Looking at the jade disc of yin and yang, it introduces a kind of truth. In fact, this is a similar article to the exercises, but it is not summarized into a cultivation method similar to the Yin and Yang Jue that can be practiced directly, just an article.

The content of this essay is not long, only less than 800 words, which is shorter than the average college entrance examination essay. However, the content of the article comes from ancient Chinese in ancient times, which is a bit awkward to read, and the meaning and shape of the characters are quite different from modern Chinese, making it very difficult to understand.

Fortunately, when he accepted the inheritance of the Jade Saucer, the Jade Disc instilled the detailed meaning of this article directly into his mind, so there would be no ambiguity.

The principles presented in this article are somewhat similar to the Taoist theory of yin and yang balance, and it is not difficult for him to accept them. The article uses a large number of examples, quite in the style of the Zhuangzi. During this period of time, Tian Xu has repeatedly studied and scrutinized the book "Zhuangzi", and he has a lot of experience. At this time, when I read this "Yin and Yang Symbiosis", I felt very close. It's just that he didn't have any new insights for a while, so he put this article aside first.

The content of the last jade disc was "Space Compression", he originally thought it was a powerful technique to control space, but he didn't expect it to be a history book. In this book, it tells about the mythological period of antiquity, the process of brutal war between human cultivators and powerful alien invaders, and the process of the formation of the current solar system.

Outside the solar system, there is a lot of folded space and advanced civilizations. The corner of the universe that we observe is only a small part of the equation that is far from the truth. The starry sky we see is a scene that has been reflected by many spatial foldings, which is completely different from the actual outside space.

The earth was originally a breeding ground of an advanced civilization, and dinosaurs were the main species cultivated here. Humans, on the other hand, were prisoners of war, or sinners, in wars between higher civilizations, who were stripped of their fairy roots and relegated here as herdsmen who domesticated dinosaurs.

Those creatures of advanced civilizations, in legends, are called immortals or gods, and with a single thought, they can move mountains and reclaim seas, create or destroy planets.

After losing the immortal root, human beings cannot be like the high-level creatures in the immortal realm, they are born with an immortal body and can immediately start high-level cultivation. People can only start from low-level mortal bodies, and first find ways to cultivate mortal bodies, until the golden pill is consummated and ascended to the immortal realm, and then they can obtain the same cultivation qualifications as newborn babies in the immortal realm.

Although they lost their transcendent abilities, the ancestors of human beings, those prisoners of war who were stripped of their immortal roots, did not give up hope, and continued to explore from generation to generation, accumulating and summarizing various techniques for cultivating the truth to fight against the immortal world. broke out one after another heroic stories that have been passed down through the ages.

Tens of millions of years ago, Pangu killed the guardian of the fairy world, opened the sky with an axe, and killed the fairy world into a river of blood. Later, the war spread to the earth, Hou Yi, Nuwa, Gonggong and others led the human cultivators to resist fiercely, the immortal realm cultivators suffered heavy losses, and almost all the human cultivators died in battle, and finally the nephew exhausted all his strength to bring the earth into the folding space, avoiding the pursuit of the immortal world, Nuwa gave up her life to repair the destroyed heavenly dome, completely closed the entrance and exit of the folding space, so that the immortal world could not find the entrance to this space, protected human beings for tens of thousands of years, and allowed human civilization to continue.

This folded space that allows human beings to avoid the pursuit of the fairy world and thrive is the current solar system. However, although it has avoided the pursuit of the immortal world, it has also cut off contact with the outside world, resulting in the continuous loss of spiritual energy and cannot be replenished.

The earth's aura is getting thinner and thinner, and the realm that human cultivators can reach is getting lower and lower. If this situation cannot be changed and the spatial isolation is broken, human beings will eventually be annihilated in this folded space.

At the beginning of Nuwa's mending the heavens, the great powers among human cultivators emerged one after another, and although the immortal realm could not find the entrance to the space, it could remotely create demonic beasts and monsters comparable to the strength of human cultivators on the earth through a means similar to antimatter images, causing trouble for humans, and at the same time trying to perceive the direction of the folded space through these demonic beasts and monsters.

Limited by the principle of this technique, the strength of these demonic beasts and monsters will not be higher than that of humans, and the immortal realm will also be able to know the approximate strength of human cultivators. In the past few thousand years, there have been fewer and fewer demonic beasts and monsters, and the fairy world has gradually lost interest in continuing to hunt down humans. This also shows from the side that human cultivators have gradually embarked on a dead end.

The history of human beings and the immortal world is too heavy, and after Tian Xu read this text, he was deeply shocked. Although he had been exposed to too many things that he could not understand with worldly concepts since he entered the cultivation realm, he still couldn't bear such a heavy topic for a while, and a deep sense of powerlessness enveloped him.

After thinking for a while, Tian Xu put this heavy question aside, he is just a small Ning Dan monk now, and he has just Ning Dan, it is too early to think about this, let's go back and think about the problem of alchemy.

After reading "Common Sense of Alchemy", Tian Xu initially figured out that the so-called alchemy is actually a special technique to highly condense and compress the spiritual energy, and then use a certain formation to lock it up to facilitate the cultivation to absorb and utilize.

The source of the aura in the elixir can come from the elixir, or it can come from the surrounding air and environment. If you only obtain the spiritual energy from the elixir, then you need a large amount of elixir to refine enough elixir, and this process of alchemy only facilitates the absorption of the spiritual energy in the elixir. Judging from the current output of elixirs on the earth, it is simply not able to meet the needs of the cultivation world.

Another way is to use the elixir as a guide to gather the aura in the environment and condense it into an elixir. This approach is obviously more effective than the former, but it is also much more difficult.

Tian Xu took out the pills he bought from the cultivation bazaar and studied them carefully, and when he probed the aura into the pills, he found that there was an extremely pure aura inside these pills. These auras were tightly compressed together, and they were quite similar to the Jin Dan he condensed, recalling what Yin Yang Ding said at the beginning, he needed Ning Dan before he could refine the Dan, and the reason for it was estimated that it was here.

These spiritual qi were tightly compressed together, but there was no leakage, which should be the result of the suppression of the formation located on the outer layer of the elixir. Moreover, these formations are different, which is probably the reason why the pills have different effects. He can be said to know nothing about the formation, and it seems that he will definitely not be able to figure out the principle of this alchemy in a short period of time.

There are obvious differences in the content of aura in different grades of elixirs, and different types of elixirs have different techniques for locking and unlocking the formations that suppress aura.

"If you want to become an alchemist, do you have to learn to be proficient in the formation first?" Tian Xu asked secretly. If this is the case, then the road to learning alchemy is still quite long.

But he thought about it for a while: "Could it be that those alchemists in Shennongmen are proficient in formations? No, definitely not, if a person wants to be proficient in formations, he needs at least a lot of learning, and he needs to grow slowly for a long time, so that there will be no young alchemists." Moreover, there are only four condensing pills in Shennongmen, and one of the elders has not heard from him for many years, and then he was killed by Aunt Xu, Hao Qi, could it be that Aunt Zhou, as the master of the sect, wants to sit at home and refine the pill every day to supply the needs of other sects to buy?"
