The Strongest Magic meets the Mightiest Mecha.

I have stolen Golden Mechas from the deepest vaults of the most tightly guarded fortresses in the world.

I have personally destroyed more armies than the top three superpowers have in the span of the Absolute War - combined.

I burned down the terrorist megacity of Habon.

I was expelled from the Union of Heroes at a younger age than people are allowed in.

I have talked to Ancient Gods, loved women, and devoured mechas that would make superpowers cringe in fear.

I have faced demons head on in moonless nights others fear to speak of during the day.

I am deified in a thousand cultures, and labelled as the devil incarnate in the rest.

I am the Mecha Emperor.

You may have heard of me.

Excerpt from Chapter 1

This is where it all began.

A junkyard.

Oh no, this isn't your clean, mechas-only junkyard that was the 'starting point' of many mecha geniuses out there.

As long as you work hard, everything is possible, they claimed.

I call bullshit.

Life doesn't work like that.

Traversing into another world, Zhang Xuan finds himself becoming an honorable teacher.

Along with his transcension, a mysterious library appears in his mind.

As long as it is something he has seen, regardless of whether it is a human or an object, a book on its weaknesses will be automatically compiled in the library.

Thus, he becomes formidable.

“Emperor Zhuoyang, why do you detest wearing your underwear so much? As an emperor, can’t you pay a little more attention to your image?”

“Fairy Linglong, you can always look for me if you find yourself unable to sleep at night. I am skilled in lullabies!”

“And you, Demon Lord Qiankun! Can you cut down on the garlic? Are you trying to kill me with that stench?”

This is an incredible story about teachers and students, grooming and guiding the greatest experts in the world!
