Chu Yang dug up the Feathered Flower Grass and went back to his room, where he sat cross-legged and started to refine and absorb the Spiritual Energy contained within the Feathered Flower Grass using the "Mortal Cultivating Immortal Technique."
Streams of Spiritual Energy dispersed from the Feathered Flower Grass, entering Chu Yang's body.
Then, he refined and absorbed it, turning it to his own use, sinking it into his dantian.
The level of Spiritual Energy contained in the Feathered Flower Grass far exceeded Chu Yang's expectations.
Chu Yang had thought it would take about an hour to refine the Feathered Flower Grass.
But the result was somewhat surprising to him.
The process of absorbing and refining the Spiritual Energy of the Feathered Flower Grass lasted for three hours.
In other words, the richness of the Spiritual Energy in the Feathered Flower Grass was three times what Chu Yang had previously estimated.
As a result, Chu Yang's strength grew by leaps and bounds.
