Chapter 479: Secret Servant

In the synthesis formula of the drug, the doctor occasionally used terminology Xia De didn't understand to refer to certain additives. Although Xia De's understanding of herbs and magic potions was very shallow, judging from the synthesis method and the order of adding the medicine, this "Red Potion" was very likely the active ingredient.

"This is... it's a high-purity synthetic drug from a friend of mine at the Third Mechanical Academy of Tobesk for my laboratory."

"Lie."

The black-haired young lady, who was looking down at the medical records, said without raising her head. The sweat on Mr. Alfred's face flowed down along his side face immediately. Xia De shook his head and put down the notebook in his hand:

"Doctor, I have reason to believe that the so-called 'Red Potion' is a powerful hallucinogenic drug you bought from the black market. This unknown illegal drug stimulated Mr. Bondi's eyes, and also caused him to fall into addiction and hallucinations, eventually leading to the tragedy of suicide."

"It's absolutely not a hallucinogenic drug! I tested it myself! It's just used to treat eyes."

Mr. Alfred said loudly again, but stared at by Xia De's examining gaze, he actually felt a sense of inexplicable fear toward the young man in front of him.

"What exactly is the Red Potion?"

He asked, staring into the ophthalmologist's eyes. The middle-aged man trembled timidly, but still looked at him bravely.

The two stared at each other for a long time. Xia De didn't show any fierce temperament, nor was he as scary as the gangsters he saw in the nearby street area, but the more he stared at Xia De, the more the inexplicable pressure made his heart feel cold, as if he were looking up at some indescribable behemoth.

In the end, the doctor gave up hiding and shifted his gaze somewhat dejectedly:

"That is... a gift from my ancestors."

Xia De sighed and turned to look at his assistant. The maid looked very expectant of the story, while Xia De felt that this troublesome matter was finally coming to an end.

And compared to Xia De's investigation process, Dr. Alfred's story was relatively boring.

The doctor wasn't a local of Tobesk; he settled here from out of town. Although he successfully gained a foothold in this big city known as the Pearl of the North, Jacob Alfred still returned to his hometown to take a look every year.

And when he returned home this spring, the doctor considered selling his old family house to obtain cash to expand his clinic in Tobesk. While tidying up the old house, an earthquake unexpectedly occurred locally. The earthquake caused cracks in the basement wall of the old house, and behind those cracks, Dr. Alfred discovered a hollow dark compartment used to place items. There were three items in the compartment: a bottle containing red medicine, a parchment scroll written in an unknown language, and a ring.

"Truly wonderful!"

The maid said in a low voice.

"These are all. I don't recognize the words on the parchment, and the ring looks like an antique. As for those medicines, although I don't know the specific function, I saw the symbol of an eye on the parchment, so I thought it might be useful for eyes. Later, I experimented on white mice and found it was indeed useful. Later, I added some other herbs myself, so it could work on people. Mr. Bondi was my first experimental subject. I really succeeded; he really recovered his sight."

Dr. Alfred took out an old leather suitcase from the safe, carried it to the coffee table, and after unlocking it with a key, opened the suitcase and took out the three items and placed them on the table. Among them, the red liquid in the yellowing bottle only had three-quarters left, and the others were prepared into that kind of bright yellow medicine. The parchment looked quite ancient, and the words on it were indeed ancient languages.

As for the last ancient square-faced iron ring...

【Outsider, you have touched "Whisper."】

"Oh? Relic?"

"Is it a Relic?"

The maid was somewhat surprised. Without knowing the specific characteristics, it was very difficult to discover a Relic that hadn't taken effect. And Xia De's soul was sensitive, so he could make a judgment quickly.

He put on gloves and took the ring in his hand, and the voice in his ear directly confirmed that this was a Relic.

The ring's band was black-iron colored, and the ring face was a deeper, ancient black-iron material. The ring face was rectangular, with the edges slightly convex and the center concave, but the pattern inside the rectangle was convex.

Xia De suddenly widened his eyes:

"Can a ring also count as a seal?"

This was an ancient metal seal ring, and the pattern of the seal...

"Knock, knock, knock~"

The three looked at the study door behind them together. The suddenly ringing knock didn't bring too much fright, but they all felt their hearts go cold at this moment.

The person outside the door was knocking on the door panel with great regularity, without any intention of stopping.

"Doctor, may I ask, are there any other people in your house?"

Miss Servit frowned slightly and asked. Looking at the doctor again, after confusion, a terrified expression climbed onto the doctor's face:

"No, before you came, there should have been no other people here. Someone broke into my place! Oh, who is it, who is outside!"

He asked loudly, but no answering sound came from outside the door. The knocking maintained its original frequency, but the sound became louder and louder.

Miss Servit stood up:

"Detective, be careful."

She and Xia De both felt an abnormal feeling coming from outside the study door.

Letting the doctor hide under the desk, Xia De also stood up.

Cold wind quickly drilled in from the door crack. It was clearly a late summer afternoon, but the light in the area where the door was located dimmed suddenly, as if something was absorbing the light.

In just a few seconds, the two standing in the middle of the study saw that the doorway area had already fallen into pitch darkness. The door completely disappeared into the darkness, and the knocking sound also seemed to be completely absorbed by the darkness, disappearing without a trace.

"What is this?"

Tifa asked in a low voice, taking a step forward and blocking Xia De behind her. Miss Galina let her follow Xia De, and one of the orders was to protect Xia De.

Xia De rubbed the ring face of the metal seal ring in his hand with his finger pads, and then carefully put it on his index finger. He already knew what this Relic was. The seal pattern on the ring face was exactly the exorcism emblem on Riddle, the prophet of the Fifth Era.

This was the 【Seal of Demon Hunting】, the mark of the Demon Hunters of the Third Era hunting evil spirits and demons. Xia De had only heard Luweiya say yesterday that he would definitely run into it as long as he kept walking forward, but he didn't expect this seal to actually be a ring.

If he had seen it was a seal just now, he absolutely wouldn't have touched this ring.

"I think it was probably attracted by this ring, a demon. Once this ring is not held by a Ring Ringed Ringed Shushi for a long time, it will attract demons when it encounters a Ring Ringed Ringed Shushi again. This is one of the negative characteristics, as if the original holder of the ring hoped that the next owner of the ring could understand their mission."

Xia De said in a low voice.

"What?"

The maid once thought she had heard wrong.

"This ring is a Relic, and its negative characteristic is attracting demons. I don't know why it appeared in my hand when I was looking for it, and I don't know why there are demons in the Tobesk city area, but now the demon has come, the evil spirit demon left over from the Third Era has come."

He walked toward the darkness that was constantly squirming and spreading forward, but his right hand was pulled by Tifa. The maid frowned tightly, and asked with a serious expression:

"Wait, Mr. Hamilton, what do you want to do?"

"Of course, it's to experiment whether I can actually fight this thing. It's not powerful, yes, it's not powerful."

This was also the reason why Xia De didn't immediately climb out the window and escape. The Weak Angel Potion was on his body, and the 【Seal of Demon Hunting】 was also obtained. It just happened that a demon considered relatively weak by "her" appeared, and the Outsider wanted to test whether the weapon he had worked hard to prepare was effective.

Miss Servit couldn't believe it; the Second Tier Xia De thought the terrible creature that brought darkness wasn't powerful:

"Mr. Hamilton, I know what this is. This is a Secret Servant that walked out of the out-of-control Angel-level Relic 【Darkness Domain】 outside the city. It brings darkness to swallow the light, expands the scope of the darkness domain, and tries to make the whole world fall into forgotten darkness. I must ensure your safety, we must leave immediately!"

Meaning she could deal with this thing, but with Xia De by her side, she couldn't take risks.

"Secret Servant? Oh, so it's a derivative of an out-of-control Angel-level Relic, I've heard of this... So, I can't leave even more."

Seeing the maid still pulling him, he explained again:

"Please rest assured, what I fear most is darkness, darkness cannot swallow us."

"Detective, are you worried that this darkness will spread in the street area and swallow more humans, so you don't want to leave?"

The maid asked in disbelief.

"Why would you think that? Even if I am a good person, I'm not good to that extent."

His expression was equally serious, looking at his assistant for today:

"Miss Servit... No, Tifa, do you think I am the kind of person who seeks his own death?"

He called the young lady in front of him by her name directly.

"When Miss Galina takes you to handle things, how do you perform? Tifa, although you are not wearing a maid's dress now, please restore your normal state as a maid."

"But..."

"I won't boast about myself in front of a beautiful young lady for the sake of face, and I won't rely on your strength just because you are by my side. This time, you are a maid, you are a detective's assistant, please obey my orders. Hold my hand tightly, and come with me to solve this thing."

He looked into Tifa's eyes. After the latter looked at his serious expression and blinked, her expression relaxed a little:

"But I must emphasize two points. First, if we really encounter danger, we will retreat immediately. Second, before the Young Lady decides to marry you, you are not my master yet, so please don't order me."

Xia De nodded:

"Yes, Miss Tifa Servit, maybe you really need to protect me in a while. But at least now, please hold my hand tightly and don't be swallowed by the darkness."

The two hands held together, Xia De stepped forward first, and then they walked together into the darkness that was squirming and spreading forward in front of them.

Stepping from the normal area in the study into the edge of the darkness, although there was no spatial movement, the body still felt a state of weightlessness. But what the black-haired young lady cared about wasn't that momentary weightlessness, but that after entering the darkness, the darkness wrapping from all directions almost melted her body and took away her soul in the next second.

This terrifying hallucination of being swallowed by darkness didn't last long before a faint light dispelled the abnormal emotion.

She saw the hand she was holding glowing slightly, and then saw Xia De emitting that pure, heart-moving holy silver light all over his body. It seemed that because the two were holding hands, this light also slightly attached to her body, keeping the surrounding darkness away.

"Look, darkness cannot swallow me."

Xia De said, and both of them summoned their Life Rings. The darkness also couldn't swallow the dazzling light of the four colors on Xia De's Life Ring. Because the two Life Rings were too close, the two metal rings appeared in the steam mist, and sparks were rubbed out during the high-speed rotation, before slowly adjusting their size and drifting in opposite directions.

"The plan is like this. Find the demon, and then kill it. How do you feel?"

Xia De asked, looking at the surrounding darkness.

"A very simple plan, but how are you going to find the other party? Are we waiting for the other party to attack us?"

Tifa also looked around.

"No, no, please wait a moment... Silver Moon!"

The silver light on his fingertips flashed slightly, completely unable to dispel this darkness. This was the first time the light of the Silver Moon had no effect, but it was also within Xia De's expectation. After all, even the Sage-level Relic 【Fish Bone Pirate Ship】 could suppress the moonlight, so it was normal for an Angel-level Relic specifically targeting light to be more powerful.

"In that case, I have to touch this darkness more deeply."

Taking a deep breath, he inhaled the air into his lungs. Listening carefully for a moment, after getting a hint, he led Tifa forward.

The area covered by the darkness wasn't big itself. This wasn't a spatial anomaly, so in the case of choosing the right direction, it was only a dozen steps before an abnormal sound appeared in front. ===== CHAPTER 480 =====
