After the battle, An Xiaoyu felt that the use and circulation of the vitality in his body were smoother, and there was a desire to impact the promotion in his blood.

The dantian vitality condensed into a line and rushed towards the Purple Palace Acupoint, after thousands of impacts, coupled with taking divine blood and pills, the tenacious barrier was finally broken through an hour later, and An Xiaoyu was promoted as he wished, reaching the realm of a second-order demon master.

"The promotion has been too fast in the past two days, and now that it's getting late, the underground is quite safe, so I have to stabilize and stabilize my cultivation. ”

An Xiaoyu held back the joy in his heart, and continued to cultivate cross-legged, his vitality running over and over again in the meridians, thinking back to the battle with the Peach Tree Fairy brothers and sisters, the battle with hundreds of earth dragon beasts, and finally the gains and losses of the battle with the earth dragon beast king, and the experience of using martial arts.

The morning sun rose, and a few rays of warm sunlight shot in through cracks in the ground overhead, and An Xiaoyu was still cultivating.

After stabilizing his cultivation, four new skills came to An Xiaoyu's mind: "Copper Wall and Iron Wall", "Earthquake and Vertigo", "Iron Hoof Trampling" and "Water Comes to Earth Weir".

It turned out to be an earth-attribute skill contained in the source of loess of the Earth Dragon Beast King. These skill cultivation methods were absorbed by An Xiaoyu with the source of loess, and they also entered An Xiaoyu's sea of knowledge. Now that the cultivation is stable, it is the time to cultivate them.

An Xiaoyu's "Ape Demon Transformation", "Spirit Ape Xuanzhi", "Death Entanglement", and "Death Piercing" are all kung fu in hand.

"Copper wall and iron wall" is external power, divided into three levels.

After the cultivation of the "first-level copper wall and iron wall", it can make the body as thick as loess, natural sandbag, just like the physical strength of the general earth dragon beast, and form an earthen wall four zhang wide and two zhang high and two meters thick in front of the enemy when facing the enemy.

After the cultivation of the "second-level copper wall and iron wall", it can make the body as solid as a rock, withstand thousands of hammers and chisels, and form a rock wall five zhang wide and three zhang high and two meters thick in front of the enemy when facing the enemy.

After the cultivation of the "three-level copper wall and iron wall" can make the body as hard as copper and iron, heavy as a rock, the wind cannot blow, the water cannot fall, and when facing the enemy, a copper wall with a width of six zhang and a height of two meters can be formed in front of the enemy.

"Ground Stunking" and "Iron Hoof Trample" are both foot skills.

"Shaking the ground and stunning" with both feet on the ground, the ground crack is dizzy, and it is also divided into three levels.

"Level 1 Earth Stun" has a radius of 10 zhang, stunning enemies for 3 seconds.

"Level 2 Earth Stun" can affect a radius of 15 feet, stuning enemies for 5 seconds.

"Level 3 Earth Stun" has a radius of 20 feet, stunning enemies for 7 seconds.

"Iron Hoof Trampling" is to trample on the enemy, which is also divided into three levels, "Iron Hoof Trampling" makes the enemy lose his body, "Iron Hoof Trampling" makes the enemy break bones, and "Iron Hoof Trampling" makes the enemy turn into blood and mud.

Both of these skills need to be cultivated into "Loess Armor" to strengthen the body, and then cultivate the legs and feet, so that the feet are like two heavy hammers to attack, which is actually the same kind of skill.

"Water to Earth Weir" is similar to "Copper Wall and Iron Wall", both are defensive skills, the difference is: "Copper Wall and Iron Wall" is an external skill, and the single defense is strong, but "Water to Earth Weir" is an incarnate causeway, and the group defense of the water system is attacked, and the Earth Dragon Beast King will not be now.

The Earth Dragon Beast King should have only cultivated "Earth Shaking Vertigo" and "Iron Hoof Trampling", "Copper Wall and Iron Wall" and "Water Comes to Earth Weir" It has not yet learned, otherwise if it is displayed just now, An Xiaoyu may not be able to win easily.

"It seems that the 'water comes to the earth weir' can't be practiced now, the 'iron hoof trampling' is stepped on the body, both feet are bloody, too buried, Mi'er must not like me to make my feet full of blood, this doesn't need to be learned, you can give it to those who are not afraid of dirty in the future, learn the other two first, and learn to deal with bloodthirsty flies in the future." An Xiaoyu thought secretly.

This is the cave of the Earth Dragon Beast King, and ordinary Earth Dragon Beasts and cultivators don't dare to come in to find death, An Xiaoyu is relieved about safety, and said hello to the three of Mi'er, and began to cultivate the "Loess Armor" first.

An Xiaoyu took out the Earth Dragon Ball of the Earth Dragon Beast King and began to absorb the energy in it.

An Xiaoyu had already absorbed the source of loess, and there was a carrier of earth attributes in his body, and the light yellow spots of his spleen reacted, and these earth attribute energies entered An Xiaoyu's body without resistance.

However, it did not enter the dantian, but attached to the skin, making the skin feel itchy and unbearable, which may be due to the difference in the earth-based body structure of the ape's body and the earth-dragon beast, resulting in an adverse reaction.

Fortunately, An Xiaoyu was already mentally prepared, and when he ran the dantian Yuanzhu, his heart couldn't be turbulent, but he was able to hold on.

Gradually, An Xiaoyu's skin all over his body developed countless yellow spots, and the cell structure of the skin was being changed by the earth attribute energy.

As he continued to absorb the energy of the Earth Dragon Ball, the yellow spots turned into yellow spots, and then into loess-like lumps, and finally the lumps were connected together, covering An Xiaoyu's whole body like a layer of loess armor.

Three days later, An Xiaoyu was already able to summon the loess armor at will.

The loess armor is as thick as five inches, just like An Xiaoyu wore a thick sandbag, but there is a palm-sized piece of armor at the mouth of the heart that is rock-shaped, which is estimated to be made of the Earth Dragon Ball of the Earth Dragon Beast King.

"I'll try my defenses again. ”

An Xiaoyu's heart moved, his vitality gushed out, flying sand and stones, and the earth and stone more than ten meters in front of him seemed to be manipulated by an invisible big hand, turning into an earth dragon around An Xiaoyu, forming a thick cylindrical earth wall, which strictly protected An Xiaoyu.

"It's a pity that it's just an Earth Dragon King Ball, it seems that we will have to find more earth-based energy to strengthen the evolution armor in the future. An Xiaoyu said regretfully.

"Little Stone, be content, you have refined all the Earth Dragon Balls, and now the loess armor can resist ordinary water-based monsters. Mi'er saw that An Xiaoyu was still not satisfied, and struck.

"Hehe, I know, it's just talking. I'll try to cultivate 'Shaking the Earth and Stomping' again, and I won't learn 'Iron Hoof Trampling', our family loves cleanliness, and you can't like me with blood and brains on my feet, right?" An Xiaoyu said with a smile.

"It's good to know, who is your Mi'er?! Take advantage of me, see if I don't twist your ears. Mi'er Qiao blushed and reached out to twist An Xiaoyu's ears.

The key to "earth-shaking vertigo" is to concentrate the whole body energy formed by the "loess armor" into the legs, so that the strength requirements for the legs are greatly enhanced.

Although An Xiaoyu's flesh is strong, the strength of the bones in his legs is not enough to withstand such a powerful energy.

After a few attempts, the energy that my legs could bear was less than one-tenth of the total energy, and I stepped on the ground a few times, except for leaving two and a half-foot-deep footprints and shaking up a little dust, there was no fluctuation at all.

"How to improve the strength of your legs?" An Xiaoyu was worried.

Seeing that An Xiaoyu was a little depressed, Mi'er smiled and reminded: "Although you have reached the second-order demon master now, the strength of the bones in your legs is still very weak, you just try to cultivate the second trick of refining tendons and washing the marrow and refining the body, 'Bone Refining Technique', when the leg bones are strong, you can burst out with powerful energy." ”

"yes, I forgot about it. An Xiaoyu patted his head, and when he cultivated to the realm of a demon master, he could cultivate the bone refining technique.

"You practice the 'Bone Refining Technique' by yourself, and I want to go to the Formation Pavilion to have a look. Mi'er said.

"What are you going to do there?" An Xiaoyu asked.

"I want to study the defensive formation, see what items need to be collected, and set up a defensive array on the periphery of Huaguo Mountain in the future to see who dares to bully you. Mi'er said.

"Good Mi'er, kiss one. An Xiaoyu Wang laughed happily.

", don't you mess around anymore, I won't arrange it for you. Mi'er said angrily.

"Okay, I'll take it, don't make trouble. An Xiaoyu begged for mercy.

Coming to the Formation Pavilion, Mi'er took the defensive formation, and An Xiaoyu left the Jade Jian Space and went to the Ear Space to study by himself.

An Xiaoyu recalled the information of the body refining decision, and it was clear in less than half an hour.

The second trick of refining tendons and washing the marrow and refining the body ----refining the bones" is different from the general external skills, requiring the inside and then the outside, first opening up the big and small Zhoutian, and the external strength is born from the inside, which is similar to the cultivation principle of "Divine Ape Transformation", and it is estimated that it is the same powerful stunt.

Step 1: Stretch the spine, first refine the spine. The force is born from the waist, no matter what martial arts action, it is based on the waist as the axis, and the internal strength is issued from the waist.

Step 2: Loosen the hip and open the sacrum, and refine the hip sacrum. The flexibility and strength of the legs depend on the roundness of the hips and sacrum, and the internal strength of the hipsacral roundness can be sent to the legs.

Step 3: Loosen the knees and touch the feet, and refine the knee bones. If the knee is not loose, the force will not reach the sole of the foot, and if the force is difficult to reach the sole of the foot, it will hit the human body without much penetration.

Step 4: Roll your legs and kick the pier, and raise your tibia. Exercise the firmness of the legs, train the strength and explosiveness of the legs.

An Xiaoyu is familiar with the bone refining technique, and first practice the first step to stretch the spine. If it is completed, the spine can be lengthened by one foot, the buttocks can touch the ground when squatting, and the vertebrae can overlap together and coil into nine curves, which is called "shaped like a nine-curved ball".

An Xiaoyu walked to a soil wall, cut the soil wall straight and flat with his palm, and then put his feet together, stood facing the wall, inhaled and squatted gently, his toes, knees, and nose tips were close to the wall, and he exhaled and stood up gently, and his toes, knees, and nose tips still couldn't leave the wall during the process of standing. When you stand up and exhale, your mind consciously thinks of straightening your spine.

Two days.

An Xiaoyu's knees and the tip of his nose drew deep marks on the wall, and his whole body moved up and down as if embedded in the wall. When he achieved 8,100 squats, the Monkey King felt that the spine was wrapped in the heat flow of vitality, and the ligaments between the spine were stretched little by little, and finally reached the small completion of stretching the spine. His legs went limp, and he collapsed to the ground.

In the past two days, Mi'er and Peachtree Fairy brothers and sisters have persuaded An Xiaoyu to rest many times, but it has been ineffective.

Now seeing that An Xiaoyu is tired, they have appeared one after another and come to condole.

"Why are you trying so hard, take it step by step, or you'll hurt your body. Mi'er said distressedly.

"I wanted to push the limits and see the strength of my muscles, and for the first time I felt both legs sore and swollen, unconscious, as if they weren't my own. But luckily, I feel like my spine can be lengthened by an inch. An Xiaoyu lay on the ground in a big word, panting.
