— Show me the palm of your hand. — She did; I took it and placed it on the pyramid—. Activate your diving mask. — Already both protected—. Mr. Kim, we will start and get as far away as possible if there is poison.

— Okay.

I breathed, and without thinking, I cut her hand; she shrieked and let the blood run over the artifact. Then I placed it in the hole and turned it to the left as indicated. At first, there was a high-pitched screeching sound, and I looked out of the corner of my eye at Anjil, somewhat startled. Then the wall began to move, and as it opened, a fine powder was ejected around us.

— What is that?

— These ancestors were picky; if someone undeserving was next to you, they would surely die from this poison.
