Citadel for All: The Only Unit Angel at the Start of the Game - Chapter 494

Kael was a “rat”—a lowly stable boy in a frozen, brutal medieval world where Knights ruled with iron and Barbarians crushed skulls with bone clubs. His life was worth less than the manure he shoveled. That changed the night he butchered a Knight with a rusty dagger to pay a debt of blood.Chosen by the God of Slaughter, Kael awakens the Aether System. His cheat? The ability to project his soul into other worlds, live countless lives, and bring their powers back to reality—if he survives.But power is not free. It is bought with pain, time, and sanity.World 1: The Wild West. He spends a lifetime as “El Lobo,” a legendary gunslinger. He returns with the muscle memory of a master marksman and a 12-gauge shotgun. World 2: The Martial Arts Realm. He trains for decades as a Wuxia disciple. He returns with internal energy that can shatter steel.Now, as the Kingdom faces war and monsters surge from the dark, the nobles sneer at the servant boy holding a strange metal tube. They chant spells. They draw enchanted swords. Kael takes a slow breath. He racks the slide. Click-clack. “Parry this.”

After the nuclear war, the world was controlled by twenty mega-corporations that established a global government. Governed by AI, it judged everything.Gao Xin, who had only wished to live a peaceful life, inexplicably became a scapegoat for the elite and, unable to pay the imprisonment fee, was sentenced to ten years of exile on Crime Prison Island!On this island, there were no laws, no constraints, the only order being the numerous game arenas set up by the officials.The criminals could only participate like racehorses for the entertainment of the elite.Yet, on this prison island filled with Radiation, cyborgs, and many powerful villains, Gao Xin had no strength, no talent, and no background—like a sheep thrown into a crocodile pool, no different from being on death row.How could an ordinary person like him survive under the oppression of the strong, the geniuses, and the wicked? Unless in this world, there was a path, a path that allowed even the weakest to continuously break their shackles.

In a world where dungeon runners rise to fame by mastering their classes and conquering impossible threats, Alexander was never meant to be part of it. No class. No path. Just a quiet life.When a mysterious portal drags him into a hidden realm known as his Inner Path, Alexander unlocks a class no one has seen before: Beholder. There’s no fanfare. No guidance. Only eyes that see too much, and power that threatens to unravel his mind with every use.Now, trapped in an abyssal dungeon that reshapes itself around eldritch laws, Alexander must survive alone.But with each victory, his vision sharpens. His spells twist reality. And the deeper he goes, the more the world outside should start to worry.Because when he returns-They won’t be able to look away.

A scientific genius named Thomas Harrier was transmigrated to an imperial prince body after a car accident that took his life. He found out that he is in a world similar to our own with a timeline akin to early twentieth century. The body that he is occupying was the imperial prince of a failing empire who suddenly rose to power after a successful assassination attempt of his father. Unaware that the attack is just the beginning of what is to come. He faces many challenges throughout. Will Thomas Harrier be able to live his second life in peace while running an empire and getting it back to its former glory?
