Hogwarts, this professor is too stable.

One penny a day, ten penny a day. The rope cut off the wood, and the water dripped through the stone.

Therefore, no matter how difficult the subject is, as long as you persevere, one day the clouds will clear up.

The explorers (research dogs) in the laboratory are now passionately conquering the final step of breaking through wood and stone.

Moqil, who had conquered Legilimency, seemed to be like a salted fish in the laboratory. He couldn't get involved anywhere, and he was idle anyway. Moqil simply went to the library and Ravenclaw's reference room to search for some information about Information about the Inferi.

After asking a few Ravenclaw juniors to help, Moqil didn't have any psychological burden at all.

When it comes to research, the entire Hogwarts' excellent resources are concentrated in Ravenclaw, and it's not common for juniors and juniors to help their seniors with work. Besides, Mochir still gives Money.

In the era when Moqil traveled back in time, it was absolutely normal for graduate students to be manipulated by their bosses and senior brothers and sisters.

There are even some dirtier hidden rules.

In later generations, Moqier knew that many of his students had unspoken rules for calling beasts, especially female ones, who seemed to love playing these tricks more. Why do you say that? Because they were able to climb to that position, many of them relied on this hand. This is a story of a dragon becoming a dragon knight.

The research circle is as dark and chaotic as the entertainment industry.

Compared with them, Mochir felt that the teaching atmosphere at Hogwarts was simply the Garden of Eden, and all the professors were saints.

At least Mochir has never heard of any Hogwarts professor who is greedy for money and lustful.

The information Moqil consulted himself was "Detailed Explanation of the Magic of Dark Creatures" in the restricted section of the library. As mentioned before, this is a book that Tom Riddle borrowed when he was in third grade.

Moqil has reason to believe that the Dark Lord's understanding of dark creatures like the Inferi began here.

What is the Inferi?

The book talks about a lot, but in the final analysis, they are dead corpses, controlled through the call of black magic. They have no life, no souls and thoughts. They are afraid of fire and light, and like darkness and dampness. They are the walking dead.

According to what Dumbledore said before, Regulus is not a real Inferi.

This is actually a very strange thing.

Mochir carefully recalled that Regulus in the original book joined the Death Eaters at the age of 16, and was one of the earliest ones. But he should also be the first group of Death Eaters to betray the Dark Lord.

In 1979, in order to destroy Voldemort's Horcrux, Slytherin's Locket, he drank poison and was dragged to the bottom of the lake by the Inferi.

Before his death, Regulus gave Slytherin's locket to his house elf Kreacher, ordering it to destroy it and forbidding it to speak of him to his family.

So why did he become an Inferi? The Inferi require black magic to deal with...

What magic is involved?

Thinking of these things, Moqil's mind seemed to have a string being plucked. He stood up from the table suddenly. He stood there blankly, his eyes flickering uncertainly.

What a coincidence, these things are such a coincidence...

When many things are cleverly put together, it's as if there is a hand secretly designing all of this.

Sirius's tears, the "chandelier" that knocked him out the day he woke up, and Dumbledore's summons after he woke up.

and also……

When Principal Black asked him to help rescue Regulus, he felt the pity, heartache, and intolerance in his heart.

Why did I agree without thinking carefully?

Why could Sirius cry?

Mochir saw in his memory that Sirius did not shed a single tear when his mother tortured him with the Cruciatus Curse. In so many sufferings, Sirius only saw his best friend James. He burst into tears when he left this world. What made him cry?

And the tear happened to fall into his own hands.

Mochir almost instinctively took out the letterhead. He wanted to write a letter to his batter friend in Azkaban, and there were some things that needed to be clarified.

But almost as soon as the quill landed on the letterhead, he inserted the quill back into the ink.

Watching the ink dripping on the letterhead slowly smearing, Mochier's thoughts slowly began to spread.

A bold hypothesis slowly took shape in Mochier's mind.

What if the person behind these things was Dumbledore?

Perhaps there was some kind of life-saving magic passed down in the Black family. Regulus survived in the black lake, but the inferi around him made it impossible for him to get rid of it, and he slowly became what he is today.

On the day Quirrell attacked Gringotts, Regulus also came to Gringotts. His figure was captured by a reporter from the "Daily Prophet". After the incident, he was brought back by the house elf Kreacher. The old Black family home.

Dumbledore knew about this through the portrait of Phineas Nigellus Black, but why did he agree to help?

What was the value of an almost dead Regulus?

The biggest possibility is Slytherin's locket... and the news about the Dark Lord's Horcrux.

If that were the case, everything would make sense.

The more Mochier thought about it, the more shocked he became. Why did Dumbledore drag him in? Did he want to test himself?

For this reason, Dumbledore even went to Azkaban to find Black...

Dumbledore told Black about Regulus. If he already knew part of it, Dumbledore and Black told about Regulus's struggle against the Dark Lord, then would Sirius shed tears?

After experiencing so many separations, when he learned that his only living relative had become a half-dead "inferi", after he learned that his brother, whom he had misunderstood and hated for so many years, was such a brave and fearless person. …

Will Sirius cry?

The answer is already in the bottle of soul echo that Mochir once drank!

If this hypothesis is true, then this matter forms a closed loop, closely linked, and the sophistication of the planning involved makes Mochier feel amazing.

When Mochier was doing research, the first thing he did was to put forward a hypothesis. Although there is not much evidence now, Mochier felt that the main logic of this hypothesis was not wrong.

if it is like this……

Mochir's eyes narrowed slightly, which meant that Dumbledore might need to do a more important thing for him later.

After all, how could Dumbledore possibly "test" him if there wasn't something of greater value?

Pulling back a soul wandering on the other side of the curtain, Mochir felt that Dumbledore could do better than himself now.

Resurrecting a soul fighting against the Dark Lord and sharing the same important secret, from this point of view, is simply the stepping stone that Dumbledore has paved for Mochir to enter Dumbledore's circle.
