After that, Qiu Tong worked hard to earn a lot of money and became the richest person in City A. The three children also went from gloomy little devils to bright little angels. They even referred to her during their interview. The jaws of the executives dropped when they saw the interview. "These children look exactly like the President!" "President, bad news. Your children are looking for a stepfather for their mother!" Before long, Qiu Tong was brought to the magnificent palace where a handsome man was waiting. "You want to run away now after stealing my seeds?" "What do you want then?" "I want your heart in exchange." Qiu Tong: Charming looks and exceptional character. Off-the-charts martial arts skills and a minor expert at money-making. Eldest Child: Male, genius in chemistry. Second Child: Male, extreme martial arts skills. Third Child: Female, their mascot in her little cotton-padded jacket. A highly-intelligent and skilled hacker. Jin Yang: S Country's President. Handsome and cold-hearted. He was set up to have a one-night stand with Qiu Tong. He only found out later that she kept the children.

"I, Eddie Edward, had reincarnated into a world of magic and became the single child of Duke Eddie from the Lancamdo Kingdom. Fortunately, I was given a system that could collect energy from magical items and turn them into attribute points, skill points, and bloodline points to enhance myself. Knowing that this is a world full of danger and cruelty, I’d decided to become stronger with the help of the system. On a day like any other, I was given a personal maid. The new maid was acting strangely, but I paid no attention to her weird personality because she was loyal to me. As days passed by, I began to have more maids around me. However, all of them were strange. It wasn’t until later I noticed that the maids would leave at night and return reeking of blood. Naturally, I was curious, but I’d never questioned them as they were my personal maids. To become stronger, I, Eddie Edward, continued to grow using the system to be not threatened by others in the future. Until a fateful day… I learned something important. One of my personal maids was a Fallen Angel? And the other one was the Lady of the Dark that was being pursued by the Holy Church? Not only that, but I also heard some of my maids being addressed as the Lord of the Dard? The Ominous Witch? The Vampire Queen? Lady of the Death? Why did their names sound like they were some antagonists of a novel? Could it be that all of my personal maids were actually the bad guys of the world I was in? Not long after that, I was now a wanted person in the Lancamdo Kingdom? Some even began to hail me as the Lord of Evil? Eddie Edward let out a deep sigh. “Fine. Looks like I can drop the act now.” With a wave of his arm, the alliance of the mage and knight was wiped out with an asteroid. “To tell you the truth, I’ve already become the God of Magic.”

Before there ever was a boy that ever lived in a cupboard on Four Privet Drive, there was a similar boy in a far worse home that lived on Spinner’s End. We all know the tale of that abused boy who grew up to become a bitter spy. But not all tales end the same for in the many parallel worlds that exist in the universe there are far better endings, and equally as many worse ones. This is a tale of one such condemned universe that for better or for worse chooses to change its own fate at through the sacrifice of the bitter spy.

This is a therapeutic romance novel that mixes psychology and science fiction. Lu Jia'er is a professor in psychology who is able to read the minds of anyone in the world. One day, she meets a special man, a legendary genius in the IT world rumored to be ugly—Jin Xiangdong. In fact, he's not ugly, and it's love at first sight for Lu Jia'er. This is compounded by the fact that she can't read his mind. To figure out what's so "special" about him, Lu Jia'er accepts his invitation to join an artificial intelligence research team. In her spare time, she would pursue him. She: "Can I chase after you?" He considers for a few seconds. "It wouldn't be easy!" She: "That's what I call a challenge!" He gives her a friendly reminder. "Time is precious. Don't waste it." Turns out that he was right. Not only is he difficult to chase, but he is also mysterious. When the secrets slowly unravel, what kind of ending could it be?

This is a Naruto/Naruto Shippuden/Boruto fanfic. It is possible that the MC might venture into other worlds but that depends on how everything goes. By the way, this novel will feature a system but before you start rioting, this system will not feature any bloodlines or summonings or anything like that. It's gonna be from one particular series, and the series in itself is going to be weaker than naruto so don't expect an OP mc from the start. There's gonna be a lot of training too.
