Seventh-Order Seal, Hell Apostle!

) in Ice Valley City.

On the street, Kader Knight was leading his team to kill Snow Wraith. His vice-captain, Bray, worked perfectly with him and successfully killed a Snow Wraith that had been mutated from Low-Rank Knight.

"Bray, have you noticed that the number of Snow Wraith in Ice Valley City seems to have decreased visibly lately?"

"Kader Knight said."

Upon hearing this, Bray nodded. "Indeed, at first it seemed like we could encounter Snow Wraith just by walking a few steps, without needing to actively search for them. But now, we actually need to actively search to encounter Snow Wraith, which doesn't make sense. Could it be that Snow Wraith in this city have gathered at Duke Blue Feather Castle?"

Kadeer frowned slightly. "That's possible."

However, the image of the White Wolf flashed through his mind.

For the next ten days, they did not encounter the White Wolf again.

He felt that the decrease in the number of Snow Wraith in this outlying urban area might also be related to the White Wolf.

Two fully armed Great Knight, equipped with Mithril of extremely high purity, might be just as efficient as their demon-hunting team.

After ten days of cleanup, they have essentially eradicated the Snow Wraith from the outskirts and rescued many survivors.

The rescue operation went much more smoothly than Kadeer had imagined.

Because the number of Snow Wraith in the entire outlying city was far lower than he had expected.

This is good news for Kader Knight.

But for many Wandering Knight, this is a bad thing.

Many Wandering Knight have not killed a single Snow Wraith since they set out, partly because they are too weak, and partly because they have hardly encountered any Snow Wraith along the way.

They encountered a few scattered individuals, but they were quickly killed by the stronger members of the team, such as Vice Captain Bray.

The Frost Heart is not for them at all.

"Captain, why don't we go further in?" someone complained.

"If you want to die, you can go in by yourself. The dangers deep inside the city are far beyond your imagination. Even Great Knight could perish if he went in. Who gave you the confidence to go in?" Kadeer rebuked the Wandering Knight, who then shut his mouth.

Kadeer sneered inwardly. If it weren't for those two Great Knight helping them clear out a large portion of the Snow Wraith on the edge of the city, this team of two hundred men would have suffered far more than just twenty deaths in the past ten days.

His primary goal now is to bring back as many survivors as possible, so he doesn't want to cause any unnecessary trouble by venturing deeper into the city.

The chances of finding survivors deep within the city are slim; there's no need to risk it.

"Such a powerful figure has appeared in the Eternal Night Kingdom. I must report this to the Queen upon my return," Kader Knight thought to himself.

The Queen of the Eternal Night Kingdom is a female Great Knight rarely seen in the world. She likes to recruit strong people to her cause and befriend heroes from all walks of life.

Kadeer sensed that the Queen would be very interested in the White Wolf and the Great Knight beside him.

I hope they don't die in this Ice Valley City.

Deep within the city, the armored Demon Shark, like a war machine, charged towards several Snow Wraith rushing towards it.

Although the Demon Shark's sword is not as good as Levi's Frostmourne, it still contains one-tenth the amount of Mithril, far exceeding the swords of those demon hunters.

Therefore, the efficiency of the Demon Shark in hunting Snow Wraith is extremely high.

In order to conserve his energy, Levi has not done anything these past few days.

Although he had stored three months' worth of food and energy in his Whale Sac, due to the previous battles and the resulting consumption, ten days have passed, and now only one and a half months' worth remains.

If there were a major battle, they wouldn't be able to hold out for even a month and a half.

He had long since run out of food, so after reaching Fifth Order of the Hell Seal, he stopped fighting on his own and instead used the Demon Shark to farm Demon Shark, acting as its accessory and collecting Undead Core from behind.

[Hell Seal Proficiency +1][Hell Seal Proficiency +1]...

Levi ————

Hell Seal: Fifth Order (2456/20000)

By now, Levi has killed more than four hundred Snow Wraith.

According to the intelligence he had previously obtained, he reduced the number of Snow Wraith in the city by about one-tenth in ten days.

This efficiency is simply terrifying.

I am truly an army all by myself.

"That was awesome."

"Unrivaled mowing of the grass, the ultimate thrill!"

However, it differs from Levi's plan in that...

The Fifth Order Hell Seal is not the limit.

He originally planned to kill some more Snow Wraith after reaching the Fifth Order and then go back.

Now all I can do is continue grinding for experience here.

Fortunately, we have Great Knight like the Demon Shark, so the efficiency is not bad.

"Once we get deeper into the city, if I can find some food to replenish my supplies, I can continue fighting."

"It feels great to be a necromancer, even though I'm just a half-baked one," Levi thought to himself, feeling quite pleased with himself.

His favorite playstyle in games is the Armor Stacking Style.

Secondly, there's the summoner build; those who play Diablo-like games especially enjoy classes like necromancers.

Summoning style, the key word is: awesome.

"What a pity, I still have three summoning slots, but I don't have the Great Knight's corpse." Levi said with some regret.

"After I kill the Black Mountain Duke, I will turn him into my Living Dead and make him do the dirtiest and most tiring work every day."

"And the Pale Shadow won't escape either. Sooner or later, I'll turn him into Living Dead too."

Levi wants to make his enemies serve him like slaves for eternity, letting them experience the "blessings" of being corporate slaves! The vacant summoning slot in Levi is reserved for his enemies.

"Keep grinding! No matter what, I'm going to grind the Hell Seal to the limit! If I miss this opportunity, I won't get another one."

Levi thought to himself, "I've finally come all the way to the Eternal Night Kingdom, so I can't waste this opportunity."

Five days later.

298.

"299."

300.

Levi's expression remained calm as he followed closely behind Demon Shark, watching Demon Shark Frostmourne.

After equipping the Demon Shark with its own weapon, the Demon Shark's efficiency increased significantly, by at least three times.

Beside the giant Demon Shark in front, there are three newly formed "Living Dead".

These three Living Dead are very weak; they're just following behind Demon Shark and doing nothing else.

These three Living Dead were all Wandering Knight had been recklessly causing trouble for Levi during this period.

Levi summoned them purely to quickly increase his proficiency with the Hell Seal.

He now has a large number of Undead Core, but if it's just Demon Shark alone, the amount he consumes is far less than the amount Levi has acquired.

This also means that the speed at which Hell Seal proficiency is gained is too slow, since only Demon Shark is earning proficiency for Levi.

Therefore, Levi could only turn the corpses of these few, the strongest of whom were only Mid-Rank Knight, into Living Dead, using them to increase the speed of grinding proficiency.

The effect is immediate.

Don't let their weakness fool you; they actually provide a significant amount of proficiency points.

Therefore, Levi's liver speed increased several times over.

The three hundredth Snow Wraith, killed by the Demon Shark, appeared.

Levi's Hell Seal has been upgraded once again.

Levi ————

Hell Seal: Sixth Order (1/40000)

"This isn't even the limit? It's already at the Sixth Order..."

"Unbelievable, my current level of Hell Seal even surpasses that of the ancestors of the Constantine Family..."

"To be honest, the difficulty of practicing the Rune Seal is much less than that of the Breathing Technique. It's just that the Casting Material are too few. Otherwise, practicing the Rune Seal is really not difficult."

Levi remained calm, since the Sixth Order was not the limit.

He'll keep working on it, he just won't believe it.

Can I keep grinding this Rune Seal indefinitely?

That would be incredible, if this Rune Seal could be leveled up to 10,000.

Summoning ten thousand Living Dead would make even a wizard shake his head in disbelief, right? So he felt that this Rune Seal still had an upper limit.

"Perhaps the Seventh Rank is the upper limit."

"Let me work on it for a while longer. I gave myself a month, and only half a month has passed so far."

Levi thought to himself.

He upgraded the Hell Seal to Sixth Order, gaining six summoning slots.

Now we can add another cannon fodder.

Therefore, he paid special attention to whether there were any Living Dead corpses along the way that could be used even if they were barely usable.

Unbeknownst to him, Levi had already ventured deep into the Inner City.

"As long as we don't go into that castle for the time being, we should still be safe."

Levi felt the danger emanating from his Spider Sense and muttered to himself.

Ultimately, Levi did not find the body of Knight.

We had no choice but to temporarily use ordinary human corpses to make up the numbers.

Anyway, I don't expect them to fight; they're just there to give me experience points.

Moreover, to be honest, even if Levi were given six Living Dead at the level of Great Knight, he felt he might not be able to control them.

Controlling the Living Dead is not entirely effortless for the master; it consumes mental energy.

Spiritual power is ethereal and intangible, but it does exist.

Wizards cultivate spiritual power, but Levi is no longer a wizard.

However, given his Great Knight level, his mental strength is definitely above that of ordinary people.

He made a rough estimate based on his current mental strength.

At most, he can only command five Living Dead at the level of Great Knight.

To fully control the six-headed Living Dead Great Knight, one would need to be at least at the level of Peak Great Knight.

Time flies, and another ten days have passed.

Levi has been in Ice Valley City for twenty-five days.

The demon hunter team had already led the rescued citizens of the kingdom back home, and because Levi was constantly clearing monsters ahead, the rescue operation of the Kader Knight went very smoothly.

The only ones who are unhappy are probably those Wandering Knight.

They originally came to collect some Frost Heart in exchange for bounties.

As a result, many people ended up failing to kill even a single Snow Wraith.

Although they talked a big game, none of them dared to actually venture deep into the city.

After witnessing several skeptical Wandering Knight being torn apart in seconds by dozens of Snow Wraith that suddenly appeared, they became completely obedient.

Levi had already arrived at the outskirts of Duke Blue Feather Castle.

He looked at his Proficiency Panel.

Levi ————

Hell Seal: Sixth Order (30000/40000)

"Damn it, we were so close! But in the huge Ice Valley City, apart from a few scattered Snow Wraith in various districts, we couldn't find any at all."

To date, over a thousand Snow Wraith have died at Levi's hands.

According to the intelligence Levi obtained, there are at most three or four thousand Snow Wraith in this Ice Valley City.

"We're still short 100. It's too slow to look for them one by one in other places. How about we try our luck inside the castle?" Levi gazed at the majestic ancient castle.

As the duke's castle, Blue Feather Castle is very grand.

The buildings inside are densely packed, making it essentially a small Middle City District.

The black castle, like a slumbering beast, lies dormant in the distance.

Inside, you can hear the roars of numerous Snow Wraith.

Levi extracted all the Undead Core from the bodies of those cannon Living Dead.

"We don't need them anymore; keeping them might actually cause problems."

With the Demon Shark by his side, Levi moved nimbly to the edge of the Blue Feather Castle's walls.

Then he gently touched the wall with his palm.

Using its Advanced Vibration Perception, it sensed the movements within the ancient castle.

His current Advanced Vibration Perception range is a radius of thirty meters.

So he wanted to see how many Snow Wraith were within a 30-meter radius of himself, in order to estimate the Snow Wraith density and decide whether or not to go in.

"5."

"Not high, but not low either."

"We can give it a try, or we can send a few cannon fodder to lure some out of the castle."

"I'm afraid I might accidentally lure all the Snow Wraith out of the castle, then I'll have no choice but to run away."

Levi was making a decision.

In the end, I decided to give it a try.

He reinserted the Undead Core into the body of a Mid-Rank Knight- level Living Dead.

The Living Dead slipped through the castle's broken gate.

Not long after, Levi sensed that a Snow Wraith was attacking the Living Dead, so he quickly controlled the Living Dead to slip away.

Then Levi saw a group of Snow Wraith chasing the Living Dead. When they reached the door, they stopped, lingered for a while, and then went back.

"What's going on?"

Levi was puzzled as to why these Snow Wraith didn't leave the castle.

He refused to believe it and tried again with other Living Dead.

Even the Demon Shark tried it out and found that the Living Dead would only chase them to the door and then stop coming out.

After pondering for a moment, Levi used a grappling hook to climb onto the city wall, cautiously peeking his head inside.

Inside the castle, Snow Wraith were everywhere, and the deeper one went into the castle, the more densely Snow Wraith were.

No wonder we can't find any Snow Wraith outside; they've all gathered here.

Beneath the tallest building in the castle, possibly the Duke's mansion, hundreds of Snow Wraith gathered, all clad in pale blue feathered armor.

"This appears to be a mutated Snow Wraith from the army under Duke Blue Feather."

Levi also discovered that there were more than a dozen Knight- level Snow Wraith whose aura and clothing were clearly different from ordinary Snow Wraith, and they were wandering around.

"The twelve Snow Wraith are all at the level of Mid-Rank Knight, and the strongest are at the level of Peak Knight."

"No, there's another one." Levi suddenly saw a huge Snow Wraith whose size was no less than that of Demon Shark. His body had rotted away and only bones remained, but he was still diligently patrolling the castle.

"Thirteen Snow Wraith at the Knight level, and even one at the Great Knight level, no wonder no one dares to come here."

Levi knew that ordinary Great Knight, unless they possessed a high-purity Mithril like his and Extraordinary Endurance, would find it difficult to be a match for Great Knight- level Snow Wraith.

Because the Snow Wraith not only possesses physical attributes comparable to the Great Knight, but also has no weaknesses, Undying and Indestructible, fearless of death, and has mastered the combat techniques previously used by the Great Knight, making her exceptionally terrifying.

Only I can deal with such a monster.

"If it's just this Great Knight, he shouldn't be giving me that Spider Sense danger. Could there be other dangers inside this castle?" Levi observed the situation, hesitating whether to charge in.

He is currently one hundred more Undead Core needed to upgrade the Hell Seal to Seventh Rank. In addition, he needs to stockpile several hundred more Undead Core for his future use.

It seems that most of the remaining Snow Wraith in the city are inside this castle. It would be a waste of time to search for the scattered ones elsewhere if we didn't go in.

"Once you've collected enough Undead Core, quit and don't linger in battle."

Levi finally made a decision.

"I possess Extraordinary Defense, Extraordinary Endurance, top-tier strength, top-tier speed, Advanced Perception, and divine artifacts like the Frost Giant Armor and Frostmourne made of pure Mithril. Not to mention the Four Great Seals cards. Although there is some danger, I should be able to protect myself without any problem. I don't need to go too deep," Levi analyzed.

After preparing the Casting Material, they took the Demon Shark and sneaked into the castle.

He had the Demon Shark stand in front of him as a shield, and if there was an enemy he couldn't defeat, he would have the Demon Shark sacrifice itself so that he could escape.

As soon as he entered, a Snow Wraith noticed Levi.

At least dozens of Snow Wraith charged toward Levi.

Levi, accompanied by the Demon Shark, arrived at the foot of a city wall.

This way, he wouldn't have to worry about enemies behind him.

"Bring it on."

Levi is ready.

The Demon Shark transformed into a killing machine, standing in front of Levi and unleashing Frostmourne to slaughter everyone in its path. Occasionally, a few stragglers would slip through the Demon Shark's defenses, but Levi would crush them with his Black Qi hand and extract their Undead Core.

[Hell Seal Proficiency +1][Hell Seal Proficiency +1]...

While fighting, Levi also estimated the remaining battery power of the Demon Shark based on his proficiency.

Once the battery was almost depleted, he slipped out of the castle with the Demon Shark.

Equip the Demon Shark with a new Undead Core.

None of those Snow Wraith left the castle.

This puzzled Levi even more; he couldn't understand why these Snow Wraith would act this way.

Logically speaking, Snow Wraith have no sense of territory; they roam freely, searching for any living creature, much like locusts.

But the Snow Wraith inside Duke Blue Feather Castle seems to never leave the castle.

"Could there be some kind of treasure inside this castle?" Levi wondered.

"But I'm not interested. I just want to max out the Hell Seal, get the Undead Core, and leave this hellhole."

Levi resisted his curiosity and Greed, knowing that doing so would only plunge him into danger.

It's best to just focus on maxing out the Hell Seal.

In this way, relying on this method, Levi kept going in and out of the castle, using the Demon Shark to wear down these Snow Wraith.

In just one day, the Demon Shark killed over a hundred Snow Wraith, several times more efficiently than those outside.

On the third day, Levi's Hell Seal was finally broken through once again.
