The clone of Jiang Yuebai, who was supposed to be teaching, is currently with her main body at the abode of Cicada Spirit True Monarch, who practices the Yin Yang Family's path.
The real issue is that the 'Nine Netherworld Gate' of the Yin Vein within the Yin Yang Family is too difficult to open, so Jiang Yuebai had to call upon a clone to join her in cultivation, doubling her efficiency.
As for the teaching side, there's absolutely nothing to worry about since she has already applied for a ten-year usage of that bamboo grove from the Inner Affairs Hall.
The runes in the array and the artifact refining challenges change every ten days. The materials used for the rewards are provided by the Zhuge Family, classified as teaching supplies, and she can produce a three-month supply in just one night.
In this way, the clone dedicated to teaching can be set free to do other things in the short term.
