Harry Potter and the Old Ones

This library was carved out bit by bit after being completely hollowed out with a kind of black stone.

The stone itself is not very hard, but it can inconceivably be able to isolate most of the Old Ones' prying eyes other than the Outer Gods.

As long as there is no active connection, the outer gods cannot affect any living beings inside the stone.

This is why the race of the great Yith chose to build this library of almost all dangerous knowledge in the universe inside this stone.

According to Merlin's records, this stone belonged to another native race of the earth at that time, a kind of intelligent crustacean higher life like an upright crab. After the great race of Yith discovered the magic of this stone, the two sides jointly established the library.

But because the aborigines of the earth at that time did not have the knowledge as great as the race of the great Yith, this joint museum was blessed with three kinds of magic by the race of the great Yith.

One is called knowledge, and every intelligent life that visits this place can face knowledge directly through words.

One is called time, and every intelligent life that has visited this place has the same number of opportunities to avoid madness as the fingers of one hand.

There is also a kind called sacredness, which comes from the specific sublimation of the stone itself, and any polluted spirit cannot enter this library.

These are three great magics, which have not dissipated even after countless years of honing.

And the reason why it is set up like this...

Because the race possessed by the great Yisi race at that time had seven fingers, their allies, the kind of upright crab-like crustaceans, had pincers in their hands, which counted as two fingers, while their mortal enemy, the flying worms, Not even a single finger...

But even so, it cannot completely eliminate the influence from the unspeakable existence.

There are existences that exist independently of the fourth dimension, far beyond the limits of human comprehension.

These two magical blessings, according to Merlin's guess, may be used by the race of the great Yisi to overcome research problems.

Whenever a certain research reaches a dead end, the race of the great Yith will arrange a ceremony outside the library to contact a great being in the universe, most of which is Yog-Sothoth, one of the three pillar gods Avatar of Tawil Yat Umr.

This Outer God, representing the benevolent side of Yog-Sothoth, sits on the huge stone pedestal behind the first silver key gate of the ultimate abyss of the universe. He is willing to bestow endless knowledge on any living being who can pass through the silver key gate——

As long as they can bear the weight of that knowledge.

When the researchers of the race of Great Yith were driven mad by the incarnation of the One-of-All and went back in time, there was always a great deal of knowledge left in their souls that they could take in themselves.

It's like when Tierra was contacted by the outer god corresponding to "The Seven Chapters of Xuanjun", two kinds of magical magic marks were left in his soul.

This magical blessing called "Time" can save them from facing Azathoth and the Three Pillars God directly, or fighting passionately with other Outer God level old rulers.

In the eyes of the group of academic masters of the great Yisi race, this ability is for further exploring the truth of the world, not for saving their lives in the hands of the old rulers.

It's a pity that Tierra wasted such an opportunity.

But Merlin is much more reckless than Tierra. At least Tierra is from modern society. He has passed the postgraduate entrance examination in the last university and is familiar with Cthulhu Mythos, so he only wasted one chance.

At the beginning, Merlin lost three fingers at the beginning.

By the time he really understood what it all meant, it was too late.

This also caused Merlin, the famous great magister, to encounter extremely serious mental pollution from the outer gods in his later years. It was so severe that he seemed to have completely become another person in his later years, another crazy, cruel, and unreasonable humanoid monster.

He wrote down the contents of the parchment Tierra was holding in his hand when he was awake for the last time as Merlin.

"A wise man who does not belong to this time and space, a traveler from another world, I predicted your arrival..."

"I try my best to stay sane and write the following text..."

"Don't use up your five chances..."

"Don't try to contact the race of Great Yith, at least until you are on the same latitude as them..."

"You can choose the Supreme Mother Goddess..."

"If you can, please come to me. I put my coordinates on the third shelf on the fourth floor, but please don't try it lightly before you get the divine latitude."

"If I take the initiative to contact you..."

"Hide in, hide in the library, I can't get in..."

After reading this passage, Tierra folded her hands silently.

Hope people are ok.

Don't contact me if you have anything to do.

Tierra rummaged through a few more parchments, this time not just looking at the beginning, but reading the whole thing.

Since Merlin predicted his arrival, with the mental state Merlin was able to enter this library at that time, he should not have left anything deceptive in his notes.

At least from this point of view, he can read with confidence.

It has to be said that the notes of a great magician are quite helpful to a rookie like him who is new to magic, especially Merlin himself, who grew up from a farm boy who could not read a word to a generation of great magisters. Starting from how to guide one's own magic power, and then to the essence of magic, it can be considered almost everything.

Tierra stared at the parchment in her hand.

"Yujadili, Ur, Osalia." Tierra recited the spell silently in her mind, and at the same time gently opened the parchment with both hands.

The parchment seemed to pause in the air and then fell down.

This is the levitation spell recorded in Merlin's diary, the simplest and most suitable spell for beginners to guide their own magic power.

Although Tierra successfully cast the cursed worm before, the cursed worm is an instinct engraved on the soul by the outer gods. Before he learned to guide his own magic power, the source of the power of the cursed worm came from his spiritual power, rather than relying on himself magic.

Therefore, he also needs a simple magic to guide his own magic power.

"Yuja Dili, Ur, Osalia." Tierra read out this time.

The parchment in his hand seemed to have a tendency to break free, but the parchment still fell after Tiye stretched his hand.

...

"Yujadili, Ur, Osalia." After about forty or fifty attempts, the parchment in Tierra's hand finally floated tremblingly in the air.

But after more than ten seconds, the parchment fell down quickly.

And Tierra also felt a chill all over, and collapsed on the chair as if exhausted.
