Three-body: The Most Competent Wallfacer in History

"So after the Dark Battle, they fled the Solar System once again.

"One of the spaceships harbored intense hatred for the Solar System State and established the Kindling Star System, but it was soon discovered and assimilated by the Solar System State.

"Another spaceship, P-325, established a starship civilization. They've always been roaming in the universe, only stopping in planetary systems periodically to replenish their resources and add new warships, which is why they were discovered later.

"They've grown accustomed to a nomadic life in the cosmos. Although they're still human, their values and morals have greatly diverged from the main body of humanity, so they could be considered a subspecies of humans."

Then You answered Guan Yifan's question, "The entire Solar System is now like a big city, and Earth is like a garden within this metropolis.

"Since the reconstruction of the Solar System, only the Transdimensional Wallfacer Jiang Yu has lived on Earth for a short period, and since then, it has been a paradise for life forms.

"The stars and planets in the Solar System have always maintained a stable appearance. Historically, the sun has been recharged five times, and its current state is quite similar to when you left the Solar System."

Guan Yifan and Cheng Xin began to walk back and forth unconsciously, as some news was too shocking and they needed to walk around to calm their emotions.

So the group began to stroll and ask questions on the grass, which stretched out far and appeared to extend indefinitely.

Guan Yifan then asked, "What are Transdimensional Wallfacers? In what year did Jiang Yu die?"

You replied, "Transdimensional Wallfacers are Wallfacers who utilize resources from multiple dimensions to address human problems.

"In history, only Jiang Yu had enough prestige and qualifications to be a Transdimensional Wallfacer.

"As for Jiang Yu, he is now in the six-dimensional space, guiding Wallfacers there to commence the work of the new epoch.

"During the Galaxy Era, he had already gone to higher dimensions, continuously striving for a better future for humanity."

Guan Yifan and Cheng Xin were both taken aback. The fact that Jiang Yu was still wielding great influence over humanity was unexpected to them.

The two fell silent with no new questions, and it was only when Sophon asked that they spoke again, "What about the Trisolarans now? Why didn't we find Earth's language and script in the Return Movement?"

You also answered Sophon's question: "The Trisolarans' main activity region is roughly 5 light-elements away. Oh, it seems you are not familiar with the concept of 'light-element,' let me explain what it is first.

"In The Second Epoch, three-dimensional humans had already achieved immortality, and the term 'year,' back then the largest unit of time, was insufficient for people's needs.

"Also, as human spacecraft speeds increased, light-years were no longer adequate as a unit of distance.

"So, based on light-years, people created many new units of distance.

"One thousand light-years is one light-migration, one thousand light-migrations is one light-conjunction, one thousand light-conjunctions is one light-element, and one thousand light-elements is one light-combina.

"If we were to convert using the light-years you're familiar with, 5 light-elements would be 5 billion light-years."

This explanation left Guan Yifan and the others in inward astonishment; in their era before entering the micro-universe, even 50 light-years was considered a long distance.

And now, the units for distance and time were always multiplied by a billion?

You first gave a brief account of humanity's victory over the Trisolarans during the Galaxy Era, then explained further:

"In The Third Epoch, the surviving Trisolarans established normal diplomatic relations with humans and accepted human protection. Currently, the Trisolarans have reached the standard of an advanced civilization."

Sophon found this outcome hard to accept; before entering the micro-universe, the Trisolarans were very powerful, at least by their own assessment, believed to be somewhat stronger than humans.

It seemed You noticed Sophon's confusion and therefore sent over an analysis of the Trisolarans from the Galaxy Era, along with a comparison between the two sides.

After quickly completing her 'reading,' Sophon felt the Trisolarans hadn't lost unfairly.

Firstly, the control and mobilization abilities of the Solar System State were beyond what the Trisolarans could match.

Moreover, Jiang Yu had always emphasized unity as core to humanity's competitive strength.

Humans individually might be weak, but the collaborative strength between humans was immense.

This excellent tradition had been maintained up to the present.

You continued, "As for why human language and script didn't appear in the 'Return Movement' data you received,

"it's because humans were the initiators of this movement, and so far, not a single human has been in a micro-universe—a fact worth being proud of.

"Before then, to avoid Dark Forest Strikes, humans had repeatedly entered micro-universes en masse, but all without exception have returned.

"Therefore, there was no need for human language to appear in the 'Return Movement' documentation."

Guan Yifan was more concerned about the current state of the universe, "How is the universe doing now? Is the mass close to falling below the critical point?"

You: "Based on our observations, we're still quite far from the critical point.

"It's just that the micro-universes of some civilizations have caused the macro-universe to lose a lot of mass, leading to imbalances in many areas of space and a rise in instability.

"That's why we initiated the 'Return Movement,' which is also a warning to those within the micro-universes!

"If they ignore this and don't return the mass of their micro-universes, we will use force to completely 'dismantle' those micro-universes."
