What would happen to an ordinary person going back to the past? The correct answer is: he will die. Because there is no household registration book and temporary residence permit, hahahahahaha. But this is a novel and we return to Japan in the Warring States Period, so it is different. Look An ordinary person circled among the famous generals of the Warring States Period in Japan, Oda Nobunaga, Toyotomi Hideyoshi, Tokugawa Ieyasu, Takeda Shingen, Uesugi Kenshin... How much will history change?? )
