HP: After binding to the strongest wizard development system

During the past few days of resting at home, Thiel had a very fulfilling life. She spends most of her time in the study room, and with the help of the study room, her study time has doubled and her efficiency has been greatly improved.

In her occasional free time, she and Harry would sit on the sofa and eat snacks, or sneak to a nearby small park and swing together under the large shade.

There would be at least one adult left in the house, and the other would either take care of the family estate or go to St. Mungo's to see Elcott.

Till also went to St. Mungo's two or three times. Mr. Elcott, who once held a high position in the Department of Magical Law Enforcement, showed special kindness to Till.

In the afternoon of that day, Till carefully wrote down the potion knowledge in her mind in her notebook. It was basically taught to her systematically by Salazar, so when she wrote it down, it was clear and not messy.

As he wrote, Thiel lamented the incompleteness of today’s historical records.

If Till hadn't actually come into contact with the four founders, who would have imagined that the "notorious" Slytherin was a well-deserved Potions Master? Thousands of years ago when conditions for potions were scarce, his research on potions was actually ahead of today's magical world.

I really don’t know why such an important historical fact has not been recorded.

"The deepest potion must involve the illusory but real individual soul. A good enough potion master can use soul-related potions to affect and even control other people's souls..."

With Till's memory, she could easily reproduce every word Salazar said word for word, but the more she wrote, the more serious she became, and her expression became more and more serious.

Only when it really started to involve soul potions did Tyr understand the horror of a potion master.

The Dark Lord, who puts everyone in the magical world in danger, is said to like to use the Imperius Curse to control others to do things for him, but soul potions that can control other people's souls are obviously more terrifying.

The soul-stealing curse can be resisted, as long as your will is strong enough, but no one can resist the soul potion, not even Salazar himself.

Thinking of this, Titil, who was just about to write down a few soul potion recipes, paused. Salazar taught her more than one soul potion, from healing the soul to controlling the soul. I believe no one in the world knows more than she does.

But, does she really want to write it down? Is it really unlikely that someone would accidentally get hold of her notebook and use it maliciously?

Till stared at the tip of the quill and struggled for a long time. Finally, following his inner uneasiness, he did not write down any formula for soul potion.

Although everything is uncertain, and she doesn't want to think so badly of others, it's better to be cautious than to take chances.

[Host, there are several bottles of soul potion in your luggage, which were brewed by Professor Snape. ] The system suddenly reminded, [The soul potion, like the wolfsbane potion, will also become ineffective. 】

The more precious the potion, the more "bad temper" it has. Wolfsbane potion counts as one type, and soul potion counts as one type, and soul potion obviously has more "bad temper" than wolfsbane potion.

Till recalled it carefully before remembering that she had put the suitcase containing the soul potion at the bottom of the cabinet.

She quickly went to dig out the box and saw that the soul potions carefully packed inside had all turned as transparent as water. They had obviously expired and could no longer be used.

This made Tiel a little regretful and a little angry that he had forgotten such an important potion.

Till knew about the existence of these soul potions. In the days after she first returned, she fell asleep every day. When she woke up in the interval, Mrs. Emery talked about Professor Snape's contribution and hard work.

Even an excellent potions master like Professor Snape was tortured enough when he came into contact with soul potions.

Although he almost summoned Tier back when his soul was unstable due to his lack of experience, this small mistake cannot negate his efforts.

It's just that Teal was groggy for the past few days and closed his eyes again shortly after opening them. Mrs. Emery helped pack the luggage he brought home. Professor Snape's bottles only appeared in front of her once. She had long forgotten about the soul potion she had used twice.

Tier couldn't help but scratch the side of his face. If he had known better...

[Such a good soul potion, if the host sells it before it expires, he will probably get back a lot of gold galleons. 】The level 5 system has some attributes of being a money addict without any teacher. 【Professor Snape only accepted a box of potion materials from your father at that time. He suffered a loss. 】

There are many things that Till doesn't know, but the system often sits in the unconscious Till's mind and eavesdrops on things going on around him.

How many times Mrs. Emery sighed, how many times she wiped her tears, and how many days Professor Dumbledore skipped candy, the boring system recorded them all time and time again.

Mr. Emery originally wanted to thank Professor Snape with gold galleons, but Professor Dumbledore said that potion materials were more precious to Professor Snape. Mr. Emery immediately brought three large boxes of expensive potions. The materials went to Professor Snape.

However, Professor Snape only accepted one box. No matter how much Mr. Emery persuaded him, the other two boxes just couldn't get into Professor Snape's office, so Mr. Emery had to take them back and return them.

To put it systematically, Professor Snape is really a strange person. If he is qualified to be a human being and he has toiled hard for more than three months to brew the soul potion, he will definitely accept all the rewards without ceremony.

After hearing what the system said, Tier was silent for a moment.

She knew that Professor Snape was kind to her. Although he was willing to help brew the soul potion, a larger part of the reason was Professor Dumbledore's wish. However, he was supposed to wait until she drank the first bottle of soul potion, but he didn't. Stop immediately after waking up.

But he didn't, and instead sent soul potions one after another.

Both emotionally and logically, she should say thank you to Professor Snape.

Tyr's fingers traced the belly of the potion bottle. Although the soul potion had lost its medicinal properties, some magic power remained in it, which vibrated in the potion bottle as the liquid flowed.

Tyr stood up suddenly, tore off a piece of paper and wrote a few words, then attached a bag of gold galleons and asked Habby to send it to Diagon Alley.

To Diagon Alley instead of Professor Snape? The system expressed incomprehension: [Host, why don’t you just send a note of thanks to Professor Snape? 】

【You will know in a moment. 】Tiel replied awkwardly and sat back at the desk, but he was obviously a little absent-minded and his writing speed was much slower.

Haibi came back soon. The note and the bag of gold galleons were gone, replaced by a large jar of dried blue worms.

Teal simply packed it up in a box and asked Hibby, who drank a few sips of water, to take it and set off again, this time to Professor Snape.

[Host, would you like to give Professor Snape a jar of worms as a thank you gift? 】The system was greatly shocked, waiting for Tier's answer.

Till just smiled slightly, with a hint of meaning in his smile.

What she gave to Professor Snape was the Billywig worm. Others may not understand it, but Professor Snape will.
