After observing the spiritual sea, he carefully observed the changes in his physical body again, and sure enough, as the old man in the ice coffin said, his body had been turned into a congenital and leakless body.

The so-called congenital body is a special constitution that is unique to the baby during the period of time from the mother's body to the time before birth.

Human cultivation is a process of absorbing the aura between heaven and earth and incorporating it into itself, but in this process, there are different ways and methods, and there are also different speeds and efficiency.

Among them, the speed and efficiency are determined by these factors.

The first is the environment you are in, the more aura you have in the place, the greater the maximum value you can absorb, which will increase your cultivation speed, and will not slow down your cultivation speed because you can't absorb enough aura, which is also the gathering spirit array, gathering spirit pills and other ways to increase the gathering speed of spiritual energy, and the gathering spirit array that increases the density of spiritual energy in a place is very popular, and even the major families, the Xuanyuan royal family will deploy the gathering spirit array.

The second is one's own absorption speed, which is one of the qualifications required for cultivation, and it is also the most important, everyone's absorption speed is different, and the affinity for aura is also different, so this is also an important reason for the speed and efficiency of cultivation.

And according to the second article, another topic can be deduced, special constitution.

Everyone has a chance to trigger an awakening with a special constitution, but in terms of probability, it is very small, and it can even be said that there is none.

The strength of the father's generation, or the strength of the cultivator in the ancestor, then the chance of his descendants wanting to awaken a special physique will be much greater, which is closely related to the bloodline inheritance, and the family with top cultivators is more prone to have a special physique.

Among them, the innate body without leakage is an extremely special physique.

There are also categories of physique, for example, if Ke Musen transforms into a human, then his physique must be life, or a natural body, born close to various elements in heaven and earth, and born with affinity, the power of life will give him infinite physical strength, rapid recovery of injuries and other special abilities.

In the process of cultivation, everyone must absorb the aura of heaven and earth, enter their own body, follow the direction of the Zhou Tian cycle, turn around in the body, form a complete cycle, and finally incorporate it into the dantian, thoroughly absorb and refine, and adopt it for their own use.

And the whole process of cultivation is not how much is incorporated into the body from between heaven and earth, but in the end, how much is absorbed and refined in the dantian, which in addition to the aura that enters the muscles, bones, blood, and tendons during the Zhou Tian cycle, it will also continue to volatilize to the outside world and return to the heaven and earth.

In addition to the speed of outward volatilization, it also depends on one's own physique, and the function of the congenital body at this time is highlighted.

The congenital body without leakage can block all the pores of a person, and speed up the circulation of the week, speed up the absorption of muscles, muscles and bones, increase the density of the aura incorporated into the body from the outside world, and even after reaching a certain realm, the aura incorporated into the body can be transformed into liquid and solid, thereby slowing down the volatilization rate of the aura.

This is the primary function of the innate infallible body, and after the cultivator with the innate infallible body reaches a certain realm, the innate indelible body is conceived from the mother's womb as a human being, and the constitution conceived at that most mysterious moment will reveal its ultimate function.

These are not mentioned for the time being, after all, Xue Xintang's congenital inleakable body is just artificially created by the old man of the ice coffin, after all, the great monk who has reached his realm can close the pores of an ordinary person's body and not block the normal operation of his body circulation, it is still very simple.

It's just that there is a time limit, after all, the old man of the ice coffin will not be by Xue Xintang's side to adjust it for him anytime and anywhere, if an ordinary person, even if it is a monk, a low-level monk will block all the pores around his body for a long time, it will be extremely harmful to the body, which is also the power of the congenital impermeable body, after all, the top monk like the old man of the ice coffin will not be able to block the pores of an ordinary person or a low-level monk for a long time, and the congenital inleakable body can easily do it, without any side effects, and it will also increase the cultivation speed, this innate innate indelible body can be different from artificial, and its cultivation speed can exceed the artificial tens, hundreds of times.

However, it is said that this is also normal, after all, if a special physique can be created by any top monk, then there are no rules between heaven and earth, and there are no rules.

But it was this time limit that also made Xue Xintang extremely happy, and he practiced the cultivation method given to him by the old man of the ice coffin for the first time.

I saw that in the quiet room where Xue Xintang was located, a huge invisible vortex was condensed around Xue Xintang, and the stars around were floating towards Xue Xintang, and the whirlpool was turning faster and faster, from the very beginning of the point of light floating by itself, to the vortex forcibly swept all the surrounding points of light.

Countless points of light condensed, and entered Xue Xintang's body along the whirlpool, with the continuous influx of light points, the whirlpool continued to expand, Xue Xintang's original gray hair also became black, the wrinkles on his face seemed to be ironed with an iron, and the whole person became younger, in addition to these obvious changes in appearance, there were also internal changes, shriveled muscles, fragile bones, aging organs, one by one, as if they had been injected with vitality, restoring their youthful state, even better than that.

As time passed, Xue Xintang slowly opened his eyes and ended his cultivation.

The spiritual power swept by, observing that he had changed greatly, Xue Xintang had some tears in his eyes, clenched his fists hard, felt this power, put his hand on his chest, and felt the beating heart with his hand, Xue Xintang felt the power of life at this moment, and felt the feeling of youth.

After feeling the changes in himself for a while in the quiet room, Xue Xintang felt extremely satisfied, and at the same time, he was even more grateful to the old man in the ice coffin.

The next day, Zhan Debang, Yang Yunchao and the accompanying guards met Guo Jingxiang at the gate of Danzhou City after replenishing the supplies needed along the way.

Xue Xintang, as the master's family, naturally had to go to the city gate in person to see off their group.

And when Xue Xintang arrived at the gate of the city, Guo Jingxiang, Yang Yunchao, and Zhan Debang couldn't help but be surprised when they saw Xue Xintang, who had changed a lot overnight.

"Elder Xue, you ...... What are you?"

Guo Jingxiang was the first to ask questions, and listening to his slightly trembling words, you could know how surprised he was at this time.

It is also true, after all, when they were separated just yesterday, Xue Xintang still looked like he was in prostration, even if he regained some strength later, he was still pale and bloodless.

And when I saw Xue Xintang again today, he looked like this, his hair was black, his face was full of red light, and he looked extremely healthy, which was very different from the dying appearance yesterday, when he first saw Xue Xintang, Guo Jingxiang almost couldn't recognize it.

This is an old man in his eighties, this is clearly a middle-aged man in his forties, in the prime of life!

Xue Xintang also knew that his appearance had changed greatly now because of the ancestor's washing of muscles and marrow, purification of the soul, and the cultivation of the exercises given by the ancestor, but these things were not easy to explain, this was the secret of his Xue family, even if he chose the marshal behind Guo Jingxiang in this catastrophe, he could not easily reveal these secrets.
