Six-year-old Lin Nuonuo was the most beloved little girl of the old Red Army grandfather who had completed the entire Long March. She cried until she fell asleep while clutching the military medal left by her great-grandfather. She unexpectedly awakened the ability to anchor time and space in her blood, and stepped into the war years of a hundred years ago. During her first time crossing, she stuffed a toffee into a little Red Army soldier with a broken leg in the trenches of the Xiangjiang River; during her second time crossing, she wrapped her down jacket around the frozen trumpet player in the snow of Jiajin Mountain. Her secret was soon discovered by the country, and the top-secret "Guiyan Project" was officially launched. Three iron lines were hung high above the base, with the words "never change the main line of history, never leak confidential information, and never interfere with the historical process." The only thing they can do is to let this child with pure eyes be a messenger in time and space spanning a hundred years. Bring a bite of soft sweet bread to the boy who was chewing tree bark on the Long March, give the militiamen in the tunnels a look at the harvest fields with rolling wheat waves, give the little carrots in the garbage cave a look at the school with the sound of books under the sun, and give the volunteer soldiers in the ice and snow of Changjin Lake a look at the brightly lit Chang'an Street. Nuo Nuo said in a sweet voice: "Grandpa said that you are fighting so that we can live a good life. Let me tell you, we are living a good life, and all your wishes have come true." This is a two-way journey that spans a hundred years. They paved the way to the prosperous age with their flesh and blood, and with the glory of the prosperous age, we give them a fulfillment that is a hundred years overdue.
