"Yes, we've just teamed up to destroy an avatar and a projection of the Grim Reaper." Principal Duppet nodded lightly and said to the knight. "It's because of the Grim Reaper who just arrived, his breath prompted you to wake up, right?"

Ghost Knight nodded, his helmet making an old, rusty "creak" as his neck moved.

"Your Excellency, you've done enough." Dumbledore sighed. "If your thousand-year-old perseverance isn't chivalry, who else?"

Xiwen also nodded with some emotion, and echoed: "Yes, Your Excellency Knight. Tell us your name, your deeds deserve to be remembered for centuries! ”

"My name? After all these years, I don't remember anymore. The knight shook his head slowly and said softly. Just call me the Dark Knight, I just hope I'm still qualified to keep this knighthood......"

"Of course you have that qualification, Lord Dark Knight." Principal Dipper said. "If you can really bring specific information about the last time the Grim Reaper invaded our world, maybe this information could save thousands of lives and reduce tens of millions of casualties!"

"I hope so." The Dark Knight spoke in his piercing voice, and then began to explain to the three of them about the Grim Reaper.

"From the contract mark left by the god of death in my body at that time, I can tell that he came from another universe, and it was only by chance that he discovered our world through a spatial rift. The reason for his invasion is simple, just because he wants to grab more negative emotions and increase his strength. ”

"It's ridiculous to say that human beings will always have so much suffering, and there will always be so many injustices. As a result, negativity is endless, and it is only natural that this is a vegetable garden where death can easily obtain countless powers, and it only needs to be harvested regularly. The Dark Knight recounted.

"Through the influence of negative emotions, the Grim Reaper can control those personalities who have lost themselves in negative emotions, thus making them his minions. For example, when I was grief-stricken, I was easily stricken. ”

In addition, beings such as ghosts, which mostly rely on negative emotions to generate obsessions, are also easily controlled by the Grim Reaper through emotions. Back then, the Grim Reaper pulled out an army of ghosts, and each ghost could borrow the power of the Grim Reaper through the mark left by the Grim Reaper, so the ghost army was not weak. ”

At the same time, because of the constant negative emotions in the ghost's body, the power of the Grim Reaper continues to absorb and grow, and finally a strange balance is reached between the two. The strength and weakness of the ghosts manipulated by death mostly depend on the depth of their inner obsessions. ”

The three of them glanced at each other, and they all saw the solemn color in each other's eyes.

"So, Barrow will be controlled because of the negative emotions that he has hidden deep in his heart." Xiwen was silent for a moment, and then said thoughtfully.

The Dark Knight nodded slightly, and continued, "Not only that, but the Grim Reaper is also good at absorbing life energy, and using necromantic spells on those animals and plants that have been absorbed clean of life breath, making them become the minions of other Grim Reapers. ”

"In addition to this, the Grim Reaper also has an enchantment that can suppress the flow of mana. In that enchantment, wizards were like Muggles, unable to use any magic. ”

Hearing the Dark Knight talk about this very troublesome enchantment, Xiwen couldn't help but ask:

"Is there a workaround for this problem?"

"I don't know. However, in the enchantment, it is true that you can only attack by borrowing the power from the Death Seal. The Dark Knight shook his head. However, I seem to remember that Antioch Peverell, the eldest of the three wizarding brothers, cast a spell in the Dark Enchantment, most likely related to the powerful wand he created. ”

"Roughly like this, the power in the powerful wand is pushed to the extreme, balanced with the ability of the Dark Barrier to suppress the flow of magic, and successfully allows Antioch Peverel to cast a spell in the Barrier as well."

Dumbledore's eyes narrowed, and he muttered softly, "...... Elder Wand? ”

"Dumbledore, do you know where the Elder Wand is?" Seeing Dumbledore's reaction, Xiwen hurriedly asked.

Who thought about it, Dumbledore shook his head slightly, smiled and said, "I don't know, but I always feel that the Elder Wand may be in the hands of someone we didn't expect!" ”

"And what are the other two Deathly Hallows?" Principal Dippet asked, grasping the point.

"Cadmus Peverell, the second of three brothers, invented a resurrection stone." The Dark Knight said. "It is possible to pick up all the deepest memories in people's hearts and stitch them together into a phantom of a deceased person, which is not a resurrection in the true sense, but is more likely to make the living miserable."

"So...... What is the point of the Resurrection Stone? Xiwen frowned and asked softly.

"Of course, the role of the resurrection stone is also very large." The Dark Knight continued solemnly. "It can not only dig out the deepest memories in people's hearts, but even awaken the completely hidden memories in the obsession of ghosts, so as to disintegrate the ghost army organized by the god of death!"

After a period of rest, Principal Dippert's tired face had changed a little, and he was now lazily leaning back in his chair and shaking.

"The Elder Wand and the Resurrection Stone have been introduced, so what's the use of the Cloak of Invisibility?" He asked softly. "It can't be said that in a fairy tale, Ingnotus Peverier left to escape the Grim Reaper, right?"

"Not really. Considered the smartest of the three brothers, Ingnotus Peverier didn't invent the Cloak for invisibility simply for stealth. "The Dark Knight is the right way." To be precise, the reason why this invisibility cloak can have the advantages of lightness, strong defense, and long-term use. It's because its ability is not to hide the body, but to hide the space! ”

"Space?" Xiwen was stunned for a moment, then opened his mouth wide and said in shock. "Could it be that the three of Peverell used the Cloak of Invisibility to lock the Grim Reaper in another dimension?"

"You're right, after the final battle between the three brothers and the Grim Reaper, Ingnotus Peverell took out the cloak and used the power of its hidden space to send the Grim Reaper to the other dimension where he was supposed to stay. Subsequently, the three of them sealed the Grim Reaper for thousands of years! ”

"It's kind of incredible." Xiwen accidentally thought of the invisibility cloak that was lying in the space of his pocket watch, and couldn't help but ask the next difficult question. "Your Excellency Knight, do you know how the Invisibility Cloak needs to be used to seal the Grim Reaper?"

"Yes, I was fortunate enough to see that scene, and even after more than a thousand years, I dare not forget for a moment how it was used!" The Dark Knight said firmly. "Now I just hope that the content I have memorized for thousands of years can help you something!"

"Then be sure to tell us how to use it, Your Excellency!" Headmaster Dippert, Dumbledore, and Shevin shouted in unison.
