Fate Online: Shadow - Chapter 1: I Am Back!

Klein’s greatest wish is to transmigrate to another world and live life in an isekai, just like in anime, manga and novels. However, fate is on his side and the typical truck that the main characters always carry in isekai runs over Klein. But, to his bad luck, he lived a few more days in the hospital and, just on the day he died, Klein heard a ⟨⟨-DING-⟩⟩ that he knew it meant. That was the day of his death, but also the beginning of his adventure into another world.

Mission: Transmigrate world by world into a scoundrel’s body; clean up the original’s life.

Wei Mingyan is a liar, through and through. But he doesn’t see himself as such. His motto? “If one deceives others for a lifetime, then all lies would become the truth.”

Jiang Jiuqing is the princess of a vanquished nation. No one knows her extreme cleverness hidden under her ordinary skin——she also doesn’t want others to know either. Staying out of things is her manner towards handling affairs, and wanting nothing is the norm in her life. However she has a white moonlight. After not seeing him for many years, he has now completely blackened, causing trouble everywhere——The world’s number one lobbyist, the peerless and magnificent Young Master Ji Yu.

Jiang Jiuqing had always thought that the reason why her white moonlight is a white moonlight is because he has forgotten about her, and will never belong to her. He is her master, and she assists him in lobbying the world. They are just allies, a symbiosis relationship, mutually using each other.

A long, long time later, Ji Yu said——

“This world is frantic and absurd. Malicious people die an ugly death, and the merciless people are sought after. I was never reluctant to leave until I met you.”

There are thousands of people in the world, and thousands of beauties, yet it is only you who can disturb my heart.

Are you ready to fall in love with the smartest and most cold-hearted people in the world?

The calm and cool-headed princess of a vanquished nation x the ruthless and revengeful number one lobbyist.

Male and female leads are both very strong, white cuts black.

“White cuts black” = someone who looks very gentle on the outside, but in fact, is actually very ruthless and two-faced

To the jerk who wasn’t faithful, she’ll draw a premature death talisman for him. For the poisonous step mother, she’ll send a death flower. For the step sister who is two faced, she’ll personally rip off that fake pretty face!

But when she personally offered up her body to her nemesis because of a child who she had no fate with, something unexpected happened. The night of the big wedding, the groom changed and a cold and luxurious man pushed her down. “You can marry whoever you like, but you can only give birth to my children!”
