Belated Judgment

The protagonist died in battle and became a soul, but found that he could escape reincarnation and exist in the world as a soul for violating the laws of high-dimensional space. After making the second male assistant stronger, he enhanced his own abilities by cannibalizing his soul, used dimensionality reduction to combat crimes that leave no evidence in the world, and evaded the legal sanctions of high-dimensional space.
