On the first day after traveling through time and becoming an ordinary student at Super Theological Seminary, the protagonist discovers that the physical training here may really kill people. The alien civilization casually mentioned in class may be peeking at the earth, and the door that should not appear in the training ground does not lead to the simulation program.
There is no divine body, no king's blood, and no plug-in to sweep the universe with one click. Facing super soldiers, alien fleets, and seemingly inviolable dungeon rules, he can only rely on his incomplete original memory, common sense, observation, and a mouth that refuses to shut up to fight for a way out for himself and his teammates.
When a training accident turns into a high-risk scene, when the choices in the dungeon begin to change reality, the familiar heroes and disasters gradually deviate from the track in memory. The protagonist must make a bet between "knowing a little bit about the future" and "actually nothing is certain": saving a person may trigger a war in advance; following a rule may just fall into the trap designed by it.
