Flame Dragon Uri

William waited over an hour for the Molten Dragonstone to cool to an appropriate temperature. The process took quite a bit longer than expected due to the unbearable heat of the second floor.

He didn't have a great way to check the temperature of the Dragonstone, so he asked the System.

-650 degrees Celsius.

Geez, how long will the Space Ring last?

-Around five minutes.

It was enough for William. He picked up and stored the Dragonstone, then moved as quickly as possible without revealing his position to the back of the room where a staircase was forming. 

As he climbed the staircase, a group of Cultivators came in through the entrance, their presence hidden quite well. Among them was the runner that William forced to scout the second floor. They peeked into the floor similar to how William did, just in time to see him sneaking up the staircase.
