Leveling

Sadanari Utsugi was once nothing more than an E-rank provisional hunter, a forgotten boy sent into the deadly Mujin Depth with a party that never should have survived. When the dungeon collapsed, the world was told he panicked, abandoned his team, and died like a coward. That was the official record. Twenty years later, a dead gate opens beneath T okyo , and Sadanari walks out alive. The Hunter Association cannot rank him. The public system fails to measure him. The fake S-rank hero who built his fame on Sadanari’s stolen record begins to panic. And Miharu Shizume, the only woman who spent two decades fighting to prove his innocence, finally sees the dead man return. But Sadanari did not only survive the dungeon. He came back carrying the Abyssal Record System, a power tied to the oldest gates, erased witnesses, stolen hunter records, and a secret hidden beyond the First Gate. As every false record begins to collapse, Sadanari discovers that his betrayal was only the surface. Beneath the Hunter Association, beneath the global gate system, and beyond the Unreturned Archive lies a greater enemy that even the Archive itself fears. Now the dead E-rank must break every record, expose every stolen name, rescue the mother who hid him from the world, and face the truth behind what the Archive calls him: The door.

After dying in the most humiliating way possible over a restaurant bill, a normal man wakes up in another world as a tiny black snake with no arms, no legs, and no chance of surviving anything bigger than an insect. But before panic can fully destroy him, a cold system awakens inside his mind and reveals his unique ability: Fear Assimilation. He does not grow stronger by eating. He grows stronger when other living beings fear him. At first, he farms tiny amounts of fear from ants, beetles, mice, and small prey. Then he learns the real rule of this world: killing too quickly is wasteful, but controlling fear can turn even the weakest creature into a source of power. With every terrified heartbeat, he gains Evolution Points, sharpens his instincts, upgrades his body, and evolves from a helpless Common Snake into a dangerous Shadow Venom Serpent. As his abilities grow, he unlocks Fear Aura, Presence Suppression, Aura Concentration, venom upgrades, and the power to pressure intelligent beings without even revealing himself. His path changes when he saves a wounded white snake named Luna and chooses a new name for himself: Noctra. But animals are only the beginning. When humans see him and survive, their fear does not fade. It spreads through memory, rumors, and imagination. Noctra realizes that human fear is richer than instinct because people can fear what they do not understand. A monster seen once in the dark can become a story. A story can become a warning. And a warning can become a legend. Now Noctra is no longer just trying to survive. He is learning how to become the thing the entire world whispers about when the forest goes silent.

Emric Quist is transported to a medieval fantasy world inside a body too badly damaged to fight on its own. Instead of receiving a legendary sword or an overpowered magic class, he awakens an AI Drone System connected to an abandoned mechanical foundry. His first unit is Command One, a black quadrupedal drone with a cracked blue lens. It can hunt monsters, recover cores, defend roads, patrol dangerous territory, and help manufacture more machines. Starting with one drone and a medical bed, Emric gradually builds a network of anchors, public workshops, protected settlements, and autonomous units that keep fighting even when he cannot stand. But the Drone System is only one part of a much older network. More than three centuries ago, powerful mobile foundries were created to build roads, fortifications, transport systems, and public infrastructure across several kingdoms. Their bonded master died before ordering them to stop. Over time, their commands twisted. Settlements that refused their roads became unfinished construction, evacuating civilians became proof that more roads were required, and compatible bonded users became targets for forced control. When Vault Three rises beneath the marsh, Emric faces a 438-meter walking foundry carrying more than one thousand hostile machines. It begins turning bridges, treaty seals, borders, and entire settlements into its next expansion route. To stop it, Emric must work with Ysabet, the healer keeping his damaged body alive; Catrin, the strategist protecting his growing network through law and evidence; Cerys Dolven, Greyfen’s uncompromising civil leader; Marsh Prefect Maelin Rusk; and Orren Talvek, another bonded user whose eleven years of hidden decisions may have saved thousands while forcing others to pay the cost. Emric’s rise from one AI drone to a 120-machine network, the war against the Wayfarer Foundry, the creation of a publicly controlled Secondary Foundry, and the signing of the First Foundry Accord. Vault Three has stopped walking. Four more ancient foundries are beginning to wake.
