Chen Yao had his reasons for not answering the phone. After all, Shangguan Quan was currently in a stupor and couldn't speak.
Grand Elder Shangguan wasn't foolish either. If he got the chance to speak with Shangguan Xiu, he would definitely give him a hint and have him come over for a rescue.
As for Chen Yao, clearly he didn't know Shangguan Quan well in the first place and had even less reason to answer his phone.
Most importantly, Chen Yao had always regarded Shangguan Xiu as his lifesaving benefactor. Now, coming to seek revenge on his benefactor's grandfather was something Shangguan Xiu would eventually learn and might not fault him for, but for now, Chen Yao didn't want Shangguan Xiu to know.
So, Chen Yao immediately hung up the phone and even switched it off.
