Masha glanced at his sister.

Ma Xiaomei has already developed an interest in chemical biology, and experimenting to further stimulate her curiosity may allow her to learn enough knowledge in the process of "playing" to be promoted.

Although Ma Sha's understanding of biology and chemistry is limited to the scope of the syllabus of the college entrance examination, and he will not understand it if he has more, this knowledge may be able to promote the little girl to the master's level.

A master from another world, with low gold content.

Marsha pondered, and the little girl licked her hand vigorously.

"It's not bitter." She looked at Ma Sha blankly, "All healing potions are bitter, my sweat is not bitter." ”

"Because it's not a cure, it's an antibiotic."

As Masha answered, he muttered in his heart, is the healing medicine of this world bitter...... So is this what this world's "good medicine is good for the sick"?

The little girl licked it again, then stared at her palm, "I can't see the bacteria on my hands." ”

"Nonsense, you're a broad-spectrum antibiotic."

"Isn't this a bacterium?"

"Fighting bacteria with germs? Maybe, but this one isn't. Now you have a cold germ that isn't afraid of hot water, and if it works quickly, it might be able to be used in battle......"

As soon as Masha finished speaking, the little girl sighed: "It's useless, even if the hot water can't die, people know that there are enemies of the Pasteur school, and they will directly transform into fire elements, and bacteria and other things will inevitably die." ”

Masha staggered.

- There is one thing to say, indeed.

Pasteur's school is really weak enough, and a single transformation of the fire element can restrain the entire school to death.

If there is such a profession in the game that is completely killed by a single magic, the player will riot.

- Hey, wait, how do I remember that there was such a thing? For example, what kind of legend is there, it seems that there is a card that makes all professions except druids miserable?

Oops, I haven't played that game, I don't know the details.

Masha retracted her thoughts, thinking of ways to strengthen the little girl as much as possible.

As long as the existence of the Pasteurist school is not exposed, it may be possible to quietly infect the opponent and weaken the opponent's power.

But there's a problem, if the bacteria are too effective, people may react all at once. Therefore, it is necessary to develop bacteria that are not obvious and quietly affect the enemy......

However, such bacteria could not immediately stop the enemy's actions, what if the enemy killed the Pasteurists who hid their identities as ordinary people?

- The bacteria are powerful and will be recognized in seconds and then transformed into the fire element to dispel, and the bacteria are weak and it is difficult to stop the enemy.

- It seems that the Pasteurists want to protect themselves, so they can only take the route of maniacs.

At this time, the little girl suddenly said: "Second brother, you said that if I make something so weak that others can't feel it very much, and when I feel the bacteria that are already terminally ill, with the second brother's mouth cannon ability, and the watch given by Captain Nemo, will it be outstanding?" ”

"Yes, but why not cause an explosion directly at the enemy's feet?" Masha asked rhetorically.

The little girl patted her head: "Yes." Just blow it up and it's over. That feels like I'm still more promising...... Although it's not necessarily fried, the thought of being able to paste the opposite face feels a little cool. ”

Masha suddenly had an idea.

"Wait a minute, can we use a layer of sugar coating, keep your methane bacteria, let the enemy eat it, and then the sugar coating will melt in the stomach...... Then, no, stomach acid kills most bacteria......"

"What is stomach acid?"

"A biological acid secreted by the glands of the stomach that helps the stomach grind food, and most of the bacteria are killed by saliva and stomach acid......

"What is saliva?" The little girl turned into a "little question mark" and asked questions continuously.

Grandpa Ma Sha replied like a stream: "Saliva is saliva, although you can't feel it, but this is actually a very powerful bactericide." ”

If Masha fell when he was a child, his father would definitely say, "It's okay to apply some saliva yourself", and it was a long time before Masha knew that there was a scientific basis for this, but the saliva sterilization was not thorough, so even if the saliva was applied, the wound would still be infected and suppurated.

However, there is a scientific basis for this, at least partially.

"That's it, so my sweat is actually a strengthened version of stomach acid and saliva?"

Masha listened to the little girl's words, and suddenly imagined the little girl covered in saliva - oh, it's too dirty, I respect myself.

"No, you're an antibiotic, or a fast-acting version, it's much stronger than saliva."

"Oh. However, second brother, you just said that method, I think you can give it a try, you see, since my bacteria are thrown into hot water, there will be bacteria that can tolerate hot water, so maybe if I throw it into stomach acid, there will also be stomach acid-resistant things? ”

Marsha: "Theoretically, all living things will evolve in the direction of adapting to the environment, but this evolution is generally in tens of thousands of years, tens of thousands of generations......

Masha fell silent suddenly.

He remembered one thing, bacteria and viruses change quickly, and one of the main reasons is that they iterate quickly.

He remembered a science fiction novel that used artificially increasing the speed of iteration to develop anti-AIDS drugs.

It seems that some kind of machine is used, and the HIV virus has multiplied for hundreds of thousands of generations inside the machine, and the human immune cells have also been updated for hundreds of thousands of generations, and finally the evolved cells are taken out and implanted into the human body to form an overwhelming immunity to the current AIDS.

It seems that this is the case, and it seems that it was written by a Chinese science fiction writer. Of course, as a science fiction novel, it must show the hidden worries of scientific and technological development in the end, and those "critics" who don't do it will dislike the lack of depth, so at the end of the novel, human beings seem to have gotten away?

MASHA COULDN'T REMEMBER CLEARLY, BUT HE GOT THE IDEA.

"Listen, let's get a little stomach acid first, and then you keep throwing bacteria into the stomach acid to die, as long as the bacteria die enough, there will always be acid-resistant bacteria."

- It's just that no one knows how many bacteria will have to die for this mutation to appear.

The little girl didn't think deeply, she asked suspiciously, "Okay, then where are we going to get stomach acid?" ”

Masha pointed to the little girl's belly.

"Can't you release germs into your own stomach?"

"Oh, that makes sense."

The little girl began to sprinkle something on the biscuit snack in front of her, and then ate the biscuit in one gulp.

"Wait, how do I know when I've developed bacteria that are resistant to stomach acid?"

"Simple, this bacterium will break down the contents of your stomach to produce methane, and the methane gas will be spit out down the esophagus, right, you can try to see if you can breathe fire, and you will know if there are any bacteria that survive?"

"Oh, that makes sense!" The little girl clapped her hands, and then she reacted to Ma Sha's bad idea, she glared at Ma Sha and shouted, "Second brother! ”

"Spitfire is handsome." Masha was very calm.

"What if I blow up?"

"Rest assured, as long as you don't swallow oxygen-producing bacteria, and you spray methane before igniting it, spewing out all the remaining air in your esophagus, and the combustion will only happen inside your mouth after ignition."

"Then my mouth will be burned!"

"yes, so I'm kidding. Tsk, this method doesn't work, you have to get stomach acid, I want to think about the chemical formula of stomach acid, how can I make it artificially......"

Masha suddenly patted his head: ", I'm stupid X." ”

The little girl looked at him: "Are you enlightened?" ”

"The key is not which acid, but the pH value, and the sterilization of gastric acid is actually achieved through an acidic environment. As long as you mimic the concentration of gastric acid in the stomach and configure a solution with a similar pH value, you can do it. ”

The little girl was completely confused, looking at Marsha, and suddenly she touched her head: "I have a little headache, so these are not the knowledge of my school?" ”

She already has experience.

The little girl hesitated, but then asked, "What is PH?" What is an acidic environment? ”

Masha turned her head to look at her, and as soon as she opened her mouth to explain, the little girl shrank her neck—she was indeed experienced.

Masha said slowly in a gentle voice: "PH is ......"

A few seconds later, the little girl rolled on the ground with her head in her hands.

It seems that it is useless to make the voice gentle.

- Obviously, when I mentioned acid and alkali, she didn't have anything to do, but as soon as she explained the specific knowledge, she was tricked.

- The reason of the world is really stingy.

**

Half an hour later, the little girl finally returned to normal.

"This time it's much more fierce than before," she said, "I can't bear it anymore, second brother, be gentle!" ”

"You are making this statement, fortunately there is no one else on the ship, otherwise your second brother would have died socially."

The little girl pouted and did not speak.

Whoever is tortured to roll on the ground is not in a good mood.

"To prepare an acid solution similar to stomach acid, I first have to measure the acidity and alkalinity of stomach acid."

WHY, MASHA FORGOT WHAT THE PH OF STOMACH ACID IS. And this is another world, maybe the stomach acid of people in another world will be stronger.

While recalling the process required for the experiment to measure acidity and alkalinity, Masha wrote down what was needed on a piece of paper.

"Get that done, and then we can get to work."

The little girl took the note from Marsha's hand, looked at the long list, and stuck out her tongue.

"That's a lot, I feel like it's too easy to be discovered if you take it all from the potions lab at home. Otherwise, they should ask for Jiangcheng Road, they seem to want to please Captain Nemo too. ”

After the little girl finished speaking, she suddenly hiccuped loudly.

Masha deliberately looked at the little girl with strange eyes, trying to tease her.

Before he could speak, the little girl hiccuped again.

Then she started hiccups continuously.

"Huh? Strange, second brother, I feel like my stomach is bloating! ”

Marsha frowned.

- Wouldn't it?

He unleashed a small ignition spell.

A bright flame instantly illuminates the room.

Masha sat on the ground, his hair was scorched, but fortunately it didn't burn.

The little girl threw her head back, her mouth spewing fire, and she ran quickly to the sink in the room, and plunged her head into it.

Then Masha saw the water in the sink bubbling with large bubbles.

"Wait a minute! Hurry up and lick the sweat off your hands! ”

The little girl pulled her head out of the sink and licked her hands like a blind bear.

Looking at the little girl who gradually calmed down, Masha was speechless.

- Is this a direct acquisition of acid resistance by bacteria? So fast?
