Yu Weimin reached the entrance of the forbidden realm within a few minutes. It wasn't that far from the cave he had transferred to back then. So he just boarded his sword and started his flight in that direction.
The system just gave him the direction, and he would have to identify the forbidden realm door by himself. Actually, there was a reason why it was forbidden. There were many hidden dangers that could even lock you up for eternity, and you wouldn't even realize it.
Even more irritating was the fact that the door would always be hidden. If someone got help from a senior or was in the latter group themselves, they could perhaps enter the realm.
But Yu Weimin was none of those. He only had memories of Liu Yang.
