He didn't have any burden on his body, but he was like carrying a mountain, every step he took was lifting and falling, it was like he was doing his best, and every muscle in his body seemed to be pulled by some kind of force, constantly trembling.

In fact, it does!

At this moment, Li Dahu, every cell, every inch of muscle, and every inch of bone is bearing five times the gravity of the earth!

Five-fold gravity is not simply five times the weight of the force, but the whole body, including muscles, bones, blood, internal organs, and even the cerebral spinal cord, etc., must bear the weight of five times the gravity of the earth.

This force is comprehensive, there are no dead ends, there is no possibility of tricks at all, only gradual adaptation.

Even if Li Dahu's physical fitness has reached more than ten times that of ordinary people, he does not dare to be careless, and can only improve his gravity step by step, from twice as much at the beginning, and gradually increase to five times as much as now.

"You can go on!"

After running for a few laps in a row, Li Dahu felt that he had adapted to five times the gravity, and once again used the 'Heaven and Earth Control' to slowly increase the gravity to six times!

Then, there was another flurry of acclimatization and jogging.

Six, seven, eight......

As the gravity became more and more intense, the pressure on Li Dahu also increased, every muscle in his body was moaning/groaning, and when the gravity reached ten times, he couldn't even run, he couldn't even stand steadily, and he could fall at any time!

"Can't go down!"

Li Dahu was covered in sweat at this time, and there was a trace of fishy blood in the sweat, which was the 'impurity' discharged from the body after stimulating the potential in a short period of time.

Under the weight of ten times the gravity, he didn't even have the strength to blink, and he was fighting with all his heart.

Hellish tempering, under the huge pressure of external forces, the potential in Li Dahu's body that has not been completely stimulated has been squeezed out little by little, and every time he feels that he can't hold on, a new force will always emerge and pull him back from the brink of collapse.

Time passes between this coming and going.

Finally, Li Dahu began to move, and against ten times the gravity, he took steps cautiously, like a baby who had just learned to walk, staggering, and walking very carefully.

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

Slowly, Li Dahu's movements became more and more fluid, and his steps no longer wavered, but became steady.

After more than an hour, the hidden power in his body gradually activated, completely wiped out the discomfort caused by ten times the gravity, and he also began to jog.

It is said to be jogging, but in fact, at the beginning it was more like a walk, unhurried.

However, with the passage of time, after Li Dahu adapted to ten times the gravity, his speed began to gradually increase, from walking, to brisk walking, and finally, it really became jogging.

"Ten times, a lot of progress compared to before, but this is already the limit, no matter how big it is, it won't play the role of exercise, but will crush your body to collapse."

Feeling the strong pressure in his body, Li Dahu couldn't help but think of the tragic situation in his mind after he was in a hurry and increased gravity several times at once, and his eyes couldn't help but show a trace of palpitations.

That time, he died a terrible death, not in battle with the 'Nightmare', but was crushed into a puddle of mud, and to this day, he can't forget the pain.

"How long have I been here? One week? Or a month? Or even longer? ”

While running, a question appeared in Li Dahu's heart.

In this unknown space, there is no night, and there is no accurate timekeeping tool, and he will barely remember the time at the beginning, but as he is 'killed' again and again, he also gives up other irrelevant little things and devotes himself to the training.

A hundred chances to resurrect from the dead, plus the one he 'committed suicide', by now he has consumed twelve.

It's not that he wants to die, but he has to die!

Li Dahu originally thought that he could temper his body all the time, and after he reached the control of his own power like a 'Demon Nightmare', he would attack it in one fell swoop. Defeat, then complete the Progression.

But reality gave him a hard slap in the face!

For the first time, he tempered frantically every day, until he felt that there was no room for improvement, and then he fought against the 'Nightmare'.

However, in that fight, he only held two moves and was killed in seconds.

When he was resurrected, he found that his physique, which had reached the limit, had actually loosened again, and then he tempered himself again.

Then, when he felt that he had reached his limit again, he was still killed by the 'Nightmare' in five moves.

After that, as before, the limit of his physique was loosened again, so ......

Until now, Li Dahu has become accustomed to it, every time he reaches the limit, he will take the initiative to 'find death', and then begin to continue to temper himself.

Twelve deaths, in exchange for which he can now fight against the 'Nightmare' for nearly forty moves.

Although the progress in this is very small, it does exist, according to Li Dahu's own estimate, in his current state, against himself before he started the advanced task, there are three layers of possibility to win or even kill!

The three-layer probability seems to be inconspicuous, but the real actual change in combat power is very huge. The difference in the physical body is not the key, what really matters is the control and use of one's own power.

If he was able to hit 100 damage with one point of profit before, then now he can hit 110, 120 or even higher with one point of strength!

"It's a pity...... The progress is still not fast enough, compared to the 'Nightmare', I am now a toddler at best, there is no comparison at all! ”

Such a little progress may make Li Dahu a little excited in normal times, but here, in front of the more perverted 'Demon Nightmare', his little progress can't be put on the table at all!

"Feeling...... It's reached the limit again, and it looks like we're going to have to die again! ”

The familiar feeling resurfaced again, and Li Dahu's face became ugly.

Although he had 'died' more than a dozen times, every time, he felt his scalp tingle, and he couldn't forget the feeling of being pitch black, seeing nothing, not touching, and not feeling!

However, hesitation is not his temper, and, moreover, here he has no choice.

After resting and adjusting his state, Li Dahu once again stood in front of the 'Demon Nightmare'.

"This time, see how long I can last!"

He whispered to himself, and then his eyes froze, and a strong killing intent surged towards the 'Demon Nightmare'.

The next moment, the scarlet eyes of the 'Demon Nightmare' flashed like a dead thing, and it rushed over with a brush, leaving even a few afterimages along the way, slowly disappearing.

Although he had strengthened it a few times, Li Dahu still didn't have the confidence to go toe-to-toe with the 'Nightmare', so when the opponent's fist was about to hit him, he dodged and slashed at the opponent's neck with a palm.

The 'Demon Nightmare' reacted extremely quickly, as if it had predicted his attack, and when Li Dahu's hand was raised, it reacted in advance.

With just a slight sideways, Li Dahu's attack was dodged.

Not only that, but while dodging, the left leg of the 'Demon Nightmare' was like a steel whip, and it whipped angrily, whistling with a violent wind, which was very terrifying.

After such a period of hell training, Li Dahu was naturally not as 'vulnerable' as he was at the beginning, and when the 'Nightmare' attack came, he swept over and interrupted the opponent's attack.

"Come again!"

He roared and attacked again.

'Demon Nightmare' was silent, but every move was a lethal attack, and Li Dahu's voice was quite loud, but it couldn't change the ending of him being pressed and beaten the whole time.

His attack...... Hardly, all the time defending and dodging!

10 moves, 20 moves, 30 moves......

Finally, when the two sides exchanged fifty moves, Li Dahu couldn't react, and was hit in the head by a punch from the 'Nightmare', and 'died' again.

After a while, the 'resurrected' Li Dahu reappeared.

Although there was still the fear of death in his eyes, this time he didn't show too much, but stared at the 'Nightmare', and there was a flash of light in his eyes.

"That's ...... so"
