I Am a Guilty Person

[System, multiple female protagonists, no forced intelligence reduction, all members' IQs are online] My name is Yun Heng, a college graduate who just finished the college entrance examination, and then I was penetrated by a lunatic who looked like me, and I was transported into this world of "sin". It's so tiring. Hundreds of years ago, countless "alien" fell from the sky for no reason. The surviving humans built a nine-story tower "Nine Heavens" The male protagonist Yun Heng obtained the system "Seven Sins" after traveling through time. He is a guilty person, and he will move forward with the goal of finding the "Seven Sins" on the way to search. He went through "hell", he gained a testimony, dependence. He passed through "purgatory", he gained parting and death. He finally went to "heaven" and found that the world was sick, both for them and for himself. Yun Heng decided to "save" this "sick world" "I'm a sinful man and I don't know if I'm doing the right thing, but I see people's sin and I'm going to save them."
