Guo Xiu thought that he had experienced so much, and the slight pain that Nuwa said should not be taken to his heart, but it was not until the pain completely submerged him like a tide that he realized that his previous thoughts were simply too naïve!

Gradually rising from the depths of the bone marrow, Guo Xiu felt that every inch of his bones began to heat up. From the end of the toe bone to the top of the skull, every inch seemed to be burning, and Guo Xiu's ears even seemed to hear the sound of his own flesh and blood creaking.

Guo Xiu finally fully understands now, why Guan Yunchang's face has not changed when he scrapes his bones to heal his wounds, why it has been sung by the world to this day, with this kind of endurance, everyone has to scream and obey! And Guo Xiu's pain at this time is far better than scraping bones, that is just scraping on the surface of the bone with a blade, and Guo Xiu's feeling at this time is that every inch of his bones is put on the fire and roasted!

And that's just the beginning......

Then, from every part of the body's bones, there was a sharp pain that seemed to be broken and shattered. The scorching stinging pain, like a handful of red-hot steel needles being stuffed into the bones, kept stirring, and every time he stirred, Guo Xiu's nerves were pulled hard, and he almost couldn't help but break.

Guo Xiu couldn't even scream, because the throat bone basically didn't obey the call, and his throat seemed to have been stuffed into a soldering iron, and his muscles were locked and he couldn't say a word. I could only endure this feeling of hell for life, and then fainted in deep pain.

In this kind of torture that seemed to be torture, Guo Xiu was fainted and woken up by pain in that boundless dark space, and woke up and was fainted by pain. The sweat on my body was like rain, and soon the clothes around me were completely soaked! At this time, An Xiaoyu, who was guarding Guo Xiu's side in real life, quickly discovered that something was wrong, and after the investigation was fruitless, he immediately called Yao Muchan and asked him to see what Guo Xiu was all about.

"How?!"

As Yao Muchan retracted his body with a solemn face, An Xiaoyu on the side immediately asked nervously, looking at Guo Xiu's specific situation with concern. In just a few minutes since he called Yao Muchan over, the sheets under Guo Xiu's body have been changed four or five times, but the sweat on his body is still gurgling down like a faucet, and the new sheets will be wet again after a while.

But what puzzles An Xiaoyu the most is that in this case, people generally become weaker and weaker as they lose water in their bodies. But at this time, Guo Xiu in front of him not only did not feel that way, but his heart was beating more and more violently, and his face was becoming more and more radiant.

"Strange, really strange."

Even Jiazi Yao Muchan is knowledgeable, but at this moment, he is confused by Guo Xiu's current situation, to say that this is the sequelae caused by the injury, but there is no trace of vitality in his body at all. And the most bizarre thing is that Yao Muchan can obviously see that Guo Xiu's cultivation is steadily increasing, in such a short period of time, that realm has already stepped from the tendons to the wrong bones, and there is no intention of stopping at all, and it has been surging upward!

Is it possible that you still want to go up to the nourishment in one go?

"This kid is really a freak...... Yao Muchan couldn't help but gasp, turned his head to An Xiaoyu on the side and said: "Not only is this guy not doing anything, I'm afraid that after waking up, his strength will increase extraordinarily...... It's just that...... I've never seen a single exercise break through while sleeping......"

As he spoke, Yao Muchan's heart was confused again, and his eyes when he looked at Guo Xiu became more and more weird: This guy is really incomprehensible.

And at this moment, in Guo Xiu's body, with that pain, it was like a baptism scraping through Guo Xiu's body layer after layer. Guo Xiu's bones were undergoing an extremely astonishing transformation at this time. The internal structure of the bone became more and more compact in the process, and in the end, the hole in the middle of the bone could not be seen with the naked eye, and all the bones in the body seemed to have been re-materialized, and every inch and every centimeter exuded a jade-like luster.

Not only is it as hard as iron and stone, but it is also extremely tough, and the bone seams where all the bones meet have been thoroughly strengthened, and Guo Xiu can even drop his head at a hundred and eighty degrees as long as he wants to, and it is no big deal to twist it directly.

The strength gradually increases in this painful training, the early stage of the tendon, the middle stage of the tendon, and the late stage of the tendon...... Early stage of misalignment...... Misaligned mid-term!

With the passage of time, the final level of the Wrong Bone Stage was finally placed in front of Guo Xiu, that is, the vital dragon in the body - the backbone!

Since tonight's fish swimming method has advanced again, Guo Xiu has a great understanding of the power of the spine again. People who practice martial arts often say that luck starts in the dantian, and what is the support of the dantian qi sea? That is the spine, to be precise, the end of the spine, which is what we often call the lumbar spine.

In addition to the evolution of the brain, another aspect of human suffering from the evolution of four-legged reptiles to the current upright walking is the deterioration of the spine. Therefore, in the long period of evolution, although people are getting higher and higher, their hands and feet are getting weaker and weaker, which is the reason for the degeneration of the spine.

"The folding of snakes, the swimming of fish, the fight of beasts, the fluttering of birds, the movement and strength of all beasts and all things originate from the opening and closing of the backbone."

This is a passage in the theory of the spine, and the person who practices martial arts conforms to the natural phenomenon, imitates the spirits of animals and creates all kinds of boxing, and its fundamental purpose is to exercise the backbone, and finally make the whole body flexible and tremble, and practice the tentacles to inspire people and the round strength on the wall.

In the human body, there are 7 cervical vertebrae, 12 thoracic vertebrae, 5 lumbar vertebrae, a total of 24 sections, Taoist terminology called 24 floors, also called 12 pairs of chain locks. Therefore, in the boxing scriptures of Xingyi Boxing, there is such a passage for practicing the three-body pose: "Look at the Ding, abandon the navel, everywhere is unmovable, open the two or six chain locks, and a little spiritual light hangs on the eyebrows." ”

Therefore, in the cultivation of martial artists, people also call the final process of exercising the spine in this wrong bone stage as climbing the stairs and unlocking the lock!

Guo Xiu's brows furrowed slightly, and as the force forcibly raised by the system gradually shifted to his spine, although his will was still tormented by the pain, the instinctive caution in his heart still made his mood involuntarily raised.

This paragraph can be said to be the most critical section, if something goes wrong with the spine, then Guo Xiu's second half of his life will have to be a high paraplegic!

"Everybody's out there!"

Yao Muchan stretched out his hand and waved it, causing everyone to retreat, and he watched with a solemn face as Guo Xiu's back suddenly arched like a prawn, every bone on the spine trembled slightly, and everyone even heard the gurgling sound of the bones colliding.

Knowing that Guo Xiu was breaking through here, at this time, Hu Bo, Ji Yuxuan and others had all gathered over, and when they saw the scene in front of them, everyone couldn't help but speak, but no one made a single sound, for fear of disturbing Guo Xiu. They just stared at Guo Xiu's situation tightly, watching his every move.

Click-!

With a crisp explosion, the bones in Guo Xiu's neck suddenly seemed to fall off, and they were directly separated from the backbone, which suddenly made An Xiaoyu's heart twitch, and he involuntarily clenched his pink fist.

"Climb the stairs and unlock the ......"

Yao Muchan looked at Guo Xiu's state at this time, and couldn't help but murmur in a slight whisper. He was also extremely familiar with this scene in front of him, because he himself had experienced this process, the final stage of the wrong bone, the twenty-fourth floor twelve pairs of chain locks were completely opened, and finally when he could stretch and close freely and loosen, that was the time when the wrong bone was completed.

But when they climbed the stairs to unlock the lock, everyone else had been honed for many years, and then they were staggered one by one, but Guo Xiu in front of him was not like this at all!

Since the first section of the cervical vertebra was staggered, the next sound was like a string of firecrackers in Guo Xiu's body, and the crackling and crisp sound kept exploding. Yao Muchan looked at Guo Xiu's breakthrough twitching at the corner of his eyes, his face was almost green, the twelve pairs of chain locks on the twenty-fourth floor were opened almost instantly, and all the ascension processes had been completed in the blink of an eye!

"Really...... Perverted! ”

Yao Muchan exhaled a long breath, and suddenly found that his back was already soaked in cold sweat, and as Guo Xiu's climbing the stairs and unlocking the lock ended, only such a ridiculous thought appeared in his mind. Yao Muchan, as a powerful young leader in the blood drop, naturally didn't say anything about it, but compared to the guy in front of him, Yao Muchan suddenly felt as if he was just a normal person.

And since Guo Xiu's spine exercise was completed, his body seemed to be liberated, Huo Ran felt that he had arrived at a new world, infinite power surging in his body, and the coolness and comfort brought up almost immediately sobered up Guo Xiu's consciousness.

But no matter how awake you are, you are still in that dark space.

As his vision gradually cleared, looking at the curious gaze of Nuwa in front of him, Guo Xiu sat up and took a deep breath. The powerful internal organs kept stirring, as if they were all vibrating with Guo Xiu's inhalation.

With the nourishment of the next system, the strength of the internal organs increased at a speed that could be felt by the physical body, Guo Xiuxu clenched his fists, feeling his body from the inside out, as if it were cast as a whole, providing an endless stream of strength.

"Is that what it feels like?"
