We love you! And we don't want you to sacrifice yourself for us!
I need to do this for the family!
I will kill you beast!
I am glad my people are happy again.
Chi Li's heroic trait would be her selflessness. She shows this in the beginning with her family. Chi Li wants to sacrifice herself to the dragon to eat her for money that would help her family out. But her family tries to tell her not to.
Chi Li decides to sacrifice herself anyway. So she went to the Chinese Minister to get sacrificed to the dragon. But with being sacrificed she wanted three things. A serpent dog, a sword, and the honor to use them any way possible. So she goes to see the dragon not to try to be sacrificed but also to kill the dragon.
Chi Li killed the dragon and was brought back to the village to by the soldiers. She was honored and celebrated by her people and she became their queen. With her selfless act she helped her family with the money and her people with the dragon.
