A low-level demon was driven to the operation circle, and then the throats were cut and bloodied one by one by the dark slaves, these dark slaves had no combat power, but they were more ruthless than anyone else when it came to sacrifice.

The small dagger that could not be slapped was pulled on the throat like this, and the blood was released, and those low-level demons were directly paralyzed by the poison attached to the small dagger, kneeling on the ground, and could only watch the blood continue to flow out of the throat.

With the nourishment of these demonic bloods, the lines of the circle began to be soaked in black, emitting a faint red light.

And that's not the end of it, the Servants of Darkness keep bringing in new low-level demons to cut their throats and bleed.

As the number of low-level demons kneeling on the ground continued to increase, the red light on the lines of the operating circle became more and more intense.

Seeing that the operation circle began to move, Deka couldn't help but sigh: "It would be nice if there were some intelligent creatures involved in the sacrifice." ”

Hearing Deka's sigh, Yang Chenyu couldn't help but stare at Deka, this guy has always been a demon, and his thoughts are still so evil.

But then again, if you really add some intelligent creatures, such as humans, elves, etc., the effect of sacrifice will indeed be much stronger.

As the red light of the operation circle continued to shine, the blood of tens of thousands of low-level demons was drained, and at this moment, a black cloud appeared above the operation circle, which gradually turned into a huge eyeball and looked towards the operation circle.

When Yang Chenyu appeared in that huge eyeball, he immediately covered up all the aura around him, he had seen it before, and knew that this was the appearance of the abyss consciousness.

The huge eyeball glanced at the operating circle below, and suddenly the tens of thousands of demons turned into ashes in an instant, and it seemed that with just one glance, the demon's soul and demon core disappeared.

Countless abyssal breaths poured down from the huge eyeballs, pouring into the running circle, and then the running circle began to operate, and countless magic patterns immediately emerged on their own, burrowing into the ground.

Yang Chenyu looked over. However, it was found that these magic patterns were somewhat similar to the magic patterns formed in the demon's body, and in just a few breaths, the magic patterns formed a direct passage to the leylines underground, and countless flame energy in the leylines were extracted and stored in the operation circle.

Seeing this, Yang Chenyu nodded. This operation circle is somewhat similar to the mountain protection circle that he has set up.

While the energy channels of the operating circle are formed. The giant eye above the sky also began to crumble.

Deka hurriedly ordered the demons to push the building materials into the range of the operation circle, and under the effect of the operation circle, those stone bricks were piled up on their own, starting from the flat ground and rising continuously, forming buildings one after another.

In less than a hundred breaths, a majestic castle was erected.

This demon's method is a bit powerful, if this trick can be used in other worlds. I'm afraid the devil will take advantage of it.

Yang Chenyu took the lead in entering the castle, and at this time, in addition to the main tower and the city wall, there were only about a dozen energy pools in the castle.

These pools of energy gathered fire energy drawn from the leylines, and they looked like pools of fiery red water, but a small bad demon accidentally fell down. As a result, it was reduced to ashes in the blink of an eye, and there was not even a single bone residue left.

"Master, this flame energy is condensed and used exclusively for all kinds of buildings. Seeing Yang Chenyu's gaze, Deka hurriedly introduced, judging from the look on its face, this flame energy was probably a little afraid that even it would not dare to go down to take a bath.

A castle requires a lot of buildings. It's not just the main tower and the walls that are enough.

Yang Chenyu took a group of little heart snatchers into the main tower, these little guys have made up a lot during this time, their size has been increasing, and their strength is also increasing day by day. If it weren't for Bab Bala to restrain them, I'm afraid that those poor demons would have been sucked out of their brains long ago.

Deka didn't have a chance to rest, as a former great demon of the third level, Deka had a lot of experience in castle construction.

Seeing his master enter the main tower to rest, Deca took the dark minions and began to build according to his own wishes.

Originally built was a food house, which was the main building used by the castle to attract wild demons and maintain their combat power.

Although demons have a long lifespan and do not die of hunger, prolonged starvation can also cause the demon's strength to continue to decrease, and even a top-level being like the Demon Lord is no exception.

There was also a demon lord who invaded other worlds, was accidentally besieged, and was finally sealed for hundreds of thousands of years, without food or drink, and finally by the time the demon believers it tempted rescued it from the seal, the demon lord's strength had degraded to the level of a mid-level demon.

Of course, after devouring a large number of flesh and blood souls, this demon lord also quickly regained his strength, but it can be seen that the impact of hunger on demons is indeed not small.

Therefore, any castle must have a food room to provide enough food.

In addition, there are various demon abodes, as well as defensive circles, forge houses, hatching pools, and so on.

It doesn't take much time to build the food room, and in fact all the buildings don't take much time to build, after all, with the support of the operation of the magic circle, the castle has a strong ability to build itself, and only needs to bring in materials and the dark minions to inscribe the required magic circle.

Therefore, after Yang Chenyu recalled all the things he had learned after coming to the abyss world in the main tower, Deka came to tell him that the food room had been built.

For these things, Yang Chenyu is very interested, and the sentence that the stones of his mountains can attack jade is not a joke.

Not to mention anything else, after coming to the abyss world, for such a period of time, Yang Chenyu's Dao heart has been sharpened more brightly, in addition, there is also some understanding of the essence of the abyss world, and these things have a lot of roles in pursuing the Great Dao after Yang Chenyu returned to the end of the world.

When others come to the abyssal world, what they see may be the barrenness, danger, terror, and threat of the abyssal world, and the selfishness, cunning, and ferocity of the demons.

But what Yang Chenyu saw was something on the origin of the abyss world, of course, according to Yang Chenyu's point of view, the avenue of this abyss world did not match his own, or even went against him, but this did not prevent Yang Chenyu from pursuing.

The feeding room is a large circular building with a plaque above the gate with an image of a maggot on it.

After asking Deka, Yang Chenyu knew with a smile that it turned out that this was to let the demons know the name of this building, but for most demons, they are unlearned, and killing people is a good hand, but such a thing as demon writing does not exist in the abyss world. (To be continued)
