Sign into the Divine Dynasty, and All My Heirs Will Have the Qualifications of a Great Emperor.

Li Xuan traveled through time and became an emperor of the Great Xia Dynasty who was about to die of old age, but accidentally activated the god-level sign-in system. Sign in at the palace and gain immortality! Sign in at the harem and get full charm points! As long as you keep having concubines and spreading your business, you can get massive rewards, and all your heirs will be blessed with great luck and be born to be great emperors! A few years later, when the giants of immortals and demons from all over the world arrived and prepared to carve up this mortal divine dynasty, they were horrified to discover that the farmers in the divine dynasty were masters of swordsmanship, the old man sweeping the floor was the Immortal King of Samsara, and even the big yellow dog guarding the door was a supreme demon emperor! And behind these existences, they all have a common father!
