It's not that hard to open a hospital in another world, right?

Chapter 291 Come To My Room At Midnight Tonight
"Wear your hat!"

"Wear a mask!"

"Line in line, come and watch me wash my hands! - You! Pull up the mask! Cover the bridge of your nose! What about you!"

Gretel kept ordering.Cough... 24 hairy children, it's not easy to take care of them at once, press the gourd to float the scoop.He has not yet reached the seven-step hand washing method, and he needs to correct it seven or eight times just for wearing a hat and a mask.

no way.Gretel thought to himself, these are ordinary people, they should not be treated as well-trained medical students.They don't have the concept of aseptic operation, so they have to teach themselves from the beginning, be patient, be patient...

Ordinary people wear a mask to squeeze the subway, two or three out of ten people can pull off the mask, and if you look carefully, there are still three or four masks that are not airtight enough.Even when an epidemic breaks out, medical staff need emergency training to put on and take off their protective clothing!

After finally teaching them the seven-step hand washing method, they passed the assessment one by one, and then taught them how to put on and take off the protective clothing. It has been a whole morning.And that afternoon, when everyone put on protective clothing and was about to officially enter the P4 laboratory, they encountered another obstacle...

"Meow~~~"

The black cat beside Lynn walked to the door quietly with graceful steps, and sat down quietly.Turning his head, his golden eyes looked at Gretel without blinking, and his snow-white beard moved.The meaning is very clear:
I want to go in too!
"That... Mr. Troka, you can't go in." Gretel raised his hand to signal everyone to stop, bent down, and discussed with the black cat.Fortunately, this black cat is intelligent, can speak human language, and can negotiate well. There is no need for him to scratch cats all over the place...

"Meow……"

The black cat turned to look at the airtight door, then turned to look at Gretel, its tail flapped and flapped regularly on the floor.After a stalemate for a while, seeing that Gretel had no intention of compromise, a ball of black light suddenly burst out, and his whole body suddenly swelled up!

"oops!"

The students all exclaimed.Gretel also took a step back subconsciously, and saw that Mr. Troka transformed from a black cat with white gloves that was [-] to [-] centimeters tall and weighed only a few kilograms into a black panther in an instant.He was menacing, pressing forward, rumbling in his chest, and the deep roar kept rolling.

Gretel: "..."

How dare you bite me?How dare you bite me? !And your roar is not right at all, cheetahs, leopards, and snow leopards don't bark like that. I've heard the voices of leopards before, and they're so delicate!

"Troka!" Lynn yelled from behind.The black panther looked up at its master, then suddenly stopped walking, shrinking back in size.In an instant, what appeared in everyone's eyes had turned into a petite kitten.

"Wow……"

Behind Gretel, the boys and girls couldn't help themselves, and made a sound of being cute.The black cat's body was only the size of a palm, and could be lifted up with one hand. Its watery eyes almost took up half of its face.The four short legs strode forward, walking a little shaky, making her look even more pitiful and cute.

Seeing the students crowding each other and stretching their heads to look over, it also rolled on the floor, revealing its white belly and four pink paw pads.Behind Gretel, the sound of breathing suddenly came and went, and some students tried to ask for love:

"gentlemen……"

Gretel: "...Don't be cute, I won't let you in if you are cute! You are not disinfected! You are not wearing protective clothing! If you are not allowed to enter, you are not allowed to enter! Get out! Mr. Lynn!"

Beside the black cat, a bone hand suddenly descended and scratched at the head.

The black cat jumped up, climbed onto the high platform, drilled into the belly of the table, dived into the faucet, and burst into a bolt of lightning at the door of the laboratory.However, the bone hand was obviously experienced, and he pursued closely. After a few rounds, he actually pinched the black cat's nape and threw it into the air.

Behind the skeletal hand, pieces of bones rattled and flew over by themselves, and soon formed a golden skeleton.He walked out slowly, swung his arms round, and threw the black cat out violently:
"Oooooooooooooooooooooooow-"

The black cat's shrill cry gradually faded away.Gretel breathed a sigh of relief, and quickly ordered:
"Moss, close the door!"

The main door of the laboratory was quietly closed.Lynn walked over embarrassedly:
"That...sorry, cats always look like this. Although Troka is a magic pet, but it has become a cat, and it has the temperament of a cat. By the way, can this skeleton enter?"

"...Can I get in? Skeletons are easier to wash..."

Alas, if the skeleton can be remotely controlled to perform fine operations, there is really no need for the magician to go in and out of the P4 laboratory in person, wear protective clothing, take off the protective clothing, shower with potion, change clothes and rinse.In this way, necromancers and dangerous creature experiments are actually a perfect match?

It's a pity that manipulating skeletons is a prospect after all.Gretel's current job still depends on magicians—and magic apprentices, to do it by themselves.For several days, Gretel walked up and down the lab, correcting the apprentices for various wrongdoings:
"Beef paste should be cooked and cooked thoroughly!"

"You can't hold the petri dish with your hands! Put it back into the dirty pile and prepare to re-sterilize it! The bacteria on your hands will contaminate the petri dish, and the results will be inaccurate!"

"Use a dropper to draw the culture solution! Who told you to pour it directly into the petri dish! Change to another petri dish and start over again! You still put the culture solution bottle on the mouth of the petri dish, is it because you are afraid that there are not enough bacteria?!"

"Hands! Hands! Don't touch the operating table with your hands! Have you forgotten the aseptic operation?!"

"Open the lid of the petri dish and use a microscope? Who taught you?! Bacteria have fallen into it! - Too many bacteria, and the results will be useless! It will also pollute the lens!"

Ah - I'm just a clinician, I'm not a biology major!I'm not even from the lab!
Why do I have to bear so many things that I shouldn't bear... Bacteria culture experiment, I haven't done it several times in my previous life...

Gretel looked up at the sky in pain.However, lamentation is lamentation, teaching still needs to be taught.Only after they have been taught can they be used as tools, right?
To be on the safe side, Gretel did not choose those deadly infectious bacteria.He didn't even choose Staphylococcus aureus, in case some student scratched himself with a knife and caused infection.Instead, he removed a small vial of E. coli from his freezer, cultivated, propagated, and distributed it to the students:
bring it on!Let's do bacterial culture, reproduction, and dyeing experiments!

This bacterium is not very lethal, even if the protection is not in place, at worst, students should wash their hands before going out, and wash their hands before meals!

The students learned beyond their feet.After the training on bacterial culture, bacterial staining, and microscopic examination, Gretel started to train them non-stop again, training them to make culture media:

"Remove the fat from the beef! Be sure to remove it! Don't leave any fat!"

"Wash the sea stone flower! Don't be reluctant to use water! Which temple do you belong to? Wash it carefully, the oyster shells are all stuck to it!"

"Add sulfuric acid! Pour it down slowly, be careful with your hands! Remember to measure the pH, the test strips and the comparison table are given to you!"

A group of mage apprentices and priest apprentices rolled up their sleeves, skimming beef fat, boiling beef, and washing sea stone flowers.Every day, I smell of salt, blood and strange fragrance all over my body, and I can't live without work...

"I said, are we working in restaurants?"

"Maybe?...I've never done it in the wizard's tower..."

"I'm not in the temple either..."

"Uh... we apprentices help us to add extra meals in the temple and kill chickens and ducks... But it's a pity that good beef needs to be trimmed of fat..."

Several boys from the Temple of the God of War answered in a low voice.Such beautiful snowflake beef, in their temple, only high-level knights and bishops can eat it!Put it in the mage's tower, not only can't eat it, but also remove the fat first!

The four apprentices of the God of Nature Sect lowered their heads and did not speak.They do a lot of work: digging the soil, fertilizing, weeding, taking care of poultry and livestock, cleaning up manure... There is no shortage of farm work.Temple priests are nobler than others?
nonexistent!

After half a month of tossing like this, the students' operations finally changed from jerky to proficient, and less and less things were wasted, and Gretel's scolding sound became less and less.Finally, Gretel announced that the first stage of the exam will start:

"Let's test the learning results! ——Starting from the production of the culture medium, each person operates the whole process independently, and completes the cultivation, isolation and microscopic examination of fecal E. coli!"

"what……"

The 24 students were high and low, all wailing.That way, it was like skipping class for half a month in a row, and the teacher suddenly notified the students that they were about to take the exam.Gretel looked at the bitter faces with a smile, and clapped his palms:

"If you make it, there will be a reward~~~"

"Then why can't it be done?"

A feeble voice came from the back row of the crowd.Gretel smiled:
"If you can't do it, you can make up the exam. If you fail the make-up exam three times in a row, I can only ask you where you came from and where you are going back..."

This threat not only made everyone nervous, but Master Lin En also followed Alexander.He made a set of utensils by himself, washed sea stone flowers, boiled beef, added acid and alkali, filtered and removed slag, and did it meticulously step by step.Beside him, the Golden Skull also made a set of things, and followed the exact same operation, as if he wanted to fight for a double insurance.

However, even so, Master Lynn still failed to complete it first.When he was still preparing the dye and was about to dye the bacteria, the student group had already raised a hand:

"Master Nordmark, I'm fine here!"

Gretel walked over quickly.Looking under the microscope, Escherichia coli looks thick and short, with flagella, clearly under the microscope.He smiled in satisfaction, and wanted to pat the student on the shoulder, but held back his hand half way up, and just patted him with the hand of a mage:
"Not bad, you did the right thing! What's your name? Which organization are you from?"

"My name is Leon Carlos, from Black Crow Swamp, my lord." The apprentice bowed and saluted with a clear voice.Through the protective clothing and mask, Gretel couldn't see his expression, but he could hear the joy in his voice, almost jumping for joy.Gretel's mood also brightened accordingly:

"Very good! Three nights tonight—ah no, start tomorrow, you help me, let's start a new project!"

*****
I have found the method of agar, but it is difficult to find the method of making beef paste... I have read a lot of papers, and I have to add ginger powder, five-spice powder, nutmeg powder, and white pepper... to make beef paste for culture medium How did it work?
