"1.2 billion Divine Crystals per gram, so to make weapons effective against Night Demons, it would require more than 10 billion Divine Crystals."

"This price really isn't low."

"But judging by those videos just now, this kind of destructive power shouldn't be fake. If he truly wants to sell, he will definitely provide us with some strong evidence."

"Yes, didn't he say he would show us proof later? So let's wait and see."

"Hey, brother, the more you buy, the higher the discount. Should we place a group purchase order together, buying 1000 grams at once, and then divide it according to our needs? Saving a little is still something."

"That's what I was thinking too. I saw that chart earlier; if we purchase over 1 ton, the discount can reach 15%. We should try to gather some people."

"Count me in!"

"Me too!"

Although the items haven't officially started selling, many people already have plans to participate in the group purchase. Some even have the funds to buy extra and sell at a markup to earn a profit. If handled properly, there's a possibility of making money!

However, at this time, everyone's attention shifted from Krypton Gold to the last product.

Being able to heal wounds caused by Night Demon attacks is absolutely the most important thing for everyone!

"Everyone knows I have many side jobs, such as Artifact Refining formation, bridge screen pasting, fortune-telling star sign interpretation, beauty breast enhancement, a bit of everything, but my greatest strength is my Alchemy technique!"

After hearing this, many nodded, especially those who had conducted a thorough investigation of Zhang Menglong. They knew that during his time in Yanlan Empire, he had concocted some incredibly high-grade elixirs several times, even triggering lightning tribulations multiple times!

An alchemist who can trigger lightning tribulations is at least above Saint Grade; their elixirs are highly effective for most martial artists in the Divine Cultivation Realm.

Moreover, while in Skyless Realm, Zhang Menglong sold a batch of high-grade Saint Grade elixirs, some of which had unbeatable and priceless effects, which was enough to make every superpower fight fiercely.

Among the ten or so superpowers, there's one called Shennong Hall, where every martial artist possesses the talent of an alchemist. In other words, everyone in this faction is an alchemist! 𝐟𝕣𝕖𝐞𝐰𝕖𝚋𝐧𝗼𝚟𝐞𝕝.𝗰𝐨𝐦

In this place, several Elders personally said that if Zhang Menglong were willing to join Shennong Hall, he could become a Core Disciple without any examination!

So, when it comes to Zhang Menglong developing medicine that could heal Night Demon injuries, this might truly not be impossible.

"Now, let me introduce the last item of this product launch," Zhang Menglong opened the final few slides; it was a test tube resembling an oral solution, containing a green transparent liquid.

"Its name is Green Arrow Oral Solution. It can not only kill viruses left in the human body by Night Demons, preventing mutations, but also rapidly heal external wounds. Even if your arm is ripped off entirely by a Night Demon, using it will make you whole in one minute!"

"Is it really that powerful? Not only can it counteract Night Demon viruses, it can also help with limb regeneration?"

"I've heard of limb regeneration elixirs; they're Saint Grade five-grade pills, and their price is in the tens of billions of Divine Crystals."

"That wasn't exactly limb regeneration. That elixir seems to only reattach limbs that aren't completely necrotic; if the limb is missing, it can't regenerate."

"The Saint Grade Seven-tier Innate Reconstruction Elixir is the true limb regenerator, though its price is over a hundred billion Divine Crystals."

"If it's this expensive, how would we afford it?"

"Exactly, its additional value is too high!"

...

"Haha, everyone must be worried that this item would be pricey, right?" Zhang Menglong seemed to have heard the others' discussions. "In reality, its price isn't high. The reason is simple: its main ingredient comes from the Night Demons."

Zhang Menglong detailed further, "Everyone should be familiar with some detoxification drug principles, like Warcraft's beast toxin, injected into naturally resistant organisms to extract serum, and Night Demon antibodies work similarly."

Everyone nodded; this was basic knowledge. However, developing this serum antibody involved countless experiments, even capturing many indigenous creatures in this Ancient Cave Heaven, though no naturally antibody-carrying creatures had been found.

So, how did Zhang Menglong develop his antibody?

"No need to hide from everyone; I'm the natural antibody," Zhang Menglong said, "These antibodies were extracted from my body after infecting myself with Night Demon toxins, then artificially synthesized in large quantities!"

"Wow!" the scene was boiling.

This stuff was made from Zhang Menglong's body? Is he really not afraid of dying?

"Good grief, what a tough guy."

"Isn't he afraid of turning into one of those monsters?"

"Suddenly, I feel it's reasonable if the antibody is slightly more expensive."

"Yes, if it were me, I'd feel like I'm slighting myself if priced cheaply."

"I'll sure pay for it in tears!"

...

"Next, I'll announce its price," Zhang Menglong opened the final slide, "Not 9,998, or 998, but only 98 billion Divine Crystals to take this antibody home! It's effective when used within 1 minute after being injured, plus it provides a 10-day protection period!"

"Protection period? Does that mean even if bitten by Night Demons within the next ten days, you won't get infected?"

"This price works for me."

"That's equivalent to buying a life for 98 billion Divine Crystals."

"Even if I have to sell everything, I definitely want to get one!"

...

"Alright, all products have been introduced," Zhang Menglong closed the slides, "Next is the session I believe everyone has long awaited, yes, we're moving on to our product demonstration!"

"Boom!" Zhang Menglong waved his hand, and a massive container suddenly dropped from the sky, crashing heavily onto the central open field.

The container was truly enormous, over a hundred meters in both length and width. It's unclear what was used to transport it into the sky earlier.

"Boom!"

"Boom!"

Inside the container, there seemed to be something, constantly emitting a strong beating sound.

"What's in there?"

"Could it be a Night Demon?"

"Indeed, it's a Night Demon inside!" Zhang Menglong announced, "I've simulated external darkness environments, captured a Divine Breath six-grade level of Warcraft, and today, a lucky audience member will be the first to experience these products. Is anyone willing to take part voluntarily?"

"Lucky audience?"

"Lucky my foot; if those things were all a lie, wouldn't this person just become unlucky?"

"Exactly, he wants us to seek our doom, right?"

Listening to the fearful and cautious voices didn't surprise Zhang Menglong at all. After all, nobody wants to jeopardize their own life.

"Seems like no volunteers," Zhang Menglong smiled slightly, "If it were me, everyone wouldn't believe it, so someone else must do it."

"Therefore, today, I'll heavily employ an experimenter!"
