Penicillin is an important antibiotic with high efficiency, low toxicity and widespread clinical application. It was not widely used in Yihuan's time and space until 1943. If it could be developed in advance, it could greatly enhance human ability to resist bacterial infections and save tens of millions of lives.

It took more than two years from the construction of the factory to the development of sulfadiazine, and it took a lot of money. If it weren't for the help of Yi Yan in 1908, she had a relationship with the economic man of an English securities company in a securities company and made a lot of money by speculating on rubber stocks. She would have been unable to hold on any longer. Now that sulfadiazine has come out, the money is more abundant. With her gold fingers, those scientists from Citigroup would have been able to develop penicillin within three years.

That afternoon, Yi Li, the second master of the Yi family, came back with his wife and daughter. In early March, Lu Lanting's grandmother was seriously ill and sent a telegram to see her granddaughter. Yi Li, took his wife and daughter to Shanghai. Old Mrs. Lu took a few doses of medicine and her condition improved. She saw how many years would be better. Yi's father took Yi Li to the study to ask questions, and Yi's mother pulled Lu Lanting to ask some questions about her parents.

After dealing with her mother-in-law, Lu Lanting, who was obsessed with flowers, didn't care about the fatigue of the journey and went to the greenhouse to see the flowers. She met Yi Huan who came over with a specimen, "Second Sister-in-law."

From Yi Huan, he learned from his mouth that the carefully cultivated orchids bloomed in advance and were picked by Mu Xiaofeng. However, after seeing the specimens similar to flowers, Lu Lanting's anger was half gone. Then she thought that even if Mu Xiaofeng didn't pick them, she had been delayed for so long before she came back, and the flower was defeated, so she stopped getting angry and laughed and scolded, "This brat, I won't allow him to enter the greenhouse in the future."

The second batch of medicine arrived at the Jingu Port, and the person who received the goods sent a telegram to Zhou Zhennan, who went to Jingu to pick up the goods himself; now in Jizhou City, in addition to Fang Qing's private hospital using sulfadiazine, there are two other hospitals using it, which made the doctors and patients very satisfied. However, the medicine was used quite quickly, and it had reached a difficult point, and the price also rose accordingly.

Fang Qing had been coming to Yi Huan for three consecutive days. Yi Ou also discovered the business opportunities here and negotiated with Yi Huan to sell the medicine to the south. Yi Huan was just thinking about this, and the brother and sister hit it off. Yi Huan immediately sent a telegram to Citigroup, asking for an additional thirty boxes of goods to be shipped.

On August 31, after searching for such a day and still finding nothing, General Zhang was furious, but had to order the martial law to be lifted. The pressure of public opinion was too great, and the students who came back from the holiday organized two parades. Yi Huan was locked up at home and failed to participate. Mu Xiaofeng and Yi Haoran participated once, and the second time they were locked up at home and could not go out.

The next day, major schools in Jizhou City started school. Yi Huan is a student of Santa Maria Girls' School in Jizhou City. Originally, Yi Huan wanted her to drop out of school and get married, but Yi Huan firmly disagreed and went on a hunger strike to protest. Although Yi's father was tough, he was spoiled for his young daughter and was willing to force her to death. If he agreed, he would not drop out of school, but he would have to get married. But he didn't expect that the Wu family would break off the engagement, so the marriage would naturally end. Yi Huan was still sent to school by Brother Xiang in a rickshaw every day.

On the sixth day of the September 1st, Yi Huan thought this should be a normal autumn day. At five o'clock in the afternoon, after the etiquette class, Yi Huan and Zeng Shaowei walked out of the classroom with laughter.

"Huanhuan, have you received an invitation to Chen Huiping for a dance party?" Zeng Shaowei asked.

"Received." Yi Huan replied.

"Will you go?" Zeng Shaowei asked.

Yi Huan shook her head, "I don't want to go to school."

"I don't want to go either. She holds a dance party every few days, which is really annoying." Zeng Shaowei likes to play, but she is not very interested in dance parties, especially this kind of flattering dance party.

"She likes dancing." Yi Huan laughed.

Zeng Shaowei curled her lips, "She is just a slut. She likes to twist her waist and butt. She likes dancing so much, so she just goes to Paramount to be listed, and she has to dance every day."

Yi Huan raised her hand and pounded her, saying, "Don't talk nonsense, it's bad for people to hear it." Don't fight against the rich, and don't fight against the officials. Although the Zeng family has money, the Chen family has power.

Zeng Shaowei stuck out her tongue.

While talking, the two of them were about to reach the school gate. Zeng Shaowei suddenly screamed, "Oh!"

"What's wrong with you? You're shocked and what's wrong." Yi Huan glanced at her sideways.

"I forgot the book in the classroom." Zeng Shaowei frowned.

"What book?" Yi Huan asked.

Zeng Shaowei looked around and whispered: "The Old System and the Great Revolution."

Yi Huan's eyelids twitched and asked, "Who lent you? Do you want me to go back with you to get it?"

"I stole my second brother's, do you want to see it?" Zeng Shaowei asked.

"No interest." Yi Huan shook her head. The situations of the two countries were different, and there was no possibility of learning from them. Besides, she was not a material for revolution. She was just doing business and earning more money, so that Zhou Zhennan could recruit more people to increase capital for the future national war of resistance.

"You go first, don't wait for me." Zeng Shaowei said that, turned around and ran back.

Yi Huan snorted: "Slow down, don't fall."

"I understand." Zeng Shaowei's voice came from afar.

Yi Huan walked to the school gate and found that it was not Brother Xiang who usually came to pick her up, but her third brother Yi Yan. He asked in surprise: "Three Brother, why are you here to pick me up? Where is Brother Xiang?"

"Get into the car quickly." Yi Yan opened the car door.

Yi Huan sat in, Yi Yan sat in the cab, drove away from the school and headed straight to Yi Mansion; Yi Huan asked, "San brother, is something wrong?"

"Zhang Jun and Yan Jun fought outside the city." Yi Yan said simply.

Yi Huan frowned, "Will Jizhou City change its ownership again?" In the year of Yi Huan's birth, the last emperor abdicated and the Wei army formed the Republic of China government; at the age of three, the Wei army fought against Feng Jun, and Feng Jun won, and entered Jizhou City; at the age of five, Feng Jun and Zhang Jun confronted each other, and Feng Jun won again; at the age of nine, Zhang Jun made a comeback, Feng Jun was defeated, and the coalition army officially took over Jizhou City; last year, Duan Governor was restored and was killed by Zhang Jun's men. Since then, Zhang Jun dominated the city, but only one year of peace, and the war broke out again. Who will be the winner this time?

"It's possible." Yi Yan could not be sure, and the situation is still unclear.

"When will this battle end?" Yi Huan looked forward to peace. She resisted this turbulent era from the bottom of her heart, but she couldn't go back.

Although this place is different from what she learned in history books, the same warlords are divided, the same wars are flying, surrounded by the great powers, and the people are living a miserable and miserable life, and the day is in danger.

Yi Yan pursed his lips and said nothing, and he couldn't answer this question.

The car drove outside the Yi Mansion. Yi Yan called the horn three times. The servant opened the door. The car drove in. The servant closed the door again with neat movement. Yi Yan parked the car, the brother and sister got down and walked into the house. Before he entered the door, Yi Huan heard his mother asking, "Why haven't Ah Yu brought Xiao Si back yet?"
