A wedding took place, and the richest man of Shencheng married a woman notorious for her bad reputation.Ning Guiwan was known among the upper class as a calamity—tormenting her sisters, causing her mother's death, leading an unseemly private life, despised by her father, and cast abroad to fend for herself.Four years later, she returned and directly took hold of Shencheng's most esteemed man's arm to enter into marriage, leaving the whole city in shock.However, amidst the doubts, Ning Guiwan presented a post-marriage agreement to Quan Yu, with the last clause reading: beyond cooperation, there shall be no involvement with each other.Quan Yu pinched the girl's waist, his lips curving into a smile, “You start the game, but I decide how to play it.”……Everyone said that Ning Guiwan, relying on the favor of the Quan Family's old matriarch, forced Quan Yu to marry her; otherwise, how could a man with such sound principles fancy a woman not only beneath his station but also with a scandalous past?But those who knew the truth shook their heads. Sound principles? Nonexistent. To get his wife, Mr. Quan resorted to all kinds of dirty tricks, even deceiving the old matriarch, yet Mrs. Quan, with her cold exterior and hard heart, married him but refused to love him.Until one day, Mr. Quan accidentally got injured, causing Mrs. Quan to frown.Then—“It's terrible, Mrs. Quan, the master has injured his arm, please come back and see him!”“It's terrible, Mrs. Quan, the master has injured his leg, please come back and see him!”“It's terrible, Mrs. Quan, the master...”“What happened again?”“The master says he's sick, please come back and see him!”“What sickness?”“The master says it's... lovesickness...”“……”[A pampering story, sweet to the extreme]

I woke up in my sleep, and a strange door appeared in my home…Behind every door is a strange world.

In the nightmare world, Jiang Cheng added the news from the strong man to the fat man, and he almost cried when he heard the latter, “If you die here, the whole family will stand upside down and bleed?”

“Is such that.”

“Then I don’t think you are too scared?” The fat man widened his eyes.

Jiang Cheng turned his head and said in a very formal tone: “Because I am an orphan.”

What happens when a scientist from a futuristic world reincarnates in a World of Magic and Knights? An awesome MC is what happens! A scientist’s goal is to explore the secrets of the universe, and this is exactly what Leylin sets out to do when he is reincarnated. Dark, cold and calculating, he makes use of all his resources as he sets off on his adventures to meet his goal. Face? Who needs that… Hmmm… that guy seems too powerful for me to take on now… I better keep a low profile for now. You want me to help you? Sure… but what benefit can I get out of it? Nothing? Bye. Hmmm… that guy looks like he might cause me problems in the future. Should I let him off for now and let him grow into someone that can threaten me….. Nahhh. *kill*-

Alternative: Leylin is transported from an advanced technological era into a medieval world— except there’s magic. Equipped with “only” his quick wits and an A.I. chip fused to his soul, he sets out to become the most powerful magus the world has ever known. In a land divided into the Light and Dark Magi, the weak can either be cattle or disposable slaves. Only the strong can determine their lives, and only they have the luxury for virtue. Yet strength is only a tool for Leylin, like any other. His goal, in the end, is his own.
