There was no light inside the tunnel, Wang Tao and Lightning led the way at the front, while He Jijun and Lan Yulian walked in the middle with ultraviolet flashlights, with Jiang Shixue and Blacky covering the rear. They proceeded in an orderly manner into the tunnel.
The tunnel was very long, exceeding Wang Tao's range of perception, so he couldn't "see" what was specifically on the other side.
After some time, the group finally made it through the passage.
Wang Tao discovered several dead Fourth Order Elite Night Demons near a stationary Night Demon Type II, which surprised him.
