Among the books Jiang Chen had read, many of them were myths and legends, which were all about the immortals.
The strongest practitioners, emperors or Martial Divinities, would all die and turn to dust. Only the immortals would live forever and stay young. However, no one had ever achieved that state yet.
The fate of all creatures was almost the same, regardless of strength. The eagerness to be immortal inspired people's imaginations. They imagined that among the planets, beyond the Milky Way, there was an entrance leading to the land of the immortals. Here, there was a gate called the South Heaven Gate. Walking through the gate, was located the Heavenly Palace where the immortals lived. However, this was only one of the numerous myths that could not be proved.
