Just a Defense Against the Dark Arts Professor

Seeing the last sentence in the note, Sherlock became a little silent.

This was obviously a note left by the original owner's mother, Sally Forrest, and the date it was written should have been just before her accident.

At this time, her thinking should still be normal. After completing what was mentioned in the notes, she turned into a madwoman.

Sherlock silently picked up the notebook on the desk and started reading from the first page.

"Looking at Sherlock at this time, I feel that he is the continuation of my and Victor's souls. Having a child is something that can make all women crazy with joy. I think I have always been the saneest among wizards. That one still feels like he is filled with happiness."

"While taking care of the newborn Sherlock these days, I thought about the time when I was tortured by the Cruciatus Curse, which caused cracks in my soul."

"In order to create the magic of soul repair, I studied a lot of magic information about the soul. Although in the end I failed to achieve final success due to the lack of "thread" material. But regarding the knowledge of the soul, I feel that I have already taken the lead. At the forefront of the magic world."

"The more you know, the more you will feel how insignificant you are in front of the endless knowledge. The soul is an extremely complex subject. Very few magics have conducted in-depth research on the soul, but every magic has It’s all about the soul.”

"The birth of Sherlock made me want to pick up research in this area again. The soul is undoubtedly a powerful force. I think I can use this power to give Sherlock a gift, even if something unexpected happens to me in the future. Now, this thing can still replace me and be by his side all the time."

The first few pages looked like Sally's essays. Then she built this underground study under her home, put all the soul-related books she had collected over the years here, and began to study soul magic. .

As long as there is a magic experiment, there must be an experimental subject, and the experimental subject Sally chose is none other than herself.

Sherlock's mother is obviously a cruel person. Her own soul is already divided, but she still has no scruples in conducting various unstable magic experiments on her own soul.

She wanted to use the power of her soul to create a magic that could protect another soul from harm.

Because all spells in the magic world can be related to emotions.

To use the petrification spell, you must first have a strong desire to petrify the opponent.

When using Apparition, you must firmly believe that you will reach your destination.

To use the Death Curse, you must have extreme darkness and the most decisive murderous intention in your heart.

These are all emotions that the wizard himself must think from his heart and express.

This is why wizards rarely have rational, logical thinking abilities.

Most of the time, they cast spells under intense emotions, and sensibility has become their habit. Often being in a rational state will damage their magic level.

And since the body is the basis of living, where do all human emotions and desires come from?

The answer can only be the soul.

If a person loses all desires and emotions, even if his body is still alive, he is essentially the same as dead.

For example, a dementor's kiss essentially sucks away all the positive emotions of the wizard, turning the kissed wizard into an empty body. Even if the heart is still beating and the blood is still flowing, it is still a human being. dead.

That's why it is said that there are very few magics related to the soul in the magic world, but basically all magic is related to the soul.

Since magic is all formed by the soul and ultimately affects the external reality, the soul must also have the ability to block all these influences and avoid the effects.

The other curses are easy to say, but the most critical one is the death curse that directly targets the soul.

There are only three of the three unforgivable curses because in the entire magical world, these are the only three most vicious curses that have not been cured.

The other two curses, the Cruciatus Curse and the Imperius Curse, are not completely fatal in themselves, but the Death Curse can be said to be a nightmare for all living creatures.

The effect of this spell is to be directly reflected on the human soul. The hit creature will die directly from the soul level without any damage to the body surface.

And on a magical level, no spell can be resisted or broken except physically.

If Sally's idea works, then the soul protection magic she envisions can resist even the Death Curse!

To this end she conducted many experiments.

In the experiment of the Death Curse, she naturally did not continue to use her own soul as the experimental subject. Instead, she found many rabbits and mice, and used these creatures with not powerful souls as preliminary experimental materials.

Sally's talent in magic is extraordinary. After a long period of research, she actually figured out a method of soul protection magic.

"...the rabbit numbered A132 finally survived. This is a surprising discovery and proves that the direction of my research is correct and feasible."

"However, rabbit No. B341, who was protecting the soul of A132, died. In essence, the power of the soul was not used to save the life-killing curse. It can only be calculated that one life is worth one life."

"When the Death Curse hits and is protected by the soul, the number A132 shows signs of rebounding. This is somewhat similar to the Iron Armor Curse. It may be my thinking when designing this magic, and it is also the reason why I am biased towards the Iron Armor Curse."

"And the surviving number A132 also showed some resistance to magic."

"Well, these are important experimental data. After collecting them, you can keep a copy in the Hogwarts library, just like the soul repair magic last time."

After that, Sally continued to improve the soul protection magic, and finally entered the experimental stage of human body.

This time she also did not find anyone else, but continued to use her own soul as the experimental subject.

Soul magic can finally avoid or rebound the effect of the death curse. It has been confirmed in animal experiments, so the subsequent experiments will not be so fatal.

Sally discovered that if humans want to use the powerful soul protection magic here, the caster needs to have extremely strong emotions towards the person being protected.

And this emotion must be positive, which is simply love.

Whether it is fatherly love, maternal love, or love, if you want your soul to protect the object you are protecting, you must have strong love.

If there is no such feeling, then this magic will not be effective.

If the magic is successfully cast, the souls of the protector and the protected person will be connected together. Even if the protector dies, this soul protection magic will still have an effect on the protected person.

After all, this is protection at the soul level, and this world is a world of ghosts and the dead.

Even death caused by the Death Curse will not directly destroy the soul of the deceased, but will be imprisoned in the murderer himself.

Therefore, as long as the soul protection magic is successfully released, even if the protector dies, the spell will not be cancelled.

Finally, after completing the magic completely, Sally connected her soul with Sherlock's soul, forming a soul-protecting pact.

This was also her last gift to the original owner.

After studying this magic, she left Sherlock's side, and when she appeared again, she should have become as crazy as she did later.

Sherlock finished reading the experimental notes and felt extremely complicated.

The mother of the original owner is absolutely great. She said that she is not a qualified mother, but she has made all her efforts to protect the original owner.

But in the end, the original owner died. He did not die under someone's magic, but fell down from a building during a self-defeating magic experiment, hit his head on the ground, and died.

This kind of damage does not involve the soul, it is just a simple physical damage, and the soul protection magic will naturally not be effective.

Then Sherlock arrived and took over the body, causing the protective magic to think that the soul of the original owner had been damaged and caused division.

Then he led him to find the "Soul Repair" magic hidden in the restricted book section of the Hogwarts library.

Later, the soul of Sherlock who had traveled through time was stitched together with the unconscious soul of the original owner through the thread kneaded by Riddle. Now the original owner and Sherlock are actually inseparable from each other.

Sally's soul protection magic not only protects the original owner, but also protects Sherlock.

Sherlock stood there, looking at the experiment diary in silence for a long time, and finally sighed.

At this moment, he suddenly remembered something.

In the first part of Harry Potter, the Philosopher's Stone, which he had only read completely in his previous life, Harry's mother Lily used the magic to protect Harry when she faced Voldemort's death curse, and the soul that Sally researched. Protection magic is very similar!

And Sherlock still remembers that when Harry asked Dumbledore what the scar on his head was at the end, Dumbledore told him that it was your mother's love.

Isn't this the prerequisite for soul protection magic to be used?

The protector needs to have a strong love for the one being protected!

Sherlock stood there blankly. Since this magic was invented and researched by Sally, how did Lily learn it?

There is no mention of the name Lily Evans in the experiment logs.

When magic was invented, Lily should have just attended Hogwarts and would not have been exposed to such advanced magical knowledge.

After Sherlock discovered this problem, he read the diary from beginning to end again, and finally focused on this paragraph that he had seen before but didn't care about.

"Well, these are important experimental data. After collecting them, you can keep a copy in the Hogwarts library, just like the soul repair magic last time."

When the experiment was in progress, Sally went to the Hogwarts library and made a backup copy of the research materials there!

Sherlock had a look of surprise on his face.

Then it is very likely that Lily found this magic from the Hogwarts library, then learned it, and finally bound herself to Harry's soul when he was born!

Afterwards, Lily was hit by the Death Curse and fell down first, but Harry relied on the power of protective magic to deflect Voldemort's spell, and finally survived and became the Boy Who Lived!

Everything is connected!

No wonder when he asked Dumbledore, Dumbledore said that the crescent moon mark was her mother's love for him.

Soul protection magic is indeed magic that can only be used with love. Once it forms protection, it can even rebound the life-killing curse!

Sherlock finally silently put the experiment log back to its original place on the desk. He did not take anything away from the underground library.

Everything in this study is filled with a mother's love.

In the end, perhaps because of other things or other people, she became a lunatic. She abused and spurned her son, and failed to fulfill her responsibilities as a mother later on.

But she is still a great mother!

When Sherlock was looking at the experiment diary and meditating, Amy seemed to see that his heart was heavy. She didn't make a sound on the side, just blinked and waited quietly.

The sky was gradually getting darker. At this time, little Sherlock had already returned home from school. The nanny hired by his father Victor also came here to prepare dinner for him.

But none of them noticed that there were two more uninvited guests underground in this courtyard.

Before Sherlock came to the underground study, he locked all the doors again, and there was no trace of anyone coming in the house.

The entrance to the study is also very hidden in the garden, covered by weeds. As long as you don't walk directly here, no one will notice it.

After reading all the experiment logs, Sherlock took Amy out of the underground study.

He glanced at the warm yellow lights lighting up in the house, and had no intention of taking a look at the current little Sherlock. He directly held Amy's hand and used apparation to return to London from here.

In a remote alley, the two figures appeared instantly.

Sherlock stood here to straighten his mood a little, and then took Amy with him to fulfill his previous promise and go for a big meal.

They went to a Muggle restaurant that Kingsley had taken Sherlock to before. Sherlock originally just wanted to try it, but he didn't expect that this restaurant had opened fourteen years ago.

Amy's appetite is very small, but being able to eat out, especially seeing the night view of London, is a very novel thing for her.

After dinner, they did not go back immediately. Sherlock bought Amy a colorful windmill and walked with her on London Bridge.

Amy was lying on the guardrail, holding the windmill with one hand. The wind blew the windmill and also blew the blond hair on her forehead.

Sherlock looked at the Thames River under the bridge and was filled with emotion. It seemed that he had gained nothing from this trip, but in fact he gained a lot.

He turned to look at Amy, and the flashing neon lights reflected on her face. It could be seen that she was very happy now, but the corners of her mouth still did not curl up, as if she didn't know how to smile.

Sherlock stretched out his hand and pinched her face, helping her smile, while speaking softly.

"This world is a beautiful place, Amy. There are people we love and people who love us, so remember to smile more."
