Little Red Star's "Mind Refresh"

According to the panel's introduction, Little Red Star could not only let him experience life in the magical world of "Harry Potter," but also activate the "Mind Refresh" function, strengthening his brain's ability to learn, comprehend, and remember.

Of course, the panel did not specify exactly how much stronger it could make him. He would have to experience it himself to find out.

Now, he felt that if he relied on his own abilities to study, even if he put in two hundred percent effort, he would be lucky to barely learn even the simplest spell in a month.

So, if he wanted to have decent combat ability before returning, it would be crucial to spend Little Red Stars to activate the "Mind Refresh" function.

"Grrr!"

Rubbing his growling stomach, Jerry looked at the darkening sky and decided he could properly test Little Red Star's "Mind Refresh" function after dinner.

"Crookshanks, let's go have dinner!"

Jerry rose from his chair and was about to call his first pet, Crookshanks, to dinner with him when he realized that Crookshanks, who had been snoring away on the bed, had already vanished without a trace.

"Uh, it didn't run away, did it?"

He searched under the bed, inside the trunk, and in the cabinet, but could not find Crookshanks anywhere. Jerry could only scratch his head helplessly.

Come to think of it, he had been too absorbed in his reading just now. He had barely noticed what was happening around him.

"Whoosh~~~"

Just then, Jerry suddenly felt a cool breeze blow against the back of his neck, making him shudder.

He slowly turned around.

Crookshanks was standing outside the window at some point. Cleverly, it had used its paw to pry the window open a crack, squeezed through the gap, and then shut the window behind itself with a casual swipe of its paw.

That cool breeze had come in when Crookshanks opened the window.

"Meow!"

Crookshanks eagerly ran over to Jerry, dropped the thing it had been carrying in its mouth onto the floor, then pushed it toward Jerry with its paw.

It looked as if it were saying:

"Today, I am your master. This is food your master has bestowed upon you. Hurry up and eat!"

"Crookshanks, I... thank you!"

Jerry's mouth twitched slightly as he looked at the dead rat pushed to his feet.

No wonder that witch had said Crookshanks was so easy to keep, to the point where there was hardly any need to prepare food for it.

After dinner,

Jerry sat down at the desk again and reopened "Magical Theory."

"Use Little Red Star!"

The moment he activated the "Mind Refresh" function on the panel, Jerry sharply sucked in a breath.

He felt a stream of cool energy suddenly pour directly into his brain through the Baihui acupoint.

His brain, which had grown increasingly sluggish after a busy day, instantly returned to peak condition after being infused with that cool energy.

It felt like waking up in the morning after eight or nine hours of deep sleep and downing a glass of cool boiled water.

His mind was incredibly clear, and his brain exceptionally active!

Lowering his head, Jerry resumed studying "Magical Theory." He found that all the obscure and difficult magical theory from that afternoon had suddenly become much simpler.

It was as if advanced calculus had turned into a simple linear equation after using Little Red Star's "Mind Refresh" function, dropping several levels in difficulty in an instant.

Or, more accurately, his brain's comprehension, learning, and memory abilities had improved by several levels, making difficult calculus seem as simple as a linear equation.

With the boost from "Mind Refresh," Jerry's reading speed through "Magical Theory" suddenly increased dramatically.

That afternoon, he had spent more than four hours barely getting through four or five pages, and he had not even fully understood them.

But now, with "Mind Refresh" boosting him, he got through a quarter of "Magical Theory" in just one hour, and had almost completely understood and absorbed it.

"Stop!"

Four hours later, after Jerry had finished reading the entire "Magical Theory" and committed it all to memory with a full understanding, he temporarily turned off the panel's "Mind Refresh" function.

Without the "Mind Refresh" boost, his brain returned to its normal state. At the same time, an intense wave of exhaustion washed over him.

"Looks like using Mind Refresh not only consumes Little Red Stars, but also seriously drains mental energy. I should buy a few cases of Six Walnuts to keep on hand!"

Only then did Jerry realize that while the "Mind Refresh" function was incredibly powerful, it also placed a considerable burden on his body.

He hurriedly closed the book, got into bed, and in less than two seconds, he had fallen into the deepest level of sleep.

The next morning,

When the first ray of sunlight shone through the window onto Jerry's face, he slowly opened his eyes.

After a night of deep sleep, his brain had returned to normal once more.

"I can't use it for so long at once next time!"

Since it had been his first time using it yesterday, the state of "Mind Refresh" had felt so wonderful that he could not help keeping it on for four whole hours.

Although he had finished and understood the entire "Magical Theory" in one go, his brain had also been overdrawn, and he had entered deep sleep almost immediately afterward.

So, keeping the "Mind Refresh" function on for such a long time was clearly unwise.

Overusing his brain would make his body instinctively enter deep sleep, because deep sleep could restore his brain more effectively.

But while in deep sleep, he would not react even if thunder exploded outside. That meant that in such a state, he would have absolutely no vigilance.

If danger came, he would be a lamb waiting for slaughter.

Opening the panel, Jerry checked how many Little Red Stars had been consumed after activating "Mind Refresh."

"Two hundred and forty? So that means one Little Red Star per minute."

He had activated the "Mind Refresh" function for a total of four hours last night and consumed two hundred and forty Little Red Stars. That worked out to one Little Red Star per minute.

Overall, it was acceptable and not too far beyond what he had expected.

He had originally had one thousand and five Little Red Stars on his panel. After spending two hundred and forty yesterday, he had seven hundred and sixty-five left, enough to activate the "Mind Refresh" function for nearly thirteen more hours.

Based on his experience of taking around four hours to master "Magical Theory," the remaining three books, "Standard Spells, Beginner," "Beginner's Guide to Transfiguration," and "Dark Arts: A Guide to Self-Defense,"

could probably all be finished quickly in roughly thirteen hours as well.

In other words, the number of Little Red Stars he had now should barely be enough for him to use the acceleration effect of "Mind Refresh" intermittently over the next two or three days and complete what had originally been a month-long study plan ahead of schedule.
