MTL - The Identity of the Real Rich Man Can’t Be Hidden - Chapter 151 they are fighting

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.

“How did it go?” Lily asked the next morning when Ava got to the living room.“Terribly.” Ava replied flatly, dropping into one of the sofas.Sarah entered almost immediately and sent Ava a teasing and wicked smile.“Really? That bad? Lucas is really great in matters of the bedroom. Did you do something wrong?”“Our little new concubine here is a virgin.” Sarah announced. Lily gasped and covered her mouth.“Oh God. That is not the kind of man you want to lose your virginity with,” Lily said.Sarah burst into laughter at Lily's comment.“It's not funny,” Ava scowled.“Actually it is. Better warm up to the idea because when Alpha Lucas Raventhorn wants to take you, he will in the roughest way possible.” Sarah advised.“You mean like last night? I thought he was going to rip you in half.” Ava rolled her eyes.“I like my men rough.”“Well, I don't.” Ava retorted.“If you are looking for flowers, love, and vanilla sex. You are a concubine to the wrong alpha.”“Ain't that the truth.” Ava murmured under her breath

It was a life without regret. My parents were in good health, and I wasn’t homey enough for me to combine my studies and part-time jobs.

Humanity’s first 8th Class Mage.

Betrayed, he traveled back 30 years into the past.

The story follows Ian Page, archmage and the first man to break through the 6th class, then through the 7th and become the most powerful mage, an 8th class mage.

After a lifetime of war and killing, the continent was finally unified thanks to his efforts. Now, old, his wish is to live the rest of his life in peace and try to find salvation for all the blood he spilled. However, his old friend, maddened by paranoia, couldn’t tolerate someone so powerful, so he betrayed Ian and killed him.

In his last breath, he cast a time magic that allowed him to travel back to when he was a young boy. With all the knowledge he previously had, he decided to do things better so he could end with less regrets.
