The young man with gray hair's reminder did not make Zhou Chen retreat. He quickly entered the door and observed the situation inside.
It looked like a long room. There was a wooden box on the ground more than twenty meters away. There was nothing in the middle. The only thing that was suspicious was the dense black holes on the walls on both sides of the room.
"That box looks like it is free for anyone to take. This is definitely weird. The flames should be coming from these holes."
Out of caution and the young man's reminder, Zhou Chen slowly walked inside.
At the beginning, nothing happened, but when he walked a little further than two to three meters, the dense holes on the walls on both sides spewed out hot flames, instantly filling the room.
Zhou Chen immediately retreated to prevent his clothes from burning.
After he retreated, the flames from the holes on the walls quickly stopped.
"Is this a test of speed…"
