However, things in this bizarre and strange world are not always as they seem, and, though it is a tremendous asset, the chip doesn’t always work as expected. With all of the crazy creatures and magical mayhem around him, one can only wonder what the future holds for this young man…

- Description from Novelupdates

I had a supporting role in a modern fantasy.

The loyal dog of a villain with an angel’s name, Cheon Sa-yeon, and an unfortunate supporting character who died on his behalf, Han Yi-gyeol.

In order to escape from Cheon Sa-yeon and survive, he must use the protagonist, Ha Tae-heon.

But Ha Tae-heon, who he thought of as a lifeline, was infinitely indifferent to him. Rather, Cheon Sa-yeon showed interest.

But besides that, something strange happened.

The events that occurred in the original story had advanced, and the gate and monster levels had risen. Even the people were “different” from the original.

The original version I was trying to use was wrong.

A Sky God’s Spiritual Foundation. It was the greatest natural treasure in all of existence, but the sacrifices one must make to gain the approval of such an entity was unimaginable.

Ryu is a genius amongst geniuses.

He was born with the four Grand Ancestral Bloodlines. The Lightning Qilin. The Fire Dragon. The Ice Phoenix. The Fire Phoenix.

He was blessed with an Ancestral Grade Bone Structure and Ancestral Grade Meridians. The Ice Jade Crystal Bones. The Chaotic Silk Meridians…

He was bestowed the First Ranked Heavenly Pupils. The Mysteries of Heaven and Earth Pupils…

However, none of it mattered. Born with a False Spiritual Foundation, it seemed that all of his talent would go to waste. Unless…

Unless he was willing to grasp his Fate in his own hands.
