只见 is a fixed phrase that introduces what the speaker or narrator sees, often with a sense of limitation ('only see') or sudden discovery ('to one's surprise, see'). It commonly appears in narrative contexts, especially in classical-style or literary Chinese, to shift the focus to a visual scene. Note that the standard pronunciation is zhǐ jiàn, though the dictionary lists zhī; in practice, always read it as zhǐ jiàn.
