Xie Yunqian is a third-year graduate student in the history department of a prestigious university. His research direction is the status of women in ancient times. In his paper, he conceived a female-dominated society and analyzed in detail how men of different origins should survive. In order to meet the deadline, he stayed up several nights in a row, closing and opening his eyes - immersed in his thesis. What's even more fatal is that he became the lowest-class male set in the paper: no background, no money, and could be run over at any time. Fortunately, he quickly clarified the situation. In this world, he is also called Xie Yunqian, a commoner from a small border town. With his face and excellent qualities, he made it through the draft. He was chosen by the Crown Princess Xiao Yuehua, and tonight he will enter the East Palace as a side king. According to the setting of his thesis, this is the most reliable wealth script - from now on, you can win without worrying about food and drink. Just as he breathed a sigh of relief, the bridal chamber door opened. The person who walked in was not Xiao Yuehua, but Xiao Yuening, the fifth daughter of the emperor who was the least favored and was the first to be executed after Xiao Yuehua ascended the throne. And he, inexplicably, became the official husband of the five princesses who would be executed together. There must be a mistake somewhere, why is this completely different from the script he wrote? Must escape. He must return to the Crown Princess. I'm sorry, Xiao Yuening, just die alone. But after a while - he smelled so good. He fell in love with Xiao Yuening. It doesn't matter, he is a graduate student, can he still play with the world he conceived with his own hands? Those dilemmas that he wrote with his own hands, he will now rewrite with his own hands. He wanted to help his wife change her fate against the will of heaven, defeat the four imperial sisters, drive back the barbarians in the northern kingdom, and step onto the throne of God.

Traveling through a different world, Lynch became a teenager unblocking sewers in a prison. Others use "Xuesi Bi" to control the wind and rain, but he can only contend with the water pipe that has been blocked for seven days. But when he stared at the water pipes and the water conservancy engineering knowledge in his mind was running wildly-- The water pipe burst! The sewage was like a precision-guided artillery shell, confusing the prison guard's face! Since then, Lynch has awakened the most hard-core "superpower". Controlling water is an art for others, but controlling water for him is science! Manning's formula and Bernoulli's equation are all his combat skills.

When enemies with blood mithril swarm in, when the teacher's hatred and the dark side of the world are revealed one by one, Lin Qi looked at the golden Xuesi pen in his hand and asked the "system" for the first time: "Are you really the system? Or... Are you a living person?" History is a lie written by anyone, and the truth is an obsession soaked in blood. When the dragon slayer finally becomes an evil dragon, who can write and seal this out-of-control chess game? "Lynch, your pen is not for unclogging water pipes." "It's for-" "Reshaping the rules of this world."
