Although Yi Xuan had been cultivating, his soul perception had been released to prevent any special changes from happening.

All this that happened around him naturally couldn't escape Yi Xuan's perception.

Yi Xuan knew that after losing so much fire crystal, many places in the fire crystal mine had begun to be unable to support it and were about to collapse. As long as this pyrometallite collapses, it will inevitably cause a volcanic eruption.

There is not much time left for Yi Xuan.

"You must support it for a while, it's almost ready!"

Now Yi Xuan has no other way, everything has reached the last moment, it is impossible to give up all his efforts, he can only hope that this fire crystal mine can support for a while longer.

As time passed, the shaking became more and more violent, and began to spread throughout the Pyrolite.

"Hold on!"

Yi Xuan shouted in his heart. The purple light on the Zixiao Sword has reached five feet and eight inches, and he also feels that bottleneck, as long as he is given a little more time, just a little time, the Zixiao Sword will advance smoothly, and his physical body can also be improved at the same time.

Rumble!

A stone the size of a human head fell, less than a meter away from Yi Xuan. Yi Xuan didn't care, and he didn't even tremble in his heart.

Thundered!

This stone is like a fuse, and in an instant, one by one, the stones fall with it. These stones are only the size of a fist, but the big ones are the size of a grinding disc, and when they are smashed, they are no less than a giant hammer weighing hundreds of pounds. If it is hit, an elephant will probably die instantly.

Yi Xuan was located in the center of this cave, and the dozens of stones that fell at the beginning did not hit Yi Xuan. But as more and more stones fell, Yi Xuan couldn't help but be hit by the stones a few times.

Most of these stones were only the size of a fist, and even if Yi Xuan was hit, it was not a big deal. With this level of injury, even Yi Xuan's skin couldn't be broken. But there were a few stones that were the size of a human head, and although Yi Xuan was not injured after being hit by these stones, he also felt a burst of pain.

"Hold on!

Yi Xuan's willpower was so strong, this bit of pain couldn't make him feel it at all. Even if the pain was ten times greater, Yi Xuan would never frown.

The most important thing for Yi Xuan now is to buy time, this stone falling is not to bring him trouble, but to tell him that time is running out, the fire crystal mine is about to collapse, and the volcano will also erupt.

Thundered!

The stones kept falling, and one of the stones the size of a grinding disc was just above Yi Xuan, and it was smashed on the top of Yi Xuan's head.

Rumble!

After the stone hit Yi Xuan, he rolled to the side. Yi Xuan was unharmed, and even his expression never changed.

"It's coming, it's going to be done!"

Although Yi Xuan's face was expressionless, he was still a little anxious in his heart.

Suddenly, Yi Xuan's heart was overjoyed.

"I feel it, it's a bottleneck! As long as I rush over, my physical body can be equivalent to a human-level superlative weapon!"

Without too many words, Yi Xuan's mind was concentrated, and he continued to use his Xuan Power to repair the damage caused by the red light. This is a job that takes time, and the red light's attack is so strong that it is impossible to change with Yi Xuan's thoughts.

Fortunately, in the six days inside the gold concentrate, Yi Xuan's mind has been sublimated, and he has already learned how to calm his heart slowly. At that moment just now, Yi Xuan's heart was still anxious, but now, when it was becoming more and more dangerous, Yi Xuan's heart calmed down.

"There's still time, as long as I break through physically, it's still too late. ”

The sword qi on the Zixiao Sword had already reached five feet and nine inches, and it was only one inch away from six feet.

Boom Boom!

The earth seemed to tremble, and as the pyrolite collapsed, the magma had begun to tumble. The magma soared to a height of tens of meters in an instant, and the temperature on the volcano rose at a terrifying rate.

Boom Boom!

The fire crystal mine continued to collapse, most of the passages were almost impassable, and the cave where Yi Xuan was located had almost been blocked by the falling stones.

Yi Xuan's eyes were closed, and he sat cross-legged on the ground, but there were large and small stones all around him, and his whole body had been buried by the stones.

However, Yi Xuan didn't care, and he didn't even move his mind.

"It's coming, it's almost ready!"

At this time, Yi Xuan's impact bottleneck had reached the most critical moment, and the Zixiao Sword was only the last point away from advancing to the end.

Boom Boom!

The fire crystal mine collapsed even more severely, and from the outside of the mountain, you can see that the side of this volcano is collapsing and tilting little by little. The power caused by the collapse and tilt of this volcano is almost like turning over a mountain and a sea, and it can be heard within a radius of hundreds of miles.

The magma under the volcano is tumbling even harder, and the hot magma is almost about to rise hundreds of meters into the air and jump out of the crater. In the meantime, a small amount of magma has begun to erode from the cave to the igneous crystal. Once this magma enters the cave where Yi Xuan is, Yi Xuan is probably in a catastrophe.

Rumble!

At this critical moment, Yi Xuan finally broke through the bottleneck of his physical body, and his physical strength reached the level of a human-level superlative weapon.

Yi Xuan opened his eyes, and a fine light shot out of his eyes.

Yi Xuan stood up, and the stone pressing on him was instantly bounced away. A powerful aura burst out from Yi Xuan's body, this aura was almost comparable to the original silver-armored beast! It was conceivable that after the physical body breakthrough, Yi Xuan's strength must have been greatly improved.

As soon as his mind moved, this powerful aura was put away. Looking at the stones scattered around, a trace of satisfaction flashed in Yi Xuan's eyes, the weight of these stones added up to more than a thousand catties, and before he could do it, he had to use nearly thirty percent of his Xuan power to bounce these stones away.

But just now, Yi Xuan did this just by relying on his own strength, it can be seen that after the physical body reached the level of the human level of the ultimate mystic, Yi Xuan's simple strength was no worse than that of an ordinary ninefold peak mystic.

Yi Xuan turned his eyes to the Zixiao Sword and saw that the Zixiao Sword was only one step away from advancement, and after Yi Xuan broke through, it also broke through.

Rumble!

The purple light on the Zixiao Sword skyrocketed violently, reaching a length of six feet, indicating that the Zixiao Sword had officially advanced to a high-grade artifact.

After the Zixiao Sword advanced, the red light egg that originally surrounded the Zixiao Sword was still five meters in size, and the purple light on the Zixiao Sword flashed, and the red light egg was also instantly absorbed. After absorbing this red light egg, the purple light on the Zixiao Sword deepened slightly, but it did not continue to grow.

Seeing this, Yi Xuan smiled slightly bitterly in his heart.

"The red light contained in this remaining red light egg accounts for at least one-tenth of the entire fire crystal mine, which can make Zixiao's sword light grow by two or three inches just now, but now it can only make its color slightly darker. From this point of view, if I want Zixiao to advance again, I must at least find a fifty-mile-long human-level top-grade ore vein, or find a twenty-mile-long human-level top-grade ore vein. ”

It's hard to find either of these!" Yi Xuan sighed. However, he didn't sigh for long, magma didn't wait for anyone, as soon as he picked up the Zixiao Sword, it was directly a storm and nine turns.

Boom Boom!

An extra passage immediately appeared in front of Yi Xuan, eight steps to chase the wind unfolded, and with one dodge, Yi Xuan came out of this cave.

At the same time, the magma has finally begun to erupt in full force. A ** magma instantly soared to a height of thousands of meters, and then fell rapidly. At the same time, streams of magma began to erode down the cavern towards all the voids within the volcano.

Soul perception is in full swing, searching for a way out. The magma eruption was too loud, and it was difficult for Yi Xuan to know it.

Yi Xuan searched for a long time and found that the road he had chosen was almost completely blocked.

"There's no way, now I can only carve out a path by myself!" Yi Xuan waved his hand, and a six-foot-long purple sword qi burst out, splitting a boulder that was blocking Yi Xuan's front. Yi Xuan dodged and continued to move forward.

At the same time, the magma has eroded away from all the mines.

Zizizizi!

Countless stone walls slowly melted under the magma and turned into a puff of green smoke.

Boom Boom!

The eruption became more intense, and more magma spread into the mine.

In a short time, all the mines were filled with magma, all the stones that fell were almost melted, and countless passages were reopened.

At this time, Yi Xuan still hadn't come out yet.

After dozens of breaths, it seemed that the volcano was about to stop, and with a bang, a figure suddenly erupted from a certain mine.

This figure was in tatters, holding a purple long sword, it was Yi Xuan.

Yi Xuan, who came out of the mine, knew that he was not out of danger. Eight steps to chase the wind unfolded, and in a few breaths, Yi Xuan came to the top of the volcano.

Yi Xuan finally breathed a sigh of relief at this time, and turned his head to look at the volcano that was still erupting.

The rolling heat wave continued to hit Yi Xuan, and the sound of the volcanic eruption was deafening, almost resounding through the heavens and the earth.

"The eruption is so loud that it can be heard for hundreds of miles, and it will surely attract others. My consumption in the volcano was too great, and the Xuan power in the dantian was less than thirty percent left. If I attract other people who want my life, I'm afraid that there will be a lot of bad luck, and I must leave as soon as possible!"

Thinking of this, Yi Xuan immediately launched eight steps to chase the wind, found a random direction and rushed away.

Yi Xuan, who left, didn't notice that as soon as he came out, a man in a black robe stared at him.

"Yi Xuan, I actually met him here, I really had nowhere to find my iron shoes, and it didn't take any effort to get there. I couldn't find him for so long, but I didn't expect to see him here. Okay, today is your Yi Xuan's death!"

The black-robed man's eyes flashed with a fierce light, and he chased after him in the direction Yi Xuan left. His speed was not much slower than Yi Xuan, who was chasing the wind in eight steps!
