Chapter 143: Wholesale Undying Divine Medicine?

"Then is it possible to sow them in a higher-level world, and then pull them back when they are about to mature?"

"It would be very complicated. In a higher-level world, the growth speed would be rapidly shortened, but after returning to a lower-level world, the growth time would be stretched out again. Calculating the interaction between them is quite complex and requires constant attention..."

The Chat Group has a huge pile of response rules, and Zhang Xuan finds the calculations between the growth speeds of different worlds a bit hard to understand; his head feels swollen just looking at them.

But he understands the meaning; simply put, his actions and plans are feasible.

At this, his eyes light up.

He prioritizes the world of *The Sovereign of All Worlds*, but after thinking about it, Zhang Xuan gives up on that idea.

There are simply too many people in the world of *The Sovereign of All Worlds* who can steal crops, and they can manipulate the Time River at the drop of a hat.

Relatively speaking, worlds like *Chang Sheng Jie* are much better, and *Divine Tomb* is even better.

"However, there is no rush for this; let's dig out this Undying Divine Medicine first."

The other four stones, which look like a rockery, are placed in front of Zhang Xuan. Zhang Xuan does not make any further plans and simply uses his hand to chop downwards.

In the blink of an eye, he splits two of them open; the insides are completely empty, with nothing at all.

And this blink of an eye has already consumed tens of thousands of catties of source stones. Although he had some expectations beforehand, when actually encountering such a thing, there is still a tiny ripple in his heart.

Fortunately, it is not his own money being spent, so Zhang Xuan does not have much of a concept of it.

"It's normal, after all, when Ye Fan was gambling on stones at the Dao Yi Sacred Land's Stone Workshop, he basically opened up everything of value. It's only natural that there is nothing left in the remaining stones."

When he chops the third one, it is vastly different from before. Just as he opens it halfway, a brilliant light suddenly gushes out from within.

A vigorous aura of life flows down from it. Just by taking a breath, Zhang Xuan feels his whole body relax. The realm that he had been working hard to suppress feels like it is about to become uncontrollable, as if it is going to rush directly to a higher level.

A block of Divine Source half the height of a person appears before him, the brilliant light so piercing that it makes it impossible to open one's eyes.

What attracts his attention even more is not the Divine Source block, but a pair of emerald green feet inside it. The feet are similar to a human's, but they have thin root hairs growing on them; it is clearly a medicinal herb.

At this moment, the corners of Zhang Xuan's mouth cannot help but curl up slightly.

Without needing anyone else to introduce it, Zhang Xuan has already recognized this Humanoid Undying Divine Medicine.

It is the Humanoid Undying Divine Medicine that legend says grew alongside the Great Emperor, but in the long passage of time, no one knows what kind of mishap occurred; its body was destroyed, leaving only the relevant root hairs.

For Sacred Lands and aristocratic families, an Undying Divine Medicine with only root hairs left would require a great price to make it grow, but for Zhang Xuan, it is not too much of a problem.

Zhang Xuan directly receives it into the Plantation, and sure enough, the Plantation sends a clear notification sound.

"Humanoid Undying Divine Medicine seed discovered, do you wish to plant it?"

"Plant it!"

"Maturation requires two years!"

Zhang Xuan's eyes light up; for him, this can be said to be the best news.

Under his control, the Undying Divine Medicine only needs two years to truly mature.

"It's a pity, if it could be even faster, that would be great!"

If he could harvest it every once in a while, he could slowly and leisurely buy over all the Ancient Saints and those top-tier powerhouses living in this world, without any worries at all.

After all, Longevity Medicine can allow these figures to live a second life. In the past, that was a treasure exclusive to the Great Emperor, and only the most top-tier figures were qualified to use it. Occasionally, when a Saint or a quasi-emperor could find one by chance and consume it to live a second life, it would be something that could be recorded in history books.

If Zhang Xuan could wholesale and use them in batches, that would simply be a tremendous thing.

"Hmm?"

Thinking of this, Zhang Xuan feels that he has vaguely grasped some kind of peculiar thread, but for a moment he cannot pin it down, so he falls into deep thought.

"Which link is the problem? I feel like these steps could be omitted."

Zhang Xuan rests his chin in his hand, and after thinking for a moment, his eyes suddenly light up.

"What is the most critical thing in the Zhetian World? It is that the environment of heaven and earth has changed drastically, making it difficult to give birth to enough powerhouses, and at the same time, everyone's lifespan is severely limited, making it difficult to obtain an immortal lifespan."

"Therefore, Medicine Kings and Undying Divine Medicine that can allow people to live a second life are sought after. But is the most critical thing the Medicine King and the Undying Divine Medicine?"

"No, it's not. The most critical thing is that kind of Immortal Substance."

The Immortal Domain, which is separated from the Zhetian World by a layer of World Barrier, is one of the fragments left behind after the Immortal Realm shattered back then.

It contains abundant Immortal Substance. A Great Power who has reached the Immortal Second Realm can obtain a near-immortal lifespan within it, easily living for millions of years.

Therefore, the most critical and precious thing in the Zhetian Universe is not the Longevity Medicine; even the Longevity Medicine can only allow a Great Emperor to live for another ten thousand years.

What is truly special is that kind of abundant Immortal Substance.

"I am quite lacking in Longevity Medicine, but as for Immortal Substance, I am not very short of it..."

Thinking of this, Zhang Xuan's eyes become increasingly bright.

He cannot help but think of when he refined the Dragon Inner Core that Chen Nan gave him; the vigorous Immortal Substance almost caused him to change from a young state into an infant.

And later, after going to *Chang Sheng Jie*, he also carried vigorous Immortal Substance on his body. Now, Zhang Xuan does not even know exactly how long he can live, but it is definitely longer than anyone else in the Zhetian World.

Even in terms of lifespan alone, Zhang Xuan feels that he might live longer than the Great Saint Body and the Great Emperors.

Is Zhang Xuan awesome in this regard? No, it is the other worlds that are awesome; it is the Immortal Substance contained within different worlds that is awesome.

"Even for Longevity Medicine, such a special substance can only be consumed by a person once; if the time is longer, it will have no effect. But Immortal Substance can be used for a long time, allowing people to keep living."

"If I could use some unique item to collect a portion of Immortal Substance from other worlds and bring it to this world, could it be used directly as Undying Divine Medicine, or even be more special and powerful than Undying Divine Medicine?"

Zhang Xuan's eyes light up all of a sudden; he feels that this matter is completely operable, and it is not difficult to do.

For worlds like *Chen Nan*'s and *Chang Sheng Jie*, the Immortal Substance is simply too abundant, abundant to an unimaginable degree. After all, any figure in such worlds can live for a long, long time.

If one were to casually pick some spiritual herbs or plants from their worlds, the contained Immortal Substance would be terrifyingly abundant—at least for the figures in the Zhetian World, it would be unimaginably abundant, easily allowing those ancient figures to obtain even longer and more enduring lifespans.

Casually putting the Divine Source that no longer contains the Humanoid Undying Divine Medicine into his Wheel Sea, Zhang Xuan sits cross-legged on the pavilion floating in the sky, silently contemplating the feasibility of the matter.

"For the many figures in this world, the Immortal Substance I possess is nearly infinite, inexhaustible, and never-ending."

"I can use Immortal Substance to buy over anyone I want to buy over, whether it is Gai Jiuyou, who could not live for nine thousand years due to the existence of Qingdi's Dao, or the Old Madman, or those figures who have also lived for a long time and want to obtain a longer life in this Shencheng, constantly digging for divine medicine and Medicine Kings from source stones—I can easily buy them over."

"If I wanted to, using Immortal Substance to buy over all the Ancient Emperors and Great Emperors in the Forbidden Zones would be very easy to do..."

Of course, Zhang Xuan knows that the last part is completely a dream, a flight of fancy.

Once the Ancient Emperors and Great Emperors in the Forbidden Zones know that Zhang Xuan possesses infinite Immortal Substance, they would definitely move against Zhang Xuan immediately.

With their temperament, it is fundamentally impossible for them to cooperate with Zhang Xuan; at the very least, if Zhang Xuan were to go and introduce this situation himself, he would only be sealed up by the Ancient Emperors and Heavenly Venerables in the Forbidden Zones, then treated as a blood cow to be continuously drained.

Unless one day Zhang Xuan can become a Great Emperor and then have the qualifications to communicate with them, otherwise, it is entirely wishful thinking; after all, the Ancient Emperors and Heavenly Venerables in the Forbidden Zones have long since extinguished their humanity over the long passage of time.

In the words of the Black Emperor, the true Great Emperors have long since died.

What exists in the Forbidden Zones is merely a group of terrifying figures whose temperaments have become twisted over the long years; one can only call them Supreme, they are not worthy of being called Ancient Emperors and Heavenly Venerables.

Zhang Xuan does not dare to trade with them for the time being.

"Not only can I not trade with them in the early stages, but even the information that I possess extremely abundant Immortal Substance cannot be leaked out."

"To use Immortal Substance to win people over, I must find other excuses."

Zhang Xuan pondered to himself and carefully weighed the problems involved.

Fortunately, he has a rich amount of reading and has an understanding of the various peculiar situations within the Zhetian World.

After thinking for a while, he took out a bottle of pills from his bosom that came from Chang Sheng Jie; those were pills used for daily cultivation.

For the current Zhang Xuan, swallowing a whole bottle would not increase his cultivation by much, but the Immortal Substance incidentally contained within these pills is quite dense.

Having stayed in Beidou for a period of time, Zhang Xuan already has a certain understanding of the scarcity of Heaven and Earth Essence in Beidou, and his grasp of lifespan is also much more precise than before.

"Taking one pill can probably increase one's lifespan by a year; for figures in Chang Sheng Jie, this bit of Immortal Substance is basically as good as nothing, after all, this effect is entirely incidental."

In Chang Sheng Jie, such an effect is not of much use, but in the Zhetian World, a pill that can extend one's lifespan by a year—and one that extends it by a year regardless of how long you have lived—is very, very special.

Those figures who can live for two or three hundred years taking one pill to extend their lifespan by a year, they don't feel it counts for much; after all, many Small Medicine Kings can extend one's lifespan by two or three hundred years, so a pill that can only extend one's lifespan by a year is not considered anything too special.

But for those Great Emperors who have consumed Longevity Medicine, extending their lifespan by a year is very special and terrifying.

However, Zhang Xuan is not entirely certain about the relevant medicinal properties, because he once stayed in Chang Sheng Jie for a long time, and the Immortal Substance in his body is too abundant; he does not even know exactly how long he can live, so it is hard to say clearly when evaluating these.

After thinking about it, Zhang Xuan went directly next door.

In a palace also suspended in the firmament, five-colored divine light was flickering and chaos was surging; that was Kongque Wang cultivating.

Sensing Zhang Xuan coming, the chaotic light around Kongque Wang surged and then returned to one, revealing his appearance as a youth of only five or six years old.

"Senior, why have you come in the middle of the night? Is it to open the source stone brought back from the Stone Workshop?"

"No, there are some things I need you to help me verify together."

Zhang Xuan did not hide it; he took a pill directly from his bosom and said: "This was my trophy from back then, an item similar to the Nine-Turn Immortal Pill that can extend lifespan, but my lifespan is currently abundant, so it is difficult to determine exactly how good its efficacy is, therefore I want you to appraise it."

Kongque Wang was startled, and then he was overjoyed.

Zhang Xuan's seniority among the Demon Race is frighteningly high; he claims to be of the same generation as the Demon Emperor, but he has never used this special seniority to demand the Demon Race do anything for him; everything is often an equal exchange.

Although Zhang Xuan seems to have never said it, for anything the Demon Race does for him, he responds with equal or even more abundant rewards.

He followed Zhang Xuan to the Holy City precisely with the intention of trading fairly with Zhang Xuan.

And during the day, he spent hundreds of thousands of jin of source for Zhang Xuan without even frowning, and now the reward has come directly.

"To be comparable to the Nine-Turn Immortal Pill, such a precious item, I fear I am not qualified to consume it."

Although Kongque Wang was very tempted in his heart, and even wished he could swallow the pill in one gulp—after all, having lived for nearly two thousand years, his lifespan is already coming to an end, and a pill that can extend lifespan is a supreme treasure to him.

Zhang Xuan actually organized quite a lot of language, wanting to paint a picture of a moving past so that the origin of the Nine-Turn Immortal Pill in his hand would not seem so suspicious.

As a result, he did not expect that Kongque Wang would agree directly after hearing it, without even a hint of doubt, which made Zhang Xuan pause for a moment.

Fortunately, he often chats and jokes with various members in the Chat Group, especially having the experience of having fooled Taishang Laojun and Dugu Baitian before, so he was quite calm at this moment.

His expression did not change at all; he just said lightly: "It is only similar to the Nine-Turn Immortal Pill, it is still far inferior; by my estimation, it can only keep a person in their peak state for one to two years, it is not too precious."

Hearing this, Kongque Wang breathed a sigh of relief, while also feeling a bit regretful, and only then did he take the pill from Zhang Xuan's hand.

He examined it carefully and found that this pill was plain and unremarkable, the spiritual light contained within was not dense, and it was basically useless for cultivation.

But there was a peculiar Immortal Substance contained within it; what was even more peculiar was that Kongque Wang has lived for two thousand years and could be said to have seen all kinds of spiritual medicines in Beidou, even having had contact with the legendary Undying Divine Medicine, but he could not distinguish what kind of spiritual medicine this pill in his hand was refined from, even after sniffing it carefully.

After a brief look, his innate divine ability did not allow him to distinguish any poisonous substances, and he did not think much more, tilting his head back and swallowing it into his abdomen.

Then, in an instant, a look of surprise appeared on his face.
