Chapter 137: Owe a Favor

"Hmm?"

As Chen Feng surveyed the herbs in the storeroom, he suddenly felt a rich aura emanating from the depths of the space.

He quickly followed the scent to its source.

To his surprise, he discovered a ginseng hidden within a secret compartment, weighing a full three taels, with roots neat and orderly, looking much like an old man.

That strong aroma of spiritual energy was, indeed, emanating from this piece of ginseng.

"This is not just any Hundred-Year Ginseng, this ginseng is at least one hundred and fifty years old..."

Chen Feng was overjoyed.

With the increase in medicinal age, the spiritual energy becomes more refined, and it is not merely a linear growth over time.

Only Centennial Herbs can be called rare medicinal materials, and the spiritual energy of a single piece of Centennial Herbs is at least equivalent to ten fifty-year-old herbs.
