Surprise! Tyrant's Little Crybaby Went on a Killing Spree After Being Reborn - Chapter 37

Amidst a disaster, an orphan contracts a sickness.

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?

have you heard of it?

If you turn on the music player in the dead of night, put on headphones, hide your head in the quilt, and listen to the looped single repeatedly.

Fall asleep after looping forty-four times. If you are unlucky and open your eyes again, you will no longer be lying on your own bed, but will enter a strange space that is completely isolated from reality.

That space… On the surface, it looks like the places we usually see, such as our bedroom, living room at home, underground garage, bathroom, basketball court, construction site, etc. But if you look closely, you will find that it is different. …Everything is different.
