And now, the way Shangguan Xiu looks, it's obvious he's going to dig up his father's grave. Chen Yao's father was also a Prince; even though their relationship wasn't particularly deep, he was still his father. Suddenly, Yao felt he couldn't accept the idea of digging up his own father's grave, and he was also afraid that once it was done, the Old King inside the Imperial Palace would find out.
Moreover, there was still his grandmother at home, but she had gone to sleep at the moment. If he went to dig up the grave and his grandmother found out, he would be in big trouble.
So, Chen Yao felt overwhelmed, because there were so many things he feared and worried about. Yet he was even more afraid of Shangguan Xiu's methods; he feared that if he refused Shangguan Xiu's proposal, Xiu might kill him.
