Snape, the Sunshine of Hogwarts.

Chapter 150: Problem Solving Methods
Severus deliberately brought this up with Nico in front of Grindelwald.

Even though this old man, who was imprisoned, had lost his former spirit and hadn't held a wand or used any magic in a long time.

But he is, after all, a dark wizard standing at the top of the wizarding pyramid. While Nico is analyzing things for him, what insights might he offer?

Nico took the letter written by Dumbledore from Severus, his eyes noticeably widening slightly.

He moved no differently from the other elderly people, and even seemed a little shaky when he picked things up.

He opened the envelope and, after reading the entire contents of the letter, looked at Severus with a sudden realization.

"Albus said that there are some compatibility issues between your soul and your magic itself."

That single sentence alone was enough to grab Grindelwald's attention, who was sitting on the single bed with his legs drawn up.

He turned his gaze to Severus, whose cloudy eyes seemed to see things that ordinary people could not.

"Magic and soul are incompatible?"

Facing their gazes, Severus drew his wand and cast a spell in front of them.

"Fluorescence."

A bright white light shone from the tip of the cane, illuminating the originally dim prison room.

Just from this illumination spell, it's clear that Severus is by no means weak in the application of spells.

He has too many accolades to his name—

Potions master, dark magic master, Occlumency expert, Legilimency master.
This caused other talents to be overshadowed by these overly impressive aspects.

For example, as a pharmacist, Severus was also quite skilled in herbal medicine. Although he was not as skilled as Sprout, he was still among the top herbal medicine experts.

There is also Defense Against Dark Magic.

As an expert in dark magic, he naturally understood how to resist such dark forces better than the average person; otherwise, he wouldn't have been so persistent in trying to obtain the position of Defense Professor at Hogwarts.

As for spells, needless to say.

During his student days, Severus secretly invented many useful curses, poisons, and even spells.

For example, [Tongue-Sealing Throat Lock], [Upside-Down Bell], and the most powerful [Divine Sharpness Without Shadow].

Who is so kind as to not graduate from Hogwarts and then create their own spells?

This is the only one of its kind in decades!
It's estimated that only students like Dumbledore and Riddle could rival Severus.

But neither Grindelwald nor Nicole, who are here right now, are ordinary people.

Especially Nicolas Flamel, although he is now very old and his strength is nothing to speak of, his knowledge and experience over the past few hundred years are unmatched.

Upon seeing Severus use the Illumination Charm, he astutely noticed the problem.

“A perfect spellcasting.” Nicole stared at Severus’s wand. “It’s impeccable in every aspect, and the effect is perfectly matched to the current level of magic, but…”

"But as Albus said in the letter, the spell itself is not the problem, but it is clearly not in line with your own soul when it is cast."

His gaze shifted from the wand, and he began to look Severus up and down.

“This situation is extremely rare. Only some magic that affects the soul can cause it. However, those magics almost always weaken the soul. In all my years, I have never heard of any magic that can strengthen the soul.”

Grindelwald was also staring at Severus, but he didn't speak; he was observing silently.

At that moment, Nico raised his wrinkled and spotted hand, and a small silver alchemical snake appeared in his palm, coiled around his wrist.

"Heh, they used me as a threat to get Abel to do some things, but thankfully it's all right and hasn't been hurt."

The silver snake, which the elders of the UMNO called an "earthworm" and which Nico named "Abel," crawled from Nico's hand onto Severus's body. The snake slithered along Severus's arm and finally reached the top of his head.

"Relax, don't be nervous, it won't hurt you."

After Nico's reassuring voice rang out, a drop of blood-red liquid flowed from the little snake's mouth!
The liquid dripped onto Severus's forehead and quickly seeped into his skin, eventually disappearing without a trace.

Afterward, Severus clearly felt his body become lighter.

That wasn't an illusion; it actually happened.

This drop of potion seemed to possess a life force far exceeding that of any magic potion, giving Severus a sense of vitality throughout his body, like an old tree sprouting new leaves!
"This is... the elixir of immortality?"

The instant he sensed the change in his body, Severus guessed what the drop of potion he had just absorbed was. Aside from the legendary elixir of immortality made from the Philosopher's Stone, there was absolutely no other potion in the world that could achieve such an effect.

"The trace amounts of immortality elixir absorbed through the skin can temporarily activate your body and freeze you in that moment."

As Nico explained to Severus, she pointed at his body with her wand.

"When the body is activated by magic, yet simultaneously frozen in place, the changes in the soul become more apparent."

He spoke in a very soft voice, while his eyes widened as he observed Severus!

"Merlin's pants!"

"My soul is wearing Merlin's pants?" Severus quipped.

At this moment, even Grindelwald seemed to have noticed something, and he too was staring at Severus.

“His soul and will are very strong,” Grindelwald said.

“Very powerful! I’ve never seen such power among wizards!” Nico raised his voice, and the silver light shining from his wand kept falling down, like solid pieces of light.

"But the stronger it is, the more wrong it is! This shouldn't happen to a wizard at all, because an overly powerful soul causes reason to dominate the mind, while emotion and feeling are at a disadvantage."

Nico spoke loudly, but then couldn't say what he meant to say.

Grindelwald stared at Severus, his eyes unblinking, and gave the answer.

"This shouldn't be the soul of a wizard."

“Yes!” Nico stared intently at Severus. “Normally, you wouldn’t become a wizard at all! You’d be a Squib, or if you were from a Muggle family, you’d be a Muggle!”

Upon hearing their conclusion, Severus's expression remained unchanged, but Ghost Snape's eyes widened.

It took him a long time to fully process the news. He stared at Severus in utter shock, as if he were seeing him for the first time!
Severus was not at all surprised by their discovery; he simply inquired about another meaning behind Nico's words.

"What are the criteria for a Squib? In a wizarding family, only ordinary people who can't use magic can be called Squibs? If both parents are Muggles, their child could still be a Squib?"

Nico seemed somewhat surprised that Severus would suddenly pay attention to this issue, but he still patiently explained.

“Wizards are born from magical genes. If their parents are Muggle wizards, and you trace their family lineage back, there must have been wizards among their ancestors.”

"The so-called Squib is specifically someone who has magical genes but no spellcasting ability. If both parents are wizards or one parent is a wizard, then of course they can be identified and called Squibs. But strictly speaking, everyone in the world who has magical genes but no spellcasting ability should be called a Squib."

"For example, some wizards have Muggle parents. Since they can give birth to wizards, it means they have magical genes. It's just that they don't come into contact with the magical world, so they are not called Squibs, but Muggles."

At this point, he fixed his gaze on Severus.

"Those who have magical genes but lack the ability to cast spells, such as Squibs, have many reasons why they cannot cast spells, but a small portion of them are due to their souls being too powerful!"

"A powerful soul isn't a good thing either?" Severus clearly didn't have much knowledge about the human body or alchemy.

Nicole shook her head.

"Magic is inherited from magical genes, while the soul is unique to each life. Magic grows stronger as a person grows. If magic is not released in the form of magic frequently, but is suppressed, it will become an Obscurus."

"But there is one special case: if the soul is too powerful, a person's thinking will lean towards rationality and focus on logic. In the Muggle education system, such people are basically geniuses in science. They have extremely strong logical reasoning abilities and are very sensitive to numbers."

"However, for wizards, excessive rationality and logical thinking are completely anti-magical. In such people, even if magic power continues to grow, it will be suppressed by the powerful soul, and they will not be able to cast spells or become Obscured, thus resulting in Squibs."

Severus understood what Nico meant.

And what he said was absolutely right; before he transmigrated here, he did indeed have the best grades in science subjects.

Magic, however, is clearly contrary to reason.

Of all magical knowledge, apart from potions and alchemy, which might have some connection to logical thinking, the other related subjects make absolutely no sense.

Basically, it's "the power of my thinking".

This is why Dumbledore always emphasized the power of love, but never told Harry to study math.

Mathematics can't work magic, but true love is indeed invincible!

The problem has now been identified, and Severus was already aware of it. He was a Muggle who had transmigrated into Severus Snape's body, so it was normal for his soul not to match that of a normal wizard.

So what's the solution?
