When she returned home in the evening, Serena talked to the Duchess about what had happened in the academy today. Avril saw that she was a little listless, and didn't mention Meiyi, who never left her mouth every day, knowing that something unpleasant might have happened to the two, so she asked her, "By the way, how well do you control your spirit?" ”

When Serena heard this, she suddenly came to her senses, and said a little proudly: "Madam, you can see it by looking at it, Teacher Kristia is also surprised to see her today." I'm the one who has done the best job of Lingzi control in our class. ”

When the Duchess saw the wind ball triggered by Serena moving slowly in the air, as smooth as a ball rolling on the floor, she couldn't help but open her mouth wide: "Nana, you are so powerful, your control is similar to that of Esther in the Purple Stripe period." ”

Serena said, "I'm not doing enough," but she was overjoyed. The Duchess's face changed, and she stared at Serena tightly, "Nana, did you secretly practice spiritual magic before entering the academy?" ”

Serena's heart tightened, the Duchess had never spoken to her so fiercely, and she stammered a little, "No, no." ”

The Duchess let out a long breath: "Great. Spiritual magic must be practiced at the age of fifteen and as an adult. Remember? Two years ago, Esther said you could learn spirituality. You can't wait for her to come back from the mission, find a wind spirit book, recite an intermediate spirit spell, activate a large number of spirit children, and almost kill yourself. ”

Serena remembered the affair and was a little embarrassed, and she asked, "Madam, why does it have to be placed after the age of fifteen?" ”

Madame said: "The blood of the spirit is not blood, it can be regenerated, but it is a constant quantity, and the use of spirit magic before adulthood will cause a large number of pieces of spirit blood to die, and the potential of the person with the ability of spirit magic will be consumed. Your Lingjie has already lit up six spirit beads, which is a high level of talent, and it is only a matter of time before you light up all the spirit beads. ”

"But if you secretly practiced before the age of fifteen, six spirit beads are probably your limit. Even if you try hard, you won't be able to light up more than ten spirit beads. The wind spirit technique is a relatively weak spirit art, and if you don't light up all the spirit beads, I'm afraid you won't even be able to pass the green vein test......"

Serena didn't listen to what Madame said next, and she didn't know how she had left her room. She struggled to support herself after taking a shower and lying on the bed. When it rained hard outside the window, she began to cry.

It has been her dream since she was a child to become a great psychic like Princess Celestia, sweep away magical beasts, and discover the secret treasures of ruins. However, because of his greed, his dream was shattered in advance.

Now she doesn't know what the meaning of being alive is.

When Serena walked into the classroom in despair, Xingchen, who didn't notice anything at all, said: "Serena, there will be a monthly exam next week, and the three of us have discussed it and decided to do homework together in the library after class in these two weeks, and you can do it together." ”

Serena smiled faintly: "Thank you, no need, I'll study at home." ”

Mei Yi felt that Serena was a little strange and wanted to ask why. But Serena hated him so much that it was inconvenient for him to ask.

When Serena put her school bag, she found a letter in the belly of her desk, and when she looked up, she found that Istin, the fire spirit master in the class, was looking at her with fiery eyes. She threw the letter in the trash without mercy under his gaze.

Istin has been pursuing Serena for a while, and after being assigned to a class, he will stuff love letters in Serena's desk every now and then, and Serena will directly ignore them every time.

In all fairness, Istin, who is tall and handsome, is the son of an earl of a county under Hua Ling, and his family background is very superior. In his group, there are Red Leaves, a fire-based spiritual ability, Fengzi, a fairy healer, a wind-based spiritual ability, and Luo Ze, a water-based spiritual ability, and his comprehensive strength can be called the first in the class.

But Serena just doesn't call him.

After a day of school, Serena got into the carriage sent by the Duke's palace and went home. Liuxi caught up, and just as she wanted to ask her, Serena smiled slightly, "He called you here, tell him that I'm fine, don't bother him!" ”

After school in the afternoon, Xingchen, Liuxi and Meiyi came to the library to do their homework together. Located on the east side of the teaching building, the library has a collection of nearly half a million books, making it one of the libraries with the largest collection of books in the Elven Kingdom.

As soon as the three of them entered the library, they saw Kira waving at them. Kira led them into a study hall that had been occupied a long time ago. Mei Yi briefly introduced each other, and the four of them began to do their homework, agreeing to do math first.

Mei Yi finished the math paper with three strokes and five divisions by two, and completed her grammar and theology homework without difficulty. He had never heard of rhetoric in his previous life, and after taking a few classes, he found that it was to teach people to debate, and it was similar to arguments on paper.

Suddenly, my brother was a staff member of the world's island government in his previous life, so how can I stand with me?

When Mei Yi completed all the tasks as easily as Tomoko destroyed the human fleet, she stretched her arms with ease. He found that several of the others had not finished half of their math papers.

Qiluo saw that Mei Yi was sitting there uncomfortably, so she said, "Hurry up and do your homework...... As soon as she saw the four test papers densely written in Mei Yi's hand, she took them over and looked at them in disbelief, and said in dismay, "You...... Finished writing so quickly? ”

When Xingchen and Liuxi heard this, they came over to look at it in disbelief, and cried out in surprise, one eye glowing golden and the other glowing blue. Mei Yi hurriedly said: "You hurry up and write your own, and we'll answer after writing." Hey, Liuxi, don't copy it. Xingchen, do you want to memorize it all before writing it on your own paper? Stop! ”

Mei Yi took a look at the math test papers of three people and found that several people were very wrong. And they are not to blame, the world's math textbooks are not systematically written, too confusing, and confusing students. In fact, the difficulty of these questions is as idiotic as the thinking questions left behind in the math textbooks of the previous life.

He couldn't stop the three of them at all. Their state is like a college entrance examination candidate who suddenly gets a standard answer, frantically copying it. Mei Yi sighed and said helplessly: "Forget it today, from tomorrow onwards, make up lessons with me after school." ”

The three of them agreed in unison.

Mei Yi thought for a moment and asked Kira, "Do you have a blank scratch paper?" I want a lot and a lot. ”

Kira said, "I will bring you as much as you want, and I will bring it to you tomorrow." ”

Mei Yi sent the three of them to the gate of the college, and after seeing her family pick them up, she went back to the small dormitory and flipped through some things to eat, and then returned to the library, asked the librarian for a few pieces of paper, and after thinking for a while, she put down her pen to write and draw.

The next day, Mei Yi brought a pile of manuscript paper from Kira and put it on the table, still meditating, writing and drawing. Qiluo saw that his brows were tightly knit and he was ecstatic after thinking about it, and a strange feeling appeared in his heart.

A week was over quickly. On the two days off, the librarian was surprised to find that the human student had been in the library's study room for almost two full days.

Just when Mei Yi went to eat at noon on Sunday, she quietly flipped through the thing Mei Yi had written this week called "Why is it difficult to shit math", and she was so frightened that she was stunned on the spot. Although she is not good at math, she can still recognize the weight of the book written by Mei Yi.

Algebra, Sets, Plane Geometry, Solid Geometry, Algorithms, Statistics, Probability, Trigonometric Functions, Vectors, Sequences, Inequalities...... Almost all of the world's research results in the field of mathematics are included in it.

It also includes many axioms, theorems, and formulas that are not part of this world.

What is rare is that this book meets all her imagination of a textbook, simple, easy to understand, with derivative process, illustrations, and especially systematization, and is no longer a few words scattered in the difficult and obscure discourse of various mathematicians.

Star, Ryushi, and Kira, who are enjoying their rest day at home, don't know that their week of hell is just around the corner.
