Chapter 59: The Last Spot_1
[Thirteenth minute, Lina breaks through to the Earth Immortal realm.]
To capture Wang Ran's attention and prove her competitive spirit, she successfully became the first person to break through to the Earth Immortal realm.
Following her, the other four Sages also successfully broke through, one after another.
[Simulation End]
Essentially, being a Sage isn't a complete realm in itself. In fact, ordinary beings reach their peak once they cultivate to the True God level. Advancing to Sage status is due to the lack of method to break through to Earth Immortal, hence it's further development on top of the ordinary beings' level.
Any powerhouse who becomes a Sage could easily succeed upon obtaining the method to cultivate into an Earth Immortal.
