The eldest sister was reborn and the younger sister traveled through time. I just want to survive.

Before the maid finished speaking, Yan Muxi stood up hastily, "Mother was fine last night, how come she suddenly felt unwell?"

"Please don't worry too much, Princess. The princess is fine, but she occasionally suffers from palpitations and shortness of breath. The symptoms were more severe this morning, so we sent someone to invite Madam Gu Jiu to come over." The maid explained.

"I hope mother is fine. Since my third sister has come to the palace, I will go over to take a look."

When she arrived at Zhuxiang Hall, Yan Muxi realized that Minghui had also come to the palace. She didn't bother to exchange pleasantries with Yan Muyun and Minghui. She looked at Princess Rong first, and was completely relieved when she saw that her face was rosy.

"Mother is not feeling well, why didn't you send someone to tell your daughter-in-law? Is your son feeling better now?"

"Don't worry, my shortness of breath and panic are old problems, it's nothing serious. I invited your third sister to come over today because I wanted you sisters to meet her and have someone check on you." The princess pulled Yan Muxi to sit beside her, not forgetting to take care of Yan Muyun and Minghui, "Don't be restrained, both of you, sit down and talk!"

Yan Muxi realized that Princess Rong's invitation to Yan Muyun to come to her house to treat her illness was fake, and her real intention was to treat her.

Jin Chun, the court physician, and the imperial physician all said that there was nothing wrong with her body, but Princess Rong still specially invited Yan Muyun, who was in mourning at home, to come to her home.

She couldn't figure out for a moment whether Princess Rong was concerned about her health or was afraid that she was in poor health and could not give birth to an heir for the palace.

After chatting for a while, Yan Muyun took Yan Muxi's pulse.

"Second sister is in good health, but her growth and development period is a little later than that of her peers, which will not affect her ability to conceive." Yan Muyun glanced at the gentle-looking Princess Rong and considered her words before speaking out, "Although second sister is not young anymore, she has just had her first period and her body is not fully developed yet. It would be better if she waits two years before conceiving a child."

The meaning is very clear. Yan Muxi's body is not yet able to conceive a child, and it is not even suitable for her to have sex with her husband too early.

The next year, Prince Rong would be twenty-one years old, old enough to be a father. He was also the only son of the royal family, so it was not realistic to let the Rong Palace wait for two years in vain.

As a modern soul, Yan Muyun is temporarily unable to accept that Gu Yunting and she have illegitimate sons and daughters. Fortunately, the second brother has the thinking of an ancient person. If Prince Rong really has illegitimate children, he should be able to accept it.

Moreover, she felt that the second son was an open-minded and transparent person. Between health and honor, he would definitely choose the former, so she told him her concerns directly.

Yan Muxi was shocked for only a moment, but she soon understood. The doctor who had examined her pulse had not told her that she was not suitable for bearing children, and even Jin Chun had not mentioned it to her.

Because everyone understood that it was impossible for the Rong Palace to wait until she grew up before having children. It would have the same result whether this matter was mentioned or not. If it was mentioned, it would make her feel uneasy.

Princess Rong should have been shocked, but her expression and tone were calm. "Since you are weak, just take care of it for two more years. It's not a big deal. Madam Gu Jiu finally came to visit us, so she must stay for lunch before leaving. It just so happens that you two sisters haven't seen each other for a long time, so you can talk about personal matters."

Regardless of whether her consideration was genuine or fake, Yan Muxi's heart was warm.

As a mother-in-law, it was commendable that Princess Rong could maintain her dignity after learning that her newly married daughter-in-law was unable to bear children in a short period of time.

It was inconvenient to talk in the princess's courtyard, so Yan Muxi took Yan Muyun and Minghui to the lake.

There was no one around, so Yan Muxi asked Yan Muyun directly, "Did your third sister have her period?"

Yan Mujun was a whole year younger than her and had been married half a year earlier than her. They were sisters, so it didn't make sense that she was the only one with delayed menstruation.

"I have had my period for more than two years, and my body must be fully developed. Although it is a little early to have a child, but having sex..." Facing two pairs of wide-open eyes, Yan Muyun swallowed back the words that were too explicit.

She is a modern soul and a doctor herself. She feels no shame in talking about private topics, but she forgets that this is ancient times. If she doesn't feel ashamed, others will feel ashamed too.

"What is period? Is it related to menstruation?" Yan Muxi asked curiously.

"A period is just your period. It sounds better than saying it bluntly."

Yan Muxi nodded in agreement with Yan Muyun's words, "This euphemistic way of mentioning it does reduce some of the embarrassment that is hard to talk about. In addition, there is one thing I don't understand. We are all sisters. The eldest sister and the third sister both had their periods before they came of age. Why did I come several years later?"

"There are genetic and personal reasons for early or late physical development, and it is difficult to determine the specific reasons. In short, everyone's growth and development are different. Some develop early and grow early, while others develop late and grow late. In short, no matter whether it is early or late, as long as it is within a reasonable range, it will not have much impact on physical health."

In ancient times when there were no advanced instruments to detect bone age development, Yan Muyun could only try her best to popularize science.

"In fact, it may not be due to one's own condition or genetics." Minghui suddenly spoke up to refute Yan Muyun's judgment.

Upon hearing this, the two sisters looked at Minghui. Minghui looked up at the sky and fell silent again.

Yan Muxi said angrily, "Ah, Aunt Ming, just tell me what you know. Are you going to wait until I'm expelled from the palace before you tell me the reason?"

Minghui glanced at Yan Muyun, and Yan Muxi understood instantly that some things were not easy to say in front of Yan Muyun, and the things that even her family had to hide could only be related to her experience of being kidnapped as a child.

Even though they were sisters with a good relationship, she couldn't easily reveal the fact that she was kidnapped to Yan Muyun, so she could only change the subject.

"I heard that third sister also has a mole on her arm. Is it the same as mine?" After saying that, he rolled up the sleeve of his left arm.

"You also have a mole on your arm. I have one too, but the color is different. Mine is red." Yan Mujun said as he rolled up the sleeve of his left arm. The blood-red mole on his fair arm was particularly eye-catching.

Yan Muxi thought that the red moles of the three sisters would change color with age, but it turned out that it was not the case. Only hers changed color.

"Has the mole on Third Sister's arm always been this color? Is there any sign of it getting lighter?"

"It hasn't gotten lighter. It seems to have gotten bigger and redder as I've gotten older!"

"My mole was also red when I was young, but it changed color when I grew up. Ninth sister also has a red mole on her arm. I wonder if hers will change color?"

Upon hearing that the newly adopted ninth young lady in the mansion also had the same red mole, Yan Muyun could not hide her surprise.

According to genetic genetics, children may inherit the genes for moles from their parents, but if multiple children inherit the same mole position, it would be too coincidental.

The two sisters were excitedly discussing the red mole on their arms, and didn't notice Minghui, who looked even more shocked than them.

Soon, the maid from the princess's courtyard came to invite them to go back for lunch.

After all, he was still in mourning, so Yan Muyun said goodbye after the meal. Yan Muxi didn't get a chance to be alone with Minghui, so the doubts in his heart could only be resolved when they met next time.

But she didn't expect that Minghui left Luodu and returned to Jiangnan on the third day after coming to the palace, without even saying goodbye to her.

He only left a letter with a few words, telling her not to worry about her body, that late menstruation was a good thing, and that her gluttony and sleepiness would gradually ease.

He also specifically told her to live her own life well, not to worry too much, and not to meddle in matters that should not be her business.
