The Superpower Killer Concubine

She is not cruel, but she has no compassion. She is not vicious, but extremely ruthless. As the top supernatural killer of the 21st century, she has only one rule in life: she can lose everything, but she can never lose her heart. The only mercy he had, but it laid the foundation for his own disaster. Once she traveled through time, she became the useless princess of the Li Kingdom in the Sky Continent. The emperor didn't love her, and her mother-in-law hated her for bringing shame on herself. The brothers and sisters were humiliated at will, and she was a shame to the entire Li country. When the useless princess woke up again, she had become the cold killer. So what if I can't practice? She has incredible powers! So what if we can't conclude an animal contract? She has strong willpower, enough to make all beasts surrender! So what if she's not beautiful? Her goal is the world, not to compete with you! I don't kill without reason, I don't sympathize without reason. If someone offends me, I will pay back tenfold! These are her three tenets in life. When the waste is no longer cowardly, when she shocks the world, the world is destined to change for her!
