The audience might be watching a ten-minute short show, but the script implemented on the stage can reach thousands of years!
This is the horror of a puppet master's domain, especially someone as powerful and 'creative' as Wilhelm.
In just a few seconds, countless celestials aged and died on the stage while others broke their wings, completely unable to fly without the threads that manipulated them.
This speed of killing thousands of people in a few seconds is too scary!
Even if the celestials who chose to act on the stage died or broke their wings, Wilhelm still used them as puppets, but he would also replace a large batch of celestials on the stage with those still intact.
These people couldn't resist the rules inside the domain at all, and those who could create domains weren't placed on the stage or backstage at all.
