Terrell looked at him and spoke with a solemn tone.

"You... you really have a way to restore it to its original state?"

"Of course, there is," Luo Yan said with a nonchalant expression, seriously pondering as he spoke, "It's just that I'm thinking... if there might be a more energy-efficient alternative that could replace the original system."

Terrell was slightly stunned, asking with perplexity.

"Energy-efficient?"

"Yes," Luo Yan nodded and continued, "Put simply, it means using less energy to maintain the lighting of the fourth layer of the labyrinth."

The entire labyrinth's energy structure could be said to be extremely unreasonable.

Perhaps it was due to the lack of quantitative statistical methods, or maybe it was due to a lack of management experience, but anyway, the previous Demon King's squandering of faith power could be described as extravagantly jaw-dropping.

After studying the design of the first four layers of the labyrinth, Luo Yan had gradually uncovered the root of the problem.

The entire labyrinth was facing a tremendous deficit of faith value.

There were many reasons for this.

Perhaps there was a period when the surface humans had relaxed their faith, selling their souls to demons, causing a sudden spike in faith power balance in the labyrinth, and so the Demon King began to build extravagantly.

And just as the new facilities were completed, the surface humans reinforced their faith in Saint Sis, causing a sudden drop in the increase of faith power in the labyrinth, with expenditures surpassing income, and consequently, the labyrinth couldn't be maintained.

From this perspective, Reggie Dragon's bold invasion of the surface world couldn't completely be seen as an irrational move, at most it could be considered a reluctant choice.

After all, the grand spectacle was simply unsustainable based solely on the faith power contributed by the local monsters; it had to rely on the input of external faith power.

This was like a typical export-driven economy; when the "external market" contracted, there were ultimately only two outcomes—either quietly fade into decline, or have a resounding clash with those on the outside.

Reggie Dragon was, after all, a Demon King, and moreover, from a well-known family in Hell. Even if just for face, he had to choose the latter and take a gamble.

Even if he couldn't enlarge the surface humans' fear of the Hell forces, he could at least consume the surplus monsters, and dying in battle sounded better than starvation.

Only, Reggie Dragon might not have expected that his opponent was also ruthless, willing to sacrifice his lifespan to stab him, leading to the complete collapse of the Demon Army.

Thus, the present situation had been created.

Both the surface and the underworld saw a vacuum of order, therefore giving Chaos a chance to invade.

Luo Yan did not plan to follow in Reggie Dragon's old footsteps.

Especially since he had a multitude of players to support, every expenditure of faith power had to be carefully calculated.

With that in mind, he pondered and said.

"...If there were some way to convert sunlight into magic power and then transmit it underground through Netherworld Language, that would be ideal."

It was said that the Dwarves possessed similar technology.

And it wasn't just the Dwarves, even the Demon City of Hell had it.

For instance, the Purple Crystal Dome stolen from the Dwarves utilized a kind of fungus that grew on obsidian to convert geothermal energy into magic power for maintenance.

The Demons of Demon City were very aware that although faith power could create miracles, not all problems could be left to miracles to solve.

Terrell, astonished, looked at the Lord Demon King, incredulously saying.

"Is such a thing... possible?"

"It's worth a try. If it really doesn't work, then I will use faith power to solve it,"

While saying this, Luo Yan paused for a moment, then continued.

"To complete this project, I would like to borrow an expert in the field of botany... preferably a Mage well-versed in knowledge of monsters and proficient in natural magic spells."

"Regarding this matter, I believe Helen is the most suitable choice," Terrell looked to his eldest daughter and then turned to Luo Yan, saying, "Her research into nature-based spells even surpasses mine. You may ask her about any issues you have in the field of plants."

Helen nodded slightly, respectfully stating,

"Helen is pleased to be of service to you."

Sherry pouted somewhat unhappily, seeming not quite convinced by her father's statement, but ultimately she said nothing.

Luo Yan's face revealed an approving smile as he nodded at the father and daughter.

"Excellent! With your help, I believe my chances will be even greater."

As he spoke, he cast his gaze towards the crystals tenaciously growing atop the dome.

By now, an immature plan had formed in his mind.

If he could imitate Demon City and create a type of plant-based magical creature, one that could draw magical power from nature and store it into these crystals, it might not only solve the lighting needs of Mist Forest but might also provide a vast surplus of magical power for the first three levels of the labyrinth!

As for how to realize this plan, Luo Yan intended to impart some biological concepts from Earth to Helen.

After all, magic is a manifestation of cognition.

If she could gain a deeper understanding of nature's secrets, comprehend "photosynthesis" and such complex concepts, it might produce unexpected effects.

Hadn't a certain Mechanical God once done something similar?

Applying the ideas of the programming realm to inscriptions...

While Luo Yan continued refining the idea in his mind, Youyou's voice suddenly reached his ears.

"Lord Demon King, your Iron Teeth City is under attack by a group of clay golems!"

Luo Yan immediately snapped back to reality, inquiring with his thoughts.

"How many are there? Is it serious?"

Youyou: "There are about fifty or more! This is undoubtedly an organized invasion... Ah, but it seems like it's not a big issue? Your players called for a ghost that can cast spells, and with a wave of its hand, it 'guangguang guang' blasted those clay golems flying! However, it's strange, the spells it uses look somewhat like mechanical magic? But not entirely?"

Mechanical magic?

Luo Yan's face showed a perplexed expression.

He could guess the identity of that ghost; if he wasn't mistaken, it should be that cowardly Miranda.

Since the end of the war, he had vanished without a trace, and it was unexpected that he would appear in Iron Teeth City.

Within moments, Youyou's voice came through once more.

"It's resolved! Those clay golems are retreating... Yikes! They truly must be organized, right?!"

Golems without consciousness do not retreat!

"It looks like the ruler of the third level is causing trouble," Luo Yan narrowed his eyes and slowly said, "It seems they have become tired of living."

The inspection of the Dome Crystal was complete.

The inscrutable Lord Demon King already had an idea in mind.

Looking at his confident demeanor, the Dark Night Elves of the Gray Wind Tribe began to harbor more hope for the future.

Luo Yan bid farewell to Terrell and the other high-ranking members of the Gray Wind Tribe, while Helen and Sherry remained as his bodyguards.

Just as he was about to head to Iron Teeth City to inspect the situation there, an unexpected message abruptly altered his plans.

A reply from Hell—

It had finally arrived!
