Chương 1539: Gale Celestial Stone Pill

"Easy? You're saying that the Meridian Heaven Heart Pill is easy? H-Ha! Truly shameless boasting!"

Ning Siyu was utterly speechless. She really did not know where Ye Yuan's confidence came from, to actually be this arrogant.

Meridian Heaven Heart Pill was a middle-grade rank three divine pill. Furthermore, it was a very difficult to refine type among rank three middle-grade divine pills.

Ning Siyu's talent was extremely high. One should not look at how she was young. She was already a middle-rank Three-star Alchemy God.

This Meridian Heaven Heart Pill was precisely the medicinal pill that she failed to refine for a long time.

This medicinal pill's refinement difficulty was immense. Even if Ning Siyu's master refined it, he could only occasionally refine one to superior-grade.

One had to know, her master was a Four-star Alchemy God!

This cocky boy in front of her was actually so arrogant.
