I trade away my memories to leave a light burning in the pages of history.
Bound by the System to correct history, Shen Yan has just one wish: to lie flat.
Until he sees Bi Gan's defiance before his heart is cut out, and hears Wu Zixu's anguished cry as he passes through Zhaoguan with his hair turned white.
The System says: Save one person, lose ten years of your life.
But Shen Yan sacrifices something even more precious: his memories of “himself.”
From then on, he becomes the sole keeper of the lamp along the river of history.
With every moment the lamp shines, he fades a little more.
Later, at every place in the histories where regret lingers, a light that never goes out can be seen, along with a traveler who is slowly forgetting the way home.
