Cheng Gu wanted the same for Xia Wen. Once Xia Wen lost the love of his life, he would definitely feel as much pain as Xia Zhe. Cheng Gu also wanted to take away Xia Wen's ears and eyes. He had heard that Xia Wen had extremely sharp eyesight and was said to have been very smart since he was young, even possessing a photographic memory. Cheng Gu wanted to destroy Xia Wen's eyes and ears so that he would have to live in silence and darkness for the rest of his life.
Cheng Gu was the one who shot Xia Mao in the heart a month ago. He did not expect Xia Mao to be so unafraid of dying and take the bullet for someone else. However, Xia Mao doing that was as good as helping him to fulfill his wish. He definitely did not expect Qiao Mei to be able to save Xia Mao despite the serious injuries. What an eyesore she was.
