The Heroine is My Stepsister, and I'm her Final Boss - Chapter 19: Humanity.

Is Magic really just a wish machine? No! In a universe where Magic truly exists, the ultimate nature of Magic must be as simple and aesthetically pleasing as the laws of physics. This is the story of a mass-produced magical war tool who learned the ultimate nature of Magic. But what of it? Just as birds can fly without understanding aerodynamics, magicians can use Magic without grasping its ultimate nature. Learning the ultimate nature of Magic doesn’t mean the tool can instantly transform into a great magician. But yearning for knowledge is a human instinct, and curiosity is the primary driving force of human civilization. Even for Magic, which should seemingly defy explanation, humans hope to understand its inherent operational laws. The pursuit of Magic’s ultimate nature requires no reason! The story in this book takes place in an era where steel and gunpowder dance together. Here, firearms are on the rise; armor remains the main character; military theory is changing rapidly, with endless innovations in systems and techniques. And this world has something more than ours: Magic. The world is undergoing a profound transformation, and no one can remain detached from it...

This allows him to absorb essence, enhancing gear, gaining stats and EXP from slain creatures, and crucially, absorbing attributes and skills from fallen Awakened.Witnessing the swift death of the arrogant Jaxon Rex, Daniel makes a grim choice: he assimilates Jaxon, gaining his first skill, [Kinetic Pulse]. This sets his path: scavenging the aftermath of others’ battles. He enhances gear and, after achieving his first kill on an injured beast, waits patiently to assimilate two more fallen recruits, acquiring [Quick Step] and the invaluable passive [Aura Sense].Starting as average, Daniel rapidly gains power in secret, enhanced gear, multiple skills, and boosted stats , far exceeding his peers while remaining outwardly unremarkable. He navigates the lethal Verge alone, using its inherent dangers to fuel his growth, wrestling with the moral cost of his unique, overwhelming power.
