In another world, Lu Mingfei is learning card making.

—So, some people might ask, "Lu Mingfei, Lu Mingfei, don't you have to go to your extracurricular class today?"

Haha, you really don't need to.

Because he had already learned almost everything that could be learned about musical instruments in this small city—

After all, this was just a small city. As the red-robed acolyte said, "there wasn't even a decent high society." Therefore, there were only so many places for him to learn and improve, and many of them weren't even that great.

In terms of musical instruments alone, most of the skills he could learn from his teachers only supported him to level 1, with only the violin and piano reaching level 2; some more niche instruments, such as the organ, were not even fully understood by the teachers themselves, and were even still at level 0.

It was precisely for this reason that, before he had decided what to study next, Lu Mingfei had a rare period of free time—

You could even create a group chat with Lao Tang online and play a couple of tutorial games for them as material.

The red-robed acolyte, of course, wouldn't concern herself with such a trivial matter. Online communication is still communication, and she wouldn't be like those stubborn parents who insist on ordering, "You can't play on the computer."

"But, well, but..." Lu Mingfei continued to open the QQ group chat, looking at the interactions among the group members, "Although I have some free time now, I still can't slack off on important matters..."

"Ugh, Halloween..."

Halloween, November 1st, is also known as All Saints' Day.

There are still about two weeks (referring to St. Marian) until now.

Of course, on Earth, since it's not a traditional holiday, there's actually no reason to celebrate. The reason Lu Mingfei brought this up now is actually because:

They celebrate Halloween in another world too!

It's on the same day as Earth!

During Halloween, the school will give children a holiday so they can go home and spend time with their families; for those like Lu Mingfei who choose to stay, the school has prepared a special holiday activity—

Halloween ghost hunting game!

Catching ghosts will earn you reward points, which can only be used on Halloween. According to the redemption chart provided by upperclassmen, their purchasing power is roughly equivalent to academic credits.

Because each elemental crystal costs 50 credits, it also costs 50 credits on the exchange chart.

However, in a sense, reward points are actually more important than academic credits, because there are some things on the reward points redemption list that cannot be bought with regular academic credits.

So Ron and Lacey chose to stay even though they could have gone home, intending to take this opportunity to earn a lot of credits.

However, if you want to earn credits, the first thing to consider is: you need to have a Pokémon card that can defeat monsters.

This question alone stumped many of the new students: many of them couldn't even guarantee success in refining cards, let alone meet the prerequisites of "high star rating" and "special attack against ghosts and monsters".

"Alright, I don't need to worry about that. After all, Miyamoto Musashi's Niten Ichi-ryu is enough to kill demons, and he himself is a Level 2 card, so his strength is definitely there..."

Lu Mingfei pondered, then left the computer and lay down on the bed, preparing to experience the disorientation of traveling through the world—

"The only problem is, I don't have any protective gear. How am I supposed to avoid being attacked by those monsters?"

……

Wednesday morning, Magic Class.

Professor Aswei walked in carrying a huge box and casually said to Lace in the front row:

"Come on, help me distribute these things—this is the card-making material we'll be using today."

"We've covered the basics of card crafting, including all the fundamental transmutation arrays, qualitative analysis of materials, and some helpful tips for getting started. Starting today, we'll move on to the next section:"

"An Overview of Advanced Card Making Theory"

Lacey placed stacks of materials in boxes on the first row of tables, letting them pass them around to the back, while Professor Aswei ignored the commotion from the audience and continued today's lesson from the podium:

"Advanced card making is actually a very broad concept. Theoretically speaking, as long as it is not made using the basic forging array, it is considered advanced card making—don't be fooled by the name 'advanced,' it is actually very simple."

"For this subject, there's only one requirement for you first-year students: construct a usable array diagram. Today, we'll focus on the Zero Transmutation Array..."

How to construct a usable array?

It sounded like a topic Lu Mingfei had already completed, but he still listened attentively—the reason was simple: there are differences between constructing different array diagrams.

Just like programmers, using various tools to write code makes you a programmer, and directly Ctrl+C+V also makes you a programmer, but if we really want to talk about it, the former is definitely more impressive.

St. Marian's teachers, aside from anything else, had solid fundamental skills—they rarely stopped at studying a single set or type of array diagram, but rather developed new logic for refining array diagrams—

Therefore, even though Lu Mingfei could even create a transmutation array for Luo Tianyi, he still felt he benefited greatly from the lesson.

"Alright, that's about enough time for today's lecture. You can open the boxes and start today's practical exercises." Aswei clapped her hands, drawing everyone's attention.

"Do you know why I chose to talk about Transmutation Array Zero?"

"Because array diagrams formed by Zero-level transmutation arrays are often the most likely to create magical spirits that can subdue ghosts and monsters!"

Upon hearing this, the entire classroom erupted in cheers—

Clearly, the teachers were thinking of the students' best interests. In order to help them achieve good results in the game, they deliberately changed the order of their lessons.

Seeing that the atmosphere in the classroom had become lively, Asvi smiled and said, "Everyone, please feel free to do as you please."

Everyone immediately started opening the boxes, and those impatient people who opened the boxes as soon as they were handed out even started engraving alchemy circles on the cards.

Lu Mingfei remained calm and unhurried. He first opened the box, which contained a typical pile of materials—but besides the ordinary materials, there was also a very special item wrapped in a bag:

[Item: Siren Scale]

[Type: Creature Material/Illusion/Ocean]

[Quality: Excellent (Green)]

[Description: Scales that naturally shed from a siren are collected and processed using magic to unleash their latent magical power. Listening to them, one can almost hear the siren's song.]

[PS: Sirens would sing songs to lure people off ships and overboard into the sea. Because this was so effective, many people were unaware of this ability. Until one day, a dwarf aspiring to travel the world boarded a ship—from *The Bard's Jokes*, p. 13]

[PS: The stories about dwarves in *The Bard's Jokes* are placed at the beginning because the book is too thick for dwarves to open.]
