Everything is purely fictional, without any adverse effects. The background of the story is a parallel time and space. There is no disrespect for history, no smearing of historical figures, and no whitewashing of the invaders. There is no system, respect for history, and restore those difficult years as much as possible. The Japanese have no IQ weakening, and the combat effectiveness is completely consistent with historical facts. There is no downplaying of atrocities. The settings are all in line with the national conditions at that time.

By flapping his wings again and again, he stirred up a huge storm in the historical torrent of this parallel time and space. From Nanjing to Xuzhou to the North China Plain, the flames of revenge from the Chinese nation were about to burn through everything in this parallel time and space.
