Alex recognized the young man. He was Yao Bujiang, the one with the reflection dao that he had fought in the battle hall a few years ago.
He looked at the other 3 people as well, and each one of them was very strong. To have reached this high, they needed to have a cultivation base that was strong enough to survive through all the trials and challenges.
"Do you know what the challenge is by chance?" Alex asked.
"Don't be in a hurry," the young man said. "You will find out soon enough."
Another man entered a few minutes later, and a woman came in nearly half an hour after that. Finally, another 15 minutes later the final person entered the room, and the gate closed.
At the same time, the room started speaking.
"This is the Alchemy challenge," the voice said, making many of the competitors frown immediately. Alchemy was the last thing they wanted to have to go through as they weren't very familiar with it.
