The Fourth Ring Magic, Eye of Truth, was more powerful than Milton Cheney had imagined.
This magic is a superior version of the Spiritual Eye Magic, and is the first Fourth Ring Magic he mastered after becoming a Level 4 Wizard.
It not only possesses all the features of the previous Spiritual Eye Magic but is even more powerful.
It has even brought in a new function: marking.
Milton can monitor the condition of a person or object marked by the Eye of Truth at any time.
In other words, as long as Milton wants, he can keep an eye on someone without them knowing.
Of course, this has a distance limit. It is limited to the Wizard Realm.
In other words, if Milton leaves the Wizard Realm for another world, he naturally will no longer be able to see the person or object he marked with the Eye of Truth.
Even so, this is still quite exaggerated.
It is limited only to a single world.
