The unspeakable pain made Filch's old body twitch like a medium electricity.

The expression on his face was distorted, his eyes were pushed to the limit, and his eyeballs were covered with dense bloodshots.

The green tendons on his neck burst out, looking extremely hideous, and there was a burning sensation like jumping into magma all over his body.

He opened his mouth and howled loudly, trying to vent the pain he was suffering.

Even so, Filch's consciousness was still very awake under the mage's deliberate protection, which meant that he couldn't even be unconscious now.

It's not that Lu Wu deliberately wants to torture him, but that the subject needs to stay awake the whole time.

In this way, driven by the instinct of the body, the energy that breaks into his body will be guided to where it should go.

After Lu Wu's observation, the Squibs who were born in a wizard family are most likely to have wizard blood, but due to special reasons, the magic power flowing into their bodies cannot form a closed loop under various obstacles.

This may be the reason why these people are unable to cast spells.

To put it bluntly, it is really possible that the bloodlines in the body are too complicated, and it happens to be somewhat similar to the concepts of those pure-blood wizards.

What Lu Wu has to do is to use a huge external force to remove these obstacles in Filch's body, so that the mana can circulate smoothly.

Of course, this is just an experiment and there is no guarantee of success.

In fact, this can also be done simply through arcane particles, or the remaining two runes with relatively peaceful power.

At first he wanted the storm to gather, but the pain was the same anyway, so it was better to use a more aggressive scorching to make the experiment complete as quickly as possible.

Perhaps, while reducing the length of the experiment, it will also bring some unexpected benefits to Filch.

Ten minutes later, the first experiment was over, and the mage stopped the energy output and took his hand away.

The janitor, who had lost his support, immediately fell to the ground, still howling.

Fortunately, the mage had cast a mute spell in the office in advance, so that the loud sound could only echo in the small office, otherwise, it would definitely attract people.

Filch screamed for a moment, then fell unconscious, lying motionless like a dead corpse.

The face of the mage next to him couldn't help but show a touch of joy.

The experiment was a success.

It wasn't until a few hours later, when the sun was setting, that the poor janitor woke up.

The first thing he said when he woke up was, "Am I dead?" ”

But the residual pain on his body and his almost torn body kept reminding him that he was still alive.

Years of painful experience have given Filch a tenacious character, and if it were put on someone else, he might have to go to the hospital for a few days, and he just got back on his feet.

And asked weakly, "Sir, has your experiment been successful?" ”

The mage sat in his chair, leisurely savoring the pot of tea he had just brought from Dumbledore.

"It's our experiment, Filch the Wizard."

"I think you can feel the changes in your body now."

The janitor, who had been reminded by him, immediately felt a searing force flowing through him.

That's magic, a magic that's different and more majestic than ever!

Just because Squibs can't successfully use magic doesn't mean they don't have magic in their bodies, but the number is negligible.

Therefore, when Filch felt the magic in his body, which was thousands or hundreds of times stronger than before, he immediately burst into tears of excitement.

His lips twitched, and he wanted to say something thankful, but he couldn't.

In the end, he had to kneel on the ground, keep kowtowing to the mage, and hit the floor with a bang.

"All right, Argus, get up." Lu Wu put down the teacup and held him up with his magic.

"You're going to be a wizard too, please don't do such unseemly things."

Filch, who stood up again, seemed to have completely forgotten the pain in his body, and said with tears in his eyes: "Thank you, sir, I really don't know what to say." ”

"Then don't talk about it." The mage got up and patted him on the shoulder: "When you go back, don't rush to use the spell, just rest for a few days." ”

"Seven days later, come back here and we'll do a second experiment."

"Still coming?" Filch resisted, he really didn't want to experience the pain a second time.

"Yes." The mage patiently explained, "With your current situation, you can only play a few small magic tricks at most. ”

"Don't you want to master more powerful magic?"

Filch replied without thinking, "When... Absolutely! ”

"Then what else is there to say?" The mage opened the door to his office: "If there are no other problems, let's go back and rest first, I still have things to deal with." ”

"Oh, okay." Before the janitor could react, he was pushed out of the door by a gust of wind.

Then, the office door was slammed shut.

Even though he was ordered to be expelled, Filch did not feel insulted, and instead thought that a real wizard should be so neat and unobtrusive.

So, he bowed respectfully to the door before turning to leave.

Lu Wu, who stayed in the room, took in Filch's movements, but did not say anything.

Because in his head, he is thinking about something else right now.

Dumbledore had just called him to the Headmaster's office, and the two had a conversation.

The cause was that Lucius Malfoy had complained about him earlier today.

The reason given is very high-sounding, saying that Lu Wu does not give lectures according to the normal teaching progress, but uses some crooked ways to lead the minds of the crooked little wizards.

As a result, he is not suited for the position of Defence Against the Dark Arts professor.

And Lucius Malfoy, as one of the trustees of Hogwarts, should not have such a thing from happening.

Therefore, this arrogant pure-blood wizard decided to gather the remaining board members in a few days to discuss the expulsion of Lu Wu.

Cornelius Fudge, Minister of Magic, will also be invited.

In fact, to put it bluntly, it was because Lu Wu turned his son into a sheep that Lucius wanted to take the opportunity to take revenge.

Even if Dumbledore was the headmaster of Hogwarts, he was unable to do anything because he had to be restrained by these school directors.

However, although he could not prevent the school board from holding a meeting, he was able to reveal the news to the mage in advance.

He believed that the strength of Ez was enough to deal with such a small scene.

If you can't do it, open another arcane class and let Ruiz be the professor of this class.

As for Lu Wu, he was not worried at all, he was worried that there was no reason to trouble this group of stubborn pure-blood wizards, but he didn't expect that someone would take the initiative to send it to the door.

And among the several pure-blood families, the prestigious Malfoy family.
