The Ten Thousand Poison Grass itself contains potent toxins, using these wasted pills, which are infused with erysipelas, to cultivate them is indeed a perfect match.
As for the remaining ones, he either threw them to the Spirit Dog or gave them to the Gold-Devouring Spirit Bee, or the Golden Armor King Flying Cicada.
Demon Beasts and Spirit Insects, with their thick skins and strong digestion, might find these wasted pills harmful to humans, but they're full of Spiritual Qi, which is beneficial to the Demon Beasts and Spirit Insects.
As long as it's not excessive, they can be quickly digested and absorbed.
Moreover, Zhou Changwang never expected his Earth-penetrating Dog to have significant growth potential; reaching the Mid Stage of Qi Cultivation is already quite remarkable.
Even if erysipelas accumulates and prevents further advancement, it's nothing to be concerned about.
The Gold-Devouring Spirit Bee is even more similar in this regard.
Its potential is relatively low.
