Above the Raging Sea, the Age of Steam

Also known as the single female protagonist of "My Battleship is Actually a Time Traveler", Gray fog always hangs above the sea level, and the salty sea breeze rolls up fine waves, lapping at the scattered landmass called "human fire". The world has long been reshaped by the sea water, and 99% of the old territory has sunk into the abyss. Only the peaks of a few mountain ranges are left above the sea, embedded in the boundless sea like broken teeth. People named these remaining footholds "Fengdao". Each peak island is a vertical city, with wooden and iron houses stacked up along the steep mountain walls, layer upon layer until the top of the mountain is shrouded in mist. The foot of the mountain was transformed into a crude dock, where rusty steamboats loaded and unloaded fresh water and dried fish - the most precious supplies today. In the vast sea between the islands, there are countless "floating cities" built with driftwood and air bags. They are like fragile eggshells, rising and falling slowly with the waves, maintaining contact with human society by relying on the ropes connecting Fengdao. Human civilization has long since retreated into the folds of the steam age. Gunpowder became a vague vocabulary in ancient books, and was replaced by steam-driven weapons: the "roaring cannon" mounted on the cliff of Fengdao required three strong men to turn the crank for ten minutes to build up enough pressure. When the cannonball flew out, it was enveloped in a white cloud of steam, but it often fell into the sea hundreds of meters away from the target; the "steam rifle" worn by the soldier's waist was more like a funny toy. Every time he shot, he had to pull the piston to recharge. The bullet range was less than fifty meters, and the hit rate was even worse than that of a thrown spear. Electricity is a scarcer thing than gold.
