The role of "authority", in addition to the distribution of magic power and terrain changes in the library, also includes the authority of all knowledge - if you control the authority of the library, there will no longer be "forbidden books", but you can read them at will.
You won't be affected by the curse in the book even if you sleep on it.
As for the terrain change, it is relatively basic. You can only freely use the earth element of the library to reconstruct several libraries. It is no wonder that Budibog's sensors include the "earth element".
Of course, changing the terrain also requires mobilizing the magic power of its own library. This is why Budibog had no way to use this to stop Li Yue when he was ambushed - all the magic power was used by the Lord of Brain Spirit to heal his injuries. Where?
Is there any extra?
For Li Yue, using earth elements to change the terrain completely solved an urgent need and could greatly speed up the renovation of the library. It was exactly what was needed now.
Make a maze? Escape the room?
Traps such as bloody corridors, ground thorns, chandeliers and beam nets, combined with resurrectable brain spirits, should be able to meet daily needs.
As for the acquisition of authority, it is not easy to say, but it is not difficult to say - without being canonized by the Demon King, the only way is to eliminate the current owner of the authority and then hold a ceremony.
The more subtle point is that... although Li Yue has killed Budiberg's most powerful life, he has not yet completely eliminated him.
If you want to completely annihilate Budiberg's soul, you must destroy the soul altar; and if you destroy the soul altar, the brain spirits will not be resurrected, which becomes a paradox.
In Li Yue's vision, the brain spirits are the long-term defense force of the library. Being able to be "resurrected" is their greatest advantage. Should they be abandoned like this?
As for the content of the "ritual", it is relatively simple. It only requires the corpse of the demon under the previous control, plus a book, a handful of soil and a little candlelight, as well as a magic circle and a set of mantras.
The magic circle and the spell gate have told Li Yue that it is not very difficult, and the magic power consumed is within Li Yue's ability. Then the only question left... is how to deal with Budi Borg.
"Is there some way... to completely eliminate Budibog without destroying the soul altar in the library?" Li Yue had very high demands on Mento and was never satisfied.
Mento was silent - this was also the first time he saw a demon who had the ability to kill the area owner, but was unable to maintain the soul altar.
"What you are doing now...is a feasible attempt." Mento sighed, "Every time Budiberg is killed, his soul will become more fragile and his control over authority will also decrease."
"As long as you are the one who kills him every time, and keep it up... after enough time, the authority of the library will be infinitely close to yours, and it will be equivalent to being in your hands." Mento paused, "
And as long as you control more than half of the library, and then kill Budiberg and perform a ceremony, the transfer of authority should be completed."
Li Yue understood what Mento meant, and at the same time he also guessed something else - Budiberg was still the master of the brain spirit at this moment, and the authority still rested with him.
In this case... when there is no way to seize power in a short time, as long as you control him, won't everything be over?
Don't move the soul altar, kill Budibog once a day, transfer authority, and sign a soul contract with him to turn him into a follower; until halfway through, perform a ritual, and the library will be mine.
"That's it! Just sign a soul contract with Budiberg!" Li Yue suddenly realized, "You can let him still be the master of his brain and soul first. As long as he is mine, the library will also be mine.
"
"Do you understand soul contracts?" Mento could not completely read minds and could only see what Li Yue was thinking. Only now did he know Li Yue's plans.
It's quite a cunning approach.
"I read it in the book, thank you." Li Yue was grateful for Mento's blessing - without "absorbing", so many banned books would have killed Li Yue countless times.
"Ha, it's a joke, it must be a joke." Mento's reaction was that he thought it was funny, "Do you have any materials?"
Magic bat wings, Sintis snails, tabby gecko excrement... Li Yue thought about it and felt that there was still a chance. After all, Budiberg was only a low-level monster now, and the materials required were not very high-end.
"How about you give me some?" Li Yue didn't let go of Ximentuo's wool either - this guy was very stingy and showed no ill will, so he could only give it a try on the material.
"Do you think I'm that low-end?" Mento's way of saying "no" was very convincing. "Try it yourself. If I do it for you, you can die."
This is a simple logic - Mento wants to teach the devil, not become the devil himself.
"Understood." Li Yue thought it was worth a try, and he roughly figured out Mento's bottom line - he could provide help and knowledge, but he would not directly help Li Yue achieve a certain goal; and if what Li Yue did
What he does deviates from his expectations and may even exert some negative effects.
After a communication, Li Yue was determined to gain the authority of the library, and could even plan its future development in advance; as for the possible arrival of "high-level demons"... As long as Budiberg is not completely dead, there are still people pretending to be around.
space.
After solving the questions related to promotion and authority, Li Yue only had a few minor questions left. Taking advantage of the fact that Mento's cooperation was relatively high, he asked them all together.
"By the way, what's going on in the Thirteenth Library?"
The worm on Mento's chin twitched and he remained silent.
"There is a cloak on the altar. What is inside the cloak?"
The worm trembled wildly, as if snickering: "These two things, as well as the 'door' outside the upper level, are all choices related to your destiny. I will not give the answer."
Li Yue felt a little resentful. He regretted that he hadn't analyzed the door yet and couldn't find out his inner voice.
"Then... what are you going to do with this egg?" Li Yue changed the question.
Mento trembled like a worm again, and then solidified instantly. He said coldly: "Its growth... requires many kinds of materials. You can't afford materials that are beyond your contact range."
Li Yue thought to himself that it was indeed an egg summoned from another world, so noble by nature.
"Besides, you don't think... I only train you to be the devil, do you?" Mento touched his balls, as if they were born from him.
Li Yue was stunned - Co-author Dandan is also a candidate for the next Demon King?
It's not impossible... As long as we quickly sign the contract that represents a "benign relationship" - Li Yue was a little anxious, not knowing when Dandan would wake up.
"You know about the soul contract, and you want to sign it everywhere?" Mento confused the difference between the soul contract in this world and the contract given in the devil's illustrated book, and thought that Li Yue wanted to sign the former.
"Let me try?" Li Yue was really afraid that Mento would snatch the egg and run away.
"After this red hour, I will take it away." Mento only gave Li Yue one night to try, "before that, it is still yours."
"Okay, wake it up." Li Yue agreed decisively.
Mento happily awakened Dandan - this alien demon had no idea that when he woke up, he would already have a future without any worries and become the "closed disciple" of the Demon King's mentor.
"Come with me, we have something to discuss." Li Yue greeted Dandan to go out - he still didn't want to fully reveal the function of the Devil's Illustrated Book in front of Mento.
Mento didn't take it seriously: "Well, from now on, I will look forward to witnessing your journey."
The seven doormen waved to Li Yue in unison: "I wish you will take control of the library as soon as possible. I also wish you good food, sleep well, and happy killing."
