First came a stream-like coolness and sweetness, which, when the Spiritual Energy of the Spirit Gathering Grass flowed through the meridians of the entire body...
was like the warmth of volcanic rock!
However, that warmth did not bring any discomfort to the body; on the contrary, it was quite comfortable.
Gradually, the Spiritual Energy began to converge on the already devastated vital organs.
The organs, riddled with holes, began to heal themselves at a visible rate with the enhancement of the Spiritual Energy.
Oliver Walker was not unaware that refining the Spirit Gathering Grass into an Elixir would increase its effects by at least tenfold, and even augment one's combat power on top of healing the organs.
It could even possibly lead to a breakthrough into the Grandmaster Realm, but...
He did not have that much time and had to squander such a heavenly resource.
