I made science magic

Under Linn's constant urging, Jonny nodded, quickly took out the notebook in his arms, turned to the latest page, pointed to the title on it and asked. "Professor, what did you say today?

I'm not very good at plane rectangular coordinate systems...especially this question..."

"If you want to judge the distance between two coordinate points, you need to use the Pythagorean theorem mentioned before. You can mark the difference between the horizontal and vertical coordinates on the coordinate axis, and then connect them together with a line.

Doesn't this turn into two right triangles joined together, so it's back to the problem of geometry..." Linn explained to Jonny the idea of ​​​​solving the problem in a simple and easy-to-understand manner.

The so-called doing business is naturally to start a small stove!

After all, Lin En had previously promised that as long as he could pass the exam, he would apply for graduation in the name of the professor. Too many people passed the test, and too many applicants were eventually rejected by the council. Of course, the content of the exam should be as difficult as possible.

However, this difficulty is also limited. It is impossible to teach some knowledge points that have not been taught before. At most, the question types are just a little bit more difficult... a little bit!

In order to ensure that Jonny can answer all the questions correctly, it is essential to do a small job.

Although it is somewhat unfair to other students, it is not a shameful thing to ask a professor for tutoring.

Lin En never prohibited other apprentices from asking him questions, but Jonny asked more and more deeply.

Two hours passed in a blink of an eye. Jonny closed the notebook in his hand, raised his eyes to look at Linn, and said with a smile: "Thank you for your guidance, Professor. I have to say that you are really a great person."

teacher!"

There was a faint blush on the girl's cheeks, and she looked at Lin En in front of her with bright eyes. She seemed to have been completely immersed in the academic exchange just now!

"I just came into contact with the Mathematical Olympiad earlier than you." Lin En shook his head.

No matter how early it was, it was only half a year ago. Jonny rolled his eyes at him, and he finally understood why the eyes of the ordinary class students were filled with envy, jealousy, and hatred when they looked at them. This gap in talent

It's simply despairing.

"Then I won't disturb you, professor, and we'll see you tomorrow." Jonny put away the notes filled with answers and problem-solving ideas and prepared to leave.

Linn stood up and sent the witch to the door. Before leaving, the silver-gray-haired witch looked at the knuckles of Linn's left hand as she opened the door and said with a hint of emotion.

"I didn't expect that the teacher would even give you this."

Linn paused for a moment, then followed Jonny's gaze and looked down. On the ring finger of his left hand was Ladak's [Ring of the Faceless Man].

Kelu is actually a member of the Faceless Men...

Lin En was greatly surprised. This was completely beyond his expectation, but his face remained calm. "Teacher, he cares about this ring very much? Do you know how to use it?"

Jonny shook her head. She only knew that Keru had taken this ring with her when he accepted her as an apprentice. She guessed that it was a very powerful alchemy tool, but it had never been used in front of her.

After the silver-haired witch left, Linn closed the door and looked at the [Ring of the Faceless Man] in his hand.

Could it be that Kelu revealed his identity?

But wasn't this guy captured by the Holy See and taken to the Holy City?

As long as he was not tortured severely and burned on the stake, the possibility of escaping was slim.

Or maybe Kelu mentioned himself to someone before he was arrested by the church.

[No. 4 hasn’t been here for a long time, right?]

Lin suddenly thought of what one of them had mentioned when attending a gathering of faceless men. Could it be that Number Four was referring to his mentor Kelu?

…

In the evening of the next day, in front of a luxurious manor in the southern part of Ietta Harbor, three convoys pulled by camel beasts slowly stopped in front of the door.

Linn, who had already disguised himself, walked out of the carriage in the appearance of Ladakh. Naturally, he was here to participate in the so-called promotion ceremony.

Lin En also came with Ladak's fifteen apprentices. Bock, Patty and others were both looking forward to it and excited. They hoped that they would be selected this time, so that they could reach the sky in one step and become a noble official.

wizard!

"Master Ladak, please come!" The sturdy guard at the door opened the closed iron door and invited him very respectfully.

Lin En led a group of apprentices into the gate of the manor and walked toward the interior of the manor along a path paved with cobblestones.

Behind him, the sturdy guard had already sealed the iron door again, looking at everyone with a mocking look on his face, but he failed to notice that dozens of small, dark-looking rats were passing through the crowd.

Coerced by him, he quietly slipped into the manor.

These rodents are naturally puppets controlled by Linn using the psychic technique [Necromantic Control]. Their small size is not easily noticeable. In addition, there are several gray crows and more secretive geckos.

Although they don't have much combat effectiveness, they can serve as his eyes to observe the layout of the entire manor and the surrounding environment. If necessary, the liquid bombs they carry may also come in handy.

After passing through a long corridor, Lin En and others arrived at the banquet hall of the manor. The interior was very spacious, and a variety of exquisite delicacies and desserts were placed on the long table.

At this moment, many guests have gathered in the banquet hall. It is roughly estimated that there are only one or two hundred people. Most of them are apprentices, but there are also many formal wizards. Barbara and Hank are among them. Linn even saw Ietta.

Sheriff Leia of the Harbor.

There were more or less smiles on their faces, and they were talking among themselves, and the atmosphere was quite harmonious.

On the stage in the center of the banquet hall, a valet in a tuxedo was dancing an elegant jazz dance. The pretty maid held a silver tray and served drinks and meals to the guests at any time.

"Radak, why are you always the last one to arrive?" Hank saw Linn entering the door at a glance, stepped forward, and gave him a light hammer on the shoulder.

"Coming early is worse than arriving well, isn't it?" Lin En looked around at the lively scene in the banquet hall and responded casually, then lowered his voice and asked. "Are you sure North will come to this gathering?"

In the past few days, Linn also tried to control the gray crow to search for traces of North, but there was no gain.

"Since he has not canceled this promotion ceremony, he will definitely come!" Barbara said decisively.

As soon as Barbara finished speaking, North, wearing a gray robe, appeared in front of everyone...
