MTL - My Master is a Bug - Chapter 69 1st Qualifying Tournament

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.

There are a total of seven sins, and a revelation is made to a young man named Alex that he is destined to become a demon lord, more especially a demon lord of sin called LUST.

It's not like he can change that and because he always knew something about himself was different—not in a physical sense, well, maybe a little—and not in a mental sense—but rather because he is thrown into a demonic war that compels him to accept his new reality.

He was only aware of a difference in himself. Relating to him and the ladies who are drawn to him... Well, it was more or less like he was a magnet in front of all the girls, and all the girls were drawn to him like a metal.

System: Want to live? Want to recover from illness? Want to change Da Zhou’s fate? You only need 998 points to redeem a package guaranteed to cure all diseases and strengthen the body! You don’t need 2400 points, also don’t need 1200 points only 998 points. You won’t suffer losses or be fooled! Welcome to the system of the king of the dead…..

Ji Jinrong: This name does not sound very auspicious

System: Don’t pay attention to these details /(ToT)/ ~~

Ji Jinrong killed all his brothers. At the age of thirteen, he dragged his sick body to the throne and worked conscientiously as a puppet emperor in the hands of the courtiers and eunuchs. Everyone says that the great general Wei Tingjun has wild ambitions, and is intentionally revolting however, Ji Jinrong felt that Wei Tingjun was not staring at the throne but at him, who was sat on the throne!

Ji Jinrong carefully tempted: “If I die you can be the emperor.”

Wei Tingjun: “You dare die, I’ll have everyone buried with you!”

Ji Jinrong: “…..”

See, it wasn’t his misconception.

So even if it was to just tie the head of the wolf, he (JYR) won’t die easily.

Ji Jinrong: It’s getting cold, its time to ruin the country. I (imperial) have to go back and look for (tie) the great general!
