Gu An fumbled around the lifespan barrier at the original spot, eventually expanding the barrier to cover an area equivalent to that of the Nine Spirit Continent.
He called up his attribute panel and invested one hundred billion years of lifespan into his physique.
Using four hundred billion years of lifespan, the Primordial Reincarnation Undying Body upgraded to the Primordial Dao Creation Body, but even a thousand billion years wouldn't be enough for the next advancement.
This time, he didn't plan to enhance himself comprehensively but instead focused entirely on his cultivation level. The reason for upgrading his physique was to observe how quickly the lifespan barrier now consumed lifespan.
Numerous prompts quickly appeared before his eyes.
The one hundred billion years of lifespan did not upgrade his physique.
Since he already invested in it, he had to succeed.
Gu An continued to invest lifespan, putting in increments of one hundred billion years each time.
