Hitman with a Badass System

After killing every single vampire except Zarathor, Michael had finally reached the Fusion stage to become the youngest cultivator to reach the Fusion Stage. No one in the entire world achieved such a humongous feat, not even Laila or Victoria, the princess of Thusia. By reaching the Fusion stage at a young age, Michael sealed the chance to become an Immortal in the future. However, nothing was in his mind at that moment except killing Zarathor and making him pay for what he did to Sabrina.

To be honest, Michael had never felt such anger ever before in his life. Not even when Spectre and his students killed everyone in Michael's orphanage back on earth. When he sensed Sabrina's heartbeat stops, his anger exploded within him.

Zarathor may have stood a chance against the Dark Lord when Michael was at the Soul Refining stage. Now, he was like a lamb waiting to be slaughtered in front of Michael. Michael released all the fear toxin stored in the microtubes within his armor as the fear toxin slowly entered Zarathor's bloodstream. In addition, Michael used everything to boost his strength.

"The Dark Lord," Zarathor mumbled under his breath as fear slowly clasped his heart.

"You just sealed the fate of your kind," Michael threatened Zarathor.

Instead of dashing at Zarathor using his Lightning Dash spell, Michael slowly stepped toward him.

"Blood Beam!"

"Rage Chakra!"

"Life Sucker!"

Zarathor cast spell after spell to stop and kill Michael, but Michael deflected the spells using the Ghost shield and Responsive Shield. Of course, some of the spells hit Michael and made him bleed, but he was too furious to feel any pain.

As the Dark Lord approached Zarathor, the latter stopped casting spells that would take too much time to cast and began to cast quick spells. At that time, Michael was bombarded with arrows made of blood shooting out of Zarathor's arms. Although the responsive shield couldn't stop the arrows completely, it absorbed most of the arrows' energy and made them weak. Thus, the arrows that escaped the Ghost shield grazed Michael. As a result, he has multiple cuts and bruises on his body.

Ding!

One of the arrows hit Michael in the face and took a piece of his skull mask, leaving half of Michael's face exposed. Despite everything, Michael approached Zarathor under the rain of arrows. Hundreds of arrows rained down on Michael from all directions. If the spell was cast on someone else, they would have been skewered by the arrows and turned into a bloody mush.

The power of a Fusion stage cultivator was not a joke as even the weakest combat spell would be deadly when a Fusion Stage cultivator cast the spell.

Under the rain of arrows, Michael finally arrived in front of Zarathor and grabbed him by his neck. Now the tables were turned as Michael squeezed Zarathor's throat. Next, Michael raised his other hand, pinching Zarathor's fang. The vampire squirmed violently as Michael pulled out his fang with his bare hand.

"ARGH!"

Zarathor frantically squirmed in Michael's hand. The vampire couldn't scream out loud because Michael's hand was around his neck. Otherwise, Zarathor's scream would have echoed through the dungeon. While Zarathor was squirming in agony, Michael pulled out his other fang.

Bang!

After pulling his second and last fang, Michael punched Zarathor right in the mouth, breaking all of his teeth.  Typically, Michael would have interrogated the vampire to know the location of their headquarters, more information about the key, and who sent them all. However, at that moment, Michael wasn't in the mood for interrogation but torture. Still, a corner of his mind told him to take the ring in Zarathor's hand.

"ARGGHHH!"

Instead of removing the arm, Michael broke Zarathor's middle finger and ripped the finger clean off from his hand. Michael then stored the bloody finger in his system storage before throwing Zarathor to the wall on the other side.

Bang!

Zarathor went flying to the wall like a kite without an anchor. The fear toxin made thinking difficult for Zarathor. His mind was in a boggle as Michael raised his hand towards the Doom Bringer which lay on the ground several meters away from him.

He controlled the wind element surrounding the Doom Bringer and made the war hammer fly into his arm. Michael stepped on the vampire between him and Zarathor, crushing the vampire's head under his feet.

Granted, the dungeon was usually dark and gloomy. Still, it had never been dark and gloomier than at that moment when Michael approached Zarathor with the Doom Bringer in his hand.

"Teleport....teleport...teleport me away..." Zarathor screamed in his mind, but nothing happened no matter how many times he ordered his minions to teleport him away.

He quickly raised his arm to cast a spell,

"Blood-"

However, his spell casting was abruptly cut short as a bolt of lightning went straight through his shoulder.

"Bloo-'

Another lightning bolt went through another shoulder, cutting his spell casting short.

"Wait...listen-"

Zarathor tried to escape the Dark Lord's wrath by striking a deal with him. But, of course, it would have worked if Zarathor hadn't forced Sabrina to kill himself.

Boom!

A powerful gust of wind blasted Zarathor against the wall on another side.

Bang!

Zarathor hit the wall, but before hitting the ground, another gust of wind blasted him to another wall. The Wind blast turned Zarathor into a rag doll, flying around.

The wind blast powered by Celestial energy and Dark flames had enough force to break many of Zarathor bones in his body. When Zarathor finally hit the ground after getting blasted into the walls like a doll, his right arm and left leg looked crooked.

If it wasn't for the vampire's ability to regenerate, Zarathor would have died by now. However, his healing ability was interrupted by the Dark Flames mixed with the wind blasts Michael sent in his direction.

Michael noticed the cuts in Zarathor's body slowly closing up and conjured a ball of dark flame in his hand. Zarathor felt a chill looking at the dark flames dancing above his hand. In his two hundred years of life, he had never seen such a powerful ominous flame.

"No healing," Michael sent a blast of dark flames, scorching Zarathor's clothes, and skin. The strong stench of burning skin would nauseate anyone who takes a whiff of the air in the dungeon.

"ARGHHHHHHHHH!"

This time, Zarathor's scream wasn't muffled by Michael. Thus, his scream echoed through the dungeon halls for miles. The dark flame made Zarathor unrecognizable. His striking red hair was completely burnt by the flame, as well as his black robes. The only thing that kept Zarathor alive and lasted his agony was the regenerative ability of a vampire.

Michael let Zarathor heal a bit so he could inflict more pain on him. Then, on his way to Zarathor, Michael burnt every single vampire on the ground with the dark flames. As a result, the vampires turned into a pile of ashes.

The entire ground was engulfed by the dark flame except for the area around Sabrina's body. He controlled the fire from reaching her as Michael wanted to hand over Sabrina to her family and give her a proper burial.

The vampires were not the only reason for her death. The guardians were just as guilty as the vampires. If it wasn't for them, she wouldn't have been here. The Guardians could have easily come up with another safe plan to get the key with Sabrina's help. Instead, they looked for a quick and dirty way, endangering Sabrina's life. As far as Tanulia and her fellow guardians were concerned, the end justifies the means. But unlike they expected, everything went south, and Sabrina ended up dying.

Michael didn't know about Noah, but he would avenge Sabrina's death...By killing every guardian who knew about Sabrina and whoever stands in his way when he brings down the wrath of the Darkness upon them.

For now, he only focused on making Zarathor pay...nothing more...nothing less.

"Thank you for being the greatest big brother to me..." Michael repeated Sabrina's last words as he raised his hand, making the wind beneath Zarathor lift him up against the wall.

"Will you tell me who sent you here?" Michael asked Zarathor coldly,

"Go...fuck...yourself..."

Zarathor spat on Michael's face, but thanks to the dark flames, his bloody saliva vaporized before it could reach Michael's face.

"It doesn't make a difference. You will suffer the same,"

Michael kicked Zarathor's, shattering his knee and making him collapse down.

"GRHHH," Zarathor growled as Michael put his feet on Zarathor's shoulder and pushed him down while holding his head with his hands.

Michael suddenly shook his head as the skull mask flew away from his face.

"Look at my face," Michael tightened his grip around Zarathor's burnt face.

"This is the face who is going to destroy your kind," Michael pushed down Zarathor and began to lift up Zarathor's head until the head started to separate from his body.

"ARRGGGHHHH!"

The sickening scream of Zarhot reverberated in the dungeon, but there was no one to stop Michael.

Suddenly dark blood sprayed out of Zarathor's body as Michael separated his head from the body with bare hands.

Plop!

Michael kicked down Zarathor's headless body and looked at the severed head in his hand. He raised the head to eye level to see the fear and pain in Zarathor's eyes.

At that moment, every bit of Michael's focus was on Zarathor's head. The world around him just paused in his perspective.

That was the reason Michael failed to notice the slight disturbance in the air behind him.

"Ghost," Michael heard a familiar voice from behind as his body froze for a moment.

But instead of dashing away or trying to disappear from the place, Michael slowly turned around because he knew it was too late to do anything.

When he turned around with Zarathor's head in his hands, he saw Sabrina standing before him. Her white robes were drenched in blood, and the sword was still sticking through her chest. Due to the blood loss, she looked pale, but she was alive as Michael could hear her heartbeat.

"You...you're the Dark Lord,"
