Holy Purification Resentment Potion

When Lu Yuan rushed back to the Hanging Tower Pharmacy Group from the Research Room near the Training Ground, it was already dark outside. The members who had been busy in the group during the day had all left one after another, and the spacious outer rest area was empty, with only Frey and Lu Yuan, who had just entered, remaining.

Frey was sitting on the leather Sofa, flipping through a notebook she used for taking notes. Hearing footsteps at the door, she looked up and saw the figure entering. She closed the notebook on her lap, her little face becoming very serious.

"The medicinal herbs arrived a long time ago, where have you been? I've been waiting for you for ages."

Meeting her gaze, Lu Yuan quickly smiled apologetically, "I'm so sorry, something came up at the last minute, I went to the Bounty District to pick up a bounty, and I just finished and rushed over."

Frey stared at him for two seconds, then sighed helplessly, "Fine."

She stood up from the Sofa, holding the books, and waved to Lu Yuan, signaling him to come with her. She led him through the rest area and into the room on the left, which was specifically used to store Plague Water and Aura Concealment Potion.

Upon entering the room containing the Plague Water, Frey went straight to the wooden cabinet against the wall, opened the door to reveal a large quantity of medicinal herbs that had been prepared beforehand, and turned to Lu Yuan: "Alright, tell me what your thoughts are."

Lu Yuan's gaze fell on the large bunch of medicinal herbs in the cabinet. Oden, inside the Drowner shell of the left leg, also glanced at it and chuckled in his mind:

"Oh, that's great! With these medicinal herbs, we can start preparing our strategy."

Faced with Frey's questioning, Lu Yuan patiently prepared his explanation. He knew that Frey had played a crucial role in enabling him to obtain so many medicinal herbs so quickly, and he had to explain the situation to her both logically and emotionally.

Lu Yuan's true basis was actually the rational shock brought about by the Plague-Wailing Mushroom, but he couldn't tell Frey his trump card—that he could directly see the names of the medicinal herbs—exactly. He could only explain it in another way:

"I'm wondering if it's possible that the Plague Water contains some kind of ingredient similar to the Pathway Mutation Potion, that could drag people into that special world? But whatever that ingredient is, as long as it's related to reason, it's highly likely it will be detected."

Lu Yuan pointed to the Deceased's Wailing Crystal in the cabinet, then added a touch of Rotspot Grass: "By using both the Deceased's Wailing Crystal and Rotspot Grass, it's possible to achieve the detection effect I just mentioned."

Upon hearing Lu Yuan's explanation, Frey's brows furrowed immediately, and she raised two questions. "If you're going to use the Deceased's Wailing Crystal, what's the point? The Deceased's Wailing Crystal is a kind of impure crystal formed from the resentment of the dead. You can't just give it to people to eat, can you? And you can't use it for testing either."

She paused, then shook her head and added, "As for the effects of the Rotspot Grass,' everyone has already thought of them, but their actual effectiveness is limited because that method is too easy to detect, and the detection is too superficial, making it easy to circumvent."

Upon hearing this, Lu Yuan simply smiled and explained his thought process, or rather, the one Oden had provided. "After special processing, the Deceased's Wailing Crystal' can be cleansed of its resentment, making it a device for detecting specific fluctuations in a person's rationality. All that's needed is to drip blood into it; once the blood's owner's rationality shows a specific fluctuation, needle-like, Spirituality spikes will appear inside the originally transparent crystal, resembling internal cracks."

Lu Yuan pointed to the booklet recording the progress next to him and continued, "Based on this, adding the Rotspot Grass, and combining it with the High-Grade Holy Water color comparison scheme discussed by the Concealment Pharmacy Group in the Master Ledger, we can explore further. As long as the two are combined, there is a high probability that we can find it."

Frey froze on the spot after hearing these words, her face filled with undisguised shock.

What shocked her wasn't how ingenious Lu Yuan's combination method was, but that Lu Yuan actually knew a method she had never even heard of before: to make the Deceased's Wailing Crystal, Ore full of resentment, capable of detecting potions and materials—something she had never heard of before.

However, if what Lu Yuan said is true, then this path does seem to be feasible.

While the Ore Testing Theory had indeed been proposed in the Master Ledger before, no good ideas had been developed. However, if Lu Yuan's crystal proved feasible, then the possibility of deciphering the Plague Water would no longer be merely theoretical, and the chances of success would be greatly increased.

Frey snapped out of her daze and, without standing on ceremony with Lu Yuan, took a half-step forward and asked, "Since you can make it, can you process it now? Can I watch from the side?"

Lu Yuan nodded readily, indicating that there was absolutely no problem.

He wasn't worried that Frey would learn his techniques from seeing him work on the Deceased's Wailing Crystal.

The reasons are simple. First, Lu Yuan still trusts Frey's character. Second, Oden said that his method is very difficult and most people can't learn it, especially the formula for the potion. If he just covers it up a little, by the time Frey figures it out, it will be too late.

So Lu Yuan didn't hide anything and just let Frey stay by his side. Besides, Frey's rationality was already somewhat lacking, and her current state wasn't very good either, so it was fine for her to just watch from the side and not touch the potion.

Seeing that Lu Yuan had agreed, Frey obediently moved a small stool from the corner and sat properly next to Lu Yuan, watching Lu Yuan operate.

Lu Yuan walked to the control panel and began to communicate with Oden. Oden instructed Lu Yuan to follow his method to first create a medicinal liquid to condense the Deceased's Wailing Crystal and process the impurities inside. The core of this method was to use the Holy Light Vine, along with the five Purification materials from before, to dilute and dissolve the crystal, and finally re-condense it into a special, beautiful snowflake-shaped crystal.

Lu Yuan laid out Purity Grass, Dawnflower, Moon Dew Grass, Chalk Root, and Plague-Cleansing Leaf on the table one by one. First, he put Purity Grass and Chalk Root into a stone mortar and ground them into an extremely fine powder. Then, he used a vessel to extract the extracts of Dawnflower and Moon Dew Grass little by little. Next, he put Plague-Cleansing Leaf into Heating Cauldron and simmered it over low heat until it was blended. Finally, he added the juice of Holy Light Vine into the medicinal liquid little by little.

Once the liquid used to condense the Deceased's Wailing Crystal was completely produced, a line of Gray-White Text popped up before Lu Yuan's eyes.

[Pharmacology: +1...15.2/50]

Lu Yuan looked at the clear liquid in front of him, and then new Gray-White Text popped up in front of him.
