Days to grind friendship at Hogwarts

Glenn accompanied Morgana all the way back to Gryffindor Tower, waited for her to get through the doorway at the entrance of the lounge, and then opened the map again.

Looking at the lonely "Automatic Pathfinding" in the function button bar on the right, he remembered the words "upgradeable" when he just obtained the system map.

A little greedy...

How about...try it?

Anyway, now we already have Flash and Disguise Magus. When in danger, we can flash and change our appearance, and our escape efficiency will be maxed out, and we will have almost no natural enemies.

As for the combat effectiveness on both offense and defense, relying solely on a milestone reward may not make a qualitative leap.

What if after upgrading the map, there is an additional function of displaying people's names, isn't that a blood profit?

What else do I need from the Marauder's Map, and what do I need from a bicycle?

Since I can't think of any better choice at the moment, I'd better write down the upgrade map first to avoid the embarrassing situation of reaching a milestone by chance, but the reward is still blank.

Glenn no longer hesitated and quickly made his choice.

The milestone interface flashed, and the custom reward turned into a map upgrade.

With another worry settled, Glenn hummed a little tune, accompanied by the system voice saying "There are thousands of roads", and walked briskly back to the common room.

...

The next day came Sunday again, which was the day for the Advanced Potions class.

Glenn, who had completely gotten rid of the troubles of being a wanderlust, had a solid sleep, had breakfast slowly, and then set off from the auditorium to the underground floor.

When he arrived at the door of Professor Snape's office, the time was just right.

He knocked lightly on the door, waited for a cold and low "come in", and then opened the door and entered.

Today's office is different from the past, it seems a bit crowded.

Two little wizards wearing Slytherin robes were sitting at the table, looking at the Half-Blood Prince's notes from his youth.

It seems that the Potions Advanced Class has expanded its membership.

A boy and a girl were freshmen in the same grade, and they looked somewhat familiar.

The character cards accurately display the information of the two people.

...

Windsor Moriarty

Grade: White Mediocre

Bloodline: Ordinary pure-blood family lineage (c)

Charms:lv.0

Transfiguration:lv.0

Black magic:lv.0

Special abilities: Potions talent, magical animal affinity (weak)

Special items: none

Skills: Slightly

The boy among the two was nothing special, he was just an ordinary descendant of a pure-blood family with a little talent in potions.

But this little girl is a bit intriguing.

Putting aside the mysterious animal affinity, the name alone is extraordinary.

There is such a name that every detective novel lover must have heard of.

Sherlock Holmes.

The great detective who lives in 221b Baker Street, London.

And this lifelong enemy of Mr. Holmes is named James Moriarty.

Glenn frowned slightly, his eyes falling on the pink-haired, cute-looking little girl.

Ever since he learned Morgana's true identity, he seemed to be suffering from PTSD (post-traumatic stress disorder). As long as he saw a familiar name, he would involuntarily start associations and suspicions.

Professor Snape, who always had a straight face, couldn't help but frown even more when he saw Glenn standing at the door, reluctant to go in.

"If you don't plan to come over yet, please close the door when you go out, Ollivander." His words were thorny and his tone was serious.

Glenn instantly calmed down, put on a flattering smile on his face, closed the door gently, and sat down on the empty seat left for him.

The two people who were studying with their heads down glanced up. Windsor Moriarty seemed to be very interested in him, and his eyes stayed for a while.

Glenn couldn't hold it back and asked quietly: "Is there an elder named James Moriarty in your family?"

"No..." Windsor Moriarty was confused, "But how did you know that my surname is Moriarty?"

Glenn showed an incomprehensible expression, as if he was a "mountain man with his own clever ideas", but he was relieved in his heart.

It seems that I have thought too much...

However, he didn't know that behind him, Professor Snape gently lifted his sleeves and was selecting suitable books.

"Bang!"

Glenn only felt that the back of his head was hit hard by something heavy, his vision went dark, and he almost hit his head on the hard solid wood desk.

"Hiss..." He stretched out his hand to cover the back of his head where he had been hit hard, but did not dare to look back at all, and opened the old notebook in front of him with his other hand.

I felt aggrieved, as if ten thousand alpacas (crossed out) were running past.

Opposite him, Windsor Moriarty covered his face and laughed wildly, almost sounding like a pig.

The boy Fierra Foley pretended to be cold and arrogant, forcing a straight face, but couldn't help but smile a little.

Professor Snape glanced at Windsor Moriarty with his sword-like eyes. The little girl looked stern and lowered her head obediently.

"Hurry up and read today's content. If something goes wrong, I will feed you and drink it myself."

Glenn shivered and quickly lowered his head to read the contents of the note.

Shrinking Potion

Glenn breathed a sigh of relief. This kind of third-grade content was purely child's play to him, and it was even much simpler than the low-end version of the intelligence enhancer practiced in the first improvement class.

He raised his head slightly and looked at the operations in the hands of the two people opposite him. It was a swelling potion that was easier to prepare than the shrinking potion. It was usually learned in the second grade.

Professor Snape seemed to feel Glenn's relief, and a glimmer of light flashed in his deep black eyes.

"Sorry, I got the wrong notebook."

Glenn's eyes flashed, and the notebook containing the shrinking potion disappeared instantly.

The professor turned around, rummaged through the messy bookshelf, found another notebook, opened a page, and placed it in front of Glenn.

It was written in the Half-Blood Prince's characteristic scrawled notes——

Laughter Potion

Glenn's eyes narrowed and he smiled bitterly.

He had read the Potions textbook, which was for sixth grade.

"Professor..." He turned around with a flattering smile, "Did you take the wrong notes again? Isn't this a bit difficult..."

Professor Snape ignored him, turned around and returned to his desk, flipping through a Potions magazine by himself, but the corners of his mouth seemed to be slightly pulled upward.

Glenn, who had a hot face but a cold butt, turned around and looked down at the contents of his notes.

Fortunately, the Laughter Potion is one of the simplest in the sixth grade curriculum, and is far less complicated than the Polyjuice Potion.

Glenn glanced at the contents of the note, and found an option for [Laughter Potion] in the system skill bar.

He couldn't help but secretly feel lucky that he had this buggy Potions skill bar.

System Dad, the eternal God!
