The ending of Taoist novels

The writer is Zhou Dedong. Other problems are difficult to explain. I extract some other people's views: to explain this ending, we must first understand the concept of "parallel world", that is, the world that exists in different dimensions in the same process. Let's divide the two worlds into 1 and No.2. In the world of 1, Lou Xiao Lou experienced the tragedy that Sang Ya was killed by lightning. He wanted to turn the wheel of destiny through his own efforts, so in the second world, influenced by Xiao Lou, the building from 1 world, Sang Ya's life in the second world changed, but due to fate, Sang Ya finally died, so Xiao Lou, the building of the second world, went to 1 world and became a hermit, which influenced people and things in 1 world. It won't matter, but Lou Xiao Lou has infiltrated into the two-dimensional world through magic, hoping to bring his lover back to life through his own efforts. In the end, Lou Xiao Lou seems to have saved Sang Ya, but he didn't save Sang Ya either. Sang Ya still died according to her fate, which can be known when he used magic to tell her fortune, but in the end, Sang Ya didn't die. Personally, I think Lou Xiao Lou has actually become Sang Ya's father, which can be seen from the previous "daughter was her father's lover in a previous life". Three old people represent life and death and XX (the tea delivery person hasn't decided yet). Three old people come out of Sang Ya's body to symbolize that Sang Ya has been reborn, but Sang Ya is still Sang Ya. How can she be reborn without violating her own destiny? I can only go back to the past and let the two of them continue their love in another way .. Three old people represent that mysterious power. They left Sonia's body, indicating that in this world, Sonia was saved by Lou Xiao Lou from the future. In another parallel world, Sonia was struck by lightning and died. So Lou Xiao Lou set out for the world mentioned above to save Sang Ya. . .
