Summary: The male protagonist is always wrong

Hermione found a new use for the notebook Yin Li gave them for Christmas. She wrote all her review notes in the notebook so that Ron and Harry could review together.

Ron saw this and thought Hermione was absolutely crazy.

Yin Li watched their interaction and smiled.

Reviewing didn't require much effort for him, and since he didn't have to study potions, he could only spend his spare time on alchemy.

He thought that this kind of day would continue until the exams were over, until Snape sent him a letter for the first time.

Come to my office tonight!

There was only this one sentence in the letter, and Yin Li always felt that he was going to be scolded again, but he hadn't done anything recently.

He knocked on Snape's office door after dinner.

"Come in." Professor Snape's tone didn't seem so angry.

So what exactly happened?

Yin Li pushed open the door and walked over. Snape was standing in the middle of the room looking at the little white mouse in the cage.

Rats are usually kept in the potions room. Is there anything special about bringing them outside?

Professor Snape stared at the little white mouse without saying a word.

Yin Li looked at his expression and asked tentatively, "Professor, is something wrong?"

Snape said calmly, "The rat drank your bottle of oracle essence and produced magic."

Produced magic power? Yin Li frowned when he heard this.

This little white mouse has no magic powers, it is just an ordinary animal.

Like a funnel with no bottom on either side, its initial mana value is 0, making it very convenient as a test subject for mana potions.

No matter how many mana potions you feed it, its magic power will eventually run out and return to 0. It cannot store magic power or generate magic power on its own.

The oracle essence that Yin Li had made at the beginning, which was the bottle that was confiscated by Professor Snape, had the effect of enhancing magic power. Logically, it was useless to the mice because 0 multiplied by any number would be 0. But now it had transformed from an ordinary creature...

"It became a magical creature," said Snape.

Yin Li certainly knew what this change meant. He asked, "What did you do to it? Oracle Essence shouldn't have this effect."

"It drank the latest mana potion. During observation, the remaining magic may have allowed it to escape, knocking over your so-called oracle essence, and becoming like this."

Snape's expression wasn't ugly, but it wasn't pretty either.

This potion was too amazing, and he was not ready to release it to the public.

All Muggles can become wizards, which is horrible.

What would the world be like if this thing were actually invented?

"Professor, the material of the oracle essence is not easy to obtain, or even very difficult to obtain, and I only have one copy." Yin Li reminded.

The little white mouse accidentally turned into a magical creature, it was really all luck.

Whether this luck can be replicated is a question.

The potion hasn't even been developed yet, but you're already considering its impact on the world. To be honest, this is a bit of an unnecessary worry.

Even if it is really developed, its materials will not allow it to become a common item on the street.

Snape stared at the mouse in silence.

Yin Li continued, "The ingredients used in that potion come from a tree called 'Dachun'. 'Xiaoyaoyou' says: 'In ancient times, there was a Dachun tree, whose eight thousand years were considered spring and eight thousand years were considered autumn.'"

Snape frowned at this.

Yin Li took out a bottle containing dark brown powder. "This is the powder made from the core of the fruit, and I only have this little bit left."

"Isn't it possible for your mysterious oriental family to get some more?" Snape paced around the room anxiously.

He saw glory beckoning to him, he was about to create a potion that would shock the wizarding world, and he would explore a new world.

He couldn't stop now.

No Potions Master, no Slytherin could remain calm at this moment.

But he had to calm down, because he knew that this honor did not belong entirely to him, but most of it belonged to his student, an 11-year-old Ravenclaw.

Perhaps this 'indifferent to fame and fortune' Ravenclaw wouldn't even make this potion public.

Snape stopped and waited for Yin Li's announcement.

"Even if there is, it won't be too much." Yin Li said calmly.

With only this little material, is it possible for them to replicate that luck?

"If you want to try it, then please." Yin Li reached out and handed the last material in his hand to Professor Snape.

Professor Snape didn't reach out. He snapped, "You need to understand what you are doing."

"I've always been clear. I believe you're trustworthy."

Yin Li looked into Snape's eyes seriously.

At this moment, their fate is shared.

Snape moved, but instead of taking the material, he turned and walked back to the Potions Room. "We have to find out what's going on."

Yin Li looked at the materials in her hand and put them away first, then followed him into the potion room carrying the cage of the little white mouse.

Snape waved his wand, and the potion room seemed to be playing in reverse, with time moving backwards rapidly.

He paused at the moment when the little white mouse drank the magic potion and remained unharmed, and then watched the whole process of it turning into a magical creature again.

Yin Li saw it bite through the bars of the cage and crawl out. Then it did not choose to run down, but upwards, it jumped onto the cabinet.

It smashed various potions along the way, then knocked over the bottle of Oracle's Essence.

The poured potion mixed together, the little white mouse licked a few times, and then started chirping. It seemed to feel uncomfortable all over and began to roll on the ground.

Professor Snape came back and saw the mess in the potions room. He was about to teach the culprit a lesson, but when he raised his wand, he saw the surrounding objects shattered by the magic shock.

The little white mouse was still rolling on the ground, completely unaware of what it had done.

Yin Li looked at the cage in his hand and poked it with telepathy, "Hello."

"Hungry... so hungry."

"Professor, it's hungry. I'll go get it something to eat."

Professor Snape gave him an impatient look and waved his wand to give it some nuts.

Yin Li opened the cage and put the food in, "Eat."

The little white mouse started eating and then fell asleep peacefully.

Professor Snape had already started studying the mixed potion.

Yin Li took a look and saw that it was a mysterious blue, the same color as the starry sky.

"We have to figure out its composition first," Professor Snape said as he set up the crucible.

The research did not go smoothly, and the two even experienced several explosions.

Yin Li suggested that they should take a break because the exam was coming soon and Snape also had to prepare the materials for the exam.

Yin Li has been feeling a little drained lately, but fortunately the exams ended smoothly.

After the test, Hermione anxiously ran over to him and asked, "Did you choose A for question 17 of the Charms test? I'm a little worried."

Yin Li was startled by her, but nodded, "Yes."

Ron felt a little desperate when he heard that they were still discussing the test paper after the exam.

Seeing that Hermione wanted to continue answering Yin Li, Harry immediately said, "You don't seem to be in a good mood recently. Why don't you come with me to the Black Lake to relax?"

"Okay." Yin Li agreed immediately.

Yin Li quickly fled and disappeared from Hermione's sight.

Only after they had walked far away did the two of them slow down.

"Sometimes I'm really afraid of her passion for learning." Yin Li said with a wry smile.

"Ron and I have been quite scared," Harry said helplessly.

The grass around the Black Lake is lush green. Today's weather is neither good nor bad, just an ordinary cloudy day. No students are in the mood to come for a walk as they have just finished their exams, so there are few people around.

Harry looked around and it seemed that he and Yin Li were the only ones there.

The two of them were alone together, and he suddenly felt a little nervous after realizing it.

"Um, what have you been busy with recently? Can I ask?" He started to talk awkwardly.

"Of course, it's nothing important. Professor Snape and I were working on a potion, and it wasn't going well so I was a bit distressed."

"Researching potions?" Harry didn't expect such an answer. He couldn't even make potions 100% successfully in Potions class, but Yin Li was already researching potions. He felt a little disappointed. "I'm sorry I can't help."

Yin Li smiled at him and said, "It's okay. You've already helped me a lot by listening to me complain."

Harry didn't feel comforted at all.

Like him, Yin Li had no contact with the wizarding world before coming to Hogwarts. Now the gap between them is getting bigger and bigger. Harry urgently wants to do something to bridge the gap between them.

Yin Li also noticed that his mood was a little off, "Harry, are you okay?"

He looked at Harry worriedly, "You don't have to think so much. Don't put too much pressure on yourself. Some things are not your responsibility."

Yin Li thought he was worried about the Philosopher's Stone.

Harry shook his head. "I'm fine."

Chapter 89 Harry Potter 10

The rumor on campus was that Harry Potter had defeated Professor Quirrell and stopped him from stealing the Philosopher's Stone.

Harry was sent to the school hospital because of his injury, and his fans gave him a lot of gifts.

Madam Pomfrey from the hospital wing told everyone not to disturb Harry.

At night, Yin Li turned into a ghost and sneaked into the school hospital to see him.

There was no one else in the hospital wing, and Madam Pomfrey had gone to rest.
