After exchanging time, a white light appeared above Qin Yi's head out of nowhere, covering Qin Yi's body, and swishing Qin Yi into the white light.

In an instant, Qin Yi had already appeared in an empty space, this space looked like there was nothing at a glance, the width and height were about a thousand meters, and it was isolated from the outside world by a semicircular milky mountain-colored shield. As soon as Qin Yi appeared here, he felt the surging aura of heaven and earth, the concentration of aura in the flood was amazing, and the aura of heaven and earth here was ten times higher than that of Lei Mountain's residence.

"It seems that this is the place of cultivation that has been exchanged, and in three months, ten times the aura of heaven and earth...... Go for it!"

Tongtian Tu Qin Yi has already cultivated one hundred and eight postures, and next, it is time for Qin Yi to cultivate the golden bell jar. However, Qin Yi did not only cultivate the Golden Bell Jar, after all, it was too monotonous to only practice one outer martial arts, so Qin Yi put the Golden Bell Jar, the Iron Cloth Shirt, and the Thirteen Horizontal Exercises Taibao together to cultivate.

Qin Yi sat cross-legged on the ground, put his palms together and raised them above his head, and carried the heart of the golden bell jar.

After a moment's effort, a faint golden light floated on Qin Yi's face, like a thin layer of gold sand covering his face.

This layer of golden light was extremely thin at first, but as Qin Yi's true qi flowed, it began to slowly thicken, and spread to the chin and neck, and then descended to the chest, abdomen, dantian, perineum, thighs, knees...... Qin Yi's whole person looked like a golden man coated with a thick layer of gold paint, and the golden light blurred the air and pierced the eye mask.

Qin Yi's eyebrows were slightly browsy, as if he was asleep, as if he was awake but not awake, and his expression was solemn, like a majestic golden bell with a majestic and immovable treasure.

When the faint golden light came to the knees and covered the knees, it seemed to have reached the limit, and it did not spread downward.

After ten hours of continuous luck, Qin Yi's luck has reached the limit, so he jumped up, his two hands with bright golden light, changed his hand again and again, or fingers or palms or fists, on the shoulders, back, legs, belly, waist, and even the key points of the head on the body kept patting, "pop bang bang", the quiet space sounded the heavy sound of hard objects impacting, but this sound did not seem to sound on the flesh, but like a crisp sound on the metal.

It can be seen that every acupuncture point on Qin Yi's body that has been slapped will temporarily appear a deep indentation, and the true qi on his fingers will drill into the acupoint in a spiral shape, driving the surrounding muscles to roll like waves.

The acupuncture points that were slapped were stimulated, and they opened to the limit unusually, greedily absorbing the thick aura of heaven and earth in the air, quenching the muscles, bones, skin and flesh, and it took a long time to calm down, and after the beating, a hard metallic luster appeared on the surface of the skin, which appeared stronger and stronger.

With the improvement of Qin Yi's strength, this golden bell jar technique has gradually deepened, and now the golden light on the surface of his body has come to his knees, and Qin Yi believes that with a little more strength, he will soon be able to reach the highest level.

Since cultivating the aura of heaven and earth and the energy structure of the three diagrams of heaven and earth, Qin Yi has gained a new insight into both his own internal structure and the aura of heaven and earth in the outside world. Now when cultivating the Golden Bell Jar, Qin Yi took the initiative to analyze the cultivation method of the Golden Bell Jar and the Heaven and Earth Aura it absorbed.

Qin Yi found that when cultivating the golden bell jar, the acupuncture points on the surface of the body were opened to the limit, absorbing the aura of heaven and earth like swallowing dates, no matter what kind of aura of heaven and earth was absorbed, so that the aura of heaven and earth absorbed was extremely large. Qin Yi tracks the flow of these heaven and earth aura in the body, and when looking inside, most of these heaven and earth aura enters the cells of the skin on the surface of the body, causing the cells to change, or evolve.

However, Qin Yi found that only a small part of these heaven and earth aura devoured into the body really entered the cells, which played a role in promoting the transformation of the body, and most of the rest dissipated or fused by other physical tissues, which was either wasted or extremely inefficient in transforming the body.

This small part of the heaven and earth aura that really raises the realm of the Golden Bell Jar is pure metallic energy. It turns out that the golden bell jar transforms cells by absorbing metallic energy, so it's no wonder that cultivation or exercise will emit golden light all over the body.

Since only metallic energy can promote the improvement of the golden bell jar, can we discard other energies and only absorb metallic energy when cultivating? Wouldn't that be more efficient?

As soon as this thought appeared, it made Qin Yi excited, you know, Qin Yi has faintly realized that to increase physical strength and promote body defense, this metallic energy is only afraid of the most critical part, if you can separate metallic energy and absorb it alone, the effect is very different from swallowing dates and blindly absorbing.

Moreover, this method of separating energy can not only be used to improve physical strength, it is applicable to all kinds of exercises, it can be said that you understand the attributes of energy, understand the relationship between body evolution and energy, and then distinguish and absorb them one by one, just like having exercises that are absolutely ahead of other cultivators, just like the stars change, and the speed of upgrading is self-evident.

But when Qin Yi tried to absorb metallic energy, Qin Yi was frustrated to find that understanding is one thing, and doing is another. The heaven and earth aura distributed in the atmosphere did not obey his command at all, let alone absorb metallic energy alone, and could not even separate metallic energy from heaven and earth aura.

Qin Yi realized that, firstly, his divine sense was not strong enough to command the aura of heaven and earth, and secondly, how to absorb the aura of heaven and earth, which kind of aura of heaven and earth to absorb, and the proportion of absorption was not just a powerful divine sense, it must be matched with the corresponding cultivation methods, such as the golden bell jar, the three diagrams of Tongtian, and the strength of the reckless bull. If you want to absorb any kind of heaven and earth aura, you must cooperate with which cultivation method.

In other words, if Qin Yi wants to absorb metallic energy alone, he must create a corresponding cultivation method, and according to the proportion of absorbing metallic energy to the spiritual energy of heaven and earth, which part of his body, muscles, cells, muscles and bones...... Their cultivation methods are also different. It's complicated.

With Qin Yi's in-depth observation of the flow of the Golden Bell Jar's true qi, he found that the original Golden Bell Jar absorbed not only metallic energy, but also a trace of wood attribute energy, but the proportion was very small.

Although this discovery did not thwart Qin Yi's research on the relationship between heaven and earth, aura and physical body, it also temporarily dispelled Qin Yi's wishful desire to absorb metal properties alone, at least before he created his own exercise, such a good thing Qin Yi could not do.

..................

"Your attributes are improved in cultivation, your strength is increased by 1, your physical strength is increased by 5, and your immortal power is increased by 3%. Your current stats are 258 Strength, 303 Stamina, 165 Spirit, 280 Agility, and 261.51% of Immortal Power. ”

The prompt sound of the system came, and he realized that the cultivation of the Golden Bell Jar had entered, so Qin Yi temporarily put it down and turned to cultivate the iron cloth shirt.

The iron cloth shirt, as the name suggests, is the same as the golden bell jar, and it is also an outer door hard family qigong. However, his cultivation method is very different from that of the golden bell jar, and the requirements for external objects are relatively high.

In the early stage, the cultivator of the iron cloth shirt must constantly rub his body with river sand, and also quench it with high-temperature potion, and in the later stage, he must apply iron powder all over his body every day to perform the exercises, and in the end, not only will his body be as hard as iron, but he will also be able to force a layer of hard invisible qi on the surface of his body, so that he can achieve great success.

Fortunately, whether it was river sand, potions, medicine tanks, or iron powder, they could all be purchased from the system, and the price was not expensive, so Qin Yi was able to cultivate smoothly.
