The stone slab in the center of the altar opened, revealing a square entrance. Lin Tian ran up, seeing that inside the hole was a downward-sloping passage.
The walls of the passage emitted a faint earth-yellow light, barely illuminating the way downward. However, at the end of the passage, there was a turn, and the situation beyond was out of sight.
"Someone is clearly guiding us, we must go down." Lin Tian turned to face the four beauties below the altar and paused before continuing, "But, to be safe, someone must stay to guard the entrance. It may be our only way back; we cannot afford to lose it."
"I'll stay. If anything happens, I can inform you at the fastest speed," Mu Yun calmly said.
She knew Yin Yang Shuttling Technique, making her the best choice to guard the entrance. Lin Tian nodded, taking the lead into the passage and walking down the stone steps.
