Su Tang always thought she was an ordinary person until Lin Xue personally cut out her life and threw her into an underground blood pool as a life-extending blood bag. When the blood flow was about to end, countless fragments of doomsday flooded into his mind - she was the real master of doomsday, and what Lin Xue stole was just the residue.

But when everyone thought victory was in sight, Zhou Shen activated a deeper doomsday gear, and Su Tang had to make a choice between complete darkness and saving the world.
