Di Rock looked at Lu Junyi suspiciously, with disbelief written on his face.

In the middle of the night, he suddenly shouted:

"Where did you hide Xu Nan?"

Before Lu Junyi could explain, a big black net suddenly fell from the sky and caught Lu Junyi, the touch was very viscous and impossible to get rid of; What's even more terrifying is that his magic is also entangled in this sticky feeling, and it becomes very sluggish and sluggish!

"It's suspicious no matter how you look at it!"

Di Lock's expression was very serious: "No matter who your Excellency is, let's stay in the isolation room for a while......"

"Oh no, you seem to be a magician too? Maybe it's the basement designed by the demon that is more suitable for you. ”

Hearing the three words "basement", Lu Junyi jumped up from the ground like a cat with a fried hair:

"Listen to me, I'm really not Xu Nan."

"But I'm the son-in-law of the wizard king Bono and the husband of the princess of the empire......"

Mr. Captain was stunned for a moment, and then asked rhetorically:

"Which princess?"

Lu Junyi thought for a while:

"Three."

Dirock frowned and whispered:

"Neurotic! Run off at the mouth! ”

Anyway, he didn't care how Lu Junyi explained, he just dragged the cobwebs and threw him into the spaceship dungeon that was specially designed to isolate dangerous people.

Grabbing the fence of the prison door, Lu Junyi burst into tears:

"I just want to let the wind go."

Dillock, who turned to leave, paused, revealing a hint of thought:

"This tone seems to be a bit like that harassing phone call?"

"Forget it, no matter, it seems that strange things have been happening on the spaceship lately."

"Wait seventy-two hours and see again."

……

The Sacred Library, Basement.

The steam is thick and the sparks are shining.

The magic book spirits let out a low whimper, and they cowered in the corner, none of them daring to provoke the great demon king who was busy in front of them.

One grill, two steamers, pressure cooker, oven......

The tools Xu Nan took out from his dimensional pocket were enough to transform this not spacious basement into a makeshift kitchen.

And the ingredients, of course, are these poor magic book spirits.

"Hey, I can't help it."

"To be honest, if there is no other way, who would do such a thing like burning a qin and boiling a crane?"

"But I really can't comprehend these big truths, so I can only make this decision."

"If you can go to the world of the dead, don't blame me for being ruthless, after all, I'm not a devil, I'm just here to learn knowledge."

Xu Nan clenched his fists at the trembling magic book spirits, grabbed two screaming books casually, threaded them with a special metal pipe, and then grabbed several other books, skillfully threaded them into a string, and put them on the grill.

Sobbs can be heard on the grill.

The rest of the Magic Book Spirits were even more terrified.

But they had no way to resist, Xu Nan had the most terrifying aura of the magic book spirit, and when facing Xu Nan, the usually arrogant book spirits could only push each other like herbivores that had encountered natural enemies.

Xu Nan patiently put the string of book spirits on the shelf and roasted it.

Of course, he won't really burn it, but he just has to treat it with high temperature to dilute the spirituality of the magic book spirit.

In fact, according to the strength of gluttonous nature, ingredients of this level do not need to be processed at all, and they can be digested directly after swallowing.

But Xu Nan tried it and found that after eating the books with magic book spirits, it was easy to have diarrhea.

Moreover, the resentment of these book spirits will also make a gurgling sound in Xu Nan's stomach.

It makes me feel like I'm pregnant.

Xu Nan could only reluctantly use various kitchen utensils to deal with these ingredients first.

The main purpose is to get rid of its spirituality.

The spiritualization of magic books is not an uncommon thing, mainly relying on the accumulation of time, and it is not the same concept as the mana beast in the tide of aurora.

The Book Spirit is not strictly a life, but a manifestation of the personification of arcane power.

If you want to get rid of these nasty spirits, you just need to do a certain amount of damage.

There is no essential difference between roasting seriously and stomping on the ground a few times.

But Xu Nan is also a person with a sense of ceremony.

It took him more than a dozen hours to get rid of the spirits carried by the magic books themselves.

Then start eating silently.

[You have eaten "Magic, Energy and Assembly Line", your knowledge - magic industry experience +100]

[You have eaten the "Imagination of Mobile Mecha", your knowledge-alchemy-construction experience +600]

[You have eaten "Fifty-Seven Alchemy Techniques", your knowledge-alchemy-theoretical experience +999]

……

A large amount of knowledge poured into Xu Nan's mind.

But his mind is still very clear, and he doesn't get dizzy as he did before when he ingests a large amount of information.

It can be seen that the growth of mana has no direct effect on his inherent intellectual attributes; However, to a certain extent, it still gives him a bonus in related fields.

In layman's terms, with his gluttonous nature, he can eat books more happily without worrying about any sequelae.

This gluttonous feast took dozens of hours to eat.

Because knowledge is precious, he gnaws very carefully.

Xu Nan didn't dare to close his eyes, for fear that the night would be long and dreamy.

It wasn't until he had finished the magic book he had in his hand that he breathed a sigh of relief.

I have to say that the books that the Wizard King chose for Lu Junyi are all very classic magic books. Although Xu Nan swallowed dates, he also absorbed most of them, and so far, he has a deeper understanding and cognition of the magic industry system of the Arcane Empire.

"The Arcane Empire is indeed the pinnacle of human civilization in the general world, no wonder it can compete with the gods."

"In these books alone, there is a lot of wisdom, advanced ideas, and very correct guiding ideas."

"Although this knowledge cannot be directly transformed into considerable combat effectiveness, it will definitely be useful in the future development of Anonymous City."

Xu Nan was in a good mood.

Among these knowledges, the one he cared about the most was the knowledge of the dark side universe energy absorption circle. He'd heard Drift Fire mention it, and it was said to be a wonderful magic circle that could solve the energy problem of the Anonymous City.

But in the mouth of the flowing fire, this circle may be the source of trouble for the Arcane Empire.

In the past, Xu Nan must have scoffed at this statement, after all, he now understood the principle and construction method of this magic circle; But considering that Flowing Fire might be a ship soul at the level of the Zhushen Fleet, Xu Nan had to be more cautious about this technique.

"The so-called dark side cosmic energy absorption circle has actually been expressed very clearly in the literal word."

"The Arcane Empire has discovered a lot of strange universes outside of normal time and space, some of which are unattainable, some of which are unobservable but real, and only a very small number of outer universes can be touched by magic and technology."

"Among them, a parallel universe known as the [Dark Side] has attracted the attention of the Arcane Empire. They found traces of civilization in this universe, and even some traces of civilization that are closely related to this universe! For some unknown reason, their exploration of the dark side has been greatly hindered, but in other areas, they have made astonishing discoveries. ”

"The Dark Side Universe has a striking resemblance to this universe in terms of the frequency of energy flow!"

"Under the research of the Grand Arcanists, a technique of drawing energy from the dark side was invented, and it was soon vigorously promoted by the Arcane Empire, and was widely used in the major cloud climbing ships and floating cities."

"The energy drawn from the Dark Side universe requires only a very small amount of Category 3 metals and rare substances; And this energy is very strong, enough to support the consumption of various devices; At the same time, this energy source is also very clean, and its energy properties seem to be symmetrical with the universe, and generally after consumption, it will attract the matter of the world, and eventually disappear...... As long as you have enough garbage and dust next to the circle, it's just foolproof. ”

"With such a clean energy source in the hands of the Arcane Empire, it's no wonder that it was able to grow like that, and eventually became a big problem in the Heavenly Realm."

Xu Nan recalled what he had just learned and thought quickly:

"This circle doesn't seem to have any problems, and it can also dispose of garbage along the way, which can simply solve the eternal problems on the earth."

"But the Flowing Fire thinks it's a scourge, is it because of something wrong with its energy nature?"

"Or is it the Dark Side Universe itself, where there is a huge problem?"

Xu Nan didn't know this.

In the book he ate, there was no conclusive conclusion about this, only mentioning that there were also disagreements within the Arcane Empire at the time. Some people think that the dark side is very dangerous and should not be easily tabbled in; There are also those who believe that the dark side universe is a blessing left by the Creator and should not be wasted.

Now it seems that it is the latter view that prevails.

Originally, the Arcane Empire's research on the dark side should have continued. Unfortunately, the Great War broke out quickly, and a lot of research was delayed, and the Dark Side Energy Technology was not the only genius invention among them.

"I don't know where the current Arcane Empire has reached its research on the dark side."

"It's a pity that it's too hard to get some benefits out of that old fox in Bono."

One thing to say, Xu Nan is still very greedy for this technology.

The energy problems in the Anonymous City are even more serious than they have been revealed.

The momentary needs of these tens of thousands of people, Xu Nan can still find a way to solve it by himself, but this is definitely not a long-term solution. In order to become the top magical civilization city like Stephen Sand, he must have a strong enough energy foundation. Especially in Xu Nan's planning, Anonymous City must vigorously develop the magic industry in the early stage - which has higher requirements for clean and cheap energy.

"After I go back this time, I'm going to talk to Liuhuo."

He recalled the information about the technology again and finally made up his mind.

Next, Xu Nan had nothing to do.

In the basement, there is a book and a bed, and there is an old contact. He guessed that Lu Junyi was using this liaison to harass the Nova.

Xu Nan studied this liaison and found that this machine also came with a small receiver, so he put away the receiver, then found a pen and paper, and left some words for Brother Jun Yi.

This is for the sake of future contact.

finally got in touch with Brother Jun Yi, Xu Nan can't do nothing, continue to let Brother Jun Yi be alone in the basement of the library, right?

Otherwise, it is estimated that Brother Jun Yi will have one more basement PTSD in addition to the princess PTSD......

What's more, he needs these magic books a lot.

"I don't know what's going on with Brother Jun Yi?"

"With his intelligence, it should be a pleasure to wander around, right?"

Xu Nan thought optimistically.

Seventy-two hours passed quickly.

A wonderful energy entangled Xu Nan's body, and he knew that this was the end of the two-way summoning spell.

He didn't resist, but let that force drag him through time and space.

He doesn't need to consume mana for this action, because although it is a two-way summoning, it is actually Lu Junyi who has produced most of his magic power - as a level 19 industrial mage, Brother Junyi seems to have no other advantages, that is, there are many magic thieves!

After all, in the beginning, a big part of the use of industrial mages was to recharge the cloud ship......

Sou.

The scenery in front of me changes wildly.

Xu Nan grabbed the fence in front of him a little puzzled:

"Not ......"

"Why am I in the dungeon?"

……

The other side.

Lu Junyi sat on the bed with a grim face and shook his head.

The captain didn't listen to his explanation, and let him squat in the dungeon of the cloud ship for a full seventy-two hours!

It's too much of a failure!

But fortunately, Xu Nan did not disappoint him, not only cleaned the magic book in the house, but also left him a note for future contact.

This made Lu Junyi's mood suddenly improve a lot.

"It's still Xiao Nannan careful. I was so excited that I almost forgot about it. ”

"Otherwise, if he leaves that projection world, I will never have a chance to contact the outside world again."

Lu Junyi thought with some fear.

However, at this moment, a purple arbitrary door suddenly opened in front of him.

Lu Junyi quickly put away the old contacts and notes, and began to pretend to meditate.

"Huh? What about spellbooks? ”

A very sissy older baritone rings out in the basement.

It was one of the keepers of the Holy Library, the Grand Arcanist, Griffith.

Lu Junyi didn't speak, but pointed his finger at his temple very coldly.

He looked very cold, but in fact, he was pretending, and he was panicked, for fear that this old man would discover his two-way summoning technique.

"All of them have been understood and absorbed by you?"

The fat mage in the dark purple coquettish robe showed a surprised expression, but he didn't doubt it, just exclaimed:

"He is worthy of the man that His Royal Highness Bono and the three princesses have taken a fancy to!"

Lu Junyi breathed a sigh of relief in his heart, still unmoved on the surface, still pretending to meditate.

"Ahem, uncle, in that case, let's change places."

Griffith said with a pleasant face.

"Oh? Let's go! ”

He stood up with some impatience, as if to blame Griffith for interrupting his very devoted meditation training.

In fact, he has already blossomed a flower in his heart:

“MD！ Finally no longer have to live in the basement! ”

"Finally, I don't have to deal with those magic books anymore!"

Griffith casually opened an arbitrary door:

"This way, please."

"We're going to get a bigger basement......"

"Otherwise, I won't be able to let go of the second batch of six hundred magic books."

"Uncle? Uncle? ”

"Oh, what's wrong with you, Uncle?"

On the basement floor, a young man foamed at the mouth and had convulsions.

"It's okay, it's okay......"

"It's just that the meditation went a little wrong......"

He groaned weakly.
