From the next day, Yu Tianlai lived a Robinsonian life on the island.

He first made a thorough survey of the entire island, and determined that there was not a single human on the island except him. And although this isolated island is small, it is quite rich in products: there are small animals in the mountains and forests that are stupid and not afraid of people, there are many kinds of fish and shrimp in the lakes and streams, there are many kinds of wild fruits and vegetables that can be eaten, some natural salt grains can be collected in the rock crevices by the sea, and there are endless seafood ingredients in the sea...... Under normal circumstances, as long as a person is not too lazy, he does not have to worry about food and clothing at all.

What's more, Yu Tianlai's physical fitness far exceeds that of normal humans, and he has rich experience in two lives in the wild, and the most important thing is that he has seen through many things when he is over 100 years old, so his desert island life must be much more relaxed and comfortable than Robinson.

After determining that there was no need to worry about survival, Yu Tianlai put most of his energy on rebuilding the "Yijin Sutra".

When he was a little apprehensive, according to the "Yijin Sutra" introductory mental method, put on that strange posture and meditated, and tried to re-enter the path of internal cultivation, the first thing was a great surprise.

I don't know if it's because I have crossed that threshold in my previous life, so the "Yijin Sutra" seems to have no entry point for countless practitioners of this practice in ancient and modern times. Although today's Yu Tianlai can't forget the idea of practicing martial arts, he still naturally entered the realm of visualization of the "Yijin Sutra" and successfully condensed a trace of the delicate but pure "Yijin Sutra" true qi in the dantian.

In the eyes of Yu Tianlai, a modern person who has received the influence of "science", the practice of internal strength seems mysterious, but in fact, it is a process of developing one's own potential, just like the various extreme sports he played earlier.

The human body can be said to be the most magical treasure created by heaven and earth. Every human body contains infinite mysteries, and it is like an endless treasure trove of extremely great power.

It's a pity that most ordinary people are ignorant and ignorant, and they can't develop one-ten-thousandth of the mysterious treasure in this treasure house in their lifetime.

Whether it is extreme sports or internal exercises, the ultimate goal is to open the door to this treasure house and take out the treasures for their own use.

Compared with extreme sports, which rely on the great sense of crisis hovering on the edge of life and death to stimulate one's potential, the ancient and mysterious method of internal strength practice is undoubtedly more scientific and efficient.

The first step in cultivating internal strength is to use the techniques of visualization and breathing to stimulate a certain point in one's body and transform the essence contained in it into a trace of original true qi.

Because the Ren vein "Guan Yuan Acupoint", which is called the "Lower Dantian", is the place where the essence is hidden, and the essence is the most abundant and easy to activate, so throughout the ages, nine out of nine in the internal martial arts have taken this acupoint as the starting point of practice.

This entry level is simple, in fact, the most exquisite person's understanding and qualifications, there are countless martial arts practitioners in the world, can pass this level and sprout a sense of anger, and really embark on the road of internal practice, is always only a few of the few. And high-end exercises like "Yijin Jing", which not only involve understanding and qualifications, but also involve the spiritual realm, are even more difficult to get started.

Since Yu Tianlai has once again started cultivating this wisp of Origin True Qi, the next thing is to drive this wisp of True Qi to dredge the eight veins of the Qi Sutra, and at the same time stimulate the essence elements in the acupoints along the way, transforming it into True Qi bit by bit to strengthen himself. After completely penetrating a meridian, the true qi can form a perfect circulation in the meridians, each cycle is called a "small Zhoutian", which can lead to the transformation of the essence of all the knots along the way into true qi, and at this time the internal power is cultivated into a layer.

The pass that penetrates the eight veins of the Qi Sutra and the intersection of Ren and Du is also the ninefold realm of internal cultivation. After the pass between the two veins of Rendu is opened, the eight veins of the Qi Jing can be connected end to end, and the true qi runs in a large circulation between the eight veins, and the efficiency of inducing the essence of the whole body to be transformed into true qi is higher, and each large cycle is called a "Great Zhoutian".

If we talk about the shortness and length of the internal strength of each school, we can see how many meridians can be developed by this exercise. If the ninefold exercises that penetrate the eight veins of the Qi Jing and serve as the superintendent at the intersection pass are complete, this mental method is worthy of the word "peerless".

And on top of this ninefold realm, if you can open up the entrance of heaven and earth again, you can attract the infinite vitality of the vast heaven and earth outside the body for your own use. This realm is the legendary "unity of heaven and man", also known as "innate".

It's just that in modern times, the practice of internal strength has become a legend. In Yu Tianlai's previous life, not only the innate realm also only existed in legends, but even the ninth-level realm of the day after tomorrow also became a masterpiece. is as strong as the Baimei Daoren, who is known as the "first person in the world", but he only managed to penetrate the eight veins of the Qi Jing without making Ren Du intersect, and stopped at the eighth peak.

Yu Tianlai before rebirth also came to this point. Later, the more he gave birth to a strange feeling, it seemed that there was a mysterious force restricting him in the dark, so that no matter how he practiced, his skills were only getting deeper and deeper, and he was never able to get through the last level of the intersection of Ren and Du, and it was the sublimation of the True Qi from the Small Zhou Tian Cycle to the Great Zhou Tian Cycle.

When he guided that trace of Origin True Qi to begin to penetrate the meridians and activate the acupoints, he got a great surprise. It turned out that although the internal force of his previous life had mysteriously disappeared, the eight veins of the Qi Jing that had been opened up were not occluded. On the contrary, after the body has evolved through rebirth, these meridians that have penetrated and expanded in previous lives become wider and stronger.

This means that this reborn Yu Tianlai naturally has the eightfold realm of the day after tomorrow, and all he needs to do is to use that trace of origin true qi to directly carry out the small Zhou Tian cycle, and by activating the acupoints, transforming the essence element, so that the true qi is getting bigger and bigger like a snowball.

Saving the effort of opening up the meridians bit by bit, and because he had already had a practice experience in his previous life, he could avoid some detours and mistakes to the greatest extent, and the speed of his cultivation in this life must be terrifyingly fast. Yu Tianlai roughly estimated that according to the speed of this cultivation, he would only need a few years of work to recover all the strength of the peak period of his previous life.

Yu Tianlai was full of longing in his heart: "Perhaps, in this life, I can get through the intersection of Ren and Du and advance to the realm of the Nine Heavens of the Day After Tomorrow." Or even go one step further and touch the legendary 'innate'. After all, there are exercises of the innate realm in the 'Yijin Sutra' that I practice. Among the allusions that circulated in the martial arts, the masters of the innate realm did exist in the early and middle Ming Dynasty, and they gradually became extinct in the late Ming Dynasty. Even in the early Qing Dynasty, there were also masters of the Ninefold Perfection of the Day After Tomorrow......"
