Death March kara Hajimaru Isekai Kyusoukyoku (WN) - Book 16 - 16-62. Parion Holy Land, Once Again

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.

Zhao Yelan was born as a criminal s*ave and was rescued by the Third Prince. After years of painstaking efforts to put him on the throne, Zhao Yelan became a sycophantic minister whom everyone detested, but he was actually given a marriage by that person to general Yan Mingting, the lone star of Tiansha.

The general caused the death of his father, his mother, his wife, and his dog. Everyone hoped that the general would kill Zhao Yelan as soon as possible.

On the wedding night, Zhao Yelan, who was dressed in red, took out a dagger, his eyes sharp: “What do you want?”

Yan Mingting held his hand tightly, and borrowed his dagger to carve a large character on the head of the bed – – Early.

“You’re weak and frail, get up early every day and practice horse stance with me!”

“?”

The common people thought this marriage was truly wonderful!

They heard that this big minister was beaten every day. He had to repair the roof tiles when the house leaked and also work in the kitchen. He served his husband and was very obedient, and from then on, he didn’t dare condemn people.

Hey, the general was truly mighty!

Zhao Yelan sat lazily by the bed, playing with the dagger, and raised the ends of his eyes slightly: “Where did these rumors come from?”

“From my dog’s mouth.” Yan Mingting, who was in horse stance, patted his thigh. “Madam, please take the seat of honor. You don’t have to get up early tomorrow.”
