The Lightning Immortal was called Nangong Chu, and he was born in the Elixir Mansion's Nangong Immortal Race in the Virtual Jade Heaven.
The position of Lightning Immortal originally belonged to an elder of the Nangong Immortal Race. Later on, due to Nangong Chu's talent in cultivating the lightning technique, he obtained a fragment of the Lightning Immortal position by chance. Therefore, he became one of the new 8,000 Lightning Immortals after the elder retired.
Other than the Immortal Lord of Justice, the other immortal positions had a term.
Every ten thousand years, it would change.
However, the change that happened once every ten thousand years was meaningless to the immortals. It was because it was "hereditary," no matter how it changed.
