That night, Filch and Link returned to Hogwarts.

Although Filch said that he was not afraid of Link spreading the news that he was a squib, he was still afraid in his heart.

So along the way, Filch had a stern 'I have something to say to you, but I just won't speak first'.

Link ignored him either, and instead went straight back to his dorm room to begin his summation of what Lupin had taught.

This was necessary, as it would speed up his research on the advanced abilities of the Renewal Spell.

In this way, after consuming nearly two weeks of spare time, Link finally mastered all the abilities of the Renewal Spell lv4, and summed up three new spells, namely the urinary urgency spell that uses the opponent's bladder as a container, the suffocation curse that uses the opponent's alveoli as a container, and the human explosion curse that directly uses the opponent's entire body as a container.

Among them, the suffocation spell and the human explosion curse are really lethal spells, and the suffocation spell is slightly better, although the person hit by it will directly enter a state of severe suffocation because the air in the alveoli disappears instantly, but the person who is hit by the spell can still survive for a while.

The Human Explosion Charm is different.

Link once experimented with mice, and the scene after the little guy was cursed was so miserable that Link didn't want to remember anymore, which is why Link named this spell the Human Explosion Curse, because those little guys really exploded directly at that time!

As for the effect of the Urgency Charm, which can make people urinate urgently and even pee their pants, this is just a mischievous spell that Link has researched for fun, and it is a prank spell similar to the 'Incisor Stick'.

After developing these three spells, Link's research on the Renewal Spell has come to an end for the time being.

This is not because Link doesn't want to waste time on the renewal spell, but because the renewal spell lv5 has rigid requirements for both magic and mental power, and with Link's current situation, he is not qualified to try it for at least a long time in the future.

But Link didn't rest on his laurels, as there were no surprises around him like the one he had at the beginning, so he could have focused on studying other spells.

To be honest, Link really likes this kind of dull life.

Compared with the thrilling and unexpected life of the protagonist, he prefers to be like many of the bigwigs who have appeared in Hufflepuff House, slowly develop and make a fortune.

It's a pity that God doesn't want Link to live so comfortably.

This time of relaxation lasted only until the first Thursday evening in October, when a paper airplane interrupted it.

It was really a pretty good paper airplane, and judging by its great ability to stay in the air and its good flight speed, Link could have sworn that it was definitely the treasure that all the little boys in his previous life could only dream of!

And it turns out that no matter how the world line changes, boys are still boys.

As soon as the paper airplane flew into the Hufflepuff Lounge, it attracted the attention of all the boys present.

Even Cedric, who was still chatting with Link just now, was no exception!

Even the boys who had some good things came up and were ready to catch it and study it well.

It's a pity that this paper airplane came with a mission.

I saw that it deftly avoided the obstacles of one boy after another, and finally came to Link to quickly stretch and deform, and finally made an origami mouth.

"Link, come to my office! now! right now!"

Snape's familiar voice came from inside the constantly open origami mouth, which made many of the boys who wanted to continue to grab the paper airplanes instantly change their faces and obediently retreat to their seats.

The origami mouth fell from the air as soon as Snape's words were delivered.

Seeing this, Link sighed softly in his heart.

Snape called him over at this point, and it must have been because of the pills.

He was still wondering if he had been taking his medicine on Monday, but Link hadn't been notified by Snape when he returned.

It made him think that Snape had given up on drugged him.

It's a pity that in the current situation, the other party may have delayed the time just because of something.

Shaking his head, Link picked up the origami mouth on the ground and was about to leave.

The surrounding Hufflepuffs didn't react much, and it was no secret to Hufflepuff that Link would be called to the office by Snape every week, and they were no longer surprised.

It's just that Cedric obviously didn't think so, and as soon as Link got up, he reached out and grabbed Link's arm, and at the same time made a worried expression.

Although he didn't speak, Cedric's meaning was still conveyed to Link accurately.

Link smiled, waved his hand and said:

"Don't worry, Cedric. Snape wasn't a nice guy, but it didn't matter if he called me over. ”

Hearing this, the worry on Cedric's face became stronger, but after hesitating for a while, he still let go of his hand and said:

"If you have something, you can talk to me and Professor Sprout, don't keep it in your heart. ”

"Got it, you can rest easy. ”

With that, Link waved his hand and went to Snape's office without looking back.

Snape's office hadn't changed much since the last time he had visited, just like Snape himself, who had been dressed in a black robe and had greasy black hair for ten thousand years.

Of course, Link didn't have any problem with this, and after a brief look at his office, he greeted Snape, who was sitting at his workbench boiling potions:

"Professor Snape, it's been a long time, I thought you were going to forget about it!"

Link's voice was extremely enthusiastic, but Snape wasn't buying it.

He just glanced at Link, then raised the tongs and carefully packed the potions in the cauldron into two separate glasses.

Then, just like last time, Snape raised the potion directly in front of Link.

"Drank it. ”

Listening to Snape's indifferent topic without a hint of emotion, Link didn't move, he just stared at Snape quietly, as if waiting for something.

"Tsk!"

Three minutes later, Snape let out a grunt of displeasure, then raised his glass and drank it down.

Seeing this, a smile appeared on Link's face, and he didn't wait for Snape's command, he took the initiative to pick up another cup of potion and took a very bold sip.

No, no, the smell of this potion is so exciting, rather than going through a little bit of torture, it's better to do it simply.

Seeing this, Snape's originally gloomy expression also looked a lot better.
