Huaxia Civilization Helps Me Save the Earth

Earth's cultural heritage has been severed, and all the splendor of five thousand years of Chinese civilization has been lost. The Alliance has decided to abandon Earth and lead humanity to flee, becoming a subordinate second-rate species on another planet. Muruman and other Chinese leaders firmly opposed the plan, but the Alliance retaliated with sanctions: If you don't want to leave, then the people of China will go to the front lines to fight the monsters, and be the last to evacuate! With a great war on the verge of breaking out, Muruman, now a pawn abandoned by the Alliance, suddenly regained her memories. It turned out she wasn't a native of this world at all. She was a person from China on another plane, accidentally sent here! Qin Shi Huang: I united the six kingdoms and brought all under heaven into one. I built the Great Wall to protect the dragon veins of the nine provinces, defend my Great Qin, and safeguard my state. In the name of the First Emperor, I make this vow! Emperor Wu of Han: We must ensure that the barbarians in every direction dare not look down on China, and that traitors and rebels dare not covet the imperial throne! Confucius: How magnificent! Shun and Yu possessed all under heaven, yet did not claim it for themselves! Li Bai: One man can hold the pass against ten thousand! "Energy levels sufficient. Activating livestream System." Muruman connected the two planes, letting Earth in the interstellar age see with its own eyes the treasures of Chinese civilization that were everywhere in museums, school textbooks, and people's daily lives. Like dazzling stars in the night, like brilliant detectives revealed after the dust was wiped away, they shone with unparalleled brilliance. One cultural symbol after another reappeared on Earth, unleashing powerful spiritual might to slay their enemies and defend their homeland, striking fear into all who came from afar! Recently, Chinese culture, having rediscovered its roots and soul, has become all the rage across the stars. The most advanced planets have been reproducing it everywhere with the latest technology. Graceful figures in flowing-sleeved dresses, hair bound in cloud-shaped buns, danced with books in hand, displaying a unique rhythm and beauty. Dozens of ancient instruments, unheard of until now, played together, bringing back the splendor of a court feast from a thousand years ago. One sage and renowned figure after another came back to life to personally recount the evolution of Chinese civilization. The Alliance's humans, now a subordinate species: !!! Earth is safe, and it's famous now too? An alternate universe, with a very liberal take on history. Theme: Civilization is the most fundamental, profound, and enduring force.
