The Horned Dragon Star was located at the Three Coves Quadrant. It was extremely far from Earth, and even Golden Immortals adept at Dimensional Dao would need one month to reach Earth even if they teleported, should they choose not to use the warp portals.
With the portals, however, they would need just three days to reach Earth.
Naturally, that was because the portals on Mars had all been destroyed, or the immortals could have arrived directly on Mars with long-range warping.

He paused for a while beyond Earth, looking down upon the grotto-heavens, which flickered with immortal glimmer and frowned slightly.
