Entering the tomb

The others followed suit, and entered the ancient tomb as well.

Though this burial mound looked like a hill from the outside, the passageway inside was only wide enough for around five people to pass through at the same time. Its height was around three meters, with stairs that led all the way down.

This was clearly a hill-like burial mound, but why were the stairs going downwards?

Everyone did not know what the reason was. In any case, this staircase was designed just like this, and their only option was to just walk onwards.

It was very dark here, but it did not affect their visibility. As long as there weren't any unique Regulations in place, pure darkness had completely no effect on Celestial Kings.
