The Tustle between two Magicians, Kankal and Kalbherav, created the story of Jantar Mantar. Kalbherav destroyed the Kingdom of Raja Virbahu and turned him into a stone. The only alive were the little Kumar and Maharani. Kalbherav conquered Jantar Mantar.
Now the only deed in his life was to get Neelampari and it was possible if someone could get the Ring from Gufa-which was protected by a Dragon and the only man who could get was the Kumar who had five moles on his hand and now was a grown up man.
Through Neelampari he came to know about his real identity. She also told him that he can turn the stones into life if he can get the water from Kanchan nadi - Kumar took the oath to kill Kalbherav. Kumar and Bulbul went in search of water-on the way they met Kankal as camel who helped them and with great difficulty they reached and came back with water and turned Kankal into his own who told them about Neelampari who was caught by Kalbherav. Kumar reached there, in fight Kalbherav flew away the Amar panchi in which he had his life.
