The envoys from the Dongchu were indeed very familiar with the situation on the road. Along the way, they didn't stop at all, and in less than half a month, they had already arrived at the Xiqin Kingdom's borders in the east.

As the sky darkened, the group of people settled down at the relay station.

"Prince Xian, we still have a day's journey before we reach Fringe City." Throughout the journey, the Princess Chuchu had repeatedly expressed goodwill to Mu Yuntian, but Mu Yuntian's expression had always been indifferent.

"Yes." This King knows. Princess, rest early. We still have to hurry back tomorrow.

Mu Yuntian turned and left.

Bai Su looked at Princess Chuchu who stretched out a hand wanting to stop Mu Yuntian, but didn't know why she should call him that. She couldn't help but to curl the corner of her mouth.

Mu Yuntian really did not know how to show mercy to a beauty.

However, she liked it.

Early the next morning.

Bai Su had just woken up and was standing in the courtyard.

Seeing the people coming and going, he couldn't help but hold a servant girl and ask, "What happened?"

The servant girl replied, "Princess Chuchu suddenly suffered from an illness, even the imperial doctors accompanying her were helpless …"

Bai Su's expression changed slightly. "Let's go, I'll go take a look."

When he was heading to Chuchu's room, he coincidentally bumped into Mu Yuntian.

The two of them explained the reason and were able to enter.

"Scram!" All of you, scram out of this princess' room! " It was rare for the gentle Chuchu to lose her temper like this.

Bai Su and Mu Yuntian looked at each other, and immediately understood.

Since even the patients refused to cooperate, it was no wonder that the imperial physicians were helpless against them.

From a distance, Bai Su looked at Chuchu, her pupils contracting.

She said to Mu Yuntian: "Let them all go out first, I have a way to get her to cooperate."

Mu Yuntian nodded his head, and then spoke a few words to the imperial physician and her servant, causing everyone to follow her out.

Only Bai Su and Chuchu who was huddled up in a corner remained in the room.

Bai Su lifted her feet and walked over to the bedside.

"Scram!" Get lost! " When Chuchu heard the noise, she grabbed a pillow and threw it over.

Bai Su grabbed the pillow, she did not listen to Chuchu's words, but continued to walk towards the bedside.

Chuchu raised her head and saw Bai Su. She could not help but say in surprise, "It's you?"

During this time, Bai Su had always been inseparable from Mu Yuntian, so Chuchu naturally had a deep impression of him.

"What are you doing in this princess' room? "Get out." Her eyes were red, and she sounded a bit irritable. She was not as gentle as she usually was.

Bai Su was not angry, she walked over to the bed and placed the pillow on top of her bed.

He did not speak immediately, but stood by the bed, staring at her.

Chuchu's face was pale. She was curled up with one hand against her belly and the other holding her clothes. She looked like she was suffering from the pain.

Bai Su understood and sat on the side of the bed. She extended his hand to Chuchu and said: "This is the first time right? Does it hurt? Hold out your hand and I'll take your pulse. "

Her voice was not very gentle, but it was not very cold either.

She raised her head and looked at Bai Su, her pale face looked a little embarrassed.

"How do you know?" Chuchu's body trembled as she stared at Bai Su, "You're a doctor too?"

All along the way, her attention had basically been on Mu Yuntian; she simply did not spare any attention to observe anyone else.

"Yes, I'm a doctor. Give me your hand. " Bai Su said.

Chuchu hesitated.

As if he had thought of something, he suddenly raised his head and hissed: "Get out! Get out for this princess! "

Bai Su frowned.

After some thought, she suddenly stretched out her hand to untie the belt on her head that had a ponytail tied to it.

Immediately, a head of jet-black hair drooped down.

At first, Chuchu was surprised by her actions. However, when her hair was let down, her mouth was opened so wide that she could not complete her sentence, "You … "You are … a woman?"

"Yes." Bai Su smiled lightly, "Does Princess Chuchu still feel that it is inconvenient?"

Chuchu didn't say anything. She only hesitated for a while before she reached out her hand.

Bai Su smiled and reached out to her veins.

"Who are you? Why are you pretending to be a man? " Chuchu could not help but ask curiously, "Why are you following beside the Prince Xian?"

Bai Su lifted her head and looked at her, "Princess Chuchu, please do not speak for the time being, it will affect my diagnosis and treatment."

"Oh." Although Chuchu closed her mouth, her eyes were still filled with curiosity. She stared at Bai Su without blinking.

After checking up on Chuchu, Bai Su calmly wrote out a prescription as she said, "Your initial tides have come even later than the average girl, so you will feel extremely uncomfortable. However, this is something that happens to every girl as she matures, and you don't have to feel embarrassed about it. "I'll give you a prescription right now. You just need to take the prescription every month and heal yourself for half a year. In the future, you won't have to suffer so much pain every month anymore."

Bai Su wrote the prescription, while tying up her hair with a ribbon, she said to Chuchu: "Call your servant girl in."

Chuchu endured the pain and called out to the door.

After the servant entered, Bai Su passed the medicinal formula to the servant girl: "Use the medicinal formula to boil the medicine, and feed it to the princess three times a day for her to drink. "In addition, prepare a stove. Do not make it too hot, let the princess place it in her abdomen."

Chuchu was at least fifteen years old this year. She had only gotten her period for the first time, so it was rather late.

Some people feel pain for the first time, and then every month.

However, it wasn't impossible to treat dysmenorrhea. Of course, one round of treatment was useless. He would have to take his time to recuperate.

It was only after Bai Su left did Chuchu remember that she had not asked him clearly why she was disguised as a man to follow beside Mu Yuntian. What was their relationship?

Originally, she did not have a special impression of Bai Su, but now that she was a girl, Chuchu's heart was not at ease.

This was because on the way here, she had clearly seen how close Mu Yuntian and Bai Su were.

He had always thought that Bai Su was a man and felt that no matter how close they were, they would at most be friends.

But now that he knew that Bai Su was actually a girl, that kind of feeling was as if something that he liked was stolen away by someone.

Bai Su's medicine, there was still a way to make it work. At dusk, Chuchu was no longer in pain, but her body was still weak and she did not want to get out of bed.

Mu Yuntian did not ask Bai Su what happened to Bai Su.

Firstly, he did not care. Secondly, Bai Su's action of letting him bring the people out of the room seemed to indicate that she did not want him to know what had happened to Chuchu.

Faced with Mu Yuntian not asking him about it, Bai Su felt it was kind of funny.

At night, they sat by the window.

Bai Su looked at the stars outside her window, and could not help but sigh, "I wonder if I will be able to make it in time for the end of the Martial Arts Competition …"
