Chapter 1004 Virus research, Gretel’s best experimental assistant (strong sea monster with ten thousand rewards)

"Sister Jasmine, when you went into the jungle, what method did you use to prevent mosquitoes from biting you?"

Before the Hawthorne couple set off to open a shop at the port, Grete saw them off and asked this question. Mosquito prevention and vaccines are two different technical routes and cannot replace each other:

If the vaccine is successfully developed, it can be 100%, or at least 95%, resistant to yellow fever. It is also cheap. According to Grete's estimation, after mass production, it can be priced at less than 1 gold coin per person, or even less than 1 silver coin;

If mosquito repellent can be 100% successful, it will not only protect against yellow fever. It can also prevent malaria, Japanese encephalitis, dengue fever, and Zika virus. This is beyond the reach of vaccines.

But it is expensive. Magical expulsion is too expensive, and ordinary expulsion methods are unreliable. Gretel also places his hope on other races, for example, whether the elves have any special methods——

"Mosquitoes will definitely not bite me!"

The half-elf landlady who came over with a plate of roasted rabbit tilted her head and smiled, cute and cute. She put down the plate, and Mr. Hawthorne immediately took over, cutting the rabbit legs one by one and putting them on the guests' plates.

Ms. Jasmine was lying on the back of her husband's chair, looking at his generous back, and smiled slightly:

"He is a bit more troublesome. We went on a mission together, but the mosquito ignored me at all, and chased him like a black cloud. He was so scared that he rushed into my tent - otherwise, I

How could you hit him with an ice pick?"

"Who knew there would be so many mosquitoes in that place!"

Mr. Hawthorne finished cutting the four rabbit legs and distributed them to Gretel, Cerira, Lynn and Bernard. The second rabbit's legs were distributed to Valensimo, Jasmine and himself. He picked up the dinner plate and put them

Both rabbit carcasses were poured into Bernard's plate.

After handing back the plate and watching Jasmine leave the table briskly to take down a dish, the former mercenary nicknamed "Firestone" shrugged and looked back at his wife tenderly, his ears a little red:

"Isn't it generally true that the farther south you go, the hotter the weather, the more water, and the more swamps there are, the more mosquitoes there are and the more poisonous they are! Who knew that so far north, the mosquitoes are like exploding, like a black cloud?

Come to me!"

He demonstrated to everyone with gestures:

"Aren't mosquitoes usually buzzing, buzzing, buzzing, and you can just hear them buzzing, but you can't see where they are? One can buzz for half a day, and two can buzz for a whole night?"

Gretel nodded. Mr. Hawthorne's voice suddenly rose to a higher pitch, and he finally remembered to tilt his head slightly to prevent his saliva from spraying onto the dinner plate on the table:

"That's not the place! I saw that the momentum was not going well, so I took off my big-brimmed hat and slapped it on my face. Oh my god, the sound on the hat was crackling! It was like a hailstorm! With a touch of my hand,

It's thick and greasy, like a layer of mud..."

Grete's head exploded when he heard this. It's not like he has never traveled in the Black Gate Peninsula or walked through the wilderness, so he has never seen such a spectacular mosquito. However, beside him, Bernard and Barensimo nodded together:

"It's like that in some places."

"It's like this in the north. Some places have no mosquitoes, and some places have a lot of mosquitoes. Not only are they numerous, but they are also big and dense!"

So that's it... Gretel thought for a while and shuddered: Fortunately, he didn't encounter such a scene. He asked curiously:

"Then what?"

"Then I panicked." Mr. Hawthorne sighed:

"The back of my hand hurts and is a little numb - forget the pain, numbness is not a good sign; the hat is covering my face, crackling, and I can't see anything. I just try to fan and fan,

When I saw a little bit of mosquito-free space in the gap, I rushed over!"

"And that place without mosquitoes is my tent." Mrs. Hawthorne came over carrying a large, deep earthenware pot and placed it in the middle of the long table with a bang:

"There aren't even pigs or sheep in this place... I'll tell the caravan later to bring some more piglets and lambs. There are also cows, how can we live without steaks! Do you eat crocodile tails every day?"

Lifting the lid of the pot, it turned out that it was a big crocodile tail, together with several stewed crocodile claws, simmering hot in the pot. Ms. Jasmine took matters into her own hands, filled a bowl full for Grete, leaned over and pushed it to the pot.

In front of him:

"Back to the question just now, mosquitoes will not bite me, but they will bite them. So in the wild, I will pick some flowers and plants, crush them up and apply them on them... Which flowers and plants? There are different flowers and plants in different places.

!”

This half-elf, plant master, nature's darling, smiles and takes it for granted:

"I don't know what their names are... Take a walk and see which plants mosquitoes don't approach, and see which plants animals roll on to avoid mosquitoes. Why don't you just use them? What's so difficult about this?

?”

"Uh...this..."

Gretel was sweating profusely. Serira on the left and Valensimo on the right all turned their heads silently and squinted at him from the corners of their eyes:

Looks like someone is a level 10 nature priest?

It seems that someone is also nature’s favorite?

It seems that someone should walk around in the forest, chat with flowers, plants, and trees, and then they will naturally know what plants should be used to repel mosquitoes?

So why do you have to ask others about this kind of thing? After asking, others will point out the route, why can't you just follow the plan?

"Cough, cough...→_→"

Gretel lowered his head, filled his mouth with a spoonful of crocodile soup, and then coughed violently. After coughing, his tearful eyes looked at Ms. Jasmine accusingly:

"Sister Jasmine, what did you add to the soup?"

"A little spice!" Ms. Jasmine replied confidently:

“The taste of crocodile meat is so strong, it won’t taste good without adding spices!”

Grete lowered his head obediently and picked out the spice seeds from the soup one by one. Ms. Jasmine sighed, turned around and poured a glass of ice water for him:

"Okay, I know you want to find a cheap way to save adventurers from mosquito problems. Back to the port, we will also send a task to ask them to bring some plants from the jungle and help you identify them one by one, okay?

good?"

"Then...then I'll put a bounty on the mage tower!" Gretel geared up:

"Senior brother came over this time and repainted my badge! I have another amount of money in my account!"

"No need..." Ms. Jasmine smiled and waved:

"We are already cooperating with the council to identify the plants used in mosquito repellent equipment. Don't worry, we also want to get it done as soon as possible - when the first batch of adventurers arrive, it is best to have something useful so that they can get us money.

Get stuff done!”

It would be best if the council was responsible for repelling mosquitoes. Gretel sent the Hawthornes away and plunged into his own work. We need to work hard to repellent mosquitoes and provide vaccines!

"Ah - what exactly should the vaccine be made of?"

Grete passed through the experimental area of ​​the institute - to be precise, the subject detention area, and came to the research area. Different from the experimental area, the research area strictly followed the standards of the P4 laboratory, with three areas and two passages, each one airtight.

Door.

Different from Gretel's previous life and the hand-made monkey version of the laboratory when Gretel first arrived in this world, in this P4 laboratory, every wall, every ceiling, and every inch of space above and below the laboratory are

Shrouded in anti-teleportation magic:

If you want to get out, you must go through the passages in the polluted area - semi-contaminated area - clean area, and strictly disinfect them one by one. Not to mention the wizard, not a single mosquito can even think of flying out!

Whether it's opening any door, teleporting, or entering and exiting through stone walking, jumping in fire, jumping through lightning, etc., don't even think about it!

Well, what happened last time, where someone sneaked into the core area of ​​the laboratory with a [Shadow Leap] and caused earth-shaking things, will never happen again...

Gretel took a bath, changed clothes, put on protective clothing, applied a bubble spell on herself to maintain fresh air, and applied a [cold and heat resistant] to prevent sweating. Emma, ​​without magic, she really can't stand it in this outfit...

He took a big breath, sealed the protective suit, and walked quickly inside. He squatted in front of the experimental table, faced a refrigerator with test tubes blessed with blood preservation spells, held his chin in one hand, and frowned:

"First of all, how to isolate the virus... You can't directly inject human blood into animals... Which part of the blood is the virus in? Blood cells? Serum?"

The answer to this question is actually very simple. A centrifuge spins quickly to separate the blood cells and serum of yellow fever patients. The blood cells are injected into a healthy person and the serum is injected into another healthy person to see who will be infected.

Helpless, Gretel did not expect this when he verified the infection method previously. Now he has to go back and capture two more healthy people to verify, he...

Gretel touched his moral integrity, a little reluctant to let it break to this point. There is no other way, just go a long way!

"Oniakim!" he shouted:

"Start the centrifuge at 3,000 rpm for 3 minutes to separate blood cells and serum! Dilute them 10 times with normal saline!"

Onejin went to work with a click.uuReading www.uukanshu.com Gretel

Looking at them with envy:

I don’t have to wear a protective suit, I don’t have to endure the dirty air, and I don’t have to sweat profusely in protective clothing. I’m so happy!

"Skeleton No. 1! Take 20 mice and inject 0.5 ml of blood cell diluent intraperitoneally into each mouse!"

"Skeleton No. 2! Take 20 mice and subcutaneously inject each with 0.5 ml of blood cell dilution solution!"

"Skeleton No. 3... Intraperitoneal injection of serum diluent..."

"Skeleton No. 4...subcutaneous injection of serum diluent..."

"Skeleton No. 5! Take 20 rabbits..."

All the injection experiments were completed in one go, and the experimental animals were moved to a special area to wait for special personnel to guard them. Gretel waved his hand:

"Okay! The experiment is over, O'Neajin, take everyone out!"

The skeletons collectively turned back, lined up, and left the contaminated area. Gretel was busy for a while, went out to take a breath, rinsed, and took off his protective clothing.

Emerging from the wet rubber protective suit, when he turned his head, he saw the boss in the corner next to the door, a bucket of disinfectant water, the water surface was rippling, and there were a dozen skulls piled under the water...

"Onegold!" Gretel held his forehead while having a headache:

"If there are not enough buckets, just tell me and I will make new ones! You don't need to take apart the bones, all the skeletons are piled in one bucket!"
