After He Youyou went out, a figure followed closely behind.

"Teacher He, I want to take a long vacation in the remaining months and study at home and not come to school." Su Yuluo said to the teacher with some anxiety at the entrance of the stairs.

Looking at the beautiful face and firm expression in front of him, He Youyou was very impressed. Is this the monster who rejected two top universities in a row? It is indeed a good student I taught.

"I have heard of your legend. Classmate Su, come on, don't put too much pressure on yourself. As long as you are sure, you can study by yourself in the remaining few months and you can't use it for school." At this moment, He Youyou's voice was particularly gentle.

"Yeah, thank you teacher, I will continue to work hard!"

Looking at the girl who was constantly moving away, He Youyou seemed to see the self who resolutely chose the ghost-type elf despite the opposition of his family. The same persistence, the same persistence, and the same beauty.

The elf ball vibrated, and the dream demon felt the uneasiness in his trainer's heart, as if comforting her.

After returning to the classroom, in everyone's surprised eyes, Su Yuluo packed up her things and walked out of the classroom with her schoolbag on her back.

In fact, she was not the first student to choose to go home to study. Many students from other classes from good families made the same choice. It was just that He Youyou's class was quite special. The students were a little afraid of the teacher who raised ghosts, so no one mentioned it.

In fact, Teacher He is usually a very kind teacher. She never corporally punishes students. For those students who make mistakes or do not listen carefully in class, she usually just lets them sleep. After a few minutes, the students will be pale and wake up in cold sweat.

It is much better than those teachers who are punished and run away at any time, but this has led to no one in Class 1 in three years to sleep in the classroom because you don’t know if you will be awakened by a nightmare next moment.

As soon as he returned home, Su Yuluo put down his schoolbag and ran to the training ground excitedly. At this time, Leo Road and the Arctic Dragon at the Tail of Staff were both in the training ground.

"How is it, what is it? Is it successful?"

Before the person arrived, Su Yuluo's screaming sounded in his ears. Looking at her cheerful look, Bai Ziyi knew that the little girl's leave seemed to have succeeded.

After waving his hand at the little girl, Bai Ziyi continued to study. Just now, the actual drill of the first ultra-electromagnetic cannon move failed, and he was thinking about a solution.

When the little girl saw Leolu's thoughtfulness, she immediately understood that this attempt must have failed. She was careful and did not choose to disturb Leolu at this time, but turned on her phone and found out the relevant electromagnetic knowledge and read it.

In Leolu's current long-range move system, the main thing is to rely on wave missiles of various attributes for output. Although the newly learned vacuum waves are released at a very fast speed, their power is limited and they are OK, but they play a limited role in fighting powerful elves.

Therefore, the pillar of Leo Road's long-range system is wave missiles. Although wave missiles have variable properties and are powerful, they are enough to deal with most opponents.

However, in recent battles, wave missiles have also exposed their serious shortcomings, that is, their flight speed is average, explosive and lack sufficient stability and penetration. Just like a bomb, it is easy to be detonated directly by the opponent halfway, thus unable to play its due role.

In order to make up for the loopholes in this long-range system, Leolu needs to learn a fast, stable and penetrating long-range move. Originally, Su Yulu wanted to further develop vacuum wave moves, but she was attracted by the ultra-electromagnetic gun moves described by Leolu, so she gave up her previous plan and instead developed ultra-electromagnetic gun moves with Leolu.

Therefore, she is quite familiar with the principle of Leolu's ultra-electromagnetic gun. At this moment, she began to search for the notes she discussed before, hoping to find out the reasons for the failure.

In fact, Bai Ziyi combined the relevant content of the anime in his previous life and the relevant knowledge in this world to roughly confirm that Misaka Mikoto's super electromagnetic gun move should use the principle of a coil cannon or a magnetoresistive electromagnetic gun.

In the anime, every time Mikoto Misaka fires, round after circle of electric arcs will be wrapped around his arms. These arcs act as coils, making a powerful induced magnetic field around his arms. Under the action of the magnetic field, the iron coins in his hand will move forward at high speed as if they were attracted by magnets.

This is the principle of the super electromagnetic gun deduced by Bai Ziyi. Logically speaking, as long as he can also control the current to spiral forward on his arm, the super electromagnetic gun's move should be done. When it comes to use, it is nothing more than bringing a few iron marbles, or using steel energy to condense into small needles.

But the first attempt failed, and the difference was the energy control. After all, he was not an electric elves and had limited control over electric energy. The only long-range move he knew now was the Thunder Wave missile, which only needed to pour the electric energy into it, without too much fine operation.

Now, this super electromagnetic gun not only requires controlling a large amount of electrical energy to generate a strong magnetic field, but also needs to carefully divide this large amount of electrical energy into arcs and move forward in a spiral shape on the arm from near to far. Isn’t this difficult for a strong elf?

Therefore, this super electromagnetic cannon move was stuck at this most critical step. Bai Ziyi was unwilling to give up, and was thinking about the solution to this step.

"Liolu, isn't it possible to be the energy spiral step?" Su Yuluo asked after looking at the notes for a while.

Bai Ziyi nodded and raised his arm, trying to rotate the electric energy around his arm, but just after it was released, the small arc immediately spread out to the surroundings, and was not obedient at all.

"Isn't it okay to spiral directly in the body?"

Bai Ziyi shook his head again, spread his hands, and looked helpless.

After understanding where the problem was stuck, Su Yuluo began to search for relevant knowledge purposefully. The key to the problem now is how to generate a movable magnetic field under the simplest situation. As for external control, it is too unreliable and is not what Leo Road should consider now.

Looking at the two apprentices who were thinking hard at the same time, the tailed scaly armor dragon touched his head speechlessly. What should I do if I think about this kind of brain-related thing?
