Since I Have No Sense of Existence, I Can Only Go Out for Assassination.

Dear Historical Association member (probation period) Zhang Pan, welcome to the "Revised Manual of Human History"! Because the history you originally lived in was unfortunately corrected by "errors", and the sense of existence unfortunately fell to zero, you were unfortunately lost in the original history. Since your current sense of presence is 0, the recommended method of historical correction is assassination. Now, please step onto the stage of history!
