this infinite world

——How many different emotions can appear on a person’s face?

The answer is countless.

After recognizing Yang Yun's face, Xue Na's expression was extremely complicated. Confusion, shock, joy, surprise, sadness, crying, incredible... Countless emotions appeared on her beautiful face at the same time, and she looked like she had opened a big dyeing factory, completely different from her previous cold attitude.

"you……"

However, when Xue Na just asked a word, she suddenly covered her forehead, as if someone had hit her head hard with a hammer. Although she had extremely strong strength, at this moment Xue Na seemed to be unable to control her body at all. She swayed and fell down.

——Then, Yang Yun, who had anticipated this, held her by the waist, and his spiritual power was transferred to her, transforming into a green light that warmed Xue Na's body.

"I think it's not appropriate for you to think too much right now, so you should adjust yourself first."

Yang Yun knew that Xue Na was in the same situation as he was before. They were both hit by a huge amount of memory at once, so that they could not control their bodies. "Think about it carefully. It should have engraved everything into your mind..."

"……What exactly is going on?"

Enshrouded by Yang Yun's healing beam, Xue Na's expression was visibly relieved. The girl who had been sleeping for 18,000 years rubbed her temples and gritted her teeth as she said, "Why do I have a memory that doesn't exist in my mind? When my mother and I fled the prehistoric continent 18,000 years ago, you were definitely not there. I can absolutely confirm this!"

"Moreover, there is no sign of my memory being sealed or tampered with, but this memory is so real..."

The more Xue Na thought about it, the more anxious she became. It was obvious that this sudden memory had caused her considerable trouble: "Eighteen thousand years ago, it was clearly my mother who took me..."

But when Xue Na was halfway through her speech, she suddenly got stuck and could not continue her fluent speech... Because at this moment, she suddenly realized that the only thing she could recall was the result that "the two of them finally escaped from the prehistoric continent", but she could not recall the specific process, method, or details at all!
"Yeah, what's going on?"

Zheng Zha scratched his head and raised his own question: "If Yang Yun's return to history is an inevitable step in the development of history, then Xue Na should have recognized you at first sight when she woke up... Otherwise, wouldn't there be a timeline where Yang Yun did not go back to 18,000 years ago through the time corridor, but the Human Emperor was still forced to retreat? "

"Although I'm not too sure, but only you, Yang Yun, could have done what happened before. There shouldn't be any 'original timeline'... Could it be that Dr. Manhattan said 'characters come first, then stories'? But it's impossible that there would be the present without the past, right?"

"...I think this may be the influence of the 'protagonist's' status." Yang Yun supported Xue Na, pondered for a while, and slowly said: "It's not that there is no 'past', but the 'past' is in a special superposition state. It needs to be observed by people with special status to be finally confirmed."

Recalling the conversation between Emperor Pei Xi and Tong Tian, ​​Yang Yun also had a deeper thought about the existence of the "protagonist": "The Emperor and the Inner Universe are both creatures that can play games on the timeline. Their existence at this level is already difficult to view from a low-dimensional perspective... They can change the past, shape the present, and determine the future, making everything impossible to determine. Both the past and the future are just possibilities that can be changed."

"Unless there is a special person like the 'protagonist' who observes the possibility, the true 'fact' will be born..." Yang Yun speculated hesitantly, "In fact, it is possible that before we entered this relic, Xue Na could only exist inside the giant egg, in a superposition state of neither life nor death."

"…What do you mean? Is it the same old 'Schrödinger's cat' thing again?" asked the poor student Zheng Zha.

“The box theory.”

Fortunately, Chu Xuan spoke up and explained to Zheng Zha: "The main god space is a box in a box, with relatively independent laws and rules, so even the universe like the Fairy Sword World, where the Three Emperors are Shennong instead of Hou Tu and are closely related to the previous era, can exist in it. The cause and effect of the Kunlun Ruins are completely cut off from the outside world, so it is not surprising even if the reality here is inconsistent with the outside world."

"Yes, that's right. 'Kunlun' is part of the Tower of Babel and has similar functions to the main divine space."

Yang Yun analyzed: "The reason why he didn't do so might be because he really didn't see me in the past. In the eyes of the Human Emperor, he has completely wiped out Arthas and Xuena in most of the timelines, but someone hid the infinitely close to zero possibility that Xuena and Arthas were lucky enough to survive in this relic... just like a hidden route in the game."

"It was not until we discovered it that this possibility became an anchored reality. Then I was sent back to the primitive past, which truly rewrote the past, making the timeline completely coherent, and becoming a trend that even the Human Emperor could not change. If not for this, the Human Emperor would probably have desperately searched for the traces of the Zhongzhou team in the entire multiverse before we entered this plane, preventing me from seeing Xue Na, Arthas, and Gong Yeyu, and strangling everything before history became a fixed point in time and was completely determined..."

"Now that I think about it, this is the same method I used to save Zhang Jie. I had previously rewritten Zhang Jie's origin story by letting the 'positive one' observe Zhang Jie's fabricated past. Perhaps this is a 'foreshadowing', just like Xin Bian lent me his power and the Purple Thunder Blade so that Tongtian could transfer the light of his soul to me through a miracle, thus turning the tide 18,000 years ago and completely fixing the 'past'."

"...You mean, all of this was planned by someone?" Zheng Zha frowned and asked, "Who?"

"Rather than planning, it's more like going with the flow. After all, whether it was saving Zhang Jie or being recognized by Xin Bian, it was all based on my own decision. She just put me in the right place at the right time and met the right person."

Thinking of the roulette wheel that appeared under the feet of Human Emperor Pei Xi, and the skinny little girl in the memory of "Nong", Yang Yun closed his eyes and exhaled deeply: "...Who else could it be?"

"Of course it's the last of the Three Emperors, the Queen of Earth." (End of this chapter)
