Fake dating my enemy, The playboy billionaire - Chapter 13: Love is cruel

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?

An inexplicable danger lurks within the harbor, where numerous containers emit a pungent stench. Suddenly, crew members fell ill and began to wildly attack other people. The text that appeared out of thin air told her that this was a survival game.

Fu Anan thought that it was just a dream, and that she wouldn’t be affected by it once she woke up.

It wasn’t until the game told her: She would die if she didn’t follow the rules of the game. She would also die if she didn’t survive for at least thirty days in the game…

Unknown danger on the cruise ship; An isolated island that suffocates people; creatures inside the fog; Floods that engulf everything; Epidemic with no cure; Constantly collapsing lands……

How should one survive in various natural and man-made disasters, and in environments where resources are scarce?
