"The area preserved after activating [Huanzhen] is not something that will always exist. Looking at it now, its duration has been quite short."
Li Fan now fully understood the new changes that occurred on [Huanzhen] when he ascended to Unity-Path, or rather, when he accomplished Half-Immortal status.
It is that after activating [Huanzhen], not everything in the world immediately becomes illusionary. Instead, a large area is preserved in a black-and-white static state, centered on Li Fan.
As for the size of this area, Li Fan didn't have the chance to verify this time. But it must be exceedingly vast, at the very least encompassing the entire Xuanhuang Immortal Domain as far as Li Fan's eyes could see.
Li Fan also speculated that the effective range and duration of the black-and-white static area were likely positively correlated with his own strength.
Since he had only just entered the Immortal realm, the effects he could maintain were naturally extremely limited.
