"Get 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 giving orders. Hey...it's not easy to take care of 24 kids at once. Press the gourd and lift the ladle. They haven't even reached the seven-step hand washing method yet. Just wearing a hat and a mask can make everyone...
He needed to correct it seven or eight times.
There is no way. Grete thought silently in his heart, these are ordinary people, they cannot be treated as well-trained medical students. They have no concept of aseptic operation, and they have to teach it from the beginning, be patient, be patient...
When an ordinary person wears a mask and squeezes into the subway, two or three out of ten people will pull down the mask. If you look closely, there will be three or four masks that are not airtight enough. Even when an epidemic breaks out, medical staff put on and take off protective clothing,
That also requires emergency training!
After finally teaching them the seven-step hand washing method, they passed the assessment one by one, and after teaching them how to put on and take off protective clothing, a whole morning passed. And that afternoon, when everyone put on protective clothing and prepared to officially enter the P4 laboratory, another
Another obstacle encountered...
"Meow~~~"
The black cat next to Linn took elegant steps, quietly walked to the door, and sat down quietly. He turned his head and looked at Gretel with his golden eyes without blinking, and his snow-white beard moved. The meaning was very clear.
:
I want to go in too!
"Um...Mr. Trocca, 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.
It makes sense, there is no need for him to scratch cats everywhere...
"Meow……"
The black cat turned to look at the airtight door, then turned to look at Gretel. Its tail snapped and hit the floor regularly. After a stalemate for a while, seeing that Gretel had no intention of compromising, a black light suddenly erupted, and the entire
The body suddenly swelled!
"oops!"
The students exclaimed. Grete also subconsciously took a step back and saw Mr. Troca transform from a black cat with white gloves about 20 to 30 centimeters tall and weighing only a few kilograms into a black panther in an instant.
.It was fierce and pressing forward, its chest was grunting, and its deep roar kept rolling.
Gretel: "..."
You dare to bite me? You dare to bite me?! And your roar is not right at all. Cheetahs, leopards, and snow leopards don't roar like this. I have heard the sounds of leopards, and they are very delicate!
"Troca!" Linn scolded from behind. The black panther raised his head and glanced at his master. His steps suddenly stopped and his body shrank back. In an instant, what appeared in everyone's eyes had turned into a delicate bird.
Petite little kitten.
"Wow……"
Behind Gretel, the boys and girls couldn't help but make sounds of being impressed. The black cat's body was only as big as a palm and could be lifted up with one hand. Its watery eyes took up almost half of its face. It had four short legs.
He was a bit wobbly when he drove and walked, making him look even more pitiful and cute.
Seeing the students crowded together and looking over, it rolled on the floor, revealing its white belly and four pink paw pads. Behind Gretel, the sound of breathing suddenly started one after another, and some students thought tentatively.
Request a favor:
"gentlemen……"
Gretel: "...Don't act cute, I won't let you in even if you act cute! You haven't disinfected! You don't wear protective clothing! If you are not allowed in, you are not allowed in! Get out! Mr. Lin En!"
Next to the black cat, a bone hand suddenly descended and scratched at the head.
The black cat jumped up, climbed onto the high platform, crawled under the table, jumped on the faucet, and turned into a bolt of lightning at the entrance of the laboratory. However, the bone hand was obviously very experienced and pursued it closely. After a few rounds, it actually pinched it.
The black cat's scruff lifted into the air.
Behind the bone hand, bones clicked and flew over on their own, and soon they formed a golden skeleton. He walked out slowly, rounded his arms, and threw the black cat violently:
"Meow ouch ouch ouch ouch ouch -"
The black cat's shrill cry gradually faded away. Gretel breathed a sigh of relief and quickly gave the order:
"moss, close the door!"
The main door of the laboratory closed quietly. Lin En came over sheepishly:
"Um... I'm sorry, cats always look like this. Although Troca is a demon pet, when it turns into a cat shape, it takes on the nature of a cat. By the way, can this skeleton come in?"
"...Can we come in? Skeletons are easier to wash..."
Alas, if skeletons can be controlled remotely to perform precise operations, there is really no need for magicians to enter and leave the P4 laboratory in person, wear protective clothing, take off protective clothing, shower with potions, change clothes and rinse. In this way, necromancers and dangerous biological experiments,
In fact, they are a perfect match?
It's a pity that controlling skeletons is a long-term goal after all. Gretel's current work still relies on magicians and magic apprentices to do it themselves. For several days, Gretel walked around the laboratory, correcting the apprentices' various mistakes.
Wrong behavior:
"Beef paste
"Don'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 absorb the culture solution! Who told you to pour it directly into the petri dish? Change the culture solution and try again! You still put the culture solution bottle next to the mouth of the petri dish, are you afraid that there are not enough bacteria?!"
"Hands! Hands! Don't touch the operating table with your hands! Have you forgotten the sterile operation?!"
"Open the lid of the petri dish and use a microscope to look at it? Who taught you?! All the bacteria fell into it! - If there are too many bacteria, the result will be useless! It will also contaminate the lens!"
Ah - I'm just a clinician, not a biology major! I'm not even a laboratory major!
Why do I have to endure so many things that I shouldn’t have to endure... I haven’t done the bacterial culture experiment many times in my previous life...
Grete looked up at the sky in pain. However, he lamented and lamented, teaching still needs to be taught. Only when they are taught can they be used as tools, right?
To be on the safe side, Gretel did not choose those deadly infectious bacteria. He did not even choose Staphylococcus aureus in case any student got careless and scratched himself and caused infection. Instead, he carefully removed it from his own freezer.
A vial of E. coli was prepared, cultured, multiplied, and distributed to the students:
Come on! Let’s do bacterial culture, propagation, and staining experiments!
This bacterium is not very lethal. Even if the protection is not in place, the worst thing is that students should wash their hands before going out and again before eating!
The students were overwhelmed with learning. After training in bacterial culture, bacterial staining, and microscopy, Grete began to train them non-stop to make culture media:
"Trim the fat off the beef! It must be trimmed! Don't leave any!"
"Wash the sea pebbles! Don't be reluctant to use water! Which temple do you belong to? You should wash them more carefully. The oyster shells are all stuck on them!"
"Add sulfuric acid! Pour it down slowly and be careful with your hands! Remember to test the pH, the test strips and comparison chart are given to you!"
A group of mage apprentices and priest apprentices rolled up their sleeves, trimming the beef fat, boiling the beef, and rinsing the sea stone flowers. Every day, they carry the smell of salt, blood and strange fragrance, and work hard.
I have no love in my life...
"I asked, are we working in a restaurant?"
"Maybe?...I've never done anything in the mage tower..."
"I didn't even have it in the temple..."
"Well...we, the apprentices, are the ones who help us add food to our temple, kill chickens and ducks...but it is a pity that the fat needs to be removed from good beef..."
Several boys from the Temple of the God of War replied in a low voice. Such beautiful snowflake beef can only be eaten by high-ranking knights and bishops in their temple! If you put it in the Mage Tower, not only can you not eat it, but the fat must be removed first!
The four apprentices of the Order of the God of Nature lowered their heads and said nothing. They did a lot of work: turning the soil, fertilizing, pulling weeds, taking care of poultry and livestock, cleaning up excrement... there was no shortage of farm work.
Are temple priests more noble than others?
nonexistent!
After struggling like this for half a month, the students' operations finally changed from jerky to proficient. Less and less things were wasted, and Gretel's scoldings became less and less. Finally, Gretel announced that the first phase of the exam would begin:
"Let's test our learning results! - Starting from making the culture medium, everyone operates the entire process independently, completing the culture, isolation and microscopy of fecal E. coli!"
"ah……"
The 24 students were up and down, wailing. It looked like they had skipped class for half a month, and the teacher suddenly informed the students that they were going to take the exam. Grete looked at the bitter faces with a smile, and clapped his hands:
"If you make it, there will be rewards~~~"
"What if it can't 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 to go back to where you came from..."
This threat not only made everyone nervous, but even Master Lin En also followed Alexander. He made a set of utensils by himself, washed the seaweed, boiled the beef, added acid and alkali, filtered and removed the residue, and did everything meticulously step by step. Around him,
Golden Skeleton also made a set of things and followed the exact same operation, seemingly trying to create a double insurance.
However, even so, Master Lin En still failed to finish it first. While he was still preparing the dye and preparing to dye the bacteria, the group of students already raised a hand high:
"Mage Nordmark, I'm ready here!"
Grete walked over quickly. Looking under the microscope, the thick and short shape of E. coli with flagella was clearly visible under the microscope. He smiled with satisfaction and wanted to pat the student's shoulder, but when he raised his hand halfway, he still couldn't.
He held back and just patted him with the mage's hand:
"Yes, yes, you did it right! What's your name? Which organization are you from?"
"My name is Leon Carlos, from Black Crow Swamp, sir." The apprentice bowed and his voice was clear. Through the protective clothing and mask, Grete couldn't see his expression, but he could hear the joy in his voice.
, almost a little excited. Gretel's mood also became cheerful:
"Very good! The third update tonight - ah no, starting tomorrow, you can help me and we can start a new project!"
*****
I found out how to make agar agar, but it’s hard to find out how to make beef extract... I read a lot of papers, and all I found were to add ginger powder, allspice powder, nutmeg powder, white pepper... to make beef extract for culture media.
How is it done?
