Chapter 171: Chapter 171: Grape Upgrade

In the underground space of Hidden Spirit Island, Xu Fan was standing in front of Pu Tao's main body.

With a pinch of the Five Elements Spiritual Fire hand gesture, Xu Fan gathered the five unique elements of spiritual fire. The power was ten times stronger than a single spiritual fire, just enough to reach the standard for refining Dao Tools.

Surrounded by more than a hundred upgrade materials, there were rare refined Spiritual Mines, natural Spiritual Treasures formed over tens of millions of years, and even unique, heavy treasures from the Vast Void Domain.

Although there were many treasures, at least more than half of them were sent by his Welfare good brothers, and they were the kind that couldn't typically be purchased by Spirit Stones.
