Lu Zhiwei hasn't been in the Golden Core Stage for even five years yet.
A typical Golden Core Cultivator, relying solely on daily cultivation, would need at least ten years to advance from the First Layer to the Second Layer of the Golden Core Stage.
Achieving such results isn't due to the effects of a Cultivation Cave Mansion or a Spirit Gathering Pool.
The Cultivation Cave Mansion can increase the cultivation speed of sect members by 35%, but it only works for Crystallization Stage cultivators and below, so Lu Zhiwei's use is evidently futile.
As for the Spirit Gathering Pool, it can only be used by cultivators below the Golden Core Stage.
Once exceeding the Golden Core Stage, it has no effect.
Lu Zhiwei's progress in cultivation is entirely due to her own hard work and the effects of some elixir supplements.
Even the Illusion Tower's effects can't apply to Golden Core Cultivators.
