My girlfriend is a demon

Chapter One: Forever Ravenous

Late autumn, night, a sky ablaze with stars.

Behind the ancient city, in an open-air campsite, a group of students preparing for the college entrance exams were celebrating their class monitor and campus belle's eighteenth birthday.

Li Sitong was indeed beautifully dressed tonight. The looks from the boys around her brimmed with youthful agitation; even those who hadn't harbored a crush on her before felt their hearts stir tonight.

Except for one boy named Jiang Xia, sitting on a folding stool, whose gaze at her was filled with peculiarity.

Three days ago, a message had appeared in Jiang Xia's mind—

**[Divine Sequence 001 – Undercover]**

Jiang Xia didn't know what it meant, but based on years of accumulated experience from TV dramas and novels, he surmised he had stepped beyond the ranks of ordinary people.

The first change this message brought him concerned Li Sitong.

Ever since this information appeared, he had sensed a familiar, kindred aura about her.

The feeling was hard to describe—like one beast encountering another, sniffing its scent: *Hmm, the smell checks out, it's one of my own.*

It was all rather baffling.

Furthermore, Jiang Xia had felt intensely hungry these past three days. No matter how much he ate, even to the point of vomiting, his stomach distended and full, a pervasive weakness from hunger still swept through his entire body.

He'd gone for a check-up at the hospital. The doctor found nothing wrong.

Jiang Xia had eaten a lot of barbecue tonight—no one had eaten more than him—yet now he could barely sit without effort, devoid of any energy.

He roughly understood that perhaps the message appearing in his mind had caused some change in him.

But no matter how he tried to explore it, the message remained just that—a message, unchanged.

If this continued, in a few days, his younger sister who loved feasts might get to enjoy the "Eight-Bowl Banquet" for her own brother.

"Everyone, raise your glasses! To our monitor's 18th birthday, forever 18!"

"Cheers!"

"Cheers~" Jiang Xia, eyes listless, looking like he might collapse at any moment, raised his beer glass and took a small sip.

The iced beer brought a cool clarity to his mind as it entered his mouth, but the next second, as it reached his stomach, a sudden discomfort seized him—a sharp, unbearable pain!

The feeling was like Sun Wukong entering his sister-in-law's body!

Not wanting to make a scene in front of so many classmates, Jiang Xia hastily stood up, dashed like the wind to a dark area far from the lights, bent over, and retched loudly.

A wave of murmurs rippled through the crowd.

"Damn, Jiang Xia, are you for real? One sip and you're like this?"

"Didn't you boast before about having a great alcohol tolerance, like facing the sea?"

"Back in my hometown, someone with this kind of drink capacity sits at the kids' table during New Year feasts."

By the time Jiang Xia returned, a boy was trembling before Li Sitong, receiving the "good guy card" she had just dealt him.

"I'm sorry, Xu Kun. I'm not planning on dating anyone right now. You're a good person."

"Besides, we only have a few months left before the college entrance exams. We should focus on our studies now."

Li Sitong wore a cream-colored down jacket, a red scarf wrapped tightly around her neck, paired with loose jeans and white sneakers. Her attire was neat, tidy, appropriate, and graceful. Her skin was delicate, fair, and smooth; she wore no makeup except for a glossy lip tint on her lips.

The title of campus belle and goddess was well-deserved.

Rejected, Xu Kun drooped like a frostbitten eggplant, head hanging low.

Unwilling to give up, he looked up at Li Sitong, mustering his courage, his voice trembling: "Li Sitong, I really like you..."

*Gag—*

As soon as the words were out, Jiang Xia made another retching sound and hurriedly turned to dash back into the darkness.

Xu Kun took a deep breath, gritted his teeth, and shot a resentful glare in Jiang Xia's direction.

Jiang Xia felt he was dying. This didn't feel like being drunk; his alcohol tolerance had never been this poor.

After that sip of beer entered his stomach, his entire abdomen felt like it was on fire, as if he'd swallowed sulfuric acid, not alcohol.

Three minutes passed before the situation slightly eased. Jiang Xia wiped the tears from the corners of his eyes.

In the dim moonlight, a bottle of water was handed to him beside.

He looked up. It was Li Sitong.

"Thanks." Jiang Xia unscrewed the cap, took two gulps into his mouth, swished it around, and spat it out.

"i***t!"

Jiang Xia froze.

Li Sitong's voice had changed. It was no longer its usual clear, sweet, and charming tone. Instead, she suddenly sounded like a queen wielding a whip?

In the slanting moonlight, Li Sitong's face appeared stern. Her voice was cold and crisp: "Don't you know we can't drink alcohol?"

Jiang Xia was stunned. At this moment, Li Sitong gave him the feeling of a completely different person.

Before he could internally process the meaning of her words, Li Sitong asked another question: "How many days have you been hungry?"

Jiang Xia's eyes widened in shock. *Li Sitong actually knows how many days I've been hungry?*

He wasn't sure what was happening to him, but he was certain Li Sitong must have become like him too. She had probably sensed that same kindred aura on him, hence her words.

"Three days. Hungry no matter what I eat," Jiang Xia answered weakly.

"Obviously. No amount of ordinary food will ever make us feel full." Li Sitong paused, her gaze oddly sweeping over Jiang Xia. "You don't seem to have realized what's happened to you yet."

Jiang Xia's expression stiffened. He was sure Li Sitong knew something.

He wanted to ask, to clarify everything as quickly as possible.

But the words reached his lips only to be swallowed back. He remembered the string of information in his mind: **[Divine Sequence 001 – Undercover]**

He was eager to get answers from Li Sitong, who seemed to be like him.

But he knew the word "undercover."

*Undercover*—one misstep could plunge you into an abyss!

Li Sitong gave a faint smile: "It's okay. It's fine if you don't know now. You'll understand after you've eaten your fill once."

"How do I get full?"

Jiang Xia asked a question he thought might not be dangerous.

Even if it was dangerous, he had to ask.

He urgently needed to be full. If he didn't fill his stomach soon, he felt he had at most two days left to live.

Li Sitong didn't directly give him the answer. Instead, she revealed a meaningful smile: "Don't leave after this is over."

Jiang Xia watched her retreating back.

As Li Sitong walked from the darkness back into the light, she transformed back into the pure, sweet campus belle goddess she was before.

Jiang Xia had a very bad premonition. The first reactions humans have to the unknown are always fear and unease.

What on earth is happening?

What is 'Undercover'?

What's the method to fill my stomach?

She said I'll know after I'm full. Know what?

And what is this 'we' she speaks of?
