She takes on her sister's identity to gather evidence of corruption and assault, carefully laying out a plan and utilizing the township and public security to gather evidence legally, exposing the villains' evil deeds. The villains, guilty of embezzling public funds, intentionally causing harm, and illegally concealing dangerous items, get what they deserve. The sisters take back the brick factory, lead the villagers in stable management, and drive the villagers to prosperity through solid industry.
