I Bound Myself to the World-Destroying Big Boss

I feel a little nostalgic. Back when I was a sophomore in high school, I wrote a side story. The initial protagonists were the Nanami sisters, who ultimately failed in their relationship. The reason, of course, was because I'm a siscon (sister complex). I love my sister, so I hoped the sisters could have a happy ending. The story was written as follows: Nanami Rin didn't fight the ten angels to the death, but instead relied on her superior cultivation level to escape and assassinate them one by one. In the end, the Seven Sea Gods were resurrected. In the final battle God and Rin vs. Nana and Orihime Over these years, Rin developed a fusion technique, fusing her love with the god and sublimating it into God Rin. Even Ryugu Orihime, who was about to transcend, was suppressed. Finally, Nana and Orihime's fusion is about to be broken, and then the system takes Ryugu Orihime and runs away to another world (the world of the fantasy empress, but this world is real). After Ryugu Orihime obtains the last opportunity of this world, she will also return to the original world. After obtaining the world's opportunity, Shinrin began her happy life. Rin and Orihime Ryugu meet again, but because they don't want the world to be destroyed by the aftermath of their battle, they don't fight. Instead, they live together peacefully. Moreover, over the long course of time, as the only four immortals, they forged a deep friendship. Later, they each had a daughter, Mirai and Mio. They became the main characters later on. Mirai and Mio were childhood sweethearts, but later, due to emotional conflicts, suspicion arose. Because there was no other world or opportunity for transcendence, Rin and Mirai went to the initial world of the Dragon Palace to seek that opportunity, leading to a love-hate relationship. Since the system only had one world coordinate, there was only one chance for transcendence. Despite Mio's poor mental state, Mirai ultimately prevailed, and Mio cried. If Mirai had transcended, Mio would no longer be her match. Countless years passed, and Mio gradually withered away… in Mirai's heart… I don't know how it ended.

Honestly, it's not badly written. There aren't any disgusting scenes or rambling thoughts and memories, unlike some other novels that are too long and verbose. Upon closer inspection, it's full of fluff. Overall, it's fairly concise, but the rapidly jumping chapter count is a bit alarming—1 million words and 500 chapters! #(Question mark)
