Togay performs a ritual somewhere in the forest for the Mongolian soldiers who died. Meanwhile, Camuha comes and tells that Nikola’s soldiers died in the tunnels. Togay realizes that Osman is using gunpowder and goes to talk to Nikola. Osman and his soldiers return to the plain after their victory. Everyone in the plain congratulates Osman and the Alps. Cerkutay talks to Bamsi and asks if his hand is healed. Umur is happy with the win but thinks Nikola might cause a problem. Nikola finds the commander of the soldiers who should attack through the tunnels and says he lost the war because of him.

The next day, Yason goes to Nikola’s castle and tells that the Christians in Yarhisar started to go to Osman’s plain to avoid paying heavy taxes. Nikola asks Yason to let the Christians go and tells him to put a spy among the people. Christians from Yarhisar come to the Kayi plain and say that they escaped the lord’s heavy taxes. Osman orders tents to be set up for his guests. Togay and Camuha go to Nikola’s castle. Togay says Nikola was a traitor.

Osman reminds Camuha how Genghis treated the guests. Osman says that no matter what happens, he will not return the refugees. Bamsi then tells him he has a word to say for Togay and slaps Camuha. Some Beys think that Geyhatu can attack. Osman says Togay can ally with Nikola to collect the taxes. Camuha tells Togay that Osman will not return the refugees.
