In the Milky Way, there's an unremarkably positioned region.
This region spans a few hundred light-years; not too big, not too small, and it's called the Orion Arm.
However, this region has a distinctive feature, which is a nearly invisible barrier that protects hundreds of light-years, making it nearly impossible for any life form to get in or out.
But this barrier has exceptions, which is a gap somewhere outside the barrier, beyond which is a small interstellar area named the Starlight Domain.
This is an area spanning tens of light-years, containing hundreds of stellar systems, and naturally, it also has civilizations and beings.
"Lord Jia Yan, I never expected, after all these years, to return to this place one day."
A turtle-like green creature stood at the edge of that barrier, looking at everything outside, almost in tears.
Not far from him floated a small figure, just like him, hovering in the air.
It happened to be Jia Yan's Avatar.
