Thousand River Mystic Realm

"Thanks Martial Uncle Yun for the gift," Jiang Chengxuan promptly bowed to Yun Yizhen in gratitude, who responded with a smile.

At the same time.

Qin Shenwu took out a hexagonal crystal, its surface swirling with traces of lightning, from his possession.

Yun Yizhen's face showed surprise upon seeing this crystal.

"Void Thunder Crystal!"

A slight smile appeared on Qin Shenwu's lips.

"Am I that kind of a person who takes advantage of others?

Here, this Void Thunder Crystal is a welcoming gift for my disciple's Dao companion."

He then handed the crystal to Shen Ruyan.

Shen Ruyan looked towards her own Shifu, Yun Yizhen, who nodded with a smile,

"Accept it. This is a treasure of great benefit to us thunder cultivators.

It can help you better understand the rules of the void and thereby comprehend Void Thunder.

I suppose, Brother Qin, this must be the only Void Thunder Crystal you have left, right?"
