The system invites me to be a teacher

"Xianglin, is this really the cow before your house?"

Villagers were once again surrounded by Sun Xianglin's cattle pen.

I can't blame everyone for asking, but the cow in front of me is really different from the original.

Smooth hair, a pair of huge bull eyes piercing, the most special is the pair of horns on the top of the head.

From the original light yellow to pitch black like ink, the cold shimmering, like a pair of peerless soldiers.

However, no matter how amazing the changes of this cow are, the villagers dare not approach it.

This is a cow with bovine schistosomiasis, in case you get infected...

Everyone shuddered at the thought of the blood-sucking worms in the ox blood released by Confucius and Mencius.

But one person is not afraid of it at all.

Sun Xianglin slowly walked to the side of the cattle, his rough big hand gently stroked the back of the cow, as if touching his lover whom he had crushed for many years.

"Of course this is the big black end of our house. You can see the scar on its hind leg if you don't believe it.

This was when it slipped while pulling the cart and was accidentally scratched by sharp rocks next to it.

For this it rested for a full half a month..."

Sure enough, when he heard Sun Xianglin's words, the villagers suddenly said, "This is really your cow? Is it really sick?"

Having said that, everyone instantly cheered up.

If Sun Xianglin's cattle can really get rid of bovine schistosomiasis, then his own cattle can definitely too.

Who knows Sun Xianglin shook his head: "Okay? How can it be so easy.

I took some blood last night, and conducted experiments according to the method of Teacher Kong, and found that there are still blood-sucking worms in the blood of cattle."

The villagers who had already walked a few steps forward, ready to see the cow, hurriedly backed away again.

"Xianglin, since the cow is not well, you should get out of the cowshed quickly, in case you get infected..."

"Yes, at this time, it's best to keep a safe distance from the cow.

It's not that we are afraid of death, but the most important thing is to have no life. If the cow is dead, you can feed it again, but if there is no human, then there is nothing."

"..."

Sun Xianglin felt helpless after hearing the discussion.

But he still let himself know everything he said: "Don't worry, everyone, although the blood-sucking worms in this cow's blood are not dead, they are much less than before.

And although the remaining blood-sucking worms are alive, they have lost their ability to reproduce."

Hearing Sun Xianglin's words, the villagers were instantly stunned.

"Lost reproductive capacity, is it true?"

"Yeah, you can't read it wrong, right? Those bugs are so small, how do you know they can't reproduce?"

"..."

Sun Xianglin did not defend himself, but got up and went to the kitchen.

After 5 minutes, he took out a needle tube and a porcelain basin.

"If there is anything wrong, you will see for yourself in a while."

Speaking, Sun Xianglin was extremely skilled at inserting the needle into the cow's body, and quickly drew out most of the cow's blood.

Pour the cow blood into the basin, pour in the salt, and then keep stirring.

This is exactly the method used by Confucius and Mencius.

When salt enters the blood of cattle, the concentration of salt in the serum will increase, causing the blood cells of the cattle to burst.

In this way, the red blood cell wall will settle and be completely separated from the serum, and the red blood-sucking worm can be seen.

You have seen Confucius and Mencius doing this experiment 5 days ago, and now you still can’t help but be frightened.

But soon people were surprised.

Because everyone found that compared with 5 days ago, the number of blood-sucking worms in these cattle blood was significantly reduced.

Moreover, every blood-sucking worm is soft and sluggish, a look of weakness, completely different from the alive and kicking five days ago.

Sun Xianglin explained next to him: "You may not know that after our farm cow drank a prescription provided by Teacher Kong, I would draw blood every two hours, and then observe the blood-sucking insects in the blood."

Upon hearing Sun Xianglin's words, the villagers couldn't help sweating profusely.

The blood is drawn once every two hours for 5 days. You clearly want to kill your cattle.

However, this thought only lasted for a moment, and was distracted by Sun Xianglin's next words.

"After taking the medicine provided by Teacher Kong, the number of these blood-sucking worms began to decrease and their vitality decreased.

But this is nothing for the prevention and treatment of schistosomiasis.

Because there are many ways to kill some blood-sucking worms, as long as the corresponding medicine can do it.

When the number of blood-sucking worms is reduced to a certain level, the efficacy of these drugs will begin to decrease until they disappear.

Once the drug is stopped, these blood-sucking worms will quickly reappear.

Just when I thought it was necessary to observe the effects of this medicine for a long time, I suddenly discovered a special phenomenon.

The most terrifying thing about the blood sucking worm is its reproductive speed, even if it has been removed from the blood and added a lot of salt that affects its physiological activity.

These blood-sucking worms will still gather together and continue to mate.

But over time, the frequency and willingness of these blood-sucking worms to mate began to decrease.

But yesterday, these blood-sucking worms were completely separated, as if they no longer had sexual interest in the same kind."

After listening to Sun Xianglin's words, the villagers' eyes lit up.

It seems to be so!

This situation can be observed with the naked eye, but it is basically difficult to detect if you are not paying attention.

Now that Sun Xianglin said it was broken, he immediately lost the secret.

"Xianglin, according to your words, doesn't it mean that this cow's bovine schistosomiasis has been completely cured?

But why does Teacher Kong have to wait until three months later?"

Sun Xianglin asked the speaker: "Do you know the life span of an adult pure blood sucking?"

The man shook his head, and Sun Xianglin said, "Three months!"

"Although the blood-sucking worms have lost their ability to reproduce, under the suppression of drugs, their physiological activity has also been greatly reduced.

But no matter what, these blood-sucking worms still have the blood-sucking function in the cow.

In other words, as long as these blood-sucking insects do not die for a day, they will affect the health of the cattle to a certain extent."

Listening to Sun Xianglin talking freely, the villagers looked at each other.

Although what this guy said is quite reasonable, everything is his speculation, and the truth is still unverifiable.

But everyone's looks are still much better than before.

Whether Sun Xianglin's words were true or false, everyone saw the hope of curing bovine schistosomiasis.

Suddenly someone said: "No, Xianglin, there is a problem with your inference."

Sun Xianglin was taken aback: "There is a problem, what is the problem?"

He is very confident in his inferences, and there is no flaw from logic to reasoning.

The person continued: "You said that although these blood-sucking worms have lost their ability to reproduce, they will continue to suck the blood of the cow's body, causing its body to remain in a state of continuous weakness.

But I look at your cattle, but they don’t look weak at all."

When other people heard him, they nodded in agreement.

The villagers knew what Sun Xianglin's cattle was like before and what they are now.

Regardless of body or spirit, it is more than a little bit better than before?

"This one……"

Sun Xianglin frowned, this was the only thing he didn't understand.

Because according to my own theory, although my own cow will get rid of sickness to a certain extent, it still has a certain gap with normal healthy cows.

You can see his physical characteristics, especially the pair of horns on the top of his head. If others say that his cow has evolved, he will believe it.

This is another person who said: "Judging whether a cow is healthy or not, the conclusions drawn from the appearance are not necessarily accurate.

It depends on the farm work it can do.

Xianglin, why don't you pull this cow into the ground to see how its physical strength and endurance are?"

Sun Xianglin's eyes lit up, this is a good way.

He said that he took the cow out of the cowshed, and then pulled out an iron plow from another storage room.

The villagers immediately understood what he meant, and at that time two young guys came out and expressed their willingness to help.

Sun Xianglin pointed to the back of his yard and said, "Everyone, for the convenience of testing, I will pull the cow over the soil for a while, so you can watch from behind."

Everyone took a breath after hearing what he said.

Because the place Sun Xianglin was referring to was a rocky land.

This kind of land is very difficult to cultivate because of the heavy stone.

In addition, the land is barren and hardly produces any crops, so it has been abandoned.

However, this kind of terrain is just right to detect the physical condition of the cow, and at least it can save a lot of time.

Soon, the ox was pulled to the side of the land by Sun Xianglin, and the plow was set up.

Sun Xianglin yelled, flicked the whip in his hand, and saw the cow in front of him suddenly exert force.

A shocking scene happened.

The originally hard ground was plowed easily under the force of this cow.

How is this possible?

To know that terrain like this, even the strongest bull, trying to plow a short distance, will have to exhaust his strength.

But the cow in front of...

Are you still a cow?

The tractor is not as strong as you, okay!

In half an hour, the land in front of him was ploughed seven or eight.

Finally, Sun Xianglin stopped with his cow.

"Xianglin, how do you feel?"

Sun Xianglin thought for a while and said, "I don't know why the power of this bull has increased much more than before.

However, it is only the increase in strength, and there is still a certain gap between physical strength and normal cattle."

Everyone frowned again.

Strength increases, but physical strength decreases. What is the situation?

Just when everyone couldn't understand, a voice suddenly said:

"If you can't guess it, why do you guess? If you want to know the answer, just go to Teacher Kong and ask if it's OK."

The villagers' eyes lit up, indeed!

Both the diagnosis of bovine schistosomiasis and the provision of prescriptions were done by Confucius and Mencius alone.

So if you want to understand the current situation of this cow, asking Confucius and Mencius is the best choice.

"By the way, Mr. Kong, it's noon now, why haven't you seen his shadow yet?"

As soon as these words came out, countless eyes were cast. Confucius and Mencius were teachers, so naturally they were in school.

At this point, everyone turned and walked towards the school.

Confucius and Mencius are giving lectures to the students in front of them, and they are still raising livestock.

But this time he is not talking about cows, but chickens.

"There are two common ways to raise chickens, one is free-range raising, and the other is gathering raising.

Hearing this, some people will definitely say that chickens raised in free-range must taste better than chickens raised in groups.

I do not deny here.

The free-range chicken is delicious and nutritious, and it is a rare good product in meat.

Some people even gave the chickens raised in this way a name: free-range chickens.

However, the weakness of this chicken is also very obvious.

It has a long growth cycle, slow weight gain, and easy loss.

In contrast, chickens raised in clusters do not have these problems.

According to the situation in our Yunxi Village, I personally admire the chickens raised by gatherings.

This kind of broiler can be sold in only three months, and the chicken is fat and meaty, even if it is sold cheaper, it will make more money than if it goes down.

However, this kind of collective chicken raising is very easy to get sick. If there is no scientific thinking method, only a small bird flu can be used to waste all your efforts for a month or two.

Now let me tell you a few precautions for collective chicken raising: "..."

Confucius and Mencius talked endlessly on the podium, and the students in the audience listened very seriously.

Since Confucius and Mencius showed the bovine schistosomiasis to everyone on the spot last time, the enthusiasm of these students in learning has risen to a step.

Especially for this kind of learning of common sense of life, many people already have a foreboding that if they don't go to high school and university, then they will probably be able to use what Teacher Kong said in the future.

Based on this alone, Teacher Kong is much better than the young people who came to support teaching before.

At least he thought so.

Just as he was about to enumerate the summary of chicken raising for everyone, there was a commotion outside the school.

Confucius and Mencius frowned, what happened?

He was about to walk out of the classroom to ask about the specific situation, but he was blocked by a group of people as soon as he got off the stage.

"Teacher Kong, after Sun Xianglin's cows have taken the medicine you gave, can they kill all the blood-sucking worms?"

"Yes, I also heard Sun Xianglin say that your medicine can inhibit the reproduction of blood-sucking worms in the blood of bovine schistosomiasis. I wonder if it is true?"

"..."

Confucius and Mencius couldn't help but breathe a sigh of relief when these people asked.

He smiled and said: "Don't worry, folks and fathers, the most important function of the anthelmintic I formulated with Chinese medicine is the reproduction of a schistosomiasis.

Everyone knows that the most important reason why blood-sucking bugs are so harmful is that they reproduce extremely fast.

Only by completely suppressing its reproductive speed can the diseased cattle be completely cured.

So when you treat your own cattle, you must strictly follow the formula I gave you.

Once something goes wrong, all your previous efforts will be lost.

..."

These people only listened to the first few sentences of Confucius and Mencius. As for what was behind, no one paid any more attention.

Because everyone was surprised to find that Sun Xianglin's previous speculations were all true.

This is simply too fantasy.

However, some people couldn't help asking: "Mr. Kong, if you say, the most important sign of your medicine is to inhibit the reproduction of blood-sucking worms.

But even if you succeed, the bodies of those cows should not be as good as before.

But the Sun Xianglin family's farming power is even greater than before. What is going on?"

Hearing this, Confucius and Mencius smiled softly:

"That's it. In order to restore the health of these cattle as soon as possible, three of the five herbs I gave are to stimulate their physical development and improve their resistance.

So what you see about the cow is that its power has increased, but its endurance is still not as good as before.

Therefore, when treating such cows, let them work as long as possible.

Otherwise, it will damage its health to a certain extent."
