Dungeon: I Can Fix the Entries of Anything

Dragons roared, and thick fog spread as Duncan transmigrated to a supernatural world resembling the Middle Ages.

When he awoke, he found himself a Corpse Collector in a dungeon, buried under a mountain of debt.

Duncan thought he would spend the rest of his life struggling to survive in this supernatural world, until he discovered that he had awakened the "Manual of Myriad Things."

By carrying items, this manual could grant him all kinds of traits.

Once an item was recorded on one of its pages, its trait became permanently fixed. He no longer had to carry the item to benefit from its special [Trait] bonuses.

Record [Damp Firewood]: Gain the trait [Unquenchable Blaze], learn Fireball, triple the rate at which you master flame magic, and gain health regeneration.

Record [Expired Bread]: Gain the trait [Breeding Ground of Disease], lose less health when bleeding from injuries, greatly increase poison resistance, and regenerate severed limbs.

Record [Tyrant's Contract]: Gain the trait [Disorderly Sovereign], counter rule-based abilities, and become immune to all physical attacks.

Even more absurdly, as long as certain conditions were met, an item's trait could be [Permanently Fixed], freeing up its page so the manual could record even more items!

While other supernatural practitioners worked themselves to the bone training, Duncan could grow stronger just by scavenging wherever he went!

The dungeon: iron and blood, mystery and the unknown.

This was an age where reason and madness coexisted, with schemes by the Church, fallen witches, and the corruption of Outer Gods.

But with Duncan around, it would never become the worst of times.

Because his manual was filled with [Eternal in a Single Thought], [Immortal and Undying], [Usurpation of Fate], and [Overlooking from Higher Dimensions].

I've read the premium-hit works Lord of the Mysteries, Cell Prison, and No. 13 on Mingke Street.
