My senior sister is not a human being!

buzzing-

Su Yuchen took out his cell phone and Xia Yushuang sent him a message saying that he could leave. Su Yuchen replied "Got it" and put the white cat on the book.

"Meow?" The white cat woke up and quickly got up and called out.

Su Yuchen rubbed the little guy's head and said, "I have to go home. You just wait for your master here obediently."

The white cat purred but did not try to keep him. It licked his palm with its tender pink tongue, then sat obediently on the book and called out to him twice.

"Bye-Bye."

Su Yuchen turned and left. The white cat jumped onto the windowsill with a "whoosh". After waiting for a while, it saw Su Yuchen's figure, put its two little paws on the window glass, and its big furry tail wagged happily.

It didn't put down its two little paws until it could no longer see Su Yuchen.

"You told me before that you studied medicine to help someone. Is that him?"

Mu Lingyan appeared like a ghost between two rows of bookshelves, looked at the white cat on the windowsill and asked softly.

The pure white magic light flickered, and the white cat on the windowsill turned into Bai Raorao, who was standing on the floor with a fierce look. Her azure blue eyes had calmed down a lot. She glanced at Mu Lingyan and whispered, "I won't tell you."

"I understand." Mu Lingyan smiled slightly and walked towards her. Bai Raorao took two steps back vigilantly, her pure white hair a little blown out.

"Since you like him, why don't you dare tell you that he is a cat?" Mu Lingyan asked curiously.

Bai Raorao didn't say anything, so Mu Lingyan started talking to herself: "Whether it's Jiang Shengyue, Xia Yushuang, or Sylvia, none of them dare to say it... What makes you afraid to say it?"

"Because he's a human?"

"Is that why you don't dare to say it? Is 'liking' such a strange feeling?"

"You don't understand." Bai Raorao said in a low voice.

"Don't understand?" Mu Lingyan tilted her head: "I just don't want to understand. For me, these feelings are unnecessary."

"Then why are you asking so many questions?" Bai Raorao asked fiercely.

"It's because of you that I asked so many questions." Mu Lingyan stretched out his hand and tried to touch her head, but Bai Raorao dodged it nimbly.

Mu Lingyan smiled and said, "Your medical skills are outstanding, so I care about you."

"No need!" Bai Raorao snorted, puffing her cheeks.

"How about I use him to threaten you?" Seeing the fierce light in Bai Raorao's eyes, Mu Lingyan shrugged his shoulders: "See, the feeling of 'liking' is just a burden."

"These feelings can only become a bondage and make you weak."

Bai Raorao didn't say anything, but the magic power in her body gradually became violent.

"If you are in heat, you'd better be quiet, so as not to backfire... Don't worry, I won't do anything to him."

Mu Lingyan turned around and said, "Your 'master' might be stronger than you expected."

"It has nothing to do with how powerful he is." Bai Raorao said seriously: "I won't let him be bullied!"

"I've finally discovered that your love for him is a little... morbid."

"Raise him as a child? Aren't you afraid he'll become a waste?"

Mu Lingyan said without comment and waved her hand: "Let's talk about this for today. See you tomorrow."

Bai Raorao slowly calmed down and whispered softly -

"What does it matter if I raise a waste?"

Chapter 197 "Yu Chen looks so gentle now"

Office of the Dean of Students.

Mu Lingyan took off her school uniform jacket and hung it on the hanger, then walked to the window and looked at the students coming and going under the night lights. As the student union president of Sky University, she had a separate dormitory, but most of the time she did not go back to the dormitory, but rested in the office.

Although there was no bed, an office chair was enough, and she didn't care too much about it.

He closed the curtains, turned around and sat down on the office chair, opened the screen of the space window, leaned back in silence for a while and asked, "Su Yuchen."

The screen soon made a different sound than before, causing her to sit up straighter.

"The system is being upgraded, please do not disturb."

"Upgrade?" Mu Lingyan glanced at the screen with a little surprise. Not to mention that she had taken office as the student union president in her junior year, the last upgrade of the 'Sky' intelligent system was seventeen years ago.

Although the world is progressing at a fast pace, it is only a drizzle compared to the 'sky'. The current 'sky' is too good. At least, humans today cannot recreate an identical 'sky'.

Although she reminded him to "do not disturb", Mu Lingyan still asked, "How long will it take?"

While speaking, her hands were already on the keyboard. She didn't mind if Sky didn't answer and forced her way through several of its firewalls to interfere.

The student council president of Sky University has the authority to communicate with 'Sky', but it is just communication. Whether 'Sky' will pay attention to you is another matter.

However, after Mu Lingyan took office as the student union president, he took advantage of the time when the main system of the "Sky" intelligent system was dormant, launched a sneak attack and "forced" to reach a cooperation agreement with "Sky", allowing "Sky" to communicate with him at any time and putting "Sky" in an equal dialogue position with him.

"uncertain."

Sky's answer made Mu Lingyan frown: "Are you sure it's an upgrade, not a problem with the main system?"

The 'Sky' intelligent system is, after all, an intelligent system, a super system that exists on electricity and the Internet. If the whole world loses power, it will not be able to operate, but obviously, this is impossible to do.

Putting aside whether countries are willing to bear the losses after the power outage, the power of "Sky" will actively counterattack. Forcibly starting the power supply and finding a power source that has not been cut off are its means.

So now Mu Lingyan wondered whether some countries had joined forces to attack the firewall of "Sky" or destroy the main circuit connected to the main system.

"No."

Hearing Sky's denial, Mu Lingyan leaned back in her chair again: "You are so useless."

First, she couldn't give her feedback on Su Yuchen's situation. Now she asked Su Yuchen again, and the system was upgraded inexplicably again. What happened? Was it conflicting with the name 'Su Yuchen'?

Mu Lingyan thought for a moment and spoke again: "Bai Raorao."

'Sky' fell silent. Mu Lingyan placed her hands on the keyboard, still without any response, so she directly entered the main system of the 'Sky' intelligent system.

The screen of the space window suddenly changed, and a ball of light fog appeared on the screen in the darkness. Mu Lingyan knew that this was the brain of the "sky". Although it only existed on the screen, it encompassed everything.

So far, except for 'Su Yuchen', there is no question that 'Sky' cannot answer... Su Yuchen's question can also be answered, but compared with the answers to previous questions, it is too brief and contains almost no useful information.

Mu Lingyan stared at the ball of light fog and after a careful inspection, she found that there was no sign of invasion. However, compared to the light fog that was as scorching as the sun before, the light fog at this time was more like a hibernation period, and it was terrifyingly quiet.

"If you don't speak, I will attack your main system."

The sky remained firm and motionless.

Of course, Mu Lingyan would not really attack. After all, there were so many things she could do relying on the intelligence from "Sky".

After exiting the main system of Sky, Mu Lingyan retrieved Su Yuchen's student file and muttered to herself as she looked at the limited information on it: "Is Su Yuchen... related to Su Yuxi of the Xuanqing Empire?"

Since he couldn't rely on "Sky" and he was particularly free today, Mu Lingyan began to investigate personally.

As someone who could "threaten" the Sky Intelligence System, her level of network technology in the field of magic engineering was naturally beyond elaboration, and she directly invaded the core database of Chang'an State.

"Hmm?" Mu Lingyan raised her eyebrows, a little surprised: "Such a strong defense system?"

Then, he had the urge to destroy this defense system to pieces, but he suppressed the urge and began to look for a way to sneak in quietly.

"It's still a little weaker than the sky."

Thinking of this, Mu Lingyan operated for fifteen minutes and entered the core database of Chang'an Kingdom.

She didn't even take a look at the high-level information, economic data, and military strength of Chang'an State. She just kept looking for clues about "Su Yuchen".

"found it."

Mu Lingyan narrowed her purple eyes slightly: "The relationship between me and Su Yuxi is...superior and subordinate?"

"A member of the [Han Chan] Special Operations Agency, responsible for gathering intelligence on the [Seven Corners Alliance] in the north of Chang'an, codenamed 'Weakest'?"

Mu Lingyan blinked and looked up Su Yuchen's battle record as a member of [Han Chan]. Four words were written in capital letters on the screen: None of them were successful.

The evaluation was indeed in line with the code name of "weakest", but Mu Lingyan was a little confused. What was the point of keeping such a special operations personnel? Wasn't it a waste of resources?

Mu Lingyan continued to flip through the pages while thinking about it, and saw a small line of words added by someone unknown: (Very close relationship with Her Royal Highness the Princess).

Mu Lingyan was stunned for a moment, then her expression became a little strange: "Could it be that he is Su Yuxi's male lover?"

She knew that some nobles had unknown hobbies, and as a princess of the Xuanqing Empire, Su Yuxi, while maintaining her wisdom and intelligence on the surface, it was understandable that she had some special hobbies in secret.

'If that's the case, it would explain why he wasn't fired.'

Not finding any more useful information, Mu Lingyan took her hands off the keyboard and guessed: "He is useless, but he is Su Yuxi's male lover, so the top management of [Han Chan] couldn't stand it and assigned him to Sky University..."

"No, no."

Mu Lingyan frowned. "If I'm so useless, how can I possibly attract the favor of Christia and the others? They are not just random beauties on the street. If I use their intelligence to do other things, I should be able to do it easily."

"and……"

Mu Lingyan thought of the human who had fought with her that night. Now she has placed the greatest suspicion on Su Yuchen, so the information she sees now is mixed with Su Yuchen... It's too conflicting!

"Is this information false, or is Su Yuchen not that human at all, and I am just overthinking it?"

Mu Lingyan put her hands back on the keyboard and began a new round of careful intelligence collection. She started from the entire Chang'an Kingdom database, collected information about Su Yuchen, and then summarized it again. The result was...

Still the 'weakest' one who has never succeeded in any mission.

"It's impossible that there are still things hidden in the database of Chang'an State. So Su Yuchen is that person?"

Mu Lingyan frowned. Whenever she thought of this result, she felt a strong sense of disconnection, as if there was something strange and indescribable.

"He stood with Christia on the night of 'Taboo', so it makes sense that he was arranged by Christia to rescue Phyllis afterwards... The one who fought with me that night was indeed a human, not a vampire."

"But if Su Yuchen is so powerful, why hasn't he completed any of the missions?"

"I already have the population data of Sky City. Except for Cristia and the others who concealed their powerful identities and backgrounds, the others who concealed their identities are just 'dogs' sent by various countries."

"The night that human left, due to the interference of the 'taboo', all surveillance was in a state of failure and we were unable to track his whereabouts. Could he have left the Sky City?"

"Is Su Yuchen really not that powerful human?"

Coming to this conclusion once again, Mu Lingyan leaned back in her chair and rubbed her brows. The conclusion she had collected herself made it impossible for her to believe it 100%.

She always felt that something was a little strange—her sixth sense as a strong person told her so.

"The biggest suspect is Su Yuchen, who is close to Cristiana and the others."

Mu Lingyan murmured to herself, anyone who dared to dump so many famous seniors at once must be confident in some way.

And this self-confidence does not come from the so-called "living a good life", because Christia and the others are not so vulgar.

"After checking for a long time, I still have to judge by contact."

After exiting the core database of Chang'an State, Mu Lingyan sighed lightly, picked up the pen on the table and wrote the three words "Su Yuchen" on the white paper. For the first time in history, an uncertain factor appeared.

"You have to join the student union even if you don't want to."

Mu Lingyan leaned back in her chair, closed her eyes, and silently thought about what method she could use to make him reveal any possible flaws.

At this moment, she inadvertently noticed that a message was sent out from the main system of the 'Sky' intelligent system: Su Yuxi will arrive at the Sky City International Airport at 11:9 pm on November 14, under the alias 'Xichen'.

……

Ever since the failure of the summoning of the 'Lost Array' caused a series of turmoil within the Amaterasu Kingdom, the high-spirited Yae Shinshin has become much more haggard.

Fifty years of hard work by two generations, fifty years of secretly hunting down the King Blood Monster, fifty years of arresting relevant researchers from various countries, fifty years of investing trillions of dollars...all lost in one night without even having anything left!

The Emperor's illness is not a big deal. The main thing is that the 'Lost Array' was still cooperating with the elves, other countries and forces. Now that everything has failed, they are all looking for trouble with the Amaterasu Kingdom!

Although he was in the Castle in the Sky, Yaezaki had to deal with too many things and felt exhausted these days: students from various countries at the Sky University were backed by national strength, but after the failure of the 'Lost Array', some students who knew about this had come to him more than once to ask for an explanation. Yaezaki wanted to fight back directly, but... Amaterasu owed too much and he lacked the confidence!

Whenever he thought of all these troubles, Yae Shinshin couldn't help but kick a stool to pieces and curse, "Damn vampires, damn Beth clan, damn Queen of Eternal Night"!

"You guys obviously want to use the Array of Lost, but what's the point of destroying it all? Isn't it nice to have a win-win cooperation? Baka! Xinei! Xinei!"

Looking at Yae Shinkami venting his anger in the dormitory, the three roommates from Amaterasu Kyoei Koku didn't dare to breathe, for fear of being used as a punching bag - the wounds on their bodies from being beaten by him to vent his anger had not yet healed.

After venting his anger, Yae Shinshin pulled his hair, his eyes reddened: "No, we must find a way to divert their attention and make them stop pursuing this matter so frequently."

ding dong~

As soon as he finished speaking, the phone on the desk vibrated. Yae Shinshin picked it up and took a look. He thought it was a message from Yae Mio and was about to vent his emotions, but the next second he was stunned: "Text message?"

and--

Su Yuxi will arrive at Sky City International Airport at 11:9 on November 14th, using the alias 'Xichen'.
