In the laboratory, Yuri had completely fainted from the ghostly hand's earlier rampage.

Locke knew that information about the Abyss demon race was still relatively scarce in the southeastern quadrant wizard world.

Most planes, the moment they came into contact with the wizard world, would be targeted by various wizards.

First Circle wizards were only basic combat power in the wizard world, but in other worlds, they were already legendary existences at the demigod level.

In other words, First Circle wizards could already go to worlds of medium scale or below to wage war. But the Abyss planes were one of the rare worlds that wizards hadn't conquered, and even fought back and forth with the wizard world.

In the southeastern quadrant, Abyss studies were even a relatively blue ocean discipline, with not many people researching it.

At this moment, under Locke's interrogation, the ghostly hand had no choice but to reveal its origins.

"Lord, sir, you are an Abyss Lord. As a lower-level demon, I can only follow your instructions." The ghostly hand said helplessly, "I am a Mammon demon, living on the seventh layer of the Abyss plane, the Sea of Acid. Ruling there is the Abyss Prince [Glyfferous], the Seven-Mouthed Duke. Legend has it that with one mouth, He can devour a medium-scale plane, and when He opens all seven mouths simultaneously, He can devour a large world. I was hunted by other demons in the Sea of Acid and was left with only the last bit of remaining limbs. For us demons, limbs are energy, and energy is our life."

"Demons devour each other in hopes of breaking through racial limits and breaking through to become higher-level demons. Mammon demons are lower-level demons with limited potential and limited ceiling. It's difficult to become an Abyss Lord, and we can only become cannon fodder in the eternal blood war."

"But if we can devour and mutate to become Abyss Flame Demons or Juggernaut Demons, those kinds of high-level demons, we can continue to grow stronger."

"Tanar'ri demons are the lowest-level lower demons, the untouchables of the Abyss. They can only be cannon fodder for life and never have hope of turning their lives around."

"Like your Beholder race, originally Beholders were just ordinary lower-level demons, but if they can devour each other and mutate into Beholder Lords, they can immediately advance to mid-level demons, become Abyss Lords, and gain the possibility of continuously strengthening themselves."

The ghostly hand seemed very envious and mistakenly believed that Locke was the mid-level demon it spoke of. "Beholder Lords are relatively rare even among the Beholder race. It's not that Beholder Lords are really that powerful, it's because once they mutate into Beholder Lords, their rank becomes mid-level demons, and they can continuously gain power and become higher-level existences."

"Among your race, there's even a Beholder Lord who, through continuous devouring, consecutively broke through racial limits, became an Abyss plane master, independently controlled an Abyss plane, and became an Abyss Prince, a favorite of the Abyss."

The ghostly hand said, "Just as I was about to be completely devoured, I was very lucky and happened to encounter a demon duke from our Abyss plane battling a Second Circle wizard from their wizard world." 𝗳𝐫𝚎𝗲𝚠𝚎𝗯𝕟𝐨𝘃𝚎𝗹.𝗰𝗼𝗺

"The war created a planar rift. I escaped along the planar rift all the way, finally becoming just a piece of flesh tissue the size of a finger, and then I was picked up by a human wizard."

"At that time, I originally wanted to kill him, but I was really too weak. I could only disguise myself as just a piece of mindless flesh. He didn't notice that hidden within the flesh he picked up was me."

"He used me to configure potions. As a result, through his potion, I parasitized inside that witch's body. Over twenty years, by borrowing her life force, I finally recovered a bit of strength and recovered to the extent of an arm."

"This is the special talent of us Mammon demons. We can restore our bodies by devouring others' life energy. Other demons don't have our powerful recovery ability."

Locke frowned and looked at the Mammon demon's arm in his hand. His sensation from touching it was clearly the tactile feeling of a flesh and blood body.

But if what it said was true, then this Mammon demon couldn't be an ordinary flesh and blood creature. On the contrary, the life form of Abyss-type creatures very likely differed from all organisms in the prime material plane.

That was worth studying carefully.

Locke currently took Abyss potion studies as his main research direction, so naturally he wouldn't pass up directly capturing a relatively high-level Abyss demon that could communicate and maintained its intelligence.

The other party being so forthcoming seemed to also be related to it mistaking him for a Beholder Lord.

Otherwise, the other party might not be willing to say so much.

Locke thought, "The quality of your energy roughly equals a wizard apprentice with 900 magical pressure. And Yuri's magical pressure isn't even 600. After so many years of you feeding on her, she's even regressed to the level of 200 magical pressure."

"Naturally, you'd recover very slowly feeding on her life force."

After hearing all this, Locke had two speculations—

First, Abyss creatures could restore their bodies by replenishing energy. It was just that different Abyss creatures had different degrees of this characteristic. The Mammon demon he captured possessed a special talent and was particularly outstanding in this aspect.

Therefore, from observing its experiences, he boldly proposed that Abyss creatures were actually a type of energy life form. The biggest difference between them and life in the prime material plane was very likely that their shells lacked aether element particles.

And to verify this was simple. He just needed to throw an Abyss creature's corpse in the forest and see if it had any effect on the growth of forest plants.

If these corpses didn't contain aether, then very likely the growth of forest plants would only have negative effects, not positive ones.

The second point was that Abyss creatures, like wizards, had limits.

Magical pressure 1000 was a natural moat.

The racial restrictions this Mammon demon spoke of very likely referred to when wizard apprentices broke through to become First Circle wizards and encountered insufficient soul shell strength, unable to continue improving mana.

That is, one must possess a permanent defensive field to continue forward.

The wizard's breakthrough method was to use a permanent defensive field to break through one's soul limits and achieve the first transcendence of limits.

And Abyss demons seemed to use a more primitive method, using mutual devouring to transcend racial limits.

After transcending the first limit, one could become a so-called Abyss Lord.

Then the Abyss Lord tier corresponded to First Circle wizards.

The demon duke tier very likely corresponded to Second Circle wizards.

The so-called Abyss plane masters, Abyss Princes, very likely corresponded to Third Circle wizards.

'First Circle wizards have the power to wage war on planes. Second Circle wizards have the power to destroy a plane below medium scale.' Locke thought, "It seems the world power level of the Endless Abyss planes is very high. Otherwise, it would be impossible to fight back and forth with the wizard world. Even many natural moats exist because the wizard world and Abyss plane worlds overlap, producing Abyss rifts, causing the formation of natural moats between major wizard lands."

Locke thought, 'I used the synthesized Beholder Lord Potion and inadvertently endured the huge side effects, then obtained Abyss energy.'

'But if my previous speculation is correct and Abyss demons are a type of energy life form, then the method they use to judge others' identities is to use the other party's energy characteristics to identify them.'

'So this Mammon demon mistakenly believes I'm a Beholder Lord. The key is that the Abyss energy circulation really was established at my eyes. I don't know what kind of change this is. If I continue exploring, perhaps there will be unexpected gains.'

Locke's expression was strange. At this moment, the Synthesis Cube in the void before his eyes had finished synthesizing. He had previously put three bottles of Beholder Lord Potion in to synthesize, and now it had finally successfully synthesized.

He took it out and discovered that a special synthesis formula had actually appeared.

[Beholder Elder Potion]!

'Beholder Lord Potion can allow me to obtain Beholder Lord-level Abyss energy. What are the effects of this Beholder Elder Potion? What are the side effects?'

Locke looked at the Mammon demon in his hand. He hadn't expected that treating Yuri would actually yield such a great harvest. He had further understood the Abyss.

This had huge benefits for him.

Especially for his Abyss potion studies. Perhaps this part of knowledge could quickly allow his potion studies to reach the First Circle level. At the same time, researching the Beholder Elder Potion formula could undoubtedly also accelerate the progress of his basic potion studies level.
