Hogwarts Passer-By Professor

Seeing Dumbledore's expectant look, Eisen did not hesitate, first took out the fake Slytherin's locket, and placed it on the table in front of Dumbledore.

"This is the locket found in a cave on a cliff by the sea." Eisen said.

Looking at the locket in front of him which looked a little different, Dumbledore frowned involuntarily. After reaching out to pick it up and feel it carefully, Dumbledore looked at Eisen: "It's not a Horcrux—"

"Obviously, the real Horcrux has been replaced a long time ago!" Eisen looked unchanged, took the locket from Dumbledore's hand, opened it, took out a piece of parchment and placed it in front of him.

Dumbledore's expression became serious, and after reading the contents on the parchment, he looked up at Eisen, as if he was waiting for something.

"I checked the list of wizards admitted to Hogwarts school from Professor McGonagall, and found that Rab is probably Regulus Arcturus Black!" Eisen said that he had long wanted good words.

"It's unbelievable!" murmured Dumbledore. "Reculus is a hero."

"I thought, yes! So, I went to 12 Grimmauld Place and found this—" Eisen nodded, pulling out the real Slytherin's locket and placing it in front of Dumbledore .

"The fourth Horcrux, Eisen, I have to say, you really surprised me!" Dumbledore picked up the Horcrux, his eyes flashed, and then he gave Eisen a meaningful look.

"No, if I didn't know about the cliff by the sea from you, I would never have found this Horcrux." Eisen shook his head, there is no need to take credit for it.

After coming out of Dumbledore's office, Eisen couldn't help feeling emotional. Four horcruxes have been found, and if Hufflepuff's golden cup is found now, then only the soul fragments parasitic in Harry's body will be left to deal with.

I don't know if Dumbledore has successfully developed a spell similar to astral projection.

On Saturday morning, when Eisen was eating in the auditorium, he heard many little wizards discussing one thing: Hagrid's pet Luke was bullied miserably when he was fighting a big black dog!

"I can't believe that Hagrid's pet Luke is so powerful, he dares to compete with that big black dog!" Dean's face was flushed, and his face was full of surprise.

"Although the big black dog bullied Luke very badly and ran back to Hagrid's hut in fright, Luke bravely barked at the big black dog several times at first!"

"I heard that Luke is less than a year old, I bet that big black dog is already dozens of years old!"

...

A black line appeared faintly on Eisen's forehead. If I'm not mistaken, the big black dog should be Sirius Black.

It's just that Sirius Black in the form of Annie Magus can communicate with Hermione's pet Crookshanks, so why did he fight Erharuk?

Could it be that Sirius Black couldn't bear it because Erha was too stupid?

At noon, Eisen went directly to Hagrid's hut. Only then did they discover that the trio was actually staying with Hagrid, and it seemed that the trio had come to comfort Hagrid.

"Hagrid, is there really a big black dog bullying Luke?" After Ron held Luke in his arms, a surprised expression appeared on his face.

Maybe it was because Ron had fed Luke for a while, so Luke was quiet in Ron's arms. However, judging from the pitiful appearance of it constantly licking its left front leg, I'm afraid it was really taught a lesson by Sirius Black.

"I didn't take good care of it, it's still so small, it's so pitiful!" Hagrid's eyes were red, and he seemed to be blaming himself.

"Madam Pomfrey has already seen it, and it's nothing serious." Ron pushed Luke's head away, revealing its left front leg, which had no scars.

"Harry, do you think that big black dog is the big dog predicted by Professor Trelawney?" Looking at the trio, Eisen found that Harry was in a low mood, so he asked directly.

"She was right when she said that what Lavender was afraid of was going to happen on October 16th, when Lavender's bunny, Binky, died. She said the big dog was the worst omen —” Harry frowned tightly.

"Don't worry, you're safe inside Hogwarts!" Eisen raised his eyebrows, and then comforted him.

To say that Sybill Trelawney's prophetic ability is not accurate, there are indeed many things she can be right. But if her predictions are accurate, many times her predictions are just crazy words.

According to Trelawney, one cannot take a divination class without having some sort of "vision."

In other words, when all the little wizards who took divination classes read the book "Putting Through the Fog to See the Future", what they interpreted might be different from what Trelawney read.

"Yes, Professor Eisen was right. Professor McGonagall was right not to allow you to go to Hoodmeade. No one can guarantee that Sirius Black will attack you there." Hermione said to Harry in a didactic tone.

"Have you ever thought of something?" Ron teased Luke, looking up suddenly.

"What?" Harry looked up in confusion.

"Why can third-year students go to Hodmeade, and the guardian must sign the application form?" Ron said, with doubts in his eyes.

"Maybe it's because you're worried that the lower grades will be hurt?" Harry was taken aback for a moment, and then showed an unsure look.

Hermione looked at Eisen, and seemed to think that as a professor at Hogwarts, he should know the reason! Unfortunately, though, Eisen doesn't know what it's all about.

"I don't know why, maybe it's because there are many bars in Hogsmeade, and students above the third grade can go there to drink after signing and agreeing with their guardians?" Eisen's tone was also uncertain, and he paused Then he continued, "Or maybe it's just a Hogwarts school tradition, who knows?"

Hearing Eisen's remarks, the trio looked at each other for a while.

Eisen didn't stay long with Hagrid before leaving.

In the new week, Eisen finished a class as usual, and took the trio to practice in the Room of Requirement on Saturday night.

Eisen had nothing to do for a while.

In addition to practicing spells every day at Hogwarts, Eisen will also explore various secrets in the library. In his spare time, he would go to his secret base to further study alchemy.

During this period of time, Eisen can feel his progress in alchemy, but unfortunately, his research on Horcruxes is still in a state of stagnation.

Of course, this stagnation is mainly reflected in the soul. Because of the lack of deep understanding of black magic, Eisen has made little progress in research involving the soul.

However, in the case of little progress in the study of the soul, Eisen wanted to take another shortcut, starting with memory magic, and achieving his goal through in-depth research.

The effect was beyond Eisen's expectation. One day in late October, Eisen directly developed a "Oneiroi Charm". This spell is similar to the Daydreaming Charm developed by the Weasley twins, but it works quite differently.

The daydream spell allows a person to have a high-quality daydream for 30 minutes. Although the principle behind Eisen's development of the Oneiroi Charm is not bad, it belongs to the category of memory magic, but it is a dream constructed with self-awareness and all memories as the core.

The long-term existence of this dream depends on Eisen's own self-knowledge, but because his memory is increasing every moment. So the moment the Oneiroi Curse was developed, the dream formed was evolving simultaneously every moment.

In other words, the moment Eisen developed the Oneiroi Charm, he created a dream that he carried with him. He can project his thoughts into dreams anytime and anywhere, without being limited by time and place.

Daydreaming is just the most basic function, and Eisen is also free to set up scenes, edit images, direct movies and so on. In the dream, Eisen can be an omnipotent god.

Of course, this is an extremely false god. After leaving the dream, the feeling of omnipotence will disappear.

In developing such a spell, Eisen's intention was to touch the soul through it. But later, as he continued to feel deeply, Eisen found that this path ran counter to his original intention.
