The most it could do was to increase Milton Cheney's understanding of this world.
However, Milton felt that his current understanding was entirely sufficient as he didn't plan to live in this world in the future.
Therefore, he didn't feel the need to understand everything about this world.
After all, in the history of this world, the Wizard Realm wasn't destroyed by the True Spirit Realm.
Perhaps, the destruction of the Wizard Realm had a lot to do with the True Spirit Realm, but ultimately, the True Spirit Realm wasn't the one who struck the final blow against the Wizard Realm.
Nevertheless, Milton had a premonition that he would inevitably be entwined with this world in the future.
Milton Cheney had great confidence in his intuitions, as they scarcely proved to be wrong.
Since he couldn't change the changes in the spiritual body consciousness, then it is best to just let it be.
