Lu Di Jian Xian

Zu An is your typical flame-war keyboard warrior. But then he was transmigrated into a world of cultivation, where political power is tied to the cultivation level of the temples and dojos. The Emperor of the Dazhou Kingdom is himself one of the most powerful cultivators in the world. Zu An migrated into the body of the despised husband of the princess Chu Chuyan. His reputation was irrevocably ruined when he was found sleeping with his wife's sister on his wedding night. But actually his whole marriage was part of a conspiracy, and the seemingly irrelevant son-in-law was the key piece in the imperial intrigue. See how Zu An will navigate the dangers and come out ahead, with the help of his keyboard!
