Krune's group and the other cultivators and demon beasts kept moving forward after the vines room event. In the end, the number of passages that they had to chose kept increasing. Fortunately, Rarol's instinct wasn't just for show.
By now, the paths already surpassed more than 10 choices. But Krune and the others also noticed one thing. Behind them, there where other tunnels that connected to the paths rooms. It seemed like those who selected paths without any reward or traps would end over in the same place at some point.
Another thing that they noticed is that it was not possible to go back. Even though the passages were there, once you entered the room with the paths to chose, something like a formation would stop you from going back in any of the passages.
