My senior sister is not a human being!

She licked her red lips while looking down at Su Yuchen: "Stinky brother, what are you hiding from?"

"..."

Su Yuchen was silent for a moment and then asked, "I suddenly realized that you are actually half a succubus."

"That seems to make sense." Cristiana smiled and said, "Do you like it?"

"I like it, but..." Su Yuchen emphasized: "You don't want to suck blood now."

"I really don't want to." Christia pushed her hair behind her ears and leaned over to whisper in his ear: "But I just like you so much and I miss you so much."

Su Yuchen raised his hand and gently stroked her back. Just as he was about to speak, Jiang Xiyu came over and said lightly, "I'm addicted. I can't live without it. I can't live without it."

Just three short sentences contain a lot of information.

Cristiana's expression froze, and she glared at her in shame and anger: "If you have changed into your school uniform, go to school quickly!"

Jiang Xiyu looked at her blushing cheeks calmly: "Do you know what you look like now?"

"What's wrong with me hugging him?" Cristia retorted: "It's not like I want to do anything else..."

Before she finished speaking, Cristia's eyes widened as she looked at the shape of Jiang Xiyu's mouth. "How dare you say I'm burning..."

As he spoke, he was about to stand up, but then he sat back down as if he remembered something. He raised his hand to comb his long hair and said charmingly: "That's me, what's wrong?"

"Just admit it." Jiang Xiyu said calmly, "But not today."

"You care about me?" Christia narrowed her eyes: "He didn't even refuse..."

"I have to take care of it." Jiang Xiyu said seriously: "I'm not worried about Chen, I'm worried about you."

"You'll get into trouble." Jiang Xiyu reached out and tapped Christia's forehead: "Don't confuse games with reality, Your Majesty."

"You don't need to suck blood for a month now."

As he spoke, Jiang Xiyu took out his mobile phone, opened a folder and pointed the screen at her.

Cristiana looked at the data on the screen...data about herself.

Of course, these are not the strength assessment data as a demon king, but the various indexes when he is with Yu Chen.

For example, characteristics, interval duration, time limit and other data.

Looking at these data, Cristiana's expression froze, and then she heard Jiang Xiyu continue: "Based on the existing data, you'd better rest for three to five days, otherwise your brain will definitely have problems."

"We are all Chen's wings, so we can't really turn into a flannel ball, otherwise we will lose our original charm. What if Chen cheats?"

"I'll see, I'll see."

Christia was still there. Su Yuchen quickly broke away from Youzi, hugged her in his arms, and looked at Jiang Xiyu's phone screen.

Looking at the series of data, Su Yuchen's eyes lit up: "So professional?"

"Yeah." Jiang Xiyu raised her chin proudly: "For a happy life in the future, it is necessary to collect comprehensive data from everyone."

"Look at yours." Su Yuchen said quickly.

"I do not need."

"Why?" Su Yuchen asked subconsciously.

"Because I am a succubus." Jiang Xiyu said confidently: "I can't be broken, but Chen..."

"6!" Su Yuchen, who had nothing to say, uttered a number.

Cristiana came back to her senses and said quickly: "I am the Demon King, how could I collapse so easily?"

"Don't underestimate this kind of thing!" Jiang Xiyu said seriously after putting away her phone, "Because Chen is very strong and the feelings between them are very deep, so after the strong stimulation and the extreme contrast in their hearts, their thinking will become disordered."

"What you just showed is the sequelae of last night." Jiang Xiyu looked at her: "You can go look in the mirror now. Anyone can see what you want now, and they will definitely not associate it with the Queen of the Night."

Cristia opened her mouth, but had nothing to say... There was no way the succubus could deceive her about this.

"That's it." Jiang Xiyu emphasized again: "Of course, if you really want to, I won't stop you, but you have to be prepared to become addicted."

"Because of their thirst for blood, vampires are indeed like half succubus, but they are not true succubus after all. So once they collapse, the vampire's unique 'ghost transformation' may not be controlled."

"Are you willing to transform into a ghost in front of Chen and expose your ugly appearance?"

Cristiana quickly shook her head, then glanced at Su Yuchen: "I'm going to take a shower!"

Having said that, she quickly left the embrace that she was so obsessed with and walked quickly towards the bedroom.

"Hill, are you done washing? Never mind, let's wash together."

Hearing Christia's voice falling, Su Yuchen's eyes changed when he looked at Jiang Xiyu: "In this regard, you are more expert than Raorao."

"I am a succubus." Jiang Xiyu, whose face was a little pale, stretched out her hand and hugged the back of Su Yuchen's neck: "Do you want to see your data?"

Su Yuchen nodded, and then he and Jiang Xiyu started to look at it together: "Is it divided into normal and abnormal times?"

"Don't think I didn't notice. Chen secretly used magic to recover several times."

"Ahem." Su Yuchen looked away with a hint of guilt: "Then what can I do? None of them are fuel-efficient. What happened if I cheated?"

"I don't mean to look down on Chen." Jiang Xiyu explained quickly while rubbing Su Yuchen's cheek in a flattering manner: "Chen is the best, and his normal data is also very, very, very outstanding."

"How do you determine your standard of excellence?"

"Fight me, subdue me, feed me!" Jiang Xiyu looked at Su Yuchen seriously: "Under Chen's teachings, Xiyu has become the strongest succubus."

Su Yuchen was very pleased with the succubus's praise, and he almost looked down on her.

"Chen's various data are really very impressive, just as impressive as Chen's strength." Jiang Xiyu walked around the sofa and knelt on it like him, propping up the back of the sofa with his elbows and continued, "Record the data again next time when Chen is in an abnormal state throughout the whole process."

"I have a lot of magic power." Su Yuchen emphasized.

"I know." Jiang Xiyu blinked: "But we have to face seven people, so the main test is how much magic power you can consume to satisfy everyone."

"Then use this data as a benchmark and don't use magic. After all, Chen doesn't want to rely on magic assistance. Sage time is actually a kind of enjoyment, right?"

Su Yuchen nodded. It would have been really boring if he didn’t feel tired.

"I will also let the cat regulate your body so that Chen's normal data will be stronger."

"Can it be stronger?"

"Chen is only nineteen years old, and he still has a period of growth." Jiang Xiyu turned her head and looked at him: "Fully tap Chen's potential."

"Hmm...wait a minute." Su Yuchen seemed to remember something and turned his head to look at her who was so close to him. He also kissed her on the lips: "Will we all be together every time in the future?"

Jiang Xiyu shook her head: "Don't be like that!"

"That's fine." Su Yuchen breathed a sigh of relief.

"Chen is the head of the family, and matters like this must be decided by Chen!"

"Me?" Su Yuchen shook his head: "Sister Yu Shuang must have some ideas, but it's good, it can be arranged in a week... Uh, I don't have any days off?!"

Seeing Su Yuchen suddenly worried, Jiang Xiyu quickly comforted him: "Yu Shuang loves you so much, she must have made arrangements."

Su Yuchen nodded, and did not dwell on this matter any longer, but asked, "When will the experiment be conducted?"

"It's not an experiment." Jiang Xiyu corrected: "You have to do this with a pilgrimage mentality. This is the greatest thing in the world."

"Yeah, I understand!" Su Yuchen nodded quickly.

"Wait until I conquer my sister." Jiang Xiyu answered, then glanced at the phone, muttering to herself that it was a bit abnormal that her sister completely ignored her today.

"Okay." Su Yuchen took her mobile phone and looked through the data information of Sister Yu Shuang and others that she had not shown to Christia.

"How professional!" he couldn't help but sigh.

"Because I'm an academician succubus." Jiang Xiyu looked at Su Yuchen calmly: "It's all because of Chen's training."

Su Yuchen reached out and touched her head: "This is the result of Academician Jiang's own efforts."

Jiang Xiyu took the initiative to rub his palm: "Is Xiyu good?"

"sharp."

"Do you like Xiyu?"

"like."

"Xiyu also likes Chen the most."

Jiang Xiyu narrowed her cherry-pink eyes and changed the subject: "It's so uncomfortable to endure it for seven days."

"It will be over soon." Su Yuchen comforted: "By the way, Sister Yue will be here around this time too, right?"

"My sister was born one day later than me, and one day younger than me."

Hearing this, Su Yuchen felt inexplicably relieved. Seven minus two, he could suddenly relax a lot.

Thinking again that they occupy the time at the beginning, middle and end of the month respectively, I still have time to relax, if I let them all synchronize...

"No!" Jiang Xiyu said seriously: "I won't let what Chen wants happen."

"That's right." Su Yuchen nodded. During the menstrual period, you should rest when you need to, and you can cultivate relationships with other people, such as going on dates or going shopping. It's a good opportunity for both parties!

"Yeah." Jiang Xiyu nodded: "Chen, I'm going to school."

Su Yuchen has classes, but he is not in a hurry at all - when skipping classes becomes a habit and he has enough connections in school, he can do whatever he wants.

"Stay away from Chen for the next few days." Jiang Xiyu's spirit was a little sluggish: "I will be greedy for it."

"Just bear with it and it will pass." Su Yuchen touched her head: "After this is over, how about I accompany you for a day?"

"Handshake!" Jiang Xiyu immediately became energetic.

"Pink." Su Yuchen hooked her little finger: "But let's make it clear in advance, it also includes a date."

"Yeah." Jiang Xiyu nodded vigorously: "It's not impossible outside."

"..." Su Yuchen pinched her cheeks and said, "Be more restrained and go quickly."

"I'm leaving." Jiang Xiyu kissed him reluctantly, then stood up and walked out of the room.

Su Yuchen chuckled, sat back on the sofa and picked up his phone. Yuxi hadn't sent him a message yet.

Just when I was about to ask, Yae Mio sent me a message first.

"Master Chen, there are some clues."

Seeing the message sent by Yae Mio, Su Yuchen narrowed his eyes. He knew that Yae Mio was referring to the clues about the location of the 'Sky' intelligent system, because he had asked her to investigate secretly before.

After replying "See you at school" to Yae Mio, Su Yuchen stood up and walked towards the bedroom: "Sister, are you done washing?"

"I'm helping Hill wipe his body. What's wrong?"

"Master, you come in too..."

"Don't move!"

Listening to the noise inside, Su Yuchen laughed and said, "Let's go to school after we finish washing."

"You go wash up too."

"it is good……"

"How is it? Can you still tell that I look like a burnt...bah!"

"is that OK?"

Su Yuchen changed into his school uniform and walked out of the bedroom. He looked at Cristiana who was standing in front of him and couldn't wait to ask. After carefully looking at her for several times, he said, "I can still see that although you have put back your golden pupils, your eyes are really charming."

"Glasses can't cover it?" Christia asked somewhat frustratedly.

"Ah."

"Ah..." Christia slapped her cheeks. "Is the aftereffect of playing a little crazy last night so severe?!"

"Xiyu is an expert in this area." Su Yuchen walked up to her and gently held her in his arms: "But you have your second class in the morning, it's still early, don't worry."

"No, I need to change my class, and..." Cristiana quickly broke free from his embrace: "Stay a little further away, it feels weird when you touch me now."

As she spoke, she held her forehead with her hand: "It would have been fine if she hadn't said anything. Once she did, I really felt like something was wrong with my brain... My cheeks got hot again."

Su Yuchen chuckled and whispered, "After all, it is an extreme transformation from a high and mighty queen to a slave in shackles. Maybe I'll get used to it in the future."
