A group of low-level demons were driven to the pivotal formation, and then they were cut off their throats and bleeding one by one by the dark slaves. These dark slaves had no combat power, but they were more ruthless than anyone else when they were offering sacrifices.

The small dagger that was less than a slap was pulled in his throat and the blood was released. The low-level demons were directly paralyzed by the poison attached to the small dagger. They knelt on the ground and could only watch the blood flowing out of their throats.

With the nourishment of these demon blood, the lines of the magic array began to be dyed black and emitted a faint red light.

This is not the end, and the dark slaves kept robbing 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 on the operating magic circle became more and more intense.

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

Hearing Deka's sigh, Yang Chenyu couldn't help but glar at Deka. This guy was always a demon, and his thoughts were still so evil.

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

As the red light of the mage continued to shine, the blood of tens of thousands of low-level demons was completely dried up. At this moment, a black cloud appeared above the mage, gradually turning into a huge eyeball, looking at the mage.

When the huge eyeball appeared, Yang Chenyu immediately covered up all the auras in his body. He had seen it before and knew that this was the abyss consciousness.

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

Countless abyss aura poured down from the huge eyeballs and poured onto the dynasty array. Then the dynasty array began to operate, and countless magic patterns appeared on their own and drilled into the ground.

Yang Chenyu looked over and found that these magic patterns were somewhat similar to those formed in the demon's body. In just a few breaths, the magic patterns formed a channel directly to the earth vein underground. Countless flame energy in the earth vein was extracted and stored in the operation array.

Seeing this, Yang Chenyu nodded. This operational magic array is somewhat similar to the mountain protection magic array he set up.

Although the energy channel of the mage was formed, the giant eyes above the sky also began to collapse.

After that, Deka hurriedly ordered the demons to push the building materials into the range of the operation array. Under the action of the operation array, the stone bricks were piled up on their own, starting from the flat ground, rising continuously, forming buildings.

In less than a hundred breaths, a majestic castle stood up.

This demon's method is quite powerful. If this move can be used in other worlds, the demon may have a great advantage.

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

These energy pools gathered flame energy extracted from the earth's veins, which looked like a pool of fiery red water, but a small evil demon accidentally fell down, and in the blink of an eye it turned into ashes, and there was not even a single bone residue left.

"Master. These flame energy are condensed and are exclusively used by various buildings." Seeing Yang Chenyu's eyes, Deka hurriedly introduced it. Judging from the expression on its face, this flame energy may not even dare to go down to take a shower.

A castle requires a lot of buildings. It is not just the main tower and the city wall.

Yang Chenyu brought a group of small heart-fighting demons into the main tower. These little guys have been supplemented a lot during this period, their bodies have been increasing, and their strength has also increased day by day. If Babubala hadn't controlled them, he would have sucked the pitiful demons long ago.

Deca didn't have the chance to rest. As a former great demon on the third level, Deca has a lot of experience in castle construction.

Seeing the master enter the main tower to rest, Deka took the dark slaves and started building according to his intentions.

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

Although demons have a long lifespan and will not die due to hunger, long-term hunger will also cause the demons' strength to continue to decline. Regarding this, even top-level existences like the Demon Lord are no exception.

Once, a demon king invaded other worlds and was accidentally besieged. In the end, he was sealed for hundreds of thousands of years without food or drink. Finally, when the demon believers he tempted rescued it from the seal, the demon king's strength had deteriorated to the level of an intermediate demon.

Of course, after devouring a large number of flesh and blood souls, the demon king quickly recovered his strength, but it can be seen that hunger has indeed had a great impact on the demon.

Therefore, food rooms must be built in any castle to provide enough food.

In addition, there are also various demons' residences, as well as defense magic arrays, forging rooms, hatching pools, etc.

The construction of the food room does not take much time, and in fact, all buildings do not take much time to build. After all, with the support of the magic circle, the castle has strong self-construction ability. It only needs to transport materials and the dark slaves to engrave the required magic circles.

Therefore, after Yang Chenyu learned everything he learned after coming to the Abyss World in the main tower for some time, Deka came to report that the food room had been built.

Yang Chenyu is very interested in these things. The saying that stones from other mountains can be used to polish jade is not just a joke.

Not to mention anything else, after coming to the Abyss World, Yang Chenyu's heart of Tao has become brighter during this period. In addition, he also has some understanding of the essence of the Abyss World. These things have a lot of effect on pursuing the Great Way after Yang Chenyu returned to the Dharma-Ending World.

When others come to the Abyss world, they may see the barrenness, danger, terror, threat, and the selfishness, cunningness and cruelty of the Abyss world.

But what Yang Chenyu saw was some things from the origin of the abyss world. Of course, according to Yang Chenyu's point of view, the abyss world's abyss world is inconsistent with him, and even goes against him, but this does not hinder Yang Chenyu's pursuit.

The food room is a circular building with a wide area. A plaque is placed above the gate by Deca, with an image of a maggot on it.
