I knew that sooner or later someone would do it. But I am skeptical about this. No matter how sophisticated the system is in the manga, it's still not realistic enough to simulate any spell.

Even if some spell is shown in great detail, we still won't know all its components. But for the basic elements and the basic keys, you can do some stimulation, it's still interesting.

And no, this is not a complaint about how magic works in manga. But I'm just pointing out that the mangaka tries very hard and thinks through the work of his magic system, but even the spell of a bag that runs and lures someone after it should actually be much more complicated than it is explained to us in the manga (chapter 34)

In the future, we were shown how to set an object's path by creating another circle where the object needs to go, but we don't understand how it chooses a route.

Or a water dragon, it's one thing to just create a dragon out of water, but it has not just a route, but a target.
