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

Therefore, Lu Yuan was prepared to devote all his energy to the plague potion.

Lu Yuan turned to the section on plague potions in the general book. After reading it, he couldn't help but sigh that some of these people were indeed geniuses. Moreover, judging from the previously overturned plans, their research on plague potions had also reached a bottleneck.

First, since there are currently no infected people to use as subjects, they can only judge the potion's potential based on small-scale, limited experiments.

The following are the comments they left.

"This drug has a clear incubation period. There will be no signs of infection before the outbreak. The specific incubation period is yet to be determined. To prevent any accidents, the drug was given to the captured heretics. Four days have passed so far, and there have been no obvious complications. Since it is impossible to determine the extent of complications and transmission, it is recommended to continue isolation and increase testing methods. Currently, the following drugs have been used for testing, but all have failed."

Further down, a large number of medicinal herbs were listed separately, which saved Lu Yuan a lot of time. Auden even saw several herbs that he had originally wanted to use, but judging from the records in the booklet, it was clear that he had failed.

"They even proposed a theory for ore testing," Lu Yuan turned to the next page, "but it's still pending and under discussion."

This opened up a new avenue for Lu Yuan. He didn't necessarily have to use medicinal herbs. He could also try using the ores provided in the introduction. Many ores have significant fluctuations in their resistance to pollution, which might have unexpected effects.

Some even suggested borrowing a statue from the church, but this proposal was rejected for a simple reason: how could the church possibly lend you its own angel statue? Besides, the North is so vast and has so many people, how long would it take to detect them?

Lu Yuan and Auden felt both moved and gratified when they saw the discussion in the manual. Although some of their proposed solutions were indeed a bit unorthodox, after such discussions, some of them were actually feasible and could save Lu Yuan a lot of time.

The younger generation is truly formidable.

"Starting tomorrow night, we will officially begin developing this potion." After a brief discussion, Oden and Lu Yuan decided, "Tonight, I will synthesize this information and try to come up with a feasible method."

So we have to stop here for tonight. First, it's getting late, and second, we don't have enough medicinal herbs and ores. With these herbs, it's not enough for Oden to go all out. It seems we need to find Frey and ask if we need to report to her if we want more herbs, and then apply for them from the academy.

This is a great opportunity to get Knight's Tokens for free.

There was no one in the outer room. The lights in the rest area were on, the two sofas were empty, and there was no one in the reading corner. Frey was obviously still in the room on the right where the mutated potion was administered.

Lu Yuan was not allowed to enter that room for the time being, so he walked to the oval-shaped door on the right and knocked on it.

After a series of thumping sounds, no one responded.

Lu Yuan knocked again, but the room remained quiet, without making a sound.

Hmm? Is Frey not inside?

Just as Lu Yuan was wondering, gray-white text suddenly popped up at the edge of his vision.

[Environmental Sensing: Pollution source detected. Please be careful.]

[Environmental Sensing: High-level pollution source detected. Please move away immediately...]

Two gray and white text messages popped up in succession, and Lu Yuan's pupils shrank. Something bad had happened inside.

Lu Yuan quickly looked around, grabbed two bottles of holy water, holding the high-grade holy water in his hand, and then, without any hesitation, opened the door.

The scene inside the room left Lu Yuan completely stunned.

A somewhat distorted figure was swaying back and forth. It was Frey. She was standing in the center of the room, her body swaying slightly at an abnormal angle. Above her, in the air above the room, was a ghostly figure.

The illusory figure was indescribable, leaving no further traces and emitting no particular aura. It simply hung there, eerily quiet.

Even though Lu Yuan was standing right at the door, he wasn't affected at all. Only Frey seemed to be mesmerized, her expression a mixture of conflict and desire to get closer, her little face contorted in a grimace.

"What the hell is this place?"

Lu Yuan cursed under his breath, and the time signal on his chest was now activated.

"You can go forward," Oden's voice rang out at the same time. "That thing's aura hasn't fully dissipated yet, so be quick."

With a swift movement and the help of the timekeeping system, Lu Yuan brought the world to a gradual silence.

Lu Yuan did not examine the phantom closely, because if such a strange place was also a forbidden area, and he were to keep an eye on it, something unexpected might happen, and Frey might really be in trouble.

Time seemed to slow down before Lu Yuan's eyes. In just a moment, Lu Yuan grabbed Frey's wrist and dragged her out of the room.

It wasn't until he pulled Frey out that Lu Yuan realized that Frey's aura had changed. Her pathway seemed to be shifting in some unknown direction. However, the good news was that the transformation didn't seem to be progressing rapidly. Lu Yuan discovered it in time, and there was still hope for her.

Meanwhile, the white light outside, which had been quiet all along, suddenly lit up with a red warning light, clearly indicating that Frey's rationality was slipping away.

Lu Yuan knew that if he didn't do something soon, although Frey's pathways hadn't been transformed, her rationality would likely be seriously compromised.

"Never mind the rest," Oden said decisively, "Slap her twice first."

Lu Yuan didn't hold back either, and slapped Frey twice across the face. He didn't hold back at all, and Frey's face immediately became red and swollen.

Seeing that it wasn't working, Frey's eyes were still filled with confusion, and her body was still twitching slightly.

"Don't stop, hit harder."

Hearing this, Lu Yuan didn't hold back and slapped her several more times. This time, Frey seemed to finally regain some consciousness. Her eyes swayed as she struggled to see the situation in front of her.

"Good, she's regained some consciousness. Stop hitting her." Oden's voice was urgent. "Quickly prepare some purifying potion and give it to her. Oh, right, didn't you say you could see other people's conditions? Now's the perfect time to use it."

Lu Yuan focused his gaze on Frey.

[Target detected: Frey (Student of the North Campus of Knight Academy) (Extraordinary Knowledge Path) (Pathway in Transformation)]

[A human with considerable knowledge of potions, but her path seems to be veering in an unknown direction, and the effects of the transformation appear subtle. Perhaps there is still hope.]

Looking at the description in gray text, Lu Yuan wondered if there was still hope?

Without any hesitation, he focused his mind and activated another of his skills.

[Taboo Studies - Research Begins]

[Analyzing target status: Frey (losing her sanity) (pathway mutation in progress)]

[Status Analysis: Early stage of path alienation; the user's anchor point has not yet disappeared; rationality continues to fluctuate; still within a recoverable range.]

[The plan is being developed...]

The gray and white text flickered for a few seconds.

[Prognosis in progress: Take Hope Leaf (Optimal Version)]

[Principle: The Leaf of Hope contains a powerful will, capable of directly reaching the depths of reason and stabilizing its path and sanity.]

[Estimated success rate: 99%]

[Plan being generated: Take a sanity-stabilizing potion (safe version)]

[Principle: This sanity-stabilizing potion, made with high-level holy water, has a good therapeutic effect on current pathological mutations and loss of sanity.]

[Estimated success rate: 92%]
