486 Two Immortal Gu obtained!

"I want to see you refine the Gu personally." Fang Yuan had a thought as he asked the question to probe the land spirit.

The refinement process of Gu Masters were secretive. If someone saw them, the recipe might leak out or even expose the Gu Master's unique methods.

"Of course, this was one of the agreements." Lang Ya land spirit agreed immediately, out of Fang Yuan's expectations.

Fang Yuan raised his brows, having a slight understanding.

Back then, when Long Hair Ancestor failed in refining space escape Gu, he wasted all of the materials that Thieving Heaven Demon Venerable had collected for his entire life. Among them, many Gu materials were extremely rare and Thieving Heaven Demon Venerable only managed to get them out of pure luck.

Thieving Heaven Demon Venerable was a rank nine Demon Venerable, to repay his losses, as well as saving his reputation, Long Hair Ancestor agreed to refine Gu for him.
