Three days later, Kitayama Laboratory.

Zhou Heng followed Su Xianling to the microscope and carefully identified the slide under the eyepiece.

Like a bamboo, long black slender cells appeared in front of him, Zhou Heng shuddered, blinked and looked at it carefully, and then raised his head.

He thought about many possibilities, if he couldn't cultivate it, then the malaria caused by Salmonella was one of the culprits, but he never expected it to be Bacillus anthracis, and the power of this thing was even more terrifying.

Zhou Heng raised his eyes to look at Su Xianling, and his face instantly carried a rare seriousness.

"When you make petri dishes, do you take strict precautions?"

Su Xianling didn't know what this meant, but seeing Zhou Heng so solemn and knowing the seriousness of this matter, he quickly nodded and said:

"Childe rest assured, this petri dish is made separately, and the incubator is put on it separately, for fear of mixing with others and affecting the final observation, every time I observe, I see the strain growing, so I invite you to come over, Childe, what kind of germ is this?"

Zhou Heng nodded, breathed a sigh of relief, and hurriedly put the slide in a closed glass box, turned around and sprayed his hands with alcohol, and threw it to Su Xianling Alcohol bottle, signaling him to disinfect it like himself.

"This thing is very scary, when we didn't make penicillin, it was a kind of disease that could not be cured, after being infected, symptoms would appear in half a day to five days, and people would die quickly in three or two days after a high fever, and even if they survived, they would be disabled, or missing limbs.

By the way, you have been in the Tai Hospital for many years, did you know about the plague in Fujian ten years ago? ”

Su Xianling thought about it, turned around and opened a cabinet, took out a stack of books, some of which were already very old, rummaged through them, took out one of the booklets, and finally stopped on a page and returned to Zhou Heng's side.

"Childe, please see, when we were researching new drugs before, I brought all the booklets recorded by the Tai Hospital, these are all old records of the plague, I have been in the Tai Hospital for 16 years, and all the large and small epidemics I have experienced or heard about have been recorded.

This is the record of the plague in Fujian, there are later statistics on it, the symptoms are very similar to what you said, the high fever is highly contagious, and people in villages are dying, even if they are alive, they are not broken hands and feet, they are also stupid. ”

Zhou Heng hurriedly took it over and looked at it, it was obvious that this was the data of many statistics, and the course of the disease and the record of symptoms were indeed very similar to the Bacillus anthracis infection.

Zhou Heng closed the booklet and looked at Su Xianling.

"I didn't say what method was used to control the epidemic in the end, have you heard of it?"

The expression on Su Xianling's face was suddenly very strange, and seeing that Zhou Heng was waiting for his answer, he didn't dare to hide it, and arched his hand and said:

"From ancient times to the present, many incurable epidemics, the ultimate means is to slaughter the city, that is, to gather all the sick people together, shoot and burn to death, and the whole city chickens and dogs are not left, in order to control the epidemic, although it is cruel, but in order to let someone live, it is also a last resort."

Zhou Heng was silent, although cruel, but this is indeed the only way to keep people who are not ill alive without medicine, needless to say that Fujian must have been full of corpses back then, and the slaughter of the city is definitely a huge number.

"The petri dish is stored separately in a glass box, and it can't be in contact with any petri dish, you lock it up, and I'll be useful later, as for the tip of the knife...... Let's put it together, by the way, have you ever seen anyone use a knife like this? ”

Su Xianling thought for a while, and when Zhou Heng spoke, he held up a piece of paper and drew several possibilities according to the shape of the tip of the knife, and Su Xianling's eyes suddenly widened.

"I seem to have seen it, it turns out that the hospital envoy seems to have such a golden knife, he is better at injuries, someone injured an arm or leg will curl up, he uses this to treat, of course, I now know the reason, and I also know the surgical method, but at that time it seems that this method was very popular in the hospital."

Zhou Heng narrowed his eyes, this statement made him immediately interested.

"Popular? That is, many people have built such knives? ”

Su Xianling nodded, "Yes, at first it was his disciple, and later the hospital sentenced the doctor, whoever has seen it wants to make a hand, after all, it seems that the medical skills are more sophisticated, but this knife is not something that anyone can build, I remember that only a jewelry shop in the capital can do it, after all, ordinary gold and silver are too soft and not sharp enough." ”

Zhou Heng nodded, understanding what Su Xianling meant, in fact, this is the alloy, he looked at it carefully before, this knife tip is indeed very sharp, even if the rust on it is scraped clean for ten years, the sharp knife tip can still be seen.

"Do you know what kind of shop it is?"

"This shop is called Sanwu Pavilion, who the owner is I don't know, I can only see the shopkeeper's care, everyone says that the owner is a knowledgeable person, this name is unforgettable, all the big families do not go to the Sanwu Pavilion."

Zhou Heng nodded and smiled at Su Xianling.

"Okay, you know what happened today, these strains are well preserved, and if they spread, they will cause an epidemic."

After saying that, Zhou Heng left, and returned to the office of the medical school, and a figure flashed from behind the door.

Zhou Heng just closed the door, and he was not surprised to see that person, after all, it was already the norm for Pang Xiao to suddenly appear like this, since he could stand here safely, the surroundings were naturally safe.

"Xiao Bo, sit down."

Pang Xiao was not polite, and quickly sat down.

"I wonder what Uncle has discovered?"

Zhou Heng sat down close to Pang Xiao, and carefully talked about the discovery with Su Xianling just now, from the plague records in Fujian, as well as the state of this disease, and the origin of the knife, the more Pang Xiao listened, the more frowning he became, and finally looked up at Zhou Heng after being silent for a long time.

Zhou Hengbian said that he had already started and drew the shape of the knife, as the housekeeping ability of the previous envoy, these people are very familiar with this thing, whether they are sought after or really believed.

However, this thing is just like the small needle knife that was popular in later generations, people who can use it may be able to use it, and some of the effects, people who can't use it, or people who can't master it, this is a murderous weapon, and the danger factor is far higher than the effect.

"Sanwu Pavilion, I remember, I will investigate, as long as there is a direction."

After saying that, he folded the drawing and put it away, and then continued:

"The prince already knows about your autopsy, let me convey a thank you, this is also a matter of the prince's heart."

Zhou Heng waved his hand, in fact, the death of the eldest prince, if he was to think that it was the old emperor who made a move, a son who can fight well, if the wings are gradually full, wouldn't there be one more King Ning, and the old emperor's sons are not as good as him, and fear is a must.

Kill it, this is the most suitable time, King Ning thought so in his heart, naturally it was right, and the murderer also took advantage of this, after all, from the perspective of the beneficiary and the analysis of the way the anthrax bacillus was obtained, the possibility of the Wen family was too great, but there was no evidence.

"Xiao Bo be careful, the capital has been investigating the matter of the Golden Crow Sect, don't be implicated because of this."

Pang Xiao smiled and bowed.

"Thank you for your concern, I'll take the lead!"

Zhou Heng didn't say anything, Pang Xiao had already dodged away, the old man came and went without a sound, but he felt that the breeze in front of his face was floating, and there was no trace of the person.

Shaking his head, Zhou Heng stepped out of the office, went downstairs and walked to the opposite teaching and research room, where there were all people studying, but Zhou Heng didn't stop and walked directly to the top floor, pushing open the largest ward, Zhang Jingrui and Mingyu turned their heads to look at Zhou Heng together.

"Childe (uncle), you're here!"

Saying that, the two of them hurriedly stood up honestly, Mingyu didn't have too much expression on his face, he bowed his head and lowered his head, Zhang Jingrui was much more lively except for the inconvenience of his left hand, and looked at Zhou Heng with a smile.

"How's the review, you two?"

Mingyu is an honest man, he came here to study, Zhou Heng said it a long time ago, it was to help Zhang Jingrui review, in Zhou Heng's words, if he learns to be able to speak, he can be two percent higher than he understands, if he teaches others, he can be two percent higher, Mingyu made sense when he heard it, so he didn't resist and followed.

"I just memorized the ninety-nine multiplication table and division table, and I am not proficient in using it, as for the poetry Zhang Gongzi's ability is not weaker than me, we haven't practiced the strategy, and the various topics listed before were just copied yesterday."

Zhou Heng nodded, Zhang Zhongtang's son, even if he can't pass the exam, he has a foundation, it's not bad, it may be that he didn't play well, or it may be that someone else stumbled, after all, with such an upright father, Zhang Jingrui was also unlucky.

"Show me what Zhang Gongzi wrote."

Since Zhang Jingrui was rescued by Zhou Heng, he can be said to be obedient to Zhou Heng.

Especially in the past few days when he came to Beishan, in the process of Mingyu's brainwashing, he found that Zhou Heng had a deep accomplishment in arithmetic and literature, and he admired the five-body casting.

Seeing what Zhou Heng wanted to write by himself, his face was a little red, and he quickly found a strategy and handed it over.

Zhou Heng took it and read it again, these people who are full of great truths are also dizzy about your strategy, Zhou Heng is not interested at all, but after reading Zhang Jingrui's handwriting, he kept nodding and said:

"Your handwriting is very easy to read, and you can see that this is a child's skill, but it ......"

Speaking of just two words, Zhang Jingrui came closer, this word is what he is most proud of, after all, it was taught by his father, and he will be praised at any time, but he didn't expect Zhou Heng to have objections to this.

"But it's not good to be too recognizable, but if you show your handwriting to others, you can guess who you are without looking at the content, right?"

Zhang Jingrui didn't understand, but he nodded after listening.

"That's true, my father once took the calligraphy I wrote out to show people, and among the younger generation, in terms of calligraphy alone, if there is a ranking, my father said that I can still count in the top three."

Zhou Heng returned the strategy to Zhang Jingrui, and said earnestly:

"Here's the problem, I hope you can exercise your left hand to write, or change the font, at least so that people don't know at a glance that this is your handwriting, so that people can focus on your answers, poems, and theories, so as not to move some minds that shouldn't be there."

Zhang Jingrui opened his mouth and looked surprised, thinking about Zhou Heng's words, he instantly understood the key, he had experienced a lot of things after studying for many years, after all, he was still older than Mingyu and Zhou Heng, he was not stupid.

"Thank you for mentioning it, my left hand is inconvenient now, but with some effort, I can still change the font."

Zhou Heng smiled, it's good to understand this.

"Okay, according to the arithmetic questions I gave to Mingyu before, you can start training, this multiplication and division formula must be memorized, as for the poems, they will also write ten articles according to the questions I came up with, and then let me screen, the autumn is coming, you need to work hard."

Mingyu took out a stack of test questions, on which were planted trees, bricks and river lengths were calculated, for Zhou Heng, these were all third-grade mathematics, but in this world, these arithmetic questions are already quite difficult.

Zhang Jingrui looked embarrassed, "Mingyu has shown it to me just now, I can still calculate it according to the formula for my simple calculations, but these test questions are too difficult, and I don't know what it means after turning several corners, it is addition and subtraction and average." ”

Zhou Heng glanced at him, he didn't want to continue such a non-technical topic.

"Take your time, arithmetic is to see the types of test questions, so that you don't lose points in the calculation, and the strategy depends on the aesthetic standards of the examiner, I can't weigh this, I can only let you practice more, I can help you take a look at the poems, go and take out all your poems, according to the order of the questions I give you."

Zhang Jingrui hurriedly got up, this was ready, took a few booklets, looked at the title category of the cover, this kid was still serious, and even copied the poems and texts into the books of various categories.

Zhou Heng looked through it, and he knew it in his heart, and made annotations on the poems he wrote, and of course used his experience of 300 Tang poems to integrate some more classic verses.

Zhang Jingrui was surprised, much calmer than Mingyu, and patted Zhang Jingrui on the shoulder, so that he wouldn't be surprised and look carefully.

"Be calm, there are few people in the world who can match Childe's poems, haven't you bought them before?"

Zhang Jingrui blinked, "I bought it, but I didn't take it seriously at that time, after all, ...... After all, Uncle Zhou was the imperial doctor at that time, so he ......"

Zhou Heng doesn't care at all, there are many people who think like this, although Liang is civilized, the standard for looking at people is still the same, even if a doctor's poems are good, they can't be on the stage.

Finished the last volume and threw it to Zhang Jingrui.

"Okay, don't think about it so much, I don't want to be an official, it's useless for me to get fame, the two of you learn from each other's strengths, arithmetic and poetry Mingyu help Zhang Gongzi more, and Zhang Gongzi helps Mingyu control more.

As for the content, I said, don't die reading, those useless, such as arithmetic learning just know the mantra, is it right? You also have to really apply, only if you can use and see the use of these methods, you can be considered will, and you must also have your own vision for policy, just a good article but a biased vision will not be reused.

There are still more than ten days before the autumn season, and I think there is still plenty of time, so you can review well. ”

The two of them stood up, gave Zhou Heng a salute in a proper manner, and Zhou Heng got up and left.

As soon as he returned to the office, Zhou Heng looked through a few books, and listened to Fang Hua talk about the recent situation in Beishan, Boss Xue walked in quickly, and it was rare to give a formal salute.

"Childe, Gongzi Zhang's father is here, just outside the hospital!"

Zhou Heng was stunned, this time was pinched, not long after he went to see Zhang Gongzi, he came.

"Don't be stunned, please come in!"

Fang Hua stood up with a smile and picked up the counted accounts.

"Zhang Zhongtang is probably worried about Zhang Gongzi's body, so I still hurried to get busy, Fujian just came back and was unloading."

Zhou Heng waved his hand, Fang Hua was still reliable, he didn't think he was an uncle when he came to Beishan, and now he took over a lot of Zhu Sanfu's work, Zhou Heng came back to see it, and saw that everything was running normally, so he let him manage it like this, anyway, according to the old emperor's intentions, he will live in Beishan in the future.

"Go get busy, pay attention to the hot weather and don't get heat stroke!"

Fang Hua grinned happily.

"I'm not tired, the canteen has already ordered mung bean soup to be made, and it is chilled and distributed to the personnel everywhere, so I'll leave."

Zhou Heng didn't say much polite to him, as soon as Fang Hua went out, Zhang Zhongtang came in, he looked at Zhou Heng and didn't sit down, tidied up his robe, and solemnly gave Zhou Heng a salute.

Zhou Heng was startled and quickly staggered his body.

"Zhang Zhongtang, what does this mean?"
