South-Heaven Gate.
The South-Heaven Gate was the name of an uninhabited planet that was located to the south of the star map where the abandoned world was located.
A long time ago, this was the second last stop on an ancient path through space. It had once been prosperous, and some creatures had built cities there.
Now, traces of the space teleportation platform could still be found on the surface of the planet, but it had long been abandoned and could not be used.
The main reason was that after 10 million years, the coordinates of the entire galaxy had changed greatly. The wormhole had either disappeared, or the direction and location had already changed.
The existing space paths in the Hidden Dragon Galaxy were also built around the location and direction of the wormholes. Many of the transit planets along the way were even man-made.
