Lancet Ruin

"A weeks ago, we have sensed some the activity of Grimm Monsters and sent a Master to investigate, and within a day we have lost contact with him, after that, we have sent a team of four, with them too we have lost the contact," 

"Three days ago, we sent the last two, they both had very good surviving skills, but twelve minutes ago, we lost contact with them too, with this as their last message," He said, hearing that my expressions couldn't help but become serious.

"Did anyone of them were able to find out what the Grimm Monsters are doing in the Lancet Ruin?" I asked, to which he shook his head.

"No, our assessment is the same; it is Master limit ruin which had been already harvested completely before it had reached our world," He answered.
