"Lin Fei, since you could escape the pit of fire, I suppose you can also get through this Four-Ring Underground Palace. I won't play with you anymore; I need to return to the pleasure boat at the Sea of Death and accompany my beauties, hahaha..."
At this moment, the sinister voice of Old Prince echoed inside the Underground Palace, accompanied by a smug laugh.
Yet, his figure was nowhere to be seen, and the origin of the voice could not be determined.
After the voice, silence fell; obviously, the Old Prince had already left.
Lin Fei's gaze turned to the beast-head copper rings on the four walls; he knew he had to take a risk.
Only one door ring led to escape; the remaining three copper rings would trigger deadly traps.
Lin Fei first focused his gaze on the beast-head copper ring in the middle of the eastern wall.
He would start with this door ring.
Swish.
Lin Fei's figure darted forward, landing in front of the eastern wall's copper ring.
