In Rod's opinion, although there are a large number of undead creatures at the top of the tower, they are still limited in their role in the face of Eric.

Once the real battle begins, if there is no special means, these undead creatures on the top of the tower will probably be wiped out by Eric in an instant.

According to Rod's understanding of legendary mages, with the addition of various professional specialties, the damage that the spells cast by legendary mages will surpass all conventional things, which is extremely obvious in some large-scale high-level spells.

In Rhodes's impression, when the mage's rank reaches the seventh order and becomes a real legendary mage, he can make certain changes to the spells with fixed effects according to his own needs, so that the effect of the spells meets the current needs.

Regarding such a special ability, Rod once had a very deep feeling in Rowling's body, and in the game of his previous life, Rod also had a complete understanding of it.

Rhodes believed that Eric, who was in mid-air, apparently had this ability, which changed the effect of spells and was no longer limited to the basic abilities of spells.

In Rod's impression, even in the entire Bracada, there may not be many mages who can outperform Eric in terms of spell casting ability, and only a very small number of mages who exist in the magic guild can do this.

For this reason, in Rhodes's opinion, these undead creatures gathered on the top of the tower, if they have no protection, only need Eric to release an undead killer, and even other high-level spells can be cleaned up, and by the way, even the death energy can be completely purified.

In the hands of powerful mages, common spells in the past can often show unusual abilities, and the gap in rank is destined to appear.

In the process of moving forward, Rod's eyes were also on Sandru, who still wanted to see him at this time.

Looking at Sandru who was getting closer and closer, Rhodes understood that he could perceive the threat of the undead killer to the undead creatures, and there was no reason why Sandru could not perceive it.

In this case, Sandru still dared to let these undead creatures gather at the top of the tower, obviously having the means to not be afraid of Eric.

In Rhodes's perception, as he moved forward, the death energy around the top of the tower became more and more intense, and this change did not stop.

Prior to this, when Rhodes sensed the abnormal changes in death energy, he thought it was caused by a large number of undead creatures, or perhaps it was related to the power of the artifact in Sandru's hand.

But at this time, through the various anomalies found in his perception, Rhodes was able to confirm that the existence of death energy may not have much to do with the things he originally expected.

From the large amount of death energy that appeared around him, Rhodes noticed that the source of this death energy was not the undead creatures who came here, but the spirit tower where he was located.

Through the detailed perception of death energy, Rhodes found that the first place where these death energy came out was the surface of the Soul Tower, the spell rituals one after another.

Due to being at the top of the tower, in the process of moving forward, Rod could not directly see the ritual lines on the wall of the tower as before, but through his own perception, Rod was also able to imagine the scene over there.

At this moment, as if it had been guided by something, the many death energies around it condensed around the Soul Tower.

Rod noticed that there were no ritual patterns on the surface of the top floor of the tower, and the last ritual pattern that Rod saw was on the wall of the tower when he came to the top floor through the stairs.

But at this moment, relying on his own perception, Rhodes was able to perceive the traces of the operation of the spell ritual from the surface of the top layer.

It was also the appearance of all these circumstances that allowed Rhodes to confirm that the death energy that existed around the top of the tower at this time was gathered through a spell ritual.

In Rod's perception, these death energies that had been gathered began to undergo special changes under the effect of spell rituals.

The surrounding death energy no longer exists in the form of a pure magic element, but gradually has an entity, under the gathering of a large amount of death energy, the periphery of the Soul Tower, especially the top area, is covered by a layer of huge translucent black veil, and Rhodes, who is at the top of the tower, can clearly perceive this.

The changes that appeared in front of him had naturally attracted Rod's attention, and Rod believed that Eric, who was in mid-air, naturally understood what these death energies meant.

What made Rhodes concerned was that even after noticing the changes below, Eric didn't seem to have any intention of stopping what was happening, but let Sandru make all kinds of pre-war preparations.

Rod noticed that when these kinds of changes occurred, Eric looked at Sandru again, and there were some inexplicable emotions in his eyes, and his expression was no longer as calm as before.

The discovery of this situation gave Rod some new views on Eric. Rod realizes that Eric clearly doesn't just think of the former Sandru as an ordinary student.

Recalling the scene when he saw Eric in the Potions Competition, Rhodes recalled that at the academy event where many high-level mages gathered at that time, Eric was still wearing a gray robe without any decoration.

In Rod's impression, including in his previous life, when he saw Eric, he was wearing that style of robe.

But at this time, in the process of coming to Diya to meet Sandru, Eric changed his past and chose to dress in a very formal and most important way to show his identity, which is enough to show his recognition of Sandru.

Rhodes believes that it is this recognition that makes Eric allow this to happen even though he is aware of Sandru's pre-battle preparations, and does not immediately strike and cast the most powerful spell when he first meets Sandru.

After realizing Eric's behavior, Rhodes looked at Eric again, and there was something different.

Recalling that in Bracada, Eric has a very high evaluation among many mages, even legendary mages will recognize this in their hearts, and Rhodes understands why.

As Rhodes observed Eric, above his head, a translucent black barrier made of death energy had been fully formed.

The existence of the barrier separates Eric, who is in mid-air, from all the undead creatures at the top of the tower, but it does not block the view.

At this time, Rod had also come to Sandru's not far away.
