Although Mark promised to mentor Thor, he would not waste all his good morning time on this first-level newcomer, and the second-level apprentices also had a heavy learning task, especially since they had to test in a month.

It's not so much that Mark taught Saul, it's better to say that Saul first delved into it himself, and then asked Mark when he encountered difficulties and couldn't figure out what he couldn't understand.

It's a pity that even if Mark explains, Saul is half-understood in many places and can't figure out the logical relationship at all.

Before leaving at noon, Thor made another request to Mark.

"You want to borrow that puppet doll to test your mental power?" Mark didn't hesitate, went directly to the cabinet in the laboratory, opened the cabinet door, and randomly pulled out a puppet doll from inside.

The moment Mark opened the cabinet door, Thor couldn't help but take two steps back.

Looking at Thor's vigilant appearance, Mark felt funny again, "I'm afraid, I still want to borrow it?" ”

"I'm just afraid, so I need to borrow it." Thor was careful not to let himself and the puppet doll look into each other's eyes.

Thor reached for it, and Mark casually placed the puppet in the palm of his hand.

"Friendship price, 5 magic crystals for 10 days."

"Then I'll borrow it for 2 days."

Mark blackfaced, "2 days without borrowing!" ”

Thor simply said, "I only have 3 magic crystals in my hand." ”

The current magic crystal is also what he exchanged for credits and Klee.

You can cheap friends, but you can't always cheap enemies.

In the end, Mark still took Thor's three magic crystals and warned Thor that it was okay to research, and if it was damaged, he would pay 2 credits for compensation.

Wrapping the puppet doll in layers of cloth, Thor carefully placed the doll in the pocket of his apprentice's robe.

"Take Me Away, Take Me Away......"

Thor paused, "Senior, did you hear?" ”

"Huh?" Mark had already sat back down at his desk, immersed in his research.

"No, nothing ......"

Thor clutched the pocket of his robe with one hand, as if he was afraid that something might escape from it.

He picked up the book and turned to leave the lab.

On the way back to Sita, someone stopped Thor .

Thor was familiar with her, knowing that she was a first-class newcomer at the same time as him, but forgot her name.

"Thor," the little girl looked a little shy, "I have something to tell you." ”

She pinched her clothes, her index finger twirling the top of it.

"Can you finish it in five sentences?" The girl came out suddenly, and Thor almost rushed to her.

The other party was stunned for a moment, and his expression was a little aggrieved.

"I'm sorry, I'm in a hurry."

"But I ......," the girl's eyes turned red.

Thor simply bypassed the other party, and muttered loudly, "It's over, it's too late, it's too late." ”

The girl stood stunned and did not catch up.

It doesn't seem to matter.

But Thor still couldn't get out of the aisle.

At the end of the passage, another man jumped out.

"Hey, Thor!"

This man Thor knew, it was Doze.

The newcomer who used to run after Klee and later mixed up with Duke.

This time, he wasn't followed by the unassertive Rocky.

Already since discovering that Thor's magic talent is very low, Doze has not taken the initiative to come to him for a long time.

"I'm sorry, I'm in a hurry." Thor spun around and wanted to get around Doze again.

But Doze raised his hand and directly sealed the passage.

"I'll finish it in five sentences."

Thor had no choice but to stop.

Senior Luo Kai led a group of freshmen to form a mutual aid association. It is a place where people can learn from each other and discuss with each other. This afternoon at 2 p.m. is the day of the second meeting of the Mutual Aid Society, would you like to come? ”

"Do you want money?"

"Uh, ordinary students are going to be ......"

"I have no money." Thor nodded politely before pushing Dozer's hand away and walking out.

Dolze hurriedly turned to Thor and shouted, "Klee has promised to participate today." ”

Thor stopped, looked back at Dorze's smug expression, and said sincerely, "I really don't have any money. ”

He hurried away, and finally no one stopped him.

After a hurried lunch, Thor arrived at the morgue on the second floor of the East Tower.

It has been turned into his study room, and the dormitory is just a place for evening self-study and rest.

The outermost morgue has been rearranged by Thor, and in addition to the teleportation table and two long tables, a cabinet has been added, which contains some of the necessary supplies for the experiment that Thor has exchanged.

The instruments and materials cost Thor the remaining credits.

If it weren't for the Wizard's Tower, Thor would have had to drink the Northwest Wind.

In addition to the things Thor had bought, there were also some alienated materials that he had taken from the corpse.

An accident leads Thor to discover that if the materials he took were not placed in the empty box on the long table, they would not be taken away the next day, but would remain where they were.

After studying "Grimm's Perception of Witchcraft Transformation" and "Guide to Corpse Refining", Thor already knows how to use some basic materials.

So every time he worked, if he could get more than two materials, he would leave one.

As for whether it will be recognized as stealing?

Saul didn't think so.

The book that Mentor Kaz gave him was not just to examine the residual properties of corpses.

The second half of the book is all about how to preserve the material, some simple applications, and a little bit about the soul.

Since the tutor let him study this book, he must also have the idea of letting himself learn the rest of the knowledge.

However, even the containers that Thor bought specifically for the storage of perishable materials could not prevent the corpses from decomposing naturally.

Fortunately, in the book "Corpses", there is also a mention of a Tier 0 witchcraft - organ preservation.

In order to learn this sorcery, Thor must first master the complex dark compound rune.

This is also the reason why he studies hard day and night these days.

It's just that the difficulty of this dark attribute compound rune is beyond Thor's imagination. Even though he was highly gifted in mental power, he still couldn't quickly understand the principle.

That's why he spent the magic crystal to ask Senior Mark for advice, but unfortunately although Senior Mark gave him some ideas to solve the problem, he still didn't find the right answer.

Using an absorbent pen, Thor carefully traced the basic shapes of the compound runes on a blank sheet of paper.

"Through the coordinate axis, I can basically determine that the figure I drew is consistent with the original rune. But why can't this rune be activated when it is depicted with spiritual power? ”

This compound rune is already one of the simplest compound runes.

He looked like a new pattern of two basic runes overlapping each other.

It's just that one of the runes has shrunk in proportion.

"Senior Mark said that the compound runes are not only the overlap of the two basic runes, but also pay attention to their proportional relationship. But I also divide the magic proportionally, and it still seems that something is wrong? ”

"Senior Mark also said to pay attention to the angle, what is the angle of observation?"

Thor held the white paper in front of him, eye level.

Suddenly, he had a flash of inspiration.

"Is it the perspective angle?"

Saul immediately put the paper down, took a ruler to find the center dot to draw a perspective drawing, and tried to explore the distance between the two figures by calculating the proportional relationship.

"That's not right!"

After working for a long time, he still couldn't activate this rune.

"I've calculated more than a dozen times, and I shouldn't be wrong, but it's not a perspective view."

Somewhat annoyed, Thor threw the compound runes that he had drawn into a clump and threw them into the trash.

He stared at the waste paper in the trash can in a daze.

"Where am I having a problem?"

The runes in the trash can were pinched and crumpled, concave, convex, vertical, and flat.

It was as if there were countless small runes dancing and jumping in front of Thor's eyes.

"Wait!" Thor suddenly his eyes lit up, and he raised his hand and slapped his forehead, "I have already thought that the two runes may not overlap, but exist in a spatial distance, why haven't I thought that the plane where the two runes are located is not necessarily parallel?" ”

Thor pulled out a new blank piece of paper and drew a three-dimensional axis on it.
