Dotore from Genshin Impact is my teacher

(The author's mood is linked to their writing style)

(The protagonist only gave him the otherworldly knowledge he wanted, nothing about the continent of Teyvat.)

"You've got what you wanted, so hurry up and leave. I need to take a nap," Chen Xi said, issuing the order to leave.

"You don't like me? Aren't we the same?" The omega leaned closer to him, his breath tickling his face.

“It’s different!” Chen Xi retorted, pulling away from him.

Omega: "We'll meet again next time."

Chen Xi: "I don't want to. Get out of here."

Staying any longer would only be pointless, so the omega took the canned knowledge and left.

Forced to continue working, Chen Xi lay paralyzed on the bed, not wanting to move at all. He fell asleep while spacing out, and even the dozen or so slices working on him didn't wake him up.

...until the last slice came in and shook him awake.

"Child, wake up, don't sleep." The voice sounded like an old man's.

Chen Xi groggily opened her eyes and saw the slice of Doutore in his old age beside her bed.

Her light blue hair was streaked with white, her eyes were somewhat cloudy with yellowish whites, and her face was slightly chubby.

Chen Xi rubbed her eyes to make sure she wasn't seeing things: "Huh? Who are you?"

“You can call me ‘Old Man’.”

The "old man" had a slight upturn at the corners of his mouth, and his gaze was not so sharp, like that of a kind old man, if one ignored the bloodstains on his clothes and the faint smell of blood.

"What are you planning to do with me again?" Chen Xi showed the scars and needle marks that had been inflicted on her by other slicings while she was sleeping.

"You know how to use a gun, right? The original owner mentioned it."

"That depends on what kind of gun it is."

The "old man" smiled even more broadly and pulled a completely black pistol from his pocket.

"You made this?" Chen Xi was somewhat surprised, not expecting to see this on the Teyvat continent.

The old man calmly replied, "It's just a replica."

Chen Xi asked excitedly, "Whose work is this copied?"

The old man observed his expression: "Have you heard of Kanria?"

Chen Xi blurted out the words unconsciously: "A kingdom destroyed by the gods." Things were taking an increasingly unexpected turn.

"I know how to use it. Do you have ammunition?"

"Have."

The "old man" took out another bullet and handed it to him along with the pistol.

He took out the magazine, changed the bullets, put the magazine back in, cocked the pistol, aimed, and did it all in one smooth motion, just short of pulling the trigger on the "old man".

"Very good, it seems you are the person we are looking for."

"What? What do you need me for?"

"Your arrival here is no accident."

"You did this?"

"No, this is the fulfillment of the prophecy on the ruins of Kanria."

"What? What prophecy?" Could it be a trap that has been set up again?

"It's alright to tell you."

"Wait, let me try to see if this works."

Chen Xi pulled the trigger on the ground because he didn't know if the thing could be ejected, since it was something from Teyvat and should be different from what was there.

"Alright, that's quite powerful. Please continue."

"Kanria will be destroyed by the gods. Several hundred years later, people from another world, also a godless kingdom, will come to the continent of Teyvat. They can help Kanria restore its kingdom. These people have black hair, are very knowledgeable, and are skilled in using Kanria's sacred artifacts."

Chen Xi was shocked. Knowledgeable? He hadn't even graduated yet, and there were a lot of questions he couldn't answer. Was this what they called knowledgeable? It should mean that his knowledge covered a wide range of fields, but he only had a superficial understanding of each one. He really only had a superficial understanding of each one.

And is this thing some kind of Kanria relic? That's it? Did the developers change something again?

"So is there anything else?" Chen Xi wiped the gun barrel with his hand; this was a real gun, after all.

The old man: "[The clown] must really want to see you."

Chen Xi: "Him? The court mage of Kanria?"

"Old man": "In that case, there's no need for me to introduce myself any further."

Chen Xi: "Hmm, shall we go see him now?"

"Old man": "Yes. This is for you, as a gift."

Are all the Fools this generous? This is a real gun! Although I had touched my uncle's sidearm before, I only touched it and didn't dare to move it for fear of it going off accidentally. And now he's just giving it to me like this?

"Thank you for your kindness, I'll accept it." Chen Xi felt the heavy weight in her hand, which made her feel at ease.

Chen Xi put the gun back into his system inventory: "Where is [The Clown] now?" What is the Clown in charge of again? Forgot.

“I will take you to the side hall of the East Palace.”

The "old man" naturally took Chen Xi's hand, said a few words to Dotole (his true form), and then led him away from the laboratory, walking towards the East Palace.

After walking twenty li (approximately 10 kilometers), we arrived at the interior of a side hall of the East Palace. (You can refer to the Winter Palace in Russia for a similar view; I can't upload pictures right now because I don't have a computer.)

This was the coldest place in the entire Eastern Kingdom. Chen Xi was shivering from the cold. He took out a military overcoat from his system backpack and put it on, which warmed him up considerably.

"[Clown] I've brought the person you wanted."

The tall figure, who had been facing away from the two men, turned around. He was a middle-aged man wearing a blue mask covering his right cheek, with white hair and four-pointed star-shaped pupils. Just by looking at his eyes, one could tell he was a Kanriyan. His gaze was resolute, and he was wearing the uniform of a Fool's Enforcer.

[The clown] slowly opened his mouth: "Hello, person from another world, you should now be called fellow traveler."

Chen Xi: "Hello, fellow student?" This form of address sounds familiar, but it still feels awkward.

When the clown called Chen Xi "Tongshi," his heart skipped a beat. The pronunciation of "Tongshi" was a bit like "comrade," which almost caused Chen Xi to mishear it.

Tongshi (同士) Chinese translation:

Companion, partner, like-minded person; one with similar interests.

同士を集める／Gathering people with similar interests.

【名】

(People who share the same opinions, goals, ideals, hobbies, etc.) Like-minded people; comrades; fellow enthusiasts.

"Do you know how to use this?" [The clown] handed over the pistol and bullets.

"Yes." Chen Xi repeated the steps as before, his skillful technique making one wonder if he had a side job.

With the gun pointed at the ground, he pulled the trigger.

"Bang!" Flames shot from the muzzle, and the bullet flew out of the muzzle at an extremely high speed, embedding itself in the frozen ground, causing some cracks in the ground.

The clown clapped his hands: "Very good, you are the person I am looking for."

Chen Xi: "Do you still want this?"

The "clown" handed Chen Xi several boxes of bullets: "There are 20 rounds of ammunition left, and I'll give them to you along with this."

"Do you have something important to ask of me?" Chen Xi asked, knowing that the other party wouldn't give her something for no reason.

"Most of the people of Kanria have turned into monsters. I would like to ask you to help their souls find peace."

"I believe you."

Chen Xi's inner thoughts: But I'm not a Taoist priest! Do you have some misunderstanding about me? If it's a physical ritual to deliver the dead, then that's fine.

But I'll agree to this request because of the gun you gave me.

"Ok."
