The Greatest Sinner

"He has the title of Baron, and he also evolved once? How strong is he?" Asked Evan.

"My brother is in the - Two-Pointed Star stage without flames, but he can easily fight three mages who have one flame each and defeat each of them. None of you are his adversary, when my brother gets here, it will be, of course." Proclaimed Nessa.

"That does sound formidable, however, apparently, your brother won't make it in time. I doubt the vampires will last long without your support, but even if you were with them, it wouldn't make a difference. You need help, and I will give it to you. My condition will be that your brother provides me with as many blood magic spells as possible. I don't need anything else." Evan said calmly.

"Okay, if you help us, I'm sure your brother will provide you with enough blood magic spells." Said Nessa..

"The only question left to decide is, how can I trust you? If you betray me, I could easily kill you, however your brother will not let me do that. What do you say? Should I kill you right here and now?"

Evan understood that Nessa had no reason to keep her word. She could have taken advantage of Evan and just betrayed him, nothing was stopping her from doing that.

Nessa understood that as well. Her spatial ring glowed, and a parchment scroll appeared in her hands.

"This is the scroll of the spell, the Bloody Agreement. We can use it to make sure we each keep our part of the bargain." Nessa said calmly.

"How does it work?"

"We leave drops of our blood on this spell, then activate the scroll. Then, we each say our terms, after which the agreement is made. If one of us doesn't fulfill the oath, he or she will die instantly."

"Hmm, how much does your brother care about you?" Evan said coldly.

Evan will get his reward not from Nessa but her brother. That means that if Nessa's brother doesn't care about her, he'll just let her die and kill Evan in addition to it.

Nessa frowned and said grudgingly, "All vampires hold their bonds very dear, especially family bonds, trust me. If that's what it takes, my brother will destroy an entire town for me."

Evan stared at Nessa intently. He was trying to figure out if the girl was lying or not.

Evan nodded and said, "Okay, I agree."

The next moment Evan bit his finger, and his drop of blood fell on the scroll. Nessa did the same, then activated the spell scroll.

A magical red circle appeared above the scroll, from which a scarlet thread flew out. It penetrated Nessa's heart and Evan's heart. They were joined, and now it was time to make their vows.

Nessa began first, "I am Nessa Emerton, I swear that if this man helps me protect my comrades and kill my enemies, he will receive many spells of blood magic from my brother and be our friend."

She decided to do just that so that Evan would have no doubts about the purity of her intentions. Now, if Nessa chooses to betray Evan, she will receive a death sentence. In that case, once the pact is fulfilled, neither Nessa nor her brother will be able to attack Evan.

Evan nodded, "I am Evan Lynch, I swear that I will destroy all of Nessa Emerton's enemies in these mines."

After they said their vows, the scarlet thread split in two and wrapped tightly around their hearts. If either of them broke their vows, the thread would constrict and instantly crush their hearts.

"Great, now it's time to go back. You must attack the group of mages from behind, they must not escape me. Moreover, you must warn your comrades not to attack me or come close to me. Otherwise, they will all be burned to the ground." Said Evan.

Nessa nodded and ran forward. She didn't know what Evan was going to do, but he sounded extremely convincing. Moreover, after Evan had made his oath, Nessa became fully convinced that Evan had a way to kill all the mages in those caves.

He frowned and slammed his fist into the wall with all his might.

"Damn! I didn't want to do that. It gave me goosebumps. How long has it been since I last did this?" Mumbled Evan slowly heading toward the main room.

Nessa had already told all of her comrades not to touch Evan and to run away from him. She cast her spell, and while her comrades ran away and took Laila to safety, she restrained Bas and the others.

"Shit! We need to get through these stakes! Did that guy really lose?"

Bas knew that Evan was two flames weaker than Nessa, but he didn't think the girl could beat him without getting seriously hurt. The others frowned and tried to make their way through the hail of bloody stakes. They thought the vampires had decided to run away, and so all but Nessa retreated.

By then, Evan had reached the battlefield. He was standing in one of the tunnels and was barely visible in that area.

He bled himself slowly and began to draw the demon's sigil on the ground. Evan had used the power of demons in this world many times before, but now he was really disturbed.

Evan wasn't afraid of the price the demon would demand. He was mentally prepared for what would happen after that. Evan was willing to pay even 200 years if it demanded it. Not only did he want to get blood magic spells, but he also wanted to learn about the power of vampires.

From Nessa's words, Evan understood that a vampire noble who had survived evolution was stronger than most mages of the same rank. Such power couldn't help but appeal to him.

He looked at Nessa and, realizing that he couldn't wait any longer, decided to activate the sigil.

Evan said quietly, "Sigil of the 68th demon - King Belial, activation."

The next moment Evan's consciousness was transported to Nirvana, where the demon he had summoned was already waiting for him. It was a tall man with waist-length hair. His red hair burned with a bright flame that could burn anything. His skin was pale, and his eyes were cold. His face looked as if he wanted to enter eternal sleep. 

The most notable detail of his appearance was the four angelic wings. Two of them were snow-white, and the other two were dark as the abyss. All four wings burned with a crimson flame.

Evan said, "Give me the power to incinerate everyone here. Not even ashes should be left of them!"

The demon nodded lazily and said, "You're pretty interesting. I'm curious to see what happens next, you must offer me a sacrifice equal to 100 years of your life."

Evan nodded confidently, and flames from the demon's wings headed towards Evan. This flame did Evan no harm, but it burned away his life force. At the moment, Evan's life span was 422 years. After a couple of seconds, it would be reduced to 322 years.

Evan knew the sigils of 72 demons, and the higher the demon's position, the stronger it was. This rule worked without exception, but between some positions, there was an incredible difference in strength.

The destructive power of the 69 demon Marquis Decarabia and the 70th demon Prince Seere differed from each other, but not fundamentally. Moreover, Prince Seere's spear could be even more useful than a single destructive blast in some situations.

However, the demons with King status were somewhat special. The power gap between the 68th demon King Belial and the 69 demon Marquis Decarabia was unimaginable. For the same reason, the price was much higher. What's more, Evan was only using the first level of the sigil. The higher the sigil level, the more significant the difference between the Kings and the rest of the demons.

When the procedure was over, and Evan sacrificed 100 years of his life, he gained the power of a demon. Before he disappeared from Evan's Nirvana, King Belial gathered all his flames into a small blob and directed it toward Evan.

The blob of flame slowly flew toward Evan and penetrated his chest. The next moment Evan's appearance began to change rapidly.
