Commercial giant Tang Long lay dormant for five years and returned to the country, originally intending to celebrate his mother's birthday, but crashed into his mother suffering inhuman bullying in the Li family. The former dragon head's thunderous fury shook, sweeping across the four major families, purging group borers, and even pulling out the behind-the-scenes mastermind who murdered his father. In the process of guarding his mother, he not only made the evildoers submit to the law, but also used cutting-edge medicine to make his mother see the light again. The story shows the traditional virtue of "filial piety first of all", conveying the firm belief that "justice may arrive late, but it will never be absent".
