Of course.
Actually, many Human Immortals, especially those lingering in the early to middle stages, are quite few in number when it comes to reaching the late stage and aiming for a breakthrough to become an Earth Immortal.
From this perspective, the proportion isn't really that high, perhaps four or five late-stage Human Immortals might produce one Earth Immortal.
However, those who are able to cultivate to the late stage of a Human Immortal are without exception the elite chosen from among thousands, carefully selected and nurtured seeds of various sects and factions.
These individuals are already geniuses, and it takes several geniuses for one to become an Earth Immortal.
It also indirectly illustrates the difficulty of breaking through to the Earth Immortal realm.
Given the difficulty of breaking through to become an Earth Immortal, Lu Yuan of course needed to make thorough preparations.
Now was not the time to let his Avatar attempt the breakthrough to Earth Immortal.
