The Primordial Wilderness had a River of Time through which one could travel into the past and future. But clearly, not even the Sages of days to come could manage that!
Even Hongjun and Yang Mei, as they were now, did not dare to truly travel into the past or future.
The Primordial Wilderness contained the Complete Time Source Great Dao. Not just anyone was qualified to wander through the Primordial World's past and future.
The Heavenly Dao allowed Daluo Golden Immortals and cultivators below them to travel into the past, but not the future.
As for Heavenly Dao Sages and Primordial Daluo Golden Immortals, it did not even allow them to travel into the past.
The past was already set. If Sages or Primordial Daluo Golden Immortals could roam through it at will, who knew what might change?
The Heavenly Dao might not care about minor events, but a change to the course of history would be another matter entirely.
So the Heavenly Dao imposed a blanket ban.
Daluo Golden Immortals could roam through the past because, even if they did, they could not change much. They might alter minor events in a small area, but the Heavenly Dao did not care about those.
Sages and Primordial Daluo Golden Immortals were barred from the past because they were too powerful.
The Heavenly Dao could suppress the Primordial Wilderness across the ages, but Sages and Primordial Daluo Golden Immortals wielded such immense power that even a moment's inattention might let them change the course of history.
True, the Heavenly Dao could repair the damage afterward and punish them.
But it evidently found that too troublesome, so it imposed a blanket ban.
Of course, it could only do so because the Primordial World contained the Complete Time Source Great Dao.
