Splash, splash.
The sound of the water grew more and more intense, from the initial flow turning into a torrent, crazily pouring into the room.
Within a mere ten minutes, the water had already risen above William Cole's knees.
William Cole's expression darkened slightly as he made a preliminary estimate. Considering the speed of the incoming water, the room was about four meters high.
His knees were approximately fifty centimeters from the ground. In at most eighty-plus minutes, roughly an hour and a half, this room would be filled with water.
By then, if the water couldn't flow out, William Cole would be suffocated alive.
As time grew increasingly pressing, William Cole couldn't afford to think further. He frantically searched for a mechanism or exit around the room.
Even when he utilized his X-ray eyes, he found no mechanisms on the walls surrounding him.
