บท 1304: Seal flag inside the sand sinkhole

Cha Qizhao continued explaining, "The demon realm entrance is the furthest from here. Even with an extreme grade flying cultivation artifact, it would take half a year to reach it. No one has said to be able to return from the demon realm entrance. The blue sand ditch is at the north of the Sand River. It's an area of about a few hundred square kilometers. The sand there is all blue, even the sky there is blue, no one can go near there. The temperature there is like a furnace. Those cultivators who near there are all burned to death, even truth realisation states can't get near there."

Ye Mo was shook, the blue sand place was this terrifying! Even truth realisation state cultivators couldn't go in.

Cha Qizhao continued, "The sand near there has been baked to stone, it's very tough and it's said that the stones can be used as magic artifacts, with its toughness on the same level with cultivation artifacts."
