"Nine Yang True Fire, arise!"
Ren Feifan's palm shot out a flame that was extremely dazzling, and the tattoos on his arm flowed continuously, exuding a mysterious aura!
The emergence of the flame directly formed a strong surge in the magnetic field around Ren Feifan.
The surge lifted the Crystal Stone and suspended it directly above the furnace.
With a slight force of the Nine Yang True Fire, the Crystal Stone even showed some cracks!
The cracks spread continuously!
Countless Crystal Stone dust fell like petals scattered by a heavenly maiden.
Eventually, the Crystal Stone even began to rotate, reaching an extreme speed!
This kind of Crystal Stone, called the Thousand Soul Stone, was extremely hard on the surface and could not be pierced by ordinary strength, but it was very sensitive to flames.
Hence, it was used as a test!
To refine this stone, one must have extremely delicate control over flames!
But Ren Feifan had done it!
