The days of learning black magic in another world

While the little duke was squatting and lifting iron, Riemann came to Springs College to take the entrance exam.

The entrance exam was scheduled for a leisurely afternoon, and Riemann arrived an hour earlier, which fully demonstrated his respect for the exam—the last time he went to the exam room so long in advance was the college entrance exam.

Then he saw all kinds of candidates.

For example, as soon as the carriage stopped, he rushed down from the carriage and helped the carriage to vomit a thoroughly drunk man. After vomiting, he took out a handkerchief and wiped his mouth. He was so drunk that he still asked Riemann in a "polite" manner. : "Excuse me, is this Springs College?"

Riemann took a step back calmly, nodded with a smile.

"Oh! I'm awesome! I drank ten glasses of Sidney from morning to noon, and I was able to find the place for the exam in time. It's really me!"

Riemann: "I think maybe you should be grateful that your coachman didn't drink."

The other party smacked his lips, touched Riemann's words again, and clapped his hands happily: "Yes! You are right! You are so right! You are such a smart boy!"

After saying this, he seemed to have just noticed that Riemann was a child, and suddenly turned to him curiously: "Son, what are you doing here? Did you come with your father?"

Although generally speaking, students who join Springs College are students who have just graduated from public or private schools and are students in their eighteenth or nineteenth year, but since Springs College is the best university in Wulang, there are often two A 30-year-old gentleman came to the exam with his family.

So the drunk man had no problem asking this question.

Riemann shook his head: "No, I am a candidate."

"Oh!" The drunk man reacted for a while, and suddenly became happy, "So, you are a child prodigy?! That's great, that's great... I really envy you child prodigies, I'm different, I'm just a fool, I am born to be drunk and dreamy, but my father doesn't believe in this evil, and insists on me taking this boring exam..."

The drunk man sighed and pulled Riemann to pour out his bitterness: "What circles, what triangles, what parallel lines, I am really fed up with these! Idiots shouldn't learn mathematics!"

"I'm an idiot!"

This powerful statement made everyone around turn their heads.

Riemann: "..."

I really want to knock this guy out with black bread.

Why on earth did he come to the examination room early? ? ?

When the gate of Springs opened, Riemann almost "fleeed" in.

It's a pity that it's useless for him to run fast. All the candidates must gather at the door to verify the admission certificate, and then the person who leads the team will take them to the auditorium for the exam.

So this damned drunk, probably out of some strange fledgling plot, followed Riemann all the way to the auditorium, and also chose the exam seat next to him.

Riemann's fingers were about to move, as long as this guy said a word, he would really knock him out!

What saved the drunk man was a shout from the chief examiner——"The exam begins!"

Riemann got the test paper, glanced at it, and got a general understanding of the mathematics level of the world.

Just as he judged before, this world may not even have signs of calculus. After calculus, there have been some major changes in mathematics, such as from static to dynamic, such as from finite to infinite.

Before calculus, ancient civilizations such as Greece and Babylon had a high level of mathematics, but they were limited to static mathematics. They could accurately calculate the area of ​​strange geometric figures, but they could not calculate the relevant quantities of moving objects.

Similarly, before the advent of calculus, infinity was a confusing word. How to find the sum of infinite numbers is scary and absurd. It was not until Newton came up with the generalized binomial theorem that infinity seemed tameable. some.

For a student who has received nine years of compulsory education in the 21st century, calculating the speed and acceleration of a moving object is a basic operation, but for people in this era, it is unimaginable. Let their brains understand this The calculation process is very difficult, just as understanding the theory of relativity is very difficult for us.

Therefore, most of the questions that appear on this test paper are geometry questions, and a small part is due to some difficult calculations. I am afraid that it is not only the best mathematician in this country, Achill Monroe, who specializes in geometry, but because They can't test more content.

It took Riemann some time to finish the paper, and he wanted to sit still and wait for others to hand in the paper.

But the smell of alcohol on the drunk man next door came to his nose intermittently, making him recall the miserable days of living next to the sewer—in simple terms, he would vomit if he sat down again.

So he stood up and handed in the paper ahead of time.

Unlike what he imagined, he might be questioned by the teacher who collected the papers, maybe he would have to spend a lot of time talking, or simply let him go back and sit for another half an hour. The teacher who collected the papers looked at his name and immediately He sighed in admiration: "So it's Mr. Monroe's new student!" and let him go.

Riemann breathed a sigh of relief, and before leaving the auditorium, he glanced at the drunk man in a strange way.

It seemed that the other party had eyes on the top of his head, as if he could see Riemann turning his head, and immediately raised his head from scratching his ears and writing quickly, showed a huge smile at Riemann, and gave him two thumbs up.

Riemann: "..."

After leaving Springs College, Riemann was not in a hurry to return to the Duke's Mansion.

He walked to a secluded alley, took out [Insight of the World · Remnant] from the system, put it on, and activated [Concealment that does not belong to the night].

He was going to the black market that belonged to magicians.

Baron Erreira wrote in his diary that compared to the black market in Wangcheng, the crow in Bartley County is really black, a black merchant who is so black, such as 1kg of mithril, that crow charges 100 silver coins, Wangcheng The magician only sells 50 silver, so when Riemann left Bartley County, he did not go to the crow to stock up, but planned to go to Wangcheng to buy other materials needed for equipment.

He intends to give priority to making weapons and rings. Needless to say, weapons, the mana recovery spell on the rings is destined to be second only to magic robes and weapons in priority.

Baron Erreira's diary also wrote that after entering any sewer entrance in the royal city and entering the underground drainage system, only the poor and magicians will go to the underground drainage system, then walk along the direction of the city gate, and you will encounter a strange wall, and then Cast any spell on that wall, and the wall will let you pass.

When Riemann saw this passage, he sighed. Is his life in another world bound to the sewer?

But it's useless to think too much. After he jumped into the sewer, he switched his appearance to a pure black cloak. The reason why it took so much trouble is because his own magic robe is too conspicuous, but the sewer is not suitable for wearing his windbreaker , here, only the black cloak is the universal attire.

In order not to endure the smell of the sewer for too long, he chose the entrance that was closer to the city gate, and he saw the wall after walking for a long time.

"Summon Wind."

A breeze blew by, allowing Riemann to finally breathe smoothly. If it wasn't for the fear of not having enough magic power when encountering danger, he really wanted to blow all the way [Summon·Wind].

The mottled and dirty wall melted into a hole the height of a person, and Riemann walked in and saw the so-called "bazaar".

Some black robes whose faces could not be seen stood beside the pillars, with the things they were selling in front of them, and the distance between each booth was at least ten meters.

The black robes who want to buy things are also far away from each other. If there is already a black robe looking at a stall, the others will definitely go around.

This should be the "most lively" market Riemann has ever seen.

He looked at the stalls one by one.

"Mithril 4kg, goblin cloth [-] meter."

"Three wind crystals."

"Are there ghost vines?"

Fortunately, what he wanted were some common low-grade materials, and he got them together quickly, and it only cost him less than five hundred silver coins, which was much cheaper than buying from the crow.

After getting the required materials, Riemann didn't dare to put the things in his backpack here, so he started to visit the market with this pile of things.

The magicians who sell things in the market are divided into four categories, one is selling raw materials, and the other is selling potions. Riemann dumped a few identification techniques on it, and there are healing potions with relatively normal effects, and there are also Some weird things, such as the result of the appraisal is "drinking the dream potion that can enjoy illusions for twelve hours."

The third category is to sell equipment, there are finished products and customization, and they don’t look as advanced as those in the Riemann system.

The last category is some miscellaneous sundries.

Riemann felt that he should make some potions to sell, and the equipment would be fine. He is only one ring now, so it makes no sense to rush to increase the combat power of potential enemies.

It is also best to sell healing potions for potions, as long as there is cash in the account, and the accounts must be balanced, otherwise Mr. Monroe will wonder where his money has been spent sooner or later.

So he looked through the system's potion refining skills on the spot. There are only two types of potions he can make now-[primary blood recovery potion] [primary magic recovery potion].

The name is very simple and rude, the effect is the same as the recipe he learned before, and the ingredients are not as easy to find as those two foods. [Potion refining] has a failure rate, so he has not touched this potion for the time being. .

However, considering that it has to be sold, the food-type blood recovery medicine feels a bit shocking, and he also needs to prepare the recovery medicine when he fights. It always feels difficult to take out lamb chops and cream soup while fighting. .

Thinking of this, he turned to the stall selling primary potion ingredients.

"The corpse of the Moran worm, the eyeballs of the toad, and the moonlight grass... fifty copies each."

"Two hundred silver coins."

Riemann took the materials and walked to the next stall, which was a sundry stall. The things on it ranged from books written in unknown languages ​​to crystal balls with broken corners.

Riemann threw the identification techniques one by one, nothing special, and decided to go back after shopping around.

He returned along the same path, intending to get out of the wall and put the things away.

"Summon Wind."

A breeze blew by, and a hole taller than a person appeared on the mottled wall again, and Riemann's figure disappeared behind the wall.

"Corrosion · accompanying."

A figure emerged from the darkness and stood where Riemann had just left. A hoarse voice sounded. After chanting a spell, the wall cracked again. The black robe raised his head and saw the back of Riemann who hadn't left yet. A stiff smile curled up at the corner of his mouth.
