After the Jade Spirit Branch, there were no new high-rank spirit plants about to mature within the spirit field.
Although the "Sixth-rank Phoenix Tree" had entered its mature phase, it couldn't mature in just ten days or half a month. Using three-grade Nascent Soul Grass Beads to hasten its maturity would require using up a large portion, but Lu Xuan was quite patient, quietly waiting while occasionally extracting a strand of Origin Yang True Fire from the bead to speed up the growth of the Phoenix Wood.
Additionally, the Five White Bone Killing Sword Grass, the Spectral Splitting Shadow Sword Grass, and the Sha Yuan Fruit from the Underworld Spirit Field had all entered the maturing stage, and the harvest of light clusters was imminent.
Therefore, Lu Xuan shifted his focus to improving the spiritual seeds.
He placed the condensed Earth Fire Heart Lotus Seeds together, slowly baking them with the Pure Yang True Fire he had cultivated.
