When he took action, residents of some cities near Heiyun Mountain could vaguely see black clouds rolling in the direction of Heiyun Mountain, with faint fire and thunder flashing. They could also faintly hear some thunder.

An hour later, an unprecedented fire broke out in Black Cloud Mountain.

The fire stretched for three hundred miles and burned the huge Heiyun Mountain into a wasteland. From then on, there was no trace of the demon in Heiyun Mountain.

It wasn't until half a month later that a demon that escaped from Heiyun Mountain was captured by a human demon-slayer master while doing evil in the surrounding cities.

From this demon's mouth, I learned that half a month ago, a human demon slayer named Su Xin broke into Black Cloud Mountain single-handedly. Relying on his profound and powerful Taoist techniques, he killed the Black Cloud Mountain Demon King and many big demons.

They were all killed, and only some of the little demons managed to escape.

With his own efforts, he completely wiped out the demon paradise of Black Cloud Mountain!

Chapter completed!
