Lin Yuan, a man from science and engineering, traveled across the Tang Dynasty and became a poor boy from a poor family.
No system? It's enough to have a brain - coke to make steel, gunpowder to defend the city, and steam engines to change lives. I used modern technology to turn the Tang Dynasty over from its roots.
But technology is not the most difficult thing to crush, the most difficult thing is——
The prince is going to be deposed, the king of Wei is going to rebel, and the princess's brothers are all on the road to death.
And the girl named Princess Changle was standing on the tower playing drums for him:
"Lin Yuan—you have to come back alive—"
He looked up at her, and then at the Tang Dynasty at his feet——
Okay, now that I'm here, I'll change this destiny.
By the way: Why do the sisters of this princess call me brother-in-law?
