"To my descendants: if you can open this spell book, then in the name of Morion Tower and Kieran Tower, I invite you to join a great project to take this spell book to Morion Tower! If you're not too far from my time! I'll be waiting for you there! ”

This text is not long, although it does not reveal what his identity is or what his great plan is, but all kinds of worded descriptions also make Xia Duo understand that this Felder is likely to be a student of the great arcanist Oshous in history.

Perhaps it was because of this so-called "great plan" that these two people, or even more, disappeared inexplicably, so that Felder was obviously a high-level mage, but he did not leave any record.

Thinking of this, Xia Duo couldn't help but glance at Nia, she was still thinking, but Xia Duo thought of Niya's great-grandfather, the Saville Grand Arcanist, who seemed to have disappeared inexplicably.

According to Niya, the Saville Grand Arcanist was exiled to a foreign land due to an accident and could not return to the main plane, and now, it seems that it is about to emerge again, and what is the inside story of this, Xia Duo has no way to guess.

But he can also speculate that Felder and Oshous are probably still alive now, maybe they are now in a corner somewhere, silently staring at what has happened to Nessrael all these years!

"Sure enough! I already knew what fifteen great arcanists! It's not reliable at all! Xia Duo thought viciously.

There is no doubt that even without these archarcanists hidden in the mysteries of history and whose fate is unknown, the Seven Towers should have the ability to make some of the existing senior arcanists quickly become archarcanists, so that the statistics are completely meaningless.

It depends on the overall Arcanist base, the most important of which is the number of senior Arcanists, but because this is also likely to be hidden, this is still a black hole data, which is impossible to see.

In addition, from Felder's message, it can be seen that this so-called "great plan" should be jointly implemented by Morrion Tower and Kieran Tower, Morrion Tower has an Oshous Grand Arcanist, so will Kieran Tower also have a Grand Arcanist involved?

Similarly, if Morion and Kiran have such a "great plan", will the rest of the Mage Towers of the Seven Towers also have their "great plan"?

Extending to Nessrael's other mage towers with Grand Arcanists, will they have similar plans?

For a while, Xia Duo thought a lot, and even speculated about this so-called "great plan", "the offspring who can open the spell book" means that this offspring either has a special bloodline, or is an arcane master like Xia Duo and Nia.

No matter how you look at it, it looks like a recruitment method, and the difference between the former and the latter is probably the difference between a guinea pig and a researcher!

So, is this so-called "great plan" related to blood?

Xia Duo speculated irresponsibly, but she didn't notice that Nia's expression on the side gradually became serious, she suddenly operated in the laboratory, and then seemed to breathe a sigh of relief, and said to Xia Duo:

"Fortunately, there is no trace of tracking, and there is no information transmitted, we had better talk less about this matter in the future, and even if we want to talk about it, it is best to choose to talk about it in the Tower of Time!"

"What's wrong?"

Xia Duo was a little puzzled, this time Nia didn't say that I would ask the teacher, but asked him to keep it a secret with a serious face, which was unusual and made Xia Duo feel that Nia should know something.

Nia didn't hide it, she said some of her guesses:

"I thought that there seemed to be an arcanist who disappeared inexplicably in the Gilles Tower, it should be after this year's snowmelt competition, that arcanist would have recently appeared in an exchange within one of the Seven Towers, but he was inexplicably absent without any news coming out, and then it seems that someone is deliberately erasing the traces of his existence, now that I think about it, maybe he participated in some unknown secret plan."

In all fairness, Nia was reluctant to join any unknown plans, she couldn't leave this large territory alone, and if she knew about the plans, she would have to join, which was really not in line with her wishes.

Listening to Nia's speculation, Xia Duo also thought of this, these plans are to deliberately erase the traces of the participants, it is obvious that there is a secret need, if he knows, he will also run outside to ask questions with a big grin, maybe he will be the one who will be erased the traces in the next moment.

Whether he actually joined a secret plan or was completely wiped out, it was not what Xia Duo wanted.

At this moment, Xia Duo suddenly thought of the fact that he had searched for Feld's materials in the library of the Austrian Law Federation, and silently said in his heart: "It shouldn't be so unlucky!" ”

Fortunately, it has been a long time since the incident, and if there were any consequences, it should have happened long ago.

But this incident also gave Xia Duo a wake-up call, if you don't want to know something, you just run outside and ask, in case you touch any taboos, maybe you don't know how to die.

This magical world is really full of pits!

Of course, this statement is a bit of a survivor's bias, and if a researcher asks about the secrets of other research institutions everywhere on Earth, he will also be treated as a spy!

……

In Nia's laboratory, the two of them were silent for a moment, and they both made the decision to keep it a secret, and this Felder spell book, Xia Duo was also going to be placed in the Tower of Time.

After all, the Tower of Time was proven to keep the Grand Arcanist out of prying eyes, but his personal space was not, and he was reluctant to take any chances, even though he knew that it was mysterious enough to keep others out of view.

At the moment, the only thing he was slightly sensitive about was this Felder spell book.

Even the materials he copied back from the [Projection Plane: Arcane Empire] were not considered sensitive items, after all, what he obtained from the projection plane, others did not know, as long as he was careful to avoid some trigger-type detection when actually using it, there was nothing to worry about.

He had already learned from the papermaking experience.

Until Felder's spell has been thoroughly studied, Xia Duo is not going to take it out of the Tower of Time, and the best place for him to study it is in the Tower of Time anyway.

At present, Xia Duo and Nia have only cracked the outer structure of the spell book, and although they have obtained the permission of the spell book, the spell book itself involves a deeper level of magic web than Xia Duo.

It's unrealistic to study it thoroughly for a while, after all, it's likely to be a spell book made by the Grand Arcanist.

Although it is a version more than 200 years ago, Nessera has not formed a complete magic research system, and most of them are still promoted by individual geniuses, and the development of magic in the past 200 years is not significant.

At least when it comes to making spellbooks, spellbooks from more than 200 years ago, or even the decades-old version used by Niya, are not much behind, and in some places they are more advanced.

This is Nya herself admitted, although it is impossible for Xia Duo to bring Nia's spell book to study it personally, but in addition to the content, Nia is also happy to exchange some information about the spell book itself.

In fact, most of the knowledge required to make a fine spell book is recorded in the Tower of Time, but there is no more complete summary version, and it is up to the makers to integrate it themselves.

And that's what Chardo needs.
