Xia Yan couldn't understand why his self-control seemed to disappear whenever he was in front of Xiao Hei. After thinking for a long time, he finally figured it out. It was because she was just too good... Every movement and expression of hers exuded various charms. Plus, she could understand his inner thoughts, knowing exactly what he wanted. Unless he could truly attain a state of desirelessness, he would never be able to resist her temptations.

At this moment, Xiao Hei was resting in Xia Yan's arms after they had just engaged in an intense battle. It wasn't that Xia Yan was tired, but rather, he was worried that pushing further would harm Xiao Hei's body, so he decided to let her rest for a while. With Xiao Hei nestled in his embrace, her fingers lightly traced circles on his chest, murmuring, "To do such things to a pregnant wife, Master, you truly are an incurable pervert."

"...Are you even in a position to say that? Who seduced whom first? I'm starting to suspect that you're not a dragon but a succubus!" Xia Yan retorted.

However, to his surprise, Xiao Hei, who would usually argue back, didn't refute him this time. Instead, she asked with a hint of curiosity, "Master, do you like succubi?"

Although Xia Yan often referred to Xiao Hei as a succubus, he had never actually seen what a real succubus looked like. In his imagination, a succubus was someone dressed provocatively, extremely beautiful, and possessed demonic features like horns and a tail. They could captivate others with just a glance. Xia Yan scratched his cheek, feeling a little embarrassed as he replied, "Well, I wouldn't say I like them, but I think comparing you to a succubus is quite fitting... After all, I can never resist your allure."

Xiao Hei couldn't help but burst into laughter, covering her mouth with a playful chuckle. "What do you mean by 'I can never resist your allure'? Clearly, it's what you wanted! Besides, you haven't really seen what a true succubus looks like, have you?"

"Well, no, I haven't. So what?" Xia Yan replied.

"In that case, let me show you what a real succubus is like," Xiao Hei teasingly said.

With her words, the lights in the room went out once again. What happened next would become an unforgettable memory for Xia Yan... At this moment, Xiao Hei was gripping Xia Yan tightly with her hands and clamping her legs around his waist, refusing to let him pull away, even though he was already at his limit. Then, a voice filled with ultimate temptation reached his ears, "Master, I'm about to go. Please grant me your everything!"

In the end, Xia Yan couldn't resist her onslaught and let his desires pour out like a torrent. - - - Just as Xia Yan thought that he had satisfied her and that everything would be over for tonight, suddenly, a pained expression appeared on Xiao Hei's face. She curled up on the bed, trembling uncontrollably while holding onto her body. Xia Yan instantly became extremely worried, thinking that she was feeling unwell, and anxiously asked, "Xiao Hei, what's wrong? Are you in pain somewhere? I'm sorry... if only I could have restrained myself from my impulses earlier..."

Xia Yan blamed himself, thinking that it was his momentary impulse that caused her such pain. But in the next second, the holy rune imprinted on Xiao Hei's abdomen emitted a bewitching red light and rapidly changed its shape. Her hair and skin color also underwent a transformation, with her originally dark purple hair turning into a swift silver-white, like snow.Her fair skin quickly turned into a wheat-like tan, as if it had been sunburnt.

At the same time, a long and slender demon tail grew from behind her, and the horns on her head became longer and more curved than before.

After all these changes were completed, Xiao Hei Yin's painful expression gradually disappeared, replaced by a look of great enjoyment.

She sat up, stretched her body, feeling an unprecedented sense of ease!

Xia Yan looked at her transformed appearance with some confusion and asked, "Xiao Hei, are you okay?"

"Of course, my dear master, you have fully activated the succubus blood in me~"

"Huh? Succubus blood? What is that?"

"Master, do you not remember? I mentioned before that I once devoured a succubus during the great battle. After digesting her, I gained her power. When the World Tree recreated my physical body, it also brought forth this power. Originally, this power was extremely weak, but because of the ** we had, it became stronger within me. And now, you have completely activated the succubus blood within me... In short, I have become a succubus through and through!"

After hearing this, Xia Yan stood frozen in place.

Originally, what he said was just a joke, but who would have thought that one day, the joke would actually become reality!

Xiao Hei Yin had really transformed into a succubus!

And a succubus with black skin and silver hair.

Next, Xiao Hei put on a camisole nightgown and slowly walked to the window.

As she walked, unknown liquid occasionally dripped from her body onto the floor.

Xia Yan knew exactly what it was, causing his cheeks to slightly blush.

As for what happened next, it was the scene at the beginning.

"Master, you are the one who turned me into this. I believe you will take responsibility for me, won't you?"

Xia Yan felt his throat become dry as he looked at her. He swallowed and murmured to himself, "But I never thought things would turn out like this..."

"Xiao Hei..."

"You won't be permanently stuck like this, right?"

Actually, his biggest concern at the moment was this question. She should care a lot about her dragon lineage.

If she were to remain like this forever, wouldn't he become a sinner?

However, her response relieved him, "Master, don't worry, I don't mind being a succubus... Besides, I didn't say that I couldn't change back after becoming a succubus."

"....Huh, you can still change back!?" Xia Yan asked in surprise.

"Of course, in strict sense, my current state is more like the awakening of my succubus bloodline... Usually, as long as I don't use this power, I will still be a dragon, but once I use it, I will become a succubus... And also..."

At this point, a shy expression appeared on Xiao Hei Yin's face, as if what she was about to say was extremely difficult to say.

"What else?"

"...And also, after awakening the power of the succubus, I may need to absorb your essence as my food every day... I was wondering, can you provide me with food every day, Master?"

...

"I thought it was something else. Rest assured, since it was me who turned you into this... I will definitely take full responsibility! My essence, you can absorb it however you want."

Xia Yan patted his chest and made a promise to her, but he seemed to have underestimated the complexity of Xiao Hei Yin as a succubus.

"In that case, I won't be polite!"

Xiao Hei Yin's eyes flashed with a bewitching charm, and immediately she used 'Seduction', causing Xia Yan to lose consciousness almost instantly.When he finally snapped out of it, he found himself engaged in unspeakable acts with the succubus Xiao Hei. At the same time, he could feel his life force being rapidly drained by her. It was as if she wanted to completely squeeze him dry, leaving nothing behind. However, even as a succubus, she was still incredibly cute! Even if she were to drain him dry, he would probably do so willingly.
