Sign-In at the Divine Dynasty: My Children All Have the Potential to Become Emperors

Li Xuan transmigrated as the Grand Emperor of the Great Xia Divine Dynasty, an old man on the verge of death, but unexpectedly activated the Divine Sign-In System. Sign in at the imperial palace to gain an immortal body! Sign in in the harem to gain maximum charm! As long as he keeps taking concubines and having children, he’ll receive a vast array of rewards. Every one of his descendants will be blessed with incredible fortune and born with the potential to become a Great Emperor! Years later, when the immortal and demon overlords of the Myriad Worlds descend, ready to carve up this mortal dynasty, they discover to their horror that the farmer working the fields is a supreme master of the sword, the old man sweeping the floor is an Immortal King of reincarnation, and even the big yellow dog guarding the gate is an unparalleled Demon Emperor! And every one of these beings has the same father!
