"Sir Amano, my Master is currently sleeping, please refrain from walking around the lab without supervision, please leave now or I will have to act upon my own action."

W41-FU threatened Yukio by controlling many combatant androids inside the lab. The androids' eyes were glowing red and they started moving towards Yukio. There were about thirty combatant androids who were ready with their weapons behind W41-FU. Yukio hesitated when he saw this small army of high tech androids pointing their weapons at him, although his biochip allowed him to defeat one or two of them, but it was impossible against thirty androids.

Yukio raised his hands, making a tired expression and said, "Fine then, I will leave now."

"Wise choice, sir," W41-FU put all the android back to stand-by position and then said, "The transporter has been prepared, have a good day, sir."

Yukio used the transporter and returned back to his rented room. 

Yunyu felt that something was fishy the whole time, from the suspicious assault last night, the exact same core machine in the combatant androids in this lab, and W41-FU's hostility. Yunyu was sure that the android who attacked him came from here.

But Sakuma had been sick the whole time, of course he had no time to attack him.

[Maybe, it's W41-FU? In the original story, W41-FU's self-developing system turned hostile after Sakuma's death and killed everyone, right? So, Sakuma might not know anything about this and W41-Fu acted on its own.]

[Pupa: That is possible. But don't take Sakuma out of the picture.]

[What do you mean? He is sick the whole time.]

[Pupa: He never leaves his fully sterilized lab, let alone interacting with someone who has a flu. How could he get the virus? Influenza or Flu virus can only be transmitted by someone who has it.]

Yunyu froze as he realized that Pupa made sense in this situation. How could Sakuma contact a common flu, when he hadn't met anyone.

Yunyu gathered the clues and concluded something in his head, but it was ridiculous, so ridiculous that he didn't think it was possible. He asked the system about medication in this world.

[System, if you got sick with common flu in 2121, can't you just… use injection or advanced medicine to recover immediately?]

[Pupa: Yes, something like flu, fatigue, sore throat and many other common illnesses are negligible in this era. When drugstore medicine in this world can cure it in less than 24 hours. There is also an instant injection that can cure you in less than three hours.]

[But the android maid said that Sakuma has been catching the flu for three days already. It just doesn't add up. In my wildest imagination, I think Sakuma was the one who attacked me and Mamoru last night, but he underestimated my skill and I was able to beat his android. Knowing that he might be discovered, he activated that android's self-destruction command, then he used one of his technology to infect himself with the flu virus as an alibi. Of course, I won't suspect someone who has been very sick for three days straight.]

[But that's just my wildest prediction, because if Sakuma actually did the exact same thing as my wild prediction, then he is nowhere a good man. He might be more dangerous than Bi He.]

[Pupa: Are you really my host, Bai Yunyu?]

[What? What do you mean?]

[Pupa: Because you are making too much sense, it scares me. I'm used to my butt brain, spicy chicken host. Please come back.]

[… I spent my entire brain power to think about that possibility, please show me appreciation or I shall report this as verbal abuse!]

[Pupa: And you will call it dirty talk if Han Ye is the one who said it.]

[W—Well, he is a kind man, of course he only uses that kind of words to make things more exciting! Hehe~]

[Pupa: You haven't even talked to him once.]

[I will! I will confess too!]

[Pupa: Hmm… based on the data about your life, you remembered all the lines of female leads in all Han Ye's movies, and you tried to replace the female leads' dialogue when they were talking to Han Ye… why does it sound depressing?]

[Hey! That's my secret! What if my fans know my dirty secret!?]

Yunyu got a message from Mamoru, telling him to stay safe until he could track the culprit behind their attack. Mamoru seemed to be very eager to catch the culprit, and it only made Yunyu even more nervous. 

If Sakuma was the culprit, then Mamoru would be guaranteed death once he found out. Sakuma was far more dangerous than he looked. Mamoru was a kind hearted, righteous, young man, Yunyu didn't want to hurt innocent bystanders, let alone a good one like Mamoru.

Thus, his highest priority now was to protect Mamoru if his prediction about Sakuma was correct. 

Yukio called Mamoru;

'A—Amano-San! Good afternoon!' Mamoru greeted excitedly after he picked up the call. He never thought that Amano-San would take the initiative to call him first.

'Mamoru, I want to tell you something. Let's meet up tonight. I will see you in the café near our old police station.'

'Yes, Amano-San! I will come on time!'

Yukio closed the call and he stared around his room. He started searching for something like a recording or tapping device that might be used by Sakuma to spy on him.

[Is it possible that he modified my body and put a recording directly inside my body?! That's freaky!]

[Pupa: It's not entirely impossible.]

[Holy shi—]

Meanwhile, Sakuma was watching Amano-San who was busy searching for something in his room. He scoffed mockingly as his heart grew colder. He had fully recovered from his 'flu' thanks to an advanced medicine. 

His eyes were unblinking as he stared at the monitor, which showed everything through Amano-San's eyes. What Amano-San saw, he also saw the same thing. It was really fascinating, yet heartbreaking at the same time. 

Because Sakuma knew that Amano-San had seen through his plan, perhaps he had underestimated Amano-San, he thought it would take longer than just a day for Amano-San to blow his foil. 

Sakuma laughed mirthlessly, he laughed at himself for thinking that Amano-San would be tricked easily. If convincing Amano-San needed some force, then so be it. If he wanted to meet that Mamoru guy, then he would prepare for the worst date he could ever imagine. 

"You can't just run away after you give me that kind of warmth, I will not let go."

Sakuma laughed again, but it was so bitter, that his AI couldn't help but notice it, "Master, you sound very sad. Does Yukio Amano make you sad? What do you want me to do?" 

Sakuma typed something in his command and then W41-FU confirmed the command from its master, "Operation Perfect Android: Control has been activated, waiting for Master's input in six hours."
