The Natal Flying Sword That Was Reincarnated as a Junior Sister

My junior sister is the best swordsman in the world. And me. It is the best sword in the world. —— Below is the original introduction. Traveling through the world of immortality, Jiang Xuan devoted himself to seeking the Tao, just to achieve it and ascend to heaven. Enter the immortal gate and gain eternal life. He never expected that his ascension would be his greatest calamity. Unfortunately, Jiang Xuan died in the Immortal Sect, and passed into the flying sword of his junior sister, living a second life. Only then did he realize that the junior sister who had obeyed him in the past had already had her inner emotions distorted after his death... "Senior brother, don't you think you can escape this time?" Not only that, after discovering his traces. The originally aloof Master Wangqing Palace, the mature and beautiful Master, the cold and arrogant Saint... Also came to visit one after another. "Wait a minute, did I really come to you just to discuss the art of swordsmanship?" "What do you mean you have to discuss the art of swordsmanship with me for the rest of your life? One less day will not count as a lifetime!?" "I'm just a sword. I can't be your toy, lover, enemy, or senior brother at the same time. Please wake up!"
