Chapter 742: Open Source, Reduce Expenditure, and Trace Back Memories

However, at the moment, Xia Duo has no way to obtain a Mythallar, and he doesn't even know if Iolum has actually invented the Mythallar yet.

To solve the energy crisis, it generally boils down to increasing revenue and reducing expenditure.

Increasing revenue via a Mythallar is temporarily impossible, but it is not as if there are no other methods; Xia Duo remembers that among the books he copied back from the 【Projection Plane: Arcane Empire】, there are improvement plans for spell laboratories.

It is just that in the past, the Tower of Time never had the trouble of excessive energy consumption in its spell laboratories, and since the Tower of Time's spell laboratories were already formed and difficult to modify, he hadn't spent much thought on this.

He had originally intended to use this plan for his own future Mage Tower, but now it seems he might need to study it in advance.

As for reducing expenditure, it is even simpler; it is nothing more than restricting the apprentices' use of the spell laboratories, which is the fastest method to see results in the short term.

After thinking for a moment, Xia Duo told Niya about these two plans for increasing revenue and reducing expenditure he had just thought of, and at the same time asked: "There are quite a few people at Giles Tower; how do they manage to keep going over there?"

"The number of people at Giles Tower hasn't been higher than ours for a long time!" Speaking of this, Niya couldn't help but roll her eyes at Xia Duo, then continued:

"Their approach is similar to what the Tower of Time did before; using the Spell Practice Rooms requires paying on time and in full, so as to control usage time.

"In addition, although Giles Tower was built earlier, it has undergone many modifications since, and the capacity of its Element Pool is at least a dozen times that of the Tower of Time! But even so, Giles Tower still consumes Arcane Crystals as a supplement from time to time."

"Huh—"

Hearing Niya mention that Giles Tower modified its Element Pool, Xia Duo's heart suddenly stirred, "Can the Tower of Time's Element Pool also be modified?"

If there could be one more way to increase revenue, it would undoubtedly be safer.

But Niya shook her head at this, "It's too difficult. If it were an ordinary Mage Tower, modification wouldn't be difficult, but the Tower of Time is a Mage Tower built by Great-grandfather Saville; key core facilities like the Element Pool definitely have Multi-level Backup Arrays!

"The difficulty of wanting to modify it is extremely high. At the very least, it would require a Great Arcanist to formulate a perfect modification plan. Furthermore, the volume of the modification project is also very large; with the Tower of Time's current capabilities, it cannot complete such a modification."

"……"

Only then did Xia Duo remember that the Tower of Time possesses Multi-level Backup Arrays.

These backup plans allow the Tower of Time to switch back and forth between the 1st Circle Expression and the 11th Circle Expression, and it can always maintain the highest power equivalent to the 11th Circle to cope with different Magic Net environments outside,

It is just that the normal 11th Circle Expression is more efficient!

It can be said that more than half of the Tower of Time's costs are spent on these backup plans, especially the 1st Circle Expression, which enables the Magic Array construction at the 1st Circle level to have the effect equivalent to the 11th Circle. Even if some components can be shared, the amount of redundancy is still extremely vast.

No wonder a major overhaul before cost over a million Gold Coins.

Such a large amount of Gold Coins is already enough to build a relatively decent ordinary Mage Tower!

Thinking of this, Xia Duo couldn't help but feel a bit desperate; he feared that before becoming a Great Arcanist, it would be impossible for him to build a Mage Tower like the Tower of Time.

At the same time, he thought of another question and hurriedly asked Niya: "The spell laboratories shouldn't have adopted the Multi-level Backup Array plan, right?"

"How is that possible?" Niya widened her eyes and said in surprise:

"Of course not. Otherwise, when you proposed improving the spell laboratories just now, I would have said so. Only the core facilities of the Tower of Time have Multi-level Backup Arrays. If everything had them, how much would that cost? The Tower of Time could never have been built!"

Xia Duo carefully recalled the Tower of Time's Magic Array design blueprints he had once seen in the core Blueprint Room of the Tower of Time. Some time had passed, but to his surprise, he actually recalled that design blueprint in its entirety.

"How is this possible?!" Xia Duo felt a bit incredulous.

But that three-dimensional pattern, composed of countless complex yet not messy, but rather orderly and beautiful lines, was displayed clearly and plainly in his mind, forcing him to believe it!

Unlike the blueprint in the real scene, this blueprint could not be partially zoomed in to show more details the moment he stared at it.

Only what he had seen could be recalled; it could not be fabricated out of thin air.

However, after recalling for a long time, he still didn't understand where the Multi-level Backup Array was. The only thing he knew was roughly what Niya had told him before—"blue lines are normal, red are abnormal"—and his own deduction that "the denser the lines, the more complex the function."

The anomaly in his memory left Xia Duo with no more heart to stay with Niya. He couldn't wait to go back and study it. If he hadn't guessed wrong, this likely still had to do with his brand-new Soul State!

Could it be that the Bloodline Awakening last time—the cloud-riding, the Dragon's Majesty, the Dragon's Magic Resistance—were all secondary? Was the anomaly in his Soul the primary thing?

Thinking of this, Xia Duo could no longer stay. With his memory flashing again, he accurately retrieved the notebook containing the spell laboratory modification plan from his Personal Space and handed it to Niya:

"This notebook contains some data I recorded from the Projection Plane, including the modification plan for the spell laboratories. You take a look at it first, and we'll discuss it in a couple of days."

"Okay."

Seeing this, Xia Duo was about to leave immediately, but Niya mentioned one more thing: "Uncle Sain sent 100 people over yesterday, saying they were the Tower of Time servants you wanted?"

Xia Duo's footsteps paused. He didn't expect Town Mayor Sain to have sent the people over yesterday; he really was efficient enough!

"Yes, some servants were converted into apprentices before. The people who came this time are full-time servants, and we might recruit more later based on the actual situation."

"I understand."

"Then I'll be going first."

"Mm."

……

After leaving Niya's residence, Xia Duo immediately signaled the Tower Spirit to teleport. Once he returned to his own residence, he began to take out the notebooks from his Personal Space one by one like a little squirrel storing food, lining them up neatly on his desk.

While taking them out, he kept recalling the contents of the notebooks until the desk was completely piled up, and only then did he stop.

"Sigh! It's a pity it's not a perfect photographic memory!"

Xia Duo was sighing outwardly, but in reality, his heart was already blooming with joy.

The newly discovered ability was quite useful; the vast majority of the content in the notebooks was recalled by him, with only a small portion still remaining somewhat blurry.

The only regret was that this new ability was only effective for memories after Xia Duo transmigrated, and ineffective for memories from before the transmigration.

It was as if the moment he transmigrated, his memories became a painting; what should be clear was clear, what should be blurry remained blurry, and what should have disappeared could not be thought of no matter what.

Of course, there were benefits; at least the clear memories he already had from before the transmigration would no longer become blurry, and he even recalled many memories from before the transmigration that had disappeared with the passage of time after he arrived.

If one were to be optimistic, with the current development of his soul, it might not be impossible for him to trace back all his memories from birth to the moment of transmigration in the future.
