He has eleven points of mana.
His students have hundreds.
And somehow, the System just made him their professor.
Kaiven Rell barely survived his last Tutorial Floor. His mana channels are ruined, his regeneration is almost gone, and casting anything stronger than a minor spell could finish the job.
So naturally, his next assignment is Veyrhold Academy.
Role: Assistant Professor of Practical Mana Theory.
There is just one problem.
Veyrhold claims Kaiven has already worked there.
The Academy has his records. His handwriting. His research. Even a syllabus he supposedly wrote months before arriving.
Kaiven remembers none of it.
Teaching should be impossible with almost no mana, but Kaiven soon discovers something his far stronger students have missed.
Power is not everything.
If you understand exactly how a spell works, sometimes one drop of mana is enough to bring the whole thing crashing down.
As Kaiven teaches his class to break magic apart instead of simply throwing more power at it, strange things begin happening across the Academy.
Classrooms appear where walls should be.
Students vanish from the records.
Professors know things they should not know.
And one missing student is erased so completely that Kaiven becomes the only person who remembers she ever existed.
Then there is the Interstice.
A massive gathering place connecting Tutorial worlds, ancient civilizations, deadly quests, powerful guilds, demons who should never be trusted with contracts, and attendees so strong that Earth's greatest fighters barely register beside them.
Somewhere among them is Saeryn Thale, the most powerful active Tutorial attendee anyone knows.
And she recognizes Veyrhold.
She has been searching for it for years.
Because people have entered the Academy before.
Not all of them came back.
Now Kaiven must uncover what Veyrhold really is before his students become part of its next lesson.
Fortunately, when you only have eleven mana, you learn to make every point count.
A dungeon-academy Progression LitRPG packed with tactical magic, dangerous quests, System mysteries, strange classes, powerful guilds, an extremely questionable demon, skill evolution, underdog progression, and a protagonist who would rather understand the rules than obey them.
