Beginning with Supreme Ones, the foundation of a living being's existence shifted from the flesh and Primordial Spirit to the Great Dao.
For those Great Powers who had existed before attaining the Dao, killing them in their weaker years would still leave their Dao nature intact.
Were they dead?
They were indeed dead.
But such a death was not complete. They could still return.
The same held true for Great Powers born having already attained the Dao. Their Dao nature could not be destroyed; this, too, was a law of the Great Dao.
Space-Time could not be traversed from end to end, but Dao nature endured.
Besides, if Meng Chuan truly wanted to kill a Supreme One or a Chaos One, he could erase their Dao completely in the outside world.
Why go to all this trouble to kill them here...
And Limitless Ones could not be killed at all.
Suppose a Supreme One could come here. If he faced a Great Power in their weaker years, killing them would not erase their Dao.
If he faced someone born divine, and could erase their Dao here, he could surely do the same in the outside world.
And if he faced someone born divine who had already reached Chaos Level outside...
If they could attain Chaos and he could not, it was obvious who was stronger. In a fight at the same level, killing him would be as easy as killing a chick.
The same held true if a Chaos One came here.
There was no point in killing someone if he could not kill them completely.
If you happened to come here and killed someone in Origin Space-Time, it was you who struck, not the Great Dao.
Do not elevate an individual act into an act of the Great Dao.
