In the narrow space, the nearly condensed death energy is constantly rolling, with the power of capturing people. The faint fire light around can not reach the deepest part of the death energy, but can only print the faint outline of the internal creatures.

A huge shadow is in the center of death energy, constantly accepting the changes of death energy to its body. With the dull breathing, its momentum is more and more intense, and there is a growing trend.

If a caster who is good at magic ceremony comes here, he will be shocked by the scene in front of him. Under the function of the ceremony, death energy continuously gathers here, making the biological benefits of the ceremony center.

Conventional ritual can't achieve this effect. Only those powerful necromancers can integrate the Necromancers into the ritual.

In the upper space of the evocation tower, a special ceremony takes place here. On the periphery of the ceremony, rod, as the leader of the ceremony, is watching all this happening, and constantly releases his own death energy into the whole ceremony.

The existence of God level necromancy has enabled rod to master a large number of necromancery rituals related to it. Relying on the power of rituals, he has promoted the rank of undead creatures. Among all the necromancery rituals, he is already the top one.

There are not many necromancers who are qualified to guide the ceremony in front of them. Relying on their own energy of death, they can forcibly upgrade the ranks of their undead creatures. This kind of ceremony has very high requirements for the Necromancers themselves, and the existence of divine level spiritualism undoubtedly endows rod with such ability.

The shadow in the center of the ceremony is the Centaur leader under rod. At this time, it is accepting the promotion of the ceremony for its strength.

Before that, after constant battles, according to rod's perception, the rank of the Centaur leader should reach about level 5 and level 8. Because of this, with the help of the ceremony, rod intends to let him directly break through the limit of level 6 and enter the ranks of epic creatures.

In rod's impression, high-level undead creatures have two different promotion directions. One is like a ghost dragon, which is covered with a large amount of netherworld energy, and can rely on the netherworld energy to inflict serious negative damage on the enemy in battle. The other is like a terror knight, which fights on its own basic attributes.

For these two different ways of promotion, rod can take the initiative to choose. According to rod's choice, the subsequent Centaur leader will also get the corresponding expertise after promotion.

Because the Centaur leader is good at close combat, rod does not let him have the body shrouded by the energy of the nether world, but let him obtain more powerful basic attributes, and similar to the terrorist knight, he has the attack expertise that can trigger a fatal strike.

Under the guidance of rod, the energy of death around him kept pouring towards the Centaur leader in the center. His body became bigger and bigger, and his body, which had been frozen, became swollen at this time. A power belonging to higher-level creatures began to appear on him.

At this time, the potential of death knight is undoubtedly reflected in the Centaur leader. In rod's perception, the Centaur leader at this time has entered the ranks of the sixth level creatures, and it is not as simple as just entering the sixth level, at least reaching the level of sixth level and fifth level.

Before upgrading the level of Centaur leader, rod first promoted the level of vampire, but the effect was not ideal. He only upgraded the Vampire from level 5 and level 2 to level 5 and level 9, and did not promote its level.

As a result, the effect of the promotion ceremony on the vampire is far less than that on the Centaur leader.

Rod understood that the promotion of undead's rank is largely related to their potential. The greater the potential, the greater the promotion.

The Centaur leader with heroic identity has the same potential as other heroes. He has gone beyond the limit of his own kind, and even reached an infinite degree. He just needs to match the will of the hero. Even so, the potential of the hero is still beyond the ordinary creatures.

No creature can surpass the existence of heroes in its own potential. When they grow up, they will have very high-level creatures, such as dragons and unicorns. As long as heroes are born in their groups, they will be equivalent to the emergence of top legendary creatures.

Under the function of the ceremony, rod successfully advanced his important undead creatures. During this period, because he realized that there was a lack of spiritual control, rod absorbed a lot of magic drugs by virtue of the effect of aromatic secret method, which met the requirements of controlling undead creatures.

Soon, the energy of death on the spot was absorbed by the Centaur leader in the center, and the whole ceremony was coming to an end.

When the dark fog completely dissipated, the fire from the tower wall lit up the field again, and the Centaur leader who was promoted was in front of rod.

Rod's impression of the huge Tomahawk was hung by the Centaur leader at his waist, shining with bright glow in the light of the fire. Compared with the Centaur leader's huge size at this time, these two tomahawks were extremely suitable when they were held in his hands.

What exists in the Centaur leader is not the breath of any dark energy, but an unstoppable momentum, which belongs to the powerful momentum of high-level creatures.

By virtue of the promotion ceremony in the divine level spiritualism, rod promoted his Centaur leader to the sixth level. However, his later promotion exceeded the limit of this ceremony. It's not a simple thing for the undead to get the legendary level. There are few other ways to achieve it except to transform the legendary creature's corpse at the beginning.

Among the undead creatures, few legendary creatures are born. Even the powerful ghost dragon is only at the top of the sixth level. How long will it take to become a legendary creature.

At this time, it seems that the legendary undead really controlled by rod is only the netherworld sea monster in the water element plane. The spiritual imprint on the netherworld sea monster is still derived from the effect of the mother of the dead.

When he thought of the legendary undead, rod knew that his ability to control the spirit was not enough. Even if there was a magic drug factory, he didn't know how long it would take to make enough magic drugs to improve his ability to control the spirit to his satisfaction.
