Due to the presence of the ghost dragon, Rhodes did not encounter any obstacles or any battles, and returned to the territory of Verning.

Along the way, no flying creature dared to come after feeling the power of the ghost dragon, and could only watch the ghost dragon's figure quickly leave. Similar to the existence of the previous hero Thunderbird, it also belongs to a small number of existences on the entire battlefield.

Among the creatures that found the trace of the ghost dragon, there were also some creatures, after noticing the existence of the ghost dragon, their eyes showed some special looks, but they also did not dare to have any thoughts about the ghost dragon, so they could only write down the information about the ghost dragon in their hearts, and prepare to react it to the stronger existence.

After several days of continuous flights, the ghost dragon returned to the territory of Vilning.

During the flight, the ghost dragon did not feel any fatigue and maintained an extremely high speed. This is impossible for any other living being. Only the properties that the undead creatures give to the ghost dragon allow it to achieve this.

On the way, Rhodes also noticed two different dragon bones on the ghost dragon's body, so he recalled the changes that occurred in the ghost dragon's body when he was injured before, because of the contact with the death energy released by himself.

Thinking of this, coupled with the fact that the process of flying is relatively safe, and there is no need to worry about the attack of other creatures, Rhodes no longer waits, but releases death energy to the ghost dragon, wanting to continue to observe the abnormalities on the ghost dragon.

As Rhodes released the energy of death, an extremely obvious change appeared in the ghost dragon's body. More and more dragon bones began to transform into stronger forms, no longer having their original shapes, but becoming netherworld-like beings. The netherworld energy on the ghost dragon's body also changed accordingly with the transformation of the dragon bone.

In this process, although the rank of the ghost dragon has not changed, the momentum released around it has undoubtedly become stronger and stronger, and even Rhodes, who controls it, can also perceive it.

Just as these changes occurred in the ghost dragon, Rhodes suddenly realized something and looked at Rowling on the side.

Rhodes noticed that when the dragon bones on the ghost dragon's body began to transform again, the netherworld energy overflowing from the ghost dragon's body also increased.

For Rod, who has a legendary spiritualism, the enhancement of netherworld energy cannot have any effect on it, and Rhodes itself can resist the erosion of netherworld energy very well.

However, for Rowling on the sidelines, this is not the case. Until this time, Rowling's level of spiritualism was still only at the expert level, and she could only produce extremely limited resistance to the netherworld energy overflowing from the ghost dragon's body.

Before the dragon bone changed, Rowling was able to rely on the existence of spiritualism to resist the erosion of netherworld energy, but after Rhodes released death energy, the situation undoubtedly changed.

At this time, Rowling was no longer able to resist the erosion of netherworld energy, and under the effect of netherworld energy, Rowling felt extremely uncomfortable.

Even so, Rowling still didn't say anything to remind Rod, just looked at Rhodes on the side, silently bearing the erosion of netherworld energy.

If it weren't for Rod discovering the anomaly from the blood perception and stopping the release of nether energy in time, the pain on Rowling's body would have continued.

This discovery made it impossible for Rhodes to continue to release death energy on the ghost dragon, and he could only wait until he returned to Werning to continue to release it.

During the dragon's flight, Rhodes also tried to ask Rowling about the powerful spells Rowling had cast.

Before that, Rod had noticed these changes in Rowling, but he had never had the opportunity to ask him, and he took this opportunity to express his doubts.

What Rod didn't expect was that Rowling didn't have any clue about the appearance of those special spell-casting knowledge, and even after the battle, even if Rowling tried to cast spells again and make changes to them, it also couldn't work, and it seemed that she had completely lost her previous ability.

There may have been a lot of doubts in Rhodes' mind about this, but Rowling had a clear feeling that as soon as she entered the battle again and faced a powerful enemy, this ability to change spells would reappear.

Unable to learn more from Rowling, Rhodes had no choice but to give up his research on the situation.

In Rod's opinion, in this battle, Rowling may have relied on this special ability to exceed Rod's expectations of her, and did many things that Rod's could not achieve, but this ability is not stable.

Before Rowling fully understands this ability and controls it stably, even if Rod understands that Rowling's ability is extremely powerful, Rod does not plan to put all his hopes on Rowling's ability as he did in the face of meteor rain before.

After all, in the face of the meteor shower before, the fear of facing death directly, Rod didn't plan to experience it again, once Rowling couldn't exert this ability at a critical moment, Rod didn't think he would have a good end.

With the high-speed flight of the ghost dragon, Rhodes and his party at this time had already returned to the territory of Werning.

As soon as he came to the territory of Verning, Rhodes, who was on the body of the ghost dragon, felt the presence of the centaur leader and other undead creatures through the spiritual imprint.

The effect of the spirit mark has a certain range limit, when the distance between the necromancer and the undead creature exceeds a certain level, the spirit mark will be completely silent.

When the spirit mark is silent, the necromancer cannot give any instructions to the undead creature through the presence of the spirit mark, nor can he perceive the state of the undead creature. If the undead creature dies under the influence of an external force after the spirit sigil has fallen silent, the necromancer will not be prompted in any way.

Unless the necromancer keeps an eye on the spirit imprints at all times, and clearly understands the number of spirit imprints in his mind, it is difficult to judge the life and death of undead creatures far away from him.

The distance at which a necromancer perceives a spiritual imprint is generally related to the state of the undead creature itself, as well as the necromancer's own mental attributes.

Among these undead creatures, the Death Knight is the most special existence, because he has the identity of a hero, unless there is a great distance from the necromancer, the spiritual imprint of the Death Knight will never be silent.

The presence of the Death Knight gives the necromancer the opportunity to command the undead creatures from a distance. Relying on the control of the spiritual imprint, the necromancer's command of his army is far greater than that of ordinary generals.
