At this age, for a girl in the mortal world, she would be considered quite old.
But for an immortal cultivator, she's very young, tender even, barely different from a one or two-year-old baby.
Although they seemed very young in the eyes of others, their appearances had undergone earth-shaking changes.
Their beautiful faces shed their former childishness, becoming more enchanting and attractive.
Their statures had also grown considerably, no longer to be mistaken for children.
Even the parts that should protrude or curve were unmistakably defined.
Looking at their graceful figures, they appeared just like eighteen-year-old girls—beautiful, youthful, and radiant.
And such appearance could be maintained for hundreds of years without change.
After all, the higher one cultivated, the slower the changes in appearance became.
But both Mo Chen and Bai Xuan had not noticed the girls' changes.
Since they saw them every day, they simply could not perceive any changes.
