"I see."
Li Ang raised his head and forced a smile, "Where is your teacher Qiu?"
"She's already asleep."
"Then you should go and have a rest. Everyone is very tired during this period. I'm just responsible here."
Li Ang patted his apprentice on the shoulder and asked the girl to go back to the temporary dormitory upstairs, while he walked out of the house holding hot tea.
The autumn wind is bleak and fallen leaves are flying. There are no people on the street, only soldiers and government servants wearing masks and colorful armbands, delivering meat, grain and today's epidemic bulletin from house to house.
The air was filled with a strong and choking smell of sulfur. Although it was unpleasant, it was still better than the horrible stench that enveloped the city some time ago.
"Want some?"
A rough voice sounded from the side. Li Ang turned around and saw Yan Yundang, wearing armor and holding a horse in his hand, standing at the door like an ordinary soldier. He also held an ox horn wine bag in his left hand.
"No."
Li Ang shook his head, "I just had tea."
"You are the most un-Yu-guo person I have ever seen."
Yan Yundang shook his head, opened the wine bag with one hand, and took a sip of strong liquor. "I don't drink even a drop of wine. I don't look like a disciple of the academy, but more like an ascetic."
"I prefer to stay awake."
Li Ang smiled slightly. Perhaps it was the inertia of his status as a surgeon from another world. He almost never drank. Even when he attended Song Shaoyuan's last wedding as the best man, he only drank a few drinks.
"Although I don't drink, I actually have a good drinking capacity. Doctors use alcohol to disinfect their palms 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 amount of alcohol in disguise.
"
"You kid will say things that ordinary people can't understand.
If you don’t drink, life will lose a lot of fun.”
After drinking strong wine, Yan Yundang smacked his lips and squinted his eyes and said: "The people of the Yu country are too bitter. Before the invention of the aura locomotive, before the invention of allicin and penicillin, every farewell might be an eternal farewell.
I couldn't express my emotions, so I could only drink.
That’s why there are farewell wines, reunion wines, leaving the pavilion wines, and strong travel wines.”
He paused for a moment and said calmly: "In the autumn of the second year of Tianshou, the Turkic army invaded the border of Yu State. I left my pregnant wife and went out with the army to station in Luanshi City.
The Turkic cavalry cut across the northern border, the cities fell one by one, and the stone city was reduced to an isolated city.
The siege lasted for five months. We ran out of arrows and food, and our comrades around us fell one by one. We had to stand at the top of the city and stone the enemies who tried to climb up the wall to protect the remaining nuns.
The lieutenant who scolded the Turkic barbarians with you during the day died quietly one night due to diseases such as blood carbuncle.
Without the general, deputy general, and captain, the last 300 comrades in the city gathered together to discuss for a while, and finally selected 20 people, including me, who took advantage of the night to travel lightly on horseback to the rear of the Turkic army.
Burning their food supplies.
The plan was successful, and the flames ignited by the grain and grass rose into the sky.
The sound of curses in Turkic language, the sound of horse hooves, and the sound of chanting instruments piercing the sky reached my ears.
The arrows came like a scattered rainstorm.
A team of twenty people attacked the enemy formation, but in the end I was the only one who escaped.
In the early morning of the next day, the Turkic army finally retreated. And the scouts in the rear also sent a letter from my hometown - my wife had given birth normally, and mother and son were safe.
That day was the best drink I’ve ever had.”
He looked at the silent city in front of him, which had witnessed too many life and death during this period. He turned to the silent Li Ang and said calmly: "The way of heaven reincarnates, life and death are as usual.
Don’t be too hard on yourself.”
"Um."
Li Ang nodded, reacted belatedly, and said with a smile: "In addition to being a doorman, why do you also work part-time as a psychotherapist?
Also, why don’t you wear a mask?”
"Good intentions are regarded as the liver and lungs of a donkey."
Yan Yundang rolled his eyes, but he still took out the mask from his arms and put it on his face, "I am a martial arts master, how can I get sick so easily."
"You said the same thing before you got anemia, right?"
Li Ang unceremoniously exposed Yan Yundang's lies and said seriously: "The plague is extraordinary, we must pay more attention to it."
"I know, I know."
Yan Yundang waved his hands impatiently, "I'm here to guard the door. You can go back to sleep."
After curing his anemia, Yan Yundang is still one of the strongest martial arts masters in the world. With him as the guard, Li Ang can indeed sleep well.
However, he still couldn't sleep.
To contain the plague, it is not enough to rely solely on isolation and cutting off the chain of human-to-human transmission.
It is necessary to produce a specific drug that can treat plague as soon as possible, so that the number of deaths can be reduced as quickly as possible, and the plague can be removed from the position of a terminal disease that is difficult to treat with medicine and stone.
Li Ang shuffled to the basement, flipped the button on the wall and turned on the talisman lamp.
When the lights came on, I saw that the basement was full of test tubes, flasks, centrifuges and other experimental instruments, and all kinds of data were densely written on the blackboard.
Drugs against plague include aminoglycosides, fluoroquinolones, third-generation cephalosporins, tetracyclines, gentamicin, kanamycin, amikacin, etc.
But the most effective and obvious effect against the three plague diseases is still streptomycin.
It is an antibiotic extracted from the culture fluid of Streptomyces griseus. It can act on the ribosomes in bacteria, inhibit bacterial protein synthesis, destroy the integrity of bacterial cell membranes, and then kill bacteria.
"Streptomycetes are mainly distributed in the soil, and there are thousands of species. We need to find suitable Streptomyces, culture, isolate and identify them to determine whether their fermentation broth is effective.
Just for the strains used for screening, tens of thousands or even tens of thousands of them may need to be prepared.”
Li Ang walked to the experimental table in silence. In fact, he had been silently conducting experiments on preparing streptomycin since artemisinin was successfully prepared during the last water poisoning epidemic in Suzhou.
But the workload of the project was too large, so he sent a clone of Mosi to collect thousands of soil samples from different areas, trying to find usable Streptomyces, but nothing was found.
So much so that Li Ang gradually began to wonder whether the soil in Yu State was not suitable enough and he needed to collect soil samples from farther away.
Buzz——
Just when he was about to continue screening strains, the giant grasshopper-shaped close insect placed on the table made a loud chirp.
"Um?"
Li Ang made a move with his hands. Due to the severe plague in Shuozhou, outside traffic was cut off, so he could only communicate with the outside world through letters and close insects.
It's getting late, who's going to "call"?
Li Ang moved the tentacles of the close insect and connected the communication, "Hello."
"Li Ang?"
On the other end of the phone, the voice of Chen Danqiu, who was offering wine, came. The background sound was the conversation of a group of people, some of which were familiar.
Such as Zhongshu Ling Xue Ji, Shangshu Pushe Pei Su, and Emperor Li Shun of Yu State.
