The map that the Scattered Cultivators House distributed pointed them toward a place called Yao Ru City. It was said that the Yao Ru City was the only immortal city that contained a transportation array that led toward the Corroding Vacant Valley. Given Lonemoon's and Yi Qing's speed, they arrived at that immortal city in a matter of days. They went straight through the transportation array, into Corroding Vacant Valley.
The moment they emerged from the array, they felt a chilling aura all around them. There was a huge valley in front of their eyes. It was almost as if the entire earth was cut into two by that one valley. There was nothing but desert on the side they were on. The other side looked like a bottomless pitch-black hole. A black aura as dark as ink was being emitted from inside the valley.
