As we know that, in JY's universe, certain animals live longer than they are supposed to live.
For example, Guo Jing found his red horse when he was 17 years old. Yet, until the very end ROCH, Red horse did not die. It's roughly more than forty years of time. How long usually does a horse live. Also his White Eagles lived more than 40 years and met unfortinate end.
There are other animals like Yang Guo's undying Divine Condor and ZWJ's White gorilla which lived more than 90 years.
Are there any other animals that just don't die?
