Su Yan opens his eyes and finds himself on the island of Kalimantan.
No System, no supernatural powers, only knowledge a century ahead of its time in his head, and tens of thousands of fellow countrymen crushed beneath the feet of colonizers.
In three months, the red flag sweeps across the entire island.
When the colonizers of the old world scoff that this is a “rebellion doomed to fail,” they never imagine that...
A torrent of steel is surging out of the island's factories: production lines for independently developed rifles run day and night, refitted submarines quietly tear apart the hegemony of the high seas, and armored trains race across frozen soil and open plains, rewriting the rules of war with overwhelming force.
From the jungles of the South Seas to the northern snows, from the hidden currents of Tokyo Bay to the ruins of Berlin, he directs a global transformation forged from knowledge and industry.
Mockery gradually turns to fear, and blockades become retreats.
As the flags of the old empires fall one by one, the world finally hears, over the airwaves of a radio, the calm voice that changes the course of history:
“I am Su Yan.”
“The history of war in human civilization ends today.”
[Alternate history + high-stakes historical power struggle + no System + knowledge dominance + nation-building through infrastructure + global conquest]
Wouldn't your personal strength be strengthened? Otherwise, it would be too insecure. It wouldn't be too much for the time traveler to strengthen his physical and neurological reactions. At least he wouldn't be shot. This score is just right, 7 points
It looks better, keep working hard to update. Mainly because the subject matter is interesting enough.
