Low-Level Civilization? My Fleet Is Going to Turn the Universe Upside Down

[Super technology + climbing the tech tree + genetic evolution + vast worldbuilding + civilization's rise + interstellar war]

Earth in a parallel universe is destroyed. The main body of human civilization, which had already entered the interstellar age, is wiped out, with only tens of thousands of survivors remaining.

Without their home planet's resources, the remnants of humanity are on the brink of extinction.

Ning Yi transmigrates into this world and begins by saving the human survivors on the Moon. He gathers the remaining forces of the Solar System, establishes Mars as his base, consolidates resources, develops technology, and builds an interstellar fleet. Leading the survivors away from the Solar System, he sets out into the sea of stars.

The boundless universe is filled with mysteries and the unknown.

The enslavement and suppression of lesser civilizations by advanced ones is the norm in the development of cosmic civilizations.

Billions of civilizations fight endlessly for survival, as war and destruction sweep across the stars.

The universe is dark and fraught with danger!

How will humanity's reborn civilization face it?
