Yu Chuangshi, the grandson of Shanghai's richest man Yu Foying, killed his cousin's lover (his rival) after getting drunk following a breakup. This was all witnessed by Shen Zijun. Shen Zijun's brother works in the police station. In order to please Yu Foying, he hinted that Shen Zijun should change her testimony to help Yu Chuangshi escape responsibility. However, Shen Zijun refused resolutely. Upon hearing this, Yu Chuangshi became extremely angry and thus began a feud with Shen Zijun. Yu Foying then had his eldest son-in-law escort Yu Chuangshi out of Shanghai to avoid the spotlight. During the journey, the group was ambushed and the eldest son-in-law became a casualty in this dispute and grudge.
