The villainous young master just wants to live a Buddhist-like life.

　……

　Dak has a very strong interest in armed cards.

　It's not just because they want to recreate the Saint Cloth.

　When he has nothing to do, he sometimes thinks about it.

　Is Gundam considered an armed force?

　Does Ultraman count as an armed force?

　Where is Iron Man?

　Emmm...

　This is a problem.

　……

　Being a mage is actually a highly creative profession.

　As your skill level increases, the number of things you can do will be unimaginable.

　……

　Time passes bit by bit.

　After two more imaging attempts, Dak finally managed to sketch out the general shape.

　As for the precise measurements and mapping to follow, he plans to do so tomorrow morning when his mind is clear enough.

　……

　Meanwhile, Victor and the others, having gained nothing, also prepared to go to sleep.

　Both sides brought inflatable sleeping bags, which, when fully inflated, could expand to two meters in length.

　When spending a winter night away from home, these preparations are necessary.

　……

　the next morning.

　The research continues.

　However, while Dark's side has reached the final stage, Witt's side has yet to find a solution.

　This difference in outcomes is undoubtedly due to the different levels of basic education.

　Betty focused more on the magical aspects and therefore overlooked the fact that it was actually a simple optical design.

　The three of them, including Witt, didn't even bother to solve the mystery.

　Around noon.

　Dark had recorded the array diagram in its entirety. He even began to study whether he could obtain anything by shining the beam of light on the mirror at different angles, or by using a different mirror as the starting point.

　And he actually figured it out!

　As Sylveon's moonlight beam shone on one of the mirrors, a new array of light appeared inside the mirror chamber!

　This result greatly encouraged Darko.

　He realized that the numerous mirrors in the cave were not just for decoration; almost every mirror had a purpose.

　at dusk.

　Dark found a third array diagram!

　After recording the third array diagram, Dak observed it carefully. Suddenly, an idea struck him. He superimposed the three array diagrams in his mind and discovered that they seemed to form a complete sphere!

　“三位一体？”

　Dak gradually began to have some ideas.

　The entire mirror chamber contained three array diagrams, and nothing new was found after that.

　The "instruction manual" or similar document that I had been expecting was nowhere to be found.

　However, this is not a big problem.

　Now that we have the array diagram in hand, we only need to investigate what creative achievements Alvitt made during her student days to roughly deduce the purpose of this array diagram.

　Valkyrie wouldn't just take something that's already in the textbook and use it as a treasure, would she?

　……

　The night is deep.

　After eating and drinking his fill, Dak prepared to have a good night's sleep and return to his dormitory after dawn.

　Overjoyed by the harvest, he slept soundly.

　The little devilmon wrapped itself in the scarf and fell asleep with its cheek pressed against its own.

　Over the past two days, they have confirmed that the dragon's lair is very safe.

　In fact, with the dragon defeated, the entire ancient forest fell silent, and many mechanisms ceased functioning as if they had completed their tasks.

　It didn't collapse on the spot only because there were still people inside.

　……

　While Dak went to sleep early, Witt and the others, having gained nothing, started a campfire out of boredom.

　Although the campfire was a toy campfire sold in Traveler's Street, essentially a kind of magic stove, it still managed to create some atmosphere.

　However, in the firelight, none of the three looked well.

　Witt was disappointed, Robert was frustrated, and Scott was somewhat ashamed of his vows before entering the secret passage.

　By the end of the day, they had lost the composure they had the night before, with only Betty still racking her brains in the secret room.

　But as time went on, Betty eventually had to leave the enclosed room filled with mirrors.

　She rubbed her temples, feeling her vision blurry.

　Scott, do you have any hot coffee?

　Betty shuffled toward the campfire, wanting to replenish her sugar (she frantically added sugar cubes to her coffee).

　"Just a moment."

　Scott took a small can of coffee out of his bag and threw it into the still-unboiled water.

　Betty sat down beside him, hugging her knees and looking ahead, her gaze gradually drawn to the campfire.

　Vittor couldn't help but ask, "Senior, what did you learn?"

　Betty kept staring at the campfire, ignoring him.

　Witt: "Senior?"

　Betty suddenly stood up: "I've got it!"

　Witt: "What's done?"

　Betty: "We need a highly cohesive light source!"

　……

　As Betty had a flash of inspiration, Victor's treasure hunt finally came to an end.

　Betty used a live alchemy method to create a simple light source that could emit a bright beam of light, and then immediately entered the secret room to shine the beam of light on the mirror.

　Half a minute later, she came out with a happy expression.

　Witt, who was anxiously waiting at the entrance of the secret room, rushed up and asked, "How did it go? Did it succeed?"

　Betty raised an eyebrow and said smugly, "Of course, don't you know who I am?"

　"Let me see," Witt exclaimed excitedly.

　Betty then handed him the light-emitting device: "Just infuse it with magic."

　Witt rushed into the secret room immediately, unable to contain himself.

　After he infused the light-emitting device with magic, and then, following Betty's instructions, shone the beam of light from the entrance of the secret chamber onto the mirror directly opposite, a light array immediately appeared before him.

　"Is it really such a simple design?"

　Witt's face flushed red, and his hands trembled with excitement.

　"Is this the treasure left by my father?"

　What kind of formation could it be?

　"Ancient magic circle?"

　"A custom alchemy array?"

　"Or is it a special spell presented in the form of pictures and text?"

　He couldn't help but start daydreaming.

　……

　Outside the secret room.

　Scott asked curiously, "Did you find anything?"

　Betty glanced at him, feeling somewhat pleased: "It must be a curse."

　Scott exclaimed excitedly, "A curse left behind by a hero? I'm going to check it out!"

　Betty shook her head and said, "That's not a good idea. Since it's something left behind by the hero, it should be received by the hero's son. Besides, it's not a spell that just anyone can use."

　Scott accepted her explanation: "The things left behind by heroes are always special. It's a kind of fate that Witt was able to obtain his relics!"

　Betty rubbed her temples: "I need to rest for a bit. The rest of the recording work is none of my business."

　Scott shrugged: "That was, of course, Witt's own work."

　Betty then went to the campfire, put on insulated gloves, scooped out the hot coffee, opened it, poured it into a teacup, and added a sugar cube.

　In the shadows where no one could see her, she pursed her lips slightly.

　Although it was a pity, she had actually recognized it when she saw the curse.

　It's a universal spell, and indeed, not everyone can use it.

　Because it comes with a verification function, it will change into a form that matches the owner's various qualifications.

　Only by transforming into a weapon can the basic function of the spell be brought into play.

　The strength of the spell varies depending on the weapon it is transformed into.

　Among them, the "sword" is the most powerful!

　Its name is "Phantom Soldier Spell", and it belongs to both the spell card and the item card category.

　Because it is often used by heroes to summon the holy sword, it is also called the "Holy Sword Spell"!

　……

　The reason Betty knew so much was because the "Holy Sword Spell" was something that could be learned in the second semester of fourth grade—she had previewed it!

　Within half a minute of recognizing the curse.

　She decided to keep this secret in her heart forever.

　It is not her intention to shatter a child's beautiful illusions about her parents' generation.

　Of course, she didn't want to hide it.

　But who knew that the treasure left behind by the hero would be something that was already in the textbook?

　Anyway, by the time Victor reaches fourth grade, she will have already graduated...

　"This is absolutely terrible!"

　……

　Three of the four were immersed in joy, and even Robert was secretly happy for Witt.

　Witt finally thought of Robert. He asked Robert to enter the secret room and help carry the light-emitting device, while he himself began to record.

　Although the "Holy Sword Spell" is not short, it is at least a two-dimensional spell, so it is not difficult to draw.
