Infinity: Kill your way through the movie world.

"Third, this isn't like taking drugs to instantly become a superman. Enhancement is progressive, and every power comes at a price."

"You need to get an injection once a month for 10 consecutive months. Each time is a brush with death. Only by enduring all ten injections can your body and soul begin to stabilize and reach what we define as 'devil level'!"

David used this to introduce a new power system for the guild:
"According to the new rules set by the guild leader, demon hunters are divided into beginner, intermediate, and senior levels. 'Demon level' is a level above senior. It means that with your own strength, speed, reaction, or a certain awakened ability, you are enough to face or even kill ordinary demons head-on. With the weapons and items provided by the guild, your combat power can increase exponentially, making you absolutely superior to ordinary demons!"

The tent was deathly silent.

David's realistic words tore away all the warmth, leaving only naked and cruel choices.

A few seconds later, an old witcher with a scar on his face broke the silence, his voice rough: "Stop babbling, David."

"I've driven out more demons than any of you young people have ever seen. I've had my fill. Being able to personally twist off more scum heads and completely kill a few more, what's a little bit about being childless? I'll take this shot!"

"If becoming a ghost can tear those disgusting guys apart, then I wouldn't care even if I became a ghost."

“Count me in!” A young female demon hunter stepped forward, her eyes sharp. “My sister died at the hands of a demon. I want the power to avenge her with my own hands!”

"In order to survive, in order to be able to"
"Protect more people!" another voice rang out.

No one moved an inch to leave. Those who came here were selected through big data screening and signed up voluntarily.

They looked at each other and saw the same thing in each other's eyes: the determination to fight the darkness to the end, and the resolve to step into the fires of hell and become a demon in order to tear the enemy apart.

"Alright!" David said in a deep voice, "Medical staff, prepare for the injection!"

The process of injecting the medication into the vein was not pleasant.

After the sharp, stinging pain comes an even more painful internal upheaval.

The tent was soon filled with various sounds: suppressed growls squeezed from the depths of the throat; teeth-grinding 'clucking' sounds from muscle fibers tearing and rebuilding, and bones being forcibly stretched and modified; and various colored glimmers of energy of different attributes awakening for the first time and overflowing uncontrollably.

"Iron Wall" Mark, the burly man sitting in the second row, let out a roar like a trapped beast. His already exaggerated muscle size expanded again, and his skin darkened, showing a dull, metallic sheen, as if an invisible armor was naturally covered under his skin.

He tried throwing a punch into the air, and the wind pressure generated by his punch made the tent curtains flutter loudly.

'Spirit Fox' Liz has become even more agile and nimble, her movements carrying a feline elegance and explosive power.

Her pupils briefly turned into sharp vertical pupils when the light changed, and her dynamic vision became extremely terrifying, even able to catch the afterimage of bullet trajectories.

She whispered to her companion beside her, "I can see the dust particles dancing in the air—no, it's residual energy!"

The silent hunter, known as Old Smoker, habitually lit a cigarette. The smoke he inhaled seemed to resonate strangely with the potion in his body, and his breath was scorching hot. His fingertips unconsciously moved in the air, creating a tiny spark that singed his own eyebrow, making him pause for a moment.

Meanwhile, another tracking expert, codenamed 'Hound,' twitched violently, his face showing a mixture of pain and excitement. He quickly covered his nose, then his face contorted with the stench of his hands from scratching an itch.

"There's so much of a smell—sweat, blood, fear, and... metal, fire? All sorts of strange smells. I can even 'smell' which of you was scared just now!"

"And f***ing, old smoker, your breath stinks so badly! Can you please stop blowing smoke rings that smell like bad breath and ketchup? Ugh!"

Many people experienced a comprehensive leap in physical fitness. Those with increased strength easily bent metal bed frames; those with increased speed nearly crashed into tent poles; and those with self-healing abilities showed that shallow scratches on their arms healed at a visible speed.

However, this method of acquiring power naturally comes at a price.

A scream, completely inhuman and filled with violence and pain, came from the corner of the tent.

A witcher's eyes were instantly covered in pure black, his nails turned black and long, and his mouth split open to reveal fangs as he frantically pounced on the nearest companion.

"He's out of control! Suppress him!" David shouted, his voice booming like thunder.

Sam and Dean, who were standing by, acted swiftly.

With Sam's current ability to fight a group of demons, this mutated, corrupted witcher had no power to resist and was choked in mid-air.

The demonic power acts even more directly on a deeper level, completely gripping the soul!

The nearby witcher squad, using a specially formulated high-strength sedative and a binding net mixed with black silver fibers, swiftly and cleanly subdued the out-of-control individual who had completely lost his mind and forcibly removed him from the scene.

His fate was sealed.

Almost simultaneously, another witcher clutched his head, letting out a piercing scream of mental collapse. The blood vessels under his skin bulged and writhed like twisted earthworms, and energy surged wildly within his body.

"Keep him calm! Mediums!" Dean shouted.

Sarah immediately led her team forward, chanting ethereal and ancient requiem incantations. Combined with potent sedatives, a soft white light enveloped the witcher, barely pulling him back from the brink of complete collapse.

However, his face was pale and his eyes were unfocused, clearly indicating that he had lost the qualification to continue strengthening.

Of the fifty people, two lost control, one was on the verge of a mental breakdown and withdrew, and forty-seven successfully passed the first enhancement.

The tent was filled with the smells of sweat, blood, the bitterness of medicine, and the restless, burning heat of a new life force.

The successful individuals, some sitting and some standing, were breathing heavily, feeling the unfamiliar yet surging power within them. Their eyes held a mixture of extreme exhaustion, the relief of surviving a close call, and an barely suppressed excitement at finally being able to take control of their own destiny.

After several hours of mandatory observation.

After basic data collection and simple power control guidance, the forty-seven newly enhanced demon hunters received their first practical test mission: to wipe out a group of red-eyed demons that, according to the guild's intelligence network, were lurking in an abandoned iron mine in a neighboring state.

The estimated number of demons is between thirty and fifty.

There was no rousing rally, only a mission briefing and weapons inspection orders thrown at him by Jack.

Night is the best cover.

The convoy stopped a mile from the mine.

The once-unbreakable Mark, feeling the surging power within him, volunteered: "I'll open the door." (End of Chapter)
