Under normal circumstances, the flying shuttle was isolated from the outside world and would not feel the environment of the outer universe.
The flying ship that Cui Heng had personally built naturally had such an effect.
The reason why they felt cold was not because of the physical chill, but because they naturally felt a chill when they looked at the Dark Sea Star at a close distance.
This meant that the cold aura enveloping the surface of Dark Sea Star was no longer just material cold.
It was also cold on a spiritual level.
If one did not have a strong enough soul and will, they would probably die directly because their soul would be frozen by this strange chill when they looked at Dark Sea Star at a close distance.
Perhaps this was one of the reasons why it was called Dark Sea Star.
