Born into a wealthy family, Gu Shenwei was spoiled and carefree. However, at the age of 14, his entire family were brutally murdered, and he was caught by some bandits who sold him into slavery. As a slave boy, he entered Golden Roc Fort by chance and found the man who had slaughtered his family. He endured insults and worked hard to improve his kung fu while working as a slave boy.
