The last time Lu Ye obtained a drop of Sacred Blood in the Empyrean Sea, it was both a matter of luck and the result of his unique cultivation method.
During his cultivation, he would activate the power of his Talent Tree, making his entire location resemble a bottomless black hole, crazily devouring everything around.
That drop of Sacred Blood must have floated nearby and was drawn in as a result.
If Lu Ye hadn't used that cultivation method, he wouldn't have had the chance to obtain the Sacred Blood.
This method relies heavily on luck and also severely depletes the Talent Tree, so it's not something to be used casually.
Currently, if Lu Ye wants to find more Sacred Blood, he can only rely on luck. Of course, searching for Sacred Blood is secondary; his main interest is to explore the mysteries of the Blood River.
As for whether he will gain anything, it's hard to say.
Time passes.
