[Alternate History] In the first year of Taichang, undercurrents surged in the court. Suspicious clouds about Xiaoling, the secret case of Hongwan, and the old situation of Bingwu stirred up the government and the public in the palace!
The rebel party used the secret incident of Bingwu to collude with the powerful eunuchs, and used secret incense recipes to create many hidden situations and bring trouble to the court. The entire Shen family has been wronged, and the orphan Shen Qingci possesses a unique skill in incense. She hides in the market incognito, hiding her edge with a firework, and vows to find out the truth behind the family's destruction.
She meets the cold-faced powerful minister Lu Jin who is ordered to thoroughly investigate the Hongwan case and Xiaoling secrets. From testing and guarding to working side by side in life and death, the two use incense to decipher secret messages, dismantle conspiracies, uncover the inside story of Hongwan and Xiaoling, smash the Bingwu conspiracy that has been entrenched for many years, clear up the injustice for the Shen family, and clear up the turmoil in the court.
The big case is settled, but the remaining evil is hidden. Many years later, her beloved daughter Lu Chenyan inherited the original intention of Xiangdao, dug deep into the secrets left by Bingwu, eliminated the remaining parties who had slipped through the net, and completely solved the ultimate old case that spanned two generations and was hidden in the mystery of Xiang and the tomb.
