The mine was pitch-black as ink. Although martial artists who had entered the True Essence Realm possessed a degree of night vision, in this completely dark mine, they still needed to carry torches.
Ye Zhen, Fast Sword Cao Bufan, and Iron Palm Gao Xiong had barely entered the mine on the right side for a few dozen breaths when shouts of battle erupted.
The shrill voice of the Red-clothed Venerable was particularly piercing to the ears, and faintly, the shocked cries of Xie Shao, who had entered the middle mine, could also be heard.
As they delved deeper, after a few hundred breaths, the other two mines had encountered two or three waves of Demon Beasts and even sounds of injuries were heard, but the mine where Ye Zhen and the others were had not encountered even a shadow of a Demon Beast.
"Strange, they are all fighting so fiercely, why is there no movement on our side?" Iron Palm Gao Xiong was puzzled.
"That's a good thing, isn't it? Or are you unhappy about it?"
