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

Upon seeing this, Lu Yuan decided to use option two without any hesitation.

Because Lu Yuan only had three Hope Leaves, which were genuine life-saving items, and he had only just met Frey, he was a little reluctant to part with them. Of course, the most important thing was that the success rate of Plan Two was also very high; otherwise, Lu Yuan might have had to reluctantly give them up right now.

Most importantly, the sanity stabilizing potion is something the potion team already has on hand.

So Lu Yuan quickly went to the place where he had gotten the holy water before, took out a bottle of sanity-stabilizing potion made from high-grade holy water from the row of potions, quickly went to the sofa, pried open Frey's mouth, and poured it down her throat.

Frey seemed to be resisting Lu Yuan's actions. Her eyes were tightly closed, her eyebrows were twisted, and her head was slightly raised, as if she wanted to break free from Lu Yuan's hand.

Lu Yuan wasn't going to be polite to her. If Frey continued to struggle, Lu Yuan was prepared to break her jaw.

Seemingly sensing Lu Yuan's strength, Frey ultimately did not break free and obediently drank a bottle of sane stabilizing potion.

As the potion entered her mouth, Frey's condition gradually calmed down. Clearly, the potion was taking effect, and her somewhat rapid breathing gradually quieted down.

Just then, the two lines of gray-white text that had been indicating pollution at the edge of Lu Yuan's field of vision suddenly stopped and disappeared the next moment.

Lu Yuan suddenly looked up at the slightly ajar door on his right. As the Frey Path stabilized, the illusory opening seemed to have disappeared, and the door was completely closed.

But Lu Yuan had no intention of going to investigate. If you don't court death, you won't die. The most important thing is to rescue Frey. Then you can just ask her yourself. Why go looking for death?

Suppressing his curiosity was Lu Yuan's assessment of the current situation.

As Oden watched Frey's condition gradually stabilize, he breathed a sigh of relief. It wasn't because Frey was alright, but because he felt sorry for Lu Yuan. He knew that Lu Yuan and Frey were both involved in the field of potion studies, and if Frey had any problems, Lu Yuan would definitely have been held accountable.

The rules of the Knight Academy are very clear: their primary responsibility is protection. They cannot allow their classmates to fail to provide medical assistance. Even if Lu Yuan goes to help but fails, no one will say anything. However, it would be unacceptable for Lu Yuan to stand aside.

"Hey, maybe Lu Yuan can actually benefit from this misfortune and gain something from it?" Auden thought.

Just then, footsteps suddenly came from outside, and then a figure rushed in hurriedly. Lu Yuan looked closely and saw that it was the Lantern Knight.

After the Knight with the Lantern rushed in, he looked at Frey lying on the sofa and at Lu Yuan, who was still somewhat alarmed. He then glanced at the lamp that had turned from red to yellow and his brows furrowed tightly.

"What happened?"

"I came over tonight to work on the potion countermeasure." Lu Yuan carefully chose his words. "Frei seems to have done something, summoning a phantom, and her sanity and pathways seem to be affected by it, as if they have been transformed. I fed her some sanity stabilizing potion, and she is in much better condition now."

The Lamp Knight's gaze fell on Frey's tightly closed eyes and the slightly red and swollen handprint on her small face.

He didn't say anything to Lu Yuan, because the simplest physical stimulation is a good way to help regain rationality, so Lu Yuan did nothing wrong.

"You did a great job," the Knight with the Lantern praised Lu Yuan.

Then, he picked up the small lamp made of an unknown material from his waist and circled it around Frey. The light on the lamp flickered, and then gradually stabilized. Only then did the Lantern Knight breathe a sigh of relief.

"It seems like nothing too serious has happened. Where is Frey's research room? Is it the pathway mutation potion?"

Lu Yuan nodded, and the Lantern Knight followed Lu Yuan's instructions, preparing to go to the room where the mutated potion was being researched to see what had happened. The Lantern Knight was very careful, carrying the small lantern in his hand and walking cautiously ahead.

The door on the right was now open, leading to the research room for the mutated drug. Everything was as usual, as if nothing had happened, and there was nothing obviously abnormal. There was no trace of any eerie atmosphere left in the room.

The Knight with the Lantern stood at the door for a long time, but the lantern in his hand did not react at all.

He frowned and turned to ask Lu Yuan if there were any more detailed information.

"When I sensed the unusual atmosphere, I rushed in, but I didn't dare look around, so I didn't see anything particularly useful," Lu Yuan answered crisply.

"All I know is that there was a very unsettling aura emanating from this room at the time. Then I noticed that Frey was not in a good condition, so I pulled her out and gave her emergency treatment. After that, the ominous aura disappeared. As for what exactly happened, you can only ask Frey."

The Lantern Knight fell silent for a moment. He didn't think Lu Yuan was hiding anything. Moreover, everything in the room was still the same. Most importantly, the inscriptions here didn't seem to have been activated, which was very strange. How could Frey's condition at that time be explained?

If Frey weren't currently in a coma, the Lantern Knight would have even suspected that there was something wrong with the inscriptions here.

"Alright, you can leave now." The Lantern Knight gestured for Lu Yuan to leave, "Leave the matters here to me. We can discuss any further discoveries later."

Upon hearing this, Lu Yuan knew that the Knight of the Lantern was preparing to take him away first, but Lu Yuan understood, because the Knight of the Lantern's actions clearly showed that he did not want Lu Yuan to get involved in the research on the pathway mutation agent at this time.

Lu Yuan wasn't too concerned. Right now, he just wanted to figure out the plague potion first, and then get the Knight's Token.

Before leaving, the Lantern Knight shone his small lantern around Lu Yuan, and after confirming that he found nothing unusual, he let Lu Yuan go.

"Hey, Lu Yuan." Auden suddenly nudged Lu Yuan. "If you don't talk about the medicinal herbs now, when will you? Judging from Frey's condition, it'll probably be two or three days before she wakes up."

Oh, right, I almost forgot.

Lu Yuan turned around decisively.

"Knight with the Lantern, I need to request some medicinal herbs."

The Knight with the Lantern looked around the room on the right, then paused, turning back in surprise.

"Do you want to apply for medicinal herbs?"

"Yes, I need some medicinal herbs." After thinking for a moment, Lu Yuan briefly explained his thoughts to the Lantern Knight.

"I briefly looked at other people's ideas in the potion manual, and combined them with my own thoughts, I came up with some directions. The countermeasure against the plague potion is a long way off, but it has an incubation period, so I thought I would change my target. Instead of making an antidote, I would first do testing to see if I could make a potion to identify who was infected by the plague potion. With screening, I could identify the infected people in advance before the outbreak and isolate them. This way, I can do my best to suppress the spread."

The Lantern Knight's eyes lit up as he listened to Lu Yuan's line of thought, because the idea was indeed good. Having an idea was already quite good, and listening to Lu Yuan's plan meant that he had a concrete plan.

"Sure, I'm not afraid to use medicinal herbs, I'm just worried about not having any ideas. Alright, approved," said the Lantern Knight. "What kind of medicinal herbs do you want? Just tell me their names."

Lu Yuan didn't stand on ceremony with the Lantern Knight and immediately rattled off a long list of medicinal herbs, many of which were extras that Auden had asked him to list, totaling dozens of kinds, as well as several extremely rare minerals related to purification.

The Knight with the Lantern couldn't help but twitch at the corner of his eye as he listened to Lu Yuan's long list of words.

"You're really not being polite. With so many medicinal herbs, it would take at least two days to prepare them."

Lu Yuan smiled, thanked him, and then quickly left.

Now that I have obtained my own medicinal materials, the rest is no longer my concern. Once I successfully reverse engineer the plague potion, I can naturally join the research on reverse engineering the pathway mutation potion. In the meantime, the others will not stop their efforts, and judging from the current progress, they probably won't make any significant progress. I'll just consider this group of people paving the way and providing some ideas, since the master book is for everyone to use anyway.
