This person was indeed Ah Ji.
Ah Ji did not ride a horse, as horses are valuable assets, and without County Captain Jiang tagging along, riding a horse on these rural trails would attract too much attention.
He did not drive a mule cart either. Instead, he changed out of his brocade robe from the daytime and donned coarse clothing. Carrying a hemp sack on his back, he disguised himself as a farmer and made his way towards Da Feng Village.
As he neared Da Feng Village, he didn't immediately enter the village. Instead, he hid in a forest with newly sprouted leaves until midnight before emerging from the forest, taking a shortcut to the Qin family residence.
Knock, knock, knock, knock~
Ah Ji knocked on the gate of the Qin family courtyard.
