Now, two people suddenly appeared trying to take the identity of Heir to the Throne from him. One is his own sister, and he knows this sister can't possibly compete with him, so he's just angry at Chen Menglu but doesn't hate her.
But An Xiaomian, to him, is like a stranger. Such a stranger wanting to take his heir's identity—how could Chen Yao not resent An Xiaomian?
Moreover, although it was he who ordered someone to kill An Xiaomian, which led to accidentally killing his beloved Luo Keke.
But Luo Keke died because she shielded An Xiaomian from a bullet. Chen Yao now also blames An Xiaomian for this incident.
Therefore, his beloved Luo Keke died because of An Xiaomian, and yet this An Xiaomian still wants to snatch his heir's identity. Why shouldn't he take this opportunity to kill her!
