The Source of the Curse!

Zhou Yu remembered that he had gone to visit his sister. In Zhou You's tent, Zhou Yu could not bear to tell his sister about their father's decision. He could imagine how sad Zhou You would be if she knew that their father had decided to send her to the Tail Bind Tribe as a gift to their leader.

Even if Zhou You knew about this in advance and caused a ruckus, there was no way to change the outcome. This was because Zhou You was someone the Tail Bind Tribe had specifically asked for. If someone else was sent over, the Tail Bind Tribe would most likely not be able to accept it.

After leaving Zhou You's tent, Zhou Yu ran around the periphery of the Forbidden Feather Tribe's territory to vent his frustration. In the end, he fainted in a field.
