Chen Mo, an archives employee from 2023, accidentally traveled to Northeast China in 1931 with a mysterious smart watch, which coincided with the outbreak of the September 18th Incident. He originally wanted to rely on modern knowledge to save his life, but he was accidentally involved in the dark whirlpool of the Japanese army's biochemical experiments, and became life and death comrades with anti-Japanese scribe Shen Qing, young Zhao Xiaohu and others.
The system on the wrist can exchange for guns and ammunition, but it needs to be paid with "war merits" - every bullet must be exchanged for the blood of the invaders. From the cliff blasting in Wild Wolf Valley, to the life-and-death breakout in Beiping Hutong, from the pursuit and escape by the Huangpu River, to the shock of the poisonous fog in Purple Mountain, Chen Mo headed south with the Japanese evidence in the iron box.
He has seen students singing the national anthem out of tune and rushing towards spies, doctors holding experimental records and dying on the operating table, and blacksmiths smashing Japanese helmets with hammers... These names, which only have a few strokes in the history books, have become sparks in a prairie fire before his eyes.
When the system prompted "Do you want to return to the original time and space?", Chen Mo looked at the blood-stained half of the photo in his arms, looked at the scarred but bright-eyed companion beside him, and pressed "No".
This is not an easy journey, but a history that is continued with life. He will carry those unrecorded sacrifices and those names that should not be forgotten, from the frozen soil of Northeast China to the cave dwellings of Yan'an, so that every cry in the beacon fire will be heard in the future.
