Ask Sword

I see.

Li Ang raised his head and forced a smile, Where's your teacher Qiu?

She's gone to sleep.

Then you should go to rest too. Everyone is very tired during this time. I'll be in charge here.

Li Ang patted his apprentice on the shoulder, and told the girl to go back to the temporary dormitory upstairs, while he himself walked out of the room holding hot tea.

The autumn wind is bleak, and the fallen leaves are flying. There were no common people to be seen on the street, only soldiers and government servants wearing masks and armbands of various colors were delivering meat, food, and today's disease bulletins from door to door.

The air was filled with a strong and choking sulfur smell. Although it was unpleasant, it was better than the horrible stench that hung over the city some time ago.

Come on?

A rough voice sounded from the side, and Li Ang turned his head to look, only to see Yan Yundang wearing armor and holding a horse spear, standing at the door like an ordinary old soldier, holding a horn wine bag in his left hand.

No.

Li Ang shook his head, I just drank tea.

You are the most unlike Yu Guo people I have ever seen.

Yan Yundang shook his head, opened the wine bag with one hand, and took a big gulp of strong liquor, I don't drink at all, not like a school disciple, but like an ascetic monk.

I prefer to stay awake.

Li Ang smiled slightly, perhaps because of his inertia as a surgeon in another world, he almost never drank alcohol, even when he attended Song Shaoyuan's wedding last time as best man, he only drank a few cups.

Although I don't drink alcohol, I actually have a good capacity for alcohol. The doctor disinfects the palms with alcohol every day. The alcohol absorbed by the skin directly enters the liver. In order to eliminate ethanol, the liver will continuously increase the enzyme (alcohol dehydrogenase) and increase the alcohol capacity in disguise.

You kid will say things that ordinary people can't understand.

If you don't drink, life will be much less fun.

After drinking strong alcohol, Yan Yundang smacked his lips, squinted his eyes and said, The people of Yu State are too bitter. Before the invention of Lingqi locomotive, before the invention of allicin and penicillin, every farewell may be a farewell.

I can't express my emotions, I can only drink alcohol.

That's why there are farewell wine, reunion wine, out of the pavilion wine, and Zhuang Xing wine

He paused, and said calmly: In the autumn of the second year of Tianshou, the Turkic army invaded the border and invaded the border of our country of Yu. I left my pregnant wife, went out with the army, and stationed in Luanshi City.

The Turkic cavalry cut across the northern border, and the cities fell one by one, and Luanshi City was also reduced to an isolated city.

The siege lasted for five months. The arrows and food ran out, and the comrades around us fell one by one. We had to stand at the top of the city and throw stones at the enemies who tried to climb the wall to protect the only remaining Nian Shi.

The lieutenant general who scolded the Turkic barbarians with you during the day died quietly after a night because of blood carbuncle or other diseases.

Without the general, deputy general, and captain, the last 300 comrades in the city gathered together to discuss for a while, and finally 20 people including me were selected, and they rode around to the rear of the Turkic army in the dark of night. Burn their food supplies.

The plan was successful, and the flames ignited by the grain and grass soared into the sky,

The scolding of Turkic words, the sound of horseshoes, and the sound of chanting devices piercing the sky entered my ears.

The arrows enveloped like a scattered rainstorm.

A team of 20 people rushed to the enemy line, and in the end I was the only one who escaped back.

In the early morning of the next day, the Turkic army finally retreated. And the scouts in the rear also sent letters from my hometown - my wife had a normal delivery, and the mother and child are safe.

That day was the best drink I've ever had.

Looking at the silent city in front of him, which had witnessed too many life and death during this period, he turned his head to the silent Li Ang and said calmly: Heaven reincarnates, life and death are as usual.

Don't be too hard on yourself.

Um.

Li Ang nodded, realized belatedly, and said with a smile, Besides the doorman, why do you also work part-time as a psychotherapist now?

Also why don't you wear a mask?

Be kind as the liver and lungs of a donkey.

Yan Yundang rolled his eyes, but still honestly took out the mask from his arms and put it on his face, I am a master of martial arts, how can I get sick so easily.

That's what you said before you got anemia, didn't you?

Li Ang unceremoniously exposed Yan Yundang's big words, and said seriously: The plague is unusual, we must pay more attention to it.

I know, I know.

Yan Yundang waved his palm impatiently, I'm here to guard the door, you go back to sleep.

After cured of anemia, Yan Yundang was still one of the strongest martial arts masters in the world. With him as the guard, Li Ang could indeed sleep peacefully.

Still, he couldn't sleep.

To curb the plague, it is not enough to rely solely on isolation measures to cut off the chain of human-to-human transmission.

It is necessary to produce a special medicine that can treat the plague as soon as possible, so as to reduce the death toll as soon as possible, and to pull the plague from the position of terminal illness that is difficult to cure.

Li Ang dragged himself to the basement, flipped the button on the wall, and turned on the talisman lamp.

When the lights came on, the basement was full of experimental instruments such as test tubes, flasks, and centrifuges, and all kinds of data were densely written on the blackboard.

Drugs against plague include aminoglycosides, fluoroquinolones, third-generation cephalosporins, tetracyclines, gentamicin, kanamycin, amikacin, and so on.

But for the three plague diseases, the most effective and most effective is still streptomycin.

It is an antibiotic extracted from the culture medium of Streptomyces griseus, which can act on the ribosomes in the bacteria, inhibit the synthesis of bacterial proteins, destroy the integrity of the bacterial cell membrane, and then kill the bacteria.

Streptomyces are mainly distributed in the soil, and there are thousands of species. It is necessary to find suitable Streptomyces, cultivate, isolate, and identify them to determine whether their fermentation broth is effective.

It may be necessary to prepare tens of thousands or even tens of thousands of strains for screening.

Li Ang walked to the experimental bench silently. In fact, since the last Suzhou water poisoning epidemic successfully prepared artemisinin, he has been silently conducting experiments on the preparation of streptomycin.

But the amount of work was too large, so he sent Mosi's avatar to collect thousands of soil samples from different regions, trying to find usable Streptomyces, but nothing was found.

So much so that Li Ang began to gradually suspect that the soil in Yu State was not suitable enough, and he needed to go farther to collect soil samples.

Buzz——

Just as he was about to continue screening strains, the giant grasshopper-shaped close-legged insect placed on the table uttered a loud chirp.

Um?

Li Ang's hands paused. Due to the severe plague in Shuozhou, the traffic to the outside world was cut off, so he could only communicate with the outside world through letters and close worms.

It's getting late, who will call over?

Li Ang flicked the tentacles of the close worm and got through the communication, Hello.

Leon?

On the other end of the phone, there was the voice of Chen Danqiu offering wine. The background sound is the conversation of a group of people, some of which are familiar.

For example, Zhongshu ordered Xue Ji, Shangshu servant shot Pei Su, and Emperor Yu Li Shun.
