The villainous magical girl's daily mission is to find fault.

In most events, stargazers are the most likely to remain seated.

They possess abundant knowledge from the celestial realm and have a professional school training model. Most events that seem intimidating may just be insignificant matters in the eyes of stargazers.

However, if the stargazer displays confusion, tension, or even silence, it often indicates that the situation has entered a realm that cannot be explained by ordinary circumstances—

"Why aren't you two saying anything? What happened? Tell me quickly!"

Upon returning to the real world from the alternate dimension, Hyacinth hurriedly asked the two stargazers floating in front of her a question.

The white sable spirit and the fox spirit fell silent at the same time, a rare occurrence, and their gazes as they looked back at the hyacinth were quite complex.

"Listen, Hyacinth," Yue Tianxin flew to Hyacinth and said quite seriously, "We need to find a quiet and safe place to explain to you, but you must promise to keep what happens next a complete secret. You absolutely cannot tell anyone except us, understand?"

Hyacinth froze, a strange unease rising in her heart, before nodding repeatedly.

No matter how unreliable Hyacinth may be, she is still completely trustworthy when it comes to keeping secrets.

Bai Ling pulled her aside, and Nightingale, Iris, and the others followed suit, chattering and gesturing wildly at the edge of the court, trying to explain to the people in front of them the series of conclusions they had drawn in the other dimension.

Meanwhile, Yue Tianxin flew to Hellcat and Xinyuehu. The cat girl crossed her arms and watched as the two foxes, one big and one small, huddled together, talking nonsense and exchanging information efficiently in a manner similar to encrypted communication.

Tail Network's primary terminal is uploading information to the host at high speed.

Once the high-speed bandwidth communication on the tail network was complete, Su Tianqing switched Yue Tianxin to automatic mode. While she turned to explain in detail to the cat beside her who hadn't understood at all, Bai Ling was still stuck on the first step—

The fox spirit quietly flew behind Bai Ling, stunned by her thunderous speech:

"Oh dear, why don't you all understand? The essence of this alternate dimension is a high-dimensional vector manifold projected onto the plane crystal wall by the domain of the anti-Mistra-Bernuk space..."

"...Senior Bai Ling, let me explain."

Su Tianqing was somewhat glad that she had switched Yue Tianxin to automatic mode in time. If it had been manual, she might have already reached out her fox paws to knock Bai Ling's head.

"Ah, Xiaoyue, you're here. Xiaoyue, quickly explain to Shuoye and Tiannanxing. Iris and Hyacinth don't seem to understand either."

"Report, actually I didn't understand much either, I only understood the general idea." Nightingale also raised her hand in a daze, her expression suggesting that she had just experienced a baptism of knowledge.

The white ferret shook the fox spirit's shoulder with a pitiful expression. Yue Tianxin nodded with a wry smile and flew to Tian Nanxing and Shuo Ye, whose heads were already bubbling with excitement. The magical girls then began to explain earnestly.

And so on, and so forth, babbling on and on, talking nonsense.

The nightingale's narrowed eyes gradually widened, revealing an expression of sudden realization.

Iris and hyacinth nodded thoughtfully, occasionally asking a few questions to illustrate their points. After Yue Tianxin answered them one by one, they couldn't help but nod in affirmation and agreement.

Shuo Ye and Tian Nanxing were initially confused, but after Yue Tianxin began to explain, their drooping tails immediately started wagging vigorously, and their amber owl eyes became much brighter.

"So that's how it is! I understand completely now!" Tian Nanxing clapped her right fist lightly with her left hand, and her tail wagged like an electric fan.

This time, Bai Ling was the one who was completely bewildered, her gaze towards Yue Tianxin filled with admiration.

"Wow, that's amazing! Xiaoyue, how did you explain it so clearly to everyone?"

"Because you're talking about advanced magic, Bai Ling. I've only just started learning it, how can anyone understand it?" Nightingale couldn't help but ask back.

"Hmm... but that's what Senior Mengmeng told me." Bai Ling scratched her head.

Yue Tianxin's teaching level was rated as "amazing," while Bai Ling's teaching level was rated as "utterly terrible."

With the stargazers' detailed explanations, the nature of the alternate dimension was gradually revealed.

"It was a fragmented, collapsing mental world," Su Tianqing explained to Hellcat in one sentence.

"Unlike my current mental image, it doesn't have a complete customization function. It's similar to the old versions of mental images by Red Rose and Crimson Snow, which can only use real-world buildings and terrain as a basis to construct a world similar to a real-world city in the mental image."

"If nothing unexpected happens, that alternate dimension is a mental world, except that the architecture and terrain it chose are Chengdu from ten or twenty years ago, exactly the same as Chengdu at that time, which is why it presents a dream core feeling of the millennium."

"We can propose a hypothesis that this alternate dimension was actually constructed more than a decade ago, but it has been operating in an unknown place until now, which is why it appears as Chengdu in the past."

"I see……"

Hellcat squinted for a moment, then said:

"Does that explain why you didn't notice it immediately, Fox?"

"Yes, because it existed long before I could use the mental image world. In addition, when I first used it, I didn't have a strong perception of other mental images, and it was covered by several layers afterward, which is why it was hidden."

This would explain the existence of spatial rifts.

The mental world is not permanently stable; it will gradually deteriorate over time. It requires the caster to maintain it both internally and externally to ensure its existence. Otherwise, the separation between it and the real world will gradually weaken, or even break through, creating spatial rifts that connect the inside and outside.

If it's a custom-designed mental world, it's relatively easy to maintain, since creators can change the terrain and buildings at will without any spatial errors.

Replicating the mental image of existing buildings is more complicated. It requires comparing the layout of existing buildings to carry out repairs. In addition, Chengdu's urban planning has been constantly changed over the years of renovation and reconstruction. The original old city has been replaced by the CBD new city and other high-rise buildings and shopping malls, and the appearance of the millennium can no longer be seen.

Multiple factors combined, along with the giant hydra that inexplicably exists in another dimension, caused all the problems to erupt at the same time, resulting in the current situation:

The caster of the mental image neglected to maintain it and could not find anything to compare and maintain it. As time went by, the mental image world gradually deteriorated, and finally collapsed and formed cracks today. The giant hydra finally found a place to extend its tentacles into the real world, which is the semi-transparent arm seen in the alley.

"If that's the case, why don't we just eliminate that giant hydra? Didn't Hyacinth and Akashi take it down with them yesterday?" Hellcat asked.

"At first, you and I had the same idea, but do you remember how strange Akashi and the others looked when Hyacinth went in today?"

The Hellcat paused briefly, as if it had remembered something.

Yesterday, Chi Xue fought alongside Hyacinth, but today she acted as if she didn't recognize her at all, as if she had no memory of Hyacinth whatsoever.

"Based on the information brought out by Yue Tianxin and Bai Ling, I can propose a rather bold hypothesis—"

"It's not that Akashi lost her memory, but that her time was reset."

"This alternate dimension is not a simple mental world at all; it is an endless cycle."

The fox spirit was silent for a moment, then murmured softly.

"...the cycle of death."
