The call-out interface, in appearance, is in the form of a hologram, but it is still the style of a physical book. There are realistic covers, title pages, table of contents, text, notes, etc., which can be flipped through and manipulated according to your mind.

On the thick cover, a simple image of a giant is carved. On the giant's torso and limbs, there are five slots each. Four of them were empty, with only a glowing rune embedded in the slot in the left hand.

Click on the rune on your left hand with your mind, and a dialog box pops up, which reads [Open Permission: Spellcaster, Allow to unlock catalog chapters 38714-76200. 】

Click on the View button to open some of the pages mentioned above. It is said that it is partial, but in fact it is ridiculously large, there are tens of thousands, after all, it is an e-book;

Flip through one of the pages at random, and it's full of dense small print and graphics. Most of them are academic papers, research reports, experimental records, etc., and most of the content is about the properties and principles of various magic. The spells that Oster secretly learned before can be found in the corresponding literature.

If this is only one-fifth of the whole book, if you read the whole book from beginning to end, I am afraid that it will not take you several years to read it. It's not a book at all, but a huge database no less than an electronic library on the other side of the planet, thanks to the intelligent search function.

That's all Oster can see at the moment. After clicking on several other empty slots, [XX part of the authority is insufficient, forbidden to be consulted] will be displayed, and the corresponding book page cannot be opened.

The names displayed in the four empty slots are: Torso - Immortal; Right hand - the sword-bearer; Left foot - the enhancer; Right foot – the tricker. Together with the "caster" of the left hand that has been activated, it just forms a complete body;

Oster couldn't help but wonder what would happen if he collected all five runes and inserted them into the card slot—could he summon a dark archmage? Quickly shook his head and skewept the stage.

In addition, next to each card slot, there is a graphic that looks like an energy bar. The energy bar next to the "spellcaster" in the left hand has just been charged a little, and the other card slots are naturally empty.

Based on the experience of playing games all his life in his previous life, Oster has basically understood the meaning of these constructs;

Each of the five slots should represent the ability to view each section of the book, and more content can only be unlocked if you find similar runes and insert them into the corresponding empty slots.

Since unlocking the part called Spellcaster already gives Oster the ability to parse and copy spells, the other parts should also correspond to different abilities.

As for the energy bar, it doesn't mean unlocking progress or upgrading experience, can the ability still be upgraded? Where are the runes that aren't on the empty slots?

After studying it for a while, Oster realized that the rune in his left hand could actually be cut off, so he took the rune out of the card slot by his mind and brought it to his eyes to take a closer look.

I didn't find anything when I turned it over, it looked like an ordinary stone with a colored symbol carved on it.

Disappointed, Oster put the rune stone back. However, the moment the stone was inserted back into the card slot, the book trembled, and then a half-length image of an iron giant was projected.

It was none other than the high-definition real version of the giant on the cover, and the calm voice sounded immediately.

It is a language that Oster does not understand, with mixed pronunciation and simple words, and the lingua franca, dwarven language, and elven language that Oster inherited with this body seem to have the shadow of this language.

As the e-book on the side popped up the decoding interface, after reading and converting, clear meaning began to enter his mind, and the giant's words became understandable;

"Comrade you have never met, you can see this message, which proves that you have obtained the initial recognition of the magical intelligence in the book, and have joined our great journey. In this crusade to burn the old world, all the order of exploitation and oppression will be burned, and a new world where everyone is equal will be reborn from the ashes. ”

It's like some kind of pre-recorded footage that plays back once the slot is home. Oster watched and listened, his mouth opening wider and wider;

If he hadn't known in advance that this was the Warcraft universe, and he was holding the Book of Sargeras, he would have thought that this giant with a steel face and body was a certain pillar brother - whether it was the voice or intonation, it could not be said that it was exactly the same, it was simply the same!

“…… For tens of thousands of years, since the Naylan Conference, when the Burning Revolutionary Army broke with the Pantheon, scientists of the Revolutionary Army have been searching for a spell-casting system that can be used by mortals; Let magic, the ultimate power in the universe, no longer be monopolized by the Titans, and let the people of all races on all planets have the power to resist oppression and pursue happiness.

In front of you is an encyclopedia of the principles of magic and the history of the universe, with details and laws of almost all existing spells and magical phenomena. Although my name is fortunate to be on the cover, it is not the achievement of one person, but the collective wisdom and hard work of countless outstanding researchers.

My fellow Titans, my erstwhile Titans, are very adept at fashioning themselves as benevolent communicators of order. As you may have heard, they refer to energy that is not within the Source Forge system as chaotic energy, and spells as unholy magic. The area that was liberated by the revolutionary army and no longer had a hierarchy was called the Twisted Void. As for the demons, it is also customary to call each other between the two classes whose contradictions are irreconcilable. But I believe that the evaluation of everything needs to be made with one's own eyes;

Marton, Karesh, Nailan, Argus, Dergo, Azeroth...... Every planet that the Titans have set foot on has gradually depleted the energy of the Star Soul under the predatory mining of the Source Energy Furnace. In a land where the soul of the world has completely withered, there will be no crops sufficient to sustain life; Even if it looks the same, it's just dust that collapses at the touch of a touch......"

Hearing this, Oster suddenly thought, depletion, dust, isn't this the crop disease that the west is encountering? This footage was recorded tens of thousands of years ago, to say the least, and it seems that something similar has happened more than once. Mr. Sa's video continues to play;

"This magic book is a memory made based on the improved Titan Data Disc technology. Forgive me for restricting access to book content, not out of arrogance and mistrust, but because I've learned that knowledge is a double-edged sword;

It's like the Titans built a brilliant civilization with the most advanced technology, but used it for killing and oppression. At the time of the catastrophe of Argus, I realized that in the hands of noble people, knowledge is a tool for production and construction, but in the hands of people with ulterior motives, knowledge can be a weapon of destruction and destruction.

So I've sealed away forbidden knowledge that would normally only be used for military purposes, or that has great hidden dangers, and left it under the care of the magical intelligence in the book. It will only allow unlocking this part of the content if it deems that the holder's purpose is sufficiently legitimate and noble.

Finally, I would like to tell the book's custodians that once you unlock all the permissions, you'll be able to discover one of the true secrets hidden in the book. Forgive me for not being able to say more, I was going to protect it myself, but it was a bad luck. The crimes I committed as an accomplice of the Titans will not disappear by themselves no matter how many years have passed, only I can make amends; A final decision must be made between me and Al-Mansour.

Comrade, by the time you read this message, I may no longer be in this world. Don't grieve or hesitate for anyone's loss, nothing is immortal, only our faith and cause live on. ”
