Young Miss Undercover
Serum X and the Crown Princess

"It's not usually like that. Though brother was happy because of his firm character in teaching. But I didn't think he was acting like that. It must be due to personal vendetta. But what kind of revenge?" Dalfa spoke on their way to the teacher's room.

"Not usually he's like that? Hm. This is really weird. This is the first time we've met. So... What kind of grudges does he keep for me?" Rhiana muttered in thought.

"What's his name, brother?" Rhiana looked at Dalfi who had been silent next to her.

"Sienna." Dalfi answered briefly. Rhiana nodded in response.

"But, Baby... Since when have you been close to that tomboy?" Dalfa asked Rhiana.

"Alvio?"

"Well what his name is, brother doesn't care. It's just that brother just saw her today. His view of you is similar to Brilyan's."

"uh? What kind of view?" Rhiana of course did not understand what Dalfa was saying.

"He Likes you." Dalfi answered quickly. He also realized it.

"That's impossible, brother. I'm just helping him out of some thugs on the way to school. That incident was a long time ago. To my knowledge, he likes Brilyan. He behaved like that because he wanted to thank you. He also once gave me chocolates and flowers."

"What's? How brave of him." Dalfi suddenly let out an unhappy aura.

"Unfortunately, the chocolate and flowers were thrown away by Brilyan and replaced with gifts from him."

"Heh... The man turned out to be quite gentle," Dalfa smiled faintly not expecting Brilyan, the cold man could be romantic as well.

"Don't talk about those that aren't important. This is an email from a confidant. It's about Sienna." Dalfi looked at Rhiana seriously.

"So.. What's wrong with her, brother?" Tanya Rhiana was curious.

"Sienna Pheneass Vajiralongkorn's. The son of the Thai royal family. Her status now was the Crown Princess. He got the position because of his skills. He's the best graduate of the world's prestigious university. He was adopted by the King of Thailand when his adoptive mother died." Dalfi explained calmly. His eyes focused on his phone.

"That means he was adopted before?"

"Yes. He has a lot of skills. The most prominent in the fields of science, technology, politics and law."

"Take it as crown princess." Dalfa opened his voice slowly.

"Don't know why he's a teacher here?" Rhiana was of course very curious as to why that woman had appeared here. His skills are definitely needed in Thailand, especially with his achievements. So, why did he come to be a teacher in Switzerland?

"They haven't found a reason yet. But, her dead adoptive mother was Swiss. Looks like you're making trouble with people in Switzerland. That's why he targeted you.

The crown princess of Sienna was known to the public, especially Thais as a very wise and assertive person. He never punishes anyone. He also never bothered with his power. It's only natural that some nobles support her to ascend the throne even if she's a woman."

"That means he has a good reason to be a teacher here. Of course it's not because of me." Rhiana muttered in heart.

"Sister.. I can tell, who is her deceased foster mother?" Rhiana wants to know who Sienna's foster mother is. That way, Rhiana might find her connection to the Thai crown princess.

"Well, it looks like the power of the crown princess of Thailand is very large. The headmaster of an elite Swiss school that never happens at once and is always honest, turns out to hear his orders. It's really weird." Rhiana murmured after entering a rarely used laboratory whose size was also quite large.

This room was given to Rhiana for self-cleaning as punishment. Dalfa and Dalfi cleaned the room. Isn't it obvious the crown princess's target?

"Get out, Gledy! Help me clean this room. I'm busy." Rhiana then cleaned a chair in the corner of the room where she was sitting to read the results of Gledy's investigation of Annalisha.

"Serum X? It is very useful for brainwashing humans. The underground organization that produces it. The organization must be crazy."

Rhiana sighed for a while before picking up her phone and contacting Marrie.

"Why?"

^^^"I was curious about the serum X produced by that organization. More detail is better."^^^

"Serum X, as far as I've been producing 5 years ago, but only distributed half a year ago. Its main function is to wash the human brain. The way it works is very easy. It is only necessary to give a few drops to the water, then it is consumed.

The one who drinks it his mind will be empty. Staying empty was filled with unreasonable talk, the target's mind was instantly washed clean.

All I hear is that serum X has only been sold in two bottles. But I don't know who the buyers are. Although a bottle is only 10 ml, but the price is also not kidding for a kind of dangerous liquid."

"Serum X, the working time is only a whole month and the wearer will return to normal. If it has been used for a long time, it will become a dependency. The condition of the wearer's body may no longer be helped."

^^^"What about the antidote?"^^^

"If it's produced, there's definitely an antidote. Unfortunately, people who are already addicted no longer need a cure. That's all I know."

^^^"I understand. Can you help me find out who the buyers are?"^^^

"Hm. If in two days you don't get any news from me, check xx email. And. don't forget to keep my family as you promised me."

Call was interrupted instantly. Rhiana stared at her phone quite dumbfounded. Doesn't Marrie's words sound like a will? Is figuring out the buyer of serum X that dangerous?

"Huffff. I don't know who the brains behind their dangerous weapons are." Rhiana suddenly got dizzy thinking about the crime that had been done underground organization long ago.

Based on the results of the examination of Gledy, Annalisha has been consuming serum X since two years ago. Doesn't that mean he's addicted? Rhiana suddenly wondered what Yeandre's response would be if she knew Annalisha's current condition.

...

"I heard from the principal, Rhiana is the first ranked student with the highest grade since the past 10 years. Looks like you're pretty smart,"

Sienna, who has been Rhiana's homeroom teacher for a month and is the most feared math teacher in an elite Swiss school, is currently teaching. The most upset Rhiana, this woman always insinuated him during teaching.

During teaching, the person who is asked to do the most problems is Rhiana. Even Rhiana had to be given many unreasonable questions about the reason she chose the formula and how it worked.

Fortunately Rhiana was the patient type, so she easily answered all those silly questions. Of course Rhiana has high patience, because she is surrounded by people who make headaches.

All of Rhiana's friends were just looking at her with expressions of pity. There were even those who were happy in their hearts because they felt their grudges were avenged.

Sienna, the crown princess of Thailand will give Rhiana very little time to write and explain the answers in front of the class. Although it was only a minute late, Rhiana would be given a punishment. And that punishment must have drained his energy. Fortunately there was Gledy, so Rhiana did not need to waste her energy in vain.

And today, this killer teacher is starting to act again.

"It must end soon" Rhiana murmured inwardly.

Rhiana was patient enough with Sienna's behavior. That two weeks had passed, and Rhiana was still treated like a mortal enemy. The school could not do anything, making Rhiana have to be extra patient.

Even if Rhiana wants, there are three protectors in the class who are ready to help. But Rhiana rejected their offer and would let this crown princess continue to intimidate him.

"An observer is at the top of the tower with a height of 120 m. He saw boat A with a distance of 130 m and saw boat B with a distance of 150 m. If the base of boat tower A and boat B are in line, then the distance of boat A to boat B how many meters?"

The class whispers at once questioning what wrong Rhisna has done so she is always the target of Killer's teacher.

The question that was read was very fast and not even repeated again. They have not even finished recording the problem, especially considering what this actually has to be done with the formula. Not to mention, the language used was the newly learned mandarin.

Mandarin has just been included in the curriculum of an elite Swiss school, so all students have difficulty learning it. The principal added mandarin to the study, as Swiss elite schools several months ago teamed up with leading schools in Hong Kong for exchange of students and faculty.

Although they always communicate with international languages, but the headmaster of the elite Swiss school wants its students to learn Mandarin as a form of respect for Hong Kong.

Hearing the matter the crown princess read, Rhiana frowned. Why was he given such a simple matter? This is the pythagorean theorem taught in the first degree. What is this woman planning?

"You have 1 minute to answer."

A minute? For Rhiana it is not difficult. He already knows the answer. Mandarin itself has been studied since childhood for the smooth mission in the future. The problem is, one minute equal to 60 seconds is not enough time for him to write an answer to that question.

Brilyan next to Rhiana had fallen into thin air because she herself had not finished translating the matter. How can he help? The man was frustrated.

While Dalfa and Dalfi also can not help because of the distance of their seats. They will be caught if they help.
