Wielding the Power of Heavenly Tribulations

Since the protagonist said that she would marry Nie Hongxiu in the future, she should be the first heroine. Why did the author write so few scenes for Nie Hongxiu? Nie Hongxiu has almost no scenes except for the few chapters where she and the protagonist snatch the marriage. Ye Qingcheng is just a person that the protagonist saves. She has more scenes than the person the protagonist wants to marry? After reading Chapter 100, almost all the scenes with the women around the protagonist were Ye Qingcheng, so they were withdrawn.
