With the operation of the exercises, the demonic energy circulates endlessly in Hao Yu's internal organs and meridians, bringing strength to Hao Yu at the same time, it also brings him great pain, perhaps because of the particularity of demonic energy, it is not suitable for human use, although these demonic energy concentrated in Hao Yu's dantian has been processed, but its violent characteristics still exist, Hao Yu's current situation is really painful and happy.

"This kind of pain is simply torment, a pain from the mind, but ~ I must persevere, I must become stronger!"

Beads of sweat kept sliding down his eyelids, but Hao Yu didn't frown, but his flushed face knew that he was not doing well now. If someone was in front of Hao Yu at this time, they would definitely be surprised by the scene they saw in front of them, only to see that outside Hao Yu's body, wisps of red breath came out, and it had already formed a layer of aura about an inch thick outside Hao Yu's body, and there was a tendency to become more and more intense, more and more red, and turn into a blood-red color, of course! Hao Yu didn't know that this situation appeared in himself, and he was now immersed in refining his body bones.

Gradually, a powerful breath burst out from Hao Yu's body, this breath, different from the breath of inner energy, but there is an overwhelming strength, this power is Hao Yu's physical strength, if someone is near him at this time, he will definitely be shocked by this stronger and stronger breath that erupts from his body.

"It worked!"

After nearly twenty days of retreat, Hao Yu's physical strength finally broke through, and at the moment when his physical strength broke through, the layer of aura that lingered around him was already a blood-red color, thick and solid, like an entity, giving people a feeling of agility and liveliness, as if this layer of blood-red qi had life.

The moment Hao Yu's physical strength broke through, that layer of blood-red qi, like Wanchuan returning to the sea, quickly drilled into his body, with the help of this breath, Hao Yu's physical strength was stabilized, when the blood-red light in Hao Yu's eyes flashed away, the powerful sense of oppression on Hao Yu's body also disappeared, making Hao Yu look like an ordinary person at this time.

"Hmm, is this about to break through?"

Hao Yu was still immersed in the joy of the breakthrough, which made him unexpectedly surprised, within a few minutes after the breakthrough of his physical strength, it came again, and before he had time to taste the powerful feeling after the improvement of his physical strength, Hao Yu suddenly felt that the breath of the internal organs was surging, and the situation when the skill was about to break through, it was so similar, the boy who was just about to get up hurriedly sat cross-legged again, ready to meet the improvement of the realm of strength.

The expected realm breakthrough did not come as Hao Yu expected, but a pain like tearing of the internal organs, which made Hao Yu almost faint in pain.

"What's going on? Okay...... Painful ......"

Holding his chest tightly with his hands, Hao Yu felt as if his heart was about to explode, but his internal breath was still uncontrolled, pouring into his major organs, gradually! Hao Yu felt that his internal breath seemed to be out of control, he wanted to control them, but he couldn't, and the pain was entangled with him, and there was a tendency to wreak havoc.

"Quick! Try to guide the internal breath into the body bones, your current situation is a necessary process for the physical body to be refined and improved, and the internal organs and internal breath energy are fused with each other, if you can't successfully fuse, you only have two results, either the physical body collapses, or the internal organs collapse, both of which are fatal. ”

The reminder of the Crystal Soul Tower was like a guiding light, and Hao Yu, who listened to its reminder, immediately did what it said, and it didn't take long to stabilize his physical condition and free himself from the heart-rending pain.

"Sister Huitong! According to what you said, there was a terrifying devil on this mountain before, can't it break this big rock? If it could have been done, it should have escaped from here a long time ago, and this is the exit. After listening to Guo Huitong's story, Xiaohu blinked his eyes and suddenly looked at her curiously and asked.

After she was free, Guo Huitong listened to herself from Hao Yu, and Fu Yuting told her three companions some things they didn't know, of course! When she talked about these things, she added some necessary materials, such as things she had not experienced before, Guo Huitong added herself to it, and let herself be a little limelight in it, and the girl did this, naturally wanting to satisfy her little pride. But now, she was asked this question by Xiaohu, and she didn't know how to answer it for a while.

Seeing her best friend stuck, Fu Yuting, who was sitting on the side, looked at Guo Huitong and smiled slightly, and then helped her out: "There are so many strange and inexplicable phenomena here, and that powerful monster can't escape, it's not strange at all, maybe because it only exists as a soul, so it can't break through some kind of hidden barrier on the top of the big mountain in front of me, and has been trapped on the top of the mountain." ”

"That's right! Someone helped to break the siege, Guo Huitong naturally hurriedly took the opportunity to get rid of his embarrassment.

"You guys had a great chat, can I join in?"

Hao Yu suddenly walked over, and seeing that everyone was chatting happily, he joked.

Seeing Hao Yu coming over, Guo Huitong, who was still a little embarrassed in his heart, jumped up like a happy bird, and ran to the boy's side: "How is it?

"Of course, if you succeed, you can't be disappointed, ah~ You dug so deep again?"

When Hao Yu walked to the dark boulder, he looked down into the deep pit, and he was also surprised to see that the pit was much deeper.

There was a crisp click, and under the gaze of his companions, Hao Yu smashed the stone under his feet with one punch, and opened a large piece of stone that was broken, Hao Yu reached out and picked it up, and showed it to Guo Huitong and them.

"Brother Hao Yu is so strong! Just now, he didn't seem to use his internal breath, just the strength of his body shattered this incomparably hard stone, it was really powerful. Looking at the dark stone in Hao Yu's hand, Xiaohu's eyes were bright, and he was happier than he had successfully broken the stone.

Next! Hao Yu was angry, his fists came out, and he smashed the dark stones under his feet one after another, letting it break and disintegrate little by little, and finally knocked off the stones that were more than a meter thick, and also officially touched the energy node that he had already sensed, but it was difficult to get out of the primary, the hope of going out from this secret realm was right in front of him, Hao Yu and his companions almost couldn't suppress the joy in their hearts, one by one, laughed out loud.
