The Fifth Prince? Prince Shou, Yang Lin?
Shen Hao certainly wouldn't forget this Fifth Son of the Emperor, someone he'd had a grudge with.
Back when Prince Shou came to Fengri City, Shen Hao had volunteered to help with the city garrison. Then Prince Shou, in front of Wu Changhe—the then Xuanqing Guard Thousand Households—and Xie Youlin, the Local Government Office's Chief Officer in Fengri City, openly tried to recruit Shen Hao, even showed off some spirit stones in an attempt to bribe him. But after Shen Hao refused, Prince Shou got rather annoyed.
But even if Prince Shou was annoyed with Shen Hao, would he take such a huge risk just for revenge? That hardly adds up.
Even if Prince Shou is petty and vindictive, so much time has already passed. Wu Changhe's already turned to dust and bones, and only now Prince Shou suddenly wants to kill Shen Hao? Seems highly unlikely.
