As the "Deep Sea Explorer" delved deeper into the exploration, the atmosphere inside and outside the submarine became increasingly tense and mysterious.
The submarine slowly descended into the Baling Pond Strait, and the noise from the surface was gradually replaced by the tranquility of the deep sea.
As the numbers on the depth meter climbed, the interior lights of the craft intertwined with the blue glow of the control panels, becoming the sole source of light.
Despite the faint light from the outside world, the submarine's observation window, aided by advanced night vision technology, made everything clearly visible.
The water exhibited a profound azure color, with occasional faint bioluminescent glimmers from living creatures, like the most distant stars in the night sky.
