"Father did you also...." The rest wasn't needed to be said. Adam just nodded his head with a serious look.
"It seems this ruin is more like a labyrinth."
Around 10 or 20 minutes later, another group of adventurers appeared. It seems this party of adventurers also had managed to break the illusion. As for what happened to those who couldn't break the illusion...they died while being trapped in the world of illusion. Inside the illusion world, their mana was sucked without them even knowing about it.
Soon an hour passed. In that hour, a few other parties of adventurers and a few rogue cultivators all joined them. Everyone quietly waited inside the room waiting for something to happen. Everyone knew in their heart that this was just the beginning. The real challenge is yet to come. Who's who manages to pass all the challenges will be able to gain rewards.
