Xiao Shi's pupils suddenly constricted. While he was shocked, he felt enlightened. He felt that this was unexpected, but it was also reasonable. In that era, the only one who had the ability and courage to kill this prince was definitely the Martial Emperor.
Other than that, there was no other person who could do it.
Xiao Shi just could not understand why the Martial Emperor did this. Even a monster would not hurt its own children. Even if this prince did something out of line, the Martial Emperor didn't have to kill him.
Moreover, even if this prince really committed an unforgivable crime, the Martial Emperor could also choose to kill him in front of the entire world. It was not such a sneaky and obscure kill. With the Martial Emperor's strength and status on the Tianwu Continent at that time, he would definitely kill whoever he wanted. No one dared to say anything.
