Over the years, human civilization has discovered four-dimensional cavitation structures in the Shapley Supercluster and used these cavitations to master dimensional ascension technology.

This four-dimensional vacuole is approximately 100 light-years in size and contains numerous star systems.

The state of these stars indicates that this four-dimensional cavitation has existed for an extremely long time...

Before the introduction could finish, the Cleaner civilization sent a tachyon message, interrupting the human civilization: [Wait! Are you sure the four-dimensional void is 100 light-years in size?!]

"Of course," Lü Yongchang, aboard the Earth, gave an affirmative answer, then countered with, "Isn't this what you discovered about four-dimensional cavitation?"

[...less than a light-year.]

Looking at the text in the holographic projection, Lü Yongchang fell silent.

No wonder the Cleaners civilization failed to discover the truth about the pastoral society from the four-dimensional bubble.

A four-dimensional void with a size of less than one light-year... It can't even fit a single star system!

He skipped that topic and continued his presentation.

In these four-dimensional star systems, we discovered numerous remnants left by advanced civilizations.

Subsequent research indicated that these ruins belonged to an advanced civilization called Troy.

Human civilization retrieved a still-functioning information recording device from the ruins, which contained records of the history of the Trojan civilization.

Although there is no direct evidence, based on the various descriptions, we believe that the Trojan civilization had an extremely close connection with the Pastoralists, and may even have been their leader!

The moment the words were spoken, the large transport ship had already come to a stop on the public research platform built by human civilization.

A four-dimensional hypercube device, heavily protected by a dark matter stabilizing field, is clearly presented before the eyes of all advanced civilizations!

P.S.: The plot is mostly sorted out now, and I'll resume two updates a day tomorrow.
