Menstruation, that is, big aunt.

This kind of human physiological problem that only exists in the history books, Gu Ruyun really never imagined that one day he would be troubled by it.

in the interstellar age.

This kind of physiological problem that plagues women has been completely solved in the early stage of genetic evolution.

In the evolutionary history of new humans, this kind of physiological problem disappeared almost two hundred years after the widespread popularization of genetic evolution.

At first, some people did feel strange, some doubted, and some felt uncomfortable, but after all this happened, other things did not change, and when women were still able to conceive and have children, everyone felt that after this physiological problem disappeared, life changed. more convenient and quicker.

So, when I was studying in school.

The matter of auntie was only mentioned in the history textbook. If it wasn't for Gu Ruyun's memory, she probably wouldn't remember the content marked in small print in the history book.

Gu Ruyun's face twisted involuntarily for a moment.

The original owner was an orphan, with poor food and clothing on weekdays. This body was already a little malnourished. In addition, he often went out to work and was very tired. Naturally, his body was not as good as other pampered girls. Age, the original owner has never had a menstrual period.

It is precisely because of Gu Ruyun's original inertial thinking, and the original owner has no memory of this aspect, that caused Gu Ruyun not to think about this aspect at all.

But now...

Gu Ruyun's face was pale and she covered her stomach. She really didn't expect such a small paragraph of text in the textbook to be so painful that she turned into such a cowardly look.

Wait until these two days are over...

"I must quickly develop a prescription that can make menstruation disappear, or make this guy less painful!"

Gu Ruyun cheered herself up in her heart. On the other hand, Aunt Liu had already come over with sanitary napkins. She took an unopened package and handed it to Gu Ruyun, asking her to go back to the bedroom and change it before coming out.

Yu Guang caught a glimpse of the little white cat lying on the desk in the room, sleeping quietly on the desk, and Aunt Liu breathed a sigh of relief.

It looks like...

She must be thinking too much.

only……

Wait a minute, will this doctor still call? Aunt Liu was a little confused.

...

After being poured down by a bucket of cold water, Gu Ruyun had lost his previous thoughts of training the cat, and went to the bathroom of his bedroom with a pale face. He followed the instructions on the packaging bag and dealt with his own affairs slowly. He went out of the room and went downstairs, feeling extremely bad.

Yangzi, who had been waiting in the living room for a long time, saw Gu Ruyun's pale face, watching him go downstairs with his stomach covered.

Friends of Women's skills instantly lit up, he blinked, and nodded suddenly.

Driving the car directly to the entrance of the hall, Yoko helped Gu Ruyun to open the car door with the help of a very gentleman.

Xiao Zhan pushed the wheelchair, watched the two drive away at the door, his eyes sank slightly, turned and pushed his wheelchair upstairs.

I don't know when his legs will stand up...

At that time, he will definitely be able to do something for Doctor Gu.

The car soon arrived at the gate of Qingliu University, Gu Ruyun was full of low air pressure, and got out of the car with dark clouds.

Every time she took a step, she felt as if she was stepping on the tip of a knife, her stomach hurt and her legs were trembling, but she still had to come to school, really...

Oh life!
