My name is Charlemagne Theron, yes, that’s right, that’s the Theron you think of, and Ajan Lor’themar is my younger brother. Don’t call me Daqiang, or I guarantee you will be beaten to three quarters to death. As a reliable time traveler, I will tell you responsibly, I… “Charlemagne, what are you muttering, today is the day when my younger brother will inherit the position of Ranger General, you don’t want to be used by Cirvanas and Vereesa Hurry up when the arrow hits your nostril.” “…Okay, my dear Alleria, here we go.” When the two walked away holding hands, an imperceptible figure appeared on the spot. “Brother, I wish you a happy Shura field.” I am Charlemagne Theron, I have led the people to participate in the orc war, defeated the ancient gods and the second fool, I also fought against the Burning Legion, and I have made contributions to Azeroth , I bring salt for myself. (PS: Don’t call me Daqiang, unless you want to grow an arrow from a certain key part behind you.) Book Friends Q Group 257692874

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.
