On the night of the fall of the Yi Kingdom, Liu Xuan, a doctor of materials science, transformed into Dai Lu, the princess of the Yi Kingdom who was poisoned by a strange poison and was at the scene of a bloody massacre.
Facing the barbaric wilderness, powerful enemies, and the deadly poison in his body, Liu Xuan used his brain in science and engineering, and in a complex situation where the Three Kingdoms were at odds and surrounded by powerful internal and external enemies, and with modern materials and engineering knowledge, he worked hand in hand with He Lianzhuo, the "lone wolf guard" of the Yi Kingdom, to lead the Yi Kingdom to survive and grow step by step from the desperate situation.
From guarding Gushan to Ying Yang's defeat of the Qi army, from outsmarting the royal court to disturbing the imperial power of the Yue Kingdom, the princess with a doctorate in materials science used her unique skills as her blade and the world as her chess; the general at the end of the road used loyalty as her armor and mountains and rivers as her retainer. When the great cause of restoring the country is intertwined with the hope of detoxification, when the marriage letter of the new emperor of Yue and Helianzhuo's silent protection are at the same time...
This is an infrastructure legend about a hard-core technological princess who leads the remnants of her army to "rejuvenate the country through science and technology" amidst the sea of blood and corpses in the northern border. It is also a story of how two souls who redeemed each other in a desperate situation used their wisdom and flesh and blood to ignite a lamp of civilization that will never go out in the long night, and finally illuminate the entire era.
Purpose: When surrounded by big powers and powerful enemies, can your country and nation find a way out with your unique skills?
