Ever since settling in the underground factory, Lu Yan had immersed himself completely in cultivation.
In two days, he broke through to the sixth level of Qi Cultivation, and five days later, he overcame the bottleneck of the Late Stage of Qi Cultivation and entered the seventh level.
Within just half a month, Lu Yan had traversed a path that most Loose Cultivators could not complete in a lifetime, successfully breaking through to the tenth level of Qi Cultivation, which is the peak of Qi Cultivation in conventional terms.
Once one steps into the tenth level of Qi Cultivation, there is an opportunity to impact the Foundation Establishment Realm; the vast majority of Loose Cultivators will try every means to acquire a Foundation Establishment Pill, hoping to break into the Foundation Establishment Realm with its aid.
However, sect disciples, in pursuit of a more perfect Foundation Establishment, will step into the eleventh level, or even the twelfth.
