There are a total of 639 muscles in the human body, which are composed of about 6 billion muscle fibers, and if humans can fully use each muscle, the sum of their whole body strength can reach a huge force of 25 tons, and each muscle fiber of muscle tissue can produce a force of about 0.3 micronewtons, and each muscle per square centimeter can produce a force of about 100 newtons (about 10 kilograms).

If every muscle fiber is utilized, then theoretically, the maximum punch power of a person is definitely more than a hundred tons!

This is the power that people can theoretically play, which is converted to 200,000 catties, not to mention low martial arts, even the boss of the martial arts world is definitely a life on the street if he eats a punch, of course, such a punch is swung out by ordinary people, and it must not be able to live, not to mention the reaction force, just the genetic collapse, maybe the fist is half swung, and the person will die.

And Lin Xin's situation at this time was similar.

Doubling the speed of sound, why Lin Xin has not been used for a long time, is because the mortal body will cause irreversible damage to the body after entering this state, and after the double speed of sound is turned on, it will be a proper dead end.

But now Lin Xin obviously can't care so much.

"Come on, let me see...... Are you in this world...... Really invincible. ”

Lin Xin's voice came out of the blood mist intermittently, like a radio with a bad signal.

For a while, a large cloud of qi and blood burst out from Lin Xin's skin, merging with the outer layer of blood mist, becoming thicker, Lin Xin's appearance was completely invisible, and from a distance, there was only a ball of blood.

'Click!! ’

A flash of thunder flashed.

Emperor Zun's face couldn't help but become heavy, he didn't speak, his body moved instantly, and he couldn't tell whether it was thunder or lightning or a fist under the night sky, but in an instant, the blood-stained fist fell on the middle of Lin Xin's chest.

The fist seemed to cross the infinite distance at once, and it actually burst the blood mist.

'Bang!! ’

Lin Xin's body shook, and at the same time, a palm fell with a bang, knocking the emperor into the air, and after the speed was increased to a certain level, a little bit of strength would become very terrifying, not to mention Lin Xin's already inhuman strength.

With a low snort, Lin Xin instantly disappeared in place, clenched his hands into fists, and slammed into the emperor.

'Boom!! ’

Emperor Zun raised his hands and waved wildly, in the collision that was invisible to the naked eye, it brought a continuous sound of air explosions, and for a while, he could actually compete with Lin Xin, who burst out at twice the speed of sound.

No, it's not completely comparable, in the collision again and again, the emperor's flawless hands finally began to crack, flesh and blood flew, and even the crystal clear white bones in them could be faintly seen.

In the fight, Lin Xin also used a variety of attacks at the beginning, grabbing, pointing, punching, holding, colliding, and so on a variety of different martial arts methods, but in the end, Lin Xin found that skills are useless to Emperor Zun at all, no matter how fancy and powerful skills are in the hands of Emperor Zun, only the most direct attack and extreme speed can force Emperor Zun to be tough with you, not to talk about any skills.

After a long time, Lin Xin and Emperor Zun had completely left the original battlefield and came to the forest.

Lei Qian's figure just appeared in embarrassment, and she couldn't see anyone, but her keen intuition kept reminding her of the coming of death, desperately escaping, and her face couldn't help but show a trace of despair.

'Boom! ’

didn't even have a chance to resist, Lei Qian was whipped away by the invisible fist, a large number of trees were broken, and when it stopped, Lei Qian had been completely broken into two pieces and turned into flesh and blood.

Emperor Zun was covered in blood, and it seemed that the injury was not light, and the most critical pair of fists became bloody and blurred, without skin, and deep and exposed.

And the blood mist that shrouded Lin Xin was more than one layer less, revealing Lin Xin's thin figure inside, even thinner than usual, as if a gust of wind could blow it down.

"Dead !!"

Compared with the thinness of his body, Lin Xin's eyes have become brighter than ever, and the huge aura exuded by the whole person is even several times or even more than ten times more terrifying than at the beginning.

The whole person disappeared in place, and Lin Xin's right hand stretched out and grabbed the emperor's head fiercely.

'Bang!! ’

In a dull loud noise.

Skinny arms and bloody fists collided together.

Lin Xin's face remained unchanged, and his left hand was grabbed violently, bringing five terrifying winds, as if they were alive in the palm of his hand, spinning and roaring.

Combined with the national art of this world, Tiangang has undoubtedly become more terrifying.

Lin Xin's left hand seemed to turn into five violent swimming dragons, swinging his body and rushing towards the emperor with a huge terrifying power and penetrating power.

At the same time, Emperor Zun raised his right knee and faced Lin Xin's left hand.

Another bolt of lightning fell.

A terrifying wave of qi suddenly erupted between the two.

'Bang!! ’

Emperor Zun's whole person was directly beaten out for dozens of meters, smashed a large number of trees, and finally plunged into a mountain wall, and a large number of mountain rocks rolled down, almost burying him completely.

"That's absolute power."

Lin Xin coughed up blood, but his thin body stood in place, as huge and terrifying as a demon god.

Although the price of twice the speed of sound is very high, and she is even almost at the point of running out of oil now, she feels the life that has been cut off not far away, but fortunately, she finally killed the emperor.

Breathing a sigh of relief, a lot of past events have crossed through my mind, my father, mother and sister, although everything has been arranged in advance, but I always feel a little pity?

I remembered that my sister had said in her dream that she would not marry in the future, and that she would marry her as a bride, if she didn't die, I don't know if it would count.

While waiting for the end of his life, he thought about something unreliable.

'Drink!! ’

Suddenly, a golden light flashed in front of her, and the Void Emperor Zun appeared in front of him in an instant, holding a golden knife and slashing at her!
