These "sword pills" appear to be solid, but they are actually still viscous liquid.
This is the wonder of top-notch cultivation techniques, making the liquid mana develop a tendency to solidify during the Foundation Establishment phase.
Thus, it saves a great deal of effort during Core Formation.
Not to mention, the "Great Freedom Mysterious Gold Sword Scripture" allows for a Perfect Foundation Establishment mana limit of three hundred and sixty-five drops, exceptionally powerful.
It was for this reason that Fang Xing could sense the opportunity for Core Formation just after achieving Perfect Foundation Establishment.
If it were a cultivator practicing ordinary techniques who had achieved Perfect Foundation Establishment, they might still need a Core Formation Spirit Item to initiate their own Core Formation process, starting off at a disadvantage.
Boom!
After the last drop of liquid mana merged in, a white-gold Dan Pill appeared suddenly at the center of Fang Xing's dantian.
