Black Cross: The Blood System
Adrian Azuma was an ordinary high school teacher with a quiet life and a loving wife until a vampire took everything from him.
When Sarah is murdered, the authorities dismiss her death as a tragic accident. But Adrian soon discovers the horrifying truth, vampires secretly live among humanity.
Desperate for revenge, Adrian is recruited by Lirielle, an elite vampire hunter and member of the mysterious organization known as Black Cross. Determined to find the vampire responsible for his wife's death, Adrian joins the organization and begins his brutal training.
Then, after killing his first vampire, something awakens within him.
A mysterious system.
> The more vampires you kill, the stronger you become.
Every kill rewards Adrian with Blood Points, allowing him to enhance his physical abilities beyond the limits of an ordinary human.
By day, Adrian returns to his life as a teacher, hiding his new identity from his students and colleagues.
By night, he becomes Shadow, a Black Cross hunter hunting Vampires that lurk among humanity.
But ordinary vampires are only the beginning.
As Adrian grows stronger, he discovers that the supernatural world is far more dangerous than he imagined and that the system may have a purpose beyond simply making him stronger.
He wanted revenge and the System gave him power.
But how much blood will Adrian have to spill to uncover the truth?

Chapter: CHAPTER 44 — THE LADY'S NIGHT OUTShe walked into the bar, and the sensation of bright lights and sounds hit her all at once.Loud music boomed from the speakers, and colourful lights illuminated the crowded room filled with people.She was wearing a face cap, a jacket, trousers, and sneakers for comfortable walking as she entered and approached the bartender.She walked to the seat in front of her and sat down, holding her nose to avoid the smell of alcohol and cigarettes. People were everywhere, on the dance floor, at tables, and on chairs, laughing, drinking, and having the time of their lives.She was sitting at the long bar counter where the bartender usually mixed drinks and slid them across to customers.“Good evening, ma'am. What can I get for you?” the bartender asked as he approached her.“I'm in the mood for something new, so I'm going to ask for your recommendation. Surprise me,” she replied, and the bartender smiled.“I'll do as you've requested,” he said and walked away.She watched the bartender mix mul

Chapter: CHAPTER 43 — A BEAUTIFUL NIGHT TO GET INJUREDCHAPTER 43 — A BEAUTIFUL NIGHT TO GET INJUREDThe first thing Adrian saw when he opened his eyes was the night sky. He took a moment to stare at the multiple glowing stars high in the sky.The second thing he noticed was the pain. His entire body ached, and even the simple act of breathing felt slightly uncomfortable. He tried to sit up, but a sharp pain shot through his side, forcing him to lie back down.“Fuck…”He stared at the sky, waiting for the pain to settle. He looked down at his body and soon noticed that he wasn't bleeding at all.The System had healed him once again, preventing him from dying of blood loss.“Why did I even pass out in the first place?” Adrian asked himself.Was it because he was exhausted from his fight against those vampires?Was it because he had been beaten, injured, and lost too much blood?He couldn't seem to find the right answer and soon scrapped the thought. He was alive, and that was all that mattered.Then he noticed someone lying beside him. Gol

Chapter: CHAPTER 42 — A DIFFERENT PAIR OF EYESLirielle’s POV“This place is our mission, and everybody in this restaurant is a fucking vampire!”I stood on the table, pointing at Adrian with one hand while holding my empty glass in the other.For a few seconds, the entire restaurant fell silent as he stared at me as though he had finally realized his senior had lost her mind.Well, the Korean barbecue had been excellent, and Adrian had turned out to be surprisingly entertaining company, but we had a mission to complete.A man sitting at the next table slowly turned his head toward me, his eyes glowing red. Another customer revealed his fangs, followed by the woman sitting beside him. Within seconds, the entire restaurant changed.Red eyes gleamed beneath the lights, fangs extended, and sharp claws emerged from fingers that had been holding chopsticks moments earlier.“Holy shit!” Adrian muttered as he reached for his gun.He began counting the vampires but stopped halfway through.“Lost count already? And we haven't even reached

Chapter: Chapter 41 — A DIFFERENT PAIR OF EYES.Lirielle's POV“Cheers!” Lirielle said as she clinked her glass against Adrian's before tilting her head back and gulping down the entire beer. She wiped her mouth with the back of her hand, then reached for another drink.Across from her, Adrian took a more modest gulp before setting his glass down.Not bad, Adrian, she thought to herself. At least he knows how to enjoy a night out.They were sitting in a Korean barbecue restaurant late at night, surrounded by the sounds of conversations, laughter, clinking glasses, and music from a live band.A small gas grill sat in the center of their table, where thinly sliced beef, pork, and other meats cooked over the low flames.Lirielle watched Adrian carefully place another piece of beef on the grill with his tongs.He had looked genuinely surprised when they entered the restaurant. Apparently, he hadn't even known a place like this existed in Ashvale. She found that amusing.For someone who spent his days fighting vampires and worrying abou

Chapter: CHAPTER 40 — THE SLAUGHTERHOUSE“This place is our mission, and everybody in this restaurant is a fucking vampire!”Lirielle's voice echoed throughout the restaurant as she stood on the table, pointing at Adrian with one hand while the other held her empty glass.For a few seconds, everybody just watched her, and Adrian acknowledged that she was drunk. However, he immediately started looking at the faces of the people around him, and that was when it hit him.A man sitting at the next table slowly turned his head toward her as his eyes glowed red.Another customer revealed his fangs, followed by the woman sitting beside him.All around the restaurant, the vampires began revealing their true appearances. Their eyes glowed red, their fangs extended, and sharp claws emerged from their fingers.The cheerful atmosphere disappeared in an instant, and Adrian immediately reached for his gun.“Holy shit!” he said as he looked around, counting the vampires as quickly as possible. However, he stopped halfway because there were

Chapter: CHAPTER 39 — A NIGHT OF SURPRISES“Cheers!” Lirielle said as she and Adrian clinked their glass cups together. She then gulped down the entire beer and wiped her mouth.Adrian took a gulp before dropping his cup on the table.It was late into the night, and both of them were at a Korean barbecue restaurant.A small gas grill was built into the center of their table, and the restaurant served thinly sliced beef, pork, and other meats. Adrian placed the pieces directly on the hot grill using tongs.This was a first-time experience for him, as he didn't even know a place like this existed in Ashvale.He watched in amusement as the meat cooked in minutes, while Lirielle instructed him to turn it over until it was cooked to his liking.He had to try different methods before he finally found the perfect timing for how he liked his meat. He then dipped it in a sauce before sending it into his mouth.“This is fucking amazing!” Adrian said as he chewed the meat, rested his back against his chair, and looked up at the ceiling.

Chapter: CHAPTER 55 — THE TRUTH ABOUT THERAPYAdrian walked out of the bathroom with a small towel over his head, already dressed in a shirt and shorts he had found inside the wardrobe.Mina was on the bed, wearing an oversized shirt that covered her from head to toe, with part of it even dragging along the floor.She was playing a children's game on his phone, her attention completely locked in.Adrian walked over to his bag, pulled out the A-Rank Core, and sat on the bed with it in his hands.He had tried to absorb it earlier, but the System had sent him a notification telling him that it was not possible.He later found out that the S-Rank Core he had absorbed was still residing in his body, so absorbing any other core would create a mana overflow, and he would die from mana overload.He didn't know that was a thing until minutes ago.“Papa, hungry,” Mina said as she climbed onto the bed, crossed her arms over his shoulder, and rested her head on his, looking down at the A-Rank Core.“Adrian, the food's ready,” Kellan said fro

Chapter: CHAPTER 54 — THE HEROES OF THE DUNGEONThe moment they all stepped out of the portal and back into the underground parking garage, they were welcomed by different sets of people.From security officers to media personnel, camera operators, and news reporters.Adrian had to shield his eyes as the flashes of the cameras almost blinded him.“From your uniform, you must be a student of Aegis. Please tell us what happened in the S-Rank Dungeon.” A reporter walked up to Adrian, shoving a microphone into his hand while a camera held by a cameraman was pointed directly at him.“Well, it was a horrifying experience,” Adrian started as he straightened himself.“There were monsters everywhere, and me and my summons couldn't keep up. I would have died in there if not for the help of those brave heroes.” Adrian said, pointing to Scar and his Guild members as the camera turned in their direction.“They saved me and my family. They worked hard in unity and killed the Dungeon Boss. It was a rough fight, and I wanted to join, but they told

You are a good girl,” Adrian said as he patted her green skin with a satisfied smile on his face.Valeria seemed to be enjoying it too much as she rubbed her head against Adrian and even pushed him, making him fall softly onto the ground.“Thank you for your support today, Vale. You did good,” Adrian said, patting her nose one more time before turning and walking up to Kellan.“It sure is wonderful to have a dragon as a summon, am I right, Kellan?” Adrian said, patting his shoulder as he kept walking.“Now I'm wondering if you're the summoner or I am,” Kellan grumbled as he followed Adrian.They walked up to where everyone had gathered as the battle had ended, and they all regrouped.Most of them were alive, with the majority injured. All of Adrian's Knights were gone

Chapter: CHAPTER 51 — THE DUNGEON BOSS“So how are you boys going to reach the Dungeon Boss?” Kellan's mother asked as she approached both of them.“We'll ram straight through the army. I'll tell Strix to keep an eye on us and shoot down anyone that tries to intercept us,” Adrian said, and Kellan nodded.“I’m fine with that,” he said, but his mother suddenly grabbed his hand, making him turn to look at her.“You have to bring her out,” she said, holding both of his hands.“No, there’s no way I’m…” He didn't finish his words as she cut him off.“You see what your friend is doing. You see how he brought out all three of his summons and even brought out a whole army. He would be in so much trouble if word about this gets out of the dungeon, but he’s doing it anyway. The least you can do is fight with your full power too. Please,” she begged him as he stared into her eyes for a few seconds before nodding his head.“You ready?” Adrian asked as Kellan walked back to him.“Nah, I've got a better option,” Kellan replied as the are

Their strategic positioning and attack potential were insane.If The Council ever learned the full extent of Adrian's abilities, they wouldn't leave him alone.“Boss, what are we looking at?” one of Scar’s teammates asked him.“We are looking at a miracle, and if by any chance he is killed, then we have lost our only way out of this dungeon,” Scar said and walked up to Adrian.“We’re going in now, so cover us.”Adrian just nodded his head and turned back to face the battlefield.The dungeon car raced through the battlefield, dodging the Centaurs by swerving left and right.One Centaur jumped high in the air, ready to smash the incoming car, but a red arrow pierced its head, killing it instantly before it touched the ground.The only people remaining at the base were the civilians, Adrian, Kellan, Kellan’s mother, and Mina, who was holding the hand of Kellan’s
