Global Killing: Awakening SSS-level Talent at the Beginning - Chapter 13:

The story of an emergency room doctor dying from overwork and crossing into another world.

…

The sails of the great voyage have been unfurled.

The steam engine has yet to roar to life.

The glory of the Radiant Lord illuminates the continent, while across the sea, the churches of the gods and mages support the monarchy.

Dwarves freely roam the cities of the kingdom, and the legends of werewolves, vampires, elves, and dragons never fade.

In such an era, Wu Zhou, an emergency department doctor who died from working overtime, transmigrates into the body of Garrett, a young city guard.

Teammate: Oh no! The Captain is seriously injured, his intestines are spilling out!

Garrett: Help me up; I can still stitch!

Teammate: …What?

Garrett: …Apply a healing spell to where I stitched, let it grow… no, first apply it to the stitched layer, then the muscle layer, and so on.

Teammate: …What?

Garrett: Uh-oh, the healing spell is too fast, the stitches grew inside the wound!!!

When modern medicine meets magic and divine arts, what brilliant sparks will it ignite in this New world?

Garrett: Learning magic, mastering divine arts, expanding territories, and clashing with the church… whether you believe it or not, I just wanted to open a hospital.

Kay didn't have the best life. Most of it was fairly standard, but his past was marred by a tragedy that changed his entire world. Years later he had managed to mostly rebuild his life, and had started making something of himself.

And then he woke up in a different world. A world of fantasy and [Classes], a world much more dangerous than the one he'd been born in.

The new world he's been dumped into doesn't hold anyone's hand. Even with the bonuses that being an Outworlder brings won't keep him perfectly safe. One mistake could kill him in an instant.

But maybe, with a little bit of help, he could start over once more, and start to make something of himself again. And maybe, just maybe, that something he makes himself into could be amazing. And bloody.

As I'm leaning right now there probably will be sexual content later on, but I might change my mind later. There definitely will be death, gore, violence, and blood. Lots and lots of blood.

I changed my mind. No adult stuff in this story.

“VILLIAN!? Is that what you call me? Do you know what I have been through?

FATE dealt me this hand, and I'll find peace in it. Even if I have to end the world, I'll sit a king on its ruins.

I'm not a good guy. I won't even pretend that I am. But then again, who in this world can truly claim that title?

At least I know my heart. What about yours?”

Chiron lived an unfortunate life, but his problems only got started when he was reincarnated in his dangerous Hit novel.

Behold, a lesson to all authors... MC's have it difficult too.
