This is a historical sedimentation, a condensation of civilization, which cannot be compared with anything.

  Finally, Lu Feng arrived in front of the palace. The entire palace had no main entrance, and from the outside, all that could be seen was endless darkness, as if something was hiding inside, a ferocious beast that devoured lives. But Lu Feng did not hesitate at all, because that feeling still existed. He could clearly feel that there was no danger inside. At this time, Lu Feng had no other choice but to trust his own feelings.

  Gradually, Lu Feng's figure disappeared into the endless darkness...

  "What is this thing..."

  At first glance, the palace at the peak of the altar doesn't seem that massive, but only after entering it did Lu Feng realize his own shallowness. If this sacrificial space could use a nearly perfect world as its final destination, then how could the peak altar be so simple?

  Inside, it is indeed a space, but compared to the outside, it is obviously much smaller. This is not a world, but a space opened up by a super strong person with their own divine power. Legend has it that if it's a god king strong person, they can even open up a life planet with just a wave of their hand! Of course, this is just a legend.

  At this moment, Lu Feng entered such a space.

  Although this is not considered big, Lu Feng understood that this must be a space opened by a super strong being, and it is very likely that the fallen quasi-supreme being opened this space. Not for anything else, just because this space is extremely solid!

  As he walked on the road, Lu Feng saw countless things. They were strange and different from one another. However, these things had a common characteristic, that is, they were full of infinite vitality!

  Gradually, Lu Feng walked further and further away. Finally, he stopped in his tracks. In his eyes, a kind of excited light suddenly flashed.

  "It is said that in legend, the ancient civilization was most famous not because of how powerful they were, but because of their crystallization of civilization!"

  "They, the true essence of civilization is... Dan medicine..."

  Elixir! Among the ancient civilization unearthed by the Star, there is the art of alchemy, as well as the art of elixir refinement. However, among these things, the most precious is still the art of elixir refinement! Compared to the art of elixir refinement and the discovery of those ancient elixirs, so-called "equipment" doesn't count for anything.

  These were also discovered by Lu Feng from the Heavenly Web. It was only then that he knew that the true essence of ancient civilization was actually Dan medicine!

  In the current Federation, the existence of Dan medicine has almost become a rare product. In the Federation's pharmacy, generally only primary and intermediate medicines can be sold. To get high-level medicines, one must join those powerful forces to obtain them. As for legendary-level Dan medicine, it is likely that only core disciples of major families have the qualifications to use it after achieving great success or showing extraordinary potential.

  As for the most terrifying mythical medicine, it is an existence of endless terror. Such a thing would be treated as a treasure by any family, and in the entire federation, it has been several hundred years since it last appeared in the sight of ordinary people.

  In medicinal pills, there are four quality divisions: ordinary, precious, extreme and perfect. The main reason for this division is that it was originally based on the dan medicine!

  In other words, Dan medicine is also divided in this way. The only difference is that there are only two levels of quality division in Dan medicine, namely inferior and perfect Dan medicine. The level of inferior quality Dan medicine is equivalent to the top-quality medicinal herbs, and its effect is often several times better than that of medicinal herbs!

  Nowadays, the high-grade elixirs in the hands of the federal government and those big families are almost all found from ancient ruins. Legend has it that when the ancient formula star was first discovered, the federation obtained countless precious elixirs here, including even legendary elixirs.

  Of course, legends are just legends, and no one can believe them. Lu Feng used to just listen to them casually. But now it's different. Because he knows that those legends are true! Perhaps the countless elixirs were really discovered from this ancient planet. Because at this moment, the strange things around him seem... possible...

  It's ginseng!

  "Unbelievable! There are actually so many elixirs! This is terrifying..."

  In the Federation, a high-grade elixir is almost priceless, and it's impossible to buy one even with tens or hundreds of millions. As for perfect quality elixirs, they can be considered truly priceless. Generally speaking, such elixirs are dozens or even hundreds of times more expensive than low-quality ones!

  But now, what Lu Feng saw in front of him were absolutely elixirs! And in terms of quantity, it was almost...

  Innumerable...

  "These elixirs should all be low to mid-grade, I can feel the power contained within them doesn't seem to be very great. However, even so, this is still terrifying!"

  "If all of them were taken out and sold, the wealth obtained would absolutely not be inferior to that of any first-rate family..."

  Of course, Lu Feng was just thinking about it. After all, Dan medicine is not a medicinal potion, once obtained, who would take it out to auction?

  Thinking of the value of these elixirs, Lu Feng had originally intended to take them directly. But in the next moment, he stopped. Because Lu Feng finally understood two things.

  The first thing was the elixirs in front of him, which were really too many! Too many, just too many! He was only one person, how could he possibly carry out such a large number of elixirs? Even if they let him take them freely, he might be able to take away only a few hundred at most.

  And the second thing is the level of this place's elixir!

  He also remembered that in legend, the federal government had obtained high-grade elixirs from ancient planets! To know, even legendary-level ordinary medicines are used as units of hundreds of billions. As for the price of elixirs, if measured with money, I'm afraid there's no need to compete without trillions!

  But at present, even if he were to take away over a thousand such pellets, their value would probably not be worth one pellet of inferior quality legendary medicine. Moreover, Lu Feng had only just walked a short distance so far. There must definitely be even higher grade pellets behind him.

  So Lu Feng did not rashly collect it, he chose to continue advancing.

  All the way, Lu Feng saw was a surging tide of passion and boiling hot blood. Because he felt that he had walked into a kingdom of elixirs, a world entirely composed of elixirs!

  "I don't know, all the low-grade dan medicine found in the Federation's history combined wouldn't be as much as what's here..."

  There are too many elixirs here. As he delves deeper, almost everything in sight is an elixir! Moreover, the quality is constantly improving.

  Later on, Lu Feng found that the high-grade elixirs had already exceeded tens of thousands. And he was still far from reaching his destination!

  Time slowly passed by. As he saw more and more elixirs, Lu Feng also gradually became numb. After all, looking at so many elixirs for a long time, he was no longer excited.

  Finally, vaguely, Lu Feng finally walked to the end after all.

  In front of me, there is no longer a sea of elixirs. Instead, it is an ancient and simple great hall. It is the hall within the halls, the temple within the temples.

  He saw the hall within the halls and Lu Feng stopped in his tracks. A hint of excitement reappeared in his calm eyes once again.

  He knew he had finally arrived at the end!

  Here should be the most precious place of this altar, and it is also the last gathering place of the entire ancient Fang tribe civilization!

  Lu Feng quickened his pace, without any hesitation, and even forgot about the existence of danger, directly stepping into that hall within a hall...

  Looking at everything in front of him, Lu Feng took a deep breath of countless cold air. His heart began to beat violently. Because Lu Feng finally saw the last legacy of the Gu Fang tribe!

  The hall within the hall did not occupy any space, it was just as seen from the outside, only tens of thousands of square meters in size. The things inside were also not as numerous as those on the outside. However, even so, Lu Feng could not calm down. Because he knew that taking out anything from here would be equivalent to the total value of several thousand or even tens of thousands of elixirs on the outside!

  "These elixirs have absolutely surpassed the high-level grade! Could it be, could it be that these stone pedestals are all bearing legendary-grade elixirs?!"

  In front of him, there were thousands of small stone pedestals, and on each pedestal lay a different kind of elixir. From these, Lu Feng felt a powerful surge of energy. These were far beyond the elixirs outside, and even the high-grade ones couldn't compare to them.

  Apart from the thousands of small stone pedestals, there are also ten large stone pedestals in the center, and on top of them, ten dan medicines lie quietly. Apart from these, in the very center, there are three things similar to stone pedestals.

  Lu Feng looked at those ten stone pedestals, his heart beating constantly at this moment.

  "There are thousands of legendary-grade elixirs outside. But the stone pedestal in the center is clearly different from the others. So, those ten elixirs..."

  "Legendary!!"

  Here, there is actually a legendary pill!

  Thinking of this possibility, Lu Feng's heartbeat reached its limit. Although he didn't know the specific effect of the myth-level elixir, it didn't prevent him from knowing that a myth-level medicine existed!

  According to legend, the mythical medicine was named as such because it had an effect that was almost divine! The medicine is divided into two categories: cultivation and auxiliary. If a person with no innate talent whatsoever consumes a cultivation-type mythical medicine, they can become a perfect peak warrior in one go! Of course, unless it's a perfect-quality mythical medicine, the consumer's limit will be reached after taking it. Nevertheless, mythical medicines are still something that drives countless people crazy. After all, becoming a peak perfect warrior is the ultimate goal, the highest realm under the gods!
