After the Second Prince died, he left behind a confession edict and a letter. Qi Haoran took a look and asked someone to search the campsite. Only then did he confirm that all of the Second Prince's trusted aides had left.
"General, give me 500 cavalry. I will definitely be able to chase them back."
Qi Haoran waved his hand and said, "There's no need to chase after them. Just let them go. Keep the news under wraps and don't let outsiders know that Minister Qin and the Second Prince have committed suicide for the time being." With that, he put away the letter and edict.
Once the Second Prince died, the remaining areas of Chengdu Prefecture would be easy to recover. Qi Haoran only brought the army to the city gate, and the county officials inside would open the door to welcome them in.
After he walked through the remaining counties and left behind the soldiers guarding them, he brought the remaining army back to the court.
