Light traveling from air to water: When light passes from air, a less dense medium, into the water, a more dense medium, its speed decreases, and it bends or refracts towards the normal line perpendicular to the water's surface. This change in the direction of light is responsible for making objects submerged in water appear displaced or distorted. That was interesting and all, but it wasn't time for Rain to think about that since numerous water spears emerged from the river and flew toward him.
"I should have known that those guys would be in a tribe like this as well," Rain thought.
Somehow, the water spears could move even faster than Rain, so charging ahead wasn't an option. Still, he instinctively knew the weakness of such fast attacks. Rain jumped to the side and spun in the air to avoid the projectiles, and they hit the ground while making it tremble.
