[Makes sense! 】

The bronze eagle suddenly spoke, and a gentle voice continued to echo in the confined space, and then the heavy bronze gate slowly opened.

Looking at the open door in front of him, Ivan was directly stunned in place, and he couldn't help but feel a sense of absurdity.

He spent more than a week looking through the forbidden book area and couldn't answer the questions, and was so easily solved by Luna?

And the answer is still ...... Simple?

Luna, who was on the side, seemed to see Ivan's doubts, and quickly explained. "Bronze Eagle's questions usually don't have a fixed answer...... As long as it thinks what you say makes sense, it will open the door for you......"

Ivan nodded with a smile, he understood that he had thought about it from the beginning, and the bronze eagle did not deliberately target himself.

It's just that he was preconceived, frightened by the difficulty of this question, and confidently believed that he had the ability to explore the nature of magic, so he directly regarded this as a Ravenclaw test for himself, a duel that spanned thousands of years!

However, the facts told him that he was just fighting the air...... The other party set this question, probably just expecting the students to give a variety of different answers?

Perhaps, even Ravenclaw himself has not been able to figure out what the nature of magic is, otherwise there would have been a record of it in the forbidden section.

"Helena is right, I'm really not a good fit for Ravenclaw......," Ivan said complainingly.

After this "test", Ivan also understood one of his flaws, that is, he lacked magical thinking, and his brain circuits were completely incompatible with the Ravenclaw lady who lived more than a thousand years ago.

Let's say the bronze eagle asks: What is the essence of water!

He would certainly have replied that water is an inorganic substance made up of two elements, hydrogen and oxygen!

But the actual reference answer - water is the source of life!

In this regard, Ivan just wants to say one thing about MMP!

"Shall we go in? Ivan? Luna looked at the open bronze door, her eyes full of inquiry, and turned her head to ask.

"Well, let's go in together!" Ivan collected his thoughts, put those chaotic thoughts behind him, and walked in first.

Inside the bronze door is a very large research room, which has been unexpectedly well preserved after a thousand years, but it is only stained with thick dust.

The old mahogany table in the center of the room houses a number of research manuscripts and magical materials, and the surrounding walls are filled with various magical books.

In addition, Ivan also noticed that the magic in this research room was extremely active, and as soon as his mind moved, a flame appeared in the palm of his hand out of thin air.

Although he had already mastered the art of casting spells without a wand, he had not been as smooth as he had been tonight when casting magic in the past.

"Extraordinary wisdom is the greatest treasure of mankind......"

A dreamy whisper sounded in the research room, interrupting Ivan's thoughts, and he looked back to see that it was Luna.

At this moment, the little witch stood in front of a blue-white stone tablet, looking at the words of the stone tablet intently.

Ivan walked a few steps and realized that the text on it was written in the ancient runi script, and the text was not very complete, and he could not fully understand it.

However, it is not difficult to confirm that combined with Luna's words, it is a famous quote from Ravenclaw - extraordinary wisdom is the greatest wealth of mankind!

However, to Ivan's strange feeling, there was a deep crack on the surface of the stele, almost splitting the entire stele in two.

Ivan was quite sure that this was not the result of natural weathering, but the traces of a magical blow.

This is a bit intriguing, if there is no latecomer to destroy it, then it is not said that Ravenclaw himself destroyed this stone tablet.

"Probably Lady Ravenclaw didn't agree with this in her old age......" Luna whispered as she reached out and gently stroked the crack in the stele.

"Why do you say that?" Ivan looked at Luna with interest and asked.

"There's no why, that's it......" Luna said, shaking her head. Otherwise, I can't think of a reason for Ms. Ravenclaw to destroy the stele......"

Ivan was speechless.

Intuitively, I wondered if it was ......

If someone else said this, Ivan would definitely think that the other party was talking nonsense, but Luna was an exception, and the other party's intuition could almost be regarded as a talent!

In addition, Ivan already had some guesses, so he nodded in agreement. "Maybe you're right, Luna, but as for the reason, I'm afraid it's because of Helena......"

"You mean it has something to do with Ms. Gray?" Luna asked curiously.

Ivan didn't mean to hide it, and even told the story of Ravenclaw's daughter Helena, who stole the crown in order to become smarter and more famous than her mother, causing the mother and daughter to almost break up, and finally causing tragedy.

Legend has it that after her daughter went missing, Rowena Ravenclaw devoted all her energy to the study of magic.

Ivan suspected that Rowena Ravenclaw probably looked at the stele every day, and then remembered that he had betrayed his daughter in order to gain superior wisdom, and in a moment of anger, he slammed into it with a spell.

"Lady Ravenclaw seems to have found something as important as wisdom......," Luna muttered to herself, looking at the broken stele. Affection! ”

Speaking of which, Luna's mood became a little low.

Ivan understood that the little witch must have thought of her mother, who had died in a magical experiment, and hurriedly changed the subject, beckoning Luna to search the research room together.

Due to the passage of thousands of years, many of the alchemical manuscripts in the laboratory have become blurry and illegible, which has added a lot of difficulty to their search work.

Fortunately, some of the most critical research manuscripts were kept by Ravenclaw in jade boxes, on which he had learned some of the ancient English and ancient runes, and Luna, who quickly translated the relevant research manuscripts.

"That's it!" Ivan followed the description in the manuscript and found a large clearing at the back of the research room, half-crouched on the ground and tried to enter some mana.

Ahead, the blue-white floor stone tiles suddenly lit up, gradually outlining a complex and exquisite alchemy circle.

With Ivan's knowledge of alchemy, it can be seen that the function of this magic circle is to mobilize the magic power of the entire castle, which was probably used by Ravenclaw to do some high-intensity magic experiments back then.

However, this saved him a lot of preliminary work, as long as he took some time to improve it, and then matched the materials to make the Philosopher's Stone, he could get a Philosopher's Stone of his own!
