As for the fact that Yan Shuangshuang was here to save people, the man never considered it. Although the man was a member of the Cannibal Clan, it didn't mean he was unaware that other tribes, while not consuming human flesh, weren't particularly empathetic either.
The man had seen many Great Tribes. He had never seen a tribe that would rescue people from their Cannibal Tribe's hands. Sometimes, when the Cannibal Tribe was chasing others, people from Great Tribes would pretend they hadn't seen anything, completely afraid to offend them.
Without suspicion, the man raised five fingers at Yan Shuangshuang, flipping them twice—once meaning five and twice meaning ten. After stating his price, the man said, "I only want this number of Stone Axes, nothing else, and they must be well-polished, made of good stones."
