Chapter 135: Refinement, Breakthrough

In the spacious room, Lu Yun looked at the black wooden piece in front of him with delight.

The Pure Yang Aura surged out and quickly enveloped it.

Following the method of refining pills and spirit grass, Lu Yun began refining the mysterious black wood piece.

As expected, soon, the room was filled with a flickering green light, and a powerful energy burst out from the black wood piece, gradually being converted into energy values by Lu Yun's refinement.

"I've indeed found a treasure this time."

Feeling the rapidly increasing energy values on the panel, Lu Yun was ecstatic and, at the same time, increased the output of the Pure Yang Aura to speed up the refining process.

As it was refined, the black wood piece gradually revealed its true appearance.

The whole piece was green, with faint ripples on the surface, reminiscent of a lake with splashing waves. As the refining process continued, a faint fragrance filled the room.
