Entertainment Life With A Camera - Chapter 123:

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.

The majestic master of Yunran, who is proficient in medicine, poison, and martial arts, lives happily like a fairy, but once he was struck by lightning, his soul turned into the bullied eldest lady of the Shangshu Mansion, and his life is not as good as a dog…

The step-sister regretted her marriage, and directly ordered someone to knock her unconscious and throw her on the sedan chair, and marry the man who was rumored to be suffering from eye and leg diseases.

*****

On the wedding night, Nangong Mo said to her:

“This king is blind and disabled and his life is not long. I don’t want to miss the beauty. You can reconcile and find another lover.”

Yunran replied affectionately: “People in the world often say that when you get married as a husband and wife, there is no doubt about your love. Now that you and I are married, we should never leave. I will accompany you to the last moment of my life.”

However, Nangong Mo heard her voice:

[Heli? Why do you want to reconcile? Living in your house, spending your money, and when you close your eyes and kick your legs, I will dig a hole and bury you, and then inherit your wealth, rich land and beautiful family, wouldn’t it be beautiful? 】

Nangong Mo gritted his teeth slowly: “Heh… very beautiful!”
