I Am the Empress

I lost my father and mother when I was young! I don't know if it's a dream or reality, but a box: two books and an unknown technique! When you open your eyes, you become a beggar! Kill a barbarian slave and become a barbarian slave princess? The leader of the barbarian slaves is dead and his sons and daughters are fighting over each other. How can Wan Ling'er win? Is the heavy helmet the secret team of the Central Plains Dynasty? Why was the father in the dream killed by the Hidden Dragon Guard?
