Niccolo and Maffeo now at Kublai Khan´s court he is intriged by Christianity. If he converts then the Mongol empire will be their allies. So Kublai says to bring 100 scholars to tell him about the religion. He gives them a golden tablet for good will.
The Polo brothers are back in Venice and Marco is glad to see his father again.
The Polo's go to the pope because only he can choose 100 scholars. They soon find that during the time that they were gone the pope died and the community had not found a new one. So they gather gifts, a lamp and write a note to Kublai explaining the problem.
With that the Polo's leave with Marco and he writes about everything that he sees.
Kublai understands the situation and is not upset. He is pleased with the gifts and allows for them to stay.
Kublai needs info of the other cities in his empire but cannot travel himself. So he thinks of Marco's passion and writing skills
