Lin Xuan transmigrated into the primordial world and became a little demon at the foot of Kunlun Mountain. He had no peerless talent, no powerful backers, and only a useless sign-in System. While others cultivated immortality through hard work, he did it by checking in. He thought he would spend his life coasting along until he died, but after signing in for ten thousand years, he received rewards beyond measure. Patriarch Hongjun is preaching? Sorry, I just signed in and got Primordial Violet Qi. The Demon Court is recruiting? Pardon me, I got Pangu’s blood essence by signing in at the site of the War of the Liches. What? Even the Saints want me as their disciple? Too late. I still have three Saint Trial Cards left in my sign-in System! When the great calamity descended and the gods trembled, Lin Xuan quietly opened his sign-in panel. “Congratulations, Host. After signing in for thirty thousand years, you have obtained the complete authority of the Heavenly Dao.” From then on, a legend arose in the primordial world: Don’t mess with that lazy guy who signs in every day.
