This special Condor is the one that helps Yang Guo.
When he lost one of his arms (after it got sliced off by Guo Fu), it helped him kill snakes and then taking this pearl from the snake, Yang Guo ended up turning much stronger. He could carry an enormously heavy sword that was 80kg. Yang Guo ended up thanking the Divine Condor, promising to return but left him afterwards to find Xiao Long nu.
Divine Condor also helped another man who had the sword Yang Guo later finds. That man was very lonely, and he saved that man from death when he almost fell to his death after being pushed by his love-interest.
