Meng Chuan had chosen to enter Dao Union of his own accord. Though he would ultimately vanish into the Great Dao, he would retain some control until a certain point.
While he still had that control, while his sense of self still existed, he could gradually build up a tolerance for the Great Dao.
That was different from being subject to Great Dao Assimilation in an instant.
Even a little tolerance might one day prove crucial to Meng Chuan's Transcendence.
It would also let him retain his sense of self longer as Dao Union progressed.
After all, having it was better than not having it.
Besides, the Great Dao in its current state was "softer," more "docile," and easier to work with.
Within the First Origin Point, the Great Dao had briefly entered a state that preceded even its Prototype.
That was why Meng Chuan had chosen to enter and begin his path of Dao Union here.
He had not gone straight to unite with the Great Dao Matrix outside, or with the Great Dao Prototype that was taking shape.
Here, he had more room to act. His Dao Union could also be more thorough and complete.
If he directly merged with either the Great Dao Prototype outside the Origin Point or the complete Great Dao Matrix, Meng Chuan would have no time to react. He would instantly become one with the Dao, his sense of self extinguished.
Then none of his plans beyond Dao Union could be carried out.
This was the Origin of the Great Dao, its most primordial state.
By joining with it here through the Primordial Unity Limitless Dao, Meng Chuan would experience every stage of the Great Dao's evolution.
He would pass through not only the Preliminary Prototype, but also the Great Dao Prototype outside
