After being reborn, my sister insisted on marrying me.

In mid-January, Beijing enjoyed several rare days of consecutive sunny weather.

Chen Xinyi's second prenatal checkup was scheduled for that morning.

Wei Yi accompanied her.

It was still Peking Union Medical College Hospital, and still Zhang Kexin's large consultation room.

Zhang Kexin held the ultrasound probe and gently slid it across her lower abdomen.

This task was originally the responsibility of doctors in the examination department.

But human relationships are something that exist everywhere.

Top-tier hospitals like Peking Union Medical College Hospital are even more outrageous.

Especially doctors of Zhang Kexin's caliber.

She has two consultation rooms.

One is a typical small clinic, about ten square meters, used for daily work.

The other is a huge consultation room used to receive special patients.

The large consultation room only contained space-consuming diagnostic equipment such as CT scanners.

Almost all of them have those that don't take up much space!

Now she is in her own large consultation room, receiving her future sister-in-law and husband.

On the ultrasound monitor, two small gestational sacs were clearly visible.

two.

Zhang Kexin pushed up her glasses, looked at it carefully several times, and then turned her head, saying in a professional yet excited tone, "Sister, you're also having twins."

She can now call out "sister" very naturally.

Instead of the joy they felt when they called each other friends.

There was a two-second silence in the examination room.

Wei Yi was the first to react, his voice filled with surprise: "Twins too?!"

"Yes. Two gestational sacs, measuring 1.2 and 1.1 centimeters respectively. Both are developing very well."

Chen Xinyi lay on the examination bed, stunned at first, then slowly grinned and smiled.

"Siyan is pregnant with twins, and so am I having twins too?"

"Yes," Zhang Kexin smiled as well. "Did you two plan this?"

Chen Xinyi smiled so hard her eyes crinkled: "No appointment. It's just...fate."

She turned to look at Wei Yi, her peach blossom eyes shining brightly: "Brother, did you hear that? Your sister is also a twin. Two of us. Just as many as Si Yan."

Wei Yi stood beside the examination bed, his expression a mixture of surprise and delight.

The element of surprise was clearly greater than the element of joy.

He remembers it perfectly clearly.

In his past life, Chen Xinyi gave birth to four children for him.

All four pregnancies were single births.

There are no twins.

Lin Siyan only gave birth once in her previous life, and then she got her tubes tied.

But in this life, Lin Siyan's first child was twins.

This was already surprising enough for him.

Now Chen Xinyi has also brought a pair of twins.

The problem is that she doesn't know if Lin Siyan's ancestors had a history of twins.

But when he thought about it carefully, he realized that his sister and the Chen family did not have the genes for twins.

Then... this can't be explained by a simple "accident".

Wei Yi stared at the two small dark shadows on the ultrasound screen, his mind racing.

Could it be... because of my rebirth?

Is it still that same internal martial arts style?

In his previous life, he only practiced boxing for a month before he felt completely refreshed.

If it weren't for the favorable winds and waves, and the desire to take on ten at once, but instead to develop slowly...

Perhaps I won't even need to be reborn.

He started training from the very first day of his rebirth.

After practicing until now, the energy in my dantian...

It's no longer just "heat" anymore.

Could it be that set of boxing techniques?

Can even this really change?

Or perhaps, having been reborn, his genes have been upgraded?

Wei Yi couldn't understand it.

But there was one thing he was 100% sure of.

This is a good thing.

This is fantastic news.

"Brother, what's wrong with you?" Chen Xinyi sat up on the examination bed and waved her hand in front of his eyes. "Are you so happy you've gone crazy?"

After saying that, she glanced at Zhang Kexin, who was smiling broadly beside her, and immediately added, "Even if you can be the uncle of two children at once, you don't need to be this happy, do you?"

Wei Yi snapped out of his daze and realized that his older sister was reminding him that the white deer was still there.

Wei Yi had no choice but to cooperate, smiling as he held her hand: "Sister, I was thinking that your family will need to hire more nannies in the future to take care of so many children."

Chen Xinyi laughed out loud: "This is nothing. Only four. Later there will be Sister Shilin's, Sister Wu's, Xue Li's, Momo's, Tongtong's..."

She laughed halfway through her count.

Zhang Kexin, who was standing next to her, was practically dumbfounded.

What... what's going on here?

Then, the notorious Chen Xinyi looked at her with a smile, "Sister Kexin, you won't go around saying things like that, will you? Um, the people I just mentioned are all my boyfriend's wives."

"It's all...it's all..." Zhang Kexin's beautiful eyes widened slightly.

"Yes." Chen Xinyi smiled, pointed to herself, and then to Wei Yi, "My husband, my boyfriend, who is also Wei Yi's brother-in-law. He has many, many girlfriends, and all of them are very willing to have children for him."

Zhang Kexin: "!!!"

Although he is one of the best obstetricians and gynecologists in the country.

Zhang Kexin also came into contact with many families with complicated internal family situations.

But... she is still young after all.

I've only been working for a few years; the first twenty-odd years were mainly spent studying.

This was the first time she had ever heard of such a complicated situation as Chen Xinyi described.

Moreover, it was mainly related to her lover. After the initial shock, she couldn't help but look at Wei Yi.

I thought to myself, "My poor husband, your sister is so pitiful, having to compete with so many women for her husband..."

Wei Yi also noticed the slightly pitying look in Zhang Jie's eyes and the malicious smile on her lips.

He sighed inwardly.

This wicked man is teasing the white deer again.

"Sister, we can talk about brother-in-law's matter later."

He had no choice but to say, then helped her out of bed, carefully, as if holding a rare treasure, "Let's go back first. There are still dozens of people waiting in line behind Kexin."

"Okay." Chen Xinyi nodded with a smile, and stopped teasing the white deer. "Then I'll go out first. You two can chat."

Zhang Kexin, who was still in shock and lost in thought, immediately came back to her senses upon hearing what she said.

She blushed slightly.

Because he heard his sister admit that she and he were a "young couple".

This made Dr. Zhang very happy.

but……

After Chen Xinyi left.

"Wei Yi," Zhang Kexin couldn't help but whisper, "Does your sister and Siyan's boyfriend have some kind of special formula? Or some twin gene? How come both of his girlfriends are pregnant with twins? Could it be that his other girlfriends are also pregnant with twins?"

She asked the question with a serious expression, her big, bright eyes brimming with curiosity.

After all, if this were true, it would be a huge help to her academic career.

Wei Yi's lips twitched.

"Well... I'm not really sure either. Maybe... it's just a coincidence."

"A coincidence?" Zhang Kexin frowned. "Do you know what the probability of naturally conceiving twins is? It's about one in eighty-nine. The probability of two mothers carrying twins with the same father is... let me calculate..."

She actually started calculating in her head.

Wei Yi quickly changed the subject: "Sister Kexin, did you get off work early today? How about we have dinner together tonight?"

"Oh? Oh, I'm on the day shift today, I can leave at 5:30." Zhang Kexin's attention was indeed diverted. "But your sister just finished her checkup, do you want to take her home first?"

"It's alright," Wei Yi said with a smile. "It's only morning. I'll take her home and pick you up later this afternoon."

"Uh-huh."

Zhang Kexin saw off her siblings with a mix of joy and deep shock.

She was just about to return to her small clinic to continue seeing regular patients.

But as soon as she reached the door of her small clinic, she felt a slight pain in her lower abdomen.

This feeling was fleeting.

If it were an ordinary person...

I would absolutely not care about this level of pain.

Because it really only lasts for a moment.

But she is Zhang Kexin, and she has a little secret.

So this outstanding young woman from the Department of Obstetrics and Gynecology at Peking Union Medical College Hospital immediately turned around and abandoned the patients who were queuing up.

She returned to her large consultation room and drew blood from herself.

the other side.

On the way home, Chen Xinyi leaned against Wei Yi and whispered, "Brother, why do you think Siyan and I are both pregnant with twins?"

Wei Yi put his arm around her shoulder and remained silent for a moment.

"Maybe... I'm just too healthy?"

Chen Xinyi looked up at him: "You're healthy, how could that affect how many babies we can have? Although I'm not a medical student, I have taken biology classes. Twins are generally related to the woman's genes. I don't know about Siyan's side, and I've never heard of anyone in our family having twins."

"That's probability, I guess," Wei Yi said. "Maybe God likes me and secretly increased my chances of having twins?"

Although Chen Xinyi still didn't believe it, it was indeed a good thing.

"May the master protect us!"

She then smiled and recited one of her mother's favorite slogans in Chaoshan dialect.

Then he added, "Who cares? As long as they're your children, I'll have as many as I want."

Wei Yi lowered his head and kissed the top of her head.
