The Sister of the Universal Time Travel Girl

Sister is omnipotent. My sister is incompetent. My elder sister is talented in martial arts. She can lift roof tiles when going up to a house, and kill enemies with a sword. Three steps become a poem. My sister is like Liu Fufeng. She faints when she sees blood and collapses when she sees wind. My sister knows many powerful men, and she has gained many good brothers. ============= The new book "The System: The Elder Sister Is Difficult" has been uploaded.
