Chapter 839: The Fourth Trial 12

Everyone took several steps back in order to get a clearer and more direct view of the content above.

The first drawing depicted an irregular rectangle enclosing an arched semicircle.

After studying it for a while, Su Tang finally guessed that what was depicted was This Cave that they were seeing now.

The second painting was also very simple, featuring two rectangular frames one above the other, each containing an irregular curve with multiple small dots at both ends.
