Inside Icevalley City.

On the streets, the Kader Knight is leading a team to kill the Snow Demon, and the vice-captain Bray works perfectly with him to successfully kill a Snow Demon alienated from a low-ranking knight.

"Bray, do you have any feelings, the number of snow demons in Ice Valley City seems to have decreased with the naked eye recently."

Kader Knight said.

Hearing this, Bray nodded: "Indeed, at the beginning, I felt that we could meet the snow demon by walking a few steps, and we didn't need to take the initiative to find it, but now, we still need to take the initiative to search before we can meet the snow demon, this is unreasonable, could it be that the snow demons in this city are all concentrated in the Blue Feather Castle?" ”

Kadell frowned slightly: "It's possible." ”

But the figure of the white wolf flashed in his heart.

In the past ten days, they have not met the white wolf again.

He felt that the decrease in the number of snow demons in this marginal city might also be related to the white wolf.

The two heavily armed knights, paired with the extremely pure Mithril Sword, may be no less efficient than their demon hunting team.

After ten days of cleaning, they have basically eliminated the snow demons in the fringe areas and saved many survivors.

The rescue effort went much smoother than Kader had imagined.

Because of the entire fringe city, the number of snow demons is far lower than he expected.

That's a good thing for the Cader Knights.

But for many wandering knights, it's a bad thing.

Many wandering knights have not killed even a single snow demon since they set out, on the one hand, their strength is too weak, and on the other hand, they basically haven't encountered any snow demons along the way.

I met some scattered three or five of them, and they were also robbed and killed by the strong people in the team, such as the deputy captain of Bray.

Frostheart, it won't be their turn at all.

"Captain, why don't we go inside?" Someone complained.

"If you want to die, you can go in by yourself, the danger in the depths of the city is far beyond your imagination, even if the big knight enters, it is possible to fall, who gave you the confidence to go deep?" Cadell lashed out at the wandering knight, who kept his mouth shut.

Kader sneered in his heart, if it weren't for the two great knights who helped them clear out a large part of the snow demons on the edge of the city, then this team of two hundred people, in the past ten days, would not be as simple as killing twenty people.

His primary goal now is to bring back as many survivors as possible, so he doesn't want to go out of his way into the city.

The chances of survivors deep in the city are slim, so there's no need to take the risk.

"Such a strong man appeared in the Kingdom of Eternal Night, and he had to report to the queen when he returned." Kadr Knight thought so.

The queen of the kingdom of eternal night is a rare female knight in this world, and she likes to recruit strong people to her command and make friends with heroes from all walks of life.

Kader sensed that the queen would be interested in the white wolf and the great knight beside him.

I hope the two of them don't die in this Icevalley City.

……

In the depths of the city, the demon shark in iron armor was like a war machine, killing several snow demons rushing forward.

Although the sword of the demon shark is not as good as Levi's Frost Sorrow, the content of Mithril in it is also one-tenth, far exceeding the swords of those demon hunters.

Therefore, the efficiency of the demon shark to hunt the snow demon is very high.

These days, in order to save his physical strength, Levi has stopped moving.

Although he had three months of food energy stored in his whale bag, because of the previous battle and consumption, ten days had passed, and now there was only one and a half months left.

If there is a big war, it will not last for a month and a half.

And the food on his body has long been gone, so after he is in the fifth order of the Hell Seal, he will not fight by himself, but use the demon shark to farm monsters, and he can only be the pendant of the demon shark and pick up the core of the undead in the back.

Levi ————

Hellseal: Fifth Order (2456/20000)

……

By now, Levi had killed more than four hundred snow demons.

According to the information he had received before, in ten days, he had reduced the number of snow demons in the city by about one-tenth.

This kind of efficiency is simply terrifying.

Truly, I am an army alone.

"It's so cool."

"Mowing the grass is unparalleled, cool to the extreme!"

It's just a little different from Levi's plan.

The fifth-order Hell Seal is not the limit.

Originally, he planned to kill some snow demons after the fifth order and go back.

Now I can only continue to experience the liver here.

Fortunately, there is a big knight like the Demon Shark, and the efficiency is not bad.

"When I get deeper into the city, if I can find some food to replenish, I can continue fighting."

"It's a good feeling to be a necromancer, even though I'm only a half-necromancer." Levi's heart was full of joy.

He plays games, and his favorite genre is the Stacked Armor Stream.

The second is to summon streams, play dark games, and like professions like necromancers.

Summon the stream, highlighting one word: cool.

"It's a pity, I still have three summoning slots, but I don't have the corpse of the Great Knight." Levi was a little sorry.

"In the future, if I kill the Duke of Montenegro, I will make him my living dead and let him do the dirtiest and most tiring work every day."

"And the Pale Shadow, don't even think about running away, sooner or later, I'll make him a living dead."

Levi wants to make his enemies cattle and horses for himself forever, so that they can experience the blessings of being social animals!

Levi's vacant summoning slot was for his enemies.

"Go ahead with the liver, no matter what, I'm going to take the Hell Seal liver to the limit! If you miss this village, you won't have this store. ”

Li Wei said in his heart, he finally came to the Eternal Night Kingdom, so naturally he couldn't waste this opportunity.

Five days later.

“298。”

“299。”

“300。”

Levi's face was pale, and he followed the demon shark with all his attention, watching the demon shark use his frost sorrow to kill in all directions.

After changing the Demon Shark with its own weapon, the Demon Shark's efficiency was much higher, at least three times higher.

Beside the big demon shark in front of him, there are three freshly baked "living dead".

The three living dead are very weak, and they just follow the demon shark to play soy sauce.

These three living dead are all from some wandering knights who have come to trouble Levi without knowing whether they are alive or dead during this time.

Levi summoned them purely for the sake of rapid proficiency in the Liver Hell Seal.

Now he has a lot of undead cores on him, but if there is only one demon shark, the amount consumed is far less than the amount that Levi obtained.

This also means that the speed of Hellmark proficiency acquisition is too slow, after all, the Demon Shark is the only one earning proficiency for Levi.

As a result, Levi could only make the corpses of the strongest and only mid-level knights into the living dead, and use them to increase the speed of brushing proficiency.

The effect is also immediate.

Don't look at these guys as weak, but they provide a lot of proficiency.

So the speed of Levi's liver suddenly increased several times.

Along with the appearance of the third hundredth snow demon killed by the demon shark.

Levi's Hellmark has been upgraded again.

Levi ————

Hell's Seal: Tier 6 (1/40000)

……

"Isn't it the limit? It's all sixth-order......"

"It's unbelievable that my current realm of the Hell Seal even surpasses the ancestors of the Constantine family......"

"To be honest, the difficulty of the Fa Seal cultivation is much smaller than that of the Breathing Method, but it is limited by too few spell casting materials, otherwise, the Fa Seal cultivation is really not difficult."

Levi's heart was calm, since the sixth order was not the limit.

Then he will continue to be liverless, and he will not believe it.

Can this seal go on forever?

That's okay, if this magic seal can reach the level of 10,000.

Summoning 10,000 living dead, the wizard will shake his head when he sees it, right?

So he felt that there was still an upper limit to this seal.

"Maybe the seventh order is the upper limit."

"Let's liver for a while, anyway, the time I reserved for myself is a month, and now it's only half a month."

Li Wei said in his heart.

The Hell Seal Liver reached the sixth order, and he had six summoning slots.

You can now add a new cannon fodder.

So along the way, he would pay special attention to the corpses of the living dead who could barely make up for use.

Before he knew it, Levi had gone deep into the inner city.

"As long as you don't enter that castle for a while, it should still be safe."

Levi felt the danger coming from the spider's senses, and muttered to himself.

In the end, Levi did not find the knight-level corpse either.

I can only temporarily use the corpses of ordinary people to make up the numbers.

Anyway, I don't expect them to fight, it's just to brush up on their own experience.

And, to be honest, even if he gave Levi six living dead at the level of a great knight, he felt that he might not be able to control it.

Driving the living dead is not completely depleting for the master, but will consume spiritual power.

Mental power is ethereal, but it does exist.

A wizard is a cultivator of spiritual power, and Levi is not a wizard now.

But with his great knight-level realm, his spiritual power must be higher than that of ordinary people.

He roughly estimated it, with his current mental strength.

At most, he can control the living dead at the level of five great knights.

If you want to completely control the six great knights of the living dead, you should at least have the realm of top knights.

Time flickered, and another ten days passed.

It's been twenty-five days since Levi arrived in Icevalley.

The demon hunter team had already returned with the people of the kingdom who had been rescued this time, and because Levi was constantly clearing monsters in front, the rescue operation of the Kader Knight was going well.

The only thing that is not happy is probably those wandering knights.

They were going to get some Frost Hearts in exchange for bounties.

As a result, many people didn't even kill a snow demon in the end.

Although they pay lip service to their abilities, no one dares to go deep into the city.

After seeing a few wandering knights who did not believe in evil being dismembered in a matter of seconds by dozens of snow demons that suddenly appeared, they were completely honest.

And Levi had already arrived at the periphery of Blue Feather Castle.

He looked at his proficiency panel.

Levi ————

Hellseal: Tier 6 (30000/40000)

……

"Damn, it's almost there, but in the huge Ice Valley City, except for the scattered snow demons scattered in various urban areas, you can't see it at all."

Up to now, the number of snow demons that have died under Levi's hands has reached thousands.

According to the information obtained by Levi, there are only three or four thousand snow demons in this Ice Valley City at most.

"There are still 100 left, and it's too slow to find one in other places, why don't you go to the castle for an interview?" Levi looked at the majestic castle.

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

The buildings inside are densely packed, and it is basically a small city within a city.

The black castle sleeps like a dormant beast in front of it.

A large number of snow demon roars can be heard inside.

Levi took out all the cores of the undead in the bodies of the living dead as cannon fodder.

"We don't need them anymore, and it might be bad to keep them."

Levi took the Demon Shark, who was light in stature, and came to the walls of the Blue Feather Castle.

Then he gently touched his palm against the wall.

Use your advanced vibrational perception to feel the movement inside the castle.

The range of his advanced vibrational perception now is thirty meters in radius.

So he wanted to see how many snow demons there were within a radius of thirty meters with him as the center, so as to estimate the density of the snow demons, and then decide whether to go in or not.

"Five."

"It's not high, but it's not low."

"You can give it a try, or send a few cannon fodder first, and go to the castle to bring some out."

"I'm afraid that if I accidentally lure out all the snow demons in the castle, then I will have to run away."

Levi made a choice in his mind.

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

He re-injected the Undead Core into the body of a mid-level knight-level living dead.

Let the living dead creep in through the castle's broken gates.

It didn't take long for Levi to feel as if a snow demon was attacking the living dead, and he quickly manipulated the living dead to come out.

Then Levi saw a bunch of snow demons chasing the living dead, and when he reached the door, he stopped, and after wandering back for a while, he went back again.

"What's the situation?"

Levi wondered why these snow demons didn't leave the castle.

He didn't believe in evil, so he tried again with other living dead.

Even let the demon shark try it, and found that the living dead were chased to the door and never came out.

Levi pondered for a moment, then climbed to the city wall through the grappling hook, sneaked out of his sneaky head, and looked inside.

I saw that the castle was full of snow demons, and the deeper the castle, the denser the snow demons became.

No wonder you can't find the snow demons outside, they are all concentrated here.

Under the tallest building of the castle, possibly the Duke's Palace, there were hundreds of snow demons, all of them wearing blue feather armor.

"This seems to be the alienated snow demon of the army below Duke Blue Feather."

Levi also found that there were more than a dozen knight-level snow demons with an aura and costumes that were obviously different from ordinary snow demons roaming.

"Twelve, the weakest are all mid-level knights, and the strongest is the snow demons of the peak knight level."

"No, there's another one." Levi suddenly saw a large snow demon who was not inferior in size to the demon shark, he was already rotting and only his bones remained, and he was still inspecting the castle dedicatedly.

"Thirteen-headed knight-level snow demons, and even a big knight-level, no wonder no one dares to come here."

Levi knew that an ordinary Great Knight, unless he had such a high-purity Mithril Sword and extraordinary endurance as himself, it would be difficult for him to be an opponent of the Great Knight-level Snow Demon.

Because the snow demon is not only not inferior to the big knight in terms of physical fitness, but also has no weaknesses, is immortal and indestructible, is not afraid of death, and has mastered the combat skills in front of the big knight, which is terrifying.

That is, you can deal with such a monster by yourself.

"If it's just this big knight, it shouldn't give me the sense of danger that I feel like spider sense, could it be that there are other dangers in this castle?" Levi observed the situation and hesitated to kill him.

He currently had a hundred Undead Cores left to make the Hell Seal Seventh Order, and in addition, he also needed to stock up on a few hundred Undead Cores for his future use.

Now it seems that most of the remaining snow demons in this city are in this castle, and if you don't go in, it would be too wasteful to go to other places to find those scattered ones.

"Brush up enough undead cores and quit, never fall in love with war."

Levi finally made a decision.

"I have extraordinary defense, extraordinary endurance, top strength, top speed, advanced perception, and artifacts like pure Mithril's Frost Giant Armor and Frost Sorrow, not to mention the four major magic seals, although there is a certain danger, but self-protection should be no problem, you don't need to go too deep." Levi analyzed it.

Prepare the spell casting materials, and then take the demon shark and touch the castle.

He let the Demon Shark stand in front of him, and once there was an enemy that he was incapable of, he let the Demon Shark sacrifice himself and let him escape.

As soon as he entered, a snow demon noticed Levi.

At least dozens of snow demons are coming towards Levi.

Levi took the demon shark and came to a city wall.

That way he doesn't have to worry about having enemies behind him.

"Come on."

Levi was ready.

The Demon Shark turned into a killing machine, blocking in front of Levi, using the Frost Grief to kill all directions, and occasionally some fish that slipped through the net passed through the Demon Shark's defensive net, and were also crushed by Levi's direct black qi hand, and directly took out the core of the undead.

……

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

As soon as the battery ran out, he took the demon shark out of the castle.

Replace the Demon Shark with a new Undead Core.

None of those snow demons left the castle.

This made Levi even more puzzling, he couldn't understand why these snow demons were like this.

It stands to reason that snow goblins are territorial-minded, roaming around in search of any flesh and blood, like locusts.

But the snow demon in this blue feather castle seems to be inseparable from this castle.

"Could it be that there is some treasure in this castle?" Levi pondered.

"But I'm not interested, I just want to leave this hellish place with the seal of hell and the core of the undead."

Levi resisted his curiosity and greed, which would only put himself in danger.

It's better to fill the liver of the seal of hell steadily.

In this way, relying on this method, Levi kept going in and out of the castle, using the demon shark and consuming with these snow demons.

In one day's effort, the demon shark killed hundreds of snow demons, and the efficiency was several times that of the outside.

On the third day, Levi's Hell Seal finally broke through again.
