On the lake, the body of the knight was dragged ashore by Levi.

Levi stripped off his armor and everything else.

Most of the things on his body had been burned by the Seal of Flame.

"Damn, it's a good thing this person didn't bring any breathing method inheritance diagram, otherwise it would have been burned and I would have been heartbroken." Levi suddenly thought.

But if it happened again, Levi would still do it. Breathing method is precious, but life is more precious.

In the end, he found hundreds of gold coins, a shark-tooth broadsword, and a half-burned portrait on the great knight. When he saw the half face in the portrait, Levi suddenly remembered where he had seen it.

"I got the 'Exorcism Notes' from the middle-aged nobleman I killed before. That person is connected to the Duke of Montenegro. The Duke of Montenegro is asking this great knight to find that person."

"Could it be that the Duke of Montenegro is also looking for clues about the wizard? Does he also know the secrets of the four extraordinary families?" Levi pondered in his heart.

"Haha, anyway, the inheritance belongs to me now. Now that I have intercepted it, the old dog Black Mountain will be so pissed off." The most infuriating thing is that the Duke of Black Mountain has no idea who intercepted it.

In the end, Levi got nothing from this great knight except gold coins and the shark-tooth broadsword.

"It's a rubbish sword. The only thing about it is the materials. I'll add some mithril and recast it when I get back. I'll let the big guy use it."

The big guy is dead, and Levi doesn't even know his name.

But it doesn’t matter what his previous name was. From now on, Levi will call him “Demon Shark”.

“What comes next is what I’m really looking forward to.”

"Seal of Hell!"

Levi took out the core of the undead.

The Mark of Hell spell requires a ready corpse to cast.

In other words, it is similar to a "corpse chaser".

"A corpse of a great knight, after being resurrected through the Seal of Hell, should at least have the combat power of a peak knight." Levi thought to himself.

Casting the Mark of Hell requires some other materials.

After Levi hid the body of the great knight, he returned to Icewind City.

…

Silver Mountain Castle.

The handsome Earl Yinshan was wearing brand new armor and looking at himself in the mirror.

"It's perfect." Earl Silver Mountain said to himself.

I don’t know whether to praise the armor or to praise myself.

Soon, his men came in.

"My Lord Earl, I have sent an invitation letter to Master Terra. We are scheduled to meet at the Shining Tavern in three days."

"Okay, you can go down." Earl Yinshan looked at the mirror in deep thought, remembering the Frost Heart that appeared at the auction.

He is not only a well-known noble in this kingdom, but also a great knight.

Naturally, he sees and knows more than ordinary people.

The world has changed since the turn of the millennium.

The church's change in attitude from being unwilling to acknowledge the existence of evil spirits before the millennium to beginning to acknowledge them is an intriguing change.

All over the country, the number of attacks by evil spirits has been increasing year by year. Of course, the number of people killed by attacks by evil spirits is still not a fraction of the number of natural and man-made disasters such as war and famine.

However, this is not a good sign.

If the attack of evil spirits is still a low-probability event.

The frequent invasions of snow monsters in the Kingdom of Eternal Night are almost a sign of the coming of the Dark Ages.

Although snow monsters are not as scary as evil spirits and are physical creatures that can be killed by ordinary people, their numbers are increasing day by day.

Judging from the information currently available to Earl Yinshan, the snow monster seems to be a mutation of some residents of the Kingdom of Eternal Night.

No one knew when this disaster began, and no one paid much attention to it at first. Until the arrival of winter, the snow monsters had become a disaster.

The entire Kingdom of Eternal Night has been troubled by these incomprehensible undead creatures. The Ice Queen has repeatedly asked the neighboring Emerald King and the Emperor of the Tuva Empire for help.

Unfortunately, the Emerald Kingdom was old and timid. He sat on the decaying dragon bone throne and rejected the request of the Ice Queen. He wanted to focus his limited energy on the intrigues with the great nobles below.

The neighboring Tuva Empire has been in a state of civil war since the rebel uprising at the end of last year. The Imperial Fist is missing, and although the rebels have temporarily occupied the Holy City, the fanatical supporters of the Imperial Fist are still fighting tenaciously. The two waves of troops have expanded the war from the Holy City to the entire country, and the battle is fierce.

So, no one came to the aid of the Snow Queen.

However, Earl Silver Mountain, who had witnessed the horror of the Snow Monster with his own eyes, knew that if the three countries close to the Far North could not unite now and eliminate the Snow Monster in its infancy as soon as possible, then this disaster would spread from the Kingdom of Eternal Night to the Emerald Kingdom, the Tuva Empire, and might even spread to the entire Seven Kingdoms in the future!

The kingdom territory closest to the Far North is the Black Mountain Province. The Ice Wind Territory in the Black Mountain Province will be the first to be threatened.

"Something must be done. This corrupt kingdom is too big to be eliminated, like a millipede with each leg having its own independent mind."

Regardless of whether the kingdom takes action or not, as a great noble in the north, he must consider the millions of subjects and the inheritance of the Silver Mountain family. He knows that the Duke of Black Mountain thinks the same way.

Now, Earl Silver Mountain has hoarded a lot of mithril.

He needed a true craftsman, such as Master Terra, to equip him with an army fully equipped with the finest mithril armor and mithril weapons.

"Who would have thought that a tiny bit of mithril would be the key to fighting against undead creatures like the snow demon?"

Earl Yinshan muttered to himself, waiting for the meeting with the master in three days.

In Icewind City, Levi quickly collected other materials for casting the Seal of Hell from the Emerald Chamber of Commerce and the Shining Tavern.

After confirming that no one was following him, he quickly returned to the Tianchi Island.

Harris followed Levi, circling in the sky and keeping watch for him.

On the small island, the body of the demon shark was already cold.

But the temperature is still relatively cool now, so it won’t rot so quickly.

Especially since the Demon Shark itself is a great knight with a very powerful body.

"Preservatives, mercury..."

Levi counted the materials one by one.

Before casting the Seal of Hell, the body must first be embalmed, then injected with mercury and wrapped in a manner similar to mummification.

After half a day, it was almost done.

Levi took out the core of the undead.

The blue mist was dispersing, which was very beautiful.

This blue flame is like the soul fire in the eye sockets of undead skeletons in some games.

Levi had already memorized the hand gestures of the Seal of Hell.

Soon, he finished making the seal.

At the same time, he was still mumbling something. He used the syllables that the Constantine family used to communicate with Hell. Translated into the language of this world, it roughly meant:

"The lonely soul of hell, I grant you a new life."

boom!

A force came from the darkness.

The core of the undead slowly rotated, emitting a dazzling blue light, and then drilled into the demon shark's head which had been disfigured beyond recognition due to burns.

Levi held the spell materials for the Guardian Seal and the Flame Seal in his hands, ready to deal with any unexpected situations at any time.

After about a few breaths, a faint blue flame suddenly emerged from the eye sockets of the magic shark's head. Waves of frosty power covered the magic shark's face, emitting a hint of coldness.

After a moment, the blue flame began to shrink, and finally became the size of a green bean, shining like a blue pupil.

Not long after, the dead and stiff body of the magic shark began to tremble, and finally the corpse of the magic shark stood up straight and strangely, like a zombie in a movie.

Levi was startled, with the seal of flame flow on his right hand and the seal of fire on his left hand, and black air also covered his upper body.

However, the demon shark's body did not move after it stood up.

Levi continued to make hand gestures according to the Seal of Hell. At the same time, the body of the Demon Shark began to walk, from being stiff at the beginning to becoming more and more smooth later, until it was almost indistinguishable from a real person.

"This is much better than driving corpses." Levi exclaimed in his heart.

Then he ordered the magic shark to attack a tree.

The Demon Shark charged forward like a locomotive, and even picked up the serrated broadsword on the ground!

Boom!

Black gas wrapped around the demon shark's arm and finally appeared on the serrated broadsword.

Click.

The tree as thick as a bucket was easily chopped down by the magic shark.

"Good boy, you can even use black energy."

“That’s quite impressive.”

Levi was shocked.

Try to make the Demon Shark perform more combat moves.

After playing like this for more than ten minutes.

Levi has almost completely learned how to control the magic shark.

He discovered that the Demon Shark's fighting power was indeed much weaker than when it was alive.

But he is still much stronger than the peak knight, and can barely be considered a great knight.

Levi used himself as an experiment and found that the Demon Shark was actually fighting him more and more. If he didn't use those killer cards, the Demon Shark would still be very strong.

"Very good, my fighting power has increased again, although it is an external force."

Levi was very excited. With the help of the Demon Shark, his strength was improved to a higher level. Although the Demon Shark's strength was only that of a half-great knight, he was definitely a loyal puppet.

For Levi, this is much more useful than a big knight's subordinate.

After all, the Great Knight's men might betray him.

But the demon shark won’t!

After finishing all this, he looked at his proficiency panel.

Sure enough, a new skill appeared.

Levi——

Seal of Hell: Level 1 (5/1000)

…

"Hey, the third seal finally appeared on the proficiency panel. No, I just cast the spell once, how come the skill proficiency increased so much?"

Judging from Levi's research on the Seal of Flame and the Seal of Protection, each time a spell is cast, the proficiency increases by 1 point, which is unchangeable. This is completely different from practicing breathing techniques.

Until Levi saw the lines of prompts below the proficiency panel:

[Hell Seal Mastery +1]

[Hell Seal Mastery +1]

[Hell Seal Mastery +1]

…

Suddenly, Levi understood something.

He only needs to use hand seals to control the "Magic Shark" to fight for a long enough time.

The proficiency of Hell Seal will increase by 1 point.

"Then this skill will be developed quickly."

"However, the energy stored in each Undead Core is limited. Every time the Demon Shark fights, it needs to consume a lot of energy from the Undead Core, so there is still a limit."

Levi asked the Demon Shark to stop, and then he made a finishing hand seal.

The core of the undead in the demon shark's eye socket appeared in Levi's hand again.

Levi took a look and found that one twentieth of the energy of the Undead Core had been used.

"That is to say, if the energy of a Undead Core is used up, it can only increase the proficiency of the Seal of Hell by 100. It takes 10 such Undead Cores to advance to the second level? Where the hell can I find so many Undead Cores? Do I have to go to the Far North to kill the Snow Monster myself?"

Levi no longer dared to play casually.

"Perhaps the quality of this Undead Core is too low."

According to the notes, the stronger the undead's strength, the higher the quality of the undead core that is born.

Levi injected the core of the undead into the body of the demon shark again.

This time he did not let the Demon Shark use black energy to fight, but just let him follow him.

Levi's research found that if there is no fighting, it is just an ordinary drive.

The energy of the Undead Core consumed by the Demon Shark was very little.

At this rate of consumption, only about 1% of energy is consumed per day.

"I understand. The Undead Core is a battery. Walking is standby mode, and fighting is a game that consumes energy."

Levi gradually understood the principle of the Undead Core.

This made him feel relieved. He was worried that the Demon Shark would have to expend a lot of energy walking, and then the Seal of Hell would be useless.

He couldn't just make a big coffin, put the demon shark in it, and carry it on his back every day.

Levi used the materials he had prepared in advance to put makeup on the Demon Shark and cover up the corpse stench on the Demon Shark. Then he let the Demon Shark put on his own armor, put on an iron helmet, carry a serrated giant sword, and follow him, returning to Icewind City under the cover of night.

The next day, Levi found a place to recast the highly recognizable serrated broadsword into a normal giant sword.

He also personally tailored a set of fully armed armor for the Demon Shark.

The entire body of the Demon Shark is hidden by armor, and with the airtight iron helmet, it is not easy for others to notice his abnormality.

Although there is still a slight odor, many nobles and knights in this world do not pay much attention to hygiene, so it is normal to have a bad smell.
