The long night is endless, the black rain corrodes, and the desolation corrodes everything.
He was exiled by the Chu family to a ruined town with only 370 people. The food was exhausted, the walls collapsed, and no one came to help him. He thought he would die here, until a broken jade book awakened in the sea of consciousness - it could see things that others could not see: the remaining spiritual power in the waste elixir, the patterns in the broken formations, and the hidden magical powers in the inner elixir of monsters.
From guarding a town to letting the whole city see him; from abandoning a son of the Chu family to taking the position of head of the Chu family. Every step he takes lights a lamp in the long night.
But as he walked further and further, he discovered that the secret of the jade book was much more than that. The collapse of the world thousands of years ago, the things at the bottom of the town guarded by the Long Night Guard, the man in black robes with the same face as him in the illusion... All the clues point to the same direction.
The long night will not end on its own. Unless someone lights the lamp with their own hands.
