Hearing this, Fang Mu stepped forward and pulled hard on the lock on the iron cage door.

But when he pulled it, Fang Mu discovered that the lock had been welded with gray-green rust because it was infected by the dead air.

It is difficult to open the iron cage from the outside.

Fang Mu frowned and summoned Feng Rang of Blood, and a large amount of bloody mist suddenly enveloped Fang Mu.

Fang Mu's short black hair turned blood red and hung down to his neck and shoulders, and the black goat's head wrapped in bubbles in his eyes gently rotated.

The hell prajna who was contracted by Fang Mu felt an inexplicable pressure.

The three ferocious undead creatures, the Grave Hunter Corpse and the Giant Violent Butcher, all nervously huddled their arms together.

Fang Mu used his hands to pull the iron cage, but without using much force, the railings of the iron cage were torn off one by one.

The shackles on the wrists and ankles of Grave Hunter and Violent Butcher are made of the same material as the iron cage.

Therefore, Fang Mu pulled and scrapped these shackles without expending too much effort.

The three Grave Hunters and the Giant Violent Butcher who were released stood obediently in front of Fang Mu like statues because they were controlled by Hell Prajna.

The Violent Butcher was okay, his body was covered with a thick layer of corpse skin.

The skins of these corpses were covered with moss, just like a piece of clothing.

But there was no cover on the bodies of the three grave hunters, which seemed a bit inconsistent.

Dead air is infective to many materials and will cause many materials to rust.

Ordinary clothing is not suitable for an undead creature covered in death energy.

Under normal circumstances, beast masters contracted with immortal beast masters will not choose to wear clothes for the beast masters.

First of all, the undead-type beast masters do not have spiritual power and cannot use spiritual weapons.

Wearing armor that is too thick on an undead beast will reduce the ability of the undead beast to move.

Secondly, in some official competitions and battle network duels, beast masters are not allowed to wear protective gear with defensive effects.

However, there is a type of fungus that can coexist with undead beasts.

The spores of this fungus will absorb the energy in the soul fire of undead creatures to regenerate, change color according to the undead creatures' knowledge of themselves, and form different styles of clothing.

This fungus is called "Death Dress".

Because there are relatively few people who have contracted undead beasts in the Dragon Federation, and the fungus "Death Dress" often appears in ancient battlefields, the price is not expensive.

Fang Mu has been purchased in advance on Anji.

The bacteria "Death Clothes" live in symbiosis with undead creatures and have no defensive effect.

Therefore, it is not regulated by any major events and can be used at will.

It's just that if the fungus "Death Dress" wants to remain active, it needs to consume a certain amount of wood element medicine to water it every day.

This is a huge expense for many beast masters who have contracted undead beast masters.

After all, a beast master who contracts an undead beast has to use life energy to cleanse his body of the infection of death, which is already a huge expense.

Fang Mu stepped forward and planted the bacteria of the "Death Dress" on the bodies of the three Grave Hunter Corpses and the Giant Violent Butcher.

Then a bottle of wood element potion with a purity of 70% was poured on the strains of "Death Dress".

Nourished by the energy of death and wood elements, the "Death Dress" strain immediately began to take root and divide.

Hell Prajna continues to sip the dead souls and improve his level.

While Fang Mu was planting the "Death Dress" strain, Hell Prajna's rank had been raised to Silver Level 4.

Undead creatures such as the Violent Butcher, whose evolutionary path is not easy to determine, can only obtain an exclusive characteristic after being promoted to the gold level.

Only then can the evolution route be determined based on skills and exclusive characteristics.

So Fang Mu directly fed the immortal crystals produced by the suction to the violent butcher.

Watching helplessly, the violent butcher's rank continued to rise, and he soon broke through the silver rank.

And under the nourishment of 100% pure death energy, the quality directly leaps from ordinary quality to elite quality, reaching the level of perfect quality.

Fang Mu didn't have much expectations for the Violent Butcher.

Before the evolutionary path is determined, as long as the Giant Butcher can be a good front-line player, it is enough in Fang Mu's opinion.

In the end, the violent butcher gave Fang Mu a huge surprise.

[Beast Name]: Violent Butcher

[Royal Beast Species]: Macrozoidae/Gremozoidae

[Beast Control Level]: Silver Level (2/10)

[Beast Control System]: Undead System

[Beast Control Potential]: Gold Level

[Beast Control Quality]: Perfect quality

Skill:

[Gluttony]: Quickly recover one's own injuries by devouring corpses. When there are no corpses to devour, priority can be given to devouring one's own flesh and blood to recover fatal injuries.

[Flesh Trap]: When being beaten by an external force, it can turn its own flesh and blood into a puddle to imprison the target.

Exclusive features:

[Flesh and Flesh Arms]: Devour corpses that are not higher than one's own life level, and can hide the substances in the corpses in the body or fix them on the body surface, becoming part of the body.

Evolution route:

1: Fusion Body Butcher, 2: Sickle Butcher, 3: Giant Bone Butcher.

Since the level of Hell Prajna is only Silver Level 5, the Giant Butcher, as the undead creature controlled by Hell Prajna, cannot have a higher level than Hell Prajna.

But after Hell Prajna reaches the tenth silver level, the violent butcher can easily be promoted to the tenth silver level with these death energy crystals.

After being promoted to the Silver level with perfect quality, the Violent Butcher gained new skills and exclusive characteristics.

The silver-level skill [Flesh Trap] is very unique. When being beaten by an external force, it can fuse the target's hands, feet, and even the head full of sharp teeth into its own flesh and blood.

The source of life of undead creatures is the fire of the soul, and the physical body is just a shell.

There is no need for the Violent Butcher to use his body as a prison for fear of being destroyed by the enemy.

If the body is destroyed, it can be restored by swallowing some flesh and blood.

It was like fighting a wolf-like beast. As soon as the wolf-like beast's front paws came over, it was trapped in the body of the violent butcher.

The same goes for biting.

This allows the Tyrant Butcher's frontline to control multiple targets at the same time with the silver-level skill [Meat Trap], becoming a mobile universal glue.

The flesh and blood of the Violent Butcher contains high concentrations of dead air, mold poison, rot poison and other toxins.

These toxins will infect the target's flesh and blood while being controlled, threatening the target's life.

The exclusive characteristic [Flesh Arms] allows the Violent Butcher to transform his body in the process of devouring flesh and blood.

For example, after devouring the body of an eagle-like beast, the Violent Butcher can hide the eagle's claws inside the flesh or as weapons on the body surface.

If Fang Mu lets a tenth-level silver-level violent butcher devour the corpses of a hundred iron-skeletal wolves.

The Violent Butcher can use the hard spine of the Iron Skeleton Wolf to build its own skeleton, and make its palms and arms covered with sharp teeth.

Damage the target during combat.

This exclusive feature [Flesh Arms] allows the Violent Butcher to gain unlimited possibilities through foreign objects.

Based on the current skills and exclusive characteristics, the most suitable evolutionary path for the Violent Butcher is the Fusion Butcher.

When the Violent Butcher advances toward the gold level, Fang Mu can feed the Violent Butcher with Blood Aged Brew to officially evolve the Violent Butcher into the Fusion Body Butcher.

Next, Fang Mu only needs to let the violent butcher quietly absorb the death energy crystals to increase his rank.

Fang Mu turned his attention to the three grave hunting corpses.

The corpse-hunting skills and exclusive characteristics of these three graves are exactly the same, but they differ in their evolutionary routes.

The evolutionary routes selected by Fang Mu are the pregnant mother, the nanny and the boy.

Fang Mu is most interested in the grave-hunting corpse that can evolve into a grave-pregnant mother.

He immediately took a crystal bottle of blood-colored aged wine, and first fed the death energy crystals to the corpse hunter who could only evolve into a grave-sacrifice pregnant mother.

Open the crystal bottle and let Hell Prajna control the drinking volume of the Grave Hunter according to the state of the Grave Hunter.

After Fang Mu finished feeding the grave hunter corpse, which could only evolve into the Grave Sacrifice Pregnant Mother, Fang Mu also performed the same operation on the other two.

Fang Mu wanted to see how different the exclusive characteristics and evolution routes would be after the "Three Treasures of Grave Sacrifice" of the Grave Sacrifice and Corpse Hunting Corps completed their evolution.

The death energy crystals fed to the Grave Hunter Corpse are not only absorbed by the Grave Hunter Corpse itself, but part of it is also sucked away by the "Death Dress" bacteria.

The "death dress" bacteria that had just taken root in the three grave hunting corpses differentiated rapidly.

At this time, the grave hunter corpse that can evolve into a grave-pregnant mother grows long gray-green hair and has a high bulge in its abdomen.
