Refining Black Oblivion Thunder

"What exactly are the sub-dragons?" asked Holy Infant after some thought.

Arctic Wizard replied, "It should be the Earthquake Dragon. Perhaps it's a descendant of the adult sub-dragons from ten thousand years ago."

Holy Infant asked, "There aren't any adult sub-dragons in that place, right? They're level 6 beings. They're extremely dangerous."

"Definitely not," said the Arctic Wizard. "A level 6 sub-dragon is extremely powerful. If there was, I would definitely be able to sense it!"

After considering for a moment, Holy Infant said, "I want to make a copy of the Spirit Concentration Technique and the Crystal Fragment Technique. I also want a copy of the experiment log. I only need a quarter of the other treasures and resources in the relic. You and the other person can discuss the remaining three-quarters. How about that?"

Actually, what Levi needed the most was not these techniques.

Instead, it was the three-headed Earth-type sub-dragon!
