We Hand Over a Time Gate, and the Whole Nation Takes Revenge in 1937!

May 1937, Great Xia. The full-scale War of Resistance is about to break out.

Lin, a geological surveyor, unexpectedly discovers a time-space passage to a shattered former homeland.

Facing an era of poverty and weakness, on the verge of being baptized in blood and fire, he chooses not to profit by smuggling goods between the two worlds. Instead, he turns around and hands this “door” over to the state.

And so, a state-level aid operation spanning time and space quietly begins.

There are no superhuman lone warriors like in war dramas, only the precise 537 Special Operations Group, making plans behind the scenes.

From penicillin to seamless steel pipes, from high-yield crop seeds to the enemy's top-secret intelligence, the modern industrial system becomes a silent, mighty current, flowing without cease into the old homeland.

We will not intervene directly in the war, but we swear that our martyrs will no longer charge into battle on empty stomachs, die for lack of ammunition, or succumb to minor wounds that could have been treated.

This is a story about mending regrets, using the industry and logistics of a great power to forge a new backbone of steel for that tragic chapter of history.
