Before entering the portal, Rhodes took advantage of the characteristics of the space-time gate to conduct a perception and explore how many areas above the main plane he could use the space-time gate to reach.

In previous lich gatherings, when Rhodes traveled to the various lich territories, he had left his own spiritual traces on the spatial calibration of their territories.

With the spatial calibration to confirm the direction, if Rod is willing, the gate of time and space he casts will naturally lead to the territory of these lichs, so as to quickly come to any location in Diya, which is also the invisible benefit that Rhodes obtained in the lich gathering.

At this time, Rhodes' perception of the number of places he was able to connect with the Space-Time Gate was greatly reduced, especially those territories that belonged to the Lich.

It seems that during this period of time, many lich demons have closed their spatial calibration, and the space-time gate cast by Rhodes cannot be connected to these locations, and only a few areas, such as the existence of the Death Desolation, are still open to Rhodes and can be quickly reached by using the space-time gate.

The caster can easily do this by using special means to deal with spatial calibration, such as turning off the positioning function of spatial calibration in wartime, or restricting it to a specific number of people, not to mention the presence of those lichs.

The lich is also guarding against each other, and no one wants to fight head-on, and the territory in the rear is sneak attacked, even if they can use the space-time gate to return quickly, they will suffer heavy losses, so the positioning function of the spatial calibration is turned off, and it is only open to some specific existences.

Because of this, the area that can be connected to the Gate of Time and Space that Rod has cast is greatly reduced, and it is impossible to travel through Diya as quickly as before.

This discovery also made Rhodes realize that the battlefield of Erathia, which belonged to the lich at this time, was likely to have happened unexpectedly, which had an impact on the lich, and Rhodes immediately stopped hesitating and entered the door of time and space.

When Rod's form disappeared into this space, the undead creature dived underwater and no longer showed its head, and the tentacles belonging to the Nether Kraken retracted into the whirlpool, waiting for Rhodes to descend on that special plane again.

Unlike the extremely chaotic inside the whirlpool, which can cut off the spatial turbulence of everything, the space inside the space-time gate is extremely stable, and Rhodes, who has passed through the whirlpool many times, can perceive this difference at once.

Smoothly passing through the gate of time and space, Rhodes walked out of a large teleportation monument, stepping on the solid stone platform under his feet.

Stepping on the solid land again, Rhodes couldn't help but feel a burst of emotion in his heart, recalling everything he had experienced in the water elemental plane before, even Rhodes didn't want to be exiled by spells again.

For Rod, the water element plane is still a mild area, with endless sea creatures in it, which can be used by Rhodes to transform undead creatures, in addition, the whirlpools in the ocean have the ability to cross space, if they are replaced by other planes, I don't know what year and month it will take for Rhodes to return.

The method of exile that the legendary mage used in the face of an invincible enemy was the existence that Rhodes had to guard against in the subsequent battles, and if Rhodes were replaced by someone else, they would most likely have been lost in the unknown space.

At this time, the gate of time and space behind Rod slowly dissipated, and Rod also saw all the scenery around him.

Rhodes found that the scene around the teleportation monument was very different from the city of Ao in his impression, surrounded by tall and gloomy buildings, the sky was shrouded in a dark canopy that obscured the light, undead creatures could be seen everywhere around, and figures in black robes continued to wander, and finally disappeared into the shadows completely.

Not far away, there is a pitch-black tower, rich in death energy, gathered by the tower, and under the guidance of the tower, it constantly surrounds the city of Saw, providing a more suitable environment for the undead creatures in the city.

The Soul Tower, which symbolizes the top city of the undead, also appeared in the interior of Ao City, and Rod felt a sense of abnormality in his heart.

Among the undead creatures existing in the city, the largest number is naturally the undead creatures such as corpse witches, and there are even many terrifying knights among them.

Relying on the ability of the Ghost King's cloak, Rhodes was able to control the corpse witches that existed around him, and it was obvious that the transformation of these corpse witches was based on the Corpse Witch King left behind by Rhodes before he was banished.

Thinking back to the city of Saw, which had not yet been rebuilt before he was banished, compared to the huge city of the undead in front of him, it was hard for Rhodes to imagine what had happened here during the nearly a month he had been in the water elemental plane.

Due to the shortening of the distance, Rhodes regained his perception of everything in the past, including the spiritual imprints of many of his subordinates, as well as the perception of blood with Rowling.

Rhodes noticed that as the undead creature that occupied the most of his spiritual attributes, the ghost dragon at this time was staying on the top of the pitch-black tower in front of him, and Rowling also existed here.

For some reason, at this time, Rowling did not notice the restoration of blood perception, so she failed to detect Rod's arrival.

In Rod's perception, Rowling's state was extremely stable, and at this time, she seemed to be performing a meditative move, and her mind was highly concentrated, so she had no time to notice the abnormality of blood perception.

After discovering this, Rhodes did not use his blood perception to directly transmit information to Rowling, so as not to disturb Rowling at this time, but walked in the direction of the pitch-black tower.

The information from the bloodline perception made Rhodes realize that Rowling at this time seemed to have a big change from the last time she saw her before she was banished.

Rhodes believed that all the changes that had taken place in the city were inseparable from Rowling's existence, and that without her signals, ordinary necromancers would not be able to make such big changes to Ao City, let alone build a real Soul Tower.

Compared with the giant Soul Tower in the City of Death, the Spirit Tower in Ao City is much weaker in terms of scale and momentum, and its height is also incomparable, not even exceeding the range of the dark canopy, and can only be regarded as a common tower.

Even so, the death energy gathered by the tower was enough to completely envelop the entire city of Saw, enough to cause the dead creatures in it to transform into undead creatures on their own in a short period of time.

The Spiritualist Tower, which has a special significance, and the growing city of Saw, seem to explain to Rhodes that the situation in the main plane is not as urgent as he thought, even without his presence, everything is gradually developing.

It's just that at this time, Rhodes can't confirm this, and only after seeing Rowling can he confirm this information to her.
