Zhang Yu knew that in ancient times... the Primordial Spirit of a Divinity Transformation Cultivator was both a powerful weapon and a weakness with many limitations. A collapse or pollution of the Primordial Spirit could lead to severe injury or even death for the cultivator.
However, after generations of updates by the masters and experts of Kunxu, especially the restructuring by the Ten Great Sects, the current Primordial Spirit is incomparable to that of the past.
Like collapsing and regrouping, this is the first thing today's Primordial Spirit learns after being refined successfully.
The second effect of the Ultimate-Divinity Transformation Body is that it allows Zhang Yu's Primordial Spirit to reassemble at a faster speed and with less mana consumption, giving his Primordial Spirit greater resilience.
Zhang Yu knew this was naturally a good thing, allowing his Primordial Spirit to withstand greater pressure and more tasks in the future.
