In Order to Protect Me, My Sister Tortured and Killed the Prince in Court

I am Shen Mo, who traveled through time and became a magic sword, and I also have a younger sister. I heard that people in this world are trying their best to kill me. I'm a little panicked now. In order to protect me, she seemed to be killing the prince in front of the emperor and all the civil and military officials. I want to ask, what should I do if I am protected by my sister one day? She seems to be sweet and cool... … My name is Shen Qiuyue. For the sake of the dynasty, brother Shen Mo used his body to become a demon to forge a sword. He single-handedly destroyed the demon lords in the ten directions and prevented mankind from destroying the country. But he has also lost all his five emotions and six desires, and will not be a human being in the next life. Unexpectedly, the dynasty was afraid that his brother would be reborn from the magic sword and that if no one could restrain him, he would seize the imperial power. So I fled with the magic sword. Fortunately, Brother Shen Mo was so powerful that I could be reborn infinitely. "It doesn't matter if you can be with Brother Shen Mo and I accompany you to become a demon." "The people of the world cannot tolerate us, then let Brother Shen Mo wake up and kill everyone in the world!" "Brother, Qiuyue finally hugs you again. Let us be the only one in this world. There will be no more rumors." This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
