Talking about this, Anying only looked up briefly, and Ye Chen followed suit. It was a ceiling light that usually emitted white light.

But until now, had it not been for Anying's reminder, he would not have noticed that the color of the light indeed had changed slightly, and it seemed to have a hint of redness to it. However, if one said it was turning red, a closer look revealed that the red color had not fully developed yet.

"Ah, if you hadn't mentioned it, I really wouldn't have noticed this slight change in color."

"So, I felt that the lighting conditions when I came in this afternoon were indeed a bit different, and not only here, look at the window over there."

With that, he pointed towards the window, and Ye Chen quickly walked to the window and looked out.

For some reason, he clearly saw a kind of red light imprinted on the window.

"What's with this light?"

He turned back with a puzzled look to Anying.

Anying didn't speak but pointed upwards towards the fluorescent light and then towards the window.

"Do you mean to say, this light should be the reflection from that fluorescent light?"

"Exactly, it projects onto this glass and shows its red light. However, when we observe with the naked eye, we simply can't detect any color deviation in the light."

"It must be said, women's observational skills are indeed very meticulous."

Moreover, when he initially entered, he only focused on the howling wind and the red-colored water, completely overlooking the change in light.

This change, imperceptible to the naked eye, must involve some high technology if it involves changes in the light's reflection, otherwise it could not have been so covert.

"What do you think, does this red-colored water have something to do with the light? Right now, we're just standing under the sunlight and can't see any change. But in the water and on this glass, it can form a mirror effect, so we see red water and red light on the window."

"If we really want to verify all this, then the only option is to go back to the room. I believe everything will naturally come to light."

"Do you mean to say the lights in the room are not controlled? That's impossible. All the circuits come from the same source; if that's the case, then the room would have been tampered with too."

"It depends on whether these people differentiate between public and private areas. If it's a public area, then all the public areas of the entire building can be swapped out."

"If it's just a change throughout all areas, then wouldn't the rooms experience a change too?"

"I think, for a building like this, all areas are probably not connected, which prevents a problem in one area from affecting the power supply in another."

Having said that, he just nodded as he felt assured by his analysis.

"Let's go, let's go back to the room now."

"No matter whether it's true or false, Ye Chen was suddenly very intrigued, and thus he followed Anying and both of them left directly from there.

After returning to the room, the first thing Ye Chen did was turn on the light, then he looked up and noticed that the color of the light didn't seem to change much compared to before.

Finally, he habitually looked towards the glass window but this time he did not see the red light.

"Has my room's light not been tampered with?"

"That should be the case, and think about it if even the lights in your own room would change like this, then anyone staying there for long would definitely notice. It's different in public areas, people won't stay there long enough, and hence they form such misconceptions."

Ye Chen nodded, then took out the bottle of water from his pocket, but when the water was taken out, Ye Chen was stunned in astonishment,

He turned back and looked at Anying, no mistake, what they now saw was indeed a bottle of very clear water, even the color had not changed at all, which one could say was indistinguishable from ordinary water.

"See? The color has returned to normal."

Ye Chen excitedly said to Anying, not expecting that just in this short period he had already unraveled the great mystery behind the water's color change.

"No wonder, previously no matter if people tested the water pipes or the water quality changes, they found no abnormalities, which means the water didn't actually undergo any mutation, but it was a visual impact and error they were seeing.

"Right, it means the real change should be in the kind of light, but how does the change occur in the light?"

"Well, if one isn't studying electrical engineering, it's really hard to explain, and moreover, who would have thought that the color change in water could be related to the light?"

"Additionally, this type of change must be very unique. If it were just a normal fluorescent light situation, then once a person enters, it would certainly be very noticeable."

"Right, so this transformation can only be exhibited on a reflective surface, like flowing water or glass, which both can show the color change."

"Now, we've completely solved the mystery of the water's color change, so next, do we need to find out where this wind noise is really coming from?"

"Actually, I thought about it earlier, the wind noise comes from the ventilation ducts, which should be located at the Main Machine Room, and normally, it's either on the rooftop or in the basement level."

"I've already checked the building's floor plan; it's in the basement level."
