"What is this fundamental rule?" An Guan asked.
"The relationship between the elements," Amon answered. "I see a similar theme throughout the recorded pocket worlds discovered from roughly the same era. Added with the accounts from previous participants, I'm fairly certain I'm not wrong."
"Each trial stage indeed heavily showcases one type of the elements," Huang San said.
"How can we utilize this information?" An Guan asked.
"As Huang San mentioned, each sub-space will focus on a single element," Amon said. "The key to solving that particular sub-space is using the opposite element that trumps the element inside that sub-space."
"In that case, shouldn't we look for participants with different elemental affinity?" Wu Di said.
"It's too late for that. I can't change my companions anymore," Huang San stated.
