An airship that used to fly in the sky. But now, it can soar in the deep ocean as a sub. This is my first sub so it may have many problems and, U guys might not be satisfied with it, but these issues won't affect its operation. I'm trying to make it better. Originally, the airship's balloon was filled with air, so I thought putting other things in it isn't a good idea. I decided to freestyle it. If U do not like it, just delete them. If U found any issue of this sub, pls tell me, and I'll appreciate it. :)
