This endless world

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

The answer is, too many to count.

After recognizing Yang Yun's face, Xue Na's expression was extremely complicated. Confusion, shock, joy, surprise, sadness, crying, disbelief... Countless emotions appeared on her beautiful face at the same time. It looked like she had opened a large dyeing workshop, completely losing her previous cold posture.

"you……"

However, as soon as Xue Na asked a word, she suddenly covered her forehead, as if someone had hit her head hard. She was obviously extremely powerful, but at this moment, Xue Na seemed to be unable to control her body at all. Her whole body swayed and she fell down——

——Then, Yang Yun, who had expected it, stopped and supported her, and then the fairy spiritual power was passed along, turning into green light to warm Xue Na's body.

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

Yang Yun took a look and knew that the current situation of Xue Na was exactly the same as his previous situation. Both were hit by an extremely large amount of memories in a moment, so that they could not control their bodies: "Think about it carefully, it should engrave everything." It got into your mind..."

"...What on earth is going on?"

Enveloped by Yang Yun's healing beam, Xue Na's expression was visibly relieved. The girl who had been sleeping for eighteen thousand years rubbed her temples and gritted her teeth and said, "Why is it in my mind?" There is a memory that does not exist at all? When my mother and I fled the primitive continent 18,000 years ago, you were absolutely nowhere to be found. I can absolutely confirm this!"

"Moreover, my memory has no traces of being sealed or tampered with, but this memory is so real and true..."

The more Xue Na thought about it, the more impatient she became. It was obvious that this sudden extra memory caused a lot of trouble to her: "Eighteen thousand years ago, it was my mother who took me..."

But when Xue Na was halfway through speaking, she suddenly got stuck, and her originally smooth words could no longer continue... Because at this moment, she suddenly realized that the only things she could recall were "two people" It was just the result of "Finally escaping from the ancient continent", but the specific process, method, and details could not be recalled!

"Yeah, what's going on?"

Zheng Zha on the side scratched his head and raised his own question: "If Yang Yun, your return to history is an inevitable step in historical development, then Xue Na should have recognized you at a glance when she first woke up...otherwise Isn't there still a timeline where Yang Yun returned to 18,000 years ago through the time and space corridor, but the Human Emperor was still forced to retreat? "

"Although I don't know much about it, only you, Yang Yun, can do what happened before. There shouldn't be any 'original timeline'... Is it Dr. Manhattan's saying of 'Characters first, then stories'?" A set? But it’s impossible to have a present without the past, right?”

"...I think this may be the influence of the 'protagonist''s personality."

Yang Yun supported Xue Na, pondered for a while, and then slowly said: "It's not that there is no 'past', but that the 'past' is in a special superposition state. It requires observation by people with special qualifications to finally determine ”

Recalling the conversation between Human Emperor Pei Xi and Tongtian, Yang Yun also had deeper thoughts on the existence of the "protagonist": "The Emperor and the Inner Universe are both creatures that can play games on the timeline. At their level, Existence has become difficult to view from a low-dimensional perspective... They can change the past, shape the present, and determine the future, making everything impossible to completely determine. Both the past and the future are only possibilities that can be changed. "

"Unless there is a special person like the 'protagonist' who observes the possibility, the real 'fact' will be born..." Yang Yun speculated with some hesitation, "Maybe even before we entered this ruins, Xue Na It can only exist inside that giant egg, in a superposition state of neither life nor death."

"...What do you mean? Is it the 'Schrödinger's cat' thing again?" Zheng Zha, a scumbag student, asked.

"The Box Theory."

Fortunately, Chu Xuan spoke immediately and explained to Zheng Zha: "The main god space is a box within a box, with relatively independent laws and regulations. Therefore, even in the world of Immortal Sword, the three emperors are Shennong rather than Hou Tu, which is the same as the previous one. The universe that is closely related to the era can also exist in it, and the cause and effect of the Kunlun ruins are completely cut off from the outside world, so it is not surprising if the reality here is inconsistent with the outside world. "

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

Yang Yun analyzed: "The reason why he did not do this may be because he did not see me in the past. From the Human Emperor's point of view, he has completely obliterated Arthas and Xena in most of the timeline, but But someone hid the infinite possibility that Xena and Alsace survived in this ruins... just like a hidden route in the game. "

"Until we discovered it, this possibility became an anchored reality. Then I was sent back to the past, and the past was truly rewritten, making the timeline completely coherent, and it became a trend that even the Human Emperor could not change. If not, 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 way I saved Zhang Jie. I rewrote Zhang Jie's origin story by letting the "positive person" observe Zhang Jie's fabricated past. Perhaps this is a "foreshadowing", just like Xin Bian lent me power and the Purple Thunder Blade, just so that Tongtian could Relying on miracles to transfer the light of the soul to me, thus turning the world around 18,000 years ago and completely fixing the 'past'. "

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

"Compared to planning, it's better to say that it's going with the flow. After all, whether it's saving Zhang Jie or being recognized by Xin Bian, it's all based on my own decision. She just made me appear in the right place at the right time and meet the right person. "

Thinking of the roulette wheel that appeared at the feet of the 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?"

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