“Not energetic.”

"Meow."

“So boring.”

"Meow."

"Mr. Troca, you're bored, are you right? Lynn ignored you, right?"

"Meow……"

Serira squatted at the door of the institute boredly, holding the god-level cat-teaser - the golden feather of the eagle god - stretched in front of the black cat's nose, saying a word and shaking it.

Mr. Troca shrank into a ball in a slut, his eyes half open and half closed. Serera shook his feathers and stretched out his claws to pat him. He never stretched his claws, and he would never shoot the second one without hitting the shot, let alone stand up, or even jumped up to shoot:

Obviously, the golden feather in front had not been digested yet, so I had no interest in biting the second silk, and I just gave face to play with Miss Yinlong.

Serira swayed the cat stick, rubbed the cat's head, stroking the cat's back and tail, and scratched the cat's chin. She rubbed the black cat comfortably, squinted her eyes and collapsed into a cat's skin, and made a purr sound from her throat.

Serera simply carried it to his knees, rubbed his back with one hand and held the cat's belly with the other. A force penetrated from his palm into the black cat's body, helping it digest the power of the eagle god. While shaking it gently, complained:

"Grett is too much, right? He brought me so far away and didn't play with me! He was alone in the research institute! Just study it, he didn't allow me to stay by! He obviously asked me to stay when I was doing bacteria before..."

If Gret heard Cerra’s complaint, he would definitely complain that he was wronged. Can research bacteria and viruses be compared? Can the mutation iteration speed of bacteria and the mutation iteration speed of viruses be compared?

He didn't know - he had never memorized it in his previous life, and he had no way to recall it in this life - whether the yellow fever virus is a DNA virus or an RNA virus, a single-stranded or a double-stranded!

If unfortunately it is a single-stranded RNA virus, iterates quickly. You can lose something after copying it once, and copy it again and get some random things...

Just like the new crown, before Gret traveled through time, the thing had been iterated more than many times, and he couldn't even name it.

In fact, if it is not a very powerful and powerful variant, it will not be worthy of a name at all, and even the code name is not known...

Researching this kind of thing, especially to screen out the weaker toxic variants, iterate continuously, and find the weakest and weakest one that can only arouse an immune response but not endanger health. What is so great to give Cerra a stop next to you?

Gret had to send Serela out of the laboratory, rolled up his sleeves, and tested it himself. A row of test tubes from his belt was pulled out, and pointed it at the squirrel cage stacked in front of him.

Calm your mind and mobilize the [epidemic technique] in the meditation world to minimize the power:

"Seme No. 001! Go!"

The serum in this batch of test tubes is taken from the group of patients with the mildest condition - that is, they only have symptoms such as fever and headache. What? There is also mild proteinuria?

Sorry, normal urine and mild proteinuria are indistinguishable from naked eyes, and Grett does not have a laboratory test method for liver...

Of course, these patients have milder conditions because they have strong immunity or because the strain is weak. God knows this. Grett doesn't know that all he can do is to keep experimenting and constantly selecting:

Under the action of the disease surgery, the serum turned into a cloud and fog and rushed towards the mice. The cages were chirping and messy. Soon, the mice fell down one by one.

"Well...Next..." Gret took a deep breath, closed his eyes, and opened it again. In his meditation vision, the observation method was constantly changing:

"【Fate Observation Technique】! Well, mice No. 1, No. 4 and No. 8 have the mildest symptoms... Change the perspective! [Infrared Vision]! Yes..."

[Infrared field of view] improved from [Dark Vision], the observation range is smaller and the observation distance is closer, but the observation accuracy is higher and it is more sensitive to the difference in temperature. Gret squinted slightly and observed carefully:

The infrared field of view is deep and shallow. The nose is red, the body is darker; the abdomen is red, and the tail is darker...

However, if you compare the nose and head as the benchmark, it is indeed the No. 1, No. 4 and No. 8 mice, and their body temperature is slightly lower. Grey nodded and ordered the skeleton standing behind him:

"Skull No. 9, you measure your body temperature for each mouse and observe their condition. Every hour... no, measure it once every half an hour, and record their food, water consumption, defecation, mental state, whether they vomit blood, and most importantly, when will they die."

Skeleton No. 9 hit her teeth with a click, indicating her agreement. Grey nodded, walked to the next compartment, and pulled out another test tube:

"Seme No. 002! Go!"

It is undeniable that [Epidemic Technique] has greatly accelerated the research process - even if the incubation period of yellow fever is usually only 1 day, the effect can be seen immediately, and it is still very different from the need to observe and wait for a day before seeing the effect.

[Fate Observation Technique] + [Infrared Vision], you can see a rough idea immediately. As for the subsequent meticulous work, such as grabbing mice one by one, entering them, and pinching their mouths for three minutes...

This kind of skeleton is grateful for the diligent, hardworking, not afraid of being bitten by mice, and not afraid of being infected with plague and bleeding fever...

Gret tried hard to infect a group of mice with [Blood Disease], pick out the mildest symptoms, take the serum, and then infect the next group of mice. This repeated infection and iterative process, and soon, he felt that his control over [Blood Disease] had come to an end:

No matter how you reduce the power of [Bacteria Technique], it always has a lower limit. If it is below the lower limit, it is not to make an attenuated vaccine, but to fail to cast the spell.

In other words, relying on [Bacteria Technique], you will definitely not be able to get a qualified attenuated vaccine. At least, with Grett's understanding of this spell, he is currently unable to get it:

"That's sure!" Master Hines spread his hands. Facing Gret, who was sincerely asking for advice, this necromancer who had advanced to level 18 and was working hard towards the legend, looked as if he was right:

"Although I am not a branch of the plague, I have studied these basic spells. The disease technique cannot make people sick, and cannot make people sick immediately. What is the disease technique? Look--"

He outlined the spell configuration of [Bloody Technique], piece by piece, and told Gret:

"This part is used to target the types of diseases. If you want to get him infected with blindness, heartbrokenness, fever, cerebral fever, redness, swelling, tremor or nausea, all have different configurations."

The great wizard smiled ugly:

"Of course, after you proposed the theory of pathogenic bacteria, they also began to use pathogenic bacteria to reverse the results, achieving very good results. Then, this part is used to promote the rapid effect of the disease surgery. It can allow pathogenic bacteria to reproduce quickly and immediately reach the required number of pathogenic diseases."

Gret pulled the corner of his mouth and smiled hard:

"So...if the pathogenic bacteria cannot reproduce in this number, the disease surgery will fail?"

"Of course!" Master Hines nodded without thinking:

"Isn't the disease technique just used for this? You can't knock down the enemy immediately. What do you want to do with this spell?"

"I mean..." Grett gritted his teeth and tried to make suggestions:

"That's what I said, how can I use it to build immunity? For example, you use the modified epidemic technique... the fog of epidemic... to induce cowpox and vaccinate those indigenous people. Isn't it good to have it?"

"That must be cowpox. We have tried it with common pathogenic bacteria, but it's useless." Master Hines's research progress on the plague branch was obviously much more familiar than Gret:

"The part that determines the power of the disease technique seems to be the principle of controlling the reproduction of pathogenic bacteria. Too little reproduction will not work, and the patient will not get sick; if the reproduction is a little more reproduction, the patient will not fall ill immediately, but it may become ill within three to five days."

However, if you want to achieve the effect of "being immunized to this disease and not getting sick for a period of time"?

More than one magician from the Plague Branch rushed up bravely and retreated in a dilemma...

"So, can't this magic control the weakening of the pathogenic bacteria itself?"

"No." Master Hines shook his head firmly. Then, he came to his senses and gave Gret a very strange look:

"Why should I use this magic to control it? I remember that the priest of God of Nature can control the growth of bacteria? It seems that you produce penicillin or something, just use it to control it - by the way, have you isolated the pathogenic bacteria of yellow fever?"

"I, I've arranged for someone to filter the serum...wait for their progress..."

Gret fled in panic.

I also want to isolate the pathogenic bacteria of yellow fever, but the problem is, can't it be separated? That thing is not a bacteria, it is a virus! It is a virus!

My current ability is already able to lock in certain pathogenic bacteria and kill them in a directional manner; or slightly control Penicillium and Streptomyces to let them grow in the way I need it. But, control the virus?

Say to those viruses, "I'll give you energy, you'll become weaker, and you'll be weaker"?

It’s okay if the virus doesn’t have that brain!

Just like people who keep dogs and cats, they can train cats and dogs to do many specific movements, and even train strong working dogs. But, do you ask him to train a fish, an octopus, or a peach jellyfish to see?

Sorry, lower-class animals really don’t have that brain. Not to mention fish, even if you have a snake, the probability of being bitten is still very high.

Grett already feels that he is really strong when he can communicate with Penicillium. Grett really feels that he can't communicate with something that is less than 100 nanometers or even less than 50 nanometers.

So what should I do... From which direction can I take a detour to control these viruses and walk on the road of [attenuation] safely?

Is there any description of this in the memory of the diseased girl?
