What is the direction of this suction?
As Fang Huai tried to discern it, his sense of direction faded away again.
He checked his air pressure gauge, which read less than 6 megapascals—almost at the warning level.
It was time to ascend.
He wasn't particularly worried, but he was concerned the people onshore might be getting anxious. In the span of a few minutes, they had sent him several feedback signals through the safety rope.
His breathing rate was much lower than that of an average person. Now that his air supply was down to 6 megapascals, he figured He Zhijun and Lian Xu had probably surfaced a while ago.
With no clear sense of depth or direction, Fang Huai could only attempt to ascend slowly and as vertically as possible.
The ascent took a long time.
Nearly six minutes to reach the surface.
