A three-meter-high pile of sand, a large water tank full of medicinal smell, the black potion in the medicine tank is boiling and boiling, and there is a pile of fine iron powder next to the large water tank. It was the cultivation material prepared by Qin Yi.

"Ha, ha, ha!" Qin Yi stepped on his legs, shouting loudly in his mouth, quite like a martial artist in the rivers and lakes, he grabbed two large handfuls of wet sand in his hands, and with his hands with full strength, he slapped heavily on the body of the ****, and then rubbed on the skin with full strength.

The sand is not fine sand, but large grains of sand with sharp edges and corners, which are similar to small pebbles. However, now Qin Yi's body is extremely strong, and under the hard rubbing, all the big sand grains have been crushed, as fine as powder, but not even half of the traces have been left on the skin.

Qin Yi didn't stop, once the sand grains were crushed, Qin Yi grabbed two large handfuls of sand again, pressed them on his body again, and rubbed them hard, so again and again, a cup of tea, a small pile of sand was piled up under Qin Yi's feet, and the skin was red again, like blood floating to the surface.

Qin Yi rubbed his whole body with sand, not even letting go of the vital points, rubbing hard, frowning in pain and not stopping, four hours later, Qin Yi's body was already red, sticky with powder-like fine sand, and the fine sand powder used was piled up on Qin Yi's thighs.

When it was time to soak the potion, Qin Yi didn't stop for a moment, jumped up suddenly, fell into the big water tank, the hot potion didn't pass the body, and the hot hair of Qin Yi rolled upside down, and he gasped, but soon, Qin Yi took a breath, and even his head sank into the potion, so that the effect of the potion reached the whole body, and it took a long time before he surfaced for ventilation, took another breath, and sank into the potion again.

This potion was soaked by Qin Yi for three hours, and although the water in the big tank was still boiling, it was already clear and no longer black, this was because the medicinal effect in the potion had been absorbed by Qin Yi.

Qin Yi's entire body had become red, just like a red-hot prawn ball, but at this time, the effect of his medicine was spreading, and the veins were unblocked, which was the best time to cultivate the iron cloth shirt.

Qin Yi changed a jar of water, and then put in the medicinal herbs to continue to burn, because after rubbing the iron powder, it must continue to be soaked.

The third step is to rub the iron powder, Qin Yi evenly and carefully applied the pile of fine iron powder to the body, painted all the places on the body except for the eyes, and even filled the pores, and applied a thick layer, the whole body was pitch black, like a sculpture made of iron clay. After the iron powder was applied, Qin Yi sat on the ground and carried the cultivation method of the iron cloth shirt.

The skin soaked in the potion is moist, the pores are dilated, and the heat is overflowing, which is very easy to stick to the iron powder, and Qin Yi can feel the cool taste of the iron powder. As the mind flowed, a burst of coolness slowly penetrated into the skin along the pores, and then gradually disintegrated and was absorbed by Qin Yi's skin.

This made Qin Yi very surprised, could it be that these iron powders were actually absorbed by the skin?

Transporting the inner view of the divine sense, the running route and state of the iron powder were displayed in front of Qin Yi. Qin Yi found that after the iron powder was absorbed into the subcutaneous area, it encountered the true qi of Qin Yi's operation, and it underwent drastic changes, which was broken down into infinitesimal sizes, and then absorbed by the cells of the skin.

These energies, which gave Qin Yi the feeling of being metallic, were metallic energies, but its color was not the gold that Qin Yi had known before, but silver.

A new question arose, according to Qin Yi's existing understanding, metallic energy was golden, but why did it take on different colors.

Could it be that it has a more subtle structure that Qin Yi doesn't know?

At this moment, Qin Yi felt that he knew too little about energy, and there was such a complicated problem just by knowing one kind of energy.

It's a pity that Qin Yi's divine sense is not strong enough, and he can only feel the energy of a certain attribute, and if he wants to study its structure in depth, it is already beyond his strength, so he has to give up.

The most basic and essence part of iron powder, the metallic energy is easily absorbed by Qin, and most of the residue is left on the surface of the skin or discharged by the pores, and even brings out some harmful substances in the body, leaving some odor on the surface of the body.

Therefore, Qin Yi washed off the iron powder and the harmful substances discharged, and replaced it with a new layer of iron powder to reabsorb it.

Unlike the Golden Bell Jar, which absorbs metallic energy and adds some wood-attribute energy assistance, Qin Yi feels that in addition to absorbing metallic energy, the iron cloth shirt also has some water-attribute energy, and the two energies work together to form the transformation effect of this exercise on cells.

After changing the iron powder eight times, the skin felt full and sluggish. Qin Yi stopped the application and entered the medicine tank to soak and wash his body.

After the flushing is completed, a prompt comes from the system: "Your attributes have been improved in your cultivation, the proficiency of the Iron Cloth Shirt in the exercises has increased, your physical strength has increased by 2, and your immortal power has increased by 1%. Your current stats are 258 Strength, 305 Stamina, 165 Spirit, 280 Dexterity, and 262.51% of Immortal Power. ”

Qin Yi was very dissatisfied with this kind of result, in fact, he didn't know that it was already very amazing to have achieved this kind of result at the beginning of cultivation. Because his body endurance is relatively strong, he changed to an ordinary cultivator, the first time he cultivated the iron cloth shirt, let alone changed the iron powder eight times in a row, and even jumped into the hot medicine tank, it took two or three months to adapt to the temperature of the potion, and then he could only absorb the iron powder once, and with the growth of the cultivation time, the deepening of the attainment of the iron cloth shirt, he slowly increased the number of times he changed the medicine powder.

Practicing iron cloth shirts is not achieved overnight, because the body's absorption limit of iron powder even has a limit on the cultivation time and number of cultivations. Therefore, after Qin Yi finished cultivating the iron cloth shirt, he turned to cultivating the Thirteen Henglian Taibao.

These thirteen horizontal exercises of Taibao are not simply external horizontal exercises of qigong, but are the same as Mangniu Jin, internal cultivation and cultivation, not only to cultivate the hardness of the body, but also to quench the internal organs and forge true qi.

The thirteen horizontal exercises are divided into thirteen sections, the highest section is the Vajra Tai Protection Method, which means to take the body of Vajra, with the power of Vajra, the hundred demons do not invade, and the Vajra is not bad.

This kung fu must be practiced in the sun. Fortunately, simulating sunlight does not necessarily have to be a star, Qin Yi exchanged the simulated sunlight effect to the system, the price is expensive, ten cubic meters, just to cover his body, and the three-day simulated sunlight effect cost Qin Yi 100,000 points.

Standing in the sunlight, Qin Yi stood without hesitation, his hands were flat on his chest, and his mind visualized a huge round star suspended above his head, in a red state, emitting boundless light and heat, light and heat entered Qin Yi's head through Baihui, cleansing his whole body with the turbulence of qi and blood, and filling every part of his body with the energy of the stars.

This visualization is to turn the virtual into the real until the real effect of absorbing energy is achieved in the visualization, and then it is initiated.

It took Qin Yi twenty-four hours to visualize the shape of the stars, and it took twenty-four hours for the energy to enter the body, and on the third day, Qin Yi finally entered the state, and the amazing energy of heaven and earth was sucked in, and it continued to enter the Baihui acupoint above Qin Yi's head. You can see the white vapor steaming above Qin Yi's head, like water vapor evaporating in the sun.

Qin Yi raised his eyebrows, and immediately understood that what the Thirteen Henglian Taibao absorbed was the same aura of heaven and earth, not pure sunlight, and visualizing the stars was just to achieve this purpose.

However, these thirteen horizontal exercises made Qin Yi observe a new kind of attribute energy: light attribute energy.
