As long as the soul fire is not completely destroyed, these undead creatures will not really die. They can completely draw strength from the undead half plane and condense their bodies.

However, death, through flexible fire reorganization, consumes a lot of energy, and the source of these energy is the semi-plane of the undead.

After years of understanding the undead half-plane, Huo Yuhao gradually understood that the undead half-plane should be a space plane opened by Teacher Electrolux. In itself, it is not as stable as the main plane like Douluo Continent. To put it simply, the undead half-plane is more like a plane formed by pure energy bodies, and everything inside is composed of energy.

When creating it, Electrolux should have used an unknown method to inject it with an extremely stable energy, which is enough to ensure its self-sufficiency. When the undead creatures inside are released and fought, this stable energy will also be consumed.

Of course, this consumption is very slow.

However, if it continues to consume without replenishment, then sooner or later, the energy of the undead half plane will be exhausted, and at that time, the entire half plane will collapse.

Of course, this situation is almost impossible in reality.

The deeper the understanding of the magic of the undead, Huo Yuhao admired his deceased teacher, the holy god of the undead, and the natural disaster of the undead.

When Electrolux made the undead half plane, he not only gave it stable energy, but also built it into a wonderful cycle.

The function of this cycle is like the photosynthesis caused by sunlight after the plant absorbs water.

If the undead in the undead half-plane dies in the outside world, it will indeed lose some of its energy, but it is actually very little. So, how is the energy in the undead half-plane replenished? The way to replenish is actually very simple, that is, replenishing through the inlet and exit of creatures not in the undead half-plane.

Simply put, Huo Yuhao opened the undead half plane and walked in by himself. Then, all the energy in his body will be cleverly guided and changed in the undead half plane, and some of the breath will cause chemical reactions to occur in the undead half plane, thereby increasing the energy in the undead half plane. This reaction will no longer occur after the energy inside the undead half plane is saturated.

And what is the aura that Huo Yuhao brings in? That is, light!

The aura of light belongs to the outside world. The aura of light brought by the sunshine and the light in the heart are all sources of this energy.

Therefore, as long as the inheritor of the Undead Half Plane is a human or any creature with inner light and his own abilities do not belong to the darkness, then the Undead Half Plane does not need to worry about exhausting its own energy.

Huo Yuhao brought into the three soul tutor groups before! How much light power should be there for more than 3,000 people? Therefore, for this period of time, the energy in the undead half-plane has been in a saturated state.

But even so, Huo Yuhao would not do his best to consume the power in the undead half plane. After all, these undead creatures are the foundations in the undead half plane. If they consume too much, there will still be problems. What's more, their existence is equivalent to Huo Yuhao's own direct army. Although it is inconvenient to use on a normal battlefield, it is still very suitable for use in some special circumstances, such as in front of you.

What does an army need most? In addition to its own strength, the most important thing is to

handsome!

This is also the reason why Huo Yuhao asked the undead army to stop temporarily.

Although the purpose of the undead army is to consume these two soul tutor groups rather than defeat them, the consumption is also given priority, and the less you pay, the better.

The low singing began to sound from all directions, and corpse witches straightened their bodies in the undead creatures and raised their bone staff in their hands. The sound of spells they made was exactly the same as what Huo Yuhao chanted at this time.

The terrifying aura of the undead slowly rose, and a faint gray mist filled the entire forest. All creatures in the forest fled to the distance at the fastest speed, and did not dare to have any contact.

The terrifying power was spreading, and the invisible pressure kept suppressing the two soul mentor groups of Emperor Dragon and Evil Lord. They almost unconsciously increased the power of the soul mentor shield to the strongest state, because they didn't know how powerful the next supply would be, and even more so when it would arrive.

Consumption is not only physical, but also mental.

The biggest feature of undead creatures is that they are ugly and hideous. When any normal human faces a Wang Ling creature, their first reaction is fear and tension. In this case, their mental consumption will be much more violent than in normal battles, and this is also the goal Huo Yuhao wants to achieve.

This is the situation in front of us. Even Huo Yuhao himself did not expect that the deterrent power of the undead creatures could consume a lot of money on the two soul tutors.

The recovery of mental fatigue is even much slower than the exhaustion of soul power.

The two soul tutor groups were attacked by Huo Yuhao and Tang Wutong many times, and so many people were destroyed. They had long been frightened. At this time, facing the undead creatures, why are they not afraid?

Xia Xuanchen and Xu Tianyuan had clear ideas in their minds. They actually understood that the reason why the enemy hidden in the dark used these undead creatures to attack was that they did not expect these undead creatures to defeat the two beast king-level soul mentor groups. The real purpose should be to force them to fly back into the air.

Since there is such a purpose, they must have made arrangements in the air. If they were evil soul masters, those evil guys would probably be more than two of them.

Therefore, the two soul tutor leaders are very calm now, and they can only wait and wait for the enemy to appear on their own initiative. They didn't see these undead creatures. However, they obviously ignored the psychological changes of the ordinary soul tutors under them at this time.

The lengthy spell lasted for a minute, and then a large amount of gray airflow rushed from all directions towards the coordinated defense shield formed by the two soul tutors.

There was no need for commands at all, and various soul guide attacks broke out almost immediately, trying to disperse these gray airflows.

However, what surprised the soul masters of the two soul tutor groups was that all their attacks did not have any effect on the gray airflow.

Yes, it has no effect, nothing at all.

How is this possible? This idea appears in everyone's mind almost at the same time.

Then they found that the gray airflow had stopped after spreading in their direction for a distance, and then slowly landed on the ground without invading their defensive positions.

The soul tutors had just breathed a sigh of relief, and then their eyes widened.

With a serene sound, the corpses on the ground, which had already become bones and minced meat slowly condensed and reshaped under the nourishment of the gray airflow. They turned into skeletons and zombies and climbed up from the ground.

You should know that there were tens of thousands of undead creatures who died on the battlefield and under the soul guide. At this time, when these undead creatures began to resurrect, their originally empty vision was almost instantly filled with undead creatures.

What's even more terrifying is that in the hearts of every soul tutor, there is a feeling of immortality in the undead creatures, which is the most terrifying thing.

There are certain restrictions on the immortality of undead creatures, but the soul tutors don’t know it! They didn’t notice that among these resurrected undead creatures, there were actually no powerful undead creatures like the most powerful abhorrent knights before, only lower-level undead creatures such as skeletons and zombies.

There is no doubt that people will burst out with powerful power under fear.

Therefore, the next moment, the combat power of the two soul mentors burst out in full swing.

A series of dazzling lights continued to bombard the undead creatures with dazzling tail flames, tearing large and large pieces of undead creatures into pieces.

Those skeleton soldiers and zombies often fell into ashes in the light just after taking a few steps.

Countless soul tutors were roaring and roaring, bursting out the strongest soul tutor they could use in the most violent way, attacking wildly, raging.

A violent energy storm was set off within the sight line and a terrifying soul guide

Lines and soul guided shells have completely turned this area into a death zone.

There are no more corpses. After almost all the undead creatures fell down again, their bodies turned into ashes and were annihilated. Even the earth slowly sank under such terrifying attacks.

If you look down from the sky, you can see a huge ball of light. Nothing else can be seen.

At the beginning, Xu Tianyuan and Xia Xuanchen were still very pleased with the attack power of their two soul tutors. But soon, they felt something was wrong. The attack power was too strong, and their morale seemed to be a little wrong. Not only was it high, but it was also mixed with some other things.

Fear? Xia Xuanchen soon discovered that some of his soul tutors actually showed fear and madness in their eyes.

He finally woke up, but unfortunately, his awakening was still a little late.
