Refining a Celestial Kings' Heart

Ling Han took a step forward, and started to channel his Origin Power. At the same time, he also displayed his Regulations, especially the Nine Heavens Flame that was burning with vigor.

The large black dog started to form hand seals again, controlling the colossal giant in the sky.

The colossal giant's chest started to glow.

Pu!

A blazing fist-sized rock then flew over from his chest.

This was the colossal giant's heart. It had been incredibly large before, yet after being refined by himself, it had now shrunk to the size of an ordinary fist.

Xiu!

The blazing heart was as quick as lightning as it flew toward the large black dog.

If it had been any other Immortal Palace Tier elite, they would have definitely been penetrated by this shooting heart. However, the large black dog had been a Celestial King before, so he still possessed some extraordinary abilities even though his cultivation had already fallen.
