Record of Cultivating Immortality in the Mortal World

A legend from ancient times:

Immortals stood at the pinnacle of humanity, the peak of power, and the source of the Dao.

They looked down upon the mortal world from the Celestial Palace. With a flick of their fingers, cities were destroyed and their people reduced to ash.

The immortals were merciless, treating all living things like straw dogs.

Then one day, blood-red thunder suddenly appeared in the sky.

The immortals turned pale with panic. The Celestial Palace had fallen.

The upheaval lasted three days, and the immortals' blood flowed without end for just as long.

The age of immortals ended in ancient times.

Since then, there have been no immortals in the world.

An age of cultivation belonging solely to humanity had arrived.
