I can see experience bars after being transported to another world.

Lu Yuan indicated that he understood.

The Knight with the Lantern took a small booklet from his pocket and handed it over.

"These are all the medicinal herbs she used that night, checked one by one against the medicine cabinets in both rooms."

Lu Yuan looked down and saw that the booklet contained seven kinds of medicinal materials, three kinds of herbs, three kinds of materials from the strange creature, and a kind of stone.

Among the three herbs, one is called Filtering Hair Grass, whose leaves are covered with fine hairs that can trap impurities when passing through the medicine, allowing only the clear liquid to pass through.

Among the three strange materials, one is called lizard molt, which is the molted shell of a lizard. When used in medicine, it can promote the separation of mixed components into layers.

The last type of stone is called a water-dividing stone. It can absorb the water from the medicinal liquid, but it may not absorb anything else, only water.

Of the seven medicinal materials, the amount of water-separating stone used is the largest, and the other ingredients are also related to separation.

"They're all medicinal herbs related to separation." Auden's voice echoed in Lu Yuan's mind after just one glance. "I think I know what that girl was thinking back then."

"She probably used a lot of water-separating stones to separate the medicine from its active ingredients, and then tried to work backward to figure out the main materials. I guess something happened after the separation, and some amazing thing was extracted, which led to that situation."

"But what kind of material, contained in just a tiny amount in the medicinal herbs, could cause such a horrific scene?" Oden's voice deepened. "That's what we need to be wary of."

"There's a strong possibility that this potion contains something that can lure out that illusory place," Oden continued. "This thing is so potent that it can hardly be called a potion anymore."

Lu Yuan's heart stirred slightly. He raised his head and looked at the Lantern Knight.

"May I take a look at that bottle of medicine first?"

The Knight with the Lantern did not refuse. He went deep into the room, retrieved a vial of potion, and moved very quietly.

This was the first time Lu Yuan had ever seen a legitimate path to mutation.

The bottle containing the potion was the same ordinary glass bottle used for sanity-stabilizing potions, with a vibrant light blue color and specks of gold floating in the center.

From its appearance, there was almost nothing suspicious about it; in fact, it was surprisingly beautiful. Based on its looks alone, no one would associate it with the term "pathway alienation."

Lu Yuan took the medicine and stared intently at it.

This is a good opportunity to take a good look at what's hidden inside this potion.

Grayish-white text slowly emerged.

[Alchemy artifact detected: Invitation from the Silent Land (???)]

[A special alchemical artifact inviting you into the desolate lands. Perhaps you will find something unexpected within that territory.]

Lu Yuan's eye twitched involuntarily.

The description given in gray and white text was completely different from what he had imagined. All his initial guesses about this potion were completely overturned at this moment.

Moreover, the composition of the drug was not described.

Clearly, it has exceeded Lu Yuan's capacity to bear it, or rather, it has exceeded the scope of his observation.

Oden noticed Lu Yuan's silence and did not disturb him.

"I can't see its specific composition." Lu Yuan silently put the potion back on the table and said to Auden in his mind, "The only thing I'm sure of is that this thing is also related to the Dead Lands."

"Frei must have triggered its effect, the path mutation it brought about, which Frei triggered prematurely using other methods, resulting in memory loss, which is quite bad."

Oden did not respond.

Over the past few days, he had long since taken note of Lu Yuan's ability to examine information. It didn't seem to have any particularly obvious limitations on people; however, the observation time required varied depending on the other party's rank. Staring at someone like the Rock Knight Commander required a great deal of time, while examining items required only a very short time, a mere instant.

When observing certain medicines, there may be situations where some parts are visible and others are not, which means that this ability is likely limited, for example, depending on the scarcity of the materials or Lu Yuan's own knowledge.

"That's truly an impressive ability," Auden thought to himself. "Of all the extraordinary abilities that Forbidden Science has possessed so far, Lu Yuan's is definitely in the top three, based on his current performance."

I wonder what abilities he will awaken after reaching the fourth or fifth tier? If he remains this powerful, the rise of forbidden science will be a foregone conclusion.

Auden didn't utter a single word of these thoughts to anyone.

"It's normal that you didn't notice," Oden said. "Judging from Frey's performance that night, this thing can no longer be called a potion. At least, it's definitely wrong to describe it as a potion. It's more like some kind of alchemical product."

"Who makes ordinary potions this way? How could it possibly summon a phantom from another world?"

Lu Yuan grinned.

Oden was right; the ability might not have worked, so there was still some disappointment.

However, it wasn't particularly difficult. He had long since figured out that the effectiveness of his abilities depended primarily on himself; the more avenues and knowledge he had, the more information he could access. Theoretically, given enough time, he could analyze everything in the world.

But before that, he needs to read more books and learn more.

The Knight with the Lantern smiled as he looked at Lu Yuan's furrowed brows and somewhat bewildered expression.

"The reason I didn't want you to get involved in its research before was purely to protect you," the Knight with the Lantern said. "This potion looks extremely ordinary, even quite deceptive, which is the main reason I didn't want you to get involved with it, plus Frey's current condition."

He sighed.

"Now that you've made your decision, let's begin the work of deciphering and reverse-engineering it. Before we start, there are two rules you must remember."

"First, this medicine must not be touched in any way. The liquid must not come into contact with yourself, otherwise it may have an effect. This is a conclusion reached through testing."

"Secondly, it is extremely rare, so we must use it sparingly. Our current inventory is not particularly large either."

As the Knight with the Lantern finished speaking, he glanced at the bottle of potion beside Lu Yuan with a pained expression, as if he had thought of something.

"By the way," the Knight with the Lantern changed the subject, "having seen these medicinal herbs, what method do you think Frey used back then?"

When he said this, his expression clearly indicated that he already had an answer, and he looked at Lu Yuan, waiting for a reply.

Frey, who was next to her, opened her mouth, then closed it again.

Lu Yuan did not answer immediately; he looked down at the seven medicinal herbs listed in the booklet.

He knew in his heart that this was the Knight of the Lantern's first test for him. If he could roughly figure out the proportions and methods of using these herbs, even if they were different from what the Knight of the Lantern thought, as long as there was some logic and feasibility, he would pass the test and then he could start working on deducing how Frey used the potion that night.

There wasn't much medicine available, and we couldn't afford to waste it.

The Knight with the Lantern didn't urge him on, and continued talking to himself.

"The reason I didn't let you participate before wasn't just for your safety," the Knight with the Lantern continued. "Although everyone in the group has the Intermediate Pharmacology Certification, there's a huge gap between people. Some people can indeed come up with brilliant ideas after passing the certification, and even come up with very specific solutions, but most members' abilities are not yet sufficient to research pathway mutation potions."

"In the entire academy, there are only a handful of people who have passed the advanced pharmacy certification, and most of them are not currently on campus. I myself am only an intermediate level, and my level is even lower than that of other students in the academy who are studying pharmacy. That is why I have not taken action myself."

"The String Knight does have advanced pharmacology certification, but he is too old, and there are other things to prepare, so the academy ultimately rejected his personal participation in the project."

"There's another reason. After the String Knight initially reviewed the potion, he concluded that the reverse reasoning didn't hold true. To be precise, he never even thought the mission would succeed."

"His exact words were that the ingredients used in the drug are all very rare, and its effects and principles are almost impossible to replicate. In addition, the quantity of the drug is extremely small, so he did not recommend starting a reverse engineering project."

"But considering the threat posed by this potion, after evaluation, the academy reluctantly launched a countermeasure project, which fell to our group."

"Actually, what the academy is really concerned about is the harm caused by the aura concealment potion and the plague potion. Even though the pathway mutation potion is indeed very effective, as long as one does not intentionally drink it or is forced to take it, the threat it poses is relatively small. Moreover, once a person's pathway is contaminated, it is relatively easy to detect."
