Even with a single drop of blood, I will still be invincible!

"Master, shall we do it ourselves?"

When Brian saw Su Mubai get up, he quickly asked.

"Ah."

Su Mubai nodded slightly and slowly walked up to Brian.

"Have the eligible worlds been selected?"

Before even opening the [Grimoire of Death], Su Mubai had already guessed the conditions for the advancement quest.

Now that he has officially received the mission, things are exactly as he expected.

The number of kills has increased from one billion to a full ten billion, and the strength requirement has also changed from Tier 5 to no less than Tier 6!

It's difficult for one or two ordinary small worlds or planets to meet the requirements for this mission.

To avoid trouble, Su Mubai had Brian select suitable worlds for him to complete his mission from the information provided by Jack and Kilman in advance.

"Master, the selection is complete."

Brian nodded and lightly swung the Reaper's Scythe in his hand.

The next moment, a portal opened beside him.

The color of this portal is clearly different from the previous ones.

It glowed faintly red. Although he couldn't see the scene on the other side through the portal, Su Mubai could feel a chilling aura!

"This world is a bit special."

Su Mubai raised an eyebrow, and golden light flashed in his eyes, as if he had pierced through a teleportation portal and seen the scene behind it.

Brian explained, "The war between the werewolves and the vampires is ongoing, and this secret realm is their battlefield within the Frost Prison God Kingdom."

He paused for a moment, then continued, "You could also say this is a training ground for both races. Anyone who can emerge from this secret realm can be considered an elite!"

"I see."

Su Mubai nodded in satisfaction.

Since it is a battlefield between the two races in the Frost Prison God Kingdom, both sides must have deployed a large number of troops.

Players from both factions who are able to participate in the battle must be quite strong.

This perfectly meets the requirements of the advanced task.

"I'll leave this to you."

Su Mubai patted Brian on the shoulder, and with a thought, directly used soul amplification on him.

In this way, even if he enters the secret realm, he can still use Brian as a transit point to allow the Golden Scourge to continue slaughtering the planets and worlds of both races.

The information about the Soul Absorption effect continued to flood the screen, and the Soul Points in the [Grimoire of Death] continued to climb.

However, opening the [Grimoire of Death] again will require a terrifying 500 trillion soul points, which is no small amount.

However, the werewolves and vampires also wield considerable power within the Frost Prison Kingdom. If the Golden Scourge Legion continues to work hard, they could easily turn the tide once more, or even twice more!

After handing this place over to Brian, Su Mubai took a step forward and stepped directly into the teleportation portal that was faintly glowing red.

……

A secret realm in the night.

This small world is even larger than the Blood Realm Secret Realm.

Furthermore, it was not divided into multiple continents, but rather was a single entity.

It's easy to imagine how big this continent is!

There is no daylight in the Dark Realm; the sky is always a dark color.

Nine silver moons hung high above the continent, bringing a glimmer of light to this dark world.

If this weren't a battlefield between two races, it would definitely be considered a beautiful world.

However, the presence of these two races has left an inescapable stench of blood in the air.

The entire continent is bisected by a mountain range in the center, dividing it into northern and southern halves.

To the south lies the territory of the vampires, while to the north belongs to the werewolves.

The armies of both sides spread out from the central mountain range and extended far into the distance.

Even on their own territories, they could still see many enemies.

It can be said that there is no place on the entire continent that is absolutely safe. Even the headquarters of the two races are often disturbed by the flames of war!

The sounds of roaring engines, fighting, and the clash of metal echoed across the continent.

There isn't a single fancy building here, nor is there any commercial activity.

There were only temporary camps and military achievements!

To survive here, the only thing you need to do is keep fighting on the battlefield.

As long as you have enough military merits, you can exchange them for anything you want!

And you need to exchange military merits to leave this place!

The Dark Realm is nothing short of a meat grinder that's constantly running at full speed.

Every minute and every second, many werewolf and vampire players die on the battlefield.

They couldn't even leave behind a complete corpse.

Vampires who die at the hands of werewolves often have their bodies torn to pieces. On the battlefield, werewolf soldiers can be seen chasing enemies while gnawing on the corpses of vampires in their hands.

Werewolf soldiers who die at the hands of vampires are drained of their life force and turned into dried-up corpses, leaving not a single drop of blood behind.

Despite the vampires' complaints about the werewolf clan's bloody stench, this was a battlefield, and blood was their best source of sustenance.

Sufficient blood supply allows them to maintain peak condition and survive better.

Compared to life and death, they would devour even the most foul-smelling blood without hesitation!

"kill!"

"Brothers, kill vampires, claim the rewards, and reach the pinnacle of wolf life today!"

"Follow me! Killing one is enough, killing two is a huge bonus!"

"There's a ninth-tier mythical-level vampire here. Men, take his place!"

"Hahaha, the military merits we gain from killing him are definitely enough for each of our brothers to exchange for several human blood offerings!"

"Tsk tsk tsk, I want to get a mythical human's thigh. The feeling of roasting it and it sizzling with oil is absolutely amazing!"

……

"You werewolf scum, today is your death day!"

"Pah! The blood of these beasts still stinks so badly!"

"Who says otherwise? If it weren't for earning war merits to exchange for human blood offerings, I wouldn't want to drink the blood of these beasts."

"If I can get out of the Dark Night Secret Realm, I will definitely drink human blood for a whole month!"

"Stop talking! Just thinking about the delicious taste of human blood food makes my mouth water."

……

On the vast, dark battlefield, players from both races roared as they charged toward each other.

The two races were sworn enemies, and the allure of military merit and the promise of exchanging it for human blood food drove them to even greater madness.

This place is only in contact with the outside world when supplies are being transported; otherwise, it is basically in a closed state.

Therefore, the Dark Realm was completely unaware of the attack on the two races' forces.

Even the announcement of Brian's return to the throne of Frostfire had no effect here.

Because in the eyes of the leaders of the two races, no matter who the ruler of the Frost Prison Kingdom is, he will not cause trouble for the Dark Night Secret Realm.

This is one of the battlefields between the two races, not only in the Frost Prison Kingdom, but also in many other places.

In the event of a racial war, even a realm lord would not intervene casually.

This is one of the unwritten rules in the myriad worlds.

Unfortunately, the leaders of both races were unaware of the kind of being they were about to encounter.

Even if Su Mubai knew this rule, he wouldn't care about it.

Brian never even mentioned this unwritten rule to Su Mubai.

Because he knew very well that the fate of vampires and werewolves was sealed the moment they appeared on the death list.
