By the way, the first stage is when the whole <> surveyed the ground from the sky, and the second stage is the scanning by > and >.
And now, the investigation begins with the method of sequential examination of shallow underground areas by <>100 units with >.
Here is how the old man would do it.
First, divide the northeastern part of Rasil into 100 square kilometer squares.
The area is about 500,000 square kilometers, which is 5,000 squares.
The total area is about 500,000 square kilometers, which is 5,000 squares.
If we assume that the time required to survey each square, including travel time, is one hour, it will take 50 hours = a little over two days to complete the survey.

If nothing is found, the searcher will go to a depth of 1,000 meters.
If something strange is found, the exploration will be more careful.
The concept of << strange part> is very vague, but in short, it is something like a trace of the construction of an underground city.
Partially collapsed bedrock, rocks that should not be in the formation, or strangely geometrical holes with circular or straight cross-sections, etc. are suspicious.
And if you have done a survey in the vicinity of the , you should be able to find traces of it much faster .......

It has been half a day since the RAND team and the ground searcher were deployed.
There are no reports yet, but we are getting a pretty good idea of what's going on underground on the <>.

The shallowest point is 200 meters deep, and the deepest is 500 meters deep.

Even though the bedrock of the Rasheel continent is rich in rare metals such as mithril and adamantite, it is difficult to mine at such depths.
<<>
It will take time because of the reflection and the obstruction of the transmission of the magic wave.
However, he thought that it would take only about 20% more time than planned and it would be finished within three days.

It is a sad guess, but at the same time it could be the order of the world.
There is nothing eternal in this world.
But <>.
he said.
The old man is examining the information that Rando's group is giving him and sorting it out.
And....
<> This is ......>>
The information from Land 567 had some interesting details.
There is a crushed stone belt at a depth of 645 meters.
Based on this information, the old man used a <>.
Using the telescope, he slowly and carefully examined the surroundings.
The rocky strip was almost vertical.
It had spaces like a < in some places, and then it shifted its axis a little and extended vertically upward again.

The design of the roof is such that rainwater does not directly enter the roof and does not fall down in a straight line to the bottom of the roof.
The fact that the hole, which is supposed to be a vent, is filled with crushed stone means that it has been disused for a long time.
Perhaps what lies beneath is not so much an underground city as an underground ruin.
