Reviewing Dragon Nation's Technology, I Burned Out Our Ancestors' CPUs

[Protagonist as a tool + modern technology on the sky screen + no modern history]

The eternal sky screen suddenly stretched across all the worlds.

It illuminated the Qin, Han, Tang, Ming, and countless other ancient dynasties.

Emperors of every era and their entire courts watched together as the true technological prowess of the future Dragon Nation was revealed.

Hybrid rice brought a thousand years of famine to an end. Vaccines and medical care drove away devastating plagues, breaking the fate of the ancients, for whom even minor illnesses could be fatal.

High-speed trains raced across the land, while megaprojects transformed nature and reshaped the vast territory.

Aircraft carriers and fighter jets stood guard over the coast, while the nation's mighty weapons protected the peace of countless homes.

One scene after another, each beyond the understanding of its time, played across the screen. The worldviews of emperors throughout history crumbled one after another, while the minds of their ancestors practically overheated from the shock!
