During this time, while listening to it, Rosen wrote out "In-depth Investigation into the Nature of the Polarity of Mana". He wrote it with two quills together, in duplicate.

After finishing writing, he handed the manuscript paper to the two women respectively and made a small fuss.

"This new knowledge I bought from the Mage Guild along the way, I think it may be helpful to solve this problem."

The two women immediately immersed themselves in watching.

Once I saw it, I was deeply immersed in it.

Rosen hadn't finished reading it yet, so he closed his eyes and continued reading in the virtual machine.

From morning until night, it was nine o'clock in the evening.

Rosen already had the initial idea of ​​a spell lock.

"Anna, Jenny, this article gives great insight into the polarity of mana."

"It can be seen that the essence of mana polarity is a spell, and it is a special spell that is almost pure and cannot be perceived by the subjective consciousness of the caster."

"Then, we can completely use the characteristics of 'ignorance' to construct a spell lock that can be recharged and can avoid other mages from probing the structure of the magic weapon."

Gendeloni hadn't figured it out yet, she frowned and thought hard.

Thrandis already had an idea, and she laughed.

"My dear, what you mean is to use the inner magic rules to reconstruct the petrification technique."

"And because the mage cannot perceive the fine structure of the inner magic, when charging and using it, naturally there is no way to know the structure of the magic weapon, let alone the principle."

‘Pah~’

Rosen snapped his fingers.

"Anna, it seems we have thought of getting together."

Gendeloni also understood and immediately asked a new question.

"But what if the other party takes apart the magic weapon and looks at it directly?"

Rosen laughed: "This is simple. We can use the same internal magic principle inside the magic weapon to bind a triggered and bundled charging disintegration spell."

"Once the magic weapon is destroyed, it will trigger disintegration and directly destroy the fine structure of the magic weapon."

Gendeloni nodded: "It seems like the problem has been solved."

Rosen shook his head: "I just have an idea, but the actual implementation is very difficult."

After speaking, he clapped his hands again.

"Okay, it's late, go to bed. When you get up tomorrow, we will work together to get the encrypted petrified magic weapon out!"

After a pause, he added something

"To provide maximum assistance, it would be best if it could be the same as the rune stone, which even a fool can use. Of course, I know this is impossible. Anyway, just try to lean in this direction as much as possible."

After saying that, he stood up and walked to the guest bedroom.

"Wait~"

Thrandis shouted: "I want to sleep with you today, and Jenny will sleep alone."

Rosen waved his hand casually and yawned: "No, no, no, you sisters, go to sleep."

Gianni Loni's voice also sounded, weakly: "Rosen, don't let me make you and your wife always have separate rooms. I will sleep in the guest bedroom today."

Alice's magic light and shadow emerged: "I said, can you please stop going to so much trouble? The bed is so big, it can sleep three people without being crowded!"

Ana paused, then nodded: "I have no objection."

Gendeloni pursed her lips and her cheeks turned red, but in the end she nodded: "I don't care."

Anyway, it's not the first time.

Rosen turned around and entered the master bedroom.

"Then I'll go to bed first. I'm really tired today, so I won't bother myself tonight."
