Ye Chen passed through a dark tunnel and entered the Sunken Jade Tower. Looking ahead, a vast underground world appeared. The ground was covered with a towering forest full of jagged rocks where numerous black underground plants grew. The dusky sky concealed the top of the rocks but there would occasionally be colorful halations flowing.
This underground world was densely bound by restrictions and one could only pass through the narrow passageways between the restrictions.
From time to time, strange shrieking screams could be heard from a distance. Nearby was an open ground covered with crushed stones, and occasionally, a number of humans and beasts bones could be seen. No one knew who killed them but there were hundreds of such bones left behind. They were all dull and gray as if the corpses had been drained of blood.
