When Yun Yi was born, he was regarded as the greatest threat in history.

He brought the unknown and fear, and was also seen as a terrifying existence that surpassed all superhuman concepts.

When he was a year old, Slayer Tyrant discovered Yun Yi at the interstellar border and adopted him as his adopted son. The young Superman became Slayer Tyrant’s sharpest sword, conquering all directions and sweeping all directions. Wherever he went, he would be subdued.

Slayer Tyrant was furious because he was worried that the Goddess of Death would look at Yun Yi, so he decided to completely wipe out his soul.

When he was twelve years old, Yun Yi personally killed his adoptive father, Slayer Tyrant.
