He undergoes a total transformation to emerge as the most fearsome and powerful fiendish demon in his era, that even immortals and fiends are fearful of him, and saints are at his beck and call.
Mastering the Supreme Demon Classic is the turning point in his life. He is able to unleash his immense and divine power from within, illuminating the entire universe!

The Age of Celestials has arrived.

In the world where Vincent was sent into, the existence of Celestial Beings greatly stimulated the advancement of humanity. With their help, the humans started breaking out of their shackles as they exceeded the limitations of their mortal bodies.

They have passed down mana cultivation techniques and various combat arts increasing their strength as they fought against the true enemies of the world…

However, as Vincent was sent by his grandfather to complete a very unusual mission, he learned that these majestic Celestial Beings weren’t gods or existences out of his reach… They were actually tools or weapons that humans have been using for their own greed. More than that, he discovered the true origin of the Celestials!

Hence, with the help of his System, he mounted a rebellion…

I am the sword.

Killing a man amidst a thousand miles, no one dares take ten steps.
Killing a man amidst a thousand miles, no one can take ten steps.
Killing a man amidst a thousand miles, ten steps? Not possible!

I am the sword, the sword is me,
On the path towards heaven, each shall wield their own.
