The greatest drawback of the Ten Thousand Beasts Melting Furnace Technique was that when fusing with Demon Beast Essence Blood, one would be eroded by the violent, bestial will within, risking "Beastification."
She had been troubled by this before. The Vein-Protecting Pills could only guarantee that her physical meridians wouldn't be damaged, but the risk on a spiritual level remained a huge, hidden danger.
But now, with these Spirit Grasses, the problem was solved!
As long as she refined enough Purifying Heart Jade Dew Pills, she could maintain maximum mental clarity while practicing the Evil Technique, at least until she reached the Fifth-Grade, greatly reducing the risk of Beastification!
Moreover, the speed at which she refined Demon Beast Essence Blood could also be boosted to another level!
A wave of joy washed over Gu Yuexi.
'Not bad. This chest of Spirit Herbs and Elixirs is actually very useful.'
