Game of the World Tree - : GRAND WEDDING

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.

Lee Jin Woo once lived a dismal life.
He lived pitifully on a day to day basis in his five-pyeon studio filled with mold.

Then, one day, he died in a sudden fire.

When he wakes up, he finds himself inside a novel.
But there’s just one issue…
He had become the novel’s villain!

[Complete book is free] Ji Zhao, the descendant of the royal chef, is in the book! Became the cannon fodder ex-wife of the male protagonist in the first supplementary novel that she wrote a bad review on?

Vanity is vulgar and extremely vicious! Cuckold the male lead, bully the male lead’s family, and finally end up crazy!

Ji Zhao, who opened the plug-in, said that these are all small scenes, so don’t panic!

Let’s see her use grilled fish, snails, barbecue skewers… and countless other delicacies to turn the tables against the wind and reverse the situation strongly!

Picking up pheasants, picking up duck eggs, and catching fat fish, you will be lucky!

Build a house, open a shop, buy a house, and live happily ever after!

Smiling, Ji Zhao took countless money and prepared to do nothing, but found that the future chief assistant was getting closer and closer?

“You, you… why are you getting closer and closer?”

“Silly lady, I am your husband!”

“It’s just the ex-husband!” Ji Zhao said, poking his neck.

“Oh?”

The next day, Ji Zhao cried violently and kept begging for mercy.

“I was wrong, Master Chief Assistant!”

“Call me my husband!”
