After pondering for a moment, Elinna replied, "My situation is indeed quite complex. According to the rules, I am indeed a Dark Elf now, but deep down, the blood of the Light Elf has always flowed within me. So, for me, I consider my soul to exist in the form of both elf traits. The same applies after being promoted to the Holy Spirit."

"Humph. Don't forget, Judge Yan allowed me to join the Nether Spirit Realm because he saw my talent in practicing both white and black magic. Therefore, my holy body retains the traits of both Light and Dark Elves, which also means that I retain the talent of practicing two types of magic that should inherently repel each other."

"So, these Elf Biscuits will still work for you, right?" Dao Lao asked cautiously.

"Of course, they will," Elinna answered without hesitation. "However, even if I can absorb the Dume energy contained in the Elf Biscuits with the Dark Elf traits and black magic power still present in my body, what does that accomplish? After becoming a Soul Guide, the power I obtained through studying upper realm spells is much stronger than the power obtained through this lower realm black magic. This kind of black magic is now merely meaningless low-level magic for me. I have no need to consume so many Elf Biscuits just to maintain the strength of this black magic."

"Besides, Dume energy cannot serve as a catalyst for practicing upper realm spells. So, for me, these Elf Biscuits are just delicious snacks," Elinna said, taking another piece of biscuit into her mouth.

Hao Yun and Dao Lao agreed with Elinna's explanation. However, they were also aware that the concealment technique Elinna used in the Green Passage was authentic Dark Elf black magic, and an enhanced version at that. So, while the Dume energy in the Elf Biscuits might not be helpful to her, it didn't mean that the black magic Elinna wielded was also devoid of value.

After a brief chat and rest, Elinna continued to narrate the history of the Dark Elf tribe.

Finally, the Dark Magic Association officially issued a new version of the "Dark Magic Teaching Outline" and made the information about Dume energy and Elf Biscuits public through its various branch associations.

Upon hearing this news, the entire Dark Elf tribe became excited. Dark Elves who had long been stuck in bottlenecks in their cultivation finally saw hope for breakthroughs and reignited their desire to practice black magic. At the same time, the doubts about the Dark Magic Association and Archbishop Anshilin in society vanished. Thousands of Dark Elves once again actively responded to the call of the Dark Magic Association, gathering in large numbers below Blackstone Castle to witness the power of black magic demonstrated by the elders of the Dark Magic Association after eating Elf Biscuits.

Many Elven individuals also received Elf Biscuits prepared in advance by the Dark Magic Association and, under the guidance of Elder Patrick, ate the Elf Biscuits on the spot while meditating to feel the changes brought by Dume energy. Thus, the entire Dark Elf tribe was completely captivated by the allure of Elf Biscuits. Every Elf hoped to obtain enough Dume energy to help them break through bottlenecks and continue to improve their proficiency in black magic.

Since they wanted to obtain more Dume energy, they needed to produce more Elf Biscuits. Therefore, the Dark Magic Association subsequently proposed the "Nationwide Advancement of Black Magic Plan." According to the requirements of the plan, to ensure that Dark Elves could continuously obtain Elf Biscuits, they needed the entire nation to participate in collecting raw materials for making Elf Biscuits and in the production process itself.

The Dark Magic Association mainly divided the work that Dark Elves needed to participate in into: first, to ensure smooth trade with Light Elves for Amadeus flowers and Egan herbs, while providing them with necessary technical support in construction and metal smelting, guaranteeing their demand for building stones and metal raw materials; second, to mine and refine Dume ore, as well as to be responsible for transporting Dume ore; third, to build large-scale factories for mass-producing Elf Biscuits in Dark Elf territory according to regional divisions; fourth, to establish specialized labor supervision departments in various regions and distribute Elf Biscuits based on the work performance of Dark Elves participating in the "Nationwide Advancement of Black Magic Plan."

The Dark Elves naturally gave unconditional support to the "Nationwide Advancement of Black Magic Plan" proposed by the Dark Magic Association. Thus, all Dark Elves once again devoted themselves to practicing black magic, dedicating all their time outside of practicing black magic to ensuring that they could obtain sufficient Dume energy through the "Nationwide Advancement of Black Magic Plan."

After the Dark Elf tribe once again vigorously engaged in the activity of practicing black magic, the Light Elves also joyfully discovered that the Dark Elves, who had previously caused trouble in the border areas, suddenly disappeared. They could finally return to the long-lost peaceful and harmonious life.

At the same time, the Light Elves sighed that the group of Dark Elves had spent so many years practicing black magic with such fanfare, but besides slightly strengthening their physique, firing some harmless black electric balls, becoming poorer and uglier, and becoming more irritable, it seemed like they hadn't achieved anything significant.

This made many Light Elves also start to believe that the previous concerns of the White Magic Association about practicing black magic making Dark Elves more dangerous were unnecessary. More Light Elves began to think that whatever Dume ore or invented biscuits discovered by the Dark Magic Association were probably just gimmicks created by the Dark Magic Association to alleviate social conflicts and consolidate their ruling position.

However, considering that the Dark Elves were continuously providing various stones and metals to the Light Elves in exchange for Amadeus flowers and Egan herbs, as well as related technologies, the Light Elves couldn't be bothered with the situation on the Dark Elves' side. In short, you pursue your elusive and impractical magic, while I pursue my readily available and comfortable life. Let's just live happily in our own ways!

Thus, the Light Elf tribe and the Dark Elf tribe peacefully passed nearly a hundred years, and the relationship between the two races eased once again due to regular trade.

During this blink of nearly a hundred years, the Dark Elves finally found a way to break through their bottleneck, elevating their overall proficiency in black magic to a higher level. Elf Biscuits, as a link providing connection between the Dark Elves and Dume energy, naturally played a crucial role in this process.

After breaking through the bottleneck, the Dark Elves did not want to merely pursue trivial matters in the practice of black magic. Under the leadership of the Dark Magic Association, they subdivided black magic into three different branches: the ability to enhance oneself through black magic, the ability to gather black magic energy bare-handedly like Archbishop Anshilin and launch remote attacks through magic spheres, and the ability to create curse spells using black magic power to connect with death and achieve resurrection.

Although the strength of the Dark Elves still couldn't fully unleash the power of these three types of black magic, compared to before breaking through the bottleneck, the spells they mastered now had some practical value. Seeing their further growth in black magic proficiency, the Dark Elves were naturally extremely satisfied. However, as they say, there's no such thing as a free lunch. Behind any achievement, there must be significant effort or sacrifice. For the Dark Elves, as they delved further into higher stages of black magic after breaking through the bottleneck, the negative effects they had to endure for practicing black magic began to quietly emerge.

Simply put, the negative effect of practicing black magic was a kind of backlash on the practitioner's mind. In fact, this kind of backlash had existed since the Dark Elves first encountered black magic. However, at that time, the black magic the Dark Elves could master was only relatively shallow, so the impact of this backlash was almost negligible.

But after the Dark Elves broke through the bottleneck in their cultivation, this mental backlash gradually became apparent. However, because this backlash gradually affected their minds as they progressed in their black magic growth, it was initially very difficult to detect. This also meant that the Dark Elves could not promptly identify this backlash and find effective solutions.

On the other hand, Elf Biscuits, which improved the Dark Elves' absorption and storage capacity of Dume energy, not only enhanced the efficacy of their black magic practice but also catalyzed and amplified the growth of the mental backlash. This made the Dark Elves highly reliant on these biscuits, which essentially became a disguised poison causing serious harm to their minds.

What made this poison more terrifying than ordinary drugs was that it indeed provided significant assistance in practicing black magic. Therefore, it's easy to imagine how difficult it would be for Dark Elves, who were extremely obsessed with black magic, to give up eating Elf Biscuits, even if it meant reducing the efficiency of their black magic practice or losing the opportunity to further enhance their black magic. After all, the temptation of Dume energy was too strong for them. With the blessing of Dume energy, the pleasure brought by the powerful magic of black magic was irresistible.

As the Dark Elves' proficiency in black magic continued to improve and they consumed more and more Elf Biscuits, the mental backlash against them gradually intensified. Especially for those Dark Elves with a weaker mental foundation, this backlash had an even more severe impact on them. Many Dark Elves began to experience occasional mental confusion or weakness. Sometimes, they would even experience auditory hallucinations or temporary amnesia.

However, regardless of the situation they encountered, they felt no panic or pain. On the contrary, they would feel a refreshing sense of pleasure in those pathological states. Because of this, the mindset of some Dark Elves began to change gradually. They started to slow down their pace of practicing black magic and instead spent more time eating Elf Biscuits, enjoying the pleasure of being filled with Dume energy.

As more and more ordinary Dark Elves experienced mental issues, the phenomenon of mental backlash was finally discovered by the Dark Magic Association. Aware of the seriousness of the problem, the Dark Magic Association naturally wouldn't sit idly by. However, apart from alleviating the symptoms on these Dark Elves by cutting off their supply of Elf Biscuits, the Dark Magic Association couldn't find any other reasonable solution for a while.

However, cutting off the supply of Elf Biscuits to these Dark Elves? This was also a very difficult task. It's not hard to imagine that for Dark Elves who were deeply obsessed and couldn't pull themselves out of it, taking away what they were addicted to would be even more unacceptable than taking away their lives.

So, as soon as the news of restricting the supply of Elf Biscuits came out, it would inevitably provoke strong negative questioning in society. Moreover, it might even cause turmoil within the Dark Elf tribe. Because at this time, another matter was causing a headache for the Dark Magic Association.

Although the Dark Elves had successfully broken through the cultivation bottleneck as a whole in less than a hundred years, what no one had expected was that the next cultivation bottleneck would appear even faster before them. This made the emotions of these Dark Elves, which had just returned to climax, abruptly stop, causing them great discomfort. As a result, doubts about the Dark Magic Association resurfaced in society. And this time, the Dark Magic Association seemed to have no effective solution at hand.
