Doctor Goes Back to Joseon - Chapter 171 - Chapter 44

He is an undead who is devoid of all humanity, he is the one and only supreme overlord, he is a man who has severe mysophobia.

There are many people who try to act cool in front of him, whatever soldier king, assassin, system user, transmigrator, reincarnator, the strong returning, the strong coming down from the mountain, person coming back from the immortal world, reincarnation of the devil king, immortal emperor possessing someone’s body, and so on, all of them do not know what will happen next

When I cleared the final chapter of a game that was a national failure, I became an unnamed side character in it.

A non-standard, unmeasurable, EX rank supporting character.

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.

I have seen and heard my share of rags-to-riches stories, and many of them claimed that they had started from 'junkyards' and slowly grew to be where they were right now.

From Zero to Hero, they declared.

You can do it too, they said.

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

I call bullshit.

Life doesn't work like that.

To pass as an imperial concubine, one must be professional.

Actually, the profession of an imperial concubine is pretty good. The emperor will accompany you in eating and drinking, and even pay you for it. What’s not good about that?
