When I opened my eyes, I actually traveled to the most precarious moment in the Southern Song Dynasty - in the third year of Jianyan, Zhao Gouzheng was forced to flee south by boat by the Jin soldiers, and half of the country was about to overturn! There is no system, no superpowers, only modern knowledge and a hiking bag stuffed with "black technology" (75% alcohol, water purification tablets, "The Barefoot Doctor's Manual"... And the Portland cement formula stored in the mobile phone!).
Goal: Help the coward Zhao Gou rebuild a different Southern Song Dynasty on the ruins that is capable of fighting and resisting!
My strategy: don't engage in metaphysics, only engage in hard-core infrastructure!
"Prophecy" saves lives + "magic medicine" establishes power: Relying on historical knowledge to escape the pursuit of the golden soldiers, using modern medical knowledge to stop plagues in the army, and transforming from a "monster" into a close minister of the emperor "waiting for an edict".
Lin'an was transformed into a "super construction site": "Song Dynasty cement" was burned to build fortress walls and the Qiantang seawall was built; "public health orders" were implemented to build toilets and isolate people to fight invisible killers; agricultural techniques were improved to increase food production and stabilize the foundation of people's hearts.
The military industry has undergone explosive changes, and famous armed generals have: assembly line manufacturing of armored crossbows, granular black powder upgrade "fierce oil tank", standardized parts for quick battlefield repair! Send Yue Fei and Han Shizhong "Tiantu" enemy information, and change water transportation to ensure logistics, just to create an iron army that can fight against the enemy!
Playing with finance and information warfare: "Salt Yin Futures" engages in financial reconstruction, movable type printing engages in psychological warfare, and the Imperial City Secretariat uses "codes" to build an intelligence network!
The Southern Song Dynasty, which has been transformed by my "hard core", has a stronger foundation and more powerful minions. Although the stubborn feudal disease cannot be cured, when the Mongolian iron hoof goes south in the future, they will definitely run into something that far exceeds history - the Iron and Steel Southern Song Dynasty!
