Poor caster was killed by Ye Yu neatly before he appeared for 10 minutes, maybe this can be selected as the fastest exit in the history of the Holy Grail War. However, although Marshal Gilles left the scene, the Illumination City Textbook, which was his treasure, was still intact.

Of course, because of the world's corrective power, it is difficult for this thing to be kept in reality for too long, even if Ye Yu's magic power helps to resist this corrective force. But anyway, it didn't take a long time, Ye Yu opened the entire book and read all the things recorded in it one by one, and then lifted the forcible residence of this treasure and let it leave this world with Gilles.

"Hmm...... Isn't it really a famous magic book under the Cthulhu system...... This thing's requirements for mental power are a bit too high. Recalling the text he had just read, Ye Yu inevitably rubbed the corners of his forehead with his hand with a headache, thanks to the fact that the soul origin of his doppelganger was connected to the body, otherwise I am afraid that he would have gone crazy just now...... Is it true that there is a price to be paid for forcibly acquiring high-level knowledge?

"But fortunately, everything has been written down, and then I will recompile this thing according to my own understanding, it shouldn't be so much consumption, really...... These outer gods always use such a crude way to record knowledge, aren't they afraid that no one will be able to inherit it in the future? "Generally speaking, reading a magic guide book requires mental power, but for a magician like Ye Yu who has mastered the law, when compiling a magic guide book, some restrictions will be deliberately added to it, so that people who meet the spiritual power standard can read the true meaning of it, and in the eyes of ordinary people, it is completely an ordinary book.

The advantage of this is that even if it is handed over to a mage apprentice who is just getting started, he will be able to use the book to learn little by little, and gradually decipher the knowledge recorded in the book by enhancing himself. The magic guide book that Ye Yu left to them back then used this principle.

But like the book in my hand is very rough, as long as I start reading, I can't help but let myself fall into it, and the mental power is constantly consumed and it is difficult to withdraw at all, if the mental power is insufficient...... In addition to gouging out his eyes, there is only one end where his head is blown out. Probably this is the most striking characteristic of the guys under the so-called Cthulhu system, who especially hate those who try to gain knowledge that they can't control.

But then again, the reason why Ye Yu coveted this Luoyan City Textbook was not to obtain the knowledge inside, in fact, he intended to use it as a medium.

After all, Shi Chen's side couldn't count on it, but if he wanted to build a favorite magic array, he still needed a lot of necessary raw materials, so Ye Yu had no choice but to take the risk of making a deal with those old rulers......

In fact, speaking of the old rulers, ancient gods, and outer gods under the Cthulhu system, for people like Ye Yu who can travel in the void, they are actually all called outer gods, and there is no such detailed division at all.

The reason why they are called such a term is purely because the gods of the Cthulhu system themselves are creatures who have the ability to travel in the void, and have left the world they originally lived in to live in the void.

For example, if Ye Yu is an adult, and he divorces Qi and is expelled from Qi's world, then he can actually be regarded as a member of the outer gods. Of course, such a situation cannot happen at all~~

It is conceivable that these outer gods are all very powerful without exception, and there are vastly different personalities and strengths, and some of them will connect with the rest of the world when they are bored, although they can't directly enter the world like Ye Yu, but they can also rely on their huge spirit to have a certain impact on the creatures in the world, and even develop faith through this.

This Luoyan City textbook is undoubtedly the mark left by one of them in this world.

"That's ...... It's done~~" He closed his eyes and slightly recovered his mental power from before, and soon when he opened his eyes again, there was a heavy book in his hand...... It was the Luoyan City textbook he had just made using projection magic, but the content in it was written by Ye Yu in an ancient script in Emile's world. Words themselves have power, and they are enough to suppress the evil intentions of the book itself.

"Then let's get started without further ado...... But before that, I think I should change places. I was busy recording the lucky book before, but I didn't think it was until everything was over, and Ye Yu remembered that the scene in front of him was not suitable for a long time at all. After peeling the spell off Ryunosuke's hand with a gloomy face, Ye Yu wiped out the entire building with a single fire, and he ran to an open field on the outskirts of the city before the police arrived.

Except for a magic circle that isolated the breath, there was no need to prepare much, and then Ye Yu held up the copied version of the Luo Annihilation City Textbook with his left hand, and pressed his right index finger against the cover of the book to immerse himself in it. The process is similar to using meditation to communicate with all things, and Ye Yu, who had practiced the Blade Zen technique, quickly connected with the vast soul behind the book through this book.

According to the general theory, it is very dangerous to communicate directly with the outer gods like this, and some accidents will occur if you are not careful...... Of course, it's not just the outer gods, it's dangerous to have such an exchange with every law-level guy, and if you change to an ordinary soul, I'm afraid you will be burned by the law directly.

But Ye Yu, who was standing behind the three world wills, naturally did not have this concern, and he himself was not weak enough to need the protection of others, so Ye Yu released his kindness and tried to communicate with the other party at the first time on the link between them.

What he didn't expect was that the other party replied quickly, and the most important thing was that it sounded ...... It's not as powerful and domineering as rumored, right, it's better to say ......

"Hey~~ I'm the chaos that always sneaks to you with a smile on my face, Nyara Totipe greets you~~" The voice on the other side sounded quite energetic, and I don't know if there was some kind of problem when they switched languages, how to ...... Does that sound cute?

Not to say the Cthulhu guys...... Are they all tentacle monsters?! (To be continued.) )
