Siheyuan: I stand for Xu Damao because he is my brother

Xu Dacan was suddenly shot by the dusty memories again, just like pouring a bowl of vinegar into mutton soup with steamed buns, stirring it vigorously, and then eating it all in one breath, so sour and refreshing!

When Xu Dacan came to his senses from his memories, he looked at the anxious girls and said, "Don't panic, she doesn't have epilepsy, she's poisoned."

With a plop, Xu Dacan turned around and found that Cheng Fei was kneeling on the ground.

Then the other girls in their dormitory were also shocked. You looked at me, I looked at her, and I guessed that we were all acting out 70 episodes of The Legend of Zhen Huan in our hearts, desperately guessing who poisoned Jiang Ling? And what kind of poison was it!

Xu Dacan was almost amused by them. He pulled Jiang Ling up from the ground in a funny way and explained to them: "No one poisoned her. It's typical that she poisoned herself with anger. Have you heard of hyperventilation syndrome?"

The girls all shook their heads.

Xu Dacan thought to himself that it was right that he had never heard of it. He had only heard of this disease in the 21st century.

At that time, he was teaching boxing in a club. Two male coaches started arguing over a rich woman. One of them couldn't win the argument and poisoned himself with anger.

The symptoms were exactly the same as Jiang Ling's. Xu Dacan and his team initially sent the patient to the community hospital, but the community hospital asked him to do a computer image and CT scan.

Xu Dacan and the others felt that it was unreliable. Human life was at stake. He was in such a state, why didn’t they rescue him quickly?

After everyone discussed it, they decided to go to a top three hospital! Just like that, Xu Dacan and his group relied on their muscular bodies and their strength to carry him out of the community hospital.

A top-level hospital is a top-level hospital! I went to the emergency room and explained the situation to the hospital staff. A random young doctor came in, took a look and said with a smile: "He poisoned himself with anger."

"..."

The treatment method is also extremely simple.

Xu Dacan asked a few girls: "Do you have anything made of pure cotton?"

He originally wanted to say "the best mask", but before he could finish, Cheng Fei stuffed something into his hand.

Um, it's made of pure cotton, symmetrical on both sides, with two straps, and the hooks on the back are so complicated that they seem to have a code, and a second-rate person like Xiao Jizi definitely can't untie them...

When Cheng Fei came to her senses, she handed over something in a hurry, and her face suddenly turned as red as a monkey's butt.

As for Xu Dacan, he had already taken the things. If he asked Cheng Fei to exchange them at this time, it would be a complete lack of consideration for the girl's dignity.

Xu Dacan simply put the thing on Jiang Ling's face and said to her: "Listen to me, inhale, exhale."

"Yes, relax and don't exhale too deeply, that's it, very good."

Probably only a few minutes passed, and just when everyone was feeling uneasy, Jiang Ling suddenly reached out and grabbed Xu Dacan's arm.

Then he sat up, Xu Dacan quickly let go, Jiang Ling was so angry that he tore off the "mask" on his face and yelled: "Cheng Fei, you idiot! Cover my face with this!"

Xu Dacan was happy. This girl named Jiang Ling was actually a Sichuan-Chongqing Tyrannosaurus. The familiar feeling came back to him.

The girls were all stunned, thinking they were hallucinating.

Then, Cheng Fei rushed over with a roar, and without thinking twice, she hugged Jiang Ling in her arms, hugged him tightly, and cried bitterly: "Wow, Jiang Ling, you scared me to death, I will never quarrel with you again..."

She started crying, and was taken aside by the other two girls: "Raincoat, you didn't even take off your raincoat."

Cheng Fei took a closer look and found that Jiang Ling's bed and quilt were all wet with rain.

"..."

Cheng Fei's roommates were all amazed. Isn't this too miraculous? Jiang Ling suddenly got better, but how did she get better? Didn't the "teacher" take any effective measures?

Because of his age, Xu Dacan is often mistaken for a teacher by younger students, especially when he wears a green cotton military jacket with a maroon fur collar and holds a thermos cup in his hand, even faculty and staff are easily misunderstood.

One time he went to the cafeteria to get food. As soon as he lined up, the cafeteria director enthusiastically invited him to a small private room, and urged the waiter to ask the kitchen to cook a few dishes quickly!

And he insisted that Xu Dacan taste the fine wine he had collected for many years...

Xu Dacan was so scared that he ran away while he went to the toilet.

We’ve strayed off topic, let’s get back to Cheng Fei and her roommates’ dormitory.

One girl even secretly wondered in her heart, could it be that Cheng Fei's body could secrete some strange substance?

Even the Zhao Zhao she had worn could cure all poisons with just a sniff, so wouldn't she have to rub it more often in the future...

Seeing that his memories had not deceived him and his judgment was correct, Xu Dacan smiled with relief.

While dealing with the girls' chatter, he explained in a mature manner: "Young people, you must learn to control your emotions and not stay up late. This student had an irregular work and rest schedule, which led to excessive emotions. In addition, he had a quarrel with his roommate and his breathing rate was too fast. As a result, he lacked carbon dioxide in his body and caused respiratory alkalosis."

Alkalosis? Carbon dioxide deficiency?

Several girls looked at each other, and finally the bravest one raised her hand: "Teacher, doesn't carbon dioxide reduce the oxygen content and make it difficult for people to breathe?"

Well said. You can tell at a glance that you have studied chemistry well. But don’t say that again next time.

Looking at these girls whose faces were full of admiration, Xu Dacan could only show off his knowledge to these girls in order to maintain his image as a superior person.

"When we are emotionally excited, our breathing rate will increase, but when the rate is too fast, it will lead to excessive ventilation of carbon dioxide, which will cause a lack of carbon dioxide in the body, which is called respiratory alkalosis.

In addition, the symptoms look very similar to epilepsy when it occurs, such as stiff limbs and tremors. If you don’t have experience, it’s easy to mistake it for epilepsy.”

The last sentence can be considered as a relief for Cheng Fei.

Through his observations just now, Xu Dacan also realized that Cheng Fei didn't get along well with the other ladies in the dormitory.

Otherwise, she wouldn't have been allowed to run out alone to ask for help.

The girls in Cheng Fei's dormitory finally understood: "It turned out that Jiang Ling exhaled heavily, and as a result, all the carbon dioxide in his body was exhaled, causing poisoning..."

Anyway, this is how the girls explained it to the teacher when he finally showed up.

The teacher humbly asked Xu Dacan: "School doctor, does she need to be sent to the hospital for further treatment?"
