The Heavenly Position is already at the pinnacle of supremacy. If the Heavenly People Clan has countless Heavenly Position strong people, it would make sense that in that ancient war, only the master and mistress managed to escape unscathed.
That battle must have been shocking, even compared to the invasion of the Four Extremes World by those God Demons during ancient times, when their powers were suppressed by the World Laws. The Heavenly People Clan, favored by the Heavenly Dao, had no decrease in power.
If they had launched an attack with countless Heavenly Position strong people,
and if they had also utilized powerful formations and magic treasures, at that time, even the Primordial Heavenly Emperor would have been powerless to reverse the situation.
They could only rely on the advantages of timing, terrain, and unity to keep them out.
