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

In Frey's view, after listening to her words, Lu Yuan suddenly fell into a brief silence, his brows furrowing deeper and deeper.

She thought Lu Yuan was frightened.

"Hey, but don't worry," Frey reassured her. "We've tested this potion, and it won't have any effect unless you drink it. And it's not as scary as you think. One bottle isn't enough to completely transform a person; theoretically, you'd need to drink many bottles."

Lu Yuan and Auden were both puzzled. So many bottles? Would this person even drink them? Anyone with a brain should notice something was amiss, right?

Frey looked at Lu Yuan, as if she had expected him to ask this question.

"The truly terrifying aspect of this potion isn't its ability to change a person's path, but rather its ability to lower their guard and make them dependent on it. A normal extraordinary expert might not have the strongest willpower, but they are definitely among the best of their peers. So no one would be so foolish as to believe a potion handed to them by someone else, even if it were secretly given to them. One bottle of this potion isn't enough to directly transform them. And as long as you stop taking it, there won't be any problems."

"But that's also the most terrifying thing about this potion. It can relax a person's resistance to it, and after taking it, a person will experience varying degrees of relaxation in their guard. Some people relax more, and some relax less, but so far, we still can't confirm what happened."

Does the influence of the mind vary from person to person?

"How can there be such a potion? And how can it produce different effects on each person? Could it be because some people have stronger willpower and some have weaker willpower?" Auden muttered in Lu Yuan's mind.

Upon hearing this, Lu Yuan relayed Auden's words.

Frey shook her head. "No, if only it were that simple. We've caught a few people who took this kind of drug, but from our observation, its effects don't seem to depend on a person's level of rationality, or rather, the strength of their pathways. On the contrary, some people with weaker pathways are less likely to let their guard down. So, for now, we can't explain it."

Frey sighed as she spoke, "Those who don't understand the situation are the most frustrating."

After saying that, Frey didn't say anything more. She just pursed her lips and stared at the door on the right for a while.

"How long has this mission been running?" Lu Yuan asked casually. "Has there been any substantial progress?"

Frey paused for a moment, then shook her head.

"This mission has only been underway for a little over a week so far, and there hasn't been any substantial progress regarding the mutation potion. On the contrary, there have been some new discoveries regarding the potion that conceals the aura. As for the plague potion, there hasn't been any development either, and the structure of that plague potion is a bit strange; we still haven't figured it out."

Frey's tone revealed a hint of helplessness.

"These heretics are not only secretly tempting people with weak minds to drink the path-altering potion, but they are also constantly spreading the plague potion among the population. Now the northern refugees who have been accepted have become a problem because there are still some obstacles to testing the plague potion. We cannot tell which people have it lurking in their bodies and which people are healthy."

"Alright, I'm not going to talk about this anymore, it's just adding to your troubles."

Frey waved her hand, as if tossing all her worries aside, and led Lu Yuan deeper into the room as she spoke.

"Since you're new here, we need to make some protective arrangements for you. To prevent any problems from arising, you won't be allowed to come into contact with the pathway mutation agent for a while. For now, you can only decipher the plague potion and the aura concealment potion. Currently, only the aura concealment potion has made some progress; the other two haven't shown any significant progress so far."

With that, Frey led Lu Yuan through the archway on the left.

As soon as the door opened, a large number of medicine cabinets came into view, with a huge quantity of medicinal herbs displayed inside. Three of the four walls of the room were surrounded by wooden cabinets, on which were placed a large number of research instruments and some medicines that had not yet been studied.

On the cabinet in the corner were a large number of semi-finished potions, and directly above the table was a metal box engraved with numerous inscriptions. Judging from this arrangement, the contents of that box were most likely samples that the Knight Academy had obtained from somewhere.

"Did you see those books tucked away in the corner?" Frey explained to Lu Yuan. "If you have any ideas or make any progress, you can record them in those notebooks. The group leader of the day will review and approve them every day and report them to you so you can get your own Knight's Token. Of course, you can also break through based on what others have done. If you succeed, the academy will give you a lot of rewards, so you can rest assured and don't have to worry about stealing credit."

Lu Yuan expressed his understanding, saying that this setting was very reasonable.

"You've successfully checked in for today."

Frey tossed a notebook for taking notes to Lu Yuan.

"The Knight with the Lantern actually told me that you won't be handling anything today. What you need to do today is look at the booklet over there, see what our people are thinking and what difficulties they've encountered. If you do this, it will be much easier for you to handle these potions later. After all, this reverse-engineering potion is a rather difficult task, and we can't let you do it all by yourself."

Lu Yuan didn't stand on ceremony. He certainly wouldn't miss such a good opportunity to exchange ideas, but after thinking about it, he still asked one more question.

"If I'm working backwards to deduce the drug, is there an upper limit to the number of samples I need?"

"Each person can only use one bottle of each potion per day, meaning everyone has one bottle of concealment potion and plague potion left over," Frey continued. "If you want more, you must produce something, or discover something, and it will only be given to you after my approval. Otherwise, it is absolutely not allowed. Because these samples are very precious, extremely precious. We used a lot of manpower to obtain them from the heretics."

Lu Yuan understood upon hearing this.

After Frey saw that Lu Yuan understood, she didn't say anything more.

"Ask me if you don't understand anything. I need to figure out the pathway mutation potion. If nothing unexpected happens, I should be here all night."

As she spoke, she walked out, her small figure quickly disappearing through the doorway.

With the door closed, Lu Yuan was soon left alone in the room.

Lu Yuan remained standing in place, his gaze first falling on the open booklet, then slowly moving to the metal box with inscriptions engraved on it at the top of the table.

The night is still long.

Lu Yuan didn't rush to flip through those booklets. Before starting his work, he needed to figure out one thing: whether the materials these potions were made of, and whether his gray and white writing could actually be seen.

If he can see it, everything will be easy; if he can't see it, then he can prepare for the subsequent counter-propagation drugs.

The protective inscriptions on the potions were very well done; he didn't notice anything unusual about them before opening them.

As the box was opened, an unsettling aura seeped out.
