Roland's floating city stayed where it was for about half an hour, before it gradually rose back into the clouds.
Feelings were always subjective.
For example, the World Tree thought that she had a 60% chance to beat Roland even though he had a floating city.
Roland, on the other hand, thought that he could 100% kill the World Tree with one tritium bomb.
Andonara, evil gods, the Demon Gods, and other experts could quickly escape from the dreadful heat and radiations from the center of the explosion by moving fast.
When in a perfect environment, a nuclear explosion couldn't kill them.
However, it wasn't the case for the World Tree.
The World Tree was too big!
She was essentially an inferior version of a floating city.
She was also a source of enormous magic power. She was even alive.
However, her greatest shortcoming was her immobility.
The floating city was much more awesome in comparison.
