Chen Xiaobei moved Xiao'er into the Myriad Beasts Ring.
An image of a beetle and a small but full battery appeared in Chen Xiaobei's head.
This meant that Xiao'er's health was at its optimum state. Almost instantly, Xiao'er's battery turned green, indicating that Xiao'er was cultivating and was at the peak of its current cultivation.
When Chen Xiaobei checked it earlier, Xiao'er was at the peak of Celestial Cultivation, approaching Ethereal cultivation.
So, when the full, green battery turned empty and red, it would mean that Xiao'er had broken through to Ethereal Cultivation.
