"It seems that Dimitri has done a good job." Noel smiled. 

Noel and Anna had returned to the previous ruin, finding a pile of demon crystals. Each of them was at least Advanced Level and there were three Superior Demons Crystals.

"Indeed. Your plan?" Anna asked. 

"Yes." Noel nodded, recalling the discussion between him and Dimitri.

"So whenever I encounter the ancient ruin, I will be cleaning it from all demons. Once we're done, we'll go to the surrounding area, killing as many demons as possible. After that, we'll go to another ancient ruin and return several days later."

Dimitri crossed his arms. "But if that's the case, are you planning to absorb the demon crystals on the spot?"
