The system asked me to be a teacher

Chapter 284 The New Change of the Cow

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

Outside the cattle pen of Sun Xianglin's house, the villagers once again surrounded them.

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

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 light shone like a pair of peerless magic soldiers.

But no matter how miraculous the change of the cow is, the villagers dare not approach it.

This is a cow with bovine blood worm disease, in case he is infected...

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

But there was one person who wasn't afraid of it at all.

Sun Xianglin walked slowly to the side of the cow, and gently stroked the back of the cow with his rough hands, as if he was stroking a lover who had been in love for many years.

"Of course this is my Dahei, if you don't believe me you can look at the scar on its hind leg.

This is when it slipped its feet when pulling the cart and was accidentally scratched by the sharp stones next to it.

For this reason, it rested for half a month..."

Sure enough, upon hearing Sun Xianglin's words, all the villagers suddenly said, "Is this really your cow? Is it really cured?"

Having said that, everyone cheered up instantly.

If Sun Xianglin's cattle can really get rid of bovine hemorrhoids, then his own cattle will certainly be able to as well.

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

I took some blood last night and conducted an experiment according to Teacher Kong's method, and found that there were blood-sucking worms in the cow blood. "

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

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

"Yeah, during this time period, it's best to keep a certain safe distance from the cattle.

It's not that we are afraid of death, but the most important thing is that there is no life. If the cow is dead, it can be fed again, but if the people are gone, there will be nothing. "

"..."

Hearing everyone's discussion, Sun Xianglin was a little helpless.

However, he still told himself what he knew: "Don't worry, everyone, although the blood-sucking worms in this cow's blood are not dead, they are much less than before.

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

Hearing Sun Xianglin's words, all the villagers froze for a moment.

"I lost the ability to reproduce, is it true or not?"

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

"..."

Sun Xianglin didn't try to defend himself, but got up and went to the kitchen.

Five minutes later, he took out a needle and a porcelain basin.

"Whether there is anything wrong, you will see for yourself after a while."

Speaking of which, Sun Xianglin inserted the needle tube into the cow's body very skillfully, and quickly drew out more than half of the tube of cow's blood.

Pour the cow's blood into the basin, then 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, it will increase the concentration of salt in the serum, which will cause the blood cells of the cattle to rupture.

In this way, the cell wall of the red blood cells will settle and completely separate from the serum, and the red blood-sucking worms can be seen.

You have seen Confucius and Mencius do this experiment 5 days ago, and you still can't help but feel terrified when you look at it now.

But soon people were surprised.

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

Moreover, every blood-sucking worm is limp and weak, completely different from the lively and lively 5 days ago.

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

Hearing Sun Xianglin's words, all the villagers couldn't help sweating profusely.

Blood is drawn every two hours and lasts for 5 days. You obviously want to pump your cows to death.

However, this thought only lasted for a moment, and Sun Xianglin's next words diverted his attention.

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

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

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

When the number of blood-sucking worms decreases 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 effect of this medicine for a long time, I suddenly discovered a special phenomenon.

The most frightening thing about a blood-sucking worm is its reproduction speed, even if it has been extracted from the blood, and a large amount of salt is added to affect its physiological activity.

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

But over time, the blood-sucking worms began to mate less frequently and less willingly.

And until yesterday, these blood-sucking insects have completely separated, as if they no longer have any sexual interest in the same kind. "

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

It seems so!
This kind of situation can be observed with the naked eye, but it is basically difficult to find if you don't pay attention.

Now that Sun Xianglin tells the truth, the secret will be gone immediately.

"Xianglin, according to your words, doesn't it mean that the bovine bloodworm disease of this cow has been completely cured?

But why does Teacher Kong insist on us waiting until three months later? "

Sun Xianglin asked the speaker: "Do you know the lifespan of an adult vampire?"

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

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

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

In other words, as long as these blood-sucking worms survive for a day, they will affect the health of cattle to a certain extent. "

Listening to Sun Xianglin's eloquent talk, the villagers looked at each other in blank dismay.

Although what this guy said seemed to make sense, everything was his speculation, and it was still impossible to verify whether it was true or not.

But everyone looks much better than before.

Regardless of whether Sun Xianglin's words were true or false, everyone saw the hope of curing bovine bloodworm disease.

Suddenly someone said: "No, Xianglin, there is something wrong with your deduction."

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

He is very confident in his deduction, and there are no flaws in logic and reasoning.

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

But I can see that your cattle don't look weak at all. "

When the others heard what he said, they immediately nodded in agreement.

The villagers know what Sun Xianglin's cattle were like before and what they are like now.

Whether physically or mentally, how much 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 cow will get rid of the sickness to a certain extent, there is still a certain gap between it and a normal healthy cow.

Judging by its physical characteristics, especially the pair of horns on the top of its head, if others say that his cow has evolved, he will believe it.

This is another person who said: "To judge whether a cow is healthy or not, it is not necessarily accurate to judge from the appearance alone.

It also depends on whether it can do farm work.

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

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

As he spoke, he led the cattle out of the cowshed, and then pulled out an iron plow in another utility room.

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

Sun Xianglin pointed to the back of his yard and said, "Everyone, for the convenience of inspection, I will pull the cow to dig the soil later, and you can just watch from the back."

After hearing his words, everyone gasped.

Because the place Sun Xianglin pointed to was a rocky field.

Because of the heavy rocks in this kind of land, it will be very difficult to cultivate.

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

However, this kind of terrain is just right for detecting the physical condition of cattle, at least it can save a lot of time.

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

Sun Xianglin yelled and flicked the whip in his hand, only to see the bull in front of him suddenly exert strength.

A shocking scene happened.

The originally hard ground was easily plowed by the ox.

How can this be?

You know that in terrain like this, even the strongest bull will have to exhaust his energy to plow a short distance.

But the cow in front of me...

Are you still a cow?

A tractor doesn't even have your strength, okay?

Half an hour passed quickly, and the land in front of me was plowed in sevens and eighties.

Finally Sun Xianglin stopped with his cattle.

"Xianglin, how do you feel?"

Sun Xianglin thought for a while and said: "For some reason, the strength of this cow has increased a lot compared to before.

But it's just an increase in strength, and there is still a certain gap between physical strength and normal cattle. "

Everyone frowned again.

Strength increases, but stamina decreases. What's going on?
Just when everyone couldn't figure it out, a voice suddenly said:

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

All the villagers' eyes lit up, indeed!

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

So if you want to understand the current condition of the cow, it is the best choice to ask Confucius and Mencius.

"By the way, what about Teacher Kong, it's already noon now, why haven't you seen his shadow yet?"

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

Having said that, everyone turned around 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 and the other is group breeding.

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

I don't deny it here.

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 is easy to get lost.

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

According to the situation in our Yunxi Village, I personally prefer the chickens raised together.

It only takes three months for this kind of broiler chicken to be ready for slaughter, and the chicken is thick in fat and meat. Even if it is sold at a lower price, it will still make more money than if it is sold at a lower price.

However, the chickens raised in this kind of aggregation are very easy to get sick. If there is no scientific way of thinking, it only takes a small bird flu to make all your efforts for a month or two in vain.

Now let me tell you a few things to pay attention to when raising chickens in agglomeration: "..."

Confucius and Mencius were eloquent on the podium, and all the students in the audience listened very carefully.

Since Confucius and Mencius showed bovine hemosomiasis to everyone last time, the enthusiasm of these students in learning has instantly increased to a higher level.

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

Based on this alone, Teacher Kong is much better than those young people who came over to teach.

At least he thinks so.

Just when he was about to give everyone an overview of raising chickens one by one, there was a sudden commotion outside the school.

Kong Meng frowned, what happened?
He was about to walk out of the classroom to ask about the specific situation, but he was firmly blocked by a group of people as soon as he got off the podium.

"Mr. Kong, can Sun Xianglin's cattle kill all the blood-sucking worms after taking the medicine you gave?"

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

"..."

Hearing what these people asked was this, Confucius said with a smile: "Don't worry, everyone, the anthelmintic medicine I formulated with traditional Chinese medicine is mainly used to inhibit the reproduction of blood-sucking worms.

Presumably everyone knows that the most important reason why blood-sucking worms are so harmful is that they reproduce very fast.

Only by completely suppressing its reproduction speed can it be possible to completely cure the sick cow.

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

Otherwise, once something goes wrong, all the previous efforts will be wasted.

......"

The villagers only listened to the first few sentences of Confucius and Mencius's words, and no one paid any attention to what was behind them.

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

Finding a few medicinal materials at random can inhibit the reproduction of blood-sucking worms, which is simply too unreal.

However, someone still couldn't help asking: "Mr. Kong, according to what you said, the medicine you prepared is mainly to inhibit the reproduction of blood-sucking worms.

But even if it succeeds, the bodies of those cows should be much worse than before.

But Sun Xianglin's cattle are stronger than before, so what's going on? "

Hearing this, Confucius and Mencius said:

"That's right, the farm cattle that have been replaced by bovine hemorrhoids are generally weak because of the long-term pain.

In order to restore these cows to health as soon as possible, one of the five herbs I gave stimulates physical growth and improves their resistance.

The situation of the cow you see is only that its strength has increased, but its endurance is still not as good as before.

Therefore, for such a cow, try not to let it work for too long.

Failure to do so will cause irreparable damage to its health. "
