Hogwarts wizards who signed in to Middle-earth.

Chapter 343 The Black Death Plague
After guessing the identity and purpose of the infiltrator, Dui, Gandalf, and Galadriel all increased their surveillance of the school.

The other professors at the school also learned that the school had been infiltrated by the enemy, and they were all on high alert.

The deans of the four colleges are responsible for the students in their respective colleges and prohibit students from acting alone. Other professors also patrol the castle constantly.

Portraits were hung in every corner, serving as human surveillance cameras to ensure that there were no blind spots in the castle.

The atmosphere at the school suddenly became tense.

The students looked bewildered, not knowing what had happened, only that the professors had become very serious ever since the last Quidditch match when the brooms broke apart.

But no matter how confused or curious they were, they obediently followed orders. Apart from class time, they stayed in their respective dormitories and common rooms during their free time, and even when they went out, they went in groups of two or three.

Even the mischievous Pikachu sensed the tense atmosphere and became much quieter.

Moreover, as the spirit of the castle, he is aware of many things within the castle.

So when he found out that it was that person in the shadows who caused all this, he was furious, feeling that the person in the shadows had ruined his chance to play a prank.

So he angrily vowed to catch that lurking rat and teach it a lesson.

So he often roamed through the castle walls, specifically to catch those sneaky students, and even secretly hid in areas where the portraits couldn't monitor him, such as the toilets.

Seeing a student sneaking around, he would suddenly jump out from the wall or toilet, grab the student's nose, and shout, "Gotcha! You little mouse, you can't escape Mischief's eyes!"

Although in the end, all the students caught by Pikachu were proven to be just students who wanted to steal food and play, and there were no suspects.

But the mischievous ghost's actions successfully calmed down the naughty students and even forced the person in the shadows to temporarily back down.

The only thing the professors couldn't understand was what kind of thought process some students had when they secretly ate in the toilet.

Even Dui was speechless after hearing this.

As for Angerber, the first-year student who was supposedly bewitched by the Ring of Power, Dui only deducted 50 points from his academy as punishment for picking up the ring randomly, and then sent him back to the academy.

Furthermore, it was not disclosed that the dismantling of the broom at Phoenix Academy was done by Angberg; instead, points were deducted for Angberg's violation of school rules.

After all, although Angber was bewitched by the ring, he did do this and almost killed a student from Phoenix Academy. If this were made public, it would not only make Angber a target of public criticism, but could even trigger a conflict between the two academies.

Dui also investigated Angbo's roommates and classmates to see if Saruman might be hiding among them.

After all, the ring was clearly sent to Angbor by Saruman on purpose, which was very likely done by someone he knew.

But in the end, there was still no result. None of Angbor's roommates and classmates were tainted by the dark aura, nor were they possessed or touched by the Ring of Power.

Dui was not disappointed that no trace of the enemy was found.

After strengthening surveillance of the schools and placing Gandalf and Galadriel in charge, Duy accelerated the creation of the Marauder's Map on his own.

With the help of vitality potions and the Crown of Wisdom, Dui worked day and night, making rapid progress.

Saruman, who was hiding in the shadows, seemed to sense that something was wrong.

Just as Dui was nearing completion of the Marauder's Map, another incident occurred. When Edward hurriedly knocked on the principal's office door, Dui had a bad feeling: "Something's happened?"

Edward nodded, panting, "It's three students from the Dragon Academy. Professor Gandalf and Lady Galadriel have already arrived and would like to ask you to come over as soon as possible!"

Hearing Edward's anxious expression, Dui didn't bother to ask for details and hurriedly left the office to go to the scene of the incident.

The accident occurred in the kitchen. When Dui arrived, he saw three second-year students lying on the floor, with Gandalf, Galadriel, and Magdalene, the headmaster of the Dragon Academy, nearby.

In mid-air, Peeves was happily tap-dancing, waving a Quidditch bat and muttering cheers, "Peeves caught the murderer!"

Upon seeing the three students lying on the ground, Du Yi's pupils contracted. Without even greeting the others, he quickly ran forward and knelt down to examine them.

When Dui realized that all three were still breathing, he breathed a deep sigh of relief.

Then it was discovered that two of the three students had been afflicted by a stun spell.

The remaining one had a large, obvious bump on the back of his head, as if someone had hit him from behind with a stick.

"What exactly happened? Gandalf, Lady Galadriel?" Duy asked, looking up.

Gandalf shook his head. "We were just a step ahead of you. When we arrived, the scene was exactly as it is now. All three students were already lying here. But you can ask Peeves about that, since he was the first to discover this place and immediately had the portrait sent to inform us."

Upon hearing this, Dui looked surprised and looked up at Pipi Ghost, asking, "Pipi Ghost, what exactly happened? Can you tell me?"

At the same time, seeing the bat in Pippi's hand and recalling the student who had been knocked unconscious on the ground, he had some guesses in his mind.

Upon hearing Dui's question, Pipi Ghost immediately puffed out his chest and said in an exaggerated manner:

"Oh my, that was terrifying! Those three kids from Dragon Academy sneaked into the kitchen, and I followed them quietly. I never expected to witness such a frightening scene!"

He pointed to the student with a large bump on the back of his head, "Principal, let me tell you, this kid is the bad guy! He brought those two kids into the kitchen, and then used a spell to ambush the students from behind, knocking the other two to the ground!"
His eyes were terrifying! I hid behind the wall, only daring to peek out! And that rascal even secretly took out a black bottle of medicine, intending to pour it into his dinner and drinks, but I knocked him unconscious with a single blow!

"Hehe, Principal, didn't Mischievous Ghost do a great job? You caught the bad guy!" Mischievous Ghost proudly sought praise.

A black medicine bottle? Dui's expression hardened. "Where is the medicine bottle?"

"Clang clang clang! Headmaster, look!" Mischievous Ghost hopped and skipped as he pulled out a small black bottle. "Mischievous Ghost could tell at a glance that this was no good, so he snatched it from the bad boy immediately!"

Just as Duy was about to reach out to take it, Gandalf and Galadriel's expressions changed, and they warned him warily, "Duyel, don't touch it!"

Upon hearing this, Dui immediately became alert and used a levitation spell to catch the black vial.

He looked at the black potion in the bottle, then turned to the two men and asked, "Gandalf, Lady Galadriel, do you know what's in this bottle?"

Galadriel stepped forward, her deep eyes fixed on the bottle. After carefully sensing what was inside, her voice became very solemn.

"This bottle contains the Black Death plague! A very evil virus!"
