After choosing to leave, they regretted it.

Pursing his lips, he sat back in his seat dejectedly.

The atmosphere fell silent for a moment.

After half a minute, Aize coughed dryly, intervened and changed the subject.

"Let's not talk about this anymore, Charlotte. How much do you know about this incident?"

As one of Aize's most critical informants in the demon clan, Charlotte has been providing him with various intelligence for a long time.

Including the previous battle in which the Silver Star team ambush the vampire ancestor, the initial source of information also came from her.

Therefore, Aize trusts her very much.

And because of this, from the moment he learned about the blood plague, Aize has been doubting whether this incident is really as simple as it seems.

After all, it was very unusual that Charlotte had no news about the vampires' actions.

In response to the question, Charlotte put away her sarcastic smile and shook her head:

"Not much, unfortunately."

"Oh?"

"What is certain is that this attack has nothing to do with the vampires."

Hearing this, Heidi raised her head again, staring at the other person, and shook her head in complete disbelief.

"It has nothing to do with you? But besides the vampires, who else could spread the blood plague?!"

"What a nagging little girl! Not only do you not repay a favor, but you don't even have the patience to listen to what others say. This is your city, so what if I just leave it alone?"

"you--"

Heidi was speechless.

The black accounts related to Aize in the past were cut off, and no matter what the other party said, he could only bear it.

Only at times like this did she really wish she could go back to her shameless state more than a month ago and have a good fight with this guy.

Of course, there is no such possibility.

Charlotte continued:

"The previous vampire ancestor just died, and then the Great Witch and the Orc Chieftain were killed in quick succession. Both the witch and orc armies were severely damaged. The Demon King is already in a state of panic. How could he act so quickly?"

Aize nodded slightly.

This was partly what he expected.

Even if it weren't for this, he wouldn't have dared to abandon Tafia and come all the way here.

"So, what's going on?"

"You know, the so-called True Ancestor of the Blood Clan who was killed by Silver Star before, in terms of relationship, he is my brother."

Aize nodded.

"Ok, I know."

For the vampire species, the main way of reproduction is blood donation.

That is, injecting one's own blood into humans or other races for transformation.

Therefore, the blood ties and kinship of vampires are very different from those of humans.

The first vampire, the true ancestor of the vampire clan, died in the civil war among the demons hundreds of years ago.

Afterwards, the title of True Ancestor was passed down among the first generation of descendants who were directly converted by him and those who directly gave birth to him.

Charlotte was born as a vampire, while the previous True Ancestor was transformed.

So, as a backup of the vampires, he is indeed Charlotte's brother.

In fact, from a human perspective, it is difficult to define this relationship in this way.

There is no emotion at all.

"That guy is dead, and the new True Ancestor has not yet been determined. But if nothing unexpected happens, I will most likely take over. After all, there are only a few people left in the pure-blooded True Ancestor's bloodline."

Charlotte paused, then tapped the table lightly with her fingers.

"And the premise of all this is that my bastard brother must die completely, and that's exactly the problem."

The vampire girl had an unusually serious expression:

"About twenty days ago, when I was sorting through his belongings, I discovered that a can of blood that was supposed to be kept in the secret room of the City of Eternal Night was missing."

Chapter 61 I was obviously the one who came first

Among vampires, there are huge physiological differences between high-level and low-level ones.

Low-level vampires, apart from having relatively good looks and their brains not being burned by bloodthirsty desires, are actually not much different from blood slaves in terms of abilities.

High-level vampires, on the other hand, were something completely different.

These extremely ancient beings who like to consider themselves aristocrats have a glamorous appearance, but their true essence is actually their blood.

Consciousness, memory, power, magic, personality, etc. all depend on blood.

As long as the blood remains, no matter how much damage is done to the body, it cannot be completely eliminated.

Even in historical documents, there are examples of high-ranking nobles whose bodies were completely destroyed, and who were reincarnated by taking over the bodies of other people through blood. It can be said to be quite troublesome.

Therefore, Aize would even jokingly call these guys blood slimes in private.

Of course, Charlotte must not hear this, otherwise she would most likely be caught and bitten on the neck.

For this reason, when guiding the Silver Star team to fight against the True Ancestor of the Vampire Clan, Aize asked them to use the power of the Holy Sword to completely burn the battlefield after the battle, leaving no drop of blood.

In contrast, in order to deal with such extreme situations, some high-level vampires will keep some of their blood behind for emergency use.

The small amount of blood separated from the main body cannot carry the complete will and personality.

Even if regeneration is eventually completed, it is hard to say whether the final entity will be the same.

So not all vampires do this.

For example, Charlotte.

In her previous words:

"I've lived long enough. Death is fine as sleep. The thought of creating a half-baked thing that looks good on the outside but has no idea what it is inside is disgusting."

But the previous generation of vampire ancestors obviously had different ideas.

Before being destroyed, he preserved his own blood in order to be resurrected in another form.

After successfully killing the True Ancestor, Charlotte said not to worry about it, she would take care of it.

Unexpectedly, something went wrong.

"A jar of True Ancestor's blood, that's really troublesome."

Aize sighed softly and rubbed his eyes again.

As mentioned earlier, the magic spells mastered by high-level vampires will also exist in the blood.

And the previous True Ancestor happened to be the one who improved the blood plague technique.

If this guy's blood were to spread among the crowd, it would really cause a big mess.

"How did it disappear? Was it stolen? Or was it taken away by someone from the True Ancestor's faction?"

Charlotte shook her head.

"I'm not sure. The guards in the secret room are clueless. But according to the relevant records, the blood bottle may have disappeared before my bastard brother died."

"……what?"

Within the vampire clan, supporters of the previous true ancestor stole the blood in order to resurrect their own boss.

This is the most plausible general explanation.

However, if someone really took it away earlier, then something is wrong.

The motives of the guy behind the scenes may be more complicated than expected.

"So, I checked all the records for the past two months, and sure enough, I found some problems."

The burgundy-haired vampire girl tilted her head and continued.

"Two weeks before his death, a batch of unidentified items was sent from the City of Eternal Night to the Kingdom's territory. I suspected it was related, so I personally led a small team to investigate."

"Because there were no leads and you were also out of contact at the time, I had no choice but to start my investigation in the capital. As a result, just three days after arriving here, the blood plague broke out."

Charlotte smiled bitterly and spread her hands:

"Not only did I fail to obtain crucial intelligence, but because those impolite human nobles set up detection barriers outside the city specifically targeting vampires, I was even trapped here and couldn't leave."

After all, the Duke Alliance is unaware of this relationship.

To block the blood plague, it is natural to make special arrangements targeting the vampires.

The blockade line built by more than 100,000 elite human troops is not a situation that Charlotte can break through alone even without a brave man.

As a result, he was caught in the crossfire.

That's why Heidi was sent to deliver a message to Aize.

From a big picture perspective, if she actually told the truth directly, Heidi would not refuse to listen.

Out of a mixture of anger and jealousy towards Eze's former teammate, Charlotte would rather make things a little more complicated and give her a hard blow.

So he taunted me in the face.

Just fuck Heidi until she breaks down.

That’s how the following events happened.

The causal relationship between these two is quite funny to think about.

Aize glanced at Heidi, who was silent beside him, and continued to ask without saying anything more:

"What else? Have you found anything valuable in all these days here?"

Charlotte pulled a small, delicate glass bottle from her pocket and placed it in the center of the table.

In the glass bottle, there was a dark red turbid liquid floating, and an ominous faint black color like mist, slowly spreading around.

Aize picked it up, looked at it, shook it, and frowned:

"This is?"

"The blood samples collected from the blood slaves in the royal capital do show signs of contamination by the blood plague. However, it is different from the blood plague created by my brother."

Aize raised his eyebrows slightly:

"What's the meaning?"

"Compared to that guy's version, the infectiousness and infection speed are almost doubled, and the blood slaves' aggressiveness has also been greatly increased."

"In other words, someone has improved upon the original Blood Plague?"

Charlotte supported her chin, narrowed her eyes slightly, and had a subtle expression on her face.

"Besides being destructive, the blood slaves are completely uncontrollable. Even I would be targeted. Their blood is awful and unfit to drink. Improvement? Is this considered improvement?"

The original blood plague is a natural disaster for humans, but a useful weapon for vampires.

In addition to killing a large number of people, the transformed blood slaves will not attack the vampires, and can even be controlled to a certain extent and further participate in the battle.

After losing their combat value, they can be recycled and used as food for low-level members of the vampire clan.

These properties are the product of a high degree of balance and consideration.

Putting aside his stance, the previous generation of vampire ancestor was indeed a genius in this regard.

The blood plague that is now occurring in the royal capital has transformed from a war tool into a purer disaster.

Charlotte was of course very disdainful of this.

And Aize fell into deeper doubts.

"Who do you think did this analysis for and why?"
