The moment the cultivators entered the smoke barrier, they found themselves alone. Their enhanced sight could only give them a view of a few meters, and the lack of natural light that was supposed to come from their backs, showed that they had been teleported somewhere else.
After the murderous sense disappeared, a path made of white colored smoke formed in front of them. This path was only a few meters long, and at the end of it, was a white colored campfire, and a doorframe. Carved on the doorframe, was the phrase "Know to respect your limits, unless you wish to excel."
Most participants committed this phrase to memory, and began to walk towards the door while ignoring everything else. When they approached the white flames, however, they felt an immensely powerful, yet benevolent power crawl in their direction.
