Locke invited Yuri to enter his laboratory.

As soon as Yuri entered the laboratory, she immediately looked around, because floating inside the tissue culture liquid tanks in the laboratory were many eyeballs.

These eyeballs were actually from different magical creatures, and among them were many magical creature subspecies related to Abyss creature bloodlines.

When Yuri connected this with Locke's reputation as the Eye Demon wizard circulating outside, she was immediately startled and looked at Locke with some trepidation. Only now did she remember that Locke was a First Circle wizard with a fierce reputation.

Locke glanced at her and said, "Oh, these are just byproducts from my previous research on Abyss potion studies."

"Lie down on this operating table. I already have a general idea of your problem."

At this moment, Yuri could only obediently lie down on the operating table.

Locke's right hand passed over her face, and immediately spell models struck her body. "The so-called Abyss Potion Material Paradox was proposed by a First Circle wizard of the Green Ring Society in the past, a formal potion master. He discovered that adding Abyss creature materials to a potion formula would make the quality of that potion formula better."

"This is because the energy level of Abyss creatures is very high. As long as high energy-level materials are added to a potion formula, it can make the reaction speed of the potion faster and the medicinal effect better."

"But adding Abyss creature materials leads to serious side effects, and these side effects don't increase linearly or surge suddenly, but rather... are completely random."

"In this paradox, adding Abyss creature materials improves the potion's effect, but it might also turn the potion into a completely undrinkable poison."

Locke beckoned with his hand, and immediately a potion entered his hand. A red eyeball floated inside it. Locke opened the potion bottle cap, and immediately something inside Yuri's body seemed to sense the aura of the Beholder Lord Potion and began to become restless.

Locke keenly noticed that Yuri's shadow... began to twist eerily.

Locke said, "That wizard was also the main culprit behind the Abyss Plant Catastrophe. In his paradox, he also hypothesized that perhaps someone could find a method to limit the side effects of Abyss materials through specific potion formula combinations." 𝒇𝙧𝙚𝓮𝔀𝓮𝒃𝙣𝓸𝒗𝒆𝒍.𝙘𝒐𝒎

"The Green Ring Society's research on Abyss creatures not only caused the largest-scale loss of control of breeding magic experiments in the southeastern quadrant a hundred years ago, causing endless harm, but also caused considerable harm in potion studies."

"There is a batch of potion master assistants with average qualifications. In order to publish articles and obtain better data, when they cannot improve formulas, they attempt to use Abyss materials to increase the potion's effect."

"But their abilities are insufficient. They don't know that all Abyss materials need to use magical flames before refinement to remove the Abyss polarity. So I suspect you once drank some Abyss creature material."

Locke looked at Yuri's shadow. "I guessed correctly."

Yuri turned her head to look at her own shadow and was also startled. She saw that her shadow cast on the ground by the magical lamp actually had a ghostly hand gripping her neck, refusing to let go.

That 'ghostly hand' gripped her neck. Countless amounts of life energy were being absorbed by it to recover its injuries and missing body parts.

This was the truth.

The aging curse on her body had long been removed. She shouldn't have aged anymore, but twenty years ago, the remnant body of a demon had been drunk down by her through an immature potion. Since then, it had secretly parasitized her body, absorbing her life force.

Ordinary potion master assistants couldn't detect this extremely deeply hidden demon.

And First Circle wizards hadn't carefully examined Yuri. Even if they had examined her carefully, unless they had studied Abyss potion studies, they would need to observe continuously for at least a week. Otherwise, they couldn't detect the clues.

This was also why Yuri had always been misdiagnosed.

The ghostly hand on the shadow suddenly opened a black eye full of chaos and disorder at its palm. The surrounding light seemed to dim by several degrees. The negative energy particle field throughout the entire laboratory was completely altered, reversing in an instant.

"Give me... give me that bottle of potion... give me..."

Locke raised his eyebrows in surprise. So that was it. Abyss demons had the characteristic of reversing negative energy particle fields?

This point seemed to be less researched by white wizards, possibly because wizards of the southeastern quadrant rarely came into contact with Abyss creature demons.

The ghostly hand looked at the Beholder Lord Potion in Locke's hand with extremely greedy eyes. It could sense the rich, pure, and high-quality Abyss energy contained within that bottle of potion.

In the southeastern quadrant of the wizard world, there was actually a wizard who could extract such high-purity Abyss energy.

This was truly beyond its expectations.

"Quickly, give me that potion. Otherwise, I'll kill this woman."

The ghostly hand suddenly exerted force and grabbed the neck of Yuri's shadow. Immediately, Yuri lying on the operating table screamed. Her magical pressure was actually completely suppressed by the ghostly hand. She couldn't resist the ghostly hand's assault. As long as the ghostly hand struck to kill, her already fragile life energy would be obliterated in an instant.

Locke's gaze was indifferent. He didn't speak, only looked at it coldly.

'It doesn't seem to be the lowest level Tanar'ri demon with little intelligence. But rather some kind of relatively high-level demon.'

'Over twenty years ago, it might not even have had a single hand's worth of body. All these years, has it been secretly stealing Yuri's life force to repair its flesh?'

'Wait a moment.' Locke suddenly thought. 'That's not right. Doesn't repairing a body require large amounts of aether element? The body is flesh and blood. How could it simply parasitize on someone else and recover by absorbing life energy? Even if it has energy, it's useless because it doesn't have a physical body, or the large amount of aether to construct a physical body.'

'Unless... demons originally don't have physical bodies, but that's also not right. Wizards have battled Abyss demons. They do have physical bodies.'

Locke thought, 'Then their physical bodies must be special and aren't the flesh and blood life of normal life forms.'

The ghostly hand let out a shriek. "Quickly give me that bottle of potion. I only want that bottle of potion. If you give it to me, I'll leave this witch's body. Otherwise, I'll kill her and perish together with her."

"I only want that bottle of potion. Wizard! Give it to me!"

Locke directly drank the Beholder Lord Potion in front of this ghostly hand. The ghostly hand immediately let out an enraged roar of madness, but the next moment, Locke instantly appeared in front of Yuri's shadow. His right hand directly reached out and grabbed the ghostly hand, squeezing with force. The ghostly hand almost became deformed.

Locke grabbed it and directly pulled it out from Yuri's shadow, gripping it in his hand and looking at it coldly.

"A mere demon dares to threaten me. Who do you think I am?" A fierce gleam flashed through Locke's eyes. Golden vertical pupils flashed in his pupils, and at the same time, Abyss energy flashed within.

This demon instantly sensed the terrifying aura emanating from Locke's body. "Lord... it's the aura of a Lord..."

"It's a Lord of the Abyss..."

"How can you have energy at the Abyss Lord level! Heavens, could it be that you're a Lord of the Abyss!"

The ghostly hand cried out in alarm. Locke frowned. What the hell? The other party seemed to have made some kind of erroneous judgment because of his aura.

His Abyss energy came from taking the Beholder Lord Potion. The Beholder Lord Potion was synthesized from three bottles of Beholder Potion.

Wait a moment.

Locke probed, "What level of demon is the Beholder Lord in the Abyss?"

The ghostly hand became very fearful and kept trembling in Locke's hand. "Replying to Your Excellency. It's a Lord-level demon... Beholder Lords have extremely long lifespans. There's even a Beholder Lord who is the master of a first-layer Abyss plane's Abyss world."

Locke said, "Then what are you?"

The ghostly hand said fearfully, "Beholder Lord, sir. I am a Mammon demon, a greed demon born from the combination of greed energy and dark energy particles under the influence of Abyss energy."
