Black particles in the air gradually fell, marking yet another failure of the experiment. Xiao Liu didn't know what to say to the creature in front of him, who was almost immune to all magic-related abilities that directly acted on his body. At the same time, it was incomprehensible that he would not be harmed by magical energy, but it did happen to him.

"The master...... I ......" Ke Zhou asked while touching his head, smiling bitterly. In his opinion, Xiao Liu's face was full of despair at the moment, and he had even begun to tear up some books that looked very old to vent his anger. As if he was crazy, he threw the torn pages all over the ground, which made Ke Zhou, who had never seen a magic book, feel distressed.

Until he saw that these books were actually empty, he was really distressed. However, after Xiao Liu said that the pile of books were just blank notepads, Ke Zhou also joined the ranks of tearing books.

"Why, I finally crossed it once, but it turned out that I still had a physique that couldn't touch magic. Ke Zhou spat bitterness into the air, tore the book and threw it on the ground, and stomped a few more times after throwing it. And Xiao Liu next to him was even more serious, obviously he was already middle-aged, but he was playing more happily than Ke Zhou, and the whole person was crazy and attacked the empty notebook on the ground or on the table with various colors of magic.

It took about a few minutes for the two of them to calm down and collapse in the chairs next to them.

"Master, can't you really send me back? I'm an ordinary person, I don't even have the slightest magical ability, how can you let me live in this world. Ke Zhou asked Xiao Liu, who was also paralyzed, in despair, and all he got was a desperate smile, "It's not that I don't want to, it's that I really can't do it, the ghost knows how I summoned you." He banged on his head and continued to slump there like a corpse.

After a few more minutes of silence, Ke Zhou finally figured out something and eased up, "Master, can you tell me about your world?" he asked Xiao Liu, after all, at this point today, he had to start thinking about how to survive in this world.

Xiao Liu thought for a while and pointed to the door of this room, "Go out and turn right and go straight, there is my library, there should be everything you want to see." ”

After he finished speaking, he sat up from the couch, "Since you were summoned by me, then I will also fulfill my master's obligations." That way, I can get you a spot in any academy except the Wizard Academy, or the Swordsman's Guild, or the Hunters' Guild, or whatever. What do you think?" he asked Ke Zhou - his actions were quite polite, after all, in fact, from the very beginning, he did not need to be responsible for the summons.

It's just that maybe because the target is a human being, he has a little moral guilt, so he wants to make him at least have an arrangement. It's just that even he doesn't know if Ke Zhou's small body can withstand it—or let him deal with things like business? After all, I don't know what his business ability is, and business seems to be even more distant.

"I want to go to your study and make a decision, is it okay?" Ke Zhou gently pushed open the door, looked at the room on the other side of the aisle, and turned to ask Xiao Liu.

Xiao Liu nodded, "You can make decisions slowly, not in a hurry at all...... If you can't, you can be my deputy. After all, I've been studying the theory of magic. It's all left over from the ancestors, and now people can only use it but don't know the principle, so magic has developed to a stagnant stage, and there are few new magic. ”

He said, as if he sighed, "So, if you're willing to stay and study with me, it's not bad, anyway, it's magic theory, you should be able to help me a little bit." After he finished speaking, he walked behind Ke Zhou, patted him on the shoulder, and then walked to another room, which was probably the place where he studied.

Ke Zhou didn't have much to do, so he had to obediently walk to the study. This study was huge, even larger than the living room, and contained about thirty or forty bookcases—something Ke Zhou hadn't expected. He always thought that not many people would write books in such a magical world, but when he saw some novels such as "The Legend of the Brave and the Dragon", "Swordsman" or "The King of the Sad Land", he felt a wonderful sense of fit.

After searching for it, he found a book called "The General History of the Earthquake", which looked so official that it even had the logo "Harnell School of Magic Press" printed on it. Ke Zhou didn't think much about it, and opened the book—he had to quickly understand what the world was made of.

The world is divided into several large regions, much like the Earth is divided into continents. It's just that these names are relatively difficult to remember, so Ke Zhou didn't care about them at all. He only remembered that the place where they were located was called the Medium Earthquake, which can also be called the Medium Earthquake Continent, and it was by far the largest area on the planet. In addition to this area, there are 5 different areas. The areas are separated by large rivers or oceans.

Historically, magic seems to have existed since the very beginning, and no one knows how magic came about, and many people have been exploring it. But until now, they have not even figured out the principle of magic and the composition of the magic array...... Not to mention researching new magic.

Some of the magic of the side doors is gradually lost, and the main magic is known to everyone, and the family relies on the continuation of the powerful magic passed down from ancient times, and it is difficult for the Hanmen to compete with those who have been using the family magic for a long time. And each family can also be divided into high and low.

In other words, the whole society, the whole country, and even the whole world are in a strange circle of deformity. In the novels Ke Zhou has read, either it is talent or hard work. Only there is something strange about this world, the role of talent is not as important as imagined, and effort is not so important. The most important thing is that it has become the power of the family and the magic left over from the ancients.

"Damn!" Ke Zhou wanted to slam the book on the ground to express his anger, but reason told him that it was Xiao Liu's book, and he calmed down. Sitting on the ground, it became even more decadent than before.

Confused, confused, and not knowing where to go in the future, all kinds of emotions were mixed together, which made Ke Zhou a little unbearable. He sat quietly on the ground, and at this moment he didn't even have the desire to turn the page.

For some reason, a parchment suddenly landed on his head—perhaps he had touched it while he was holding the book, causing it to fall off the edge of the cabinet. Immediately afterward, the parchment rolled down his head and finally stopped on his lap, where he remained silently.

Ke Zhou opened his eyes slightly, looked at the parchment roll, put his right hand on it weakly, and then slowly opened the parchment roll. There was no golden light, no souls, no adventures, or anything else.

Inside the parchment scroll is the appearance of a magic circle, which very standardly stipulates the length, width, and height of the magic circle, as well as the distance between those circles, as well as the standard writing of various characters. Just looking at the drawings, this magic circle was unusually neat, giving him a feeling that a normal person could draw such a magic circle.

Next to this circle, the function of this circle is marked, as well as a lot of handwriting that seems to be left by Xiao Liu:

"Removing the third circle from left to right at the top will not affect the magic. ”

"Removing the sixth character on the left from top to bottom will not affect the spell holding, but will weaken the spell effect slightly. ”

"Removing the first triangle from left to right on the lower edge will increase the magic effect, but it will absorb more magic power, far more than the amount of magic effect, and the cost performance is extremely low. ”

"Summary: This formation is disorganized and cannot be studied. ”

This is the case in itself, but soon, Ke Zhou actually saw some clues, although these characters were written crookedly, and even a large distance between them would be empty at every turn, but if they were connected in some way, it seemed that they could form some kind of curve.

His fingers lightly connected to the characters, but following his inner thoughts, he didn't directly connect the smooth curves, but made a few extra turns in the open space between the characters. Almost at the same time, he threw away the parchment in his hand and rummaged through the bookshelves. Soon, other parchment papers were turned out. He couldn't wait to open them, ignoring the content on the right, and began to connect the various characters.

However, this did not go his way, and the previous order of connection no longer worked. But before he could think about it, several other connecting sequences popped up in his head, and he quickly connected the characters in this order......

Function ......

He said softly, rubbing his temples in disbelief.

"How so...... This bunch of formations is all in line with the function...... It's just that the functions that match are different. He continued to rummage and gesturing.

fifth, seventh, logarithmic, and even trigonometric functions, Bézier functions......

"The order in which the characters are concatenated...... No matter how complex the magic array is, it can be connected by one function or another...... It means ......"

He was about to continue thinking when the sound of a door opening interrupted his thoughts.

"Uh...... Are you alright?What's the matter with the parchment here?" Xiao Liu was obviously frightened by the scene in front of him, and stood there in a daze, waiting for Ke Zhou's answer.
