Although there was still no ironclad evidence proving that the "Reincarnation Box" refined by Ivo and the "Casket of the Undead's Reincarnation" mentioned by Frost were the same mysterious object, there were indeed some similarities between them.
The most obvious was their names. Both were mysterious objects, yet they bore similar names. That should have been quite rare.
Of course, similar names could very well have been a coincidence. After all, Ivo's "Reincarnation Box" had been marked as a provisional name.
Beyond the name, there was a second similarity. Mysterious objects might not have been uncommon, but mysterious objects with similar names that had both gone out of control were exceedingly rare.
Frost had mentioned the "Casket of the Undead's Reincarnation" in the first place because he had used that mysterious object to explain what "out of control" meant to Angel. And the signs of collapsing rules when the Reincarnation Box mentioned by Fingernail Granny had manifested in the world essentially confirmed that it, too, had been out of control.
Going out of control was extremely rare among mysterious objects. Moreover, according to Fingernail Granny, the Reincarnation Box had been refined in a small world near the Southern Region; Frost had also said that the Casket of the Undead's Reincarnation had been discovered in a world near the Southern Region. The fact that both had been near the Southern Region pointed to something.
Perhaps this evidence could still have been a coincidence. But if he worked backward from the conclusion, things became interesting, because even more similarities would emerge.
Suppose the two had always been the same mysterious object, and Alex and Ivo were indeed connected—perhaps they were even the same person.
Then many things could be explained.
For instance, Frost had once said that the Reincarnation Box was actually
