In the vast Void Zone, it seemed that there was no end to it.

"Whoosh."

A huge flying ship gradually appeared in the Void Zone.

"According to the dimension map, there's a dimension not far away."

Merlin carefully looked at the dimension map in the flying ship.

He left the Shkedu Dimension, and had flown for several years but he was still drifting in the Void Zone, which showed how vast the Void Zone was. Moreover, all the places he had passed were within the sphere of influence of the Spell Caster civilization. He had not set foot in any foreign civilizations or vast open areas.

Even so, he had flown for several years, and still had not reached the Saitu Dimension.

"The dimension in front is an open dimension. I can go there and rest."

Merlin understood from the dimension map that the next dimension was an open dimension. That meant that the dimension's master did not reject other Spell Casters from entering, and even exchange some items in the dimension, much like the Shkedu Dimension.

There were some dimension masters who did not wish to be disturbed or because the living creatures in the dimension were not strong enough, so they did not open up the dimension. Others would not be able to enter the dimension without the master's permission. Otherwise, it would be regarded as a provocation to a Great Legend.

In general, Great Legends who had signed the Legends' Accord would not force themselves into a dimension that was not open.

In the Aurora Ship, Merlin soon saw an unusually beautiful dimension in front emitting multicolored lights.

This dimension was different from all the other dimensions Merlin had seen before. Not only was this dimension large but it also emitted a variety of lights like colored ribbons, enveloping the entire dimension.

However, upon closer look, he was shocked to find that it was a gigantic Runic Magic Circle that shrouded the entire dimension. Runology had grown by leaps and bounds after Spell Casters stepped into the Void Zone but it really was quite outrageous that it grew to the point of being able to shroud an entire dimension with a Runic Magic Circle.

Even the Great Wizard Fidel, who had very high attainments in Runology, did not have such an ability. However, if the Great Wizard Fidel could become a Great Legend after entering the Void Zone, perhaps his attainments in runology would be even higher.

Merlin urged the Aurora Ship toward the dimension, and the Runic Heartprint between his eyebrows also flickered, wanting to thoroughly understand this gigantic Runic Magic Circle.

However, as Merlin expected, even the Runic Heartprint was unable to see through this Runic Magic Circle.

"Whoosh."

Merlin slowly flew into the dimension. This dimension had a pleasant and appropriate name called that Rainbow Dimension, meaning that it was like a rainbow.

Merlin urged the Aurora Ship, and had just flown into the Rainbow Dimension when three Great Wizards immediately appeared before him. Merlin's heart jolted, and he immediately put on his guard, ready to cast Darkness Eye at a moment's notice.

These recent years, Merlin encountered a few dimensions where he was immediately attacked after entering the dimension. Merlin later learned that some Spell Casters had prepared to ambush when unfamiliar Spell Casters appeared, where they would initiate a flood of attacks.

Spell Casters like these were not much different from plunderers. However, they did not have the ability of plunderers, and could not plunder the dimension's Elemental Origin, so they specialized in plundering other Spell Casters instead!

Merlin had experienced this several times but he killed them instead. Therefore, seeing this situation now, he immediately became alarmed.

"Please calm down. In the Rainbow Dimension, no one dares to do anything so brazenly!"

One of the Great Wizards hurriedly waved his hand.

"Oh? Then what are you doing?"

Merlin did not ease his vigilance. His eyes constantly scanned the three Great Wizards.

"I believe you don't know about the Rainbow Dimension. The Rainbow Dimension is the last dimension in the dimension map that the Spell Caster civilization can influence. After leaving the Rainbow Dimension, you'll enter a much bigger Void Zone. There, you'll encounter foreign civilizations or maybe even discover new barren dimensions or encounter various types of wondrous things. In short, this place is a paradise for adventurers. As long as you have ambition and courage, you can choose to enter it to experience it yourself!"

Merlin nodded thoughtfully. It was not like he was completely clueless about the Rainbow Dimension. He knew that the Rainbow Dimension was seemingly the last dimension marked by the Spell Caster civilization on the dimension map.

Of course, that did not mean that the Spell Caster civilization only had the Rainbow Dimension. Perhaps in the open territory, there were also many Spell Casters who had controlled several dimensions. However, due to some special reasons such as competition between foreign civilizations, these dimensions would be full of uncertainty. It was a more chaotic and dangerous area.

Therefore, in such a situation, no one could count just how many foreign civilizations were there. The Spell Caster civilization was just one of those many civilizations. Although not many civilizations had a clear-cut stand during confrontations, there were endless fights and battles over dimensions.

Merlin knew that he might face some troubles after determining the coordinates of the Saitu Dimension. That was because the Saitu Dimension was located in the open territory, and was not protected by the Spell Caster civilization.

In other words, if there were foreign plunderers in the open territory, the Spell Caster civilization would not bother them as it would be too easy to cause fierce confrontations between civilizations. It would do more harm than good.

"Back then, it was Wizard Saitu who had plundered a barren dimension here by chance! It's just that after so many years, it's hard to say whether Wizard Saitu is still in the dangerous open territory."

Merlin's heart sank slightly. He had to be careful in such a dangerous place.

Hearing the explanation from the three Great Wizards in front of him, Merlin nodded. "In other words, the three of you are trying to make me join you on the foray?"

"Join us? That's not wrong. We already have three Great Wizards. If you're interested, we can immediately sign an agreement. Even if we find a barren dimension, we can take turns to comprehend the Elemental Origin, and split the resources and treasures found in it equally!"

The most fundamental reason these Great Wizards took risks was because of Elemental Origins. Of course, they did not have the power to directly plunder Elemental Origins and form Maxims. However, if they could comprehend the Elemental Origin, condensing Maxims would become much easier.

If one could obtain a dimension for a thousand years, then a peak Great Wizard's chances of forming a Maxim would increase by at least twenty percent!

Although it was only twenty percent, it was already quite terrifying. If a peak Great Wizard wanted to form a Maxim, it would already be considered good if their success rate was ten percent. Most did not even have a ten percent chance. By controlling a dimension, they could increase the success rate to twenty percent. It was not surprising that those these Great Wizards were so crazy.

"Those aren't bad conditions. However, I'm not a Great Wizard!"

Merlin kept the Aurora Ship, and emitted the life force on his body. His Seventh-level Spell Caster life force was very obvious, and the three Great Wizards' expressions instantly darkened slightly.

"Sigh, what a shame. With such a good casting tool, we thought that it would belong to a powerful Great Wizard. Who would have thought…"

The three Great Wizards shook their heads and left. They would not waste their time on a Seventh-level Spell Caster who was of no use to them.

In the open territory, there were many powerful foreign tribes. Even Great Wizards had to gather a few dozen before entering, much less a Seventh-level Spell Caster.

"They're so practical."

Merlin looked at the three Great Wizards in ridicule, and shook his head. If one was not a Great Wizard, it was indeed easy to be "ignored" in a place like this.

Merlin then continued downward, and soon found a place to land. He spent some elemental crystal stones to live in a quiet room.

Then, Merlin began to freely wander the streets that were full of powerful Great Wizards. There were very few Ninth-level Spell Casters, so Seventh-level Spell Casters like himself really "stood out".

Besides Spell Casters, Merlin also saw a few strange foreign tribes. They even openly walked in a Spell Caster civilization's dimension.

Upon closer understanding, Merlin found out that these foreign tribes were foreign civilizations that had better relations with the Spell Caster civilization. After all, in the Void Zone, there were many foreign civilizations. There were enemies such as the Rock Tribe that were hostile to the Spell Caster civilization.

However, some foreign civilizations were friendly or neutral, where they did not have any concerns. For example, the Giant civilization was too far away from the Spell Caster civilization but both sides were relatively friendly.

The Rainbow Dimension was on the edge of chaotic open territory, so there would naturally be many foreign tribes. Perhaps it would be difficult to encounter a foreign tribe in other places, but it was quite a common sight here.

"Looks like it's quite dangerous to enter the open territory to find the Saitu Dimension. I need to make sufficient preparations. First, I'll need a more detailed dimension map for the open territory!"

Merlin knew that dimension maps were very important. They could help one avoid dangerous areas such as places occupied by powerful foreign tribes. If they approached accidentally, those foreign tribes would not ask for a reason and directly act.

Therefore, a detailed dimension map was extremely important!

Merlin strolled for a long while before finally arriving at a store that was more luxurious and decorated. In it was all sorts of things that Merlin did not recognize, and most were items from foreign tribes. After these foreign tribes were killed, Spell Casters would drag their corpses to the Rainbow Dimension and start selling them openly.

"Do you have a dimension map here?"

Merlin looked at the dazzling items but none of them caught his interest, so he asked directly.

"Honored Wizard, you need a dimension map for the open territory?"

A gray-robed Wizard asked respectfully.

"Yes, after coming here, I naturally need to buy a dimension map for the open territory."

Merlin had a dimension map, but there were very few maps of the open territory. Furthermore, the prices were quite costly, and could only be bought in the Rainbow Dimension since they were generally not circulated.

Several Spell Casters even especially entered the open territory in order to draw precise dimension maps, and then earn large amounts of elemental crystal stones from them.

The gray-robed Wizard looked at Merlin and smiled. "We have an extremely accurate dimension map. It was planned by ten Great Wizards three days ago, but only seven had returned. It's definitely the most accurate dimension map."

The gray-robed Wizard did his best to praise the dimension map, and Merlin said impatiently, "You don't have to explain so much. How many elemental crystal stones does it cost?"

"If you really need it, then the most detailed dimension map only costs five hundred thousand elemental crystal stones!"

The gray-robed Wizard pondered before reporting an amount.

"What? Five hundred thousand elemental crystal stones?"

A sharp light flashed in Merlin's eyes. He almost thought this gray-robed Wizard was committing daylight robbery. In general, dimension maps cost a few tens of thousands of elemental crystal stones at most, but this person wanted five hundred thousand elemental crystal stones. Even if Merlin had a lot of elemental crystal stones, he did not want to be regarded as an idiot.

"Honored Wizard, this is the newest dimension map that three Great Wizards sacrificed their lives for. This is already a low price. Of course, if you don't want to use the newest map, we have other maps drawn a while ago. They might not be very detailed, but they're also quite good. One costs only a hundred thousand elemental crystal stones!"

"There are even cheaper alternatives if you want them which costs only twenty thousand elemental crystal stones but they were drawn one hundred years ago.

After the gray-robed Wizard had finished speaking, he quietly waited for Merlin's decision.

Merlin gritted his teeth. A dimension map had to be the most detailed, otherwise, there was no use for it as one could even be misled! Furthermore, he wanted to enter the open territory to find the Saitu Dimension, so he naturally needed the most detailed map to find a safer route. Otherwise, it was extremely dangerous to enter in a muddle-headed way.

"I'll buy it. Give me the latest and most detailed map!"

Merlin said lowly, and took out five hundred thousand elemental crystal stones. Very quickly, the gray-robed Wizard carefully took out a perfectly mounted dimension map.

Merlin gave it a cursory glance and saw that it was indeed very detailed. However, he still had to take it back to study it. Three Great Wizards had lost their lives just to draw this map. Merlin had to be extremely careful, and be fully prepared if he wanted to enter the open territory to find the Saitu Dimension.

Seeing Merlin's departing back, the smile on the gray-robed Wizard's face gradually fell. He shook his head helplessly and sighed. "Another one who bought the latest map and preparing to enter the open territory. The open territory isn't peaceful recently. I heard that another Wizard discovered a barren dimension. Tsk tsk, there's only a slim chance of survival if he goes in now."

The gray-robed Wizard simply sighed. After so many years in the Rainbow Dimension, he had lost count of the number of brilliant and ambitious Spell Casters who entered the open territory, and never came back...
