Yi Yun practiced bone refining all night, but he couldn't absorb the energy in the barren bones indefinitely.

Yi Yun found that when he absorbed energy to a certain extent, he felt overly full, as if he had eaten enough and could no longer eat.

If he continued to absorb energy at this time, he would feel some chaotic energy flow rampaging through his body, making his whole body numb.

At this time, Yi Yun had a feeling that his whole body was full of strength and he wanted to vent it.

He wants to go up the mountain to cultivate, and he can't wait!

Finally waited until dawn, after the people from the daytime class came to replace Yi Yun, Yi Yun went straight to the back mountain, he first trotted slowly to the pass of the back mountain, and after seeing that there was no one around, Yi Yun began to run!

He is like a vigorous antelope, jumping at will, that is, a distance of five or six meters.

Three-meter-high rock, one step up, five-meter-high tree, cross from it!

Yi Yun is simply not running, but flying close to the ground! The terrain in the mountains and forests is so complicated, but under Yi Yun's keen five senses and reactions, any terrain is not an obstacle for Yi Yun.

He ran to the top of the hill in one go, climbed over a hill, came to the back slope, crossed a ravine, and went to a mountain further back.

During this period, Yi Yun did not have a break, he kept breathing at a frequency as he walked, not too fast, but extremely deep, and his heartbeat was also a constant frequency, not fast, but very powerful!

It wasn't until half an hour that Yi Yun stopped, and after running for such a long time, his face was still not red, and his heart was not beating! Running was also a way of cultivation, and after Yi Yun ran like this, he felt his whole body drenched.

This place is already the farthest safe place from the village, and if it is farther away, it will be beyond the shelter of the spiritual land, and it is possible to encounter giant beasts and desolate beasts.

With Yi Yun's current strength, he will definitely die when he encounters a desolate beast.

The vegetation on this mountain is not abundant, and in some places there are bare black rocks.

This is black iron rock, black iron rock is as heavy as steel, and the strength is several times that of ordinary rock, even if it is a green pine that can break through the rock, there is no way to grow seedlings from the black iron rock.

The place where Yi Yun stood was a flat land under the cliff, with a radius of ten zhang.

And on the top of the mountain cliff, there is a waterfall that is like a trick down, countless water splashes spread out in the sky, and the mist reflects the rainbow, this kind of scenery, placed on the earth, can definitely be regarded as an attractive tourist attraction.

The waterfall is not wide, but the drop is very large, more than 100 meters. The frantic crash of the water crashed down, rumbling and could be heard miles away.

This cultivation location was chosen by Yi Yun before, and the reason was because of this mountain spring and waterfall.

Yi Yun took a deep breath, the energy of his whole body flowed, and his penance began again.

In the empty mountains and wilderness, there is no one within a radius of dozens of miles, and Yi Yun practices "Dragon Muscle and Tiger Bone Boxing" with one move.

On the back mountain of the Lian clan, the most important thing is a big stone, and Yi Yun specially found a piece of black iron rock with a flat surface.

Yi Yun stood in front of this black iron rock and smashed it into the black iron rock with one punch!

How could a fist of flesh and blood smash through the black iron rock that even a green pine could not grow seedlings?

Yi Yun gritted his teeth, one, two, and three punches...... Ten punches, twenty punches!

Give it your all!

In the first few punches, Yi Yun just made his fists dark and blue, and the pain pierced his heart, and later, the fists were dripping with blood, and finally, the flesh and blood of the fists flew sideways, and the joints of the bones clicked.

Ten fingers connected to the heart, this pain is simply indescribable.

But Yi Yun gritted his teeth and insisted, his face was covered with sweat, his lips were pale, and his face was bloodless!

It wasn't until there was not much flesh and skin on the surface of the fist, and even the white bones could be faintly seen, that Yi Yun stopped.

Then, he began to kick the big stone with his legs again, kicking until his legs were so blue that he could barely stand, and after a little rest, Yi Yun began to hit with his shoulders and smash with his back!

Yi Yun used all the places that could be used in his body, but after all, he couldn't resist this piece of black iron rock, and he was already covered in bruises.

Pain!

Yi Yun was lying on the ground, his whole body had no strength at all, and his vision was blurred a lot.

He held his breath and began to follow the mantra and mental method recorded in the "Dragon Muscle and Tiger Bone Fist" to operate the energy in his body.

This is a fundamentally masochistic cultivation method, and Yi Yun didn't dare to use it before.

But just a few hours ago, Yi Yun devoured the energy of the cold python bones to his heart's content.

The energy contained in the desolate bones is called the power of the desolate, which is a great tonic for martial cultivators!

Compared to the power of the wilderness, the medicinal power of the herbs produced in the Lian's Medicine Mountain is somewhat insignificant.

Even the hundred-year-old herbs are much worse.

With the support of this desolate power, Yi Yun dared to carry out this almost masochistic exercise.

This practice method is the method of refining bones recorded in the Dragon Muscle Tiger Bone Fist "Tiger Claw Split Stone".

Beating the muscles and bones with rocks is a painful and difficult process, and it is impossible to persevere without strong perseverance.

Even if you have perseverance, you need to have the resources to support it.

Otherwise, if the injury is like this, let alone refining bones, it would be good not to leave a disability.

Because of the limitation of resources, the Tiger Claw Splitting Stone move, the members of the Warrior Reserve Battalion did not dare to try it easily.

Those young heroes in the big family, they can eat good desolate beast meat and wash their bodies with desolate beast blood, so they can withstand such injuries.

The power of the wilderness was working rapidly in his body, Yi Yun felt the wound itching, and he knew that his wound was healing.

The barren bones are really a good thing, and with the purification of amethyst, the speed at which this energy promotes the healing of his body is almost visible to the naked eye!

"Dragon Muscle and Tiger Bone Fist" refining bones, the power of the wilderness to make wounds heal, such a cultivation method is like striking iron.

The "hundred steel" used to forge swords is to fold and forge the steel repeatedly, and always make a peerless sword!

Yi Yun's current cultivation is similar to forging a sword.

He treats his body as steel, and the black iron rock as an anvil, forging and cultivating again and again!

After resting for three hours, Yi Yun felt that he had almost recovered, and the wounds on his hands had already scabbed, and he didn't affect his movements much.

Yi Yun wrapped the wound with a coarse cloth, and without saying a word, he plunged into the mountain spring and waterfall!

"Whoa!"

The waterfall pounded into the body like a hammer!

And under the waterfall, there is a deep pool!

This deep pool has been hit by the waterfall for many years, I don't know how deep it is, from the ground, this deep pool is green, like a piece of jade, bottomless.

This was the deepest waterhole Yi Yun could find near the Lian clan.

What Yi Yun cultivated this time was the move in the "Dragon Muscle and Tiger Bone Fist" - "Dragon Dance Wang Yang"!

In fact, the real "Dragon Dance Wangyang" is not cultivated in this way, the ocean is the sea, Yi Yun has no sea in the great wilderness, only waterfalls and deep pools.

"Dragon Dance in the Ocean" is a method of cultivating internal organs.

In fact, the more he cultivated this set of "Dragon Muscle and Tiger Bone Fist", the more Yi Yun felt the ingenuity of "Dragon Muscle and Tiger Bone Fist".

The strength and speed of a martial artist are easy to cultivate, but the tendons, bones, and internal organs are all in the body, and it is not easy to train them.

In the "Dragon Tendon and Tiger Bone Boxing", the warrior cultivates the tendons, pulls the tendons with the "Tiger Descending the Mountain", plucks the bowstring, and makes the tendons stronger and stronger.

Cultivating bones, using the "Tiger Claw Split Stone", the bones are repeatedly forged like steel.

As for the cultivation of internal organs, it is even more difficult, internal organs are no better than bones and tendons, and martial artists cannot actively control internal organs to move, so it is not easy to cultivate.

Therefore, the creator of "Dragon Muscle and Tiger Bone Fist" came up with the trick of "Dragon Dance Wang Yang".

"Dragon Dance in the Ocean" requires cultivators to jump into the sea and dive down to a depth of one or two hundred meters in one breath, and the pressure of the sea water below 100 meters is terrifying, which can crush all the eardrums and internal organs of a person to burst!

Water pressure can indiscriminately act on the internal organs of the person, and long-term bearing of this huge pressure can make the internal organs become more tenacious!

Yi Yun took a deep breath, hugged a big stone, and jumped directly into the depths of the pool!
