Although it can be seen that this is a body refining exercise, it is just a few thousand words, but it is a bead of words, obscure, and difficult to understand.

After a long time, Zhang Hai rubbed his eyebrows, finally understood something, closed his eyes, and began to operate according to the method mentioned above in the Heart Sutra, and the slightest aura gathered on the surface of Zhang Hai's body and slowly penetrated into the skin.

Hurt!

It seemed that something was constantly tearing the skin, Zhang Hai's cold sweat flowed out at once, this is the aura that has not passed through the spiritual veins rampage in his skin, if Zhang Hai opens his eyes, he will find that his skin is divided into pieces after pieces like a dry riverbed, and you can even see flesh and blood in the gaps, which is very scary.

Hold back the pain and continue to run the exercises, could there be anything more painful than him opening his pulse? That's all here, what's this!

Finally, when the skin cracked to a certain extent, the vitality precipitated in Zhang Hai's body emerged, and he began to continuously repair the damaged places, and finally the two reached a stable balance.

"I see, this skin refining is constantly tearing the skin and healing, in this process, the aura and vitality are perfectly integrated, penetrating into the skin, making the skin several times tougher."

"It's just that it's too abrasive!" The skin is constantly cracking, repairing, and re-splitting, and the pain is several times greater, and it is constantly getting stronger and stronger.

It's just a matter of Sunday, Zhang Hai immediately put away the exercises, lying on the ground soaking wet, breathing heavily, there was a stench in the air, which was filth seeping out of the skin.

Zhang Hai lay and looked at the top of the thatched house, and the skin on his body was slowly healing.

"It's only been a quarter of an hour, and I can't bear it anymore, how to cultivate, but it's really powerful, just one cultivation can already feel that the skin is much tougher, I'm afraid that even a few more low-level pseudo-spiritual techniques like the Water Archery Technique will be difficult to cause any substantial damage."

"That's natural, if it's so simple, how can it be called the world's first body refining exercise, I think this is the exercise that countless body cultivators are eager to do."

The milky voice appeared in Zhang Hai's mind again.

"Who...... Black light" Zhang Hai was startled at first, thinking that someone was secretly approaching him, but he reacted in an instant, and in Zhang Hai's memory, only the black light would say old-fashioned words in this milky voice.

"What kind of black light, telling me not to guard my lord" The voice sounded again.

Zhang Hai looked around, but he didn't see the black light

"Don't look for it, I'm talking to you with my mind, if you don't keep the Heart Sutra if you don't practice, you will have a special connection with me, I don't have to come out to speak, you must know that every time I come out, I will lose a lot of vitality, you kid is really, holding such a good exercise and only practicing until now, I don't keep the Lord to wait for so long. There was a thick resentment in the voice, but it looked cute with that kind of voice.

"Is it a divine thought?" Zhang Hai asked rhetorically

"It's really shallow, just your little divine thought and divine communication, I really didn't expect your clan to become like this, it's really unpredictable, hey" Hei Guang's tone suddenly felt a little regretful.

"My clan?" Although there were thousands of doubts in his heart, Zhang Hai instantly grasped the key point.

It seems that there are some things that I don't know yet.

"Forget it, let's not talk about it, if you accidentally say it, not only you and me, this area will be finished. The black light seemed to think of something and didn't say more.

"This area is going to be dangerous" Zhang Hai was shocked, he didn't know how big the area in the mouth of this black light was, whether it was this spiritual plant cultivation area or Baicao Mountain, whether it was a case or a country!

"You don't have to think about it, as long as you know that you have something different, anyway, your clan doesn't know how long it has been extinct, this kind of problem is better for you not to understand now, since you have cultivated the Heart Sutra, then I will tell you some things about cultivation" The black light seemed to have some taboos to divert the topic

"Refining the body, refining five outside, refining three inside, and uniting into one. External refining five, skin, flesh and blood marrow, pay attention to the strength of the body, that is, the external recognition of the refining steps, internal refining three, essence and spirit, practice is the soul, only a very small number of exercises will be recorded, and these are all the top exercises between heaven and earth, can reach this point, move mountains and reclaim the sea, shatter the void and pinch it with your hands, as for the final unity, there is only the heart sutra between heaven and earth, as long as you do it, you will transcend life and death, heaven and earth will be destroyed and your body will not die, and everything will be destroyed without the body being damaged"

"Heaven and earth are destroyed but one's body is immortal, and all things are destroyed but the body is not damaged, isn't that the achievement of eternity, will someone achieve it?" Zhang Hai muttered

"Yes, this Sutra of Failure to Keep the Heart is written by him, and I am just a collection of these words. ”

"Who has been able to come to this point?" Zhang Hai was a little curious, compared to such a powerful character, even if time passes, he will definitely leave a lot of legends.

"I don't know, this memory is very confusing, maybe it's too powerful, the memory can't bear it, or maybe that person doesn't want people to know about the seal" The black light is also very confused, once it thinks of the specific identity of that person, the memory will be chaotic and can't see anything.

"But you have to know that you have now cultivated this exercise, but it is equivalent to inheriting that person's inheritance, originally with your qualifications, you are not qualified to practice this level of exercises, but you are the descendant of that clan, although the bloodline is weak, it is extremely pure, although this clan is gone, but the dignity of this bloodline is eternal, but it makes you have this qualification" Hei Guang narrated.

"Now that you have taken over this inheritance, you can't lose its name, from now on, you have to cultivate seriously, I will continue to guide you, looking at your state, it is estimated that it will be difficult to cultivate again today, and you will start systematic cultivation tomorrow, and finally remind you, don't fall too far behind in spiritual cultivation, if you don't keep the Heart Sutra, even if you are powerful before internal refining, there is no increase in lifespan, and you can't cultivate without the support of Shouyuan. ”

Shou Yuan has always been a major drawback of refining the body, even if you don't keep the Heart Sutra, a practice from eternity, you can't avoid it.

"Okay, I'm tired after talking so much today, you kid should hurry up and find some treasures full of life, otherwise I will be so weak if I don't keep the adult. "The black light has no good air, it doesn't know how many years it has been in an ancient tomb because it has lost its vitality, and it only woke up after being dug out by Boss Xue and sucking their vitality, and what is most lacking is the rich vitality.

After finishing speaking, Zhang Hai didn't hear the black light and spoke again.

At this time, Zhang Hai's physical strength also recovered a lot, and he made a bucket of water and carefully cleaned it before he felt comfortable.

Although he has obtained such a powerful inheritance, it is not his own strength after all, and it can only be said that it may be easier to walk on the road of spirituality. As for the clan mentioned by Heiguang, it gave Zhang Hai a strong and unreal feeling, so he suddenly said to a beggar that you were once a prince who destroyed the kingdom, but did you change the status quo of the beggar, no.

Zhang Haike is a very realistic person, even if this clan was once so powerful that it surpassed everything, it was only in the past.

Sitting cross-legged, when he was refining his body just now, he felt that his aura seemed to be able to impact the fourth layer of the open vein, and now that he was in good shape, it was time to break through.

After several months of cultivation, the aura in Zhang Hai's spiritual vein was already a little rich, and under the mobilization of divine thoughts, it slowly flowed in Zhang Hai's meridians, and when he reached the entrance of the fourth spiritual vein, he drilled into it fiercely.

Zhang Hai snorted, but he didn't stop after all, this pain was not very unbearable for him.

The time of a stick of incense slowly passed, and Zhang Hai stood up.

The fourth layer of the open pulse has finally arrived.

Zhang Hai walked into the courtyard, pinched the trick with one hand, and said something in his mouth, and a water arrow slowly emerged, which was the water archery technique.

Zhang Hai got this low-level pseudo-spiritual technique from Li Xingxiu, and he had long been familiar with it, but the total amount of spiritual energy in his body was too small to form, and now Zhang Hai had opened the fourth layer of pulse, and the spiritual energy in his body was finally able to support the consumption of water arrows, which meant that Zhang Hai's spiritual cultivation had finally brought about a substantial increase in strength.
