Ruan Ning and Liu Che wiped out the dead soldiers at Ronling border, found out the opponent's dormant plot, set up Baixiaomen's spy, and returned to Yangliu Village. After returning home, Ruan Ning promoted high-yielding fruits and vegetables, built workshops, distributed cheap pills for free, and helped the abused Zhang family to work and become independent. Ruan Shu devoted himself to studying medicine and drawing, and Ruan Jun practiced martial arts with Ge Lao. Song and Ming sent news about the store in Fucheng. Ruan Ning opened Yangliu Restaurant, and the special sauce dry goods became an instant hit. Shopkeeper Zhao, who was traveling with him, poisoned the counterfeit goods, and the two caught the villain's minions on the spot. They used the reputation of the Liang family to gain a foothold and open up the business routes of the three houses.
