Cai naturally agreed with Lin Wan's approach, and Lin Na learned that Lin Wenbo had moved directly into Qingyunju, she was as quiet as a chicken and dared not make trouble again.

Because of the chaotic situation yesterday, Lin Wan had only time to self-enclose Qingyunju, and had not had time to do and ask and implement the root cause.

Since Lin Wenbo has entered Qingyunju, this matter is left to Lin Wenbo.

Lin Wenbo tossed and turned last night and couldn't close his eyes all night. At the beginning, he thought about the safety of his daughters most. After calming down, he made a constitution in his mind.

Although it is relatively common for young children to suffer from chickenpox, both himself and his eldest son Lin Hongfei had suffered from chickenpox.

However, no infectious disease is groundless and must have root causes.

For example, his own chickenpox was caused by the sickness caused by the person who was serving him when he went out to contact chickenpox patients.

Lin Hongfei's chickenpox was caused by Luo's inadvertent contact with a child with chickenpox when he took him to a plum blossom banquet.

So where did Lin Yuan’s chickenpox come from? Who have been in contact with Lin Yuan in the past two days?

Only by finding the root cause can we cut off the transmission route to prevent the spread of chickenpox.

After visiting Lin Yuan, he confirmed that Lin Na and Lin Wan are both healthy for the time being. Without Lin Wan's reminder, Lin Wenbo began to trace the source of the virus.

Lin Yuan continued to take care of Lin Yuan.

Thinking of the possible transmission route, Lin Wan thought about it and sent someone a letter to Cai.

Cai's reply made Lin Wan feel relieved.

Cai and Tang had seen big scenes. Although they had not had time to trace the root cause, after the doctor of the government confirmed that Lin Yuan had chickenpox, they immediately sent letters to several places, including the places where Cai had been yesterday.

Lin Wenbo was a magistrate and soon found the possible root cause.

However, to implement this root cause, it still needs to be verified by the Imperial Medical Department's Epidemic Prevention Department.

"The root of the wet nurse is really the wet nurse?" Lin Wan's brows were slightly moved. In fact, she also had some doubts about the wet nurse.

Yesterday, Lin Yuan was already in a serious fever, but the wet nurse only used a cold veil to cool down Lin Yuan physically, and she didn't even invite a doctor in the government, which was extremely abnormal.

It is said that Lin Yuan's wet nurse was a young wife from a branch of the Lin clan. The man had always been in poor health and died just one year after getting married. The wet nurse was pregnant at the time, but unfortunately the child she gave birth to was stillbirth. She was regarded as a husband and son. The old lady who had lost her son and grandson drove her out of the house.

She had met Luo twice and was quite good at speaking, so she asked him to Luo.

Luo pity her for being alone, so he took her in to do some miscellaneous work. It was a coincidence that Lin Yuan refused to eat the milk of the original wet nurse, so he asked her to try to feed Lin Yuan. After a while, he became Lin Yuan's wet nurse.

After Lin Wan went to the academy the day before yesterday, the wet nurse received a letter and soon went to ask An Huijuan for leave, saying that the good sisters from Jizhou had come to the capital and wanted to go out to meet her.

Zhennan Hou’s Mansion has never been so strict with his servants. An Huijuan is not a harsh person. Since he was from his hometown, he had to let the wet nurse arrange the people who were waiting around Lin Yuan when she went out.

The wet nurse stayed outside for a whole day until Lin Wan took Lin Yuan to go back to Qingyunju after dinner with Cai from Ci'anyuan to get back to Qingyunju.

Because Lin Wan is still young, since Lin Wan started studying in the academy, Cai did not allow Lin Yuan to go to Ci'an Garden to pay good morning.

Every day, Lin Wan would go to see Lin Yuan before going to Ci'anyuan to pay her respects. Yesterday, because she got up a little late, Lin Wan hurried to Ci'anyuan after packing up.

The wet nurse kept taking Lin Yuan in the house this day, and even the people from Qingyunju never saw Lin Yuan go out. It was not until Lin Wan came back from the academy that she found Lin Yuan had a high fever!

"Who did you ask who was the one whom you met the day before yesterday?" Lin Wan grabbed Lin Yuan's little hand that was about to scratch her face and asked calmly.

The reply was Madam Bai. Today, she was the one who cooperated with Lin Wenbo to trace the root of the source: "It was her mother's sister."

My mother's sister? Just came from Jizhou?

Madam Bai saw the doubts in Lin Wan's eyes, and then answered the questions she asked about the wet nurse one by one.

It turned out that the wet nurse's sister had already entered Beijing with the men from the business in July. She had some contacts before, but the contacts between the sisters were not frequent, and she had never even met each other before.

The day before yesterday, the wet nurse's sister sent a letter and told Jizhou that someone was coming again and asked her to go out to meet her.

The wet nurse thought about not being able to defeat the family affection again and again, so she took a leave and went out.

But this trip made the wet nurse very scared.

The place where the wet nurse's sister rented was far away from Zhennan Hou's Mansion, so it was impossible for the wet nurse to arrange a carriage from the mansion. She called a carriage outside.

The wet nurse got off the carriage and saw a slum-like place. She almost turned around and wanted to leave. But as soon as she got off the car, an old lady guarding the entrance of the alley came up to her.

The old lady was the wet nurse's sister's nanny. The wet nurse had to bite the bullet and follow the old lady into the extremely narrow alleys with sewage and extremely narrow.

When she entered the rented yard, the regret in her heart surged like a tide, but it was too late to leave at this time, so she had to patiently deal with it.

There was something even more unexpected to her later. There was actually a child with a high fever at her sister's house!

When the wet nurse glanced at the rash on the child's neck, she was so scared that she stepped back and complained repeatedly, and she knew even more that she shouldn't have come today!

Although I was not sure what patient the child was giving birth to, Lin Yuan was relatively weak. Even if she was just an ordinary wind and cold and fever, if she returned with sickness, she would be at risk of being infected with sickness.

The wet nurse did not stay at her sister's house for a long time. She took out all the money she had with her, and took the child to see a doctor quickly, so she took the opportunity of others sharing the money and took off.

Because of some suspicion, the wet nurse was anxious, angry, but lucky. After wandering outside for a long time, she finally returned to Zhennan Marquis' Mansion. She took a bath before Lin Wan took Lin Yuan back from Ci'an Yuan and dealt with all the coats, shoes and socks she wore when she went out.

Unfortunately, things did not develop as she wished. Lin Yuan had a fever that day and night. Even though the wet nurse was so lucky, she tried 100% to cool down Lin Yuan, Lin Yuan's fever was getting higher and higher, and she was eventually diagnosed with chickenpox.

After finding the most likely root cause, the Imperial Medical Department's Epidemic Prevention Department had a target of blocking infection. Soon the alley rented by the wet nurse's sister was closed. After thorough investigation, except for the wet nurse's sister's courtyard, there were at least three chickenpox patients in this alley. Because of the report and timely pursuit of the source, the chickenpox epidemic in the capital was effectively controlled. The Zhennan Hou Mansion was not damaged by the chickenpox epidemic, but was commended by the emperor.
