Kapitel 664: Chapter 637: Xing Zhou Design Diagram

By gauging the expressions of the three Heavenly Refinement Sect artifact refining masters, Xu Fan immediately knew he hadn't concealed the aura of a grandmaster of artifact refinement well enough.

There are aspects of excellence that unavoidably shine brightly. Xu Fan didn't intend for it, but it was what it was.

As the trio of artifact refining masters walked along the Rune Road, their expressions quickly turned respectful.

Upon reaching Xu Fan, they bowed immediately and said, "We pay our respects to the Grandmaster."

"You are guests, there's no need for formalities." Xu Fan said with a jovial smile.

In the Main Peak's Welcoming Hall, Xu Fan came to understand the purpose of the visit by the three Heavenly Refinement Sect elders.

"If you need assistance designing a few starships, this is simple, it's not worth the three elders making a special trip," Xu Fan said with a smile.
