What Wrath said made Kelvin remember what Aganju had said about enslaving entities like Wrath, but he didn't dwell on that topic.
Instead, he asked about the matter that concerned him the most, "Can we find the entrance to the core of the world with how large Lignum is? How long does it normally take for the entrance to be found?"
Wrath shrugged and said, "It can take a year or ten years. I can't really guess when it will happen. But I can say with certainty that it will happen because the Yggdrasil civilization has honed their methods into a craft."
"The tool they use for searching for the entrance to the core of the world is the mark that every soldier carries. This mark turns every soldier into an expert scout. As long as a soldier passes by an entrance, we will find it."
"It is just that we might need to inspect every inch of the whole world, including underground structures. Even the ocean floor has to be scanned. That takes time."
