Chapter 1368 Gretel: Oh No, the Teacher Is Here to Check the Homework!

Grete leaned against the tree outside the door and sat for three full hours before he saw the light door on the tree trunk open for the second time.

The Lord of Thunder floated out, moved casually, and the next moment he was on the ground, waving to Gretel.

Behind her, Princess Norrell said nothing, her eyes were slightly red, but she looked at the Lord of Thunder with joy and tenderness in her eyes.

Gretel breathed a sigh of relief:

Fortunately, it seems that the teacher is not exactly a straight man of steel - no, he is a straight man of lightning.

Uh, no, lightning is originally folded one after another, or bifurcated. It is not born to go all the way to the end!

Let’s talk about the magnetic lines of force built around the electric field, which are even more arc-shaped...

While thinking wildly, he stepped forward in small steps.

The Lord of Thunder looked him up and down and saw that the young disciple's aura was full and lively, and his mental power was pure and pure. It was obvious that he had advanced smoothly, so he nodded with almost imperceptible satisfaction:

"The spell you wrote in your paper uses magnetic field changes to observe the human body. How did you come up with it?"

Grete almost blurted out, "The MRI is written in the book, not what I thought." When the words came to his lips, he quickly bit them and suddenly raised his head to look at the teacher:

wrong!

This doesn't feel right!

Teacher, are you trying to trick me? !

"It's still sensitive to the influence of mental power, not bad." The Lord of Thunder nodded slightly, with a little more satisfaction in his eyes.

When he asked the question just now, he casually used a little mental shock and confusion method, for no other reason than to test his little apprentice's mental power.

Now it seems that although he has not practiced any special spells, he has a kind of natural acumen, and he reacted without saying anything -

Maybe it's the instinct after blending with nature? No matter what the reason is, in short, if you are sensitive enough and mentally strong enough to not be confused, that would be great!

Grete sweated silently. The teacher looked calm and made it clear, "I'm just a tester, so what?" What else can a disciple do...

How can you escape from the teacher's door even if you can't be beaten and can't be scolded?

In addition to expressing sorrow and accusation with his eyes, he could only think quickly and come up with the excuses he had prepared before to use to excuse the teacher:

"Isn't this? When we were doing experiments before, it was too troublesome to explore the inside of the human body... [Detection Magic] is too expensive and cannot be seen clearly by ultrasound, so I wanted to use a new method... After trying it a few times, I found that the magnetic force seems to be Can……"

"Try it for me."

"ah?!"

"Try to show me." The Lord of Thunder simply stopped. At this time, they happened to come to a small clearing with green grass and a meandering stream that merged into a half-moon-shaped pond.

There were no houses to the left or right, and no one was around. It seemed that even if the magic failed, it probably wouldn't affect anyone else.

"But teacher..."

"Just give me a rough demonstration and let me see how far you can control it." The Lord of Thunder said slowly.

Grete glanced at him quickly, then looked at Princess Norrell next to him, and was surprised to find that with the princess around, the teacher's tone was much gentler than usual——

He used to give orders directly! One word at a time, absolutely decisive, never tactful!

It's so rare... Maybe you want to show your softer side in front of women who like you, so as not to scare them away directly?

In that case, as a disciple, you have to save face for the teacher.

If the things produced are ridiculous and outlandish, and make people feel that the students' standards are too low, the teacher will lose face, and his competitiveness in chasing girls will also be weakened...

Grete swallowed, took a deep breath, and calmed down. Touching his pocket, he took out a mouse tail from the space bag, walked into the grass, and placed it on a stone by the pond.

Then stretch your hands forward, clasp each other, and pull them apart little by little. The four fingers of your left hand are curled up with the thumb upwards. The five fingers of your right hand are spread out, and the fingertips should be kept at the same distance as much as possible——

The left hand points forward, the fingertips sparkle with lightning, and a silver-white lightning rises steadily, circulating between the palms of the fingers;

With his right hand, he carefully plucked the tailbone of the mouse a few times like a plucked instrument. The invisible force stirred up a little ripple and quietly passed through the mouse's tailbone.

"Probably, that's it... But the signal of what I made is very messy and complicated, and basically can't be seen clearly, so I can only ask the teacher to take action..."

Grete put down his hands, turned around, and reported to the teacher in a polite manner. By the way, he really tried his best to make it look like this...

In the previous generation of nuclear magnetic resonance, there were too many conditions and algorithms required to obtain reliable signals. Don't say he doesn't know. Even if he knows, he can't tell. He can only hope that the teacher will figure it out on his own...

The Lord of Thunder kept staring ahead, with various runes and lines flowing rapidly on the blue monocle. When his disciple turned around, he hummed softly and took two steps forward with his hands behind his back:

"The level of controlling lightning is still too low. Is this a six-ring lightning chain? Your senior sister can already control a seven-ring lightning spell into an extremely stable one at your level!"

"Yes, I will practice hard in the future..."

Gretel lowered his head in repentance and cursed in his heart: Teacher, Senior Sister Philby, she specializes in thunder and lightning spells, and controlling her to this level is the proper meaning of the question.

I specialize in medical treatment, and I only use electrical magic for one purpose. You ask me to reach her level, which is too high!

"If electricity is not strong enough, magnetism is not strong enough. If you cannot spread a strong enough magnetic field, you cannot smooth out the original magnetic influence in the world, and the results will be interfered with."

Gretel suddenly raised his head, met the Lord of Thunder's eyes, and then nodded repeatedly. That's right, the reason why nuclear magnetic resonance requires a strong magnetic field is to eliminate interference from external magnetic fields——

Unexpectedly, the teacher even felt this!

"If you want to spread a strong enough magnetic field, you need to be at least eight rings - if you don't have enough control, you need nine rings."

Well, the eighth ring is actually right in front of him. If he advances one more time, he can theoretically use the eight ring magic. So, he is almost able to do a hand rub MRI?

Grete looked at the teacher expectantly. The Lord of Thunder snorted noncommittally:

"As for the control of the magnetic field, it is really bad, not even as good as a five-ring mage. You have to make up for these basics."

Gretel lowered his head and was speechless. The Lord of Thunder half-turned around, his eyes fell on Princess Norrell, and his eyes quickly softened:

"It's a joke for you. I still need to study this spell carefully, and the two little guys also need to give you some guidance. Then, I'll take my leave now -"

"Can I come visit?"

Princess Norrell subconsciously took a half step forward. The Lord of Thunder smiled and nodded:

"welcome any time."

As he spoke, he waved to Grete, who couldn't help but fly up with him, into a ball of white flowing clouds, and flew down the mountain. Sitting on the clouds, I heard the Lord of Thunder ask:

"When we get to your place, show me what you learned and how well you learned it."

Gretel: ...Help!
