Although with Hong Jun's status, it's unlikely he'd fuss with the small fry like the Longevity World, but in a nest overturned, no eggs remain intact.
Ji Changsheng felt a warm surge in his heart: "Mom, you're still the best to me."
"It's not given to you for free." Empress Nuwa rolled her eyes at Ji Changsheng: "When you become a Saint, let the Map of Mountains and Rivers shine a bit, try to upgrade the world inside the map. Also, stuff more worlds in it, and put more beings in it. Only with enough civilizations clashing can a more exciting world be born."
Empress Nuwa herself was too lazy to handle such a task.
She could only delegate it to Ji Changsheng.
The Heavenly Emperor of Filial had an unavoidable duty.
"Mom, don't worry, I will try to develop the Great World of Mountains and Rivers into a world as grand as the Primordial Immortal Realm, and thus expand into the Nuwa Universe."
"Then I'll really light high incense as thanks."
