An emperor in his later years is summoned by his sister to save the nation's fate.

[National survival + live broadcast + bizarre invasion + aging emperor]
Lu Li transmigrates to the Xuan Tian Realm, vying for the Emperor's Path, and becomes the Eternal Night Demon Emperor.
Ten thousand years later, the world was silent, the old friends had all passed away, and he had entered his old age.
On this day, he heard the call from his blood relative, his younger sister Lu Xueyao, from Blue Star.
……
In the Dragon Kingdom, during the Awakening Ceremony of Bureau 749, Lu Xueyao summoned the projection of her brother Lu Li, making him her destined pet.
On this day, the national destiny game arrives, and each country randomly selects two chosen ones to enter a bizarre world to survive.
By establishing territory in the supernatural world, one can resist the invasion of the supernatural source into the real world.
If a player dies, their nation's fortune will be deducted, resulting in a penalty. Resources earned by the player in the national fortune game will have a chance to be returned to their nation as a bonus.
While the other chosen ones were starving and freezing, struggling to survive against the supernatural.
Under her brother's guidance, Lu Xueyao has established an unparalleled demon kingdom in the bizarre world, where all monsters bow down and all directions pay homage.
