In this city divided by "Source Crystal" and supernatural powers, every gift has a price tag.
When others burned their lives or wealth, the price Lin Ye paid for using his powers was the memory related to his sister.
In order to save his only relative in the world, he was forced to walk in the abyss, struggling to survive among the chess game between the government, rebels and capital. Until he discovered that his "causal interference" power fueled by memory was actually the final key to opening the "door" to the destruction of the world.
When the last memory about her began to blur, Lin Ye faced the ultimate choice:
It is to close this door and become a ruthless savior;
Or will he personally start a new era in which she is destined to be forgotten?
