A pot of boiling water cannot boil away the suffering of the world; half an account book cannot account for the sufferings of the people in troubled times.
When the soul of a modern manager fell into the death row camp on the eve of Yashan, what Lin Zhao faced was not the passion of the iron horse, but the desperate situation of rampant plague and human life. There is no system, no golden fingers, he only has the logic and rationality of modern civilization - using boiling water to disinfect and control the plague, using double-entry accounting to tear apart the shady curtain of corruption, and using the principle of leverage to build survival fortifications.
From the accounting room of the death row camp despised by everyone, to the Yunzhou guard in charge, to the empire builder who rewrote history, he used technology as a spear and the system as a shield to forcibly carve out a bloody path for industrial civilization on the decaying feudal body.
This is a cruel collision between modern thinking and ancient feudalism. It is a dimensionality-reducing blow to the solidification of interests caused by technical barriers.
