The moment Vishnu saw the Spaceship his heart was filled with awe at such a massive size. He didn't know what it was but he has the ultimate guidebook in the shape of an old man in his ring. Arthur explained to Vishnu what a Spaceship is. Until now Vishnu thought that Star force realm cultivators use their bodies to travel through space while it is true that after reaching a certain realm one could do that early stages of Star force realm cultivators couldn't do that. Even then they'd be much slower than an advanced Spaceship.
Jiaxin and Lily also became stunned seeing such a massive thing that covers a whole city. Fenrir was in hibernation otherwise it'd also probably give the same reaction as them.
