Mi An, a top modern security expert, accidentally traveled to a magical alien world, only to find that his best tactical layout was vulnerable to mages and knights.
He decisively abandoned the traditional combat route and integrated modern security concepts into the magic system: risk assessment, magic monitoring, contract countermeasures, special equipment research and development...
Starting from protecting a priceless dragon egg, his "Dark Blue Security" became famous in the outside world.
The royal nobles regarded him as a thorn in their side, and the underground forces wanted to get rid of him quickly. Even the gods began to pay attention to this existence that disrupted order.
When a divine war-level disaster strikes and all the major forces are helpless, Mi'an's company becomes the last line of defense.
"Everyone," he announced calmly while standing in front of the magic defense matrix, "please leave professional matters to professionals."
