Today, I had a sudden inspiration and decided to experience a "deep-sea adventure" - not in the real ocean, but in the deep bathtub at home. When the bathtub is filled with warm water, the water surface ripples slightly, reflecting the ceiling light, as if it were a shrunk lake. I took a deep breath and slowly sank into the water, diving into that deep underwater world. At that moment, a wonderful sensory journey quietly began.
