The acquisition of this kind of technique was completely achieved by accumulating a large number of elemental stones. For others, even if they had spiritual treasures and elemental stones, they might still have ended up empty-handed.
Only Chen Fei had the possibility of turning this impossibility into possibility, thanks to his panel.
Chen Fei's strength was constantly improving, and the consumption of elemental stones was also astonishingly high, because each time the spiritual treasure swallowed, it consumed nearly a hundred pieces of medium-grade elemental stones.
Although over ten thousand medium-grade elemental stones seemed like a lot, the time that the spiritual treasure could indulge in devouring them without restraint wouldn't be too long.
However, Chen Fei didn't mind. The ultimate goal of earning so many medium-grade elemental stones was to use them.
