Now that she has come to this era, she will follow its rules. Feng Ye is careful to keep her identity hidden, but her abilities don't seem to allow her to stay inconspicuous. After she single-handedly stopped a barrage of fire powerful enough to destroy an asteroid, a bystander asked how she had done it. Feng Ye replied, "With magic."
