Sages-to-be were a considerable threat in Untainted Land, not only to the Wu and Demon Tribes but also to the future Human Tribe. For this Cultivation Tribulation of the Wu and Demon Tribes, having at least one master of the Sage-to-be level was better than nothing. The moment this Tribulation was completed, even the Daluo Golden Immortals would be scarce. If they survived, they would most probably choose to live like a recluse.
Though the setup of this situation was overt for Minghe, he had no choice, but to get involved. If he could get the Hong Meng Immortal Qi and gained the Enlightenment from it, it would greatly benefit his cultivation of the Divine Law. Minghe had not thought who would have the Hong Meng Immortal Qi for now. He had not even gotten his hands on it, so it was pointless to dwell on that.
