With the aid of "Light," Cohen's work sped up considerably. Not only did the speed of his digging double, but he also had a sense of direction underground.
This was a great help to his work, allowing him to avoid constantly recalibrating his position, and instead, he continuously dug a diagonal corridor thousands of kilometers long.
In theory, such unsupported holes are prone to collapse, but after all, this is a mythic world, and the site of the Mount of the Gods is extraordinary. So, as Cohen dug downward, he encountered no accidents along the way.
During the excavation, in order to obtain food, Cohen also hunted beasts multiple times. Gradually, he found that creatures like the giant beast he encountered before were not uncommon.
