I Build a Fairy Boat on Endless Rainy Nights

Song Si traveled to another world, where it had been raining for three hundred years and it still never stopped. Heavy rains flooded the earth, bringing countless strange things. Human beings remained on the houseboats on the water and the only remaining highlands. Song Si's houseboat can swallow strange objects, build various strange components, and gradually evolve. When the world was completely engulfed by heavy rain, his ship slowly rose. "Welcome to my fairy boat."
