"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 will be 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 the fallen leaves are flying. No people could be seen on the streets, only soldiers and government servants wearing masks and colorful armbands were delivering meat, grain and today's epidemic bulletin from door to door.
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, and Li Ang turned around and saw Yan Yundang standing at the door like an ordinary old soldier wearing armor and holding a horse-steed, with a 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 any alcohol. 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.
Without drinking, life will lose a lot of fun. "
After drinking the strong drink, Yan Yundang smacked his lips and said with squinted eyes: "The people of Yu State 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 Zhuangxing wines...”
He paused and said calmly: "In the autumn of the second year of Tianshou, the Turkic army invaded the border of Yu Kingdom. I left my pregnant wife and went out with the army to station in Luanshi City.
Yawenba
The Turkic cavalry cut across the northern border, and the cities fell one by one, and the stone city was reduced to an isolated city.
The siege lasted for five months. We lost arrows, ran out of 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, to take advantage of the night and 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 curses of Turkic words, the sound of horse hooves, and the sound of telegraph instruments piercing the sky all reached my ears.
Missing 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.
Early the next morning, the Turkic army finally retreated. The scouts at the rear also sent a letter from my hometown - my wife had a normal birth and my mother and son were safe.
That day was the best drink I had ever had. "
He looked at the silent city in front of him, which had witnessed too many lives and deaths during this period, and 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 hand impatiently, "I'll be the gatekeeper here. You can go back to sleep."
After curing the stubborn disease of 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.
Still, he couldn't sleep.
To contain the plague, isolation alone is not enough to cut off the chain of human-to-human transmission.
It is necessary to produce a specific medicine 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 rune lamp.
When the lights came on, I saw that the basement was full of experimental equipment 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, etc.
But among the three plague diseases, the most effective and obvious one 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 first, culture, isolate and identify them to determine whether their fermentation broth is effective.
Just for the strains used for screening, tens or even tens of thousands of strains 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 the last time he successfully prepared artemisinin during the Suzhou water poisoning epidemic.
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 further places.
Buzz——
Just when he was about to continue screening strains, the giant grasshopper-shaped chinch bug placed on the table began to chirp loudly.
"Um?"
Li Ang made a move with his hands. Due to the serious plague in Shuozhou, outside traffic was cut off, and he could only communicate with the outside world through letters and Chi Chi Chong.
It's getting late, who's going to "call"?
Li Ang moved the tentacles of the chichi 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 chatter of a group of people, some of whom were familiar.
For example, Zhongshu ordered Xue Ji, Shangshu Pushe Pei Su, and Emperor Li Shun of Yu State.
