I adopted a child demon from the Gap, and I'm a special agent for the Bureau of Supernatural Ab

Li Cheng watched the little girl staring at the fried rice, itching to eat, but she didn't dare to move forward because of his presence. He looked at her long, golden hair that shimmered under the light, at her clear, bright blue eyes full of longing, at her small but delicate face...

I will never leave her behind. I'd rather die out there than leave this girl here. That's right, once Kiritsugu Emiya has investigated, I'll send her somewhere else. Yes, that's decided.

Clearly, as long as Li Cheng remained in the living room, the girl wouldn't come over to eat. After thinking for a moment, Li Cheng turned and went into the bedroom next door. The room had also been damaged during the initial chase, but at least the bed had been preserved. Li Cheng entered the room, lay down on the bed, closed his eyes and pretended to sleep, while simultaneously straining his hearing to listen to the girl's every move outside.

Very light footsteps, circling around, forming a triangle from the bedroom door to the coffee table in the living room to the front door, taking quite a while. After more than ten minutes, he felt the girl's gaze from the doorway, clearly observing whether he had fallen asleep. She maintained her gaze on Li Cheng for more than ten minutes without blinking even once.

Are they treating me like SCP-173...?

While admiring the girl's perseverance, Li Cheng continued to pretend to be dead and asleep. Finally, he heard her leave, and her gaze disappeared as well.

The footsteps moved to the coffee table where the fried rice was laid out, pacing back and forth a few times, seemingly hesitant. Was she suspicious of the food? Or... did she lack even basic common sense about how to eat?

A soft sound—that was the girl climbing onto the coffee table.

Then came even fainter chewing sounds. Li Cheng then realized he had forgotten to put down his chopsticks, but she probably didn't know how to use them; in any case, she was eating with her hands.

She's a completely uneducated brat. Kids at this age are incredibly troublesome. Bringing her back was definitely a mistake; I should have notified Emiya immediately upon discovering her. Li Cheng, still lying in bed pretending to sleep, thought with a sense of unease.

The small, nibbling chews quickly turned into impatient swallowing. The girl was probably starving, or perhaps the food was just so delicious. Li Cheng heard her devour the plate of fried rice, finishing it completely in just a few minutes, licking the plate clean, and then licking her fingers with lingering satisfaction.

It seems my cooking skills are actually pretty good.

Li Cheng thought to himself with a touch of happiness.

After finishing his meal, he heard the girl walk to the door of his bedroom again, cautiously peeking inside. Li Cheng deliberately rolled over, immediately scaring the girl away. But after a while, the girl peeked her head out from the door again, looking at Li Cheng in the room with a mixture of fear and curiosity.

Then, Li Cheng turned his head, opened his eyes, and met the girl's wide-open eyes.

"Wow!"

With a gasp, the girl vanished swiftly from beside the door.

So you're still afraid of me? I went through all that trouble to make you a plate of fried rice. A little disappointed, but the thought of sending this girl away soon made Li Cheng feel better. Anyway, she couldn't escape this place on her own, so he might as well take a nap; he couldn't find anything else to do right now.

As Li Cheng was thinking this, he noticed that the girl peeked out from the door again, looking at him with curious eyes and a timid expression.

Turning her head to stare at him, she immediately whimpered and ran away. But even faster than before, she returned, poking her head out again and continuing to look at Li Cheng with curious eyes, like a timid kitten.

It really does look like a cat. Speaking of cats, golden hair, blue eyes. Golden, golden, orange, uh, an orange cat?

Feeling somewhat helpless about his tendency to overthink, he turned to look at the girl again, scaring her away for the third time. But this time, before Li Cheng could look away, she poked her head out again, boldly meeting his gaze and scrutinizing him from head to toe. Li Cheng could even clearly see the grease on the corner of her mouth.

Wow, you're getting bolder and bolder.

Li Cheng immediately made a motion to get up, and the girl screamed and ran away again, this time not daring to come closer for a long time. Relieved, Li Cheng lay back on the bed, changed to a comfortable position, closed his eyes, and began to sleep. Perhaps the series of movements had indeed exhausted him, and this time he quickly fell asleep.

As Li Cheng's breathing gradually became calmer and more even, the little girl once again stealthily moved to the door, peeking cautiously at Li Cheng inside.

After watching for a long time, and probably confirming that Lee Seung-jin had fallen asleep, the girl immediately began searching the entire house for a place to escape. However, the unmoving doors and windows, along with the incredibly hard floors and walls, left her with no way to escape. Undeterred, after trying for several hours without success, she yawned, looking somewhat tired, jumped onto the sofa, curled up into a ball, and closed her eyes.

Soon, the sound of snoring could be heard from the sofa. A figure peeked out from the bedroom door, stared for a moment, and then disappeared. Soon after, the sound of snoring could also be heard from inside the bedroom.

The first night of our first meeting ended with a messy room and two people sleeping soundly—a relatively peaceful ending, to some extent.

……

In my dream, I excitedly stretched out my foot, only to wake up to find my toenail embedded in my flesh, blood flowing all over the bed, and the wound on my toe turning black. Damn it.

Writing about emotional interactions is really difficult, and I guess I'm not very good at it. I can only try to improve slowly and hope to get more support from readers.

Section 5, Chapter 4: Legendary Monsters

Although he initially promised to reply as soon as possible, Kiritsugu Emiya disappeared for three whole days. For three whole days, there was absolutely no news of him, leaving this incredibly troublesome little girl to Li Cheng.

For Li Cheng, the past three days spent with the little girl had been an extremely terrible experience.

Face-to-face communication was completely impossible. The girl clearly didn't know any language at all. When facing Li Cheng, she could only make threatening gestures like "roar," "hiss," and "ha," and then scream "ya!" and "wah!" and run away when Li Cheng approached. She was extremely wary of others, or rather, of Li Cheng, and would never give him a chance to get close.

Not only that, she also likes to wander around, often messing up the house. Li Cheng has to clean up the furniture she knocks over from time to time, which is quite troublesome.

Moreover, in order to take care of this girl, Li Cheng had to cook for himself every day. He did consider ordering takeout, but after careful consideration, he decided to cook for himself since the food wasn't very nutritious for a child. However, although the girl was willing to eat what Li Cheng made, she would only eat it when he wasn't around, or at least not in front of her. And since she couldn't use chopsticks or forks at all, she would just grab the food with her hands and put it directly into her mouth, and she would often accidentally knock over the plates and break them.

She didn't care about personal hygiene at all. Her mouth and hands were always greasy after eating. Once, Li Cheng couldn't stand it anymore, so he spent more than half an hour catching her after turning the entire living room upside down. He wiped her mouth and fingers clean, and she bit and scratched him several times during the process. He only managed to endure it by sheer physical strength.

But after the next meal, she made herself all dirty again. Li Cheng, who had finally tidied up the living room, looked tired and decided to let her be.

This feeling... I feel like I'm raising a wild kitten. It completely refuses to communicate with people, runs around wildly, and attacks by scratching and biting. Even though I'm responsible for its three meals a day, it always acts fierce towards me.

Just thinking about all this gave Li Cheng a headache.

Well, the only advantage is that Li Cheng doesn't have to scoop her poop. The most amazing thing about this girl is probably that she doesn't need to go to the toilet like normal people. Yes, although it sounds disgusting, it's a reality we have to face. Normally, even the most beautiful and charming young girl will have to defecate in the toilet. And depending on the situation, there will be differences in color (black, yellowish-brown, brown, green, etc.) and states (thin, thick, long strips, broken strands, etc.).

The topic seems to be getting interesting (covers nose).

However, this unknown girl seemed to have no need for this function at all. She had a huge appetite; no matter how much food Li Cheng gave her, she could eat it all without losing her figure. She would even lick the plate clean after each meal, looking as if she wanted more, making it hard to imagine how much she could eat. However, she never showed any sign of needing to use the restroom. Li Cheng even considered the possibility that she didn't know what a toilet was and was just messing around, but he searched the entire house and found nothing.

Could it be that she has the ability to completely digest food? That's impossible, isn't it?

Unconvinced, Li Cheng didn't leave the house for the entire third day, keeping a close eye on her whereabouts. As it turned out, the girl really didn't go to the toilet even once.

Even if there's a meat grinder inside her stomach, there should still be bits of meat coming out. Could this girl's stomach contain a black hole or some other dimension?

In short, after wasting a whole day confirming this fact, Li Cheng was somewhat disappointed—but how could he be disappointed by something so inexplicable? In any case, he decided to ignore this trivial matter, since it wasn't really that important anyway.

Lying back on the sofa, Li Cheng watched the sitcom on TV with an indifferent expression and yawned slightly.

The girl squatted in front of the television, staring intently at it with a serious expression. Her long, golden hair, reaching to her chest, swayed slightly, and her azure eyes were fixed on the screen, unblinking. In fact, Li Chengben didn't like watching television. It was only after discovering the little girl's interest in the content that he started turning it on every night, randomly selecting some relatively wholesome programs.

Whenever this happens, the girl who used to run around everywhere will come to the TV, sit down quietly, and watch the TV intently. Sometimes she's so engrossed that she doesn't even hear Li Cheng get up and leave behind her. But no matter what the content on TV is—tragedy or comedy—she always maintains a quiet demeanor and shows no emotional reaction.

What a strange little brat. Humph, I guess I'm a weirdo too, since I picked up this weird kid.

It was a rare moment, aside from sleep, when both of them could have some peace and quiet. Li Cheng lay quietly on the sofa, dozing with his eyes closed, while the girl sat quietly in front of the television. There was no boisterous chasing, no cautious hostility; this was the only time Li Cheng felt affection for this little girl.

I wonder how she views all of this?

The phone at his waist vibrated; someone had sent a text message. Li Cheng opened his eyes, took out his phone, and saw a very simple message from Kiritsugu Emiya.

"It has been confirmed that it is downstairs."

These are indeed very distinctive sentences.

Li Cheng sat up from the sofa, stretched slightly, and then stood up. The girl was still engrossed in the television in front of her and didn't notice Li Cheng's movements behind her.

"Hey, I'm leaving now."

Shouting loudly, he finally startled the girl sitting in front of him. She was so frightened that she jumped onto the TV cabinet and turned around to look cautiously at Li Cheng standing in the doorway.

This kind of reaction is normal.

He waved to her deliberately, then opened the door and went out.

During those three days, he went out several times, and the girl knew that the door could be opened. She even learned by observing Li Cheng's actions that she had to turn the doorknob to open the door. However, merely observing the actions was not enough to understand the underlying principles. After Li Cheng locked the door with the remote control, there was no way she could open it.

Therefore, several shallow fist marks were left on this extremely hard door.

Ignoring the girl inside, Li Cheng went downstairs and immediately saw a dark figure standing silently outside the building, a single red spark standing out starkly against the darkness. It was Emiya Kiritsugu, the deputy leader of Li Cheng's action team and a longtime friend, waiting for him downstairs.

Li Cheng hurried downstairs, while Emiya Kiritsugu didn't waste any words and turned to leave. The two men walked silently in the darkness until they stopped in a deserted alley nearby.

"The results of the investigation... aren't they a bit worrying?"

Emiya deliberately chose this location, which likely indicates there is indeed some problem. Li Cheng's expression gradually became serious, and he couldn't help but start thinking about what was wrong.

"It's hard to say, take a look first." Emiya stubbed out his cigarette, exhaled a puff of white smoke, took out his phone, and showed Li Cheng some information.

"This is... a lab report? Blood components, a magical structure? No corresponding structure found? Fantasy species components? No similar species found? This..."

As Li Cheng slowly flipped through the documents, his brows furrowed more and more as he read on.

"Does this mean she's not human, but a fantastical creature left over from a past era?"

Li Cheng inquired.

“No,” Kiritsugu Emiya shook his head. “As you can see, in terms of the corresponding structure, she doesn’t correspond to any known fantasy species.”

"Could it be a newly discovered species?"

“No,” Kiritsugu Emiya interrupted Li Cheng again in a serious tone, “Even if it is an undiscovered new species of fantasy, at least there can be similarities in the basic genetic structure. The key is that the genetic structure is completely different. The little guy you picked up is not a species at all with the fantasy species.”

Not the same species?

Li Cheng was a little confused. Besides humans and the fantasy species that once existed on a large scale but are now endangered, what other species in this world could have high intelligence and high combat power?

“So, I checked it carefully again and finally came to a general conclusion,” Kiritsugu Emiya said, pulling a thick stack of documents from his clothes and handing them to Li Cheng. “That child is probably a monster.”

"Huh? A monster?!"

Li Cheng was shocked.

"Shouldn't monsters and such be things like rural legends and tales?"

He felt he must have misheard.

"No, youkai do exist, primarily in East Asia, including this island. Unlike the powerful fantasy species of the past, they are strange creatures born from human fears and other complex emotions, and they will completely perish once forgotten," Kiritsugu Emiya began his explanation.

"In the past, those who transcended others cared little for ordinary people, and powerful groups like magicians and warriors rarely cared about the lives of ordinary people. Technology had not yet developed, and humans were extremely fragile. Fear of nature and fear of things that could not be understood gave birth to all sorts of strange monsters. Some were friendly to humans, some were hostile to humans, and there were even man-eating monsters. Their numbers and types were quite complex."

"Some yokai, over time, developed higher intelligence, began self-cultivation, and gradually broke free from their dependence on human fantasies, becoming powerful beings similar to fantasy species. However, many more yokai acted on instinct like animals. As human technology gradually developed, magicians and martial artists began to share their power with ordinary people, and superpowered individuals, products of modern technology, emerged. Human fear began to disappear, and those yokai lost their means of existence and began to perish."

"Especially after the Great Sage Ares, one of the transcendents, spearheaded the widespread sharing of cultivation methods for those powerful forces 120 years ago, humanity as a whole began to grow stronger and stronger, eventually becoming the most powerful beings on Earth. The monsters also began to decrease in number and eventually disappeared completely."

While flipping through the records about yokai and listening to Kiritsugu Emiya's explanation, Li Cheng roughly understood what yokai were. Then, new questions arose.

"But right now, it's only proven that her genes are different from those of humans and fantasy species. There's no evidence that she's a monster, right? Does that mean that besides humans and fantasy species, only monsters are left?"

"In the headquarters' gene bank, there is a blood sample of a monster from a hundred years ago. It was obtained by the Transcendent One by strengthening the fixed concept. It is also the sample of what we once thought was the last monster in the world. I hacked into the headquarters system, infiltrated the gene bank, found that sample, and compared it with that girl's."

"You mean..."

"The difference is huge. Compared to that girl, that blood sample is as simple as a paramecium. However, it is certain that they still have similarities. To be more specific, that girl is a paramecium that has evolved for a million years. Although it is a completely different species from the original, similarities can still be found in the most basic aspects."

Will the monster whose blood sample was taken cry if you describe it like that...?

"In short, she is a monster, and as it stands, she is still a young monster."

Emiya Kiritsugu made a summary.

"Well, aside from that, there's nothing special about her, right? What should we do with her next? We need to notify headquarters to provide her with living and educational support..."

"No, not yet," Kiritsugu Emiya interrupted Li Cheng without hesitation before he could finish speaking. "Cheng, don't you understand? She is someone who has long since disappeared from this land, someone who should never have existed. But now she has appeared, and regardless of her own thoughts, this world will inevitably be shaken by her. Whether she likes it or not, she will definitely bring change to this world. And change means sacrifice..."
