The causal aura in the mirage stone actually has no obvious meaning, it is only born with the beginning of the life of this stone.

The cause and effect of every thing can only be seen through everything in its life from birth to this moment, so this kind of causal breath is nothing more than a medicinal breath that purifies the negative energy of the chakras of the whole body, can eliminate karmic obstacles, promote cell renewal, and strengthen immunity.

Therefore, the mirage stone is also a kind of main medicine called Jingxin Pill, which is mainly used for counseling when the mind needs to be quiet, and is mostly used to comprehend the world first.

This kind of aspect is obviously more practical than this simple auxiliary pill because Li Zhi has a higher level of enlightenment pill.

Therefore, he attaches more importance to the innate spatial power in the mirage stone, which helps to leave this place, and can also perceive more spatial law aura through this kind of essence.

It is far more advanced than the aura of space rules in ordinary space stones, and at present, the people around him are the only ones who can absorb the slightest trace of space laws and understand it.

Moreover, there are a lot of mirage stones here, there are tens of thousands of them, in his opinion, refining the power of space in these mirage stones for his own use, maybe a few wisps of spatial law perception will be formed.

Two days have passed since I put away these precious mirage stones, and at this moment I retracted my mind and withdrew, but I saw that around the magnetic field, Sun Simiao and other five or six people were also meditating and practicing.

Sensing Li Zhi's appearance, Fu Chen said depressedly:

"You can also feel it here, the power of space here is obviously not something we can enjoy at the moment."

Sun Simiao opened his eyes and smiled: "We should also be content and get so many mutated elixirs!" ”

Li Zhi happily asked about this, only to learn that the previous spirit herbs were all genetically recombined or another new category after genetic mutation, which was a natural phenomenon of biological reproduction, but many of the original medicinal properties had been increased by at least ten times.

Of course, there will be some toxins that have been produced because of this, and they are no longer suitable for refining pills, but fortunately, those existences that have been abolished have been thrown, and a few people have actually mined nearly a hundred mutated elixirs.

Among them, there are still many cherished varieties, such as the Yiyun Branch, which is refined with the Yiyun Pill, which is suitable for the pill to improve cultivation in the short period.

It's just that those who have not reached the realm take it, not only will they waste part of the medicinal properties, but they will also have to bear the intense pain of the meridians swelling and even tearing.

Another example is Yin Ning Grass, the best medicine for refining Yin and Cold Pills, which can increase the medicinal properties of the pill by three points, and only the medicinal properties of the Yin and Cold contained in the millennium are the strongest, and the dozen or so plants that Sun Simiao has in his hands are this kind of elixir that is old enough.

Sun Simiao took out a jade box at this moment, which was a few feet tall emerald green spirit grass, oval leaves the size of a thumb, and more than a dozen fruits were fiery red, thin at the top and wide at the bottom, like red candles.

"It's called the Spirit Candle Fruit, it can't be transplanted, and the medicinal properties of the fruit are lost quickly after being picked, and it's the main material for refining and making chemical pills, and swallowing it raw can also improve cultivation. However, most people eat it uselessly, because those above the master realm no longer need it to create another creation, but it is very suitable for a few little guys to eat, including Wen Qi when he grows up! ”

"What kind of cultivation is there?" Li Zhi was obviously very interested in the Spirit Candle Fruit.

"Creation refers to creation and evolution, which is the function of nature's own development and reproduction, but in terms of medical Taoism, it is said that 'stealing means that the heart is in the middle of the void, and the five senses are treated, and the heart should belong to the earth; The lungs are covered with a canopy, covering the five organs, which should be fire; It should be created by heaven and earth. Therefore, when children take it, it is only a matter of individual differences to improve their cultivation, but more importantly, it can completely purify the use of the impurities of the spiritual root of cultivation, or it can condense the essence! ”

Li Zhi was overjoyed, he knew that the effect of this quenching spiritual root was far more important than simply cultivating and improving.

Moreover, his apprentices were originally the quality of the Twin Spirit Roots or Extremely Pure Spirit Roots after thousands of selections, and if they were blessed with the Spirit Candle Fruit, their cultivation qualifications would only become more perfect.

"However, Wen Qi should not take it until she is at least three years old, otherwise it will be difficult for her body to digest all the abnormal reactions caused by quenching!"

Li Zhi nodded, "Wen Qi also needs to be at that age to contact cultivation, I can understand this!" ”

Sun Simiao took out another thing, it was a red root plant that emitted a scorching breath: "This is called Huiyang True Grass, it should have been born in the molten flame, and after taking it, it fell into the illusion, but it is a strange thing that can prolong the life of ten years by decoction of one plant, and it does not need to be refined into a pill." ”

Immediately afterwards, what poisonous rune wood, demon grass, mending Tianzhi, Jinyangzhi, azure flower, etc., were all taken out and displayed by the old man one by one, and the smug look on his face was not concealed.

Yang Gaotang said with a smile: "The old man said that these mutated spirit herbs and medicinal herbs are unique in the world, and I am afraid that it is difficult to see them in other places, so he feels that it is more precious than the spiritual veins obtained!" ”

Sun Simiao also kept sighing in his mouth, Li Zhi led everyone back to the Chaoyuan Secret Realm, and after some discussion, he went to the alchemy room with Wen Qi in his arms.

Seeing Cheng Bi Lao Dao, who was refining flying swords, he handed him some mirage stones, and Lao Dao suddenly burst into laughter, almost frightening Wen Qi.

Cheng Bi then explained that with this mirage stone, he could perfectly solve his current shortcomings in refining flying swords, and this thing was sent at the right time.

Seeing that this state seemed to be in a drunken joy, Li Zhi shook his head and left there with a smile, he knew that if he didn't leave at this time, he would be kicked out.

In the next three days, Li Zhi conquered the fifth to eleventh layer of space one by one, but he rested for three full days because of this.

The reason is that in the eleventh layer of space, there is a half-demonized undead, and the fierce aura in the Chaos Sword is just its tonic, if it is not for the old dragon's timely reminder, I am afraid that even the entire sword will be devoured by it.

Therefore, Li Zhi spent several hours of fighting before he could burn his soul to the ground.

During this period, Li Zhi harvested three low-grade spiritual veins, one medium-grade spiritual vein, countless various materials and herbs, and even a main medicine Mengluo flower needed to cross the Erdan.

The Crossing Er Dan, as the name suggests, is a magical elixir that can be used to survive the disaster, and its main role is to use it to survive the tribulation, which is simply a life-saving straw for the peak of the late stage of the true view of the Tribulation Ascension, so it is imperative to obtain this pill.

It is actually a kind of energy pill that can instantly restore the peak of physical fitness, under the heavenly tribulation, any magic weapon to protect the body and when the energy in the body is exhausted, often a single Erdan can make the body cultivation as full as before.

However, it has a fatal hidden danger, that is, after the energy after taking it is exhausted again, it will cause the foundation of cultivation to crumble and be on the verge of collapse.

However, if you are lucky enough to survive the punishment of the Heavenly Tribulation, then the Heavenly Clouds will restore it, and you can instantly return the exhausted potential back to your body.

Therefore, if it is not a matter of life and death, no one will be stupid enough to take this pill, of course, its refining materials are also extremely rare, and often a cultivator realm powerhouse who is about to usher in the heavenly tribulation will do everything to prepare the next one as soon as possible.

Those scattered cultivators who failed to survive the tribulation were often due to the lack of a Doerdan, and they did not finally ascend to the immortal realm.

According to Yu Nan's memory obtained by Li Zhi, in the previous cultivation realm, in order to refine the Erdan, many people spent two or three hundred years just preparing the materials, but in the end, the refining failed.

This Du Erdan is already the pinnacle of high-grade elixir, and it is not an exaggeration to say that it is barely the level of an elixir.

Because this Crossing Erdan is an elixir that all cultivators who have reached the Tribulation Period want to get, but there are almost no cultivators who can refine Crossing Erdan.

First, the materials for crossing the Erdan are extremely difficult to find, and some of the materials are even extinct in the cultivation realm, otherwise how could there be the materials that have been prepared for two or three hundred years in order to cross the Erdan, and it can be seen how difficult these materials are to find.

For example, Li Zhi had found a large number of high-grade pills in the Cultivator Cave Mansion at the foot of Baiyun Mountain in Guangzhou, but there was no such pill.

Li Zhi, who had enough rest today, had made enough preparations when he entered the twelfth floor of the space, but he had made enough preparations beforehand.

On the twelfth floor of the cave, the entrance of the cave needs to bypass a section of stone wall, covered with green moss, wild penny and thatch, and on the top of the cave more than five feet high, a large green vine hangs down, covering the door of the cave.

When he walked into the cave, he immediately became cooler, and before he could reach the depths of the cave, he could see that the large and small holes inside were all shrouded in a faint layer of mist.

The reflection of the shadow rock wall presents a rather mysterious color, which makes people want to explore it more and more.

The stones in the labyrinth-like cave are also strange, and all kinds of strange stones are naturally piled up, twisting and turning, and eerie and terrifying.

There are many holes in the hole, the holes are connected, extend in all directions, look around the scenery in the hole, most of them are exquisitely shaped, especially the rock top is a big arch arc, as if it is a big pot lid falling from the sky, there is a special interest in it.

In the meantime, there is spring water, there is skylight, the stone pillars of different sizes, stalagmites are thousands, just like mushrooms after the rain, scattered and forested, especially a huge stone pillar that is more than ten meters high and goes straight to the sky, it is magnificent and beautiful, it is rare.

This underground cave is a wonderful underground world, it is quiet, elegant and deep, and the temperature in the cave is constant all year round, and the temperature is kept at the most suitable temperature.

The walls of the cave are covered with sediments of various forms, like beautifully carved reliefs, and the lights shine brightly, dazzling and magnificent.

Some places are unusually wide, others are unusually narrow, and the ceiling and walls of the cave made of limestone are smooth and flat, as if they were artificially made.

At the top of the deepest part of the cave, Li Zhi was surprised to find that there were many strange characters engraved on it, and the strange words were engraved on a large stone slab on the top of the cave.

Strange characters come in different shapes and sizes, there are hundreds, not in rows and rows, all of them are like ancient Sanskrit with strange shapes.

In the cave, you can also find many antiquities, including the daily necessities of ancient people, stone balls, stones sharpened into a triangle, and from time to time you can see the pedal depression carved on the cave wall.

There are small streams, natural bridges, tunnels and cloisters in the cave, but the sound is noisy, hot and humid, and it is also a colony for insects, snakes and bats.
