Gu Xingmiao had no awareness that she lived in a strange nest.

Apart from the cobwebs always covering the ceiling, the occasional light bulb failure, and the curtains being closed most of the time... everything was pretty normal.

01 Originally, he wanted to talk to Gu Xingmiao about the reason why her pollution value was so high, but seeing this situation, his attention was mostly attracted by the house.

"Generally speaking, a house doesn't need to be cleaned repeatedly." As she said this, she picked up the cleaning tools and swept away the spider webs.

She brought the spider web thread down with her.

There is indeed a faint smell of pollution on it, but it is definitely not strong. This level of pollution is the mild pollution that may occur in every resident's home.

There seemed to be a flash of surprise in 01's eyes. She didn't expect that she had made another misjudgment.

"There's something in this room!!!"

"Great! Finally someone else noticed something was wrong with the house. This house is just weird. Doesn't anyone remember the black air rising from behind Gu Xingmiao when she was writing a story in the room before?"

"I remember! I remember it. It was terrifying, like some kind of evil spirit. Holy crap, it's still in the host's house!"

"Given Sister Gu's personality, once the teacher pointed out a problem, she would rather kill the innocent than let him go. After that, she would definitely observe the surroundings quietly."

Gu Xingmiao didn’t think that 01 had made a wrong judgment.

She is not very sensitive to pollution, one could even say she is dull; 01 Since she feels that something is wrong with the house, maybe there is something hidden in it?

Gu Xingmiao thought vigilantly.

"Do you need to report to the alliance and have someone come and inspect the room?" 01 said seriously, "Although I haven't found anything wrong with the house yet, it's too depressing and really not suitable for recuperation."

Of course Gu Xingmiao knew that the disease she was talking about was his own pollution.

She smiled helplessly: "If you, teacher, can't find any problems, then those who come to review the room shouldn't find any problems either."

01 He paused for a moment and felt that what Gu Xingmiao said was right.

"Forget it, this is not the most important thing. I want to know why your pollution is so high?" She sat down again and stared at Gu Xingmiao straight in the eyes, not missing any expression on her face.

"Since you allowed me to bring you out, I naturally believe that you can control your pollution level yourself, and you can control it very well." 01 analyzed calmly, "Besides, your pollution level must have been elevated a long time ago."

"Is it when the first copy of Ancient Earth appeared?"

"Or was it when we encountered the Sun-Chasing Giant on ancient Earth?" She pressed the question, not allowing her to evade.

"This teacher has such terrifying insight. Even before Gu Xingmiao said anything, she had already guessed many things close to the answer."

"If Gu Xingmiao wasn't a time traveler, then I'm afraid that guess would really be correct."

"Although the live broadcast room is broadcasting the entire process, even those in our room only recently learned that Gu Xingmiao's pollution level is so high, okay? This is really terrifying when you think about it..."

The corners of Gu Xingmiao's mouth rose slightly, but even 01 couldn't tell where the suppressed and heavy emotions came from in his eyes.

She is just an 18-year-old girl from the Alliance, why is she feeling so sad?

It was clearly a faint smile, but it made the smile on 01's face become fainter and fainter, almost to nothing.

"I think you must have already investigated my situation, Teacher 01." Gu Xingmiao's tone was steady, and his expression became calm. "I know you can't find the answer, so you ask me directly for an answer."

"I can answer your question, but I also want to know a question. I wonder if we can exchange a question?"

01 said with a forced smile, "Gu Xingmiao, if I remember correctly, it was me who got you out of the school clinic. Otherwise, you would have had to stay in bed for a full month, waiting for the pollution level to drop before you could come out..."

"And can your pollution level really be reduced?"

"What does this teacher mean? Do you know that there's something wrong with Gu Xingmiao's pollution level?"

"No, if 01 really knew Gu Xingmiao's specific situation, he wouldn't be like this. Wouldn't he have just been able to figure it out directly? They're just testing each other."

"It's just a game. They seem to be chatting about nothing, but everyone has their own thoughts. It turns out that no one who survives in the future is a fool!"

Gu Xingmiao's expression did not change when he heard this.

Her fingers, gently holding the nutrient solution, trembled only slightly. She drank a mouthful of the unpalatable solution without changing her expression, and then said, "Teacher, I just want to know the secret of the Great Dark Age."

01 laughed in anger: "This sounds like a really bad deal."

Gu Xingmiao just looked at her even more quietly.

The room was silent for a long time.

"Okay, it's not that I can't tell you, but I told you that your pollution level can't accept this knowledge. I can try to tell you when your pollution level drops." 01 said helplessly.

She thought about Gu Xingmiao's stubbornness, but seeing her so stubborn was exhausting.

What's the point of teaching a student? It's more tiring than fighting with monsters.

Students should not only take care of her mental health, but also pay attention to her personal safety——

In previous years, the alliance had never assigned her any students, believing that her pollution level was too high and that if anything went wrong, the students would be killed by her.

But now 01 finds that there is always a mountain higher than the other.

"Okay." Gu Xingmiao agreed quickly. Her look made 01 speechless and gave him a headache.

"My pollution value has always been high, but it seems to be different from that of others..." Gu Xingmiao said after a moment of hesitation.

Eighty percent makes 01 very worried, so it is better not to tell her one hundred percent for the time being, but to tell her some things based on the eighty percent.

So, Gu Xingmiao talked about the peculiarity of his pollution value.

Most of the time, it maintained a stable high value, almost never dropping. The only time she realized her pollution value was so high was when she encountered space-time turbulence during her first mission to Ancient Earth...

I didn't expect that the pollution level would increase after I woke up/I would travel through time.

01 frowned in confusion.

"That doesn't sound like a reason for elevated pollution levels."

Gu Xingmiao shrugged: "I think so too, but the pollution level was indeed very high at that time, even exceeding 80%."
