Harry Potter and the Great Old Ones

This library is completely hollowed out of a black stone and carved out piece by piece.

The stone itself is not very hard, but it is incredibly able to block the prying eyes of most of the Old Ones except the Outer Gods.

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

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

According to Merlin's records, this stone belonged to another native race of the earth at that time, an intelligent crustacean advanced life similar to an upright crab. After the great race of Yis discovered the magic of this stone, both parties

jointly established this library.

However, because the indigenous people of the earth at that time did not have as knowledgeable knowledge as the great race of Yis, this joint museum was blessed with three kinds of magic by the great race of Yis.

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

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

There is also something called sacred, which comes from the sublimation of the specificity of the stone itself. No polluted spirit can enter this library.

These are three great magics that have not faded away even after countless years of hard work.

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

Because the race possessed by the great race of Yis at that time had seven fingers. Their allies, the upright crab-like crustacean creatures, had pliers on their hands, which counted as two fingers, while their mortal enemies, the flying worms, had

Not even a finger...

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

Some existences are independent of the fourth dimension, far beyond the limits of human understanding.

According to Merlin's guess, these two magical blessings may be used by the great race of Yis to overcome research problems.

Whenever a certain research reaches a dead end, the great race of Yis will arrange a ritual outside the library to contact a certain great being in the universe. In most cases, it is Yog-Sothoth, one of the three pillar gods.

The incarnation of - Tawer Yat Umr.

This outer god, who represents the benevolent side of Yog-Sothoth, sits on a boulder pedestal behind the first Silver Key Gate of the ultimate abyss of the universe. He is willing to bestow endless knowledge on any creature that can pass through the Silver Key Gate.

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

When researchers of the great race of Yis are driven crazy by the incarnation of the One who unites all things and go back in time, there will always be a large amount of knowledge left in their souls that can be accepted by themselves.

Just like when Tiera was contacted by the foreign god corresponding to the "Xuanjun Seven Chapters Secret Scripture", two magical magic imprints were left in his soul.

This magical blessing called time can be saved except when confronting Azathoth and the Three Pillar Gods, or in a passionate confrontation with other Old One rulers of the outer god level who seek death.

In the eyes of the academic masters of the great race of Yis, this ability is to further explore the truth of the world, not to save lives in the hands of the old rulers.

It's a pity that Tiera wasted an opportunity like this.

However, Merlin was much more reckless than Tiera. Tiera was from modern society after all. She had passed the postgraduate entrance examination in college and was familiar with the Cthulhu mythology, so she only wasted one opportunity.

Merlin lost three of his fingers at the beginning.

By the time he truly understood what all this meant, it was already too late.

This also led to Merlin, the famous great mage, encountering extremely serious mental pollution from foreign gods in his later years. It was so serious that in his later years, he seemed to have turned into a completely different person, another crazy, cruel, and unreasonable humanoid monster.

During his last waking moment as Merlin, he wrote the contents of the parchment Tiera is holding in her hand.

"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 awake and write the following words..."

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

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

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

"If you can, please come to me. I have put my coordinates on the fourth floor, No. IIV bookshelf, but please don't try it easily before you obtain 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 paragraph, Tiera silently clasped her hands together.

Hope everyone is okay.

If you have any questions, don't contact me.

Tiera rummaged through a few more pieces of parchment, this time no longer just reading the beginning, but reading the entire page.

Since Merlin predicted his arrival, then based on Merlin's mental state when he was able to enter this library, 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 coming into contact with magic for the first time. Especially Merlin himself grew up from a peasant boy who couldn't read a word to a great magician.

Starting from how to channel your own magic power, to the essence of magic, it almost covers everything.

Tiera stared at the parchment in her hand.

"Yugadili, Ur, Osalia." Tiera recited the incantation silently in her mind, while gently releasing the parchment with her hands.

The parchment seemed to pause in the air for a moment before falling down.

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

Although Tierra had successfully cast the cursed worm before, the cursed worm was an instinct engraved on the soul by the outside gods. Before he learned to guide his own magic power, the source of the cursed worm's power came from his mental power, rather than relying on himself.

of magic.

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

"Yugadili, Ur, Osalia." Tiera read out loud this time.

The parchment in his hand seemed to be trying to break free, but it still fell down after Tiera stretched out her hand.

…

"Yugadili, Ur, Osalia." After about forty or fifty attempts, the parchment in Tiera's hand finally floated tremblingly in mid-air.

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

Tiera also felt a chill all over her body, and slumped on the chair as if she was exhausted.
