The Hydra's answer stunned everyone. They didn't expect the Hydra to not know about it after he built such suspense about the whole thing.
They realized that the nine-headed Hydra was being sarcastic! "The Light Princess is in the underground ruins. She is fighting the ancient dead souls now."
The Lords didn't understand what the nine-headed snake meant. But their heroes understood.
"It looks like she is in trouble," said the Fallen Angel in a serious tone of voice.
As the former deputy to the King of Heaven, he had more understanding of the ancient empire than the others.
That ancient empire had been destroyed precisely because it threatened the King of Heaven!
While the Fallen Angel and the others were dealing with the Light-Types, Su Wan took another path down to the underground ruins with Xu Yuan.
