Chapter 568 Encounter Heavenly-luck Flower Again

The first auction was scheduled for a month away. Lin Yun had some of his men go and gather information about precious natural resources, while he spent most of his time cultivating.

Previously, he traded for many martial arts-related treasures. Even though many of them were of no use to him, quite a few were indeed helpful.

"Boom booom booom——"

In one practice room, Lin Yun was quickly absorbing strands of spiritual energy from heaven and earth, while using various natural treasures.

As the days went by...

The one who made the most progress was Xia Qingqing!

You get what you pay for!

The Heavenly-Luck Heart, truly a priceless rare gem of heaven and earth!

In a month's time, Xia Qingqing's mental strength advanced from the middle level of ten to the peak of level ten!

Though it was nowhere near as rapid as upgrading through the Cosmic Trading System, it was still impressively extraordinary!
