Noble Consort Qi had used the product, and then an incident occurred. Even if it didn't ruin her face, she probably suffered at the time and it also affected her favor, which is why Noble Consort Qi had the Yu family's property confiscated and banished them.
If she had been less hot-tempered, she might have forgotten about the incident. But clearly, even after two years, Noble Consort Qi still remembered the original issue, and certainly, after the Yu family's downfall, they must have implicated Ye Muyu.
But at that time, Chu Heng had passed the imperial examination and had already gained the Emperor's favor in the capital. No one knew what method Chu Heng used to resolve the trouble created by Noble Consort Qi.
