Rival

The two guide demons really were leading the way sincerely.

They were humble along the path; it would have been perfect if they were carrying the lizard.

After diving down a hundred meters, the real tunnel appeared.

On Mars, there was water in certain locations, but there was not much, as rain was not present there.

Due to this, it was easier to dig a tunnel, they need not be worried about rain falling and destroying it. The tunnel was wide, and the major and minor roads were easily distinguishable.

The major road was more than ten meters tall and ten meters wide, while the minor road was only two to three meters tall and about seven to eight meters wide.

Regardless of the type of road, they all had clean surfaces and both sides of the walls were stable as well. There was no need to be worried about structures collapsing.
