In the past, his Void Realm wasn't at its pinnacle, so he definitely couldn't erase Sheng Yuan's consciousness.
As for using the clones for battle.
Lu Changsheng advanced to Immortal Venerable, but there was no increase in the clones.
There were still only forty-nine thousand clones.
If the Void Realm indeed wasn't at its pinnacle, it would be hard to tell who would win between Lu Changsheng and Sheng Yuan.
Of course, even if Lu Changsheng couldn't do anything to Sheng Yuan, Sheng Yuan certainly couldn't deal with Lu Changsheng either.
But with Lu Changsheng's Void Realm reaching its pinnacle, things were different.
Facing Sheng Yuan would be an absolute crush.
With the Void Realm at its pinnacle, now Lu Changsheng, at the Immortal Venerable level, would crush any Ghost Race opponent!
This is true invincibility at the same level!
However, Lu Changsheng did not rush to sweep through.
He just found a place on the battlefield.
