Return to 1937: Beginning with the Ningcheng Massacre

[Double-passing door + fighting to save the country + surrendering to the country + passionate protection + making up for regrets] In 2037, newly retired special forces soldier Lin Weiguo touched his fingertips on the memorial wall with the name of his great-grandfather Lin Shouyi who died for his country, and his eyes turned red. This martyr who died in the battle to defend Ningcheng, together with the innocent souls of tens of thousands of compatriots, is a pain engraved in the blood of the nation. Suddenly there was a beam of light, and Lin Weiguo physically traveled to Ningcheng on December 12, 1937 - only 24 hours were left before the tragic massacre! People were displaced among the ruins of the city, Japanese artillery fire roared outside the city, and despair hit our faces. In grief, he awakened the [National War Redemption System], and his mission was to protect his compatriots and support the war of resistance. Knowing that his personal power is limited, Lin Weiguo immediately traveled back to 2037 and went straight to the theater headquarters: "Chief! A time and space gate connecting Ningcheng in 1937 was discovered. Our compatriots are in danger. Please organize support!" The news spread, and China was moved. After rigorous deployment, the highest order was issued: "Do all we can to support the Anti-Japanese War, protect the lives of our compatriots, and prevent historical tragedies from happening again!" Modern rescue forces crossed over with strategic supplies and fought side by side with the anti-Japanese martyrs: when the Japanese army approached the refugee area, they used precise tactics to build a defense line; when enemy planes attempted to bomb, they collaborated with the defenders to smash the air raid plot; in the face of the arrogant clamor of the invaders, they used their blood and faith to build a strong barrier. Lin Weiguo clenched his steel gun and charged side by side with the martyrs: "In this life, we come with the expectations of our ancestors. We will protect the mountains and rivers, comfort our compatriots in distress, and make the invaders pay the price they deserve!"
