826 chapters that become useless as a new story begins

What a strange story, the author put in the trash 826 chapters to start a new story in the same novel by reincarnating the hero in the body of another. Knowing that he left a woman and her family in the great ceng that was going to face a calamity 100 years later, it was not mentioned even after millions of years and the hero had to rebuild his life having had 3 or 4 women with 4 children.
It was a big disappointment while the story was interesting and although the novel is still in progress, I lost hope that he could return to great ceng and find qin ling and the others because it does not take the path.
