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.

Battle of Mount Hyjal:

The overwhelming Burning Legion, Malfurion on the front line saw his death as his own.

Outside the barracks at the rear, Li De leisurely started his singing.

A spectacle composed of countless terracotta figurines rises from the ground!

“Building Wonders: Terracotta Warriors.

Spectacular effect: All combat units are upgraded by one level! ”

“This…is this the power of a demigod?”

Malfurion clenched his fists and asked in disbelief.

“You’ve become stronger, send it quickly!”

Li De said, but what he thought in his mind was:

“What’s the best way to build the next spectacle?”

This is a story of a traveler with a spectacle system, farming in the world of Azeroth, and blooming the light of civilization.
