After Ji Feng got this castle, the first thing he did was to try to restore the mystery lock circle of the entire giant demon castle and modify the control authority in it.

After the modification of the Enigma Lock Circle was completed, Ji Feng went deep underground and entered a constant state, so that the creation clone in the shape of the phantom of the World Tree in the sky and the creation system in his body could be promoted to level sixteen as soon as possible.

After five days and five nights, Ji Feng awoke from his constant state and came from the ground to the surface.

At this time, there were basically no fifteen-level monsters in the giant castle that numbered more than fifty.

Some of the monsters and trolls are generally sacrificed, and when they blow themselves up, they are all dead.

Simply, there are more than 500 monsters of various varieties here.

Ji Feng asked them to first repair the entire interior of the giant demon castle, change the way the internal mystery lock circle entered and exited, and then restored the spider lair of the underground dome phantom, and also restored the demon church.

Then, let the remaining personnel in the castle go out to hunt.

The main thing is to look for small demons or other low-level monster cannon fodder from different places in the wilderness.

Himekaze needed them to perfect the castle's demographic arrangement.

Yellow Sand Dragons, Shadow Druids, Shadow Warlocks, and Bobcat Druids, they go out hunting other low-level monsters and catching small demons.

Ji Feng is waiting for the arrival of the little demon in the castle.

These monsters created by Ji Feng, they went out for three days and sent back more than a thousand little demons, as well as other low-level monsters in different quantities.

Ji Feng grabbed a little demon and pulled and prayed to it, but he didn't turn into a phantom and flew into the other party's body, so that the little demon who was targeted rose up with a layer of black mist on his body.

The black mist rolls on the surface of the little devil's body.

The body under the black mist was rapidly transformed.

Ji Feng saw that the little demon's body was transformed into a human form by the power of prayer pulled in the black mist, and then a stream of black gas filled the human-like body.

The human being has become a corrupted demon.

This demon man is two meters tall at this time, his strength is huge, like the Hulk in the movie version, and his skin is as hard as an alloy steel plate.

His movements are as fast as lightning, even if he is a fifth-level professional, his flesh and blood body has been strengthened by combat energy, which is already extraordinary, but in the face of the attack of the demons, there is still no way to react.

Ji Feng extracted sixteen units of matrix data information from the transformed demon body, and passed it to the creation clone, so that the demon automatically released a black assimilation aura, and all the fifty little demons in the vicinity were called into demons with a height of two meters and a human appearance.

Ji Feng looked at the fifty demons who had been assimilated, and knew that since the creation system in the creation division body was promoted, the more advanced the monsters that were transformed, and the fewer monsters of the same level that could be assimilated.

At this time, the Creation System was promoted to level 16, and the number of monsters of the same level that could be assimilated by the transformation or creation of level 16 monsters was only fifty at most.

The gap in one level was reduced from a hundred to fifty.

Ji Feng ordered these demons with the physical combat strength of the sixteenth level professionals to go out hunting, go to farther places to capture or forcibly enslave, and more low-level little demons or low-level cannon fodder monsters came over.

After Ji Feng saw these demons quickly leaving the giant demon castle, he continued to pull the power of prayer and flew into the body of another little demon.

A black mist emerges from the body of the little demon that is the target.

The little demon's body twisted rapidly in the black mist.

When the black fog dissipated, the little demon had turned into a demon general.

This demon warlord has the combat power of a sixteenth-level professional, but in addition to his own peerless melee fighting ability, he has no other spell-like abilities, but he can summon other low-level demon warriors to fight before the battle.

Seven hundred low-level demon warriors can be summoned and used as infantry.

Four hundred wolf cavalry-type demon warriors can be summoned, and when they form a battle formation to charge, even the battle formation composed of tenth-level professional demon warriors does not dare to hedge against them.

But if these demon warrior wolf cavalry lose their mounts, their combat strength is even inferior to that of ordinary demon warriors used as infantry.

Can summon a hundred Rampage Archers.

These rampaging archers, their arrows have special magical powers attached to them, and they can completely pierce through enemies below level thirteen.

Even if the enemy is wearing powerful combat armor or special magical defense items, the furious force of the arrow impact will carry the enemy back twenty meters away.

In this way, the enemy will have a lot of difficulty trying to get close to these rampaging archers, and they will not even get close, and they will be hit by the arrows of the other cooperative rampaging archers, and they will die completely.

After this demonic warlord appeared, a black aura bloomed from the top of his head.

The aura spread in all directions, quickly bringing fifty little demons into the aperture.

The fifty most powerful little demons within the range of these apertures screamed one after another, and a layer of black mist rose up from their bodies.

The black mist twisted, and the flesh and blood inside were constantly changing.

Soon, when the black fog dissipated, these little demons had turned into demon warriors one after another.

Ji Feng extracted sixteen units of matrix data information from the bodies of these demon warriors and passed them on to the creation clones.

Then he ordered these demon generals, who could summon other kinds of demons, to the outer wall of the giant demon castle, and were responsible for guarding the castle and preventing foreign enemies from sneaking in.

Ji Feng found that at this time, there were very few little devils on the field.

They were all imprisoned in underground cells.

Waiting for the arrival of other little demons or cannon fodder monsters.

Another two days passed.

Ji Feng waited for the prey brought by the demons, a group of small demons, and the number reached five hundred.

Ji Feng was very happy and extracted all the other little demons and cannon fodder monsters in the underground prison.

Ji Feng began to draw the power of prayer and transformed the little demon into a new sixteenth-level monster.

The first monster to be successfully transformed was a Spider Queen. Seeking Chinese

The upper body is the appearance of a beautiful dark elf, and the lower body is a huge spider, which can release a huge amount of dark magic power, turn into mist, fuse shadow energy, and sexually build a special shadow nest, playing different combat and trap roles.

The second monster to be successfully transformed is a ghost knight.

This one is no more than two meters tall, and its appearance resembles that of an elf, with a slender body, dark skin, covered with special patterns, exuding the energy fluctuations of the undead, and holding dual swords in both hands.

The third monster to be successfully transformed is a snowman.

This is a special elemental lifeform formed by the condensation of the water element and the power of frost, not only is its own level equivalent to that of a sixteenth-level professional, but the combat power actually exerted, as long as it is not out of the hot desert, the combat power they exert is definitely more terrifying than the combat power exerted by the ordinary three sixteenth-level professionals.

The frost power that freezes everything is enough to completely freeze the enemies in an area, all enemies at the level of the eighteenth-level Sacred Domain, and turn them into ice sculptures.

The fourth monster to be successfully transformed is a dragon guardian warrior.

This dragon guardian warrior is dressed in red armor, with thick limbs like earth dragons, and a humanoid human body on the upper body, but four extremely thick arms, wielding a magic weapon like a sword.

As the other party walked, there was a faint layer of black mist on his body.

This kind of black fog can block the exploration of spiritual power, and can avoid the depth of spiritual power.

With rough skin and dragon blood, it can defend against a quarter of pure physical attacks and a quarter of pure magical energy attacks.

His combat skills include combat charge, and the magic runes on the horse slasher have an armor-piercing effect, which can send out a demon-like spell-like ability, but it is a fast dragon spell, releasing a monstrous huge flame, turning a designated area into a sea of fire.

The fifth monster to be successfully transformed is a giant steel bear.

Five meters tall, huge and huge, between the shaking of fur, there is a huge sound of thunder and explosion, but when walking, the body is like lightning, from one direction to another.

The most important thing is that in addition to the thick hair, this steel giant bear has a layer of palm-sized scales on top of each other, and those magic grows like weeds from the cracks in the scales, and the scales can resist the attack of ordinary physical attributes and the damage of one-third of the spell energy.

When the Iron Bear attacks, if the enemy is very close to them, they will flash their bodies and appear directly in front of the enemy, and the huge bear paws with fierce electric light will bombard the enemy's body fiercely, paralyzing the enemy's body and turning the enemy's body into charcoal.

When the enemy is far away, they let out a roar, and the steel scales all over their bodies seem to be filled with a special liquid thunder light, making them say that they are on all fours and charge wildly.

At this time, the attack of the steel giant bear, as it galloped, like a huge locomotive that burned with flames and released the magnificent electric light, slammed into the enemy from afar.

The bear paw of the steel giant bear can also release the light of thunder, turning into a thunder giant claw to bombard the enemy fiercely.

Professionals below level 15 may be killed with one blow in the face of this attack.

The sixth monster to be successfully transformed is the Thunder Bear.

The Thunder Bear of this monster can condense and exert the power of thunder more freely than the Steel Giant Bear.

At this time, the Thunder Giant Bear is more like a four-meter-tall bear man.

His body was extremely strong, like a giant, his body was full of muscles, full of huge explosive power, and even near the hair around his body, there was a light condensed by the power of thunder shining.

The surface of the skin, the inner layer of the bear's hair, has a brilliant pale blue light that gathers the power of thunder, and can turn into energy that annihilates everything at any time.

The fur and skin of the Thunder Bear can be immune to all external thunder power attacks, and can even actively absorb foreign thunder power and transform it into its own thunder power.

At the same time, these skins and fur can also increase the thunder attack cast by the giant bear itself.

He can summon a clone, using his own form as the outer contour to condense the power of thunder and form a doppelganger-like energy body.

This energy body is the Thunder Bear Shadow Clone, which has one-third of its own attack and defense power.

This kind of shadow clone-like energy body can be condensed into a total of fifteen.

He can use a huge earth-shattering roar to let out a terrifying roar, just like the dragon's roar, not only can he cast the energy of the spell, but also increase the power of the dragon's power, deter the roar, and can also use the power of spirit and momentum to plunge all nearby enemies into panic and desperate fear, making them lose the power to resist.

He can unleash the Thunder Claw to unleash a special energy slash.

This energy light slash has five huge claws every time, and each energy claw has a five-meter-long half-moon arc of light.

He can even unleash a lightning storm with a very large range, turning a certain area where the enemy is located into a target, the dark clouds in the sky converge, and countless forked lightning bolts continue to bombard down, completely killing the enemy.

The seventh monster to be successfully transformed is the Naga Neng Warrior of the Deep Sea.

This deep-sea naga not only has a huge body and fast combat ability, but can also survive on land for a long time, and can even be active for a long time in places that lack humidity such as deserts.

The countless scales on the body of the deep sea Naga can shoot out like a fierce crossbow, bombarding the enemy from different directions.

It can condense into deep-sea whirlpools with a diameter of half a meter in the air around the body.

The shape of this deep-sea vortex is just a magical phantom, and it can't be like in the deep sea, it can instantly form a waterspout that roars across the entire sea area, and finally evolves into a water dragon, bombarding the enemy back and forth, but it can be turned into a vortex light curtain, swallowing any nearby energy attacks into it, and carrying out defensive effects, so that the enemy's attacks cannot hurt themselves.

After completing the transformation of this monster, there were already three hundred and fifty monsters of level 16 professionals on the field.

Ji Feng extracted one hundred and twelve units of matrix data information from their bodies and passed it on to the creation clone.

Subsequently, Ji Feng ordered some of the monsters present to go out hunting and capture more little demons and other monsters.

The other part is to act as a guard, protecting the entire giant demon castle.

The other part is to go to the small demon castle in the remote area occupied by Ji Feng to garrison and protect the safety of the small demon castle.

Then enter the depths of the underground of the giant demon castle, and enter the constant state.

After five days and five nights, Ji Feng broke away from his constant state.

At this time, the Rebirth System had been promoted to Level 17.

And Ji Feng also knew that from now on, except for the maximum number of monsters of the same level, no more than fifty, the little devil could no longer adapt to the transformation of the power of prayer.

If you want to transform a seventeenth-level monster, you must exclude the little devil.

The little devil will exist as real cannon fodder and food.

They won't be needed so urgently.
