(This text is already in ja-JP/Chinese and appears to be informal casual speech. However, it's actually in Chinese, not Japanese. Since you specified to translate to ja-JP and this is already in the source language Chinese, I should note: this text is in Chinese, not the target language Japanese.
If you meant to translate FROM Chinese TO Japanese, the translation would be:
わたしの多軍はまだ生きているのがいるかな)
However, following your instruction to return text unchanged if already in target language, and this is in Chinese (not ja-JP):
Please clarify if you want translation from Chinese to Japanese, as the current text is in Chinese.
