Under the Vermilion Stele

After the global tech lockdown caused by the 'Vermilion Meteor' incident, technician Shen Ke finds hope in a lost ancient manuscript of the 'Wooden Ox and Flowing Horse'. Joining iron-drawing master Ye Zhiqiu, he reconstructs a water-powered hammer based on gravitational potential energy, verifying a precision manufacturing path independent of electricity. Facing acquisition and blockade by capital groups, Shen Ke gathers the ancient wisdom of craftsmen across the country. He eventually opens the technology to the public, successfully builds a pure mechanical precision machine tool, and launches the 'Civilization Reserve Route' plan, carving out an ancient yet new path for the survival of human civilization.
