One Piece: The Template System - Chapter 22: Whiskey Peak - 2

On Christmas day, seemingly overnight, God summoned everyone on Earth, giving every single person a 'Gift' along with a System.

These Gifts, synonimous with special abilities granted people powers beyond comprehension.

However, with these abilities came tragedy that enveloped the world. The Apocalypse!

Jeremy Lewis, a reclusive loner, is mysteriously exempt from this phenomenon and finds himself being the only one without a Gift.

God decides to grant him the last Gift available, [Subspace], and forcefully returns him to a world that has become hell.

Horrifying monsters now lurk around every corner, and inevitable death awaits.

Arming himself with his wits and the Gift he possesses, how will Jeremy survive this cruel new world that he finds himself in?

“Everything will go according to plan, and ultimately the path I have started will lead to my victory... these tools will be useful in achieving that!”

In a future timeline, the earth was visited by a species known as the Slarkovs.
Having lost their home planet and in search of a new one, earth was the next habitable planet for them.

Humans and Slarkovs made a deal with each other in return for the Slarkovs living on earth.
The Slarkovs traded their technology and knowledge for a new home.
They were similar to humans except for some of them who had slight differences so fitting into the society wasn't a problem.
Over the years Slarkovs and humans began to mate with one another and reproduce offsprings.
This in turn created a new species known as the mixed-blood.
Centuries later mixedbloods could tap into their bloodline and perform unimaginable feats.

Gustav born into an age where bloodline determines everything, struggles to fit with a useless bloodline.
His bloodline only grants him the ability to change his hair color, destroying his hopes and dreams for a great future.
His fate is turned around when an unexpected situation leads to him finding a system that grants him the power to unlock and upgrade bloodlines by completing quests but he's baffled by two quests with a five-year deadline. Success will grant him unimaginable rewards...
But only one thing awaits him if he fails... Death!

Follow Gustav on his interesting journey filled with unprecedented adventures, danger and death, maybe?

The end of the world is coming, the world has undergone great changes, and everything has changed. Plants, animals, and even insects, as long as there are living things, have mutated.
Become more powerful, and even evolved supernatural abilities, such as chickens and ducks that can fly to the sky, such as cats and dogs that can breathe fire.
But only humans, without any obvious changes, seem to have fallen from the top of the food chain to the bottom of the food chain overnight.
Any creature that can open its mouth to eat can treat humans as food.
But fortunately, this world has not completely killed humans. Gradually, humans discovered that they had the ability to cultivate compatibility with other creatures.
As long as it has a high degree of compatibility with some powerful mutant creatures, it can be used for its own use to achieve the purpose of protecting itself.
Fang He is a person who is very compatible with mutant animals, but it is also because of his ability that he has changed from the strongest to the stupidest.
Fang He, who was reborn, said, “Hmph, this time…”
