Five hundred years into the future, animals and plants had mutated into powerful beasts which endangered the human species.

To deal with the situation, the Federal government decided to build academies dedicated to mecha piloting. It marked the beginning of the Mecha Age.

With the help of the mechas, humans would gain the power to fight on equal terms with the beasts.

Years later, Peter was recruited by one of the mecha academies.

He thought that would be his path to become a successful pilot.

However, due to some circumstances, he was only able to choose another course…

The Genetic Warrior course.

As the world was invested in mechas, everyone knew that there was no future for a Genetic Warrior.

The basic concept the circled around Earth was that a human could never defeat a beast without the mecha’s help.

Fortunately, Peter managed to activate a special Divine-Grade Genetic Extraction System.

“Ding! Ant genes detected. Extraction in progress…”

“Ding! Extraction successful. Your strength has been increased by 100 times.”

“Ding! Grasshopper genes detected. Extraction in progress…”

“Ding! Extraction successful. Your leaping ability has been increased by 100 times.”

“Ding! Eagle genes detected. Extraction in progress…”

“Ding! Extraction successful. Your vision has been increased by 100 times.”

“Ding! Thunder God genes detected. Extraction in progress…”

On that fateful day, a mighty Genetic Warrior was born.

He was able to deflect a missile with his flesh and punch a hole in any mecha. He could even destroy a whole planet if he wanted to.

Su Xiao is a cold-blooded teenager who’s seeking vengeance for the death of his family, yet things ended up badly for him.

As he was taking his last breaths, he heard a voice calling him from dimensions, it was a strange system reaching him, asking him if he wanted to be saved, to be Reincarnated.

He just needed to accept a contract, Su Xiao didn’t have any choice but to do so, but he didn’t know what he signed up for!!

But Su Xiao wasn’t any ordinary Contractor, Su Xiao was a Hunter!
