Hao Ren knew precisely what that road sign meant.
It led to the lost divine realm of the goddess of creation, a forsaken place without divine blessing and protection or thriving life. No one knew what happened to the place, but the fact that the great explosion caused the divine domain to plunge into the Umbral Realm 10,000 years ago, was enough reason for Hao Ren to be mentally prepared for any eventualities.
There was a high possibility it was going to be a broken and crazy world. Additionally, the power of the Mad Lord and the remnants of the deicide could likely still be lingering around there. If the goddess of creation could survive, there was no reason that the opposing forces could not.
The Petrachelys could cross the boundaries of space and time to enter the lost Umbral Realm using that signpost. But anyone in his right mind would know that it was a bad idea to go there without preparation.
