Empress Tianhong discovered that although the Nangong Sisters often indulged with Lu Chen, the sisters were also particularly diligent when cultivating.
Empress Tianhong had originally thought that their cultivation was aimed at liberating themselves from Lu Chen one day, thus they cultivated so desperately.
Therefore, she intentionally reminded them that no matter how much they cultivated, if they did not repay their karma, once their Cultivation State reached a certain level, advancing any further would be very difficult.
If they wanted to become stronger, or achieve the status of Emperor, they would need to repay their karma.
At this moment, Empress Tianhong looked at the two women again; both of them were wrapped in heavy karma, and these threads of karma were very thick, making it difficult to either break free or repay.
