Time flies, and it's the second week of June. In the domain of Baron Walton I of Yorkshire, a parochial school of stone and wood was erected with a slate roof, smoke vents, a fireplace (only the wealthy families of the country such as joman or a gentleman would have a smoke vent and a fireplace), partitions, floors and glass windows.

The mission school was named St. Michael's Church School and had two halls for 100 people, two teachers' rooms for priests and priests to rest and eat, a kitchen, and a small school to the south of the school. In addition, the school's patron, Miss Isabel, the daughter of Baron Walton, provided the school with hundreds of additional sets of tables and chairs, kitchen utensils and cutlery, as well as the use of arrows, longbows and arrows for the practice of archery (archery was compulsory since Edward I). Of course, due to the additional expenses, Miss Isabel invested another £10 in the construction of the school.

Since the school provides free basic education, it is open to children aged 6 to 18 from poor families in the Barony of Walton. The baron's daughter originally conceived the idea of providing education for the children of the villagers who were struggling to make ends meet. However, as soon as the school was established, it immediately caused a stir among the villagers in the territory and several nearby villages. If nothing else, this free church school has the size and furnishings that only wealthy rural families have.

While poor rural families sent their sons and daughters to school, several newly wealthy farmers in the barony's lands began to be anxious about their children's education. After some discussion, the families unanimously decided to let Richard Tyxton, as the representative of the wealthy families in the realm, negotiate with the lord's daughter to allow their children to attend school.

On the other hand, Rev. Roger Eslip, resident pastor of the Territory Church, found a small vacant lot north of the village of Kirklington. Located in a small area of primeval forest to the north, this clearing is a fresh and elegant environment, surrounded by no farmers other than a large area of cultivated land, which is suitable for building a hall for isolation and treatment of the plague. So, when the church school to the south was opened, a medical hall was quietly set up hidden in the forest to the north.

The 20 squires sent by Isabel to secure the territory had finally brought back good news, two squires had found a female villager suffering from cowpox in the sparsely populated Yorkshire Highlands. After the attendants brought the female villager back to the lord's domain, Isabel immediately had the female villager placed in the medical hall.

In the eyes of the subjects or servants of the territory, the female villager who suffers from cowpox is a sin-possessed secular woman, and no one dares to approach her or touch her. In desperation, Isabel could only go into battle to extract some cowpox liquid from the cowpox on the female villagers. However, she had a big problem with the tools to extract the liquid – there were no needles and needles. Without these two medical devices, she felt that she would not be able to safely extract the valuable liquid that fights the smallpox virus.

Other than that, even if the liquid can be obtained, there doesn't seem to be a suitable container to keep it. In addition, she needed a volunteer to vaccinate the vaccinia fluid. On June 6, the afternoon of the first fasting day of June, Isabel made a bold and astonishing decision after returning from the Duke of Richmond's castle with several saber guards.

Baron Walton staggered up from behind his desk when he heard her decision. He frowned and glanced at the two maids standing not far behind his daughter, then at the personal servant beside him, and ordered in a low voice, "All servants leave the study at once." ”

When only the Baron and his daughter were left in the business room and study, the Baron paced his daughter with his hands behind his back. After a long while, he raised his head and looked at his daughter, "Daughter, why did you take the initiative to bring the plague to yourself??" Do you want me and your mother to lose our daughter again? ”

Among the decisions Isabel made was to volunteer herself with vaccinia liquid. The purpose of volunteering is that a single vaccinia vaccination can only provide immunity for about 6 years, so it is necessary to have regular vaccinations to prevent smallpox. The last time she was vaccinated against vaccinia was 10 years ago, so she had to get herself vaccinated again against smallpox.

Of course, these were matters that Baron Walton could never understand, and she was reluctant to go through the trouble of explaining the cowpox inoculation that would only occur in England at the end of the 18th century. Isabel looked at the baron calmly, and smiled softly as she pondered her words, "Father, this is what my maid Dorothy saw and heard with her own eyes. In any case, the female hired woman in the village where she used to live was later cured. ”

With a gloomy face, Baron Walton walked over to the cupboard on the side of the study and poured himself a glass of wine. Turning and standing in front of the cupboard, he looked at his daughter in thought, "Can this maid swear to God, and what she sees and hears is the truth?" ”

"Of course. If she lied to me, why would she stay in the manor and be my maid? ”

"Well, let the priest and the maid go to the hall, I need her to take a solemn oath in front of the priest."

Isabel nodded and walked over to the desk, leaning her hips lightly against the edge of the desk and then said something else to the baron, "Father, my sister's husband, Sir Herbert, has been in Aske Manor for three weeks, and today I am going to check on Sir Herbert. ”

Baron Walton sighed deeply, looked up at the ceiling and said, "My family and I sincerely repent and pray to God, will God still bring sin upon me and my children?" ”

"Father, the plague in Sir Herbert's body can be cured. It's just that my brother Ernest hasn't heard from me yet, and I'm worried that he will be on the battlefield in Scotland...... "Isabel has a premonition of something very bad, but she still hasn't said the worst possible thing.

Baron Walton walked to the window on the left side of the cupboard and opened it to look at the trees, flowers, school yards and stone walls behind the manor, "Daughter, this is the mission that God has given to Ernest, to declare war on evil bravely and fearlessly. Only by paying with his blood and life in the fight against injustice and evil can he be worthy of the honorary title of knight. ”

It seems that Baron Walton was mentally prepared for the death of his heir, Sir Ernest Walton. Isabel didn't say anything more, just nodded slightly, "Father, I know, I'll have the priest and maid fetched at once." ”
