In 2025, construction engineer Tang Xiaojian died suddenly at the nuclear power plant construction site.
When he woke up, he was already on the deck of an ocean liner sailing to his motherland in the Pacific Ocean in 1977. He passed through his soul and became a "Harvard graduate student", replacing the young scholar who died in an accident.
What's even more bizarre is the barrage.
Trillions of netizens are "watching" his live broadcast, which is from 2025. He understands architecture, machinery, aerospace, and chips. The knowledge of the future traveled upstream along the barrage and poured into the land of China in 1977.
Tang Xiaojian started in infrastructure construction, building launch sites, wind tunnels, and factories, step by step from a "house builder" to a "country builder." He relies on netizens to guide him and discovers future talents who have yet to make a fortune - a substitute teacher in a mountain village will become a master in materials science in the future, and a factory apprentice will design a domestically produced large aircraft engine...
Someone is blocking it. The profit-seeking academic circles cannot bear to see China's rise as an overseas power. But Tang Xiaojian was not afraid.
From nuclear power plants to the stars and the sea, from infrastructure teams to the world's largest industrial country - this is his story, and it is also the story of trillions of netizens fighting side by side across time and space.
