The venue of Myriad God Ridge's entry test had a stone gateway erected on the square. It had four columns and a stone door made of three slabs. Gateways such as these were typically erected in front of villages in the mortal world to honor top scholars or chaste and heroic women. The design was very rarely seen in a warrior's world.
On the surface, the stone gateway wasn't special in any way. It even seemed a little out of place, standing in the middle of the square. However, when Yi Yun saw the stone monument, his brows pricked up slightly. He could tell that behind the stone gateway was the path to a pocket world.
If he circled behind the stone gateway there would be nothing, but if he were to travel through the gateway's stone door, he could step into that pocket world.
However, there was a restriction set up in front of the stone door. If one did not understand the restriction's rules, it would be impossible to gain entry.
