After leaving the Vero Magic Shop, Eren returned to the family's castle and headed straight for the family's library.

Click, click, click......

Footsteps sounded in the dark corridor, and Iren rounded some bends and walked towards the library, where there was no light, and he used to need to hold some illuminations, but now that he has magic power, he can achieve night vision by condensing his magic power directly on his eyes.

"Eren is here......"

At the end of the gloomy corridor, there was a huge iron door, and on the lock of the iron door was a huge dragon head, when Iren came here, this dragon head actually trembled, and two faint blue flames lit up in the hollow eye sockets, and a dull voice sounded.

"Ancestor, I'm going to go in here and check out something."

Iren bowed slightly and bowed, the soul who stayed in the door paid respect.

This is a very old existence of Okmos, who refined his soul into it after his death, and became the caretaker of the library, and was an extremely powerful mage during his lifetime, with his soul guard, even if Earl Horn is not in the castle, he will not be invaded by the transcendent who is not a legend.

This is also one of the hidden defensive forces of the castle, after all, the Okmos family has too much background in this castle.

The iron door shuddered slightly, and a gap appeared in the middle, which automatically receded to both sides, revealing the exit.

The iron dragon head was also split in two, but the soul fire in the eye socket was not extinguished, and it seemed that it was still looking at Eren faintly.

Although there was no further response, Iren saluted again before entering.

The collection was extremely empty, with twenty huge bookcases containing all sorts of books, books bound on alchemical paper, ancient books of animal skin, carved wood, and books written in the leaves of life by elves in boxes......

The value of this knowledge, if it is released to the outside world, will be unimaginable.

All kinds of secrets, rituals, sights, spells, and battle skills...... There's it all in it.

At the end of the library, there is a wooden door engraved with chains and a large number of magic patterns, and behind the door is the knowledge stored by the Okmos family, but no one else will be allowed to enter without the permission of Earl Dohorn.

There is a lot of knowledge in it that can be called taboo, so taboo that even one's own people dare not easily let it be viewed.

To be honest, Iren was skeptical that if Okmos encountered some unstoppable disaster, Count Horn would directly take out a ritual to summon a sixth-order demon lord from it.

Although the door was sealed, it was made of extremely precious materials, the main body was a chain made of the hardest metal, and it was full of mottled marks, and even the wooden door, which was said to be made of the Tree of Life, looked dilapidated, and there were magic patterns engraved on the surface of the wooden door and iron cables around it, and some of them were dim, and even had a feeling that they were about to fall off.

In this world, there is power in knowledge, and what kind of filthy knowledge can cause this situation, Iren feels that his imagination is a little insufficient, after all, it may be too much, who makes the history of the Okmos family even surpass the time when the empire was established.

He thought so, and then walked between the bookcases, his eyes scanning the books to find what he was looking for.

Coming to a bookcase, he paused slightly.

I picked up a worn-out animal skin book and flipped through it.

……

The Play of the Fire Serpent –

Glass Giant Serpent: Devouring the earth, with a glass body, can rely on a glass-like body to burst out of strong light, and can create extremely high heat energy, can rely on devouring the earth and continue to grow, evolved from the spell Earth Serpent, added the activation spell to it, and added the blood of the gods, once caused a loss of control, was guided to the enemy, thus destroying a province, did not remain

Phantom Feather Light Snake: With the Philosopher's Stone refined by the attendant of the God of Light as the core, it can create a real illusion, and has the effect of purifying evil

Scorching Fire Serpent: Only strengthens the essence of fire, increases the degree of scorching, and finally completes the product as the Black Fire Serpent, which can even burn the magic power, and then inscribe the activation technique to remain

Iron Serpent: Forged by the bloodline of the rival family Sanas, it is forged by manipulating steel with its bloodline ability......

……

This is an account of the blood of Okmos in the past generations, and the play of their own fire serpent, and Iren may also write his own fire snake play on it in the future.

And the basic fire snake play will evolve to the end, and it will be engraved with the activation technique, which will be preserved, and become a kind of heritage of the Okmos family.

Among them, the powerful fire snake play is very big, and full of boldness, in the account of the time point in the early second dynasty, the records of these ancestors are quite normal, just integrate various elements into it, but in the later period, it began to change a little, especially in the later period, at the point in time when the second dynasty was about to collapse, the fire snake play of the ancestors of the Okmos family became wrong.

A lot of things related to the gods are used as materials, especially the Phantom Feather Light Snake and the Glass Giant Snake, the relationship between these two fire snake plays and the fire snake play is probably only named.

And these two kinds of fire snake play are extremely rare and powerful in the entire beast skin book, with a power almost like a natural disaster.

In the account of the Phantom Feather Light Serpent, when the ancestor describes the process of its formation, he mentions that a large number of madmen have been caused by the leakage of the power of the God of Light.

The thinking of this kind of fanatic people is distorted to the point that they only fanatically believe in the God of Light, and are willing to do anything for the sake of their faith, and this belief will constantly draw the power of their souls and transform it into the power of faith, according to a priest of the God of Light, the power brought by this belief is no longer the God of Light, but the light.

And the end result of these madmen is that their souls turn into nothingness and die.

Although the disaster caused by this is not as terrifying as the destruction of a province by the glass serpent, what is hidden in it is even more terrifying.

"The god of light, is it just the god of light? Doesn't it seem like the Lord of the Patrons of the day, that is to say, the attendants of the Old Gods? It seems that in that era, there seemed to be some rebellion against the old gods, but this part of the historical materials is very vague, and even in the religious texts of the new gods today, it is only more or less mentioned, and the stars of the old days fell in the past era. ”

"The old gods and the new gods are opposites, but why let the old gods leave some clues to let people know that they once existed? Would the gods really die so easily? ”

Eren thought so, but he sighed softly, knowing that this was beyond his knowledge, so he refocused his attention on the Phantom Feather Light Serpent.

He entered the library this time to find this animal skin book that recorded the evolution of a large number of fire snake plays.

He had roughly flipped through it and seen the description of the Phantom Feather Light Serpent, so he had some impressions.

In the Vero Magic Shop, he already has a basic first draft of the development of the future forces, but the most important question is who will manage it, after all, he has to cultivate most of the time.

So he thought of Chris, who was a good fit to help him do this, and a good excuse to make it easier for the legend of the Spiritual Grammarian Tower to do it.

After all, if something really happens, if you want that legend to help, it will cause too much unnecessary jealousy, attract some trouble, and even Theodore will secretly target him, but Chris is the descendant of that legend, and having him will undoubtedly have an extra layer of shield.

Of course, the specific role is not too big, and it can only be said that it is better than nothing.

But there are some things in the secret, Iren plans to do it himself, but next the school of Geas Academy is about to open, and he will cause a lot of trouble if he interferes in the affairs of the Northland again in the imperial capital.

So, in the end, he decided to use magic to solve the problem.

He was going to make a doppelganger.

But not an ordinary doppelganger.

"With the Philosopher's Stone refined by the attendants of the God of Light as the core...... Philosopher's Stone? ”

Yi Lun knew very well that he had never seen the words Philosopher's Stone when he read this book, and even the amount of information was not as complete as this time, which should be the reason why he became a second-order star species, so that the spirit of the ancestor who stayed in the library unsealed the hidden content of the book in his hand.

"If you use the technology of the secondary human in the future world to create a body, and then use the Philosopher's Stone as the core, can you create a clone?"

Yi Lun thought silently, thinking about such a possibility, in his Fire Serpent Play Beast Skin Book, it was clearly mentioned that the Phantom Feather Light Snake's Philosopher's Stone was the existence of the ancestor's soul fragments, which also made the Phantom Feather Light Snake have some problems, but it was only the leakage of energy, not the loss of control of the creation.

It's not like the glass giant snake that also uses materials related to the gods, but adds the activation technique, and it is directly out of control.

As a result, the ancestor could only guide it to the enemy, causing a terrifying disaster.

"But speaking of which, the ancestor who created the glass giant snake is still terrifying and ruthless enough, in addition to destroying a province, he also dragged a demigod, the strongest person in the sixth immortal rank, to die in the hands of an out-of-control creation in such a suffocated way, it really makes people not know what to say."

"Well, but the enemy ...... Is it the Second Dynasty? I remember that in the Second Dynasty, the Okmos family had the title of Marquis at its peak, and lived in the western border of the current Ion Empire, could it be that they were moved to the Northland because of this incident? ”

There are some areas of the family history that are very vague, such as why they moved from the south to the north.

Yi Lun actually still has some excitement about things like gods, and he even looked at this book and couldn't help but think that if he used the gods and sins as the material and the philosopher's stone as the core, would he be able to avoid things that would get out of control, after all, the glass giant snake appeared before the phantom feather light snake.

It is likely that the Phantom Feather Serpent is a complement to this path.

But it's a pity that in the follow-up records, there are very few fire snake plays related to the gods, and even except for the final activation technique, it has begun to continue the earliest atmosphere, no longer having the feeling of a terrifying biological scientist, but a step by step normal enhancement, and then inscribed the activation technique.

This should be related to the stability of the Ion Empire, although the Northland is cold, but the only danger of destruction is the invasion of the Northland by the Kingdom of Saian in the Far North.

But the crisis was eventually resolved by the stargazing tower in the middle of Campbell City, which is actually a terrifying mage tower.

In this way, it is likely that the bloodline of the Okmos family, which had become insane during the Second Dynasty, was cooled.

But because of this, Iren couldn't find more references.

He thought about it for a while, and felt that it was best to see the Phantom Feather Light Snake, which would allow him to have some more intuitive feelings.

After all, although the clone is just for doing things, if he can make the clone have strong abilities, it will be the best.

"Ancestor, I don't know where the Phantom Feather Light Snake is now? Does it still exist? ”

Eren asked softly.

There was a dead silence in the library for a while, and then the muffled voice of the Ancestral Spirit came: "The Phantom Feather Light Serpent has followed Mark. Okmos is gone, perhaps in some plane in the Plane Sea. ”

"Mark. Okmos? ”

Eren frowned, and a look of helplessness appeared on his face, this was not the ancestor who made the Phantom Feather Light Serpent, but his great-grandfather.

There's no way around it, the old man is still alive or not, he doesn't know it, and it's even more impossible to see the Phantom Feather Light Snake.

How can this kind of important family property be taken outside and wander around, and what should I do if I lose it? Was it great to be the head of the house once?

Well, you're amazing indeed......

Eren put back the beast skin book in his hand and asked again, "Can I know the specific method of making the Philosopher's Stone?" ”

"There are also things related to the Phantom Feather Light Snake, Ancestor, do you know what else is passed down in the family?"

After he finished asking, there was a dead silence in the library again.

After a long while, the Spirit of the Ancestors reappeared, and said very slowly, "Eren, are you interested in it?" It's a hoodoo, and the people of the Okmos family shouldn't be touching the taboos associated with the gods......"

"Ancestor, this is very useful to me, and I have some relationship with the gods."

Eren thought that he could die back anyway, even if he wasn't insured, he could go to the future in advance to see what his ending would be on this timeline.

With the handy ability of time, it's a bit of a waste not to learn to die.

"Forget it, since you're going to do so...... It shouldn't hurt to tell you, and it's really a wish of the Okmoth bloodline, and there's not much I can tell you......"

"The method of making the Philosopher's Stone should be with your father, only the previous heads of the family will know about it, there is no written record, as for the Phantom Feather Light Serpent, I remember one of its scales I saw on Willard's child."
