The Order Gods, for these hundreds of thousands of years, have committed quite a few sins on the Heavenly Mountain.
If it's a relatively powerful God System, the reason they moved into the Heavenly Mountain is that they were invited to enter the plane that matches their attributes on the Heavenly Mountain.

However, some had to seek refuge in heaven due to their lack of strength and inability to withstand demon and devil invasions, and thus, it wasn't so comfortable for them.
Although they integrated their domains into the Heavenly Mountain... But, handing over all external defenses to others, everyone knows the consequences.
