Feng Jun directly teleported to the sea near Hawaii and happened to arrive underwater during the daytime.
So he had to forcibly wait until nightfall before surfacing and releasing the Warship Combined Body from the Spirit Beast Bag.
When Feng Jun agreed to escort these people back to Earth, he clearly stated that during the operation, the warship must enter a dormant state, and everyone must enter the warship's life-support pods, otherwise he would not go to Mars.
This life-support equipment is standard for warships, not only to deal with potential warship damage but also because when the warship transitions, fleet members must be inside this equipment.
Otherwise, the spatial distortion from the transition, while having little impact on the warship, can be deadly to organic life.
