A System, the essential golden finger in transmigration stories.
I, Yun Yi, became a savior and gained a System. Under the System's persuasion (read: sweet-talking), I set out to correct the mistakes of history and save the world.
To save the world (seriously), I resolutely became a lone savior. But for some reason, along the way to saving the world... I seem to have quite a lot of older sisters?
Damn System, did you read some unbelievable secret deep in my heart!!!
PS2: This is a serious historical novel (seriously), so serious you could use it as a thesis for a graduate history program (strikethrough). I just don't know why the male lead has so many older sisters (mischievous grin). It has absolutely nothing to do with the author's kinks! (Believe me!)
