1937 Time and Space Gate, I Decisively Handed over to the Country

[Double penetration + handing over to the country + heavy firepower and dimensionality reduction attack + making up for regrets + never being a virgin] Cao Gen accidentally activated the "Scroll of Mountains and Rivers", opening a space-time door to a parallel world of war and chaos. Behind the door, the sky is full of wind and snow, and the mountains and rivers are broken! The ancestors cried blood in their eyes: "If we don't have guns or cannons, I'll fill them with bones!" "I request to hand over the space-time gate to start cross-era assistance!" The "Revival Plan" was launched with a bang, and the industrial machinery of the great country was fully revived!

The individual anti-aircraft missile exploded in the air! Distant fire washes the ground beyond visual range, leaving no grass behind!
