Chapter 1667: Expansion Scheme: Plane Inheritance

Xia Duo could understand Saville's excitement to some extent; after all, seeing something with one's own eyes that previously only existed in theory, no amount of excitement would be excessive.

It was much like before Xia Duo transmigrated; if he had seen a controlled nuclear fusion device that could only be built after fifty years upon fifty years, his reaction probably wouldn't have been much better than Saville's.

Furthermore, although Saville knew of the existence of the 【Mythallar】 device from Iolum, he himself had not participated in the research and development of the device.

Neither in the early theoretical stages nor in the later experimental ones.

From Saville's perspective, this was indeed an amazing Psionic Creation, but to Xia Duo, who had personally participated in the R&D, although the 【Mythallar】 device was indeed an amazing Psionic Creation, his sensitivity to it had long since been worn away by countless contacts in the past.

Xia Duo waited quietly for Saville to regain his composure, not uttering a single word of urging during the interval; he was asking someone for a favor this time, so he naturally had plenty of patience.

After a long while, Saville rubbed his eyes, turned his head, and said to Xia Duo, "Prepare the materials; I will go ask the teacher for two semi-planes."

"Expanding space requires using semi-planes?"

Xia Duo was very surprised by this result; one had to know that although the information Saville left at the Tower of Time was not very complete, it did not mention semi-planes a single time.

Only the Arcane Garden was explicitly mentioned as being a semi-plane.

"Of course it requires using semi-planes! Otherwise, do you really think I have such great ability to expand a space by several hundred times just like that?"

Saville shook his head inwardly; he was equally surprised that Xia Duo could ask such a question, "Generally, expanding a space by a hundred times is already the limit, and even that requires a large number of maintenance facilities."

"Expanding by several hundred times like the Tower of Time is impossible without using semi-planes, or perhaps you want that kind of expansion within a hundred times?"

"No, I need something larger."

"A very wise choice. If you only do a non-semi-plane expansion scheme within a hundred times, then both the current material consumption and the future maintenance costs would be far higher than a semi-plane expansion scheme."

Saville seemed very satisfied with Xia Duo's choice, "Since that's the case, prepare the materials as soon as possible. Once I return from Seventon, we will begin the modification."

"The materials are all ready, but can semi-planes only be obtained by asking the teacher?"

Come to think of it, if only semi-plane expansion were used, Xia Duo could do it himself; he was just missing a few semi-planes. Although he knew how to create this thing now, it was still somewhat difficult to create a semi-plane that existed for a sufficiently long time.

Through many experiments, Xia Duo discovered that the duration of a semi-plane's existence was largely proportional to the complexity, or rather, the completeness, of the Plane Root.

The semi-planes he had experimented with in the past, although they seemed to have taken shape, all belonged to the premature or short-lived type, while the complexity of the Plane Root of the semi-planes created by Iolum was at least an order of magnitude higher than his!

The process of creating a plane is very complex, and it is difficult for a Spellcaster to fully control it; one can only make settings at the source—that is, the Plane Root—and let the elements evolve naturally.

Thus, the degree of completeness of the Plane Root, or the 【Creation Blueprint】, is crucial.

Xia Duo had been tied up by all sorts of things over the past year and had no time to study the Plane Domain, which he most wanted to study from his heart.

Now, perhaps the consequences had arrived; he couldn't even produce two slightly stable semi-planes!

Regarding Xia Duo's question, a trace of embarrassment appeared on Saville's face, "The teacher originally wanted to teach me how to create semi-planes, but this Spell is not used often, and the casting time is extremely long, so I gave up."

"What a waste!" Xia Duo shouted in his heart, "It would have been better to let me do it!"

However, he had a very deep understanding of the long casting time for creating semi-planes that Saville mentioned.

For just the most successful micro-demiplane he had created that survived for less than a day, if cast in the Main Plane, it would take at least six hours to complete.

And if cast in the Ether Plane, it would take at least three or four hours to complete.

Of course, if the most time-consuming element filling process were replaced by the Element Pool of a Mage Tower, perhaps the casting time could be reduced somewhat, but not by much.

In Xia Duo's view, creating a semi-plane is not only mental labor but also physical labor; if the Spellcaster's physical fitness were slightly poor, they might not be able to persist.

Considering that his main energy would return to the Plane Domain after the construction of the Floating City entered a stable state, Xia Duo wanted to ask Saville to help him request a "Creation Blueprint" from Iolum.

However, this thought flashed through his mind only once before he abandoned it. It wasn't that Xia Duo was self-righteous and unwilling to take things from Iolum's side.

Isn't it only natural for a student to learn from a teacher?

The real reason he abandoned this thought was mainly that this matter was neither big nor small; it wasn't big enough to be a life-or-death crisis, and it wasn't small like those tangible resources.

Knowledge is priceless and difficult to measure with money, let alone profound knowledge involving the essence of the world like creating semi-planes.

Having someone else pick it up, even another student, was somewhat inappropriate.

Thinking of this, Xia Duo told Saville that he would contact the teacher himself, and at that time, besides the semi-planes, he might need him to help bring some things back.

Saville had no objections to this, and after the two agreed, they soon left the Blue Crystal Plane.

……

Savile Town, the original site of the Tower of Time.

After Saville left, Xia Duo sent a Sending to Iolum to explain the situation, and naturally, he did not forget to ask about the Creation Blueprint. Afterward, without waiting for Iolum's reply, he seized the time to finish the work on the No. 1 Spire.

Near noon, Xia Duo successfully finished the work, and good news came from Seventon: first, Iolum agreed to let Saville bring back the Creation Blueprint, and then Saville sent a Sending saying he had already obtained the two semi-planes.

Everything was moving in a good direction, and Xia Duo felt happy in his heart.

Before long, Saville appeared next to the No. 1 Spire. Xia Duo, who was in the tower, immediately discovered the other's figure and hurriedly teleported out from inside the tower.

"I'll leave the rest to you!"

"Rest assured, I won't let you down!"

As he spoke, Saville took out the Creation Blueprint that Xia Duo had been eagerly awaiting. It was not the Spell Scroll that Xia Duo had initially imagined, but a real Magic Book, or rather—a book-type Magic Item!

The moment he saw this book, Xia Duo realized that Iolum might have given him the inheritance. He solemnly took the thick Magic Book, which was shining with intense spiritual light, from Saville's hand.

Opening one of the pages, a phantom emerged from the page, changing its form. Seeing this scene, Xia Duo was even more certain of his guess.

Because this phantom alone was already demonstrating the Plane Root shaping process of a certain plane!
