The Empress’s Blind Consort: Invincible in Secret Novel

Meng Qingzhou traversed into a book and unexpectedly awakened the Blind Sword Saint System, becoming a blind sword saint. Fully aware of the book's plot, Meng Qingzhou didn't want to be a mere tool for the protagonist's face-slapping moments. So, he decided to slack off and enjoy life, spending his days gardening, walking the dog, teasing the maidservant in his leisure time, and accompanying his virtuous wife.
However, little did he know:
He lived in a grand palace, the coquettish maidservant was a cold and beautiful sword fairy, the flowers he tended were millennium-old divine herbs, the dog he walked was a national guardian beast, and his virtuous wife was the current Empress!
The Empress went to great lengths to have everyone act in front of Meng Qingzhou, portraying an ordinary family, just so she could have a place of peace during her spare time. But unexpectedly, not only did she hide her identity, Meng Qingzhou also concealed his sword saint prowess!
Rebellious vassal kings: "Dongfang Liuli, you are infatuated with Meng Qingzhou's charm, neglecting state affairs, you should be punished!"
Meng Qingzhou: "Nonsense, being infatuated with my charm is my wife's official business!"
Enemy envoys: "Either cede land and pay reparations, or face the destruction of your country and family!"
Meng Qingzhou: "I only have a small plot of land, and you still want to take it? Sword, come forth!"
When the allied nations conspired to hinder the Empress's path to unification, Meng Qingzhou rushed to the border alone, unsealing his eyes. At the moment he opened his eyes, the sword saint emerged spectacularly!
Meng Qingzhou: "Is the small plot of land in front of my house really that attractive? Why do all the gods and demons come to fight over it?"
