On the Rooftop, I Use Logic to Break the Troubled Times and Sacrifice on the Rooftop

In the last years of Dajing, mountains and rivers collapsed, natural disasters raged, and people died of hunger all over the land. In order to appease the so-called wrath of heaven, Su Qingyuan, the last legitimate princess, was pushed to a high altar by her biological father and was about to sacrifice her body to heaven. A top student in modern sociology comes through time travel, and is in a dead end at the beginning. There is no golden finger and no one comes to rescue him. Faced with the shouts of the people and the coercion of the national master, Su Qingyuan, who was covered in chains and bloodstains, exposed the illusion of heaven in public. Locust plagues originate from abandoned fields, floods originate from disrepair of rivers, and all disasters are man-made disasters. She used logic to deduce the disaster situation and used common sense to shatter feudal superstition. The predictions came true one by one, but she was denounced as a witch by the world. In troubled times, only Xie Linyuan, the former star observer, understood what she was doing. Two sober people met and stood side by side in the torrent of ignorance, destroyed the divine power, dealt with disasters, reformed the old system, and reconstructed thousands of miles of mountains and rivers based on human reason on the ruins.
