Exquisite, gorgeous, charming, and every detail made Rosen feel familiar. Just the day before, he had seen a similar temperament in the vampire Viken.

‘This woman is not a high-level vampire, isn’t it?’

‘If it were a high-level vampire, why would it appear in a small place like Sunderland?’

‘Will it have something to do with the vampire Viken? Will she sense the blood mark magic on my body?’

After a breathing, countless thoughts flashed through Luo Sen's mind, and subconsciously paused. Then he suppressed the thoughts in his heart and walked towards the tavern counter.

‘The vampire has a very sharp sense. If I perform abnormally, it will definitely attract her attention.’

Walking to the counter, Rosen smiled slightly at the waitress behind the counter: "Girl, a glass of ale, a bowl of boiled potatoes."

"No problem, give 8 bronzes."

After paying the bill, Rosen walked towards the corner with ale and boiled potatoes.

Anyway, he was hungry, so he stopped thinking about it and started eating ale and potato fields.

Just as she was eating with relish, the girl in front suddenly sat upright, took out a roll of blank sheepskin from the bag hanging on the chair next to her, a bottle of ink and a quill. She dipped her quill in ink and began to write something on the parchment paper.

Rosen didn't dare to look at it for too long, and glanced at it and withdrew his gaze: "She is writing a letter? Looking at her, she seems to have not noticed me at all, that is, she should not be able to sense the blood mark magic on my body?"

‘That’s right. Every advanced vampire’s blood mark magic is unique, and they are usually only sensitive to the blood mark magic they release.’

‘It may be that I was wrong. Maybe the other party is not a high-level vampire at all, but just is just beautiful.’

Thinking of this, Rosen relaxed a little. He stopped paying attention to the other party and began to concentrate on eating the food.

Just when he was almost forgetting that girl existed, the girl in red turned around, waved to Luosen, and smiled and said, "Come here."

Because of this action, Luo Sen saw the other person's appearance clearly, his burgundy eyes, his high nose bridge, his small lips, his skin like white jade, and his facial features were so delicate that it was beyond words, as if he was walking out of a painting.

When she smiled, her eyebrows and eyes were curved, and she felt a sense of charm that hit her soul directly.

‘This is simply a goblin!’

Luo Sen was amazed, but more nervous.

‘Why did she look for me? Could it be that she sensed the blood marks in my body? Don’t really have a high-level vampire!’

The girl in red certainly didn't know what Rosen was thinking. She smiled and said, "Little guy, I'll ask you, have you learned geometry?"

"What...geometric?" Luo Sen was stunned.

He always suspected that the other party was a vampire, and was even more worried that she would appear in order to investigate the disappearance of the vampire Viken, but the other party asked him if he understood what he understood?

This is a wrong style.

The girl in red saw Luo Sen dazed and shook her head in disappointment: "Looking at your clothes, I guess I am a child from a wealthy family. I haven't learned how to learn how, it's such a pity."

She sighed, turned around, and continued to draw on parchment with a quill pen, sometimes pausing and frowning, sometimes writing quickly, with a very focused expression.

Luo Sen quit here. He has been a top student since he was a child. Especially in mathematics, he has not only scored every time, but also won the gold medal in the Olympics. Now it is actually thought that he hasn't learned much?

It's a great shame!

Of course, Rosen was still a little rational. The girl in red had unknown origins. He would not come up to prove himself just by just a word from the other party.

However, it is still OK to secretly look at the parchment in front of the other person.

‘Hmph, I’m so angry, I want to see what you have!’

Thanks to this body's outstanding vision, although the light in the tavern was dim and four or five meters away, Rosen could barely see the contents on the parchment.

There are various geometric figures drawn on the parchment paper, such as triangles, squares, circles, etc.

After a few glances, Rosen confirmed that the other party was studying the problem of plane geometry. At the beginning, she proved the Pythagorean theorem of a right-angle triangle, and then proved that two triangles were in line with each other. All these... After doing more than a dozen simple plane geometry problems, she finally drew a curve and then stuck there motionless.

Luosen waited for a while, but the quill in the other party's hand still stopped there and his brows were locked and he had not let go.

‘Hehe, have you encountered a problem?’ Rosen gloated.

He looked at the curve on the other person's paper carefully, and after a while, the smile on his lips became stronger: "Small, with the skill of plane geometry, you still dare to study logarithmic spirals? You will spend your whole life on this, haha~'

On the earth, according to the order of development, the most basic thing is plane geometry, then three-dimensional geometry, and then Cartesian introduced the coordinate system, which allowed the analytical geometry, and then there were non-Euclidean geometry, differential geometry, intrinsic geometry, topology, etc.

The difficulty and order of these geometric classifications are basically the same as the order of occurrence. Planar geometry is the simplest. At the topology stage, the development of geometry has reached an extremely abstract state. If ordinary people do not study hard, they are basically unable to understand the content of topology research.

If you want to understand the logarithmic spiral, you must at least reach the analytical geometry and introduce calculus. With your personal power, you can develop the two mathematical tools of coordinate systems and calculus without any foundation. That is a dream!

So, if this girl in red really wants to fight the logarithmic spiral, she will basically not have to do anything else in her life.

Although he felt secretly happy, Luo Sen didn't plan to join in the fun. After eating the last two potatoes in his hand, he drank the ale that was as light as water in one mouthful, clapped his hands and prepared to leave.

Unexpectedly, as soon as he raised his legs, the girl in red suddenly looked up at him: "You were laughing just now. You know geometry, right?"

Luo Sen staggered and hurriedly held the table with his hands, then he stabilized his body, and his heart was already filled with storms: "How could the senses be so sharp? I obviously peeked at it carefully. It's over, I'm not wrong. This woman is probably a high-level vampire!"

Rosen's heart couldn't help but pound.

The girl in red frowned: "Your heart beats very fast."

‘Done!’

Rosen was scared again. When he was panicking, his mind suddenly flashed and he had a solution: "Madam, this is because you look so beautiful."

"Haha, what a sweet mouth." The girl in red covered her mouth and chuckled: "It seems that you have a good brain, and you should learn geometry well, right?"

Luo Sen secretly complained: "I have learned it, but my level is average."

"It's okay. Since you have learned geometry, let's help me see this question. Well, you can't refuse~"

Luo Sen really wanted to slap himself.
