As for the gravity of the earth, Ye Yun is completely ignorant.

Walking into the entrance of the cave that was nearly ten meters high, looking inside, Ye Yun found that the cave was not as dark as he imagined, and the faint light could still see a qiē inside the cave.

However, the scene in the cave made Ye Yun very disappointed, the entire cave area was nearly a thousand square meters, and it was extremely empty, except for some scattered stones and more than a dozen demon stone apes who were fighting.

"Cut! This is also called a magic array?" Ye Yun smiled disdainfully.

Take a step forward, there is no enchantment, and it is easy to walk into the cave.

"What's the matter?" Ye Yun's eyes suddenly became solemn, it was his left foot that had just stepped out, according to the step he had taken in the past, it was close to seventy centimeters, but at this moment, his left foot had just stepped out of about thirty centimeters, and his left foot seemed to be ten times heavier in an instant, and it was heavily attached to the ground, no!

"Is this gravity?" Ye Yun seemed to understand.

At this moment, he looked at the dozen or so demon stone apes that were fighting in the cave, and found that their movements were extremely slow, and the speed of each punch could be easily dodged even by a person without cultivation.

The speed of the body movement is extremely slow, as if it is moving with a mountain on its back!

"What a gravity!" Ye Yun's eyes were filled with fiery light. Kick the ground with your right foot and quickly enter the hole.

"Uh-huh!" A muffled snort rolled out of Ye Yun's chest, and Ye Yun, who had just stepped into the cave, almost fell to his knees on his knees.

He felt that his body had become dozens of times heavier in an instant, of course, this weight was nothing to Ye Yun, whose strength had reached that of a Great Dou Master.

But it's not just the thighs and arms that make the body heavier. Even their own internal organs. The weight of the heart, liver, intestines and lungs increases instantaneously.

At this moment, Ye Yun only felt his blood churning. Breathlessness and extreme discomfort.

Ye Yun stood in place and took a deep breath slowly, calming the qi and blood in his body, knowing that he was breathing, Ye Yun realized that he didn't know whether the weight of the air in the cave had increased or his respiratory system had become sluggish, and it was not so easy to take a deep breath.

Ye Yun's body was not so fragile, and the cultivation of the Four Seasons Fist Method was not only to enhance the strength of the bones and muscles, but also to enhance the internal organs.

In less than ten minutes, Ye Yun adapted to the gravity at this moment.

But the movement of the body is not so easy. Ye Yun began to walk towards the depths of the cave step by step.

With each step, Ye Yun clearly felt that the weight of his body had increased slightly, but it was not very obvious.

One-step, two-step, three-step......

Ye Yun silently counted the steps he had taken in his heart, and when he took fifteen steps, Ye Yun clearly felt that the gravity of the ground on the body increased significantly. Fifteen steps is roughly equivalent to a distance of ten meters.

If the previous gravity was fifteen times, then the gravity at this moment should be seventeen times. This gravity is only an estimate of the leaf clouds.

Seventeen times the gravity is no different from fifteen times for Ye Yun.

He continued to walk forward, and when he had taken about fifteen steps, the gravity increased significantly again, and seemed to increase from seventeen times the force of gravity to nineteen.

This time, Ye Yun probably understood that gravity was less than ten meters in a section. A little bit incremental.

At the other end of the cave, there is a staircase. The staircase does not lead to the top, but to the bottom.

The staircase leading to the bottom was about three hundred meters away from Ye Yun.

"If you want to enter the second layer like this, wouldn't you have to bear seventy or eighty times the gravity" Ye Yun calculated in his heart, and the calculated takeover was still acceptable to Ye Yun.

Nineteen times the gravity, Ye Yun barely adapted. Ten meters again. As Ye Yun estimated, the gravity of nineteen times rose directly to twenty-one times.

Ye Yun stopped, and he found that his internal organs were uncomfortable again, and it became difficult to breathe. The six-fold increase in gravity left him with a small bottleneck.

Stopping does not mean resting, the three spirit beads in the spirit rotated slightly, and a trace of life energy flowed throughout the body, Ye Yun suddenly felt comfortable all over his body, and the pressure on his whole body was instantly reduced a little.

"No!" Ye Yun immediately stopped the infusion of life energy, indeed, with life energy, the body can be more relaxed, but in this way, he will not be able to know the limit of the body.

"It's better to wait for your body to reach its limit and use your life energy," Ye Yun thought to himself.

In order to make his body adapt to twenty-one times the gravity faster, Ye Yun began to do some basic movements rhythmically.

Squats, jumps, leg swings, punches, handstands......

The action is simple, but Ye Yun is not so simple to do, and the energy consumed by each action is almost twenty-one times that of without gravity.

Suddenly, Ye Yun realized a problem, in fact, the gravity he was bearing was not only the gravity of his own body, you must know that he also carried two swords behind him.

"The long sword weighs fifty pounds in the dark night, and the dragon sword weighs nearly twenty pounds, and the two add up to seventy pounds, and when you add your body that weighs about one hundred pounds, it is a total of one hundred and seventy pounds!

In the case of twenty-one times the gravity, one hundred and seventy catties soared directly to the weight of three thousand five hundred catties.

"Oh my God!" Thinking of this, Ye Yun himself felt scared, three thousand five hundred catties?

Ye Yun's calculation was indeed not wrong, but he miscalculated a little.

Just imagine, if one person carries a hundred pounds of clothes on his back, and another person wears a hundred pounds of clothes on his body, the pressure on the two people is completely different.

The former is under almost twice as much pressure as the latter, because the latter spreads the pressure out.

At this moment, Ye Yun seemed to be bearing three thousand five hundred catties of gravity, but in fact he was only bearing one thousand seven hundred catties. But this number is already very scary, you must know that Ye Yun's age is not yet eleven years old.

The main reason for doing different basic movements is to adapt every musculoskeletal part of the body to twenty times the force of gravity.

Time passed little by little, half an hour had been lost, Ye Yun already felt that his body was about to be exhausted, his muscles were sore, his brain was dizzy due to lack of oxygen.

Stop moving, sit cross-legged on the ground, the life energy flows all over the body, and every cell in the body is not frantically sucking life energy.

In fifteen minutes, the cells of the whole body were moisturized and saturated, and he clenched his fists gently, Ye Yun obviously felt that his strength had increased, and his body strength was even more fleshy and still hard.

A cycle of recovery does not mean that his body has adapted to twenty-one times the pressure, his internal organs are still heavy and uncomfortable, and it is still difficult to breathe, but Ye Yun knows that the difficulty is being reduced little by little.

Squats, jumps, runs, handstands...... Body lì depletion...... Cross-kneeled fù......

Ye Yun kept repeating the cycle like a machine.

As the day passed, the life energy in the spirit was exhausted, and the stomach was extremely hungry, and this consumption was too great. Bearing a weight of 1,700 pounds and constantly exercising, anyone will not be able to stand it.

It's already the next morning, and the little fart has already prepared the meal.

After Ye Yun had a big meal, he sat cross-legged at the door of the cave to recover his life energy.

It's not that Ye Yun doesn't have the ability to absorb the life energy of the outside world in the cave, but because the cave is almost soaked with earth elements, and the life energy is extremely thin.

After meditating for two hours, Ye Yun entered the cave again, and rushed directly to the twenty-one times pressure area in one breath. It began to be hard again.

Time passed.

Two days......

Three days......

Half a month......

"Little fart...... Food...... Food...... Is there anything to eat!" Ye Yun was naked and breathing heavily, his eyes were sunken, and his body was covered with beads of sweat and ran out of the cave, shouting hungrily.

"Boss, eat!" The little fart hurriedly brought a roasted monster and a bucket of clear spring.

Ye Yun devoured it, and in less than five minutes, half of the demonic beast had already been swallowed, and it was ...... Gollum ...... Poured a few mouthfuls of clear water.

"No, I'm tired!" Ye Yun shouted, but he didn't rest.

After eating, he wiped his mouth and began to practice internal boxing.

Neijiaquan has the magical effects of calming the mind, cultivating the body, gathering spirits, etc., and with continuous practice, Ye Yun is more and more discovering the mysteries of Neijiaquan.

It's been half a month, and Ye Yun hasn't closed his eyes once. Sleepy, practice inner boxing. When you are tired, practice "Soul Refining Decision". Hungry, eat. Thirsty, drink. There was no rest.

After fifteen days of penance, Ye Yun's physical strength has changed drastically, and his skin has become a little whiter, and that is because he sweated too much. The lines of the muscles are more defined.

Three hours of boxing, this is the longest time that Ye Yun has practiced in fifteen days, the warmth of the inner boxing, the spiritual power is extremely clear, and the life energy has also reached the peak state.

The reason why Ye Yun did this today was because he was going to take the next step, twenty-three times the gravity.

After a slight adjustment, Ye Yun rushed into the cave with his dual swords on his back. (To be continued......)
