Lu Zhen slowly withdrew the trace of aura that was visiting the dantian in Pang Mai's body, and a smile appeared on his face.

"Not bad." He said.

There are many people who can induce qi into the body in a day or two, and some people have psychic physiques, and they can absorb spiritual qi within an hour according to the method of cultivation.

However, although any of the four yin and yang qi to be absorbed by the Qi cultivation method can be regarded as successfully inducing qi into the body, it can be completed and balanced within two days, which shows that Pang Maimai already has a considerable understanding of the origin of this exercise, which is not easy.

"You just need to continue cultivating like this." He said, "When you come back in three days, you can learn all kinds of refining ingredients." ”

Pang Maimai went back to practice according to his words, and the more he practiced, the more he felt that this seemingly simple exercise was profound and profound.

She thinks that this is the charm of cultivation, an ordinary exercise that is not looked at by most people, but it has become so mysterious, I don't know how other exercises should be unfathomable!

And what she doesn't know is that "Yang Qi Jue" itself is an ancient exercise, to put it mildly, it should be regarded as a very high-grade exercise, and the reason why it is now regarded as a big road commodity by outer disciples is for a reason.

It can only cultivate for four hours a day to absorb spiritual energy, and it is in the early morning, noon, dusk, and midnight four time periods, not to mention the low efficiency, and it is difficult to persist.

It is already very difficult to achieve a balance between the four qi of Shaoyang, Laoyang, Shaoyin and Laoyin, let alone further fusion, and only obtaining one or a few of them cannot be balanced, and cannot make them circulate endlessly, and the spiritual power of this exercise will hardly have any bright spots to speak of.

And when it can circulate endlessly, it is easy to enter the realm of self-generated aura, so if it is cultivated well, it is actually very easy to enter the Qi Transformation Period, and it is also of great benefit to the cultivation of the foundation.

It's just that there are very few people who can do it!

In addition, one of the reasons why "Yang Qi Jue" is not valued by people is that its spiritual power has no attributes, although the spiritual power without attributes can be used and practiced by any kind of spiritual root, but there is no attribute bonus, and those who regard it as the main exercise will have a worse attack efficiency. This is indeed the shortcoming of the very subtle "Recipe for Raising Qi".

But in any case, this is a profound practice that non-sages can't create, and it can be called a great complexity.

And Pang Maimai grasped the most critical core of this exercise at the beginning, that is, the two transformation processes of old yang at least yin and old yin at least yang, she felt that this was very magical, and it was also the reason why yin and yang aura could be converted into each other.

She even thought of heaven and earth.

At the turn of the dry season and the rainy season in Africa, the ponds dried up, the crocodiles hid in the mud to save their last breath, the bones everywhere were steaming, and finally the first rain arrived, and the animals that survived were celebrating in the rain.

The dark Middle Ages, the obscurantism ruled by religion, the sudden start of the Renaissance, those sculptures full of vitality and the renewed emphasis on science, are they considered to be old yin and young yang?

Not to mention the withering of flowers after blooming to the extreme, don't say that the golden crow rises and the jade rabbit sinks, don't say that winter goes to spring, and summer ends with autumn.

Let's put it more bluntly, for example, a man who is rough on the outside and acts as heroically as Qiao Feng, but he has such tenderness in his heart, is it considered old yang or at least yin?

For example, some men with beautiful appearances but sharp appearances, can they be regarded as old yin and young yang?

Pang Maimai didn't know that her comprehension of these truths had enabled her to grasp the core of the Qi cultivation technique, and the four qi she absorbed were very balanced, so that in just a few days, the aura in her body had spontaneously begun to slowly rotate and slowly transform on its own.

This is equivalent to saying that she has touched the edge of the Qi Transformation Period!

Of course, it's not that she will be able to enter the Qi Transformation Stage soon, she still needs a long time to use her spiritual power to wash her muscles and veins, and open up all the tendons, which will take time. But after opening up in the future, she can quickly enter the Qi Transformation Period, without realizing the law of circulation and the bottleneck of spiritual energy self-generation, you must know that opening up the muscles and veins of the whole body is one thing that anyone who practices any exercise can do with hard work, and understanding the law of circulation and making the spiritual energy in her body can circulate and generate itself is the key to the promotion of most Qi Induction Period cultivators.

Inner disciples who have the guidance of a good master, have talents, and have excellent exercises can generally enter the Qi Transformation Period, but the outer disciples who can enter the Qi Transformation Stage from the Qi Induction Period are not one out of ten.

Most of the outer disciples were limited to the Qi Induction Period for the rest of their lives, and they could use small spells and passed away between the ages of one hundred and fifty and two hundred.

And because her aura has been able to circulate and transform spontaneously, she can better absorb and use her aura, and the amount of aura is naturally larger than others, and her foundation is stronger than others.

What's more, she only needs to cultivate for four hours a day, compared to those who are diligent and hardworking, and who cultivate in addition to eating and sleeping a day, she still has a lot of time to cultivate for other things.

Not to mention anything else, her main professional refining weapon is quite time-consuming!

After Lu Zhen expressed his satisfaction with her mental cultivation, Pang Maimai entered the stage of refining the basic learning.

After all, Lu Zhen has a lot of things to do, and time is precious, so this time the task of teaching Pang Maimai to understand the refining materials was handed over to the second apprentice, You Hao. You Hao himself was also going to refine the weapon, but he was caught by the master, and he taught the little junior sister with a bitter face.

To say that this is really a tedious task, there are really a lot of things in Lu Zhen's private library, not to mention tens of thousands, there are thousands of kinds.

You Hao complained bitterly, but he also taught with all his heart.

Pang Maimai studied very seriously, she took notes, and would sort it out by herself later, You Hao would tell her one thing when she touched it, but she would set up an outline by herself, what things belonged to which category, and when she came into contact with new such items in the future, she would add new ones to this category.

She will ask very clearly about the peculiarities of each thing, the do's and don'ts, the handling of materials and the preservation of materials.

"Can the purple cloud sand be in the same furnace as the ebony wood?"

"Yes." You Hao was extremely tired. He originally thought that he only needed to teach this little junior sister who had just started to learn a little basic thing, but when he first started, he was not impatient with such boring learning, he would rather follow the master and learn slowly in the process.

This little junior sister is so tireless!

Fortunately, the little junior sister is talented and intelligent, and she doesn't need him to repeat everything a second time, but she has to dig deep into everything, what can't be compatible with what, what is the bonus with what, what is the way to collect, and how to preserve it properly......

You Hao felt that he had been hollowed out!

"The rhizome of the Ryuze Lingmu needs to be buried in the jade sand and then preserved in a box made of thousand-year-old red dragon wood?"

"Yes."

"The green dragon bone must be taken out before the green dragon dies to be of the highest grade?"

"Hmm." You Hao was weak and replied mechanically.

"It's cruel." Pang Maimai put down the jade-like bone with a faint cyan texture in his hand.

You Hao and his junior sister's teaching behavior lasted for more than two months and nearly three months, and finally came to an end.

"Master, Senior Sister is now familiar with all the materials in your private library." Finally ended the mission, and You Hao, who was about to burst into tears, finally stood in front of the master with his chest up.

"Remember it all?" Lu Zhen was a little surprised.

You Hao didn't hesitate, he felt that the students he taught were at least excellent or very good: "No problem, senior sister she ......" After thinking about it, he said, "It's quite talented." ”

The graduation report of the course of Pang Maimai's refining material foundation study is a volume of notes that are quite thick and the handwriting is quite beautiful.

Lu Zhen opened it and saw that these raw materials were divided into four categories: animals, plants, minerals and others, and there were subdivisions under each one, such as plants are divided according to the place of origin, and animals are divided according to aquatic, ground and flight...... In each category, it is arranged in a very orderly manner from low to high, and each material is also equipped with details such as do'o, acquisition, and preservation, and the places that are not understood are specially marked with cinnabar pens.

He was stunned.

The next day, Pang Maimai got a reply from the master, he read the notebook carefully, and answered all the questions, occasionally wrong or incomplete and accurate places he modified and supplemented in detail, looking at the notes densely written with Zijin grass juice meticulous small characters, Pang Maimai was very moved.

I really have a good master!

And Lu Zhen was in his inner room, and he also sighed at the candlelight: his newly accepted disciples are really extraordinary, and the notes he makes can be written in a book.

Let's just compile it on this basis, and leave it to the promising descendants of the sect, which is also a good thing.

The name is, well, "Introduction to Refining Materials".

Lu Zhen naturally didn't know that this book had really become a highly praised refining material book in the entire cultivation world in later generations, and everyone praised it as "well-organized and extremely detailed".
