Hogwarts: Wizards of Eternity.

Chapter 55: Alchemical Organ, the Second Brain

The second brain in Hermione's hand is the failed product of the second-generation machine that Roger is developing after completing the first-generation machine he is currently using.

Although it is said to be a failed product, many of its functions are actually not weak. Its failure was purely because Roger discovered that there was something wrong with his research direction, so it became a scrapped project.

Just like the previous magical brain transformation.

It's not impossible, it's just that Roger has a better choice.

"Is this enough?"

Following Roger's instructions, Hermione slightly opened the collar of her wizard robe, then placed the round sphere at the junction of her collarbone and sternum, and then let it stick close to her skin.

The slightly cool touch made Hermione feel her skin tighten.

"Yes, that's it." As he spoke, Roger took out his wand and tapped it lightly.

A moment later, the round bead turned into a phantom, half of it sunk under the skin and half of it exposed. It looked a bit like... Ultraman's colorful energy timer?

【Second Brain-Start】

An illusory voice suddenly sounded in Hermione's mind.

"When the second brain is activated, it will use the power of magic to reconstruct the internal structure of your body."

"I have learned from the previous lesson between Harry and I. I have constructed a spell that can affect the sense of pain and loaded it inside. This way you should not feel too much pain during this process."

"Plus, this reconstruction is a pure magical covering effect, similar to Transfiguration, and does not involve any fundamental changes. So as long as the second brain is removed and the magic is canceled, your body will return to its original state. So there is no need to worry about the current discomfort."

"...But I still feel so uncomfortable." Hermione's face became uglier and uglier, but it was not because of pain, but dizziness.

The feeling she had at this moment was just like when she was a child and had a fever of over 39.5°, and everything she saw seemed to be spinning.

"It's normal. After all, it's making some adjustments to its perception. Your current feeling has been optimized by me. It was even scarier before the optimization."

"..." Hermione was silent.

But it wasn't that she didn't want to talk, but she was so uncomfortable that she couldn't speak.

After about three minutes, everything was finally over.

[Second Brain-Loading Completed]

The illusory voice sounded in her mind for the second time, and all the discomfort gradually faded away. At that moment, she felt that the world in front of her eyes had changed!
"What...color is this?" When he opened his eyes, everything in front of him became unfamiliar.

Not only the light, but even the wind around me became different. In less than half a second, detailed data on humidity, wind speed, temperature, etc. appeared in my mind.

She can even determine the specific length, width, area, volume and other physical properties of all the objects around her by visual inspection.

"Whether it's the three-color vision of humans or the sixteen-color vision of mantis shrimps, they are actually limited. I referred to the perception of octopuses and built a 'true color' vision for the users of the second brain... Don't pay attention to these small functions of the five senses. Try to think of 'acceleration'."

In the few seconds that Roger was talking, Hermione, who had already calculated how many hairs there were on his head, had an idea.

The world before their eyes changed again. Roger's voice became elongated, and Harry and Neville's movements became funny.

Everything around seemed to be slowed down to three times the speed.

But she was not affected by the distortion of sound and movement, and could still understand what Roger was saying. The processing power of her brain was enough for Hermione to understand everything.

"You can feel it, everything has slowed down. But this is just to overclock your mind through stimulation, not to enhance the processing power on a regular basis. It's OK to use it for ten minutes in battle, but if you exceed the time limit, it will cause great harm to you."

"In addition to mind overclocking, it also has functions such as absolute memory, tactical analysis, spellcasting assistance, self-manipulation assistance, and learning planning."

Roger looked at Harry and Neville beside him and said, "It may be difficult for you to have a real experience just by talking about it. Harry, why don't you two try to spar with Hermione?"

Hearing Roger say this, Harry also became a little interested.

Then he drew out his wand.

Hermione also raised a smile. To be honest, she had never fought with other wizards. Only Neville raised his finger and pointed at his face, a little stunned: "I hit Hermione? Really?"

There is a big gap between Neville and Hermione in learning magic.

Is this the game I am qualified to play in?
"It's okay, I'm here." Harry patted Neville on the back.

After saying that, Harry took a step forward.

According to the etiquette of wizard duels, the three stood on both sides and saluted.

Then, Expelliarmus!
A swift spell flew out from Harry's wand.

Looking at the Disarming Spell coming towards her, Hermione was not in a hurry. She was the first to arrive and raised her hand to cast a silent Armor Spell.

The Iron Armor Spell is a spell that can create a magical wall. Strictly speaking, it does not have the defensive power of iron armor, but rather imposes a layer of 'magical isolation'.

This was a difficult spell that only senior students who were about to graduate from Hogwarts would learn. Hermione had only heard of it before but had never studied it.

But this time...

She discovered that as long as she thought about it, she could cast the spell she needed with the help of her second brain.

[Assist in Casting]

This assistance function relies on the data that Roger has input into it. In other words, if Roger has not input the magic, Hermione cannot use it in this way.

The Shield Charm deflected the Disarming Charm, and Hermione followed with a flick of her wand.

'Tarantella arantallegra'

This is a kind of minor evil curse, which belongs to the curse magic system. Once hit, the person will dance non-stop.

Because it falls into the category of curse, a small amount of malice is required when casting the spell.

Originally, Hermione was not good at this kind of emotion-based spellcasting system, but after her second brain fine-tuned her nerves and hormones, allowing her to mobilize her emotions more easily, this no longer had any problem.

Self-manipulation assistance

Not only emotions, but when needed, it can be used to speed up body healing and change body appearance, which is equivalent to half a Metamorphmagus.

Of course, this kind of assistance is not omnipotent. High-end magic such as the Killing Curse and Love Magic requires intense emotions from the soul.

There was a flash of red light, and Hermione's curse was halfway through being defeated by Harry's Disarming Charm.

At this moment, Harry has not only undergone a transformation, his mental strength has increased day by day, and his magical ability has also been greatly enhanced under Roger's guidance.

One mantra has multiple uses.

Just as the Levitation Charm has the potential to manipulate matter at the microscopic level, the Shield Charm can forge a mental wall between two quarreling wizards.

Magic is not a system that converts magic power into 'welding energy' and releases it.

The mind is the foundation of magic. In theory, most spells have the ability to subvert the world as long as the caster is strong enough.

Don't be trapped by the appearance of the spell.

The essence of the Disarming Spell is "magic that eliminates the opponent's attack capability."

Aren't spells also a weapon that can hurt yourself, just like a bullet?

After a brief confrontation, Hermione and Harry stared at each other seriously.

Look for the opponent's weaknesses.

And this time.

"Petrify!" Neville's voice suddenly sounded behind Harry!
