"Hey, that actually makes a lot of sense." Fisherman nodded vigorously. "Otherwise, we wouldn't have come all this way without seeing a single person or corpse."
After dealing with Xin Jiushiwu, the three continued along the red lights and passed through two more blocks before a rock wall appeared in their sight.
The second underground level of the Nameless Island Research Institute was unlike the first, which consisted of an underground network of tunnels and caves. It was one enormous hollowed-out subterranean space. A rock wall thirty meters thick divided this vast underground space into two areas: the "living area" and the "work area."
Passing through the passage carved into the rock wall would lead them to the laboratory area.
At the end of the road, a metal airtight door nearly three meters in diameter was embedded in the rock wall. The door was thick and solid, its surface marked by rough casting patterns, with crisscrossed reinforcement ribs running across its face... Yet, to Fisherman's frustration, he circled the airtight door once and still could not find the valve to open it.
"How are we supposed to open this thing?" Fisherman scratched his head. "Or can it only be opened from the other side?"
"The opening and closing of the airtight door are controlled by mechanical structures embedded within the rock wall. Those mechanisms extend all the way to the controls inside the research institute's security center," Yano said. "And the security center is indeed on the other side of the wall."
"Then we can only force our way through?" Fisherman said.
"...If I remember correctly, this airtight door is two meters thick." Yano sighed. "And it's made of an extremely hard tungsten alloy, not ordinary steel alloy... Haven't you noticed that after all these years, it hasn't rusted at
