Chapter 105 Definitions of Salutations
There are several laws of simple calculation skills. Bai Tongtong listed several calculus problems. Even students in private schools have not mastered them all. What's worse is that some students from ordinary families even say they have never learned it. What's more, they can't even calculate addition and subtraction within a hundred digits in their minds. These are middle and senior students who are almost 20 years old. Bai Tongtong took a deep breath and temporarily lowered the difficulty, starting from the law of symbol transformation step by step.

Since then, there have been rumors in the school that Bai Tongtong is a terrible math teacher. Every time she finishes a class, she assigns a hundred exercises and submits them for correction in the next class. palm.

Bai Tongtong divided the students who came to the class into study groups of four, set up a group leader, and asked Ai Ni and the three of them to be the group leader. If she had something to do, she would ask the three of them, and then they would pass it on to the group leader below and supervise the follow-up progress.

The teachers privately called Bai Tongtong's class a special training class. In fact, the teachers had discussed about the math class. Those who could master the difficult math content by self-study were all children from upper-class families. There are family teachers who teach targeted knowledge, and the primary education before entering school is also completed in private schools with strict management, which allows them to develop good study habits, which is not comparable to those children from ordinary families who grew up like sheep. .

And back to school, the students who are civilians account for an absolute proportion. The uneven basic level of mathematics is a big real problem, and it is difficult to find high-level teachers. Bai Tongtong volunteered to be a volunteer teacher, which gave the school an observation. Opportunity.

In addition to giving special training to the students, Bai Tongtong herself was not idle. She was busy with her experiments after class preparation, and magic learning was not left behind. Theory and practice were combined into one. The teachers accepted it completely and posted it at the door for everyone to abide by.

Gray mages have obtained so many experimental test materials, and they need a lot of magic circle assistance in a short period of time. Master alchemists like Master Jules are the first choice for help. Sometimes they don’t care about taking students to do experiments. The plan is to send Bai Tongtong to take the class on his behalf. Everyone knows how powerful she is, no one dares to play tricks, obey her words, do whatever she asks, and obediently join the special training class to receive hell-style training. The bright avenue of Xueba rushed away.

Principal Hart said that the observation period is one month, but judging from the performance of the students in the special training class, he is still observing and summarizing after October, and looking for a new math teacher according to Bai Tongtong's quality standards, offering high salary and providing accommodation , allowing family members to be brought, hoping to attract excellent teachers from all over the country to apply.

Taking math classes and leading people to do experiments took up most of Bai Tongtong's time every day, but she still squeezed out some spare time to do her own experiments. The material consumption rate of alchemy students drawing magic circles was comparable to hers at the beginning, and they still went step by step. After learning it systematically, although I feel that my heart is balanced, but at the same time, I also feel that there must be a way to reduce the loss.

Bai Tongtong put his idea on a pencil.

She wants to try to make a special drawing pencil for magic circles, which contains little magic power. Even if she draws a wrong stroke, it is not enough to burn the magic paper. There is a chance to correct it in time, and the formula list of all levels of runes is ready-made. She has to do it The only thing left is to find the right formula for the magic pencil.

Under such guiding ideology, Bai Tongtong first made a lot of resin glue, prepared graphite powder, found the raw materials listed above and processed them into powder according to the formula list of the first-level rune liquid for making the lowest-level scroll, and set up ten different formulas Proportion, mixed with graphite and resin glue to make the refill of a paper pencil, and then try to draw a magic circle on the magic paper to find the one that is closest to the idea in your mind, and then continue to fine-tune the formula to achieve the best effect move closer.

In order to save the time of making refills by hand, she made mirror image array runestones, and then changed to automatic refills in order to save the cost of materials.

After two months of hard work, when I finally found the formula that met the idea, I found that the thickness of the refill is also one of the conditions for the finished product. The automatic refill is the most ideal. If the drawing is wrong, there will be a warning before the magic paper or scroll is burned, but due to the lack of magic power It will not be successful, even if the last stroke has been drawn, it will not be in vain. It is good to correct it, but to become an official product, it needs to be drawn again with talisman liquid, that is, the process of drawing the magic circle is divided into drawing draft and drawing. Two steps for tracing.

Looking at the ugly mechanical pencil that was bare and lacking in decoration and beautification, Bai Tongtong hesitated, wondering whether she should take it out for trial and collect opinions from others. After thinking about it, she still prepared several. I took it out on purpose, and slowly drew a newly learned water-based compound ice cone magic circle on the magic paper. There are ice blades hidden in the ice cone, and the attack range and strength are much stronger than casting magic alone.

As usual, Master Jules asked the students to draw it on the spot to see if everyone understood the content of today's class. This drawing process was of course accompanied by the usual process of burning magic paper. Bai Tongtong drew with a magic pencil and corrected any mistakes. That's it, a piece of paper to draw to the end.

Master Jules, who knew the level of Bai Tongtong's painting array, felt strange. Today is the content of Protestantism. It is impossible to make mistakes in one stroke. Out of curiosity, Jules went over to see what happened, and found that she used a very strange-looking pencil. And it just happened to be a wrong stroke again, a dangerous light flashed on the paper, but it disappeared in a flash, Bai Tongtong calmly wiped off the wrong place with dry bread crumbs and re-drawn.

Master Jules stretched out his hand to Bai Tongtong, hooking his fingers, the meaning was very clear.

Bai Tongtong raised his head, took out another new one, pushed the cap of the pen to push out a medium-length refill, then put the pen into the palm of Master Jules, then lowered his head and continued to draw.

Master Jules held a pen in one hand and a small piece of bread crumbs in the other. He walked to a nearby boy who had just burned another piece of magic paper with an annoyed expression on his face, gave him the pen, and watched him draw again.

He has destroyed several pieces of magic paper in a row. After repeated failures, he is inevitably restless and distracted. He has no time at all. Why did the teacher give him a strange pen, and took out new paper to draw a few strokes? , just subconsciously took a wrong stroke because of too much force to break the refill, the light flashed on the paper was fleeting, and the magic paper was lying on the table.

"Huh?!" The boy screamed suddenly and stood up suddenly. His behavior disturbed the attention of the students around him, and many people complained.

"What are you doing? Make me draw wrong again!"

"I managed to draw half of it in one breath to scare you, and it's useless again!"

"You can paint as you please, what's the name, it's scary!"

"Is there something wrong with the drawing?"

The poor boy couldn't argue, and looked at Master Jules aggrievedly, while Jules put his left hand behind his back, and pointed with his right hand to Bai Tongtong who was sitting diagonally across from him.

Quickly running away, his attention returned quickly, and he saw at a glance that the pen in Bai Tongtong's hand was exactly the same as the one in his own.

"Ah!!" The shout broke down again, and more people stood up to beat him, scaring the poor boy to hide beside Master Jules.

Bai Tongtong swaggered down the pen and stood up, "I'm done."

Master Jules took over Bai Tongtong's classwork without even looking at it. He just pointed to the chaotic classroom discipline around him, "Aren't you going to teach these unmotivated children a lesson?"

Qi Shushua's eyes immediately turned to Bai Tongtong. Unexpectedly, Master Jules accepted the new pencil in this way. Bai Tongtong was relieved, smiled, and took out a cardboard box, which contained a sufficient number of mechanical pencils and small paper bags. Packed replacement refills, one set per person, Master Jules also has it.

After mastering the simple method of use, the students put on new magic papers and began to try them out. There were surprises one after another, and homework writing finally became an interesting thing, rather than competing with each other to see who wasted more materials.

"This really should be one of them!" The students who successfully completed their classwork couldn't help but sigh with emotion.

"Hmph! Why didn't any of you come up with this idea? Thanks to all of you who have been studying for so many years." Master Jules turned pale and glanced at his students majesticly, "Today's homework is changed to drawing twenty different types of paintings. The compound ice cone array, hand it in tomorrow."

This is left to yesterday, these [-] pieces cannot be drawn anyway, because each double formation is a brand new design, with the author's strong personal characteristics and style, there is no ready-made template to apply directly, the exact same result can only be drawn. It could be plagiarizing other people's homework, and the error rate is there. It is destined not to draw a few in a day, but today with this magic pencil, Master Jules will not let the students feel that learning is too easy.

Bai Tongtong also had to do this homework. Master Jules treated her equally in the matter of education, so he didn't care whether Bai Tongtong had extra work, and sometimes he was even stricter with her.

As soon as I heard that there were so many homework today, everyone stopped making trouble, hugged their textbooks and ran away. There are twenty of them, and it takes ten hours to draw one in half an hour.

When he was outside, Bai Tongtong passed the ground escape technique and escaped back to the dormitory several times. He didn't plan to go to the school cafeteria for dinner. He put the box containing the mechanical pencil on the coffee table in the living room first, then rushed back to the bedroom and sat in front of the desk. Open the book and lay out the paper and pen to draw the basic formation of the ice cone. This step is familiar, but the difficulty is the twenty different designs in the back.

After drawing the required basic formation in one go, Bai Tongtong went downstairs to the kitchen to get something to eat for herself, and thought about the design concept by the way.

While preparing the batter to make pancakes, someone knocked on the front door. Ah Huang's hands were covered with flour and he didn't want to open the door, so he called Ah Huang. Ah Huang left the warm fireplace in the living room reluctantly and fled outside to greet the guests. I took it in.

The only ones who would slam the door like that were the three of Ai Ni and the others. As soon as they got to the living room, they screamed, "Tongtong!"

Ah Huang, who was shaped like a half-sized leopard that was full of food, flicked its tail violently horizontally, successfully stopping the excessive decibels of the excited boys and girls, and then raised its paws to point to the coffee table that had not been looked at.

Following its guidance, the three of them finally saw the lonely box, quickly took a set, and then ran to the kitchen to settle accounts with Bai Tongtong, "Don't tell us first if you have something good!"

"I just made it last night, and I didn't have breakfast with you in the morning, so I had to let the students of the alchemy department try it first, and the effect is good. You can try it, and guarantee to save materials. I just have to trace it again. If I make a mistake, it will still be wrong." It was scrapped." Bai Tongtong explained with a smile on his face while pounding the batter.

"Hmph, you are right. I forgive you. You can continue to be busy. Let's go back to have a lunch break." The three who got the things turned around and ran away.

"If I knew that no one had questions about the mechanical pencil, I should have taken it out a long time ago. Paper pencils are such a waste of materials." Bai Tongtong continued to stir the batter calmly and said to himself.

[If it is an ordinary refill, it will still cause problems. Now it is a magic refill. For the sake of my own material costs, who will talk too much in front of you, at most, I will secretly study it behind my back. 】Ah Huang yawned and sat down at Bai Tongtong's feet.

"It doesn't matter. If you have the ability, you can crack my synthesis formula." Bai Tongtong finally mixed the batter, added seasonings to it, lit a fire on the stove and sat in a pan to start pancakes.

[You are a shame. 】Ah Huang rolled lazily on the ground, feeling that it was too cold here, shivering, and went back to the living room.

The news of Bai Tongtong's special pencils spread all over the school in one noon, but no one else except the teachers and senior soil students. She only made so many pencils in one batch, and it was done with the help of the mirror array , the cost is too high to be given away, and other people can only spend money to buy it if they want it.

It’s okay to spend money to buy it, a pencil can save a lot of material costs, even people who are not in the special training class will calculate this account.

Now that everyone is cheering, Bai Tongtong really took the time to calculate the cost, and gave a price, which is roughly equivalent to the price of a bottle of high-grade talisman liquid. It is really expensive, and the follow-up refills will continue to cost money, but a small pack The core can be used for a long time, and it is very cost-effective to think about the material cost saved after having this money.

Two weeks later, the second batch of mechanical pencils and magic refills came out in larger quantities. This time, she specially asked the paper workshop to customize a small paper box for refills. Since it is a business now, of course the packaging work must be done well. , Even coloring agents are added to the resin for making pens, and seven colors of pen barrels are made, with engraved patterns on them, which are not only beautiful but also help to hold hands without slipping.

And in the process of looking for a workshop to do business, Bai Tongtong finally decided to make a loose-leaf notebook for herself. She found a cobbler, bought leather items, drew the lines by herself, and then had the cobbler sew them up, and then customized a copper notebook with a blacksmith. Accessories such as high-quality rings and side strips are combined and fixed on the inside of the leather product with rivets. She also specially added double pockets and pen holders.

The matching paper products are ordered directly in the paper factory. The workers have manual drills for the binding process. Although they are not as convenient as professional punching machines, they are still ok. Bai Tongtong also bought a few standard boxes of ordinary writing paper and magic paper. The paper requires punching, and it took more than a week for pure manual labor to complete.

So this second batch of mechanical pencils is also sold together with this leather loose-leaf notebook that is almost finished.

Therefore, students who come to buy pens will naturally buy two notebooks, one with ordinary writing paper and one with magic paper. Some people even buy two mechanical pencils, one on top of each notebook.

The news spread, and the merchants in the city took action upon hearing the news. Within a few days, a large number of imitation loose-leaf notebooks appeared in various stores, and they came in different sizes. The big ones were like books, and the small ones could be put in jacket pockets, attracting many ordinary citizens to buy them. Thoughtful merchants also provide matching replacement paper cores, and of course perforated magic paper cores are indispensable for stores specializing in magic supplies.

The students all felt unfair for Bai Tongtong. It was her idea, and it was other businessmen who turned around and made a lot of money.Bai Tongtong didn't think it mattered, things without technical content were easy to imitate. Looking at her mechanical pencil and refills, no one could imitate her.Merchants imitated a large number of loose-leaf books and put them on the market. Under the competition, there will be better quality products. In the future, she can directly buy them on the street if she needs them.

Thinking of this, in order to facilitate her future stationery needs, Bai Tongtong took the time to go to the workshop area again, custom-made punched cardboard folders, used to store the semi-finished magic paper she drew, and can save half by making runestones in the future strength.

She came back with two boxes of folders on her front feet, and imitations appeared on the street at her back. It felt as if the workshop that made the folders for her had secretly added a lot of folders and sold them to other merchants.

The Magician Guild came to Bai Tongtong at this time, hoping to buy a large number of magic pencils from Bai Tongtong. Magicians who are good at drawing magic circles are very interested in pencils and loose-leaf books, which greatly facilitates them to draw whenever and wherever possible. It saves time and effort compared with the drafts they could only draw on ordinary paper before.

Bai Tongtong readily accepted the business, worked hard for half a month, and delivered the goods before the winter vacation.

Farrell, who was far away in the royal capital, bought several mechanical pencils in the guild store and did reverse experiments at home, but all of them failed.

[The potential of a cat's partner seems to be beyond our imagination. 】Seeing that the experiment had stopped, Harding slowly approached behind Farrell, and he would not take the initiative to approach this experimental platform full of dangerous goods.

[She has already shown her strength, so she can no longer be called a cat's partner. 】Farrell squeezed a black flame to burn off the useless residue.

[As far as my standards are concerned, if the cat does not sign a contract with her for a day, the attribute attribute in front cannot be removed. 】

【It's a cat, why should you look at it according to your standards?The cat's character changes three times a day, so whatever it is, no matter whether the contract is reached or not, that woman is already able to settle in the country safely, and that's why I helped her. 】

[You're still talking about me, don't use personal pronouns for her. 】

【Then what do you want to call her?Give it a nickname? 】Farrell had a smile on his lips that he didn't even notice. He tidied up the experimental equipment, cleaned up the experimental bench, stroked the pet's head, and took it outside and back to the ground.

[It's still that woman. 】Harding flicked his tail, and the address for Bai Tongtong was decided in this way.
