Chapter 20

With Lu Yun by his side, Yun Qi never worried about going hungry. He was fed very well every day, and sometimes when he ate too much, his tail and horns would uncontrollably stick out.

Yun Qi dodged Lu Yun's kiss, feeling waves of heat rising from his spine. He knew something was wrong and pushed away Lu Yun, who was confused about what was happening. "I'm going to the restroom."

Yun Qi arrived at the restroom, locked the door, lifted his clothes, placed his hand on his tailbone, and frowned. The next second, a thin, entirely black tail with an upside-down heart-shaped tip swung out. Yun Qi looked at the tail that had appeared, then touched the top of his head, and sure enough, sharp horns had also appeared.

Lately, I don't know what's wrong, but his horns and tail keep popping out uncontrollably. Could it be because he's been consuming too much yang energy?

He had never experienced this before. Yun Qi reached out and tried to put the tail back, but after reciting the incantation several times, the tail remained unchanged, wriggling restlessly in his palm.

Yun Qi had been in the restroom for too long, and Lu Yun was worried that something might have happened to him. She walked to the door, looked at the blurry figure inside, and asked, "What's wrong, Xiao Qi?"

"Are you alright? Is something wrong with your body?"

Yun Qi panicked when he heard Lu Yun's voice, grabbing his tail and not knowing where to put it. He looked at the figure outside the door and was glad that he had locked the door. Otherwise, if Lu Yun came in and saw his tail, he wouldn't know how to explain himself.

Yun Qi swallowed hard, trying to make her voice sound normal, and said, "It's okay, I'll be out soon, it's just that my stomach hurts a little."

Lu Yun squinted. Why did he see something dark swaying back and forth behind Yun Qi?

Lu Yun asked hesitantly, "Are you really alright, Xiao Qi?"

Afraid of being seen, Yun Qi quickly turned her back and said, "It's okay, really it's okay."

Lu Yun returned to bed, still wondering what that long, dark object was.

A few seconds later, an idea flashed through his mind: Xiao Qi was a succubus. He had seen images of succubi online, and they seemed to have a tail behind them.

To verify his guess, Lu Yun searched for images of succubi online. There were all sorts of images, from anime to live-action to movies and TV shows, which was dazzling.

But only one thing firmly caught Lu Yun's eye: that long, thin black tail, with a pink, upside-down heart at the end.

Succubi also have sharp fangs, a pair of bat wings, and pointed horns on their heads.

Lu Yun's breath hitched. He zoomed in and out on the pictures on his phone, comparing them to Yun Qi in the bathroom. Finally, he smiled, unable to believe how beautiful these things would look on Yun Qi.

Just as he was chuckling, Yun Qi, who was struggling with his tail in the bathroom, finally managed to put it back and pressed down on the top of his head, also pushing back the protruding horns.

Looking at himself in the mirror, who looked exactly like a human, he felt a little worried. What was going on?

He was fine before; he never lost control of the tip of his tail. If this continues, wings will sprout too. If Lu Yun finds out, how will he explain it?

Yun Qi, who had just left, also looked worried. He didn't hear Lu Yun talking to him. He took out his phone and logged onto the Demon Realm's network to ask other demons if they knew what was going on.

Seeing that he was ignoring him, Lu Yun walked over and leaned on his leg, which startled Yun Qi so much that he almost hit his face with his phone. In order to prevent Lu Yun from seeing what he was searching for, he quickly turned off his phone.

"What's wrong?" Yun Qi controlled her flustered expression and tone, trying her best to sound the same as before.

Lu Yun asked, "What were you doing in the bathroom just now? Why didn't you come out?"

Yun Qi made up a random excuse, "My stomach isn't feeling well. It's probably because I've been eating too many different kinds of food these days."

Lu Yun hummed in response, staring intently at him. Her hand wandered to Yun Qi's tailbone, her burning palm pressed against his skin, making Yun Qi sit up abruptly. He looked down at Lu Yun in a fluster, hearing her ask, "Really? Xiao Qi, you're not hiding anything from me, are you?"

Yun Qi almost blurted out that he was a succubus in his panic, but he managed to hold back at the last moment. He chuckled awkwardly, "Of course not."

He dared not look into Lu Yun's eyes, as if Lu Yun already knew something. A hand was gently rubbing his tailbone from behind, making his tail feel hot and like it was about to pop out again. Yun Qi panicked and quickly pulled Lu Yun's hand away: "No, stop rubbing. It's getting late. Let's rest. We have to go to work tomorrow."

Lu Yun's eyes darkened. It seemed that Yun Qi still intended to keep it from him and was not going to tell him his true identity. When would he be willing to tell him?

Is he not working hard enough? Is his performance not good enough? It seems he needs to step up his game.

Lu Yun nodded, leaned over and kissed Yun Qi's cheek: "Okay, then we'll rest. Goodnight."

Yun Qi said tentatively, her voice trembling slightly, "Good night."

The lights were turned off, and the whole room went dark. Yun Qi was still awake. He listened carefully to Lu Yun's breathing beside him. After listening to his breathing gradually become steady, he called his name softly a few times. After confirming that Lu Yun was asleep, he secretly picked up his phone, first put it on silent, and then turned the brightness down to the lowest setting.

He searched on the Demon Realm Browser to find out why his sharp horns and tail kept appearing despite not lacking yang energy.

The internet in the Demon Realm is a bit slow. Yun Qi bit her lip anxiously, watching the phone screen spin for several minutes before the first answer finally appeared.

Why do succubi's demonic parts, such as their tails, involuntarily protrude when they have abundant yang energy?

Yun Qi's eyes lit up. Wasn't this talking about him? His finger trembled as he clicked on the link. A long explanation followed, but Yun Qi ignored it and scrolled to the bottom. It read: "[Absorbing too much yang energy has caused internal demonic energy imbalances, ultimately leading to death by explosion. If you have these symptoms, you have no more than three days left.]"

Yun Qi was stunned, staring blankly at her phone, the words "no more than three days left" echoing in her mind.

What? Only three days? Didn't the demon tell him that succubi would do this if they consumed too much yang energy? Dad never mentioned it either.

Yun Qi's hands trembled more and more as he looked at the screen. He had only been with Lu Yun for a few days, how could he not live much longer?

Taking a deep breath, Yun Qi exited the page and continued scrolling down. When she came across an ad with the exact same title as the one above, she clicked on it with trembling hands, praying that it wouldn't have the same result as the one above.

Skipping over the fluff above and looking straight to the final result, Yun Qi held her breath, staring at the tiny line of text.

If a succubus loses control of its tail, horns, etc., when it has abundant yang energy, it indicates that the succubus is about to undergo its second evolution and enter adulthood.

Yun Qi was taken aback. Adulthood? Wasn't he already an adult? His human age was already over twenty.

As soon as the thought came to mind, Yun Qi knew something was wrong. He was an adult human, but he had never heard of any adulthood for succubi. He was already so big, he should be an adult, right?

Unable to come up with any results on his own, Yun Qi figured his father was probably still awake, so he sent him a message.

"Dad, I can't control my tail and horns lately; they keep popping out. I looked it up online, and they say I'm entering some kind of adulthood. Is that true?"

Yun Qi figured that his father must not be asleep at this time. Sure enough, his father replied less than a second after the message was sent.

Yes, are you an adult yet?

Yun Qi was taken aback. There really is a period of adulthood?

But haven't I already passed adulthood?

[Haha, silly child, you haven't reached adulthood yet. It must be that Lu Yun used his yang energy to bring you to adulthood. You've been consuming demon-made yang energy, which has little nutritional value, which is why your adulthood has been delayed. Now that Lu Yun's yang energy is nourishing you, your adulthood should arrive normally.]

[This is all normal. I originally calculated that you wouldn't reach adulthood for at least a few months, but I didn't expect it to be so soon. It seems that Lu Yun is quite capable.]

[Our diet changes during adulthood; simple yang energy isn't enough anymore, we need semen. Have you and Lu Yun done it?]

Yun Qi blushed: "We don't have a father yet, and we all feel like we haven't spent enough time together..."

"It's been quite a while, almost a month now, hasn't it? Your father and I had only known each other for a week when we did everything. Reaching adulthood isn't a big deal, but you need to be careful these next few days. You'll be extremely hungry, even your yang energy won't be able to satisfy you. Also, it's normal for your tail and horns to appear; during this time, we succubi are prone to losing control."

[There's nothing else to worry about. Okay, I'm going to eat now. You figure out how to get Lu Yun in bed.]

Yun Qi didn't send any more messages. It was obvious what kind of food they could have so late.

He carefully put down his phone, looked at Lu Yun sleeping beside him, his Adam's apple bobbing up and down. What should he do?

He and Lu Yun haven't even taken things to the next level yet, and he's already asking for semen? How is he supposed to bring it up? What should he do?

Yun Qi was so worried about coming of age that the whole of Shanghai was on edge, fearing that if she were with Lu Yun, her tail would uncontrollably pop out the next second.

But after a week, his tail didn't show up much, which made Yun Qi think that his adulthood was over, and he couldn't help but relax.

Moreover, he didn't seem to have any of the symptoms his father had mentioned, such as not having enough yang energy to fill his stomach. On the contrary, he was exactly the same as before.

Days passed quickly, and a week went by. Yunqi had completely forgotten about adulthood. He didn't care about anything his father had said and thought that adulthood was over.

Until one day, on a weekend, Yun Qi was half asleep when he felt waves of heat surging through his body, almost engulfing the entire city of Shanghai. At the same time, his stomach, which had been filled with Lu Yun's yang energy before bed, felt incredibly empty and was screaming for food.

Yun Qi clutched the tail that had sprouted behind him, his legs trembling as he went to the bathroom. Oh no… his adulthood… had arrived…
