Bringing Technology to Great Qin, I Turn the First Emperor Into a Wallfacer

In the year 4736 of the Chinese calendar, China is trapped under Western technological blockades and cultural infiltration, with its civilization on the brink of collapse.

The only chance to break the deadlock lies in the Qin Empire, two thousand years in the past!

Qin Yu is given seven days to prepare. He memorizes scientific texts and complete blueprints for steam engines and gunpowder weapons, packs high-yield crop seeds and remedies for wounds and poisons, then transmigrates back to the Qin dynasty on a one-way journey.

When he meets the First Emperor, he skips the theatrics and tells him everything. Spreading out a map of the future world, he describes the chaos of the Five Barbarians overrunning China and the century of humiliation in modern times.

Ying Zheng smashes the imperial desk in fury and vows to protect China for all eternity. He appoints Qin Yu as Imperial Preceptor and launches reforms across the empire: construction of the Lishan Mausoleum is halted, and a million convict laborers are put to work smelting steel and mining coal. The quest for immortality is abandoned in favor of forging firearms and building armored steam warships.

The butterfly effect of time and space sweeps into the present. While Western experts still boast of their technological monopoly, archaeologists unearth a Qin steam engine from the First Emperor's mausoleum. Overseas history books are rewritten, recording how a Qin army armed with firearms swept across Eurasia.

One man transmigrates to ancient times, and one emperor turns the course of a thousand years. Across two millennia, the First Emperor cuts a path to survival for China in the future.
