The stone ball kept rolling forward under Shen Ye's patting.
Finally, it rolled into a fork in the path and fell into the underground river along the slope, disappearing from view.
The group continued to run forward.
Xiao Mengyu spoke up:
"So far, it has tested our brains, Resonance, Strength, Comprehension, and Combat Ability; I guess next it will be spiritual power."

"Figuring out how to land on this Floating Island—right, how did you guys get down?" Xiao Mengyu asked.
"Made a parachute, and then I have relatively high Agility, so I carried Doggy and landed in the lake at the end of the stream," Zhang Xiaoyi said.
"I see," Shen Ye said, "but how will they test spiritual power?"
"I'm curious about that too," Xiao Mengyu said.
About seven or eight minutes later.
The group arrived in a spacious hall.
There was nothing inside except for three small doors at the end of the hall.
