Unlike rockets, the black Phoenix flying ship did not require a powerful thrust to overcome the effects of gravity. Hence, it maintained a very high elevation speed. Without realizing it, the black Phoenix flying ship had already risen to an altitude of about 400 kilometers above the ground.

At this height, the atmosphere was already very thin, close to the state of vacuum.

Moreover, everyone was already in a state of weightlessness.

For Xia ruofei and the others who were wearing the spacesuits, they felt more at ease in the zero - Gravity state. Although the cumbersome spacesuits still looked bloated, they seemed weightless.

Sound couldn't be transmitted in a vacuum.
