There were originally two shoes, but one of them was obliterated during the collision between the black hole, the Divine Suppression White Sun, and the Pay-To-Win Strike. As such, only one was left now.
Both the Divine Suppression White Sun and the Pay-To-Win Strike had complex origins, so the corpse of Wielder of the Will Fat Ball could not deduce any useful information from the two attacks.
On the other hand, a lot of things could be deduced from this seemingly ordinary shoe.
The corpse of Wielder of the Will Fat Ball grabbed the shoe and began to act instinctively—the corpse did not have the ability to think, so it acted according to predetermined patterns.
With this shoe, it could perform a series of operations such as aura detection, information tracking, and remote targeting to lock onto the owner of the shoe.
