At this moment, the time has entered the middle of the night, and the moonlight outside the cave spreads on the earth, but there is no light in the cave.

Bursts of collision sounds kept coming out of the cave, and the speed of the collision was not so rapid, but it gave people the feeling that there was no outbreak of the huge power that contained it, and it was extremely dull!

Ye Yun had no time to look at the nearby demon stone apes who were fighting, carrying his twin swords on his back, and rushed to the twenty-three times gravity area in one go.

In an instant, the pressure of thousands of catties suddenly squeezed the whole body, and the blood vessels, internal organs, bones, and muscles were everywhere.

Although the pressure is heavy, it is not as breathless and uncomfortable as I imagined. The body can still move, but at a much slower pace.

Ye Yun decided to take another step forward, because twenty-three times the gravity was not much different from twenty-one times the gravity for him now.

Looking back at the entrance of the cave, where he was standing at the moment was about fifty meters away. The gravitational force increases by the length of the hole.

According to this calculation, then the next step is subject to twenty-five times the force of gravity.

"Twenty-five times?" Ye Yun smiled at the corner of his mouth, he could still withstand this gravity.

Without the previous step by step temptation, the body moved, and the whole body directly left the distance of fifty meters away.

"Uh-huh!"

A heavy muffled sound rolled from Ye Yun's throat, and then the sound of two bodies kneeling on the ground was heard.

"Click...... Click......"

I saw that the ground where I knelt suddenly cracked, and the fine lines were there.

"How can this be?" Ye Yun held his hands on the ground in disbelief, and for a moment, he felt that his head was as heavy as a boulder. Can't lift it up at all.

The two swords behind him were like Mount Tai pressing at this moment. If it weren't for these ten days of penance. I'm afraid that my body has been crushed.

"How can gravity be so great! Not at all twenty-five times the gravity. Ye Yun scolded in his heart. "To be able to overwhelm yourself in an instant, I'm afraid that it's more than thirty times!"

Thirty times the weight of the sword has already reached two thousand catties, and the strength of the muscles and bones has reached the limit, and it is simply unable to support such a weight.

"Boom!"

The life energy in the spirit rolled out like a flood, and in an instant, the light of Ye Yun's body bloomed, and the entire dark cave was illuminated transparently.

With the infusion of life energy, Ye Yun felt that the pressure on his body had plummeted by more than half in an instant, and he did not rush forward with this power. Instead, he retreated and slowly walked out of the cave.

"Boss, what's wrong?" Seeing Ye Yun come out so quickly, the little fart couldn't help but ask suspiciously.

"It's okay, I just feel that carrying two swords on my back can exercise my body's endurance. But at this moment, my physical strength has reached a bottleneck, and I can't withstand the gravity of two swords at thirty times the gravity

It doesn't make much sense to continue cultivating with two swords on your back," Ye Yundao said.

Ye Yun's approach was correct, at this moment, his body could only withstand more than two thousand catties of pressure from the outside world. If you add a few hundred pounds, I am afraid that the body will be quickly crushed.

So what he has to do now is to throw away the pressure from the outside world and let his body only bear the pressure brought by himself. It is important to know that these two pressures are not the same.

External pressure can only exercise the strength and resilience of muscles and bones. hardness, but there are many things that cannot be exercised, such as the strength of internal organs, etc.

However, the pressure of only being on oneself can bring out a lot of inner potential, and crucially, it is not easy to be crushed by gravity.

Unloading the two swords and not making any more adjustments, Ye Yun's whole person rushed directly into the cave.

Gravity is nineteen times ...... Twenty-one times ...... Twenty-five times ......

Unloading more than 2,000 catties of weight, Ye Yun felt relieved, even under twenty-five times the gravity, he was like a fish in the water.

Step out!

Thirty times the gravity collapsed, and a muffled snort rolled out of Ye Yun's throat again.

This time his body did not fall to his knees, but stood in place like a javelin, but his internal organs were extremely uncomfortable.

"I don't know if this will allow me to break through the limit......" The corners of Ye Yun's mouth showed an arc, and a trace of ruthlessness flashed in his eyes.

Suddenly, I saw Ye Yun's originally quiet figure begin to dance, his movements were slow and heavy, but not jerky.

As the body danced for a longer time, the air currents in the pitch-black hole poured into Ye Yun's body in a regular manner.

"Crackling ......"

A crisp sound burst in Ye Yun's body, but this burst sound could only be heard by Ye Yun himself.

The frequency of the popping sound continued to increase, and the speed at which the external air flow poured into Ye Yun's body became faster and faster.

At this moment, Ye Yun's face was already very hideous, and every cell in his body was trembling, but if someone was here, they would be surprised to find that Ye Yun's dancing body was getting faster and faster, and every movement was very crisp and smooth!

"I really didn't expect that the effect of cultivating the fourth-level boxing technique under such pressure would be so strong......" A painful voice came out of Ye Yun's mouth.

That's right, Ye Yun is not dancing indiscriminately, but dancing the Four Seasons Fist Technique.

Summer has long passed, and early autumn has been lost to late autumn, and the boxing technique that Ye Yun is practicing at the moment is 'autumn boxing'

The air flow in autumn is the most piercing, each air flow enters Ye Yun's body, and Ye Yun only feels that his whole body is pierced from the inside to the outside as if he has been pierced by thorns.

It's both painful and irritating!

But this kind of numbness after stimulation, as well as a little bit of rejuvenation, made Ye Yun enjoy it very much.

Time flies little by little......

Ye Yun cultivated this Four Seasons Fist Method under thirty times the gravity and tempered his body!

One day......

Two days......

Five-day ......

Inside the dark cave, except for some crashing sounds, it was so calm.

For five days, Ye Yun had been practicing the Four Seasons Fist Technique, and his body had become numb and unconscious, and he had even forgotten how to breathe.

It's just a mechanical boxing practice, and one after another air currents pour into the body, and there is no stinging and trembling at the beginning......

Click...... Click......

It's like a thousand-year-old iceberg, so cold that it cracks out of a crack.

Ye Yun, who was in numbness, only felt that his body was about to shatter, as if he was no longer a person, but an ice sculpture.

At this time, there seemed to be a crack in the chest of this ice sculpture, and along this crack path began to swim all over the body.

"Click!!!!

"Pounds!!!!

Pulling a hair and moving his whole body, just for a moment, Ye Yun only felt that his body had been scattered Ling Ling!

It seemed that under the traction of some kind of force, Ye Yun sat cross-legged on the ground, closed his eyes and rested!

Suddenly, a slight roar came from Ye Yun's body,

"Boom !!!"

It was as if the earth, which had been dry for a hundred years, suddenly poured out of the ground and flooded the earth.

Ye Yun's almost unconscious body, the cells that were squeezed to the limit of the Dao, exploded with countless energies like no pole Tailai.

At this moment, every cell in Ye Yun's body was sucking the sudden energy.

Ye Yun, who was in numbness, came to his senses and felt the transformation of his body breaking through the limit, which made him enjoy it very much, as if there was nothing more wonderful in the world.

For a full day, Ye Yun's body was in recovery.

Ye Yun, who was sitting cross-legged on the ground, obviously felt that his muscles were full of explosive power, and he believed that this was not an illusion!

Slowly standing up, I only heard the crackling of bones all over my body.

Relax with a slight movement of your body......

"Strange! How could my body be so relaxed. Ye Yun threw a few punches in disbelief.

Under this thirty times the gravity, the speed of his punch was as if it were hit without gravity.

"This ...... This ......" Ye Yun clenched his fists in disbelief.

As if he didn't believe these facts, Ye Yun began to beat in place, his body was still bearing gravity, but this gravity didn't seem to be thirty times the gravity at all, it seemed to be only five times.

I didn't feel the slightest discomfort in my internal organs, and even my breathing was very easy.

"Hahahaha......"

Ye Yun finally couldn't control his happy feelings, and laughed heartily......

"I really didn't expect that this breakthrough in physical strength would actually increase my strength so much......" Ye Yun still can't believe that this qiē is true! (To be continued......)
