My senior sister is not a human being!

"Okay, I'm going to go prepare dinner, you can play by yourself for a while."

Xi'er opened his mouth and looked eagerly at Xia Yushuang's figure walking into the kitchen. He hurried to the sofa and picked up his phone. While opening the chat interface, he muttered softly: "Master is so good, it must be my sister's fault, but what mistake did my sister make?"

After quickly typing and preparing to send it out, Hill's fingers paused, and his bloodshot eyes became dazed again. Even if he sent the message, would his sister reply to him?

She will definitely say that she is a child and doesn’t understand anything, so don’t ask, right?

Absolutely!

Thinking of this, Hill put away his phone, looked up in the direction of the bedroom, hesitated for a moment, and walked over quietly. Since there was a problem in the relationship between the master and his sister, as the master's student and the sister, he should help.

First of all, I need to figure out the reason for the conflict... If Master still likes me, he might still tell me about this...

"Master, are you sleeping?"

Xier walked to the bedroom door and carefully poked his head in. He looked at Su Yuchen, who had changed into pajamas and was lying on the bed with a cat on his chest. "Xier, can I come in?"

Su Yuchen sat up and crossed his legs. He held Shao Shao in his arms and smiled at Xi Er while petting the cat: "Of course."

"Then, then Hill comes in."

The little Lolita in a black Gothic skirt walked in cautiously with her little legs bare. When she reached the bed, she hesitated for a moment before putting her little hands on the bed. She knelt on the floor with her short legs and put her chin on the bed. She looked up at Su Yuchen with her eyes raised. Her expression and posture looked very cute.

"The little girl will definitely grow up to be as good as the queen."

This thought flashed through Su Yuchen's mind, and he couldn't help but reach out and rub her little head: "What's wrong?"

"Hee~" Hill narrowed his eyes and enjoyed the master's pat on the head very much. The master still liked Hill.

"Master, my sister..."

"Let's not talk about this for now." Su Yuchen looked at her: "Is there anything else?"

Seeing that Su Yuchen didn't want to talk to her, Xi'er knew better than to ask any more questions. She tilted her head and put her tender little face against his big hand. She bit her lip and whispered, "Master, don't be angry. Even if my sister doesn't want you anymore, Xi'er still wants you... Xi'er can take care of you for the rest of your life... I'm sure I can do better than my sister."

Su Yuchen smiled but didn't say anything. Xi Er pouted a little unhappily. Humph, her status in the master's mind was still not as high as her sister's.

Is it because I am a child?

Could you please tell me if sisters Yu Shuang and Xi Yu would be better?

"Master, do you hate vampires?"

Su Yuchen pinched her cheeks, bent down, picked her up and put her on his lap. Shaoshao meowed softly, then lazily lay on his owner's shoulder and licked his cheek affectionately.

"Hill is so cute, I won't hate you."

"Hee~ Master is so nice." Xier shook his short legs: "Then sister... No, it's okay."

Subconsciously wanting to speak up for her sister, Xi'er quickly closed her mouth, and quickly kissed Su Yuchen on the other side of his face and asked in a low voice, "Then will Master take Xi'er to the amusement park tomorrow?"

"Yes, of course." Su Yuchen said softly, "I promised you, so of course I will take you there, but you have to agree to one condition."

"What are the conditions?"

"You can't tell your sister." Su Yuchen looked at Xi'er's bloodshot eyes: "Do you understand?"

Xier hesitated for a moment and then nodded: "Xieer knows, and will definitely not tell my sister... Then will only Master and Xier go together tomorrow?"

"Yeah." Su Yuchen nodded. Hill seemed to be unaware of his "unfortunate" incident, but he certainly would not go alone. Sister Yu Shuang and Raorao would definitely go with him... otherwise, they wouldn't be able to enjoy any of the attractions.

"Yeah~ Master is so nice!" Hill cheered immediately, and stood on Su Yuchen's legs with his two short legs. He put his arms around Su Yuchen's neck, and kissed him on the face a few more times.

"Let's go to the living room and get ready for dinner."

"Hmm~"

Hill was happily held in Su Yuchen's arms, his bloodshot eyes staring at Su Yuchen's profile. Well, if sister doesn't want a master anymore, I will want one myself, huh!

……

Under the cover of night, a teahouse somewhere in Sky University was still crowded with roommates and couples chatting and laughing here. The noise only died down a little when a few tall and strong pure-blooded werewolves walked in.

It is indeed a rare thing for a werewolf to come to the teahouse.

Kane and Pinto, who had passed the entrance exam and put on their school uniforms, walked directly into a private room on the second floor of the teahouse under the guidance of Derek. Looking at Yae Mio and Kujo Mai sitting in the main seats, Kane immediately showed a bright smile on his face.

"I heard that the Amaterasu tea ceremony is very popular. We are lucky to have the opportunity to experience the tea art of Prince Amaterasu."

Kujo Mai, who was sitting next to Yae Mio, frowned slightly. Who did this werewolf learn to be so literary... He didn't look like a Western werewolf at all.

"You think too much." Yae Mio glanced at Kane calmly and said, "There is only one person in the world who is worthy of me making tea, and it's not you."

"Oh, who is it?"

"It has nothing to do with you." Yae Mio picked up the teacup and took a sip: "The information you want has already been revealed."

"It just so happens that I have some clues here as well." Kane sat on the tatami and glanced at Derek. Derek immediately said, "The information I received is that the teacher of the Magic Engineering Department, Tia Yufei, has a sister named Hill Yufei. Her appearance fits the characteristics of a vampire, so the chance that Tia Yufei is that vampire is very high."

Hearing this, Yae Mio raised a sarcastic smile, and Kujo Mai also responded with a playful look.

Kane frowned: "Isn't that right?"

Jiujiao Wu said calmly: "You are only half right."

"What do you mean?"

Jiujiao Wu picked up a document from the side and handed it over: "According to the intelligence we have collected from various sources, Xier Yufei appeared after the day when the 'Lost Array' plan failed. In other words, she is indeed very likely the little princess of the Night Empire that you told me about."

Kane took the document and took a look at it. He immediately determined that this was the final truth formed by the convergence of various intelligence clues. He raised his hand and handed the document to Pinto: "Look, this is what we call professionalism."

Pinto watched without saying a word. Jiujo Wu continued, "Teacher Tia was indeed present at the time, but there was another person present at the same time... Su Yuchen!"

"Su Yuchen." Kane narrowed his eyes and said, "Why, do you suspect he is the vampire disguised as a human?"

"Yes." Kujou nodded slightly, and Derek immediately retorted: "Did you know that the vampire we are looking for is not a male?"

"I know." Jiujo Wu said calmly, "If Xier Yufei is a vampire princess, then according to historical records, the person you are looking for is most likely the Queen of the Night, isn't she?"

"How do you know?"

"Don't talk!" Kane scolded, looking at Kujo Mai with a smile: "Humans are indeed smarter than most monsters... Keep talking."

"Hill Yufei has been living in Su Yuchen's house." Jiujiao Wu said calmly: "And the Queen of the Night disguised herself as a human and hid in the Sky City, so why is it impossible for her to disguise herself as a man?"

Kane thought for a moment, "That makes sense. Anything else?"

"Anything else?" Yae Mio said slowly, "This is all we can infer from the known information. If you insist on doubting Teacher Tia, you are just being stupid."

Pinto frowned: "Tia Yufei was also in the central area of ​​the 'Lost Array' at that time, and there were other blood princes present at the time..."

"But the blood prince didn't do anything, right?" Yae Mio said calmly, "Otherwise, the Sky City would have been destroyed a lot by now, right?"

"Besides..." Yae Mio smiled slightly: "Teacher Tia likes Su Yuchen. Do you think the Queen of the Night would like a human?"

The answer to this question is obvious. In the eyes of werewolves, how could the vampires, who claim to be the most noble, look down on humans who are at the bottom of the monster world?

"It is impossible for vampires to like humans. They only treat humans as blood banks. Teacher Tia has never shown any signs of sucking blood... Even if she is a vampire disguised as a human, it must be a smokescreen released by the Queen of the Night."

"So who is the Su Yuchen she likes?" Yae Mio looked at Kane who was in deep thought: "Why is Hill so close to him? The answer is obvious, isn't it?"

Pinto opened his mouth. “Will the Queen of the Night disguise herself as a human male?”

"For the sake of the Lost Array, to awaken Hill Yufei, it's just a matter of a woman disguising herself as a man. What's not worth it?"

Kane nodded: "Indeed."

Yae Mio nodded, stretched out her hand to crush the tea set into powder, and stood up: "We have done what we should do, remember what you promised after you win."

"Wu, let's go."

Kujo Mai quickly followed Yae Mio's steps and left the private room.

Kane immediately stood up and said, "Get ready to attack Su Yuchen."

"Lord Kane, do you believe it?" Pinto asked quickly.

"You still don't believe it?" Kane glanced at him. "Su Yuchen is very hostile to werewolves, otherwise he wouldn't have killed William the first time they met. Moreover, he can easily kill the final form of a werewolf... Is this something a human can do?"

Pinto hesitated for a moment and then shook his head: "Although I also suspect that he is not human, but just disguised as a man... and he is only a freshman, the time doesn't match."

"If she re-enrolls with a new look, it would be reasonable for her to stay in Sky City and not be expelled, right?" Kane said calmly, "Could it be possible that the Queen of the Night is still studying for a master's degree? There is no student union in the graduate school of Sky University."

"But why doesn't she work for a government department? She could collect more intelligence that way, right?"

"Do you think the guy from Sky City will let her into the government of a neutral city?"

"Indeed not." Pinto shook his head.

"So get ready." Kane took a step forward: "Tomorrow is Saturday, Su Yuchen probably won't come to school."

"If we take action in Sky City, the authorities won't say anything."

Pinto, all doubts dispelled, nodded: "I'll arrange it right away."

……

Chapter 422: Master wants Hill to wear black tights or white tights?

"What are you looking at?"

After dinner, Xia Yushuang washed the dishes and walked into the living room, wiping her hands: "Who are you chatting with?"

"Yae Mio." Su Yuchen handed over the phone without hiding anything: "After laying the groundwork for so long, the werewolf took the bait as expected."

Xia Yushuang glanced at him and then looked away. She sat next to him and said with a smile, "With an intelligence advantage, even the smartest people can't help but fall into this trap."

Su Yuchen nodded: "Even if the werewolves have concerns and suspect something is wrong, they will not be able to help but give it a try... After all, the Star Tribe is too eager to find Christia's whereabouts."

After saying that, Su Yuchen lowered his head to look at Shao Shao who had fallen asleep on his legs: "Where's Xi'er?"

"In the second bedroom." Xia Yushuang leaned on his shoulder: "She is excitedly changing clothes."

"Does she have any other clothes besides those Gothic dresses?"

"do not know……"

As soon as Xia Yushuang finished speaking, Xi'er ran out excitedly amid a burst of hurried footsteps: "Master, Master, what do you think of Xi'er wearing this skirt?"

Su Yuchen only took a glance and quickly looked away. Xia Yushuang stood up helplessly and picked up Xi'er: "Can't you put on some clothes before coming out? How will it look like to come out naked holding onto your skirt?"

"It doesn't matter if Master sees it."

Xia Yushuang immediately gave her a slap: "Go, go inside and get dressed."

Su Yuchen breathed a sigh of relief and gently stroked the soft white fur of Shaoshao curled on his legs. He reached out for his phone, sent a good night message to Yae Mio, then picked up Shaoshao and walked to the balcony to sit on the hanging chair.

Just as I was thinking about tomorrow's plan, Hill ran out excitedly again. She was wearing a Gothic black dress with white lace edges. It had rose and thorn totems based on the traditional iris, making her look like a little devil.

"Master, does Hill look good?"

Hill turned around and looked at Su Yuchen hopefully: "This is Hill's favorite dress."

"It looks good." Su Yuchen smiled. Although this overly dark style of skirt made Hill look rebellious, it looked good... and it was indeed suitable for Hill as a vampire.

"Then Hill will wear this dress tomorrow." Hill blinked her watery eyes, moved closer to Su Yuchen, put her two small hands on his bed, and raised her eyes: "Then Master... do you want Hill to wear black tights or white tights?"

Looking at the little girl's shy expression, Su Yuchen reached out and rubbed her golden hair: "Who told you to ask that? Sister Yu Shuang?"

"Hill asked it himself." Hill blinked: "Which one does the master like?"

Su Yuchen glanced at the black dress she was wearing: "White, right?"

"Okay~" Hill's face was filled with a bright smile: "Hill will wear white tights."

After saying that, he ran back to the second bedroom, and ran out again not long after.

Not only were there a few pairs of pure white pantyhose or white silk stockings in her hands, she was also holding a bag of blood and sucking on it.

"Master, which one should I wear?" Hill stuffed a few white socks into Su Yuchen's hands, holding Christia's blood bag in both hands and sucking it mouthful by mouthful.

Looking at Xi Er who did not hide herself at all, Su Yuchen picked out the thickest one and handed it to her: "Wear more, kid."

"Hmph~ Hill is not afraid of the cold!" Hill disobeyed and picked up a piece of white silk: "Hill wants to wear this."

"As long as you're happy." Su Yuchen said perfunctorily. If he insisted on asking Hill to wear something thicker, it would seem that he was afraid that she would wear white stockings, which would make him look like a pervert.

"If you feel cold then, don't blame me for not reminding you."

"Master, you don't know how to appreciate." Hill took a few white socks and turned to walk towards the second bedroom: "Hill will be the most beautiful tomorrow!"

Su Yuchen helplessly held the cat and stood up, pulling up the curtains, looking at Xia Yushuang who was sitting on the sofa peeling an apple: "Did she see something she shouldn't have seen?"

"Who knows?" Xia Yushuang handed over the apple: "After eating the apple, go take a shower and get ready for bed. I'll go and coax Hill to sleep first, otherwise she'll keep wanting to run to the bedroom."
