บท 70: The Goddess of Luck really hadn't let him down this time?

Listening to Elena, it seems the Mysterious Mine is more valuable than imagined?

Mike feigned interest in the topic and asked, "What kind of ore is considered high-quality?"

"In the Tower of Truth tier assessment, ores graded B and above are considered high-quality."

Elena was very accommodating, answering each question carefully without discriminating against them for their lower talents. 

After all, the [DDF] combination on this Battle Vehicle had already become quite famous before even reaching the training summer camp. The trio had inadvertently become celebrities!

"Thank you, senior."

Mike suppressed the urge to ask more, storing this information in his mind to inquire later at Wolf's Den with Maxen Stoneheart. 

B-grade ores are considered high-quality. If Mike remembered correctly, the worst ores in his two Mysterious Mines were B-grade?!
