I Secretly Develop Myself In The Demon World - Chapter 595 - 318: The Memory of the Demon Beast

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?

To care for her ailing sweetheart, college student Lu Chenchen gave up her white-collar office job and chose the higher-paying caretaker profession instead. Going around in circles, she ended up at the Mao family’s home.

The Mao family background was complicated. Old Madam Mao was not her son Yanning’s birth mom, but his young aunt. His wife was Old Madam Mao’s first love’s daughter, spoiled and pampered. Despite over ten years of marriage, husband and wife were distant.

To repay Old Madam Mao’s kindness in raising him, and for the sake of his three children, Mao Yanning endured again and again – not just a loveless but outright destructive marriage.

Lu Chenchen walked on eggshells among these people – carefully serving young and old, currying favor with the lady of the house without offending the man of the house, while also worrying about his sweetheart’s illness and missing “his” elders and children back home. Her heart was like a cookie flattened between the pages of life, living a difficult and cautious existence.

However, as the saying goes, “You reap what you sow.” A life that has been polished will eventually shine with a brilliance that ordinary years cannot compare.

Starting over once more, he has entered this “living game” again in order to control his own fate.

This time, he will not be controlled by others.

Massive wars, life advancement, entering Godhood, sword reaching to the peak; a legend of a man becoming a Sword God has begun.
