When Hao Yu pressed the stone with his hand and crossed the internal breath energy for almost two hours, Hao Yu was already exhausted, and he couldn't stand steadily, so he could only half-lean against the stone wall. What's even more serious is that his internal breath is also about to run out, and with a bitter face, Hao Yu's face is dark, and he muttered: "Before the internal breath is exhausted, I don't know if this mechanism can be opened, this time! ”

Looking at the stones that were still unchanged, Hao Yu had a feeling of wanting to cry without tears, after all, he gritted his teeth and persevered until now, and he couldn't blame anyone.

Seeing that the time had come to the second hour, Hao Yu felt that there was not much internal breath left in his internal organs, and the stones under his palms were still indifferent, Hao Yu couldn't help but feel that he had done useless work: "It's over......! There is still no movement, even if you are powerful, swallow so much of my internal energy. ”

When the last trace of internal breath was exhausted, Hao Yu was exhausted, next to the stone wall, slid on the ground, and gasped for a few breaths, he hurriedly crossed his legs and prepared to meditate and breathe to recover his internal breath.

Click~Click!

A crisp sound echoed in the stone room, followed by several loud sounds, Hao Yu, who was originally about to meditate and vomit, was shocked, although he was weak, he still supported the ground with both hands, let himself get up from the ground, swaying.

"Haha~ Finally, the mechanism is finally opened. ”

Seeing a large stone protruding from the stone wall, Hao Yu shouted happily, his voice a little hoarse.

"Very good! You've found the mechanism to open the treasure ground, now! You've got a quarter of an hour to open this stone door, and if you don't push open the stone door in a quarter of an hour, then you'll have nothing to do with those creations!"

The voice in his head sounded again, and what he could bring to Hao Yu was not good news, on the contrary! After hearing this, he felt like a bolt from the blue.

"A quarter of an hour? In my current state, a quarter of an hour to push open this stone door? How is it possible? This stone door looks at at least several tons, and I am now exhausted in my internal breath, and I have little strength left, how can I push it open?"

Despite saying this, Hao Yu still didn't want to miss the so-called creation in his heart, so he gritted his teeth! The young man took out a few special energy crystals from the space ring, held them in the palm of his left hand, and began to use them to replenish his own internal breath, on the other hand, Hao Yu swallowed a handful of nutritional supplements, like in this way, quickly recovered his strength.

A wave of heat rose in his abdomen, Hao Yu seemed to feel another force, filling his body, and then!

As expected, he didn't move at all, although Hao Yu felt that he had exhausted his strength, and the stone door in front of him, which was more than two feet thick, just didn't move at all.

"Come again!"

The palm of his left hand was bright, his right hand was bent, and Hao Yu leaned on the stone door and pushed the stone door with one right hand.

Time passed little by little, several energy crystals in the palm of the young man's left hand, one after another turned into points of light, and were absorbed by Hao Yu, and when the energy crystals were used to restore the internal breath to the third minute, the young man finally felt that his internal organs had a not weak internal breath, and he no longer felt hot in his stomach, and his strength seemed to have recovered some, and the feeling of fatigue was slowly disappearing.

Feeling his rapid development, Hao Yu was in a good mood: "It seems that if you don't push yourself, you really don't know where your limit is." ”

Hah~

Seeing that there was still a quarter of an hour and the last two or three minutes, Hao Yu still couldn't push the stone gate, but the light in the young man's eyes did become brighter and brighter: "Very good......! I should be able to push it away. ”

Retracted the right hand that was pushing the stone door, and the left hand that had been behind his back was put in front of him, and when he opened it, there were fragmented energy crystals flowing from Hao Yu's fingers to the ground, he didn't care, but smiled, and turned around!

Click!

Hao Yu finally pushed the heavy stone door, gritting his teeth! Leaning forward, the young man's feet struggled to the ground, which was infused with a thick internal breath, and his hands were also surging with internal breath, so that Hao Yu made a force, clicked a few times, and the stone door protruding from the stone wall was pushed by him and slid aside, revealing the door blocked by the stone door.

"Little one, perseverance is commendable, now! go in and find your own creation, you will not be disappointed. ”

The old voice sounded in Hao Yu's mind again, this time! He happily listened to the words of this ancient remnant soul, and without hesitation, he stepped into the doorway.

Laugh at!

As soon as he walked into the doorway, he heard a small sound from inside, and then! Hao Yu felt that his eyes lit up, and the front was illuminated by the firelight, and he saw another stone room, a stone room that was several times larger than the stone room outside.

"Hmm, I feel like there's something here, echoing my breath, could it be that there is something related to the Nine Extremes Exercises?"

As soon as he stepped into the stone room, Hao Yu's heart was shocked, because he sensed that there was a faint breath in this stone room, echoing the breath on his body, as if calling him, and he felt excited because of his arrival.

Following the breath that seemed to be nothing, Hao Yu found the thing on a row of wooden shelves placed in this stone room, which was a black stone with strange lines, at first when he saw it, Hao Yu even thought that he was looking for the wrong one, but when he took the black stone in his hand, Hao Yu's eyes lit up all of a sudden.

"This is the Nine Extremes? This stone, how does it make me feel like I have seen the rubbing secret book of the Nine Extremes? It doesn't seem to be the same, this feeling, as if what is hidden in this stone is the real secret book of the Nine Extremes, is it possible? The Nine Extremes Exercises I practiced before were realized by my predecessors from this stone?"

Hao Yu couldn't help but feel like this, because as long as he held this stone in his hand, the feeling of touching the veins of his internal organs would involuntarily emerge.

Holding the black stone, Hao Yu looked at the shelf in front of him again, and he was quickly shocked by everything in front of him, because on this row of three-layer shelves, they were all like the ones in his hand, looking at ordinary stones.

"Could it be that the ancient martial arts passed down by the ancients were inspired from these magic stones?"

Looking at a bronze plaque standing above the shelf, Hao Yu read out a few words engraved on it, although he was sure that he didn't know those quaint words, but he didn't know why, when he saw those words, it was as if he recognized them in an instant, and read them out casually.

Shocked, Hao Yu took a small step back, looked at the bronze sign, and felt like a ghost: "What's going on? How could I recognize such an ancient text? Could it be because of those ancient remnants in my mind? It's the remnants of my predecessors, which affect me?"

"Young man, it's not that we affect you, but the words on the brand, it is depicted with energy far beyond the king-level energy level, the wonderful use of ancient martial arts, not to mention this, now you know too little, and you don't understand too much, but as long as you read this, you can know the rough. ”

The old man's voice sounded in Hao Yu's mind, and when he finished speaking, a thick parchment book, for some reason, suddenly flew in front of Hao Yu, the young man thought for a while, and reached out to take the parchment.
