He had been studying the two monumental works written by Wang Baoyu. Though he did not want to admit it, the theories within were basically correct.
Plant-type martial soul masters were best suited to absorbing soul rings from plant-type soul beasts. That could maximize the enhancement of the martial soul's essence and might even allow it to evolve.
He guessed that Wang Baoyu's Blue Silver Grass martial soul had been able to evolve continuously because he had followed this path, even evolving his Blue Silver Grass into a tree.
So, it would be best for him to hunt plant-type soul beasts for soul rings, but another problem now stood before him.
After so much cultivation, he could now roughly withstand a hundred-thousand-year soul ring. Yet finding a hundred-thousand-year plant-type soul beast was harder than reaching the heavens. He had never even heard of one existing.
Among low-level soul beasts, plant-types vastly outnumbered animal-type soul beasts. Yet at higher levels, plant-type soul beasts were exceedingly rare.
The disadvantage of plant soul beasts was simply too obvious. They could not move on their own and could only passively endure attacks, becoming food for many soul beasts or targets hunted by human soul masters.
Forget hundred-thousand-year plant soul beasts—even fifty-thousand-year ones were difficult to find.
Previously, when seeking his sixth soul ring, he had failed to find even a twenty-thousand-year plant soul beast.
He could not help regretting it once again. If he had not followed Teacher's arrangements and chosen those animal soul beasts as his soul rings, but had selected plant-type soul beasts from the very beginning, he would not be so conflicted now.
At the very least, his first five soul rings could have been plant-type. That would have given him a sufficient foundation, and even if his eighth and ninth
