When Li returned from the academy to the ducal townhouse, her father had already come home.

Li thought there was a ninety-nine percent chance he had been curious about the Founding King's treasure.

That was indeed the case.

Since the conversation about her grandmother had created an awkward atmosphere, Li had simply brought the items home.

Today she wanted to take her time analyzing the magical tools.

So after finishing dinner and taking a bath, she decided to open the Jewel Dimensional Vault in the salon.

The participants this time were Li and her parents.

In particular her mother had worked professionally in developing magical tools.

So when she heard these were magical tools created by the Founding King, her interest was intense.

"Li, before we look at the magical tools, let me talk about something first."

With those words, her father began speaking.

The topic was the spoils obtained during the first dungeon training.

The Robe of the Underworld had been bought by the headmaster but Li had completely tossed the matter to her father.

Li herself would not have used it anyway.

Because of that she had thought it would be fine even if it were given away for free but it ended up being sold for quite a large amount.

In addition, Li had also received a significant share of the treasure found in the Unexplored Area.

As a result, she ended up receiving a considerable amount as pocket money.

However there was not much she could use it for.

After all Li was a noble daughter of a ducal house.

Even when she bought something, everything was charged to the ducal house account.

She almost never paid money directly on the spot.

So being given pocket money actually left her unsure what to do with it.

Therefore it was incorporated into the assets Li managed within the ducal house.

Of course that had been Li's own suggestion.

Her father also reported other details such as the profits of the trading company run by the ducal house but they wrapped it up early.

The necessary parts had already been prepared as documents.

This was exactly the kind of moment where Trismegistus was useful.

And so Li released the magical tools again.

"Hmm."

The magical tool her mother held in her hand was a cube roughly ten centimeters on each side.

When mana was passed through it, it made flapping sounds and opened like a development diagram.

There was nothing inside.

The same magical tool her mother was examining had been placed in the wooden box in a total of twenty-seven pieces.

Li thought it seemed extremely trivial.

However would the Founding King really leave behind so many meaningless magical tools?

To begin with, the Founding King had said it was a reward.

Certainly those books were valuable.

And yet this magical tool had been sealed with such a strict sealing formula.

Suspicious.

Extremely suspicious.

"Mother, Father, have you noticed anything?"

"Hmm... I feel like there must be something."

"I feel the same. Something is bothering me."

The three of them divided the work and activated the magical tools one by one.

Even though they opened in slightly different ways, it did not appear that anything had been hidden inside.

Her father let out a large sigh.

Li continued staring at the magical tools.

She wondered if the number twenty-seven had some kind of meaning.

The thought suddenly came to her.

If divided among three people it came out neatly to nine each.

Nine.

As she continued thinking in circles, she noticed that her mother had stacked one of the magical tools as if it were a block.

Seeing that, a light bulb seemed to flash above Li's head.

It was just like a Rubik's Cube.

Three cubes by three cubes made nine.

If there were three of those sets, it would become one large cube.

"Excuse me for a moment."

Li combined the magical tools in front of her to create a cube where each side consisted of three magical tools.

Then she poured mana into it.

The magical tools suddenly flashed with light.

After the light converged, a large cube appeared.

When she poured mana into it again, it once more opened like a development diagram with flapping sounds.

However this time there was a single book inside.
