Wife is Fierce, Don’t Mess With Her! - Chapter 867: Huo Yingcheng, Yu Bao'er (39)

In a world of brooding heroes and dark justice, one mercenary stands out—not for his skill, but for his relentless sarcasm and love for chaos. A self-proclaimed anti-hero, he finds himself working with the Titans, much to their frustration. While undeniably skilled in combat and nearly impossible to kill, his real talent lies in driving his teammates insane with endless jokes, fourth-wall breaks, and questionable decision-making. Whether it’s swapping Robin’s gadgets with toy versions, turning serious battles into slapstick comedy, or giving monologues mid-fight, he thrives on pushing everyone’s patience. But beneath the humor, there’s a sharp mind, a tragic past, and a surprising willingness to do what others can’t. While the Titans may roll their eyes at him, they also know that when things get truly dire, he’s the wildcard they need. Love him or hate him—he’s here to stay, and he’s having way too much fun.

After breaking up with his girlfriend, he accidentally acquired a genius system and rose from there against the heavens, becoming invincible..

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.
