Inside the shelter, Levi held the Core of the Undead in his hand and chanted a spell.

With the second-level Seal of Hell, Levi can control two living dead.

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

The core of the undead slowly merged into Artos's skull.

That mysterious power filled Artos' body.

Blue will-o'-the-wisp flames burned in his empty eye sockets.

That was not a will-o'-the-wisp, it was just an icy-blue frosty air.

It may be because the snow demon is an undead with icy attributes, so the undead cores that are born have the same effect.

"Shark, come meet your friend, the Mountain."

Levi blurted out as he looked at Atos's body, which was as strong as a demon shark.

If there are four of them in the future, they will be the alien version of the "Four Heavenly Kings".

"Brother Mo, come and have a fight. Let me see."

Levi let the two brothers fight in hand-to-hand combat at the same time. The two muscular monsters collided with their fists, and black air was lingering.

Both of them are powerful knights with similar strengths.

They are somewhat inferior to the Seven Knights of Yinshan, and certainly cannot compare to the Duke of Black Mountain, the veteran knight.

However, with the two brothers of the Mo family, plus his own strength and trump cards, it is still uncertain who will win against the Duke of Black Mountain.

"Of course not now. I have to wait until I have the strength of a great knight before I can consider revenge on the Duke of Black Mountain."

The Duke of Montenegro has been busy fighting the Southern Alliance recently, so naturally he has no time to take care of Levi. For a big shot like him, there are more important things to do than killing Levi.

Levi took this opportunity to develop in a low-key manner.

Although he already has the strength to stand at the top of this era.

But there is no corresponding popularity and influence at all.

This is exactly the effect Levi wanted to achieve.

He doesn't want to be a dead legend, he just wants to live a good life.

…

The year 1010 of the Holy Hui Calendar, the month of the north wind.

The war started by the Duke of Montenegro has swept across the country.

After the Southern Coalition was formed, it finally stopped the Duke of Montenegro's overwhelming attack, especially the other dukes who had been neutral all along also took action. After learning of the Duke of Montenegro's ambitions, they had to take action.

However, it wasn't long after these dukes were gone.

Something unexpected happened.

First, a duke in the western region suddenly died at home. His death was horrific and it was suspected that he had been attacked by an evil spirit.

Not long after, another duke from the south also suddenly went mad on the battlefield with the Black Mountain army and attacked indiscriminately. While inflicting heavy damage to the Black Mountain army, he also severely damaged his own army and then disappeared.

Apparently, the southern duke was also attacked by evil spirits.

For a time, people were in panic.

These two dukes are both great knights.

Moreover, they are not those weak knights. As a still powerful ducal family, their breathing techniques are absolutely first-class.

Such beings were attacked by evil spirits and died suddenly or went crazy.

Moreover, it all happened not long after he went down to deal with the Duke of Montenegro.

This doesn't seem like a coincidence.

At this time, everyone remembered that the king and Knight Edward seemed to have died suddenly and strangely.

Gradually, rumors began to spread.

"The Duke of Black Mountain controls the power of terrifying evil spirits. For anyone who dares to go against his will, he will let the evil spirits invade the other party and torture them to death!"

Even the great knight was killed by the evil spirit.

People simply could not imagine what kind of existence could stop the evil spirits and stop the powerful Duke of Black Mountain.

There were frequent rumors of evil spirit invasions in the camp of the Southern Nobles' Coalition.

However, the Montenegrin army seemed to be unaffected at all.

This undoubtedly confirms everyone's speculation.

The Duke of Montenegro began to be called the "Devil Duke".

Some people say: "The Duke of Montenegro made a deal with the devil of hell in the legend, and was bewitched by the devil, so he launched an unjust war of aggression."

Some people say: "The devil wants to use evil spirits to create chaos and fear in the world, and eventually turn the world into hell."

The soldiers of the Southern Nobles' Coalition were in constant fear.

Now that the evil spirit has appeared and the snow demon has appeared, even if the Devil Duke appears, everyone feels that it is natural.

The unknown is the most terrifying.

For most soldiers, evil spirits are unknown horrors.

They may not even see each other and die inexplicably.

The Duke of Montenegro neither acknowledged nor denied the title of "Duke of the Devil". He just continued to do his own thing, recruiting more troops and investing more manpower and material resources into the war.

Since ancient times, most of the battles between nobles were minor ones. If I captured your people today, you can come and redeem them with money tomorrow. The conflicts between the two sides were generally not big ones, but trivial matters.

And this time, everyone can see that the Duke of Montenegro is serious.

Those captured soldiers can either surrender, take up arms and fight your former companions, or die!

The nobles condemned the crimes of the Duke of Montenegro, but it was just condemnation. The Duke of Montenegro's power made them feel frightened and terrified.

Later, the Iron Crocodile Arien family also joined the Black Mountain coalition, and the Iron Knight personally led an expedition to the south.

This seemed to be a signal. Within just one month, half of the great nobles in the north chose to join the Duke of Montenegro's coalition forces.

The northern nobles also realized that these southern nobles and royal families would not send troops to rescue them unless they saw the snow demon personally invade their territory. Everyone knows the principle of "the lips and teeth are cold", but it is extremely difficult to put it into practice.

At the rate at which the Snow Demon was moving southward, it was only a matter of time before the North was invaded.

So the northern nobles also thought it through. Since you southerners are unwilling to send troops, then we northerners will move to the south and wait together for the arrival of the snow monster.

If you southern nobles are in a bad mood, then we will be in a bad mood too.

Snow demons are undead creatures. Unless they are completely killed, their numbers will surely increase as they continue to move south.

When the Kingdom of Eternal Night can no longer hold on, it will be the end for everyone.

While in the Blackwater Valley, Levi couldn't help but feel nervous when he heard the rumors about the Duke of Montenegro, the "Devil Duke".

"Could it be that this Duke of Black Mountain really has mastered the power of the undead?"

“Damn it!”

"Even the top knights died at the hands of evil spirits. The Duke of Black Mountain actually has such a trump card?"

"And how does he prevent the evil spirits from attacking him?"

These are the doubts in Levi's mind.

This time he was determined not to go out and wander around until he became a great knight.

There are three brothers and Harris on guard, and there are two Vajra guardians, Demon Shark and Demon Mountain.

Levi was practicing in the shelter with peace of mind.

Now his role as lord in the Blackwater Valley is getting smaller and smaller.

In order to gain experience, Levi completely just let things slide.

Their status is similar to that of a shareholder in a modern company, and all they have to do is listen to the butler's report every once in a while.

The end of the month of the North Wind.

Inside Levi's body, a giant bloody whale floating above his heart opened its bloody mouth and swallowed up the water, boom!

The bloody giant whale expanded in size again.

Then, as the thicker black blood whale energy poured into Levi's limbs, bones, internal organs, Levi stretched his body and exhaled a breath of turbid air.

"The blood whale has reached the seventh level."

Levi——

Blood Whale Breathing Technique: Level 7 (1/50000), Special Effect: Top Endurance

…

"Top-level endurance, this is already the limit of human beings. If you can break through this shackles, you can become an almost inhuman existence like the Great Knight."

"Top defense, top endurance, top strength, top speed, four top attributes, the embryonic form of a polygonal warrior has been formed."

The Blood Whale Breathing Method is indeed an excellent quality breathing method with fifty-six little man patterns. There is no limit after the seventh level, and you can continue to grind it out, which makes Levi overjoyed.

After all, endurance-type breathing methods are relatively rare, and it is more troublesome to break the limit. The most common and easiest breathing method to break the limit is the strength-type breathing method.

"Don't be complacent, keep working hard!"

Levi had no pride or laziness at all.

He knew very well that this world where supernatural powers existed was full of hidden talents.

What you see is just the tip of the iceberg.

Snow demons and evil spirits are just the lowest level creatures among the demonic creatures.

It can pose such a huge threat to the knights or even the great knights who are considered to be powerful in people's eyes.

Even if those powerful demonic creatures cannot destroy the world, they can destroy a city in a single thought.

He is still too weak!

If you want to live longer and witness more beautiful scenery, you need stronger strength. There is no strongest, only stronger!

Be it a knight or a wizard, no matter if the cat is black or white, as long as it can make Levi stronger, he will accept it.

As the winter month arrived, the Blackwater Valley was covered in silver and the land was frozen for thousands of miles. A thick layer of ice also formed on the Blackwater River.

Apart from the transaction with Earl Yinshan, Levi spent all his other time studying the Black Snake Breathing Method. With enough Black Snake secret medicine, he finally mastered the Black Snake Breathing Method to the seventh level before the new year arrived.

Levi——

Black Snake Breathing Technique: Level 7 (Ultimate, Breakable), Special Effect: Top Defense

…

In Levi's heart, the black snake seed stood tall and straight, like a giant python circling the world. The black snake seed, which had reached the seventh level, was no longer the vague snake-shaped mist. Levi could see the illusory scales and the powerful snake body.

"It's becoming more and more real." Levi said to himself.

He looked at the painting hanging on the wall of the shelter.

In the picture, a black snake holding a candle is coiled majestically, illuminating all directions.

The current black snake seed is like a mini version of the black snake holding a candle.

"For a knight to advance to a great knight, the life seed needs to undergo the first transformation. After this transformation, the quantity and quality of the black energy will be greatly improved. It can even be released to fight the enemy outside the body. If you master it well, you can also wrap the black energy around your weapon, or even transform it into a weapon. For example, the Pale Shadow has a very exquisite control over the black energy. Not only can he release it to transform it into a ghost claw, he can even condense the black energy into a dagger and shoot it out to fight the enemy."

"As for the Demon Shark and Artos, their use of the black energy is relatively superficial. They can only simply wrap it around their weapons to fight the enemy. They are much worse than the Pale Shadow."

"From some information I got at the Shining Tavern, there is a special combat technique in this world that uses black energy. However, this combat technique is much rarer than combat techniques using weapons or fists and feet. It is basically hard to see. Even Earl Silver Mountain does not seem to have mastered the special black energy combat technique."

"If I want to acquire the fighting skills of Black Qi, I may have to learn from Pale Shadow."

"Now, begin the transformation."

Levi looked at the black snake seed on the heart.

The next moment, countless black air emerged from the body of the black snake seed, wrapping it up and turning it into a black cocoon.

"Come on, let me see the limit of Black Snake!"
