Just outside of Purple Fungus Planet, those nebulae appeared to be very close but were in fact far away.
They traveled a long distance to enter a nebula. The so-called nebula was actually composed of countless interstellar dust and gas.
It seemed to be dense from a distance, but in fact its density was very low.
After entering one, it was as if nothing was there.
Only in many special areas attracted by heavy nuclei would the density of the nebula suddenly become higher and opaque, making it difficult to see what was inside.
Most of these heavy nuclei were condensed from various planet fragments.
The monsters, which originally seemed to be very close, traveled through these areas, fighting with the monsters inside.
