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

But as the central figure, isn't anyone going to stop him?

Lu Yuan whispered his analysis to Auden, who fell silent after listening.

Because what Lu Yuan said is correct. Normally, no one would risk incurring public resentment and generating strange and polluting phenomena in their own empire while attacking other empires, unless they are abnormal.

If that's really the case, then there's no need to speculate, because abnormal people are capable of anything.

"However, regardless of the circumstances, these medicinal herbs you see are indeed extremely dangerous," Oden couldn't help but remark.

"If what you say is true, this potion that can bring plague is extremely terrifying. It could even corrupt a superhuman. Moreover, there's an ingredient in it that you can't even see clearly, which means it might be an even more terrifying ingredient, one that I don't even recognize. This is terrible."

Lu Yuan frowned slightly and tapped the paper with his fingertip.

"Oden, do you have a way to blindly create a formula that can somewhat suppress its effects, using only these three herbs plus another, even more terrifying one?"

Lu Yuan's meaning was clear: since the specific ratio and ingredients of the current medicine could not be obtained for the time being, based on the three known ingredients, it was possible to carry out preliminary prevention, and even if it could not prevent or treat the disease, it could at least alleviate the symptoms to some extent.

Oden thought about it carefully.

"There are indeed a few medicinal herbs, when combined in a simple ratio, that can provide some protection against the aforementioned medicine. The effect of this medicine is already very obvious: it creates plagues. However, I am not sure which specific type of plague it creates. Moreover, I have never seen the reaction caused by the combination of gray vine and plague-causing mushroom. The plagues I experienced in my time did not involve a medicine that combined these two ingredients."

Oden paused for a moment, then slowly uttered the names of the five medicinal herbs.

Of these five medicinal herbs, one was the Pure Grass that Lu Yuan had heard of in the Bounty Zone. The other four were completely unknown to Lu Yuan: Dawn Flower, Moon Dew Grass, Chalk Root, and Clear Plague Leaf. Judging from their names, they were all medicinal herbs related to purification and healing.

Lu Yuan watched as Auden uttered these names, then picked up a pen and wrote them down one by one on a piece of paper.

"The formula I gave you might not work," Auden continued. "But theoretically, melting these five herbs according to the proportions I gave you should indeed have a certain counteracting effect on the three herbs you mentioned. However, you'll have to experiment to see the specifics yourself. The proportions, the methods—everything will have to be figured out by yourself. I can't offer you any more help. Even if I called up the other guys from underground, they still couldn't help you, because this kind of plague simply didn't exist in our time."

"The plague medicine we can develop is actually made of putrefied grass and the flesh and blood of other plagues. Then, we contaminate it with local water sources and food to make it possible for the plague to spread."

"However, the stability of plague potions is extremely poor. Basically, they will die very quickly if placed in an outdoor environment. So, as far as I can remember, there is no plague potion that can cause effective killing. This is because the conditions for use are extremely harsh. So, apart from certain taboos, certain strange occurrences, and special environments, there is basically no possibility of a plague being artificially created. And how could you in this era encounter one? It shouldn't be like this."

Oden muttered to himself, his voice revealing a restless frustration that he couldn't understand.

Lu Yuan couldn't explain it either, but for now he could only try it. One thing was certain: once this medicine was touched, or once the disease started, the effects would be absolutely terrifying. At least from the black patches that appeared, it was clear that this thing couldn't even read gray and white characters, which was absolutely terrifying.

Lu Yuan looked at the five medicinal herbs in his hand, but did not immediately study them. He planned to take another look at the formula of the potion that could conceal one's aura, hoping to glean some information from it.

According to Frey, this potion is indeed remarkably effective, capable of directly blocking a certain screening ability used by the North.

As a border defense, the North naturally has its own way of filtering out contamination, yet it is completely able to block it out.

A potion that can shield itself from information about its own pathways, remain undetected, and not affect its ability to be released at any time is indeed very rare. Its concept may be somewhat similar to the kind of potion that Laurina mentioned before, which can directly deceive the supernatural, but overall it should be quite different.

Lu Yuan picked up the bottle of light gray medicine. This medicine was not particularly polluting, or rather, it did not have any obvious polluting properties.

As Lu Yuan focused his mind, the gray and white text gradually popped up.

Special potion detected: Door to the Dead Lands (Special Product)

[A special potion unearthed from the Desolate Lands, containing the aura of those lands, capable of concealing one's presence within it; perhaps it is the key to entering the Desolate Lands.]

As the gray text appeared, a series of medicinal herb names popped up again. The first one was also in a black block state, and the gray text could not be displayed, but the number of black blocks was less than that of the Desolate Land's Delusion.

The other ingredients are ████, Mist-Hidden Flower, Breath-Suppressing Fern, and Rot-Spotted Grass. These potions do not have obvious plague effects. Apart from Rot-Spotted Grass, the other potions are not tainted with plague, and they are completely focused on concealing their presence.

The key to entering the desolate land.

Lu Yuan stared at the line of small, gray characters, his brows furrowing slightly.

One bottle is responsible for spreading the plague, and the other for concealing their whereabouts.

It's pretty self-evident what this group is up to.

Lu Yuan sighed and put the two bottles of potion back in their original positions, closed the inscribed box, and the somewhat unsettling aura was once again sealed away by the inscription.

Oden, somewhat curious, asked, "What's in this bottle?"

Upon hearing this, Lu Yuan briefly explained the composition of the aura-concealing potion to Auden, including the black block that couldn't even be displayed in gray or white text.

"I'm not entirely sure about the specifics," Lu Yuan said, placing the booklet on his lap. "But one thing is certain: this thing is related to the Dead Land, and I can roughly figure out its principle. It involves directly immersing one's aura into the Dead Land to physically conceal one's aura."

"Wait a minute," Oden frowned upon hearing this, "You're sure this is a potion and not an alchemical artifact, that you can conceal your aura in one place? After all, I've never heard of anyone being able to hide their aura with just some potion. It's unheard of."

Lu Yuan wasn't sure either; he simply told Auden the names of the remaining few clearly identifiable medicinal herbs.

After listening, Oden remained silent for a long time.

"Very basic ingredients, all medicinal herbs used to conceal one's aura, plus the Rotten Grass, and another herb that's difficult to see," Auden said, emphasizing each word.

"Theoretically, it's impossible for these things to conceal their presence when mixed together. The Rotten Grass itself is related to plague, and something that causes a contamination reaction after consumption is somehow connected to a concealment potion? No, what's wrong with this world?"

Lu Yuan sensed the astonishment in Auden's tone; it seemed that the guy's worldview had been shaken.

"Never mind," Oden began to calm himself. "I've been dead for over a thousand years, and I don't even know the exact time. It's actually quite reasonable that some things I can't understand have appeared in this era."

Lu Yuan was also a bit confused. If it weren't for the gray text indicating that this thing was indeed a potion, Lu Yuan would definitely have mistaken it for an alchemical product. So it was obvious that the way this potion worked and took effect was completely different from how he understood potions to take effect.

However, it's not a big problem. Frey said that the potion has made initial progress, and he can refer to what others are thinking and doing.
