Hand over the Time and Space Gate, the Whole Country Takes Revenge 1937!

In May 1937, Daxia was on the eve of the outbreak of the all-out war of resistance. Here, geological prospector Lin accidentally opened a space-time passage to the broken old earth. Facing that era when the poor and weak were about to suffer a baptism of blood, he did not choose to be a traitor to make profits, but turned around and handed over this "door" to the country. As a result, a national-level aid spanning time and space quietly unfolded. There is no magical invincibility here, only the sophisticated "537 Special Operations Group" strategizing behind the scenes. From penicillin to seamless steel pipes, from high-yielding grain seeds to top-secret intelligence of the Japanese, the modern industrial system has turned into a silent torrent, continuously transported to the old soil. We do not directly intervene in the war, but we vow that the martyrs will no longer charge hungry, no longer die due to lack of ammunition, and no longer die of curable minor injuries. This is a story about repairing regrets, using the industry and logistics of a great country to create a new steel backbone for that tragic history.
