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.

Yin BiYue has made the worst purchase ever. After transmigrating countless times into the bodies of canon fodder villains, he buys a ‘Fiend Halo’ from the Rebirth Company, supposedly the best aid for an up and coming final BOSS!

He’s ecstatic to finally get a villainous role where he won’t die after just a few lines, if any at all, and is raring to become the best opponent a protagonist will have… However, why was everyone looking at him with pitying eyes? Why was the protagonist rushing over to help him get out of his crimes? Most importantly, why was his ‘Fiend Halo’ just making things worse?!

Meanwhile, the intern salesperson at the Rebirth Company discovers that he might have accidentally sold a prototype White Lotus Halo to a certain villain…

What kind of experience is it to travel through time and become an AI?

Li Wenyuan, who was hit by the meteorite, successfully experienced this feeling.

Fortunately, he discovered that the planet he controlled… seems to be a little bit special.

“Precious living metal? Any wall here is living metal!”

“Zello? You said that omnics don’t need this? Sorry, psionic machines are being produced.”

“Interstellar colony? Isn’t it good to build a ring world?”

This is a story of farming, and it is also a story of human exploration of the universe from the past.

There are space wars, interstellar adventures, civilization observations, and galaxy epics.

“So…” A few years later, facing the disaster that was about to sweep across the entire galaxy, the unmanned fleet controlled by Li Wenyuan stood up helplessly.

“They all think that I am a lost empire, and I can only do what the lost empire should do.”
