Lu Jiao used seven days to extract the penicillin spore culture, and then she used sterile water to inoculate the spore suspension into the sterilized culture medium containing Lingquan water in the seed tank.

To be honest, if there is no spiritual spring water, it is quite difficult to extract the penicillin liquid, but Lu Jiao decided to do an experiment later, to test out a base liquid to replace the spiritual spring water, otherwise the penicillin liquid has been cultivated by her spiritual spring water It's unrealistic. If she dies in the future, penicillin will no longer be able to be produced, so she must develop a base solution to replace Lingquan water.

In the laboratory, besides cultivating the penicillin solution, Lu Jiao also extracted potassium from the potassium brine.

She was busy inside, when someone knocked on the door outside, Feng Zhi shouted from outside: "Ma'am, County Lord Wen'an is here."

Lu Jiao had a look of disbelief, thinking that she had misheard, so she asked Zhou Shaogong to deliver the letter to Zhao Lingfeng, and in just over ten days, County Lord Wen'an rushed over from the capital, is it true?

Lu Jiao walked to the door, opened the door and asked Feng Zhi outside: "Is it true?"

"Really, the county lord is waiting in the main hall of the front yard right now."

Lu Jiao went out immediately, Feng Zhi and Ruan Zhu hurriedly followed, and the group went straight to the main hall of the front yard.

In the main hall, County Mistress Wen'an was walking back and forth anxiously. Her mood was a bit out of place. A tall and straight young man next to her was very worried and advised him gently.

"Mother, don't worry, we will definitely find my sister this time, so don't panic yourself, if my sister sees you like this, she will definitely blame herself, and she won't blame you."

After listening to his son's words, County Lord Wen'an was quiet for a while, and Lu Jiao led someone in outside the door, and respectfully saluted County Lord Wen'an: "I have met County Lord Wen'an, the son of Duke Wu."

The eldest son Nie Yeling has resolute features, clear eyebrows and eyes, and calm and measured gestures. As the eldest son of the Duke of Wu, he is not at all like the second son Nie Yezhen who doesn't distinguish between right and wrong.

County Lord Wen'an saw Lu Jiao, and immediately stretched out his hand to pull her up excitedly: "Jiaojiao, is what you said before true? Have you found my daughter? How is my daughter? She has been doing well these years Is it? Did you suffer a lot?"

At the end she started crying, Lu Jiao hurriedly pulled her to sit down, and said comfortingly, "Master, don't worry, listen to me slowly."

After hearing Lu Jiao's words, County Lord Wen'an calmed down a bit, but his eyes were still red, and there was worry on his face, as if he was very afraid of hearing the news that his daughter was doing badly.

Lu Jiao took her hand and said, "Master, listen to me first, I'm not sure that my sister is your daughter."

As soon as Lu Jiao finished speaking, Nie Yeling, the eldest son of Duke Wu, showed suspicion on his face. Could this woman take the opportunity to curry favor with his sister?

Nie Yeling couldn't help but asked, "Why do you call her sister?"

Lu Jiao looked up and saw Nie Yeling's suspicious expression, and immediately understood that he thought she knew Li Yuyao's identity, and was flattering Li Yuyao.

Lu Jiao immediately curled her lips into a sneer: "Your Majesty thinks too much. When my sister and I sworn sisters, I didn't know that she was the lord of your Duke of Wu's mansion. At that time, she had dystocia, and she would die twice. I will replace her." I underwent a laparotomy operation to save their mother and son's lives, but my sister insisted on recognizing me as my younger sister, so we became godsisters."

After she finished speaking, she continued: "Besides, there is no way to prove that my sister is the township lord of your Duke Wu's mansion."

Lu Jiao was a little annoyed, and the County Mistress Wen'an immediately grabbed her heart. She held Lu Jiao's hand tightly, turned around and glared at her son, "Shut up, you have your business everywhere. Why do you always think of others so badly?"

Nie Yeling, the eldest son of Duke Wu, smiled wryly: "Mother, I know I was wrong."

After he finished speaking, he turned around and apologized to Lu Jiao: "Madam Xie, I'm sorry."

Lu Jiao ignored him, turned her head to Wen'an county master and said, "Sister Li?"

Lu Jiao stopped calling sister Li Yuyao, and added a surname in front to avoid suspicion.

It's just that when she yelled like this, County Mistress Wen'an heard it. She immediately became nervous and stopped Lu Jiao and said, "Jiaojiao, you don't have to think about it. You and my daughter can be called whatever you used to call them."

If it was because of them that her daughter and Lu Jiao had an identity, her daughter might be annoyed.

Lu Jiao thought about it for a while, but she was quite calm. When she and Li Yuyao became sworn brothers, no one from Duke Wu's mansion knew where they were.

"Sister, she is the daughter of Li Juren, married to the county magistrate, and now has a son and a daughter. She is extremely kind and kind. In fact, when I saw the county magistrate last time when I came to Beijing, I thought of her, but because I haven't heard my sister say that she is not the daughter of the Li family, so I dare not say anything more."

"This time when I went back to Ningzhou, my sister always had nightmares. I asked her what kind of nightmares she had. She said that she and several children were locked in a cage, and then someone let them go. She ran desperately. Running desperately, it seems that I hit a carriage from behind."

"As soon as I heard her dream, I suspected that she was locked in a cage by human traffickers..."

Just as Lu Jiao said this, County Mistress Wen'an couldn't stop crying. She held onto Lu Jiao's hand tightly: "My poor daughter, she has suffered so much at such a young age."

The eldest son Nie Yeling and the county lord's mother and maid all cried sadly.

Xiangjun has suffered so much at such a young age, how could they not feel uncomfortable hearing this.

Seeing that Wen'an county magistrate was about to faint from crying, Lu Jiao quickly said, "But she had a good life afterwards. She bumped into Li Juren's carriage, and Li Juren took her home for treatment. I adopted her, and although she is not as wealthy as the village lord in the Li family, her life is pretty good."

After listening to Lu Jiao's words, County Mistress Wen'an finally calmed down a little. She sobbed and asked Lu Jiao, "Then what did you say about the difficult labor last time?"

Lu Jiao said the matter of taking her son out of her abdomen earlier because she was annoyed that Duke Wu guessed that she had ulterior motives, so she said it out of anger.

Now hearing the county magistrate's question, I couldn't bear it, so I simply said: "She had a difficult labor at that time, so I performed an operation to cut her virginity."

Without waiting for the county chief to ask, he said, "Don't worry, the county chief, the surgery was successful and there were no problems. Don't worry, the county chief."

County Lord Wen'an knows that a woman's childbirth is a hell, but fortunately her daughter survived, but thank you Jiaojiao.

She was the benefactor of both mother and daughter.

County Magistrate Wen'an held Lu Jiao's hand and sincerely thanked him: "Jiaojiao, thank you, thank you for saving our mother and daughter."

Lu Jiao hurriedly stopped her: "The county lord should stop expressing thanks, maybe my sister is not your daughter, I sent you a letter to ask you to check and see if my sister is your daughter."
