Generally speaking, Empress Nuwa wouldn't care about the growth of the ordinary merit.
As one of the four emperors of the Demon Race's most glorious era, the Holy Mother of the human race, and one of the Six Sages appointed by the Heavenly Dao, Empress Nuwa's status is exceptionally special. Every camp worships her with great reverence.
Moreover, Empress Nuwa never established a faith.
Amongst the Heavenly Dao's Six Sages, five established religions to fight for merit and Qi luck, yet Empress Nuwa held herself aloof.
It wasn't that she did not appreciate merit or Qi luck, the main thing was, Empress Nuwa's methods were a notch above the rest.
The other five Sages establishing religions was akin to starting their own businesses.
However, irrespective of the era, Empress Nuwa always received the original shares of the maximum corporation. She basically did not have to strive later, all she needed to do was share in the later dividends.
