Li Caihong Gets The Evidence

The maid that had been sent to the brothel by Li Caihong came back after a Shichen.

Li Caihong was very happy when she came to know that the maid was successful in bringing whatever she had asked her to bring from the brothel.

There was mainly one brothel in the Imperial City that was famous by the name of the red district. 

Li Caihong remembered very well that four years ago when her sister had sent her maidservant to bring the aphrodisiacs then the maidservant had brought it from there only.

The main thing however in all this was that the maid had to give someone's name to buy the aphrodisiacs and she had given her sister's name.

Hence, the document of purchase of aphrodisiacs from the brothel has Li Na's name on it. 

Not only this, even this time during the Mid Autumn Festival Banquet, Li Na had brought the aphrodisiacs from the red district only.
