The sea of ​​clouds is misty, the sky is infinite. Who among all living beings does not yearn for it? The way of heaven is illusory, no one can see it. In this world, who does not want to live forever? The resentful couple of three lives and seven lifetimes, the grievances and hatreds between the righteous and the evil sects for thousands of years. One person, one ancient sword, how will he face the whole world...

It begins on the mountain.

With the glint of a knife, a flash of steel in the hands of a sworn brother. A betrayal.

Stabbed and pushed down the mountain, Zi Chen lied within the red-stained snow, left to die.

This is where it begins; he is given life by lightning,

baptized by thunder.

Those who had once betrayed him should all suffer in his cruel revenge.

One night a mysterious and unexplained phenomenon occurs in the nine provinces. Five years later Chu Feng, a regular outer disciple of the Azure Dragon school, awakens one of the mysterious nine lightning beasts. And discovers an egg sealed inside him.

From there we follow Chu Feng on his path of cultivation.
