In one word, Dr. Oya Yayan's house is dirty, messy and poor.

Not only had the room not been cleaned in a long time, there was also a foul smell in the air, and on the floor one could see traces of mucus that looked like something had slid past and left behind. Seeing this, Saya was visibly embarrassed.

"Dad used to be in charge of cleaning..."

“…”

Fang Zheng didn't say anything, but walked to the bathroom, opened the door, and saw the bathtub full of bones of small animals such as cats, dogs, and birds...

"My father wouldn't let me throw it away, saying it would be bad if we were discovered..."

At this moment, Saya was like a college student who was caught by the dormitory supervisor during the dormitory inspection. She timidly defended herself, but... of course she had no confidence.

With all this garbage on the floor, any dormitory would be doomed.

Fang Zheng snapped his fingers, and soon, flames appeared out of nowhere, burning all the bones in the bathtub to ashes. This dispersed the source of the stench of decay a little. He stared at the burning corpse and then asked.

"What do you usually eat?"

"Well... Dad would buy me some food, such as chicks and ducks, and I would occasionally go catch some cats and dogs nearby..."

Having said that, Saya timidly looked back at the Husky that was staring at her.

"Can't you eat human food?"

"Human food...is not tasty."

"Then I'll check you out when I get back."

Fang Zheng was not particularly surprised by Saya's answer. Thinking carefully, since the doctor had summoned Saya, he would definitely not let her run around. However, if it came to feeding her, with Dr. Oya Masahiko's income, it would not be a problem to feed Saya like a kitten or a puppy.

But in this state, Saya actually wants to eat living flesh, which means there must be something special.

Otherwise, let alone anything else, it wouldn’t be very easy for you to buy a dead pig or cow or something like that, right?

Like the monster Fang Zheng encountered in Dunwich before, the Wilbur family bought cattle and sheep from all over the place to feed the monster. Of course, if the monster was extremely hungry, it would eat people.

Maybe it's because there are no pastures here?

"Okay, go check around and see if there are any clues. You can go too."

Fang Zheng gestured to Nymph and Asakura Ryoko, and also said something to Saya, and then the three girls dispersed and searched for clues in various parts of the house. However, according to Saya, there were no clues in the house. After all, she had lived here before. If she could get some clues from it, Saya would not need to risk going to the hospital to wait.

Having no satellite network is a hassle.

While going to the bookshelf to flip through those boring scientific research books and periodicals, Fang Zheng shook his head and sighed. If this happened in modern times, the little angel would probably be able to find out the other person's entire family history. Unfortunately, in this era, there is no Internet, not even computers, so there is no point in finding out.

The first electronic computer in modern human history was not developed until 1946, which is still several years away.

And that was a lot of stuff that would fill up an entire building. I guess the little angel wouldn't even want to touch this kind of stuff.

Although it's useless even if you touch it.

In fact, in the end, everyone did not gain much, except for a few land deeds... Well, it was a good gain to know that Professor Oya Yayan had several other residences besides here, but that was all.

In the next few days, Fang Zheng worked during the day and treated Niosaka Yuki. Of course, considering Saya's performance in the game, Fang Zheng also asked Saya to investigate her while she was unconscious. Saya also said that she had the ability to complete this transformation, but she had to find someone to do an experiment first... and it might not be successful.

In this regard, Fang Zheng had no moral obsession. He simply went to the prison and caught a criminal on death row. Then, he watched Saya happily playing with the man's brain, and easily completed the entire research work. It had to be admitted that these followers were indeed several levels higher than humans in terms of IQ. Saya only read the human medical monograph of this era, and then dissected a person's brain alive, but his understanding of human tissue had surpassed the top brain experts in the 21st century.

If I think about it this way, if the black goat kids all develop their intelligence, they might be more difficult to deal with. It would be easier to deal with them if they simply multiply and reproduce based on their instinct!

So Fang Zheng struck while the iron was hot and asked Saya to transform Niosaka Yuki's brain and change his worldview back to that of a normal person. According to Saya...

"The pineal gland in this human's brain has been damaged and swollen to a certain extent, probably due to an external impact, which is why his level of perception has been heightened."

"Pineal gland?"

Fang Zheng was a little surprised to hear Saya's answer. He knew that in the game, Ikuki Niosaka became like this because of a car accident. And since Saya was able to use physical means to correct Ikuki Niosaka's cognition in the game, it meant that there must be something wrong with his brain. However, Fang Zheng and Nymph were not brain science experts, so they didn't know the reason.

After hearing what Saya said, Fang Zheng realized that it was the pineal gland...

"This is really unexpected..."

After listening to Saya's report, Fang Zheng thought for a moment.

"So, by adjusting the pineal gland, you can allow humans to ascend to your dimensional level?"

“It’s very difficult.”

Saya shook her head.

"The structure of the human brain is different from ours. I'm not sure what my fellow humans look like, but at least the organs I use to sense the outside world are very different from humans. If we want humans to become beings on the same level as me, we need to completely transform them."

"Yeah, that's right..."

Hearing this, Fang Zheng also remembered that in the game Saya once transformed Haruka, a girl who had a crush on Niosaka Yuuki, into the same existence as her. Although Haruka was a beautiful girl in Yuuki's eyes at that time, in the eyes of ordinary people, she had become a monster like Saya.

"Anyway, this matter has finally come to an end."

As he spoke, Fang Zheng turned his head and looked out the window. Through the window, Fang Zheng could see Niosaka Yuki, who was dressed neatly, walking out of the hospital, smiling and clapping with his three friends. In the game, because of Saya's intervention, the four friends who had once been very close eventually fell apart. Haruka, who had a crush on Yuki, was transformed into a monster by Saya, Haruka's friend Qinghai was eaten by Saya, and Qinghai's fiancé Kouji started a life-and-death battle with Yuki.

But now, it's obvious that things won't develop in that direction anymore. I don't know if Haruka would accept Yuki if she confessed to him again.

While Fang Zheng was thinking, Yu Ji seemed to notice his gaze, turned around and looked at Fang Zheng, smiled and waved at him. Yu Ji didn't know what Fang Zheng had done to him, but he was very happy that Fang Zheng was able to save him from that nightmare. At least now, he didn't have to have nightmares anymore.

Seeing Yu Ji's greeting, Fang Zheng smiled and nodded to him, and Saya beside him also waved with a smile. Seeing Saya, Yu Ji was stunned for a moment, then smiled and waved to her, and then turned and left.

"What's wrong? Yuki?"

"Nothing, I was just saying goodbye to Dr. Kasugano. It's thanks to him that I was able to recover..."

Having said that, Yu Ji paused.

"Come to think of it, I just saw a cute little girl next to Dr. Kasugano. Maybe she's his sister."

"Hey? Yu Ji, you're not going to attack the little girl, are you?"

"Are you interested in this? If so, I will call the police!"

"Qinghai, don't talk nonsense, Yu Ji is not that kind of person..."

A group of people left the hospital in a noisy manner, passed by the ambulance with its sirens blaring, and returned to their daily lives.

They will never know what they have missed.

Of course, from this perspective...it might be better to miss it.

“Boom boom boom.”

There was a knock on the door, and Saya was so scared that she quickly retreated behind the screen. Then the door opened and Asakura Ryoko walked in and closed the door.

"Master, I have something to report to you."

"Oh? What's that?"

"Dr. Tanpo Ryoko is investigating something about you."

"who?"

"Tanpo Ryoko, she is also a doctor in the Department of Psychiatry. The two of you have met before."

"Oh... I seem to have some impression of it."

After hearing Asakura Ryoko's introduction, Fang Zheng frowned and recalled for a moment before nodding.

"She's investigating me? Why?"

"It seems to be related to your recent investigation into Professor Oya Yayan. I just ran into her outside by chance, and she wanted to get some information from me..."

As she spoke, Asakura Ryoko smiled harmlessly. As an alien-made human-machine interface, Asakura Ryoko looked no more than 16 or 17 years old. In a hospital, she would be a trainee nurse. Not to mention that she usually behaved harmlessly, elegantly, and innocuously. I guess that's why Dr. Danbo thought she was easier to get.

If she knew that the girl in front of her could rip someone open with a smile, she probably wouldn't have had such thoughts.

"In other words, she is related to Oya Masahiko?"

"It seems so. Doctor Danbao told me that Oya Yayan seemed to have been engaged in some very bad research..."

As she spoke, Asakura Ryoko cast her gaze towards Saya who was peeking out from behind the screen, and the latter stuck out her tongue embarrassedly.

"Well... maybe we can find a chance to talk to her..."

However, before Fang Zheng could finish his words, a sharp scream suddenly came from the corridor outside the door, which scared everyone. Fang Zheng frowned, then he opened the door and looked out. He saw several medical staff pushing a hospital bed and rushing across the corridor towards the operating area on the other side. At the same time, a man was seen tied to the bed. There were burn marks on his face and his hands were struggling desperately, as if he wanted to break free.

"Owner."

Just at this moment, Asakura Ryoko, who had just left the office, came back with a serious expression.

"I asked someone and found out that the patient was a victim of a fire that happened not long ago, and the fire happened at 81 Nagano Road, Kubo District."

"Hmm? Why does this place sound so familiar?"

"Of course it is familiar, because that is the residence of Professor Oya Masahiko, the last place we plan to investigate today."

“…Huh?!”
