This is a group of attics located next to the forest and on the shore of the blue lake, deep and silent, very suitable for qi refining and retreat, and it is the residence prepared by the college for the top nine students of the top 900 in the past.

Xia Fan, as the joint second place in this junior martial arts competition, naturally owns one of the small buildings as his residence.

At this time, Xia Fan was sitting in the practice room of the small building, referring to the two ancient exercises he had obtained from the library building, perfecting the jade refining technique.

The jade refining technique practiced by Xia Fan has the effect of strengthening the physical body and condensing the true qi, and under the effect of the jade refining formula, Xia Fan can break through the third layer of qi refining and reach the intermediate realm of the fourth layer of qi refining.

However, the jade refining formula in Xia Fan's hand only had the first stage of cultivation, and he could only practice to the third level of qi refining, and when Xia Fan advanced to the fourth-level intermediate realm of qi refining, the jade refining technique was not enough for Xia Fan.

Therefore, Xia Fan had to improve the follow-up exercises of the Jade Refining Technique, and when Xia Fan saw the Five Elements Liuhe Fist, Xia Fan knew that he had found a way to improve it.

Although Xia Fan was in a scientific and technological society in his previous life, the nation to which Xia Fan belonged in his previous life has inherited a traditional martial art - national art since ancient times.

Xia Fan was just an ordinary office worker in his previous life, but the information in his previous life exploded, as a traditional martial art, although Xia Fan didn't know it, he still heard of it.

The national art uses skin refining, refining dirt, and refining the marrow to correspond to the bright energy, dark energy, and chemical energy.

Refining skin is refining fur muscles, and on the day of refining, it can have strong physical strength and explosive power, that is, Ming Jin.

This is very similar to the jade technique that Xia Fan has cultivated in this life, the same physical strength, and the same powerful strength.

And the refining of the internal organs in the national art is the refining of the five internal organs, and the day of refining, the dark energy is born.

Although Xia Fan didn't understand how to practice this dark energy, and what kind of strength the dark energy was, but thinking about it, the Five Elements Liuhe Fist should be able to give Xia Fan an answer.

And refining the marrow, judging from the words, should be the meaning of refining the bone marrow and generating the energy, however, there is no corresponding exercise reference, and Xia Fan does not understand the changes.

Looking at the jade refining recipe according to the theory of national arts, it is obvious that the first three layers of the jade refining recipe should correspond to Ming Jin and skin refining.

It's just that after Xia Fan practiced the jade refining technique in this life, the strength of his physical body was stronger than that of those masters of national arts in his previous life.

In his previous life, the explosive power of Ming Jin, a master of national arts, could reach hundreds of catties, which was already very powerful.

However, after Xia Fan now broke through the fourth layer of Qi refining by practicing the jade refining technique, his physical strength had reached tens of thousands of catties, and only in this way could Xia Fan Fang freely dance the thousand-pound cold iron giant axe.

Then, Xia Fan's next step is to improve the idea of refining the jade recipe and the follow-up exercises, which is to refine the internal organs, practice and strengthen the five internal organs, and cultivate the dark energy through the cultivation of the five internal organs and six internal organs.

This is also the reason why Xia Fan chose the Five Elements Liuhe Fist, after all, the remaining magic of the Five Elements Liuhe Fist just has the function of cultivating and strengthening the five internal organs, and after combining it with the jade refining technique, the exercises of the fourth to sixth layers of the second stage of the jade refining formula can be perfected.

·····

In the practice room, Xia Fan closed his eyes and meditated, and began his own practice, the second stage of the jade refining method has been established, and now Xia Fan is about to test its efficacy.

I saw that in the practice room, the aura of heaven and earth was permeated, surrounding Xia Fan's body, forming a vortex of spiritual energy, spinning endlessly, and countless spiritual qi of heaven and earth poured into Xia Fan's body one after another along the vortex.

With the influx of a large amount of heaven and earth aura, Xia Fan's skin and muscles did not have any reaction, and after Xia Fan advanced to the fourth layer of qi refining, the heaven and earth aura no longer had any effect on the muscles and skin on his body.

However, as the aura of heaven and earth is transferred to the internal route of the Five Elements and Liuhe Fist, various sensations such as soreness, numbness, swelling and pain arise spontaneously from the five internal organs in the body, which is like an ant biting and climbing on the internal organs, and it is like a sharp pain like cutting the heart and lungs. ...,
