My Junior Sister Cannot Be the Demon Lord of Destruction

My junior sister was raised by me. I fed her with Zuowu's milk, cooked porridge with snow water from Kunlun Mountain, and mixed cold dishes with snow lotus from Tianshan Mountain. Even the diapers I changed when I was a child were washed by myself. When she was eighteen years old, she said she wanted to visit relatives and went down the mountain, but she never came back. I went down the mountain to look for her, but I only found a body without any seven souls or six souls, only a ray of remnant soul. I picked her up again and started raising her while helping her find her soul. This road was not peaceful. Countless people came to the door and started to act fiercely, with swords and swords clashing—— "You, the devil's accomplice, take your life!" Later, treat each other with courtesy and move people with affection—— "Shangxian, you can't save her. She is a world-destroying demon. If she returns to the world, she will definitely bring about a bloody storm." I ignored it. My junior sister was raised by me. I know best what kind of person she is. She is a good and kind-hearted child who can't even bear to step on ants. * I was raised by my senior sister. But the senior sister didn't just pick me up. I also picked up a dragon, a sickly chicken, and a miscellaneous tiger. These things are really annoying the more you look at them. And these things also laughed at her, saying that she was just an ordinary mortal. Indeed, my senior sister was born to be a true immortal with magical powers, but I knew nothing and always got into trouble and asked her to clean up the mess. I don't want to live like this anymore, go down the mountain to learn skills and eventually achieve something. Although there was a slight mistake in the middle and he became the world-destroying demon king among the people, it was not a big problem. As a result, he was assassinated and almost lost his soul. Fortunately, my senior sister came to rescue me. * The heart-throb and cool fairy x the duplicitous green tea demon The low-level demon fairy, the heroine is invincible in the world Mission: Never give up hope even in adversity
