The Hero Age— circa 3113 ad. An age where humans have developed superpowers such as superspeed, superstrength, and every cliche superhero power there is. But not everyone awakened superhero powers.

A tad 1% of the population were unawakened and Satoshi is one of them... or so he thought.

It all started when he wished for a System-like ability in front of a retro computer, which in turn granted it the power of the System. What Satoshi didn't know is that he holds the power to transform/evolve animals and inanimate objects.

How will Satoshi's life evolve after this newfound power? Will he finally be the very best like no one ever was?

He was the continent’s strongest and most revered alchemist, Ye Zifeng. He was under one person and above millions. However, due to an unpredictable event, he had died. After his rebirth, he had become the supertrash of the Ye family and suffered disgrace. To make matters worse, he had an argument with his fiancé that led to the break off of his engagement. In this second life, he will work to change his own destiny. He vows to return to the peak of the world, trample on those who laughed at him and rewrite his legacy!
