At this moment, Qin Niu felt a scorching heat wave rushing toward him, blowing out from deeper within the cave.
He instinctively looked toward the deeper parts of the cave.
Because he had entered more than 200 meters into the cave, his current position was very dark.
In fact, just after entering about 20 meters into the cave, the light had already become very dim.
He noticed that there was a faint red light shimmering ahead.
It was like the glow brought by flames.
But there was a difference between this and the light emitted by fire. Flames usually flicker and leap, but the red light ahead was quite stable.
At this moment, standing in the deep and dark cave and seeing the red light before him, most people would have been scared off running for their lives.
In these deep mountains, and particularly within a secret cave, it was easy for demons and ghosts to lurk.
