Chapter 642 Blackwater Asterism Cave

In the Spirit Field, Lu Xuan carefully picked a vine that resembled a gigantic python from the Spirit Soil.

The vine was the Third-Grade Jiao Vine that he had brought over when leaving the Sky Sword Sect. A long time ago, from its Light Cluster, a fifth-grade Body Refining Technique, the upper part of "The Chapter of Cosmic Dragon Transformation," had emerged. Lu Xuan had always been thinking about the remaining parts.

"Unfortunately, it's just an ordinary third-rank treasure."

After harvesting the Light Cluster, Lu Xuan held the reward in his hands, expressing his slight disappointment.

However, he could understand that, after all, the Jiao Vine was just a Grade Three Spirit Plant, and when he planted it, he was already at the Foundation Establishment Perfect Realm, and his cultivation had even advanced to Core Formation by the time of the Light Cluster's harvest. The downgrade in cultivation when planting and harvesting naturally affected the quality of the treasure.
