Congenio's reminder made Xia Duo feel that he really didn't come in vain this time, if he didn't know the tripartite contract, when he really found a Mithril mine in the territory one day, it would really be a hardship.

Of course, even if we know the existence of the three-party contract now, even if we know some loopholes to circumvent the contract, as long as the contract is not dissolved for a day, it is still very unpleasant.

Think about it, a color-resistant mage discovered a sub-plane full of mythril ore, and at the same time known to the elves or dwarves, if this plane is considered a color-resistant territory, then the elves or dwarves want a mine.

And if this plane is not considered the color-resistant territory, then people even have to occupy a share of the plane!

Xia Duo guessed that the Seven Towers had been exploring the sub-plane for quite some time, but they rarely revealed it to the outside world, and perhaps there was a reason for this!

Thinking of this, he couldn't help but ask, "Master, is there any way to terminate this contract without affecting other interests?" ”

"Difficult! Hard! It's very hard! ”

Congenio shook his head again and again, and said three difficulties in one breath, "Unless Nesseriel can be strong enough to have an overwhelming advantage over Yerlan, Danzo, and even Comanso, this is possible, but if there is really such a day, the contract should have expired long ago." ”

After saying that, Congenio glanced at Xia Duo expectantly, and said, "I don't know if I can see the day coming, and the future depends on you batches of young people!" ”

"I won't let the master down!" Xia Duo said solemnly.

"I hope so!"

Looking at the high-spirited young man in front of him, Congenio finally felt a little more joy in his heart, he had talked to many young people about this topic in the past, but unfortunately, those people did not develop into what he hoped to be.

Congenio didn't know if Chadora could become the leader who led Nessera to break out of the encirclement, but at least at this moment, he was quite happy to hear the other party's clear statement.

"That's all for the time being, I know you won't just ask about Innosen, and if you have any questions, as long as I can answer them, I will answer them for you."

The master's tone was very sincere, which made Xia Duo's heart a little touched, he came to visit the master with some utilitarian thoughts, but after this contact, he also found that the master did live up to the rumors, quite the style of the ancient sages in his hometown.

If such an image is also a kind of disguise, Xia Duo is really hard to imagine, can disguise for hundreds of years without revealing the stuff, then there is not much difference from the real thing!

Thinking like this, Xia Duo had no doubts in his heart, took out the twelve books that had been prepared from the dimensional bag, and put them on the tea table between the two.

"Shado, you're—"

"Master, this is my gift to you on behalf of the Tower of Time."

In fact, when he decided to visit Congenio, Xia Duo conceived of many kinds of gifts, of course, in the end he chose only two, one was his imitation of the Ain Stone, and the other was these books.

If you simply send money (including resources), for a Grand Arcanist who has lived for hundreds of years, how much money does it take to impress the other party?

Besides, it's too vulgar to give money.

The gift of the Ayn Stone was heard by Xia Duo from Brendes, and although the master himself never announced it to the public, he did like to be given the Ayn Stone by others, especially those new versions that were innovative, and they were often praised by the master.

Xia Duo also prepared an Ain Stone, but due to the tight schedule and the fact that the Tower of Time did not have many high-quality gems for him to try, he was not able to innovate and simply imitated a spell reversal Ain Stone.

But this gift was only regarded by him as a guarantee, and the book was what Xia Duo really wanted to give, although the cost was far less than the Aine Stone, but the meaning was far from being comparable to a mere Aine Stone.

After determining that Congenio did live up to his reputation and was very likely to be in the same camp as him, Xia Duo decisively chose to give the book.

These twelve books are actually a series of books - "The New Tower of Time Level 2 Apprentice Textbook".

These include:

"Spell Casting Training" Volume 1,

"Focus on Training" 1 volume,

"Application and Analysis of Common Spells" 2 volumes,

Inner Plane, 2 volumes,

Arcane Geometry, 3 volumes,

"The Use and Crafting of Magical Items" 2 volumes,

and 1 volume of "Appreciation of Elven Magic". (including Elvish language and simple elven magic recognition and response)

There are twelve books in total.

The Level 1 apprentice textbook is actually magic enlightenment, which is more about broadening your horizons, and not even about getting in touch with real magical knowledge.

After learning the level 2 apprentice textbook, you are considered a level 3 apprentice, and level 3 apprentices can almost be regarded as official mage seeds.

Next, according to the rules set by Xia Duo, as long as you complete the [Ascension Trial], you can be promoted to an official mage (if you don't upgrade through the Ascension Trial, you will not be able to open the official mage permission, similar to the exam promotion~).

Such a set of books can be said to be of great significance, and in addition to the content of the book, the material of the book also has a very far-reaching significance.

This is a set of books made entirely from artificial wood pulp paper!

In fact, when he first saw the books, Congenio noticed the material of the paper, and at first he didn't think anything was wrong.

After all, elf paper bears the name of an elf, and it is also popular in Nesserel, in addition to being expensive, the writing experience and lightness are better than parchment.

But when he saw the names on the covers of these books, Congenio immediately had a conjecture in his mind, because the content of this conjecture was so bold that he couldn't help but breathe a little faster.

He couldn't wait to flip through the pages when a faint blue glow appeared in his hand, and then it quickly expanded, knowing that he had covered the entire set of books.

Congenio's actions were somewhat unexpected, and he recognized the spell that the master was using, and the princess had used it in front of him.

This magical spell that straddles the mind and the mind allows the caster to quickly access the full contents of a book.

After a while, Congenio opened his eyes and looked at the pile of books in front of him, he looked a little excited, but for a while he didn't know where to start, and finally burst out with a sentence:

"This is elven paper?"

"Yes, this can be said to be elf paper, but it can also be said to be Daxia paper, I have optimized the papermaking process and process, and now the cost of this paper is less than one-tenth of that of parchment!"

Xia Duo did not hesitate to put the credit for the papermaking technique on his head, of course, it was indeed him, if it wasn't for the mature papermaking technique he brought back from the projection plane, there would be no Great Xia Paper now.

As for the future, if you want to research cheap wood pulp paper, you don't know how much manpower and material resources will be consumed!

"And these books—do you have them for each of the Tower of Time apprentices?" Congenio asked again.

"Yes, every one of them has it!"

Xia Duo didn't hide this, the teaching materials were taken out, there was no need to hide it anymore, and he was ready to enlist Congenio's support!
