Introduction: Since the Opium War, our people have been deeply squeezed and exploited by foreign invaders. This has become more serious since the Sino-Japanese War of 1894-1894. A mere Japanese island actually occupied our land, killed our compatriots, and robbed our resources. Faced with such banditry, we are helpless. In such a situation, warlords are still fighting in the country, disturbing the people and giving the invaders an opportunity. Thinking about the September 18th Incident, 300,000 Northeastern troops retreated into the pass without firing a shot, and millions of kilometers of land in the three Northeastern provinces were lost. As a time-traveling young marshal, I will lead a million-strong army to fight the Japanese invaders to the end.
