On a rainy night, a meteorite crashed into the laboratory, and nine engineers, including people and equipment, penetrated into the Tang Dynasty.
No money, no status, no backing.
But He Ran didn't panic. He has metallurgical experts, mining experts, materials experts, mechanical experts - a whole national team.
Binary punches, telegraphs, electric lights, artillery... They started the industrial revolution in the Tang Dynasty from scratch.
The Minister of the Ministry of Finance was dumbfounded: "This account can be settled faster than an immortal!"
As the rebels approached the city, the improved Tang knives cut iron like mud, and the water-powered forging hammers worked day and night.
An Lushan gritted his teeth: "Who is that He Ran?"
Fifteen years later, He Ran saw his handwriting in a yellowed letter:
"I am you and you are me."
Nine people, no one can be missing.
