System Mania! - Chapter 1: Unholy Countdown

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?

When Sang Xia bumps into her ex-boyfriend, he says furiously, “Sang Xia, there are so many women in the world. Call me a dog if I still like you!”

She turns around without any hesitation and suddenly, he barks from behind her.

The whole world knows how crazily in love Rong Zhan is with Sang Xia.

Someone asks, “Master Zhan, how does Sister-in-law deserve your love so shamelessly?”

Rong Zhan answers lazily, “Just that one reason…?”

He stares at a certain woman and laughs suddenly.

She’s left speechless. F*ck, does this man have any shame?

This is an interesting and fun story of an all-powerful gangster boss shamelessly pursing his wife.

One of the few self-cultivator who exist in this modern world; due to an unfortunate event, completely destroyed his body in an explosion. Using all his effort to save his primordial spirit, he ended up in an strange magical world and had to start all over again. From a fallen aristocrat to the Warlord of Chaos, this can no longer be summarise as legendary; this is the life of the God of War.
