Late Ming: The Furnace Fire Never Dies

Tragic Situation/Dilemma: In the winter of the second year of Chongzhen, Shen Li opened his eyes and became a small flag under the wall of Ji Town who had no enough to eat. The superiors have been owed wages for three years, their swords are curled and their armor is rotten; outside the wall, Hou Jin's army of one hundred thousand has broken through the barrier, and the cavalry will reach Zunhua in three days. The comrade said: Run, the Ming army is already in ruins. Cheap Finger/Reversal: Run? An [Industrial Map] lit up in his mind—given raw materials, given goals, and the process chain was deduced one by one. Others rely on blood to rebel, while others rely on an assembly line to rebel.

High-energy prediction + retention hook: In three months, the defeated army will become a new army, and the fortress will become an arsenal. When the Houjin Iron Cavalry finally hit the low earth wall, they were greeted by three volleys of fire. Huang Taiji thought he had captured a dilapidated fort until he saw rows of black muzzles on the fort wall - and behind the fort, there was a blast furnace that was smoking day and night. "I will set the rules for all firearms in this world from now on."
