Siheyuan: Trading Three Watches for Nuclear Weapons Technology

As soon as Lin Feng obtains the Transdimensional Trade System, he trades old artifacts for weapons far more advanced than their era and voluntarily tells the state everything.

A calligraphy-and-painting piece can be exchanged for a thousand tons of grain. An old-fashioned bicycle can get him a missile, while a few wristwatches are enough to obtain cutting-edge weapons and complete technical documentation.

When the navy lacks air defenses, he buys shoulder-fired anti-aircraft missiles.

When the fleet needs the ability to operate far out at sea, he sends destroyers, cruisers, and submarines to the docks.

Researchers are so excited by future technology that they stay up all night, while foreign fleets can only watch as a once-weak navy rapidly completes a generational upgrade.

Lin Feng rises from a junior procurement clerk at the Yanjing office to a senior naval official overseeing major classified projects.

Even the most unremarkable old item in his hands could become a national treasure capable of reshaping the world's military balance once it enters the trading space.
