Lu Yuan knew very well.
The impact of severing the heavens is not limited to Earth.
It envelops the entire Galaxy Star Realm.
Even though the power is gradually weakening, it still restricts beings at the saint level.
The reason is simple: the ancient sages knew that power below the saint level would not cause significant harm to this world, but above that, it would be completely different.
Therefore, from the beginning till now, the strongest beings appearing outside have been at most at the Great Saint level.
Otherwise, those ancient immortals wouldn't have chosen to merely reflect their power.
They would have chosen to descend personally.
Precisely because they couldn't.
As for why Lu Yuan believes that only after breaking into the Great Saint Realm can he intimidate all Outer Realm Creatures and be invincible in the starry sky,
the reasoning is straightforward: even though he believes he is invincible in his own realm, he has never underestimated his enemies.
