Heaven-Defying Sword Ancestor

One body and two souls. One soul is simple and kind; the other soul is extremely smart and ruthless. Twelve swords display their magical powers. One sword can kill immortals; two swords can kill demons; three swords can break the sky... This is my second time writing a book, so the writing style and ideas may not be enough. I hope you can give me some advice and support for newcomers. This book is a slow-burning one, but it won't be too slow. I hope you can support me a lot, spend a lot of money, and give a lot of rewards. Xiaoye is very grateful...
