Tra slowly pushed open the damaged stone door with the mercenaries, but he did not enter immediately. Instead, he tossed several Glow Sticks inside and peered in, finding nothing.
Originally, everyone had thought that once this passage was opened, swarms of rats would come rushing out. But in reality, not a single rat emerged.
The passage was still straight, constructed entirely of bluestone. The distance ahead was pitch-black, like a huge dark mouth waiting for people to step forward and offer themselves to death.

To his surprise, he really did find a Counterweight Stone here. Its structure was identical to those in the other three passages.
"Ms. Tina, there is also a Counterweight Stone inside, just like the other three Stone Doors," Tra said to Tina.
Tina nodded, then stepped forward to inspect it herself. After confirming it, she had the mercenaries carry over a chunk of rubble more than a meter tall that had just been blasted apart and place it inside the door panel.
