After reading the memorial, the emperor calmed down considerably and handed it to the eunuch, indicating that he should show it to the Grand Princess.

The Grand Princess was even angrier after reading it.

Xie Tingzhou recounted in his memorial that the old lady, in order to seize control of the family, ordered Granny Chun to use a diseased handkerchief to harm people.

The grandmother's framing of her granddaughter-in-law was a family disgrace. To save face for the old lady, and because she insisted that it was a common smallpox, Ye Zhen temporarily sealed off the mansion and instructed Fu Guang to write to Xie Tingzhou in time.

Xie Tingzhou also felt that the old lady would not be so vicious as to want to wipe out the entire Marquis's family, so he told Ye Zhen to wait for him to return before making any decisions.

During this period, the imperial physician diagnosed him with smallpox. Ye Zhen happened to know how to prevent smallpox and wanted to take the opportunity to test it on himself. If he succeeded, he would present the method to the imperial court.

Xie Tingzhou was very interested in the preventative technique, as it would provide an extra layer of protection for Dayuan. Therefore, he gave Ye Zhen time, intending to report the matter after Ye Zhen succeeded.

On his way to Beijing, he received good news from Ye Zhen.

In other words, Ye Zhen was only following her brother-in-law's orders. A woman is respected by her husband, and when her husband dies, she is respected by his family. Now, only the Marquis of Zhongyong and his son remain in the Marquis's mansion, and the Marquis of Zhongyong is far away in the northwest. Ye Zhen can only listen to Xie Tingzhou.

She was not unfilial; instead, she protected the reputation of the Marquis's mansion after the old lady made a mistake, waiting for Xie Tingzhou or the Marquis of Zhongyong to return to the capital to deal with it.

She was not unfaithful; despite the danger of smallpox, she personally inoculated herself, just to present the treatment to the court.

The Grand Princess couldn't find fault with her, but once a person harbors resentment and is determined to kill someone, the more obstacles they encounter, the more unwilling they become, and they also hate those who ruin their plans.

"As an official appointed by the imperial court, Xie Tingzhou should have been well aware of the harm smallpox could cause to a country, yet he condoned Ye Zhen's actions..."

“Grandmother, if the smallpox inoculation method works, it will be a great achievement.”

The emperor interrupted the eldest princess.

For a country, if it can obtain smallpox prevention techniques, then Ye Zhen and Xie Tingzhou's little bit of concealment is nothing.

He not only cannot punish, but must also reward.

Ye Wantang's eyes darted around; she had been searching for the manuscript for the past few days without success.

Hearing the emperor mention smallpox inoculation reminded her that Ye Jinghong had also mentioned it.

How did she do it again? She tried hard to remember.

It seemed like cutting open a person's hand and squeezing the patient's pus into the wound to infect them, but she couldn't quite remember why she wanted to infect them, though the method should have been like that.

Yes, that should be it.

Having made up her mind, she volunteered, "Your Majesty, I heard my mother mention smallpox vaccination when I was young. I am willing to share Your Majesty's burden and go to the East Market to get vaccinated."

What Ye Zhen can do, she can do too; she absolutely cannot let Ye Zhen get all the credit.

As for the method, she couldn't quite remember it right now, but she was confident that it would work if she experimented on a few more people.
