Himitsu – Kuro no Chikai - Chapter 2, Part 4 – Contract

Zhang Ruo Chen was the sole male heir of one of the nine emperors of the Kunlun Field. Ruo Chen’s father was known to all as the “Enlightened Emperor”, however Ruo Chen didn’t just leech off his status as emperor’s son. He proved himself to be a dragon amongst men, possessing a heaven defying body, and managing to cultivate to Greater Perfection within the Yellow Horizon Realm, at just the young age of 16.

But even though he stood at the summit of the younger generation and had a boundless future, he sadly died at the treacherous hands of his own fiancee at a young age.

Reincarnated 800 years later in the body of a young boy who shares his name, he found out his former fiancee already unified Kunlun’s Field and built the First Central Empire, and was now known as Empress Chi Yao… Empress Chi Yao—Her Majesty governed the mortal world and enjoyed prestige in all directions as well as an eternal life.

Zhang Ruochen stood outside of the Imperial Ancestral Temple, looking at the statue of Empress Chi Yao, and the flames of hatred burned in his heart. “After I practice for 13 years, I shall send the empress to her doom!”

- Description from Novelupdates

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?

A pill, a tiny capsule encased in a biologically harmless water-soluble shell; A shell whose very existence is a result of a century of research and technological advancement. A manmade synthesis of Chemicals and product of complex processes.

And in the end, a means to an end.

A way to deliver a concoction of other Chemicals for an agenda; Vitamins for nutrition, medication for treatment, or… perhaps more.

We trust that what we eat won’t do us harm, and trust that those who are responsible for its creation had the best of intentions. But in the end, it is difficult or perhaps impossible to truly tell what lies within a pill.

That is until one day I entered a research institution as a test subject. All I did was swallow a pill I was told to be a health supplement.

Five years ago, after a car accident, Ye Fan fell from a demonic prodigy to an “idiot”!Five years later, on the same day, his seven older brothers and three uncles all perished on the battlefield, a family of ten loyal martyrs!At the funeral, Ye Fan's fiancée called off their engagement. The stunning sister-in-law declared on the spot, “If you didn't want to marry him, I will! I am willing to carry on the Ye Family line...”Ye Fan felt uneasy, “Sister-in-law, please don't. I'm really not an idiot anymore!”
