[Crossover] Waiting a Thousand Years

Shanks x Long Kui When the Kingdom of Jiang fell, Long Kui leapt into the Sword-Forging Furnace with the unfinished Demon Sword in her arms, becoming its spirit. More than a thousand years passed. The top of the Demon Sealing Pagoda suddenly collapsed, and the Demon Sword emerged, only to arrive on a winter island along the Grand Line. Long Kui came out of the Demon Sword ahead of time and found the brother she had not seen in ages. But... Shanks: "What sister? I don't have a sister!!! You've definitely got the wrong person." Long Kui: "We are siblings, bound by blood. How could Long Kui be mistaken?" Later... Long Kui finally realized she really had made a mistake. Shanks truly wasn't her brother. P.S.: Different worlds, different styles, and yet they're falling in love ^(￣︶￣)^ Long Kui isn't weak, just kindhearted. But what matters most to her is her brother. Long Kui hasn't met Jing Tian yet. When she comes out of the Demon Sword, she assumes Shanks is her brother. (If that's a dealbreaker, please don't read.) I'm not a great writer, so please bear with me. Theme:
