Dotore from Genshin Impact is my teacher

Dotore flipped through the catalog: "You want to learn this?"

“The student is dull, uh, he doesn’t understand anything.” Chen Xi couldn’t understand any of the science subjects, especially physics and chemistry.

Dotole noticed the dark circles under Chen Xi's eyes: "Staying up all night again?"

Chen Xi: "I can't sleep, and I have nightmares whenever I try to sleep."

Dotole: "What did you dream about?"

Chen Xi recalled: "The vengeful ghosts would come to claim lives, but I would wake up in fright every time I was about to see their faces clearly, and their temper was getting worse and worse, and they would want to chop people up whenever they saw them."

Dotore: "Them? Don't kill anyone lately, or it'll get more troublesome. Stay in the lab tonight, I'll keep watch."

[Skirmisher]: "When did Dotore learn exorcism magic?"

Dotole: "Of course I wouldn't, but you seem to."

[Scattered soldier]: "Then I'll reluctantly agree."

Chen Xi suddenly remembered the Taoist incantations he had memorized before. Although he wasn't very familiar with them, with the system as a cheat, it wasn't a problem: "I can suppress some of the evil spirits myself. A-San, help me prepare. We need a lot of glutinous rice and beans. We can't let them go out and harm others."

[Skirmisher]: "Okay, I'll go get ready."

Dotole: "Why are you calling me so affectionately?"

Chen Xi explained, "Teacher, please don't mind it, it's just a term of address between acquaintances."

Dottore: "You know Liyue magic? How come I didn't know that?"

Chen Xi: "I only know a little bit. I used to be a Taoist priest, but I couldn't beat the powerful Purple Fiend (Ghost King). I'll have to rely on my teacher then."

Dotole: "Okay."

It seems I still don't know him well enough; unfortunately, I can't find anything about him.

……

Chen Xi scattered the glutinous rice and beans that the [scattered soldiers] had brought on the ground, arranging them in circles, one ring after another, to prevent the vengeful ghost from escaping. Why beans? Because they didn't know where the ghost came from, so they could only try.

Evening

The bright moonlight shone through the window into the room, the wind howled, and the ever-burning fire in the stove had long since gone out, leaving only a deathly silence.

Chen Xi lay quietly on the bed and waited 10 minutes before falling asleep.

Looking around, it was pitch black, with dim lights flickering as if the power would go out at any moment. If I remembered correctly, this was the continent of Teyvat, and even the current level of technology in the Eastern Kingdom couldn't create something like this. It seemed I had entered a dream. Usually, ghosts in movies would appear on the roadside or in the house, which suddenly gave me a fright.

This road is familiar; it's the route I take home from school. I'll just follow my usual route.

Tsk, what's going on? There's something wrong with the surrounding scenery. Is it a ghost wall? Chen Xi found that the road that usually takes ten minutes to walk home now feels like going around in circles even after half an hour, and the streetlights are getting dimmer and dimmer.

It seems I've entered its "ghost realm." Let me find out where the real body is.

Chen Xi drew his sword from his waist and enchanted it with fire element.

Now you should be able to see the road clearly. The only thing that remains unchanged? Like: the streetlights? Or maybe that homeless man who's always sleeping? That doesn't make sense; how could there be a homeless man here?

"Let me try my knife. Fall down." Chen Xi wielded the knife with both hands and slashed at the homeless man, who dodged, and Chen Xi missed.

Turns out this ghost isn't stupid; it can even hide.

Then this scene unfolded: Chen Xi was chasing after the ghost, while the ghost ran ahead.

"You're running pretty fast! Stop right there!" Upon hearing this, the vengeful ghost ran even faster.

He chased it, but it couldn't escape.

After chasing for a while, the vengeful ghost stopped in an abandoned graveyard.

"Huff, you...you're running away? Why aren't you running anymore? You little trash." Chen Xi panted heavily as he mocked the vengeful ghost.

"You've fallen for their trap. Stay in Shibalipu!" A chilling smile appeared on the ghost's pale face.

Chen Xi: "So this is Shibalipu. No wonder there was a chilly wind blowing."

One by one, rotting hands emerged from the soil, and corpses burst forth, encircling Chen Xi and launching an attack, seemingly intending to wage a war of attrition.

"Is that all you're capable of? If I'm not mistaken, there are a few vengeful ghosts hiding around. You really think too highly of me."

The horde of vengeful spirits swarmed forward, shouting, "Stay here forever!"

"Well done! Try this move! Righteous Qi!" The knife in Chen Xi's hand grew larger, covered with incantations, and brought out bursts of golden light when it was swung.

The vengeful spirits were repelled, and several were killed on the spot, leaving only a wisp of smoke behind.

"Again!" Chen Xi became excited. His golden sword split into dozens of blades, which floated in the air, their blades pointing at the ghosts. With a thought, the swords seemed to have an automatic tracking function, chasing and stabbing at the ghosts.

After a full ten minutes, the vengeful ghosts all turned into wisps of smoke.

The scene in the dream began to change, and a misty creature pulled Chen Xi into a special space.

"Congratulations on successfully passing the Trial of Dreams."

"What are you?"
