"Wow, Da Guan can climb the net as fast as a monkey everyone. He has reached the fourth sub-fire-level in the blink of an eye," the host said, narrating Da Guan's progress.
The fourth sub-level was just a pathway that twisted and turned like a labyrinth, only the walls along the pathway were made of fire that was ejected up from the floor. At the end of the sub-level, there was an area to rest and drink 1 glass of water. The show would stop the time and let the competitors drink water for 2 minutes. In this sub-level, Da Guan used the oxygen tank provided by the show.
After Da Guan finished drinking his water, the time started up again. He was at the fifth sub-level. It was the level where the competitors had to find the reward balls from a hot sandpit. There was fire around the pit. Da Guan searched quickly. He found 2 balls shortly after that. Not wasting his time, he quickly chose one of them and went to the next level.
