Looking at the photo of Mo Niang risking her life to open a sealed door, Thomas became somewhat agitated.
He had seen the live broadcast where Lincoln nearly lost his life abroad!
Nevertheless, this was simply a case of worrying too much. He quickly realized: Mo Niang was a Mechanism Girl, although her intelligence was extremely high, and different from a regular person, she was essentially a product of the Mechanical Art.
She appeared almost human, but beneath her beautiful dress were sophisticated spherical joints, a typical feature of a Puppet.
Although she is more exquisite and beautiful than any Mechanoid, Clockwork People or Clockwork Monsters in Mechanism City, she is still a Puppet.
She doesn't need to breathe, so she won't suffocate, and she can withstand changes in air pressure better than humans. As long as she is not blown away into the endless space, she should be fine.
Moreover, Cloud Dream probably wouldn't be that heartless.
