"Lilith, you didn't use mana, did you?" he asked, his tone containing traces of exhaustion.
He had lost track of how many times he had been through this same scenario. The intruder came, Meph failed to stop him, and they repeated the cycle.
But his exhaustion continued accumulating, whereas the intruder's didn't seem to go down in the slightest. The boon of immortality, or some other technique—he did not know.
However, there were some changes during all of these scenarios. One was the fact that Lilith had now learned how to properly control mana. She had also grown a bit, looking like the average healthy teen.
Of course, the biggest change was, "Yup, I made a fountain this time!" Lilith exclaimed with a cheery laugh before running up to Meph and hugging him.
At some point, he stopped disallowing her to use mana; instead, he encouraged it. If she was going to use it anyway, why not learn how to do so faster?
