Ji Chen came to the depths of the back mountain, unconsciously looked around, for the first time in eight years, he came to the depths of the back mountain, thick trees, messy grass and thorns, rotten dead leaves all over the ground, and countless beasts living in this mountain.

"This scale is comparable to the primeval forest we have there!" Ji Chen sighed incomparably, the growth scale of the flowers and trees here and the small grass and trees around are simply two worlds, here, Ji Chen seems to be able to smell the smell of wildness!

"Okay, then I'll start my plan to become stronger!" Ji Chen breathed in the fresh air and began to jog on the withered leaves.

The way of refining martial arts is all in one "refining" word, refining tendons, refining bones, refining skin, refining meat. Refining tendons is for the flexibility and sensitivity of the body, refining bones for the functions of the body, refining skin and refining meat for the explosiveness and resistance of the body, but all of these must be based on a good body that is complete and healthy, so that he can withstand that kind of exercise.

For Ji Chen, with his current physical development level and physical fitness, he can only do some basic training, originally because his nutrition can't keep up with the speed of physical development, but since Ji Chen got the mysterious stone, all problems are not a problem, and as soon as the problem of fatigue is solved, Ji Chen can carry out his physical fitness foundation lifting training without any scruples, so his top priority now is to exercise his physical fitness first, so he can carry out the later "body training" plan. The so-called basic training is generally used as the beginning of training, which is most suitable for Ji Chen's current state, which includes endurance training such as long-distance running and standing piles, which is to lay the foundation for "refining bones"; And now there is another kind of training that is also essential, that is, strength training, as an auxiliary exercise, is necessary for those who have poor muscle development, and there are people like Ji Chen.

In Ji Chen's original world, there was once a martial arts master who said such a sentence: Four taels can also be used to allocate a thousand catties...... Some people mistakenly think that they can really do this, but for hundreds of years no one has ever been able to do four or two thousand catties, and later in the master's codex people learned the reason, the master said that four or two thousand catties is not unrealizable, but to do four or two thousand catties There is also a premise that your own strength must surpass the thousand catties, in order to fight with force.

Ji Chen deeply understands this truth, in battle, if you want to use your strength, you must have extremely strong strength to support yourself to complete this technical work.

In a whistling sound, Ji Chen completed the first ten-kilometer run in these years, and in the previous life, he could only have the energy to complete such training when his whole body was well nourished, but ......

"Oops! How did I forget such an important thing!" Ji Chen patted his head, only to realize that he had taken a crooked path!

The so-called training is a kind of auxiliary training, this kind of exercise can only be persevered in strenuous exercise, even in setbacks, and finally win the victory, not only by the tenacious will, but also by the body's ability to resist, not only to constantly break through their own physical limits, but also to rely on the mental and spiritual breakthrough, so that it can be regarded as a real sense of exercise. Exercising without exhaustion is not considered exercise.

And now Ji Chen has made a one-sided mistake, in order not to get tired, he will one-sidedly pursue a breakthrough in the physical body and ignore the fatigue that should be borne psychologically.

But the next moment, Ji Chen immediately found a solution, Ji Chen found that the effect of the mysterious stone can only play a role when it comes into contact with **, so Ji Chen put it in his arms through a layer of clothes, his plan is like this,

After struggling to exercise for a period of time, within the range of what he could bear, Ji Chen continued to exercise, until he reached the point where he could no longer hold on, and then held the stone in his hand to relieve fatigue, so that he could continue his plan to become stronger.

Ji Chen's methods proved to be effective, and his endurance and physical strength improved greatly under his endless workouts.

Two months have passed.

This is a cliff, at this time a beast skin boy appeared in front of the cliff, this boy's hair has almost draped over his shoulders, his body is well-proportioned, his body is sharp and angular, and every muscle is not big, but from his every action, every cell of his contains explosive power, the boy walked to the cliff, walked two steps, looked at the mountain cliff, his temperament suddenly changed, snorted coldly, directly towards the mountain wall, and punched.

After this punch, the mountain wall did not move at all, but the boy's fist was exposed with blood, and the skin was broken, obviously it was Fang Cai's punch, the boy's strength did not have any reservations, and all the strength was punched, so this situation occurred.

This young man is Ji Chen, who came here two months ago, and in the past two months, Ji Chen has been practicing day and night, except for the time when he eats, washes and goes to the toilet, Ji Chen is all practicing, and here, Ji Chen almost eats wild meat, so his body is also a lot stronger.

"Wu Yidao, the regeneration of skin and flesh is the key, the skin is broken, the regenerated skin is a good skin, and then broken and regenerated, regenerated and broken, every time it is broken, its skin will be tenacious, this process is to train the skin, train the skin well, the body is a station, the five horses can not be separated, and a punch to break a hundred catties of boulders, it is all a random move!" Ji Chen muttered to himself

His fists went down, not stopping, punch after punch, fist after fist, fist after fist, not long after, his fists were stained with blood, and the blood did not stop, but even so, his fist did not stop.

"To practice skin, you must first start with your fists, and fists are one of the keys to a person's full-body attack!" Ji Chen snorted and continued!

The pain, he can naturally feel it, but in his eyes, these sufferings and pains are like drinking water, when he became the peak powerhouse, what can these sufferings be counted, and the tempering of physical suffering is easy for him!

This fist has passed, and it has been a tea time, Ji Chen's fists have been beaten beyond recognition, and he can't find any fists, and it can even be said that these fists are wrapped in bright red blood, and even the skin and flesh are not very obvious, and they are very blurry......

"The skin has fallen off...... If you continue to exercise today, it won't have any effect!" Ji Chen muttered to himself.

Enduring the pain, he frowned, but even though he smiled slightly, fortunately, there are still a lot of herbs on this mountain, Ji Chen has been familiar with this place in the past two months, and Ji Chen is also very clear about the location of some herbs that treat skin and flesh. When he was in that world, he naturally knew these, what kind of herbs, those herbs were still very effective in treating some epidermal injuries, and now he was honing his physical body, and this herb was naturally the best thing......

......

In the blink of an eye, it has been a year and a half since Ji Chen came to the depths of this back mountain where there are no human tracks, and it is now early summer, and there is gradually a scorching atmosphere in the forests of Dayan Mountain.

There is no trace of wind, the people in the mountains and forests are suffocating, "rustling~~" The sound of faint leaves dancing suddenly sounded in the silent mountain forest, and the sound became louder and louder.

"Whew!" a figure appeared in the distance of the mountain forest, the earth trembled slightly, and the figure had already passed a distance of more than ten zhang.

This is a young man who is only wearing shorts made of deerskin, leather shoes made of bear paws, ** upper body, his hair is covered all over his back, like a wild man, the most terrifying thing is that this young man is holding a terrible boulder that is a few sizes bigger than his whole body, the young man's arms are as thick as the thighs of an ordinary teenager, at this moment, the muscles on his arms are like steel bars, bursting out with terrible strength, and holding this boulder steadily.

At the same time, the young man's powerful legs are also thick and terrifying, and each leg pedals with a terrible strength of more than 10,000 catties, and his legs trample on the mountains and forests, causing a great earthquake to tremble, and he just rushes among the mountains and forests.

Whether he stepped on a dead branch or jumped over the dead wood on the ground, the young man who held such a boulder high was as nimble as an ape, and he could easily fly barefoot.

After a long time......

"Whew!" the young man, who looked like a prehistoric monster, finally stopped and threw the boulder at his side.

"Boom!" the boulder slammed into the side with an arc, and the branches and grass next to it were smashed and smashed into a large crater.

The boy walked over to the stone he had thrown away, stretched out his right hand, and gradually clenched his fist.

"Poof!"

A burst of air was generated out of thin air, and even within a radius of five meters of this place, a strong wind was generated out of thin air.

"Click......" An indiscernible sound came from the stone, "Smack!" In the next moment, a hole the size of a fist appeared in the place where the stone boy hit!

Clapped his hands and grinned, revealing his white teeth.

This young man is naturally Ji Chen, he came here a year ago, exercising day and night, even his height is rising again and again, at the age of ten, he already has the height of a twenty-year-old young man and such a Hercules-like body, and in the process of refining his skin, the waste skin on his body is constantly fading off by Ji Chen, and new skin is constantly growing, so the skin of his whole body is now as white as a woman, but under this kind of whiteness, Ji Chen's skin is like leather armor, and the general knife can't be cut at all!

"It's time to go back, that little guy should be in a hurry......" Speaking of this, a smile appeared on the corner of Ji Chen's mouth, and it could be seen that his relationship with this "little guy" should be not bad.

Ji Chen's running is not sluggish at all, on the contrary, he is very agile, like a cheetah, agile and powerful.

After a while, Ji Chen's figure was no longer visible here.
