The Last Alchemist

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

'Could this woman be a high-level vampire?'

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

‘Could it be related to the vampire Viken? Will she sense the blood seal magic on my body? ’

In just one breath, countless thoughts flashed through Rosen's mind, and he paused subconsciously. Then, he suppressed his thoughts and strode towards the bar counter.

'Vampires have very keen senses, and if I behave 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 and a bowl of boiled potatoes."

"No problem, I'll give you 8 coppers."

Rosen paid the bill and walked toward the corner with ale and boiled potatoes.

He was hungry anyway, so he stopped thinking about it and started eating with a sip of ale and a bite of potatoes.

While eating with gusto, the girl in front suddenly sat up straight and took out a roll of blank sheepskin, a bottle of ink and a quill from the leather bag hanging on the chair next to her. She dipped the quill in the ink and started writing. Start writing something on the parchment.

Rosen didn't dare to look at it for too long. He glanced at it and then looked away: 'Is she writing a letter? Judging from her appearance, she didn't seem to notice me at all. In other words, she shouldn't be able to sense the blood seal magic on my body? ’

‘That’s right. The blood seal magic of each high-level vampire is unique, and they are usually only sensitive to the blood seal magic they release. ’

‘It’s also possible that I guessed wrong. Maybe the other person is not a high-level vampire at all, but is just beautiful. ’

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

Just when he almost forgot about the girl's existence, the girl in red turned around, waved to Rosen, and said with a smile: "Come here."

Because of this action, Rosen could clearly see the other person's appearance, including burgundy eyes, a tall bridge of nose, small lips, and skin like mutton-fat white jade. His facial features were so delicate that they seemed to have stepped out of a painting. Similar.

When she smiles, her eyebrows are curved, and there is a sense of charm that directly touches her soul.

‘This is simply a monster! ’

Rosen was amazed in his heart, but even more worried.

‘What does she want from me? Could it be that he sensed the blood mark in my body? Don't be a real high-level vampire! ’

Of course the lady in red didn't know what Rosen was thinking. She smiled and said, "Little guy, let me ask you, have you ever studied geometry?"

"How much?" Rosen was stunned.

He had always suspected that the other party was a vampire, and was even more worried that she appeared here to investigate the disappearance of the vampire Viken, but the other party asked him if he knew geometry?

This style of painting is wrong.

Seeing Rosen stunned, the girl in red shook her head in disappointment: "Looking at your clothes, you must be a child of a wealthy family. It's a pity that you haven't studied geometry."

She sighed, turned back, and continued to draw on the parchment with her quill, sometimes pausing and frowning in thought, sometimes writing furiously, looking very focused.

Here, Rosen has stopped working. He has been a top student since he was a child. Especially in mathematics, he has perfect scores every time and even won an Olympiad gold medal. Now people think he has never studied geometry?

What a shame!

Of course, Rosen still has some sense. The origin of the girl in red is unknown, and he will not rush to prove himself just because of the other person's words.

However, it is still okay to secretly glance at the parchment in front of the other party.

‘Hmph, you are so loud, I want to see what you are capable of! ’

Thanks to this body's excellent eyesight, even though the light in the tavern was dim and the distance was four to five meters, Rosen could still barely see the contents on the parchment.

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

After a few glances, Rosen determined that the other party was studying plane geometry. At the beginning, she proved the Pythagorean theorem of a right triangle, and then proved that two triangles are congruent, and so on. After doing more than a dozen simple plane geometry problems, she finally drew a curve, and then It was stuck there motionless.

Rosen waited for a while, but the quill in the other person's hand still stood there without moving, and his brows were furrowed and he never let go.

‘Hey, are you having a problem? ’ Rosen gloated.

He looked at the curves on the opponent's paper carefully, and after looking at them for a while, the smile on his lips grew wider: 'Young man, with this little knowledge of plane geometry, you still dare to study logarithmic spirals? Just spend your whole life on this, haha~'

On the earth, according to the order of development, the most basic is plane geometry, then solid geometry, then Descartes introduced the coordinate system, and then there was analytic geometry, and then there were non-Euclidean geometry, differential geometry, intrinsic geometry, topology, etc. wait.

The difficulty of these geometric classifications and the order of appearance are basically the same. Plane geometry is the simplest. When it comes to topology, the development of geometry has reached an extremely abstract state. If ordinary people do not go through arduous study, they will basically It is impossible to understand the content of topology research.

If you want to understand the logarithmic spiral, you must at least learn analytic geometry and introduce calculus. Relying on one's own strength to develop the two mathematical tools of coordinate system and calculus without any foundation is a fool's dream!

Therefore, if the 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, Rosen had no intention of joining in the fun. He finished the last two potatoes in his hand, drank the ale that was as light as water in one gulp, clapped his hands, and prepared to leave.

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

Rosen staggered and hurriedly held the table with his hands before he stabilized his body. His heart was already filled with turmoil: "How could my senses be so sharp? I peeked very carefully." It's over, I guessed it right, this woman is most likely a high-level vampire! ’

Rosen's heart was beating uncontrollably.

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

‘It’s over! ’

Rosen was frightened again. Just as he was panicking, a sudden flash occurred in his mind and he had a countermeasure: "Madam, it's because you are so beautiful."

"Haha, you are such a sweet talker." The girl in red covered her mouth and chuckled: "It seems that you have a good brain, you should be good at geometry, right?"

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

"It's okay. Since you have studied geometry, come and help me look at this problem. Well~ I can't refuse~"

Rosen really wanted to slap himself.
