After binding the comprehension system, I crossed into Hogwarts

The Hogwarts Train is a red-skinned train transformed from a Muggle train.It looks old, but it has been modified and reinforced by many great magicians, and is regularly maintained by the Department of Magical Transportation. Its overall safety is very reliable.

Therefore, the only ones attacking them were the invisible dementors, and no Death Eaters carrying black magic sneaked in.Now, according to Lupine, after detecting the anti-Apparition curse, Kingsley Shacklebolt and his colleagues activated the train's own defense array, which can more effectively resist outside invasion.

"Then how does Senior Sister Tonks get in? Can she drive away all the dementors here?" Sun Zhu asked what she was most confused about. Currently, there were some frightened juniors in No. 6 and No. 7. Fina and Karina were there to take care of them.She and Lu Ping went alone to the connection between the first and second carriages. Not far away was the sightseeing corridor, but there was no one there at the time.

As far as she knew, wizards did not have any effective way to kill dementors and could only use their patronus to drive them away.

The dementors are so lethal, yet they are willing to serve as guards in Azkaban. They even obey orders when necessary and go out to hunt down escaped suspects. This is all because the Ministry of Magic promised that they can feed on suspects imprisoned in prison. All positive emotions, but no harm to innocent people.

They are called soulless demons, but their most irresistible nature is appetite - all positive human emotions are their food source.Although they cannot be killed, any wizard who knows the Patronus Charm can drive them away, which often leaves their appetite unsatisfied.So a certain Minister of Magic reached a cooperation with them, which has been mutually beneficial for hundreds of years.

Let the most terrifying and vicious dementors guard the most vicious criminals. It's not like fighting fire with fire.

But now that the Dementors had defected so early, it was beyond her expectation.

After all, they are a group of things with no IQ and no morals. In the original book, after Voldemort was resurrected, he promised that they could suck other people's positive emotions at will, and they would naturally rebel against the Ministry of Magic.But now it was just a group of Death Eaters, and it actually attracted such a large number of Dementors to follow them and flee.

"Raising tigers is a danger. Will the Ministry of Magic let them see criminals in the future?" Sun Zhu sighed, "But these are all things for later. What can Senior Sister Tonks do?"

"We don't have a way to eliminate them, but we have a way to severely injure them." Lu Ping explained, "They will actively absorb the happiness and other positive emotions of the humans around them, and suck the souls of all creatures that have lost the ability to resist. This is an uncontrollable instinct. Dementors are also essentially magical creatures. Padfoot's new magic item research team has created a batch of experimental products with contaminated souls. As long as Tonks brings them here, the Soul Eaters will take the initiative to suck them. It will weaken them as if they were poisoned, and then they will have to leave."

"The souls that have been polluted..." Sun Zhu was a little surprised, "Where did they come from?"

"The batch of 'experimental products' provided by the Department of Magical Disasters should be the troublesome magical creatures they collected from various places. Bigfoot gave them a large sum of money, and they contributed all of them..." Lu Ping explained, "Similar to spotted mangosteens and Billywig bugs. The Department of Magical Creatures was originally responsible for recycling and processing them, but Padfoot said he had other uses, so..."

Sun Zhu nodded: "I know, they are actually raw materials for potions, but do they also have such a thing as a 'soul'?"

Lu Ping smiled confidently: "Everything has a spirit."

Sun Zhu was stunned by these words, and then quickly reacted: "I understand, then, the most important thing is, how did they become 'contaminated', and when did this..."

She suddenly thought of something and looked at Lu Ping and blinked: "It can't be..."

Lu Ping looked out the window, then nodded: "Yes, it was Padfoot's experiment some time ago. At first, only a batch of test subjects with 'contaminated souls' were harvested. Later, it was determined which components could 'annihilate the soul' .”

Sun Zhu then looked out the window, which was still shrouded in darkness, and the ice flowers on the window glass showed no signs of diminishing.She crossed her arms and began to think about the thousands of wonderful uses for the basilisk venom, and whether she should add a chicken drumstick to it when she went back.

but……

"Is it possible that Sirius has already caught Dementors and tested them? Otherwise, how could he be sure that these contaminated test products would work on them?"

"No, of course not." Lupine chuckled, "But he has been tortured by these things in Azkaban before, so he understands them. Anyway, there is nothing to lose by trying."

Why do you think this is what the big black dog likes to say? Professor Luping must have been infected by him.

"Then let's treat the dead horse as a living horse doctor. After all, this bus is still moving forward. Just drive them away early, and the people on the bus will be less tortured. I think the situation of several junior students is already very bad. alright."

Lupine nodded slightly, his eyes full of worry: "I'm going to check on the students again. Please help Tonks here."

Sun Zhu thought about the dozen or so people still at the front of the car and sighed worriedly.

She was the only idle prefect at the moment, the others were either trapped or taking care of other students.Just now, Senior Sister Bernice sent a patronus over to say that several new students from the Muggle world had already started crying, saying that they had never seen such a dangerous school, and that they could encounter such things just by taking a bus to school.

This Dementor really brought Hogwarts to shame.

"Bang bang bang!"

A loud noise came from outside the window glass. Sun Zhu followed the sound and saw a big, powerful-looking bird standing on the outer edge of the glass, knocking on the window with its wings.

When the train activated its own defense array just now, all the windows were closed and could not be opened manually.

She called out uncertainly: "Senior Tonks?"

The big bird tilted its head towards her, and Sun Zhu saw that there was a large package on each of its paws, but he couldn't hear its words clearly through the glass.

"Host, that is indeed your target Tonks. If you want to hear her words clearly, just open the [Quest Identifier]." Tongzi reminded.

"Sweat, I haven't used it for so long that I forgot about it."

With Tongzi's plug-in, she quickly understood Tonks' instructions: "Quick, the yellow package in my hand is a potion prepared by the St. Mungo's pharmacist. A student has been approached by a dementor at close range. Yes, use this for them! Inside the black package are weapons to deal with them, Sirius gave it to me, I have to go ahead and try it out."

Sun Zhu pushed the window glass hard with his hand, but found that it didn't help.After thinking again and again, she could only pull out the exquisite "hairpin" in her hair, which was the magic prop that Tongzi had rewarded her with.
