Over the next few decades, humanity discovered more planets with life.
Some planets had animals; others had intelligent beings.
The intelligent beings resembled octopuses, with eight tentacles and grayish-white bodies. They had no technology, but they could use Nen.
Odin looked at those octopuses. "Starry Sky Octopuses?"
They were not Starry Sky Octopuses, but another species.
They were much smaller, only half a meter long. They possessed energy, and quite powerful energy at that, but it was not Nen.
Odin's subconscious had probably brought this species into being.
Time flew by as he watched.
Humanity's technology grew increasingly advanced. Antimatter Engines gave way to Spatial Engines, which could jump directly between two points without needing to fly.
A spaceship departed from Earth and activated its Spatial Engine. The surrounding space warped, and then the ship vanished.
The next second, the ship appeared beside a star several light-years away.
Odin raised an eyebrow, but he was not surprised.
At this level, such capabilities were nothing unusual.
But humanity's technology was still crude, and its energy consumption was somewhat high.
Humanity continued to expand. A few centuries later, it had colonized half the galaxy.
Tens of thousands of stars, hundreds of thousands of planets, and tens of trillions of people.
Their technology became increasingly outrageous.
They built Dyson Spheres, enclosing entire stars to absorb all their energy.
They created artificial black holes and used them as power sources.
The black holes were tiny, only the size of a fist, but their mass was several times that of Earth.
Energy streamed from the edges of the black holes, dazzlingly bright.
They built Matter Converters that could turn one substance into another.
Stone into gold, water into oil, carbon dioxide into oxygen.
They developed faster-than-light communication, allowing real-time conversations across tens of thousands of
