"Grandma, what Gu is this?" The young girl curiously pointed at the central counter in the third floor.

There were three floors in this treehouse; the first floor sold Rank one Gu worms, the second floor sold Rank two Gu worms and the third floor sold Rank three Gu worms.

Naturally, the Gu worms that were put for sale in the treehouse were all rare and precious.

Gu Yue Yao Ji followed her granddaughter's gaze and saw a round bucket-shaped, tall and thin tree stump. The stump had five branches like five fingers of a human and were intertwined in the middle.

A sphere-shaped Gu worm that was thumb-sized was wrapped around by the fine branches and covered by green leaves, emitting a white silvery glow.

"This is a white silver Relic Gu, it can only be used once and can instantly raise a Rank three Gu Master's cultivation by a small realm," Gu Yue Yao Ji slowly explained.
