After Being Electrocuted by the Historical System, I Became a Savior

I rely on wearing out my memory to leave a light in the history. Being bound by the system to correct history, Shen Yan's only wish is to lie down. Until he saw Bigan's unwillingness before his heart was cut open, and heard Wu Zixu's mournful scream as he passed Zhaoguan with his white hair. The system said: Save one person and lose ten years of life. But he lost something more precious - the memory of "himself". From then on, he became the only lampkeeper in history. The moment the light came on, he faded away. Later, all the regrets in Qing history reflected an eternal lamp and a traveler who gradually forgot his way home.
