Zuo Le couldn't help but glance at Qin Ziling in surprise when he heard this.

Originally, he saw that Qin Ziling had only broken through in the past three years, and he thought that in addition to his roots, his family was poor, he had no meat and medicinal materials, and his talent and understanding were also very average, but he had perseverance and perseverance in practicing martial arts, and then coupled with luck, he was lucky to break through.

As a result, I didn't expect that Qin Ziling had just broken through the skin membrane realm and would be able to deduce such a conclusion from his own words, but this understanding was already very high.

At least Zuo Le didn't think of this when he first broke through, it was only after the master broke through it, and then he went through actual feelings before he really understood this truth.

"You have a good understanding, that's the truth. Therefore, the purpose of training muscles and bones is to increase strength, to train the power of qi and blood, and to train the skin membrane is to change the nature of blood and qi, to seal the blood and qi in the palms, and constantly temper the qi and blood in the palms, so that it can undergo qualitative changes and produce strength. Zuo Le nodded and said.

"According to this theory, the skin membrane of other parts of our human body has not been cultivated, which is equivalent to leaking air everywhere, which will inevitably affect the tempering effect. Qin Ziling said thoughtfully.

"Theoretically, this is the case, but as I said before, except for the hands and feet, the strength, qi and blood of other body parts are very difficult for us to control, and it is extremely difficult to cultivate other body parts to the skin membrane realm. You can use your strength and palms to slap the iron sand bag, so as to temper and polish the skin film, your belly, your back, although you can also carry the force, but it is impossible to control the power as accurately as the hands and feet, and it is impossible to clearly feel the power to drive the surging of qi and blood inside. Besides, the other parts of the body are far less dexterous than the hands and feet, how do you temper them? It can only be hammered by the hands of outsiders! ”

"But those body parts are not only more difficult to exercise than the hands and feet, but also much more fragile, pretending to be the hands of others, the strength is not under their control, the lack of strength does not have much effect, the force is too great, a bad control will hurt the body, and even disability and death is not uncommon."

"And it's very difficult to practice the skin membrane, just like you, you have practiced for nearly three years with both hands alone, you want to practice other parts of the body, not to mention that there is a lot of danger, you don't know how many years it will take to succeed in practice, at that time you have already decayed your qi and blood, how can you have the opportunity to peek into the realm of strength again? Of course, the financial resources required for this kind of practice are also a bottomless pit. ”

"So your idea is good, but it's not realistic. Only the big sect and the big family, they have a deep background, they will pick out the talents from the door or family, spend a lot of financial resources and manpower, and use secret methods to exercise the body except for the hands and feet. Like Pang Qiwei, the county guard of our Fangqi City, from our Wangpang family in Xiyunzhou Prefecture, he has been extremely talented since he was a child, and he was cultivated by the family and awarded the Tongbei Iron Arm Fist. Not only did he have a secret and precious potion to soak his arms, but he also had two powerful martial artists who were good at controlling his strength taking turns to help hammer his arms. ”

"So as soon as his skin is formed, it covers both arms, not just the palms or feet like the rest of the family does with us. For a person like him, once he steps into the realm of strength, his strength will be more refined and condensed, and his ability will surpass that of a martial artist of the same realm. ”

Speaking of this, Zuo Le seemed to think of something, with a hint of self-deprecation on his face, and changed his words: "I talked too much about your question." Listen to it, don't think about it, it's useless to think about it! ”

"Yes, Zuo Shi." Qin Ziling replied respectfully, but there was a hint of thought in the depths of his eyes.

The strength martial artist helped to hammer it, and he naturally didn't dare to think about it as a martial artist who had just broken through to the skin membrane level, but he had a bronze corpse, and the bronze corpse was connected to his mind, and it could be completely controlled accurately in terms of strength, which was much stronger than any strength martial artist.

No matter how powerful the martial artist is, no matter how good he is at controlling the force, it is impossible for him to communicate with the person who hammers him, and there will definitely be mistakes and deviations in the strength of the hammering, which cannot be just right. I guess this is one of the reasons why even with the talent of the county guard and the secret precious potion can only reach the arms.

Not only that, Qin Ziling was also a god refiner in the realm of exorcism, and in terms of the control and feeling of the blood and qi power of each body part, he was far superior to the martial disciples of the same realm, and was not even inferior to their control and feeling of the qi and blood power of the hands and feet.

Therefore, for Zuo Le, his words were simply redundant, but for Qin Ziling, it was tantamount to Zuo Le pointing out to him another path of cultivation that belonged to him.

Zuo Le naturally didn't know this, glanced at Qin Ziling, and continued: "You just mentioned that the skin membrane in other parts cannot be cultivated, it is like air leakage, this is indeed a problem. Therefore, the predecessors have studied various methods of luck and strength, as well as supporting secret medicines, in order to achieve the purpose of transforming qi and blood into strength. ”

"In terms of luck and luck, compared with other exercises, my cold iron palm does not have too many mysterious and unique features, mainly holding a breath, using the qi and blood power around the body with all his might, and rushing towards the palms in one go, in order to achieve the purpose of squeezing and tempering the qi and blood of the palm and making it qualitatively change. And some sect families, they have some subtleties in the operation of qi and blood power, such as the Xu family of Xujiabao outside the city, and their cultivation strength is stacked wave energy. ”

"It is said that when they are lucky, the power and blood rushing to their palms will rush over wave after wave like ocean waves, which is very mysterious."

"The mystery and uniqueness of my cold iron palm is mainly related to the secret medicine. I have a kind of exotic bird, called the Xuanhan Iron Chicken, which is as hard as iron and extremely fierce. This chicken was hunted by me and some colleagues in the early years from the depths of the Wuyang Mountains and then domesticated. The eggs of the Xuanhan Iron Chicken, combined with some cold precious medicinal materials, can be refined into a secret medicine. When cultivating, taking this secret medicine can change some attributes of qi and blood, making it have a hint of cold and metallic properties, so that when using qi and blood power to press and temper, it can achieve twice the result with half the effort. Speaking of this, Zuo Le's face showed a hint of pride.

Hearing this, Qin Ziling nodded slightly, with a look of understanding on his face.

"Could it be that you can figure it out?" Seeing this, Zuo Le couldn't help but ask curiously.

"Ordinary objects have the property of expanding when heated and shrinking when cold, but the properties of metals are much harder and denser than those of other substances. Zuo Shi used the secret medicine to bring cold and metallic properties to the qi and blood, in fact, it has already had a trace of condensation effect, and the condensed qi and blood will naturally have a greater power and a better effect. Qin Ziling replied.

For another civilized world with highly developed science and technology, Qin Ziling can easily explain these problems with the most basic scientific theories.
