Need to Know: A Military Isekai LitRPG Adventure

By Nâdiya

In a world ruled by magic and prophecy, the most dangerous weapon is information.
Military intelligence officer Elias Thorne wakes on the cold floor of a Valerian dungeon with no army, no authority, and no explanation for how he arrived.

Then the System activates.
Instead of granting him legendary strength or destructive magic, it assigns him the Insight class-a progression path built around observation, interrogation, deception detection, and tactical analysis.

His first test is a battered enemy prisoner carrying information that could save an entire army. The Valerian commanders trust their Oracles. Their Chosen Champion trusts an ancient prophecy. Elias trusts the details everyone else has ignored.
When the enemy begins moving beyond the reach of prophecy, Elias must build an intelligence network from prisoners, discarded operatives, political outcasts, and people no commander considers valuable. Every secret he uncovers earns progression. Every successful operation unlocks stronger abilities.

But the System is not a mind reader.

Skilled enemies can resist it. Spies can manipulate it. Prophecies can conceal as much as they reveal. To survive, Elias must combine his new abilities with the human tradecraft he possessed before entering this world.
Because the enemy has its own Spymaster.And she already knows someone is watching.

Is the story heavily focused on statistics?
The book contains meaningful progression and System panels, but the statistics support the narrative. Readers can follow the story without studying every number.

Yes. Book One completes its central military campaign and character arc while leaving room for Elias's intelligence network and larger conflicts to continue.If you enjoy intelligent protagonists, military progression fantasy, political conspiracies, tactical warfare, and victories earned through strategy, enter the world of Need to Know.
