In 2045 AD, genius physicist Lin Yuan's "space-time anchor" experiment caused an accident and threw him into Nanjing in 1937. In the war-torn history, he must hide his future identity and use scientific knowledge to survive, but finds that every intervention he makes is reshaping the direction of history. Saving one person may destroy ten thousand people; standing idly by, your conscience is burning. When the past and the future are torn apart, he must find a third way through the paradox of time.
