Hogwarts Summoning Manual

Based on the information Bai Lin has already obtained, there are many ancient gods who exist or once existed in the magical world. Their abilities vary, and some weaker ancient gods are not even as strong as top wizards like Dumbledore and Grindelwald. Most of them were destroyed in the struggle against the gods.

Several characters are quite well-known, such as Cthulhu and Hastur. Cthulhu is believed to have descended upon the magical world, but after his defeat, he was permanently sealed in an ancient underwater city. Hastur, on the other hand, did not descend directly, but instead sent his henchmen to cause trouble over countless centuries. Gracua is one of Hastur's new faction's lackeys.

During the previous time travel, Bai Lin was taken by Gracoya to R'lyeh, the ancient city that sealed Cthulhu. It had become an independent Earth instance. Gracoya's abilities made it impossible for him to break that planet-level seal. Of course, he wouldn't do something so thankless. He just wanted to use the power of R'lyeh's domain to suppress Bai Lin. If he failed, he would decisively change the battlefield.

If Hastur had left behind any relics in the magical world, Gracua would likely have used them first, whether to borrow his master's power or to show loyalty to Hastur. However, Hastur has proven to have little direct influence over the magical world, which is why Gracua can act with impunity here, revealing his ambition.

But the gates of the Dark Empire before us clearly belong neither to Cthulhu nor Hastur, and the information received from the summoning encyclopedia is also vague. Which ancient god does it belong to?

The illusion ended, and Bai Lin, enveloped in a faint golden light, slowly descended to the spot where Grakua had summoned the city gate. After a moment's hesitation, he decided to inform his comrades.

Bai Lin: [I have located Grakua's hiding place. He is badly wounded, and I intend to eliminate him completely. OVER]

Everyone was probably watching the team channel, anxiously waiting for Bai Lin's message. As soon as he sent it, his teammates responded one after another.

Yuxi: [Wait for us to come and support you! Don't go alone!]

Yan Nishuang: Are you confident?

Catherine: [Don't take too many risks! Summon me and Sifgar anytime.]

Lulu: [The time and space in the Ancient God Realm are very mysterious. It would be best if we gathered a team and set off together!] Lulu spoke in the team channel after a long time, clearly realizing that Bai Lin's information this time was extraordinary.

Hermione: [Professor! We should be able to help too! Our magic has been growing rapidly lately!] The "we" he's referring to likely includes Harry, Ron, Luna, Eddie, Neville, and other members of the Hogwarts team.

Bai Lin: [I'm very calm. The Ancient God's Domain isn't a battle area where everyone excels. Too many people will only distract us. Time is precious; I need to kill Grakua before he fully recovers! However, this battle may span many time and space dimensions, so please have faith in me!]

Yan Nishuang and Lulu asked almost simultaneously, "Do you mean we need to make other arrangements?" They were both meticulous and quick to understand. If it was just to prevent everyone from worrying, Bai Lin could have simply reported that he was safe and then joined the battle. The fact that he specifically informed them in the team channel meant that there must be other tasks that they needed to complete during the time Bai Lin "disappeared".

Bai Lin secretly praised his two confidantes for their understanding and consideration. They did not let their own feelings interfere with Bai Lin's judgment, but instead chose to follow his arrangements and complete other tasks within their capabilities.

Bai Lin [It's Fujiwara Eko. I don't trust her at all; I must eliminate her just like I did with Graccia.]

He then shared information about Fujiwara Eiko in the encyclopedia system.

Lulu: [Miss Granger, I'll take the Diana to Britain to pick you up!] If you're looking for a gambling ship at sea, the Diana is obviously a very suitable vessel, and she immediately identified a potential ally.

Hagrid: "Take me with you!" Bai Lin smiled. He had almost forgotten that Hagrid was also a member of the team.

Yuqian: [Sister Yan, let's meet at the habitat!]

Yan Ni Shuang [Arriving in 15 minutes.]

Bai Lin: [Alright then. Everyone, this battle is crucial, so please be careful!]

Yuxi: [Kairi...you too, please don't get hurt!]

Bai Lin: [Hmm]

Bai Lin put away the illustration book. He was afraid that if they continued talking, it would sound like a life-or-death separation, which would only increase his sadness and affect his mood.

He took a deep breath, took out the Sensing Relic, and smiled at the crystal-clear pearl in his hand: "You should be able to open this city gate, right, HF kid?"

After a few seconds of silence, the voice of the boy with his eyes closed finally echoed in Bai Lin's mind: "I will help you open this door... You must carry the Sensing Relic with you at all times, otherwise you may not be able to come back!"

Bai Lin nodded.

The sensory relic in his hand flew to the subway station entrance, and a golden light shone down on it. Bai Lin felt the ground suddenly begin to shake, and the air and clouds began to turbulent. It should be said that the entire physical space was shaking in this golden light.

"Damn, is it really that straightforward?" Bai Lin muttered.

He could see that the gates of this dark empire spanned different dimensions, and that Grakua had used the secret methods of the ancient gods to almost sacrifice the souls of hundreds of thousands of humans in Colombo in order to open the gates.

The boy with his eyes closed used his senses to transform the relic into a sword, directly piercing a hole in the spacetime barrier between the two planes.

Bai Lin couldn't help but feel even more wary of the boy with his eyes closed. This was a demigod living on the surface of a magical world, whose rank was probably comparable to that of the Silent One.

As the spatial tremors subsided, a spacetime rift opened. More like a crack in a wall, than a city gate or other form of portal, this rift resembled a blade cleaving through it.

Bai Lin glanced at the Sensing Relic in his hand, then rushed toward the spatial rift. But at the last moment before entering, he threw the Sensing Relic, this supreme treasure, out.

The young man meditating in the distance, with his eyes closed, surprisingly showed some expression. He frowned slightly, but soon returned to normal.

The relic did not fall to the ground or into the black water; instead, it vanished into thin air.

Despite having entered the time tunnel hundreds of times, Bai Lin still swore again; this feeling was anything but relaxed and pleasant.

Bai Lin cherished it, and even felt nauseous, because it proved that he was still a human being.

After the nausea subsided, he found himself standing on a platform made of obsidian.

The platform appeared to be built on a plain, surrounded by endless desert. Gale-force winds whipped up black sand, churning the wasteland like a locust plague. Some dark mountain peaks could be vaguely seen in the distance, and the sky was an eerie blackish-purple, devoid of sun, moon, and stars, but with enormous, unidentified creatures swimming through the high-altitude clouds.

The sandstorm reduced Bai Lin's visibility, but he still managed to find a special creation in the wasteland.

A very strangely shaped statue.

There was no majesty of the gods of order, no sinister aura of the underworld deities, and not even the indescribable nature of the ancient rulers.

It was a huge toad-shaped monster, with a big belly, a head like some kind of bat, and fur like a brown bear. It didn't look very intimidating, and Bai Lin even found it a bit ridiculous.
