Lu Xuan was the ruler of an era without saints.
Everyone acknowledged this fact. Even the dumbest and slowest people could tell that both the Blessed Enclave and Earth would have an extremely powerful ruler for a long time.
Lu Xuan was so young; this was the beginning of everything for him.
People at the Divine Transformation Realm would live for at least 500 years, which meant that Lu Xuan could easily rule for over 400 years. Furthermore, in the coming golden age, it became obvious that the Divine Transformation Realm would not be the end of one's journey at cultivation.
According to the records and texts throughout history, one's lifespan could reach up to 1000 years if one made a breakthrough into the next realm.
That meant the world would be under his rule for at least up to 1000 years in the future, entering a long era without saints.
