Core themes of the book:
When the wheel of history is rewritten by an ordinary young man, when the era of empires is overturned by the rules of the game, we see not only the rise and fall of a dynasty, but also the nirvana and rebirth of a civilization.
Final lines (Lin Hai stood on the armored ship, looking at the Pacific Ocean):
"Back when Zheng He made seven voyages to the West, he brought silk and porcelain. Today, what we bring are factories and railways. Times have changed, but one thing has not changed - the civilization on this land has always been worthy of being at the top of the world."
