During the Kangxi era, the Qing court maintained its rule through feudal autocracy, boasting of a golden age while keeping the country closed and the people's minds shackled. Meanwhile, the West had entered the tide of modernization: Britain enacted the Bill of Rights, establishing a constitutional monarchy; Prussia rose to power; and Peter the Great of Russia introduced reforms. The Royal Society of London and the French Academy of Sciences were founded in succession. Newton established the framework of classical mechanics, Leeuwenhoek opened up the microscopic world, Locke proposed the ideas of natural rights and the social contract, and the practical steam engine was invented. The gap between East and West widened rapidly.
Zhu Rui, an elite diver at a modern research institute, unexpectedly travels back in time to the Qing-Russian battlefield at Yaksa in the twenty-fourth year of the Kangxi era, taking over the body of a young Qing military officer. Armed with knowledge and vision far beyond his time, he plots and maneuvers amid the chaos, builds up the army, develops industry, and advances institutional reform, contending with the Qing court, Tsarist Russia, and the Western powers. Driven by a resolve to cast off the old and usher in the new, Zhu Rui breaks through the shackles of feudalism. After enduring political intrigue and bloody campaigns, he ultimately overthrows the Qing dynasty, shatters the old autocratic order, and establishes a new Huaxia founded on democracy and freedom. He leads his people in catching up with the tide of the world, forging a golden age of global supremacy.
