Diana managed to get back to the continent where the elves were located in just a matter of a day. That was simply because of the speed that she possessed, and the only reason why she had been so slow was because she was carrying Amon along.
If she had been alone, she would have definitely been able to arrive there in just a matter of a few hours. But since she had to make sure that Amon did not die, she had to reduce the speed at which she was moving at.
Amon was completely surprised by the speed that Diana was moving at. After an entire day, he finally realized that it was not that Diana was actually using an item in order to be able to move at such an incredible speed, but instead, it was simply due to the ability that she possessed.
At that moment, he could not help but be completely horrified about that fact. If it was true that Diana was already this strong, what would happen if she really wanted to kill him?
