Chapter 187: Formidable Immortal Dao Enemy, Peril of the Supreme Sect

Inside the cave.

Zhang Buku gripped the stone axe, swinging it continuously. His moves were fierce, his footwork profound and mysterious, leaving behind lingering images.

At first glance, it looked as if several clones remained within the cave chamber.

Ever since he had arrived at this cave and learned the Heaven-Splitting Divine Axe, he hadn't gone out again.

By cultivating the Heaven-Splitting Divine Axe, his Qi-Blood rapidly grew stronger, and he had completely integrated with the mysterious power of the Demon Core.

He hadn't noticed that a sparrow was watching him from atop a distant rock.

Watching Zhang Buku's form, Gu An felt gratified.

This kid actually has some talent!

At least he hasn't let down the cultivation I've given him!

Gu An also noticed that Zhang Buku's bloodline was changing, and this change wasn't evolving towards the Six-Headed Jiao Luo, but another type of demon qi he had never seen before.

He suddenly thought of the Fierce Demon.
