Nobody cared if Minghe helped the Human Tribe. However, when the Cultivation Tribulation ended, and the Human Tribe became the major tribe in Untainted Land, every Sage would consider Minghe as an eyesore.
Every Sage would want to fight for the Luck of the Human Tribe once it became the major tribe. When Goddess Nvywa created human beings, she had primordially occupied 30% of the Human Tribe's Luck, while Suiren-Shi, Youchao-Shi, and Ziyi-Shi would get 5% respectively for finding kindling, building houses, and making clothes for the Human Tribe.
The remaining 50% of Luck would be the target of every Sage. If Goddess Nyuwa didn't make any effort for the Human Tribe, she would get less and less Luck and there would be more left to the other Sages. As for the three Ancestors of the Human Tribe: the Suiren-Shi, the Youchao-Shi, and the Ziyin-Shi, their Luck would remain only if they didn't do any harm to the Human Tribe.
