dark, Clark who was at the front could detect faint blue flashes that were probably from electrical malfunctions lighting up occasionally on the metal walls.

He could not pinpoint what was causing it at this moment, he could only rein in his curiosity and focus on moving forward while paying attention to the flow of time to know how long this tunnel was.

After crawling forward for about 5 minutes, Clark noticed a hole leading upwards on the tunnel wall that was just before him.
