While waiting for the centaurs to come back, I called Albert about what's happening here.
"They have the ability to detect lies? I guess centaur is the creature that my ancestor killed then. And you want me to come there with you so I can tell if they are lying or not when they promised that they won't tell other people, right?" Albert asked.
"Yes. They are quite smart. Also, they used to have the ability to see the future as well. At least very few among their kind. But today, there are no more centaurs with the ability to see the future anymore," I said.
"So it's not just my ancestor. Fabio's ancestor also killed a certain type of centaur to get the ability to see the future. Do you want to get Fabio as well?" Albert asked.
