Seeing that his cousin was so nice to him, Prince Rong of course drank the bowl of soup in front of him.

Afterwards, everyone at the table chatted for a while. Prince Rong, who had drunk the most soup, was the first to yawn.

Amid the sound of people chatting, he fell asleep leaning on the chair.

Yuan Chaokang was actually feeling sleepy too, having drunk quite a bit of soup, but he was relying on his instinct to keep himself going. Under the table, where no one else could see, Yuan Chaokang had pinched himself more than once.

After Sun Yuancheng, Zhou Yirong and Yuan Chaochang fell asleep one after another, Yuan Chaokang couldn't hold on any longer and fell asleep.

Before Yuan Chaokang fell asleep, he seemed to see his mother's relieved expression.

Knowing that it was his mother and father who were behind this, Yuan Chaokang felt relieved before falling asleep.

When Zhou Qiongyue and Yuan Bohua saw that everyone who should have fainted had done so, Zhou Qiongyue immediately ordered Doctor Zhao, the court physician, to come in.

After Doctor Zhao came in, he quickly made a small cut on everyone's arm with a dagger and dripped the things he had prepared in advance directly onto the wounds of several people.

Doctor Zhao waited until everyone's arms were dry, then he carefully applied the medicine.

The wound was very shallow and had been treated with medicine. If you didn't look carefully, you would definitely not notice it.

But this process is too simple and crude. There is no other way. Zhou Qiongyue was not a medical student in her previous life. The fact that she knew that cowpox could prevent smallpox was because she had read too many novels.

So Zhou Qiongyue had no good solution and could only let professionals do professional things.

When they woke up the next day, they all felt unwell, and Rong Ge'er was the first to have a fever.

Doctor Zhao, the court physician, carefully checked everyone's pulses and concluded, "They all contracted the same cold that the prince and princess had contracted."

Then Doctor Zhao suggested placing them in the same yard for easier care.

Of course Zhou Qiongyue readily agreed, and then Prince Rong and several children lived in the same yard.

The court doctor told everyone not to be exposed to the wind, so the five of them would just talk and chat in front of the windows in their respective courtyards when they had nothing to do, and it was very lively every day.

Prince Rong and his companions were indeed in much better health than Zhou Qiongyue and Yuan Bohua. Their symptoms were not as severe as theirs. Even if they had fever and acne, they were still full of energy.

Zhou Qiongyue even ordered the kitchen on the farm to prepare delicious food for them in different ways.

Among them, only Yuan Chaochang, Sun Yuancheng and Zhou Yirong firmly believed that they had caught a cold.

Prince Rong and Yuan Chaokang were both very clever, and they had their suspicions in their hearts. However, they both firmly believed that Zhou Qiongyue would not harm them. The court doctor said that they both had a cold, and that was what they both had.

Prince Rong felt something was wrong as soon as he woke up the next day. How could it be possible for him, a man who could stay awake for days and nights while fighting, to fall asleep while eating?

Later, seeing that Yuan Chaochang and the others also reacted, if he still didn't know who did it, he would have lived all these years in vain.

Finally, when he saw smallpox starting to break out on his body, he was not without fear, after all, he had heard of the symptoms of smallpox.

But when he saw how calm his cousin and brother-in-law were, he miraculously didn't panic at all.

After a few days, Prince Rong saw that he had recovered completely and thought he had overestimated it. If it was really smallpox, it would not be so easy to get over it.

Yuan Chaokang had some knowledge about smallpox in his previous life. A high-ranking concubine in his harem died of smallpox, and even he was terrified during that time.

Yuan Chaokang knew a lot about smallpox in his previous life, so he was very sure that he had smallpox.

He now suspected that the cold his father and mother had contracted earlier was also smallpox. He just didn't understand his mother's intention in doing this. Why didn't either of them panic?

Although Yuan Chaokang had countless questions, he did not panic. He was very confident that his mother would not harm them.

These few people are the ones that my mother cares about the most.

Under the careful care of the court doctor, Zhou Qiongyue and others, the few of them recovered completely after ten days.

Doctor Zhao, the court physician, was overwhelmed with emotion as he watched the recovered people. He felt that perhaps his story would be mentioned in future history books.

After everyone recovered, Zhou Qiongyue still sent news to the Princess's Mansion and the Marquis Cheng'en's Mansion.

Princess Yongchun received the news that her son had recovered from the cold and immediately put it aside. Her son would be fine with his friends.

As for why her friend didn't inform her from the beginning, Yongchun felt that her friend must have had a reason for doing so, and she still had some trust in him.

The prince consort was very worried and was scolded by Yongchun.

When Cheng from the Cheng'en Marquis' Mansion received the news, she was overjoyed. Now that her son had passed this hurdle, she and her husband would be much more relieved from now on.

If her sister-in-law were here, Cheng felt that she would kowtow to her.

Cheng looked at De Ge'er who was playing alone next to her, and felt sorry again that De Ge'er was too young and missed such a good thing.

After Prince Rong recovered, he was not in a hurry to leave. He stayed in the manor and played with the four boys.

Yuan Chaochang and his companions were a little uncomfortable when they first started hanging out with Prince Rong, but they had the foundation of living in the same courtyard together because of illness.

Soon everyone started playing together, except Yuan Chaokang.

Yuan Chaokang occasionally played with them, but most of the time he would find a place to read a book by himself, or follow Zhou Qiongyue and Yuan Bohua.

Yuan Chaokang actually wanted to ask about smallpox, but he felt that his father and mother must have their reasons for not telling him.

So Yuan Chaokang decided to read books on his own, and his interest in reading shifted from books on local customs and culture to medical books.

One day, Zhou Qiongyue saw the title of the book Yuan Chaokang was holding and wondered, "Kang'er wants to study medicine?"

Yuan Chaokang shook his head decisively, "I'm not really interested. It's just that my son has a question in his mind that he wants to know, so he looked it up in a medical book."

Yuan Chaokang was observing his mother's reaction openly while speaking.

Seeing her youngest son like this, Zhou Qiongyue knew what she didn't understand. Sometimes it's not good for a son to be too smart; it's hard to fool him.

Zhou Qiongyue looked around and saw that there was no one else around. The people serving them were also very far away. She pretended to be casual and said, "Is it possible that once a person has a disease, they will never get it again?"

Zhou Qiongyue blinked at Yuan Chaokang after she finished speaking, then ignored her son who was gaping in shock. "I'm going to find your father. You continue to look for answers!"

Yuan Chaokang didn't come back to his senses until his mother walked away, "Is that what I understood?"

Afterwards, Yuan Chaokang laughed, and his smile was a typical gloating. Judging from this, the mother didn't want to tell the emperor about this good news for the time being.

Yuan Chaokang knew very well what a great achievement this was for the emperor.

Yuan Chaokang thought that the emperor in the palace didn't know what he had missed, so he hummed a song happily.
