When Oxford County was snowy, Chu Yun's mansion was also covered with snow. The guards outside the mansion exhaled white breath and looked at the occasionally passing pedestrians on the street.

A woman came to the military master's mansion with an umbrella. The guards who knew her said enthusiastically: "Hello Miss Liu."

"Hello, sir." Liu Rushi nodded to them, put away the oil-paper umbrella, and then entered the military master's mansion.

Several guards saw Liu Rushi entering the mansion and said privately: "Miss Liu is still so polite. If one day he could marry such a wife, I don't know how lucky he would be."

"Just think about it. How could we guards marry such a woman? It's better to find a good wife to have a good birth..."

"Ahem, don't whisper. Miss Liu is a guest of the military lord's mansion, so don't talk about it!" Guardian Yu Cheng came to patrol and shouted at these deserted guards.

"Yes!" Several guards quickly straightened their bodies.

Liu Rushi is usually one of the teachers responsible for teaching Ling'er. Because she has to be busy with her own studies, she only needs to come over to supervise Ling'er's study situation on weekends.

After winter, there is also a winter vacation in the Capital University, so Liu Rushi has a lot more time to arrive at the Military Lord's Mansion after he has time.

Chu Yun had just gotten up and brought a basin of warm water to wash it in the patio in the backyard. While rinsing his mouth, he muttered: "Heavy snow indicates a good harvest, and no snow will cause disaster. I hope next year will be a good harvest, so I will stock up more food..."

"Mr. Master..." Liu Rushi found Chu Yun who was still washing up, and thought he had come too early.

But she thought about it carefully and it seemed that there was no difference between the time she arrived normally.

Chu Yun didn't think anything was there. Liu Rushi had a good relationship with Ella and Da Yuer, and I don't know how many times the patio in the backyard came: "Oh, are you here? Ling'er, come out quickly."

However, the room in the backyard was quiet and there was no movement.

"Sir, have you forgotten? Ling'er and Xue'er were sent to Xiao Xiu'er's place for the night yesterday."

Ella and Da Yuer came out of Chu Yun's room and found that Liu Rushi was coming. Both of them had a red cheek.

"I forgot if you don't say it..." Chu Yun was also a little embarrassed.

Liu Rushi understood why he arrived on time today, and Chu Yun and the other two had just stood up.

Well...it's better to pretend not to understand anything.

After about a while, Xiao Xiu'er brought Ling'er and Xue'er back.

Xiao Xiu'er understood that Chu Yun and others would send Ling'er and Xue'er to her place for the night from time to time, but this was not a embarrassing thing for her who was studying medicine.

"Hello sir." Ling'er was very awe of Liu Rushi. When she saw Liu Rushi coming to check her homework again, she hid behind Xiao Xiu'er and said hello to Liu Rushi.

"Ling'er, can you calculate the multiplication and division of three digits?" Liu Rushi asked with a smile.

Ling'er nodded nervously.

"Sister Liu Rushi, are the content you and other teachers taught too advanced..." Xiao Xiu'er has a good relationship with Ling'er because she sometimes has to help take care of Ling'er. When she saw that Liu Rushi and other family lecturers had taught Ling'er three-digit multiplication and division, she always felt a little incredible.

"With his talent, he should be able to keep up." Liu Rushi said.

Liu Rushi then began to check the two subjects of Chinese and arithmetic that Ling'er learned from other teachers this week.

“What a peaceful winter.”

After washing up, Chu Yun returned to the room. There was a warm stove, Da Yu'er helped make tea, and Ling'er's sound of reading aloud in the backyard lobby. As for his daughter Chu Xueer, she was still in the cradle.

It was undoubtedly a very peaceful day for him who didn't have to deal with affairs on this day. He didn't know that the officers stationed overseas were still thinking about how to train soldiers and start wars. He didn't know that the civil war in Britain had already broken out early, and Sun Chuanting even helped Charles I train the army.

"The short-tailed dwarf kangaroo in the courtyard has a new litter of kangaroos. I have asked me to move them to the demolition house temporarily, otherwise I might not be able to survive this cold winter." Aila held a volume of "Red Fu Ji" by Zhang Fengyi, a Ming man in her hand, and remembered the strange pets in the military master's mansion.

The expedition team heading to Oceania to open up land has sent back two short-tailed dwarf kangaroos, and they have been kept in the military master's mansion, and have unknowingly reproduced two offspring.

"These little guys only give birth to one offspring every year, and their reproduction ability is very poor... In the future, our capital will build a Botanical Garden of All Nations, and concentrate representative animals and animals from various places here. As factories are established and primitive places are developed, many species will perish. If various important species can be collected here through such a botanical garden, it may be a good thing for future generations." Chu Yun thought of himself as he had the idea of ​​establishing a Botanical Garden a long time ago.

If some species are collected in advance, then the dodo, Antarctic wolf, and Chinese rhino will not become extinct.

"Many plants and animals have the value of research, and we can get some inspiration from it." Xiao Xiuer agrees with the practice of maintaining species diversity.

"Have your medical department been studying something recently?" Chu Yun asked.

"Some people are studying rabies vaccines, some are studying antimalarial drugs, some are studying gastroscopy, and some are studying hemostatic forceps, tourniquets and vascular ligation. It depends on the direction the research team is specializing in." Xiao Xiuer replied.

Chu Yun nodded with satisfaction, and it seemed that the medical department was also developing rapidly with a good momentum.

The medical department has become many disciplines, and different projects are underway, and various vaccines, drugs, and medical devices have been invented. In addition, there are also their own hospitals and nurse schools to cultivate talents in this field.

"But we haven't found the penicillium you mentioned yet... Can penicillium extracted from penicillium really be efficient in treating bacterial infections and have few side effects?" Xiao Xiu'er took this opportunity to ask Chu Yun.

Just when the Medical Department was established and the invention of various drugs and instruments was vigorously developed, Chu Yun occasionally thought of an important drug - antibiotics.

Bacterial infection in wounds is a terrible thing. At present, it is only possible to reduce bacterial infections by simple disinfection measures. Most injured soldiers and civilians die not because they are hit by the key points, but because they are infected by bacteria.

If antibiotics represented by penicillin can be purified, it is hard to imagine how many people can be saved and how much profit can be created every year...

"The new silver dollars issued by Jiuzhou Bank have been widely used by foreign trade merchants, so Jiuzhou Bank has recently minted more silver dollars through the recycled silver, and the head office has begun to encourage the recycling of gold from overseas in private trade..." Da Yuer, who took office in the Finance Research Committee, also took advantage of the peaceful day to provide Chu Yun with some important information.
