A Hospital in Another World?

The black mist surged downward.

Garrett's eyes lit up. He took two steps forward, then two more steps forward. He walked to within two or three meters of the edge of the formation, reaching out to touch the black mist. The thin mist flowed through his fingertips, slightly damp...

Does it feel like a mixture of Cloud Mist Technique and Plague Fog? It’s somewhat similar to my spell concept?

Beside him, Aishe Moon Song coughed forcefully. With a flick of her hand, a wisp of fresh air surged out, tugging sharply at Garrett’s sleeve.

Garrett snapped back to reality, noticing for the first time the people kneeling on the ground, some glaring at him with angry eyes. Because it was during the god-worship ceremony and he was an outsider mage, they couldn't jump up and attack him. Even so, their faces darkened, and their knuckles cracked loudly.

Garrett smiled apologetically and quickly retreated. He backed away to where Cirilla and the others stood, closed his eyes slightly, and extended his mental power to sense the magical fluctuations in the black mist:

It seems, well, it does resemble a plague spell, but there’s something different about it?

Hmm… maybe the difference lies in the distinction between the god's power to activate the vaccine and the magical activation of the vaccine...

Garrett closed his eyes, carefully analyzing and comparing it with his spell model and the techniques he remembered from the Plague Maiden. On the other side of the square, a group of mages had also set up instruments and were busy:

"The type of magical fluctuation… leans towards necromancy, sharing properties with the plague spell..."

"Detected something similar to divine power..."

"The intensity of the fluctuation… third ring, but the coverage area is more than ten times that of an ordinary third ring spell, making it very efficient..."

"Divine power tends to be cold..."

The black mist flowed out wave after wave. In general, a clay statue would be offered from the formation below, and a layer of black mist would flow down, lightly covering the crowd in the formation.

As the breeze blew, the black mist atop the pyramid opened and closed. Garrett seemed to see two snake women beside Chivacoatl constantly bending down to take things out and handing them to her. They were translucent, shiny, breaking one by one...

So each casting consumes one vial of vaccine?

Not bad!

In this way, more vaccines can be sold, at least recovering some development costs! Well, although besides labor costs, any other materials that the Eagle God’s Kingdom has are all provided by the Eagle God’s Kingdom...

Garrett continued to analyze and think hard. Beside him, Aishe Moon Song stared gravely at the crowd kneeling on the square and the continuously falling black mist:

"Plague… I smell the plague in the mist… this Snake God, I’ve seen before, is not supposed to be an evil god, so why..."

"Oh, that’s just the vaccine! Vaccines are also made from pathogens!"

Cirilla interrupted her doubts with a smile. The silver dragon girl sniffed the scent of the black mist again, turned to look at Garrett, her mouth curling up, eyes bright:

This is Garrett's invention!

Using Plague Fog for mass vaccination, gathering people together, and casting spells with a wave of the hand! It saves manpower, and resources, and avoids the need to transport large quantities of syringes and needles, preventing cross-infection…

Of course, the most important thing is having enough vaccines!

Garrett is the best!

In a place like the Eagle God’s Kingdom, without glass workshops or dwarf factories, relying on the little demon Goldie to make syringes by hand one by one, the efficiency is terrible… Plague Fog is much more convenient! Simple!

Only Bernard didn’t care about any of this. The barbarian shifted his weight from one foot to the other, bored, observing the surroundings of the square, indifferent to the subtle spell fluctuations in front of him.

After standing for a while, seeing that Garrett had no intention of leaving, he turned behind Appa, pulled out a large chicken leg, and started munching. He ate one himself, then gave one to Appa...

The Snake God's "blessing," or rather, the large-scale spell vaccination, lasted for a full two hours. Garrett stood nearby for two hours, analyzing spell fluctuations, taking notes, sensing the condition of the vaccinated, and was busy beyond measure:

"Unfortunately, there’s no way to measure antibodies; we can only use efficacy tests to determine if the vaccination is successful and if there’s any protective effect… if only there was a way to measure antibodies…”

He muttered. When the ceremony ended and people began to disperse, a group of warriors suddenly descended from the pyramid. They blocked several formations, leading them to a nearby alley. Soon, Garrett heard noises and cries coming from the alley:

“What’s going on?”

Curiosity piqued, Garrett moved closer to take a look. The formations consisted of either civilians, merchants, artisans, or the servants of nobles. They crowded into a large courtyard in a disordered mess, at the end of which a few mages were drawing blood with syringes one by one...

Drawing blood…

Right, drawing blood!

Garrett's eyes lit up. To measure antibodies, there’s another method:

Inject blood with antibodies into the patient to see if the patient can gain resistance.

Of course, this method is very risky and can trigger a cytokine storm, so it can’t be used frequently. However, it can be tested on mice!

Right, Blood Identification Spell can be used extensively. Mice that haven’t been vaccinated, and those that have been vaccinated;

Rabbits that haven’t been vaccinated, and those that have been vaccinated;

Monkeys that haven’t been vaccinated, and those that have been vaccinated;

Humans that haven’t been vaccinated, and those that have been vaccinated!

Pile up the big data! If there’s a substance absent in unvaccinated blood but present in vaccinated blood, that substance must be the antibody!

Garrett rubbed his hands together eagerly. This batch was too late, but for the next batch, he would coordinate with Archmage Haines and the Snake God priests to ensure blood samples are collected before and after!

"Nordmark, you’re finally back!" The mages drawing blood saw Garrett outside, and someone immediately came over, grabbing him excitedly:

"Archmage Haines has negotiated with them, we currently need a large amount of vaccines, and our production is falling short! Fortunately, you’re back, hurry up and take charge!"

Uh…

Uh…

How many vaccines do you need… You’re not planning to accomplish everything in one go, are you? Vaccinating everyone in the Eagle God’s Kingdom, at least everyone in Tenochtitlan and around the Highland Lake, against yellow fever, are you?

This stuff isn’t like the cowpox vaccine, where a single calf under the White Horn King can provide enough vaccine for tens of thousands of people; yellow fever vaccines need to be made with chicken embryos. Have you collected all the eggs in the city?

At least leave some to hatch a new batch of chicks, don’t wipe out the chickens in the Eagle God’s Kingdom!

Garrett inhaled deeply, exhaled, and with a bright smile, grabbed Aishe Moon Song, pushing her in front of Archmage Jennings, who was overseeing the scene:

"Look! I’ve brought you a child of nature to help with vaccine production!"

Aishe Moon Song: ???
