The story began when Kamandanu, a blacksmith's second son, was interested to an old sage, Ranubhaya who was an expert in martial arts.
The story became more complex when Ranubhaya, which had survived from his house destruction, was kidnapped by Kubilai Khan's envoy who were amazed by his expertise in weaponry.
Before his death, he asked a warrior couple, Lo Si Shan and Mei Ling, to bring the sword to Che Po (Java Island, pronounced in old-china language) and give it to Kamandanu.
After being beaten and humiliated by his own brother in front of his wife and his son, he studied martial-art and became a scary warrior, called as Penyair Berdarah (Bleeding Poet).
After beaten by Kamandanu for the second time, he disappeared and forgotten until his daughter found him as a pitiful helpless blind old man.
