This time Shen Chengping retreat for more than 100 days, and it is also the longest time he has been in retreat, in order to understand the longevity recipe that he got back to Yangzhou before he realized it, to say that the top martial arts in this world, most of the things mentioned in the book of the Tang Dynasty are from Buddhism or Demon Gate, but this longevity recipe has an extremely important position, and Shuanglong has laid the foundation and started a legendary life by comprehending part of the mysteries of longevity.

Some time ago, Shen Chengping took Wanwan back to Yangzhou, nominally to go back to his hometown to see, in fact, it was to play the idea of longevity, and it was extremely smooth, he got the longevity recipe from Shi Long, who had just started the longevity formula, the book of longevity recipe was made of special materials, water and fire were invasive, and it was extremely difficult to imitate, after Shen Chengping started, he knew that the longevity recipe in his hand was genuine, so as soon as he came back from Yangzhou, he couldn't wait to retreat and prepare for cultivation.

The recipe itself is written in oracle bone inscriptions, so there are very few that can be understood, and even contemporary literary masters cannot guarantee that all the oracle bone inscriptions on the recipe will be translated correctly.

However, this problem is not unsolvable for Shen Chengping, as an old monster who has lived for several lifetimes, after Shen Chengping has read through all kinds of scriptures and histories, he naturally inevitably expands the scope of knowledge, coupled with various favorable conditions, his research on oracle bone inscriptions can be said to be unmatched in the world, coupled with his deep martial arts foundation, coupled with the seven pictures on the longevity formula, Shen Chengping finally understood the longevity formula.

"I didn't expect this longevity recipe to be the innate true qi that I cultivated at the beginning, first cultivated the innate five elements true qi, and then gathered the five elements to transform yin and yang, it really deserves to be the first treasure book of the Daomen, especially the introductory part, it is a step higher than the realm of my Wuxiang Mixed Yuan Sutra, and even faintly let me see the realm after the great master, if I really break through the great master, it is not difficult to break the void of this world, no wonder the legend has practiced this skill Guangchengzi has soared away......"

After reading it carefully, Shen Chengping couldn't help but want to try to cultivate, but there is another difficulty in cultivating this book, that is, the person who needs to cultivate has extremely high qualifications and understanding, and has not practiced martial arts, and does not have any true qi in his body.

After several reincarnations, Shen Chengping's Yuan Shen has also been tempered by the power of time and space several times, and the threshold of qualification and comprehension has become a void for Shen Chengping now, and the real difficulty lies in the true qi, but Shen Chengping still thought of a way, that is, to reverse the exercises, return to the basics, and turn his true qi into a rich vitality, with the help of the inner fist, these vitality will be directly dispersed into his own blood and bones, which can not only nourish himself, but also be able to cultivate his true qi more quickly again.

Thinking of this method, he carefully thought about it in his heart, and confirmed that there would be no problem, Shen Chengping spent a month of hard work, turning his true qi that was comparable to that of ordinary people for more than 30 years into vitality, and then used the inner fist to boil his own muscles and bones.

After that, Shen Chengping began the cultivation of the first Five Elements True Qi in the Wood Phase True Qi in accordance with the method of the introduction of the Immortal Formula.

The cultivation of the essence of longevity should be based on the true qi of the five elements, and after the foundation is stable, the true qi of the five elements will be used to transform the two qi of yin and yang, and the cultivation of the true qi of the five elements needs to choose one of them first, according to the characteristics of the transformation of the innate five elements, and finally practice the five elements, there is no hard rule in the recipe for immortality that you need to practice that kind of true qi first, but Shen Chengping knows that among the five elements, the most suitable choice is the water phase and the wood phase.

Although the relative power is not as good as the fire phase true qi bursting, nor is it as sharp as the metallographic true qi, it is the most suitable for getting started, and it is also more able to nourish the body, for this basic truth, Shen Chengping is still very clear, so after weighing it, he chose to cultivate the wood phase true qi first.

After making up his mind, Shen Chengping began to concentrate on cultivation, recalling the Immortal Secret Mental Method in his mind, slowly driving his own vitality in his body to run, Shen Chengping seemed to feel an indescribable touch, from the great and magical mystery of heaven and earth cultivation, and the multiplication of all living beings......

"Knock Knock Knock ......"

Inexplicably, bursts of heartbeat appeared in his mind, this is Shen Chengping's own heart beating, and at the same time he also felt a vibrant, vigorous and huge life force, this is Shen Chengping's own vitality, under his full attention, he didn't notice that his spirit was driving the vitality of the whole body, and the beating of his own heart began to resonate a little bit, and the spirit and body were unprecedentedly close together......

Generally, the true qi of martial arts practitioners is also fluctuating. Innate True Qi is a higher level and subtle fluctuation, because it can be combined with the human spirit. Shen Chengping clearly felt that the fluctuation of his own life energy, this fluctuation has a special law, revealing a pure charm, implying the fluctuation of his own cultivation of the Phaseless Mixed Yuan Sutra, creating yin and yang, ever-changing, moving in stillness, like a virtual and real, full of spirituality......

This wonderful state has given Shen Chengping a lot of insights, especially the perception of his own life aura is even more difficult to meet, Shen Chengping has practiced for several lifetimes, and this kind of perception is also the only time, which also allows Shen Chengping to take a big step forward in the integration of the Wuxiang Mixed Yuan Sutra, the inner family fist and the longevity formula, Shen Chengping believes that as long as he is given time, his newly created exercises will definitely be a higher level than the original Wuxiang Mixed Yuan Sutra.

When Shen Chengping turned back from this wonderful realization, he found that the true qi in his body was not the innate true qi of the wood phase that he had expected when he first cultivated, not even any of the five elements and yin and yang innate true qi, but a kind of mixed yuan ruyi, as if it could create ten thousand ends of the true qi, although he had not tried it, but he had an intuition in his heart, as long as he thought to himself, he could transform this true qi into any of the innate five elements or the yin and yang immortal secret true qi.

From this point, he can be said to have practiced the recipe for longevity, or it can be said that he has not practiced it, or now Shen Chengping has practiced a martial art formed by the combination of his own Phaseless Mixed Yuan Sutra and the Recipe for Longevity, this martial art is Shen Chengping's thoughtless under that wonderful perception, his own true qi is naturally formed, and it is formed according to the principle of heaven and earth, which is different from any martial arts that Shen Chengping has been exposed to before, but it seems to be able to see the shadow of all his previous martial arts.

"Martial arts are the same, there is no phase and formlessness, mixed yuan Ruyi, it is better to call it Ruyi Heart Sutra!" Shen Chengping said in his heart.
