In an archaeological accident in the old city, Jiang Zhaozhou was bound to the "Reverse Time Monument" system and gained the ability to return to key nodes in history. He cannot create miracles out of thin air. He can only enter major moments such as Qin's unification of the six countries, the Nanjing Massacre, the Tangshan Earthquake, and the Wenchuan Earthquake with limited knowledge, limited supplies, and trust that is on the verge of collapse again and again, striving for more ways to survive between wars, disasters, and people's hearts. Every rescue will rewrite the original timeline, and will also allow future generations to retain "dual memories": they remember the sufferings of the past, and they also remember that there were people who went against the current.
