More than a month later, north of Qinglan City, there was a stretch of mountains about 10,000 miles away. Pen Fun Pavilion wWw. ｂiquge。 ｉｎfo

Frozen for thousands of miles, snowflakes flying.

Shi Mu stood in front of a dark cave entrance, wrapped in a thick coat, holding a crumpled cyan map in his hand, his eyes flickering slightly.

The map swayed in the cold wind, and six or seven circles were faintly visible on it, most of which had been crossed and only one was not.

There was a gust of wind in the cave in front of him, and he felt a cold chill constantly hitting his face, but in a few moments, his hair and eyebrows were stained with a thick layer of hoarfrost.

After standing for a long time, he put away the cyan map in his hand and strode towards the dark cave.

The robe on his body was a low-grade spirit weapon-level treasure robe purchased for nearly 100,000 spirit stones in Tongliufang, but it didn't actually have any actual defensive ability, but because of its special materials, it had a lot of effects against cold or ice attribute spells, and it was also suitable for this extreme environment.

When Shi Mu stepped into the cave, the snowflakes in the sky had filled in all the footprints left by him, and there was no trace of it.

The cave was pitch black and even colder, but fortunately it had a spiritual eye and was wearing a coat, so there was no need to worry.

The cave had only one passage, which stretched down and was not very spacious, and the walls were all hard rock, some of which were so sharp that he could barely pass, and in other places he had to bend down or turn sideways to get through.

All the way forward, after walking less than a mile distance, I came to a cave space more than ten zhang in size.

The whole space is vaguely oval, surrounded by ice, smooth as a mirror, except for the way to come, there is no other way out.

Shi Mu's eyes flashed with golden light, and he glanced around, his brows furrowed slightly.

According to his observations, the surrounding ice was more than 10 feet thick, and the front and bottom were all hard rocks.

Just when he was a little at a loss, his heart moved, as if he thought of something, he glanced up, and then looked down again.

"I see!"

He muttered to himself, luck in his fist, and slammed a blow to the ground below.

With an earth-shattering loud bang, the ice on the ground under his feet collapsed and collapsed, and his whole person fell weightlessly with the broken ice.

He was in mid-air, and with a single move, a cloud of white qi appeared at his feet, lifting him upward, and immediately stopped his fall.

He swept his eyes around quickly, and found that all around him were a thousand tough ice, like a mirror standing upright.

And he seems to be still a long way from the ground below.

He looked at the remaining hole above him from his fall, and with a push in his hand, the qi cloud dragged it downward.

After a few breaths, there was a soft "bang".

Shi Mu landed steadily, and then suddenly found that he was now in a huge underground cavern that looked like a crystal world, the ground in front of him was sloping down, and except for some ice stone pillars, it looked endless.

He stood there for a moment, then walked forward.

As a result, the more he walked, the more frightened he became.

Walking in this ice-carved and snow-paved environment, he felt as if he was in another world, and the road in front of him seemed to be incomplete, but the chill in the air became more and more intense, and he even began to feel a trace of cold and biting chill through his coat and into his body.

Even if he urged his true qi to protect his body, he still shivered from time to time.

Shi Mu gritted his teeth and continued to walk forward.

After walking for half an hour, except that the terrain is getting lower and lower, and the temperature is getting lower and lower, everything around is still the same, without the slightest change.

That robe and body protection true qi were almost useless at the moment.

Seeing this, Shi Mu couldn't help but smile bitterly.

He was a mid-level martial artist, and at this moment, he actually felt like he was going to be frozen!

In desperation, he had no choice but to urge his mana, and two wings of fire suddenly stretched out from his back, and then wrapped his body before continuing to stride forward.

After walking like this for another quarter of an hour, his steps stopped again.

Because in front of him, a wall of ice appeared, blocking his way.

Shi Mu looked at the ice wall in front of him, and his face changed for a while.

According to the information of the shopkeeper of the Heavenly Treasure Pavilion and the map he gave, the Qi of the Extreme Yin can only be found in the most cold places, and it generally appears in the depths of the earth, and there are only seven possible locations in this extremely cold mountain range, and he has explored all the first six, but he has found nothing.

Now he is in this last place is not only the coldest, but now he has penetrated more than ten miles into the ground, and the deepest of the first few places is only two or three miles, so it can be seen that this should be the most likely place where extreme yin qi appears, but there is still no trace of it.

Shi Mu sighed lightly and looked at the ice wall in front of him.

The ice wall is crystal clear throughout, a hundred zhang high, extending infinitely to the left and right, I don't know how long.

"Knock Knock"

Shi Mu stepped forward, knocked heavily on the ice wall a few times, and then put his palm on it, only to feel a chill to the bone.

The temperature here is already unbelievably low, and thanks to the Red Ape Fire Sutra that he practiced, and with the power of the Yang to protect his body from the first turn of the Nine Turns of Xuangong, if he was an ordinary earth-level martial artist, even if he had this robe to keep out the cold, he would have already been frozen into a humanoid ice crystal.

Even so, every time he stayed in this place for a few more moments, the true qi in his body would be rapidly depleted to maintain the protective fire wings against the cold.

After Shi Mu groaned for a while, he released his divine consciousness and searched for it on this ice wall, and at the same time urged his spiritual eyes to enter the ice wall through the layers of ice crystals, wanting to find some clues.

However, as far as his line of sight could see, there was still a vast piece of ice, and there was no shadow of the Extreme Yin Qi in sight.

Shi Mu had no choice but to choose a direction, along the ice wall, and continued to explore as he walked.

If he doesn't turn over this place, he is not willing to give up.

As a result, he walked for about half an hour, and another very open cave appeared in front of him, and the ice wall extended directly into it, becoming a cave on one side.

When he stepped into the cave, he felt depressed.

In this cave, there is also nothing, and the temperature has dropped a lot.

Although it is indeed possible that there is extreme yin qi in such an extremely cold environment, the harsh environment here is far beyond his imagination, and if he continues to look for it like this, the true qi and physical strength in his body are constantly consumed, and it is definitely not a long-term solution.

Just when Shi Mu was about to sit down in place and rest for a while, his heart suddenly moved, as if he had discovered something.

He immediately closed his eyes, and when he opened them again, he hurriedly walked forward.

As a result, in the deepest part of the ice wall, I found a slight bulge, which looked a little special.

Seeing this, Shi Mu took a deep breath, but his eyes showed a strong joy.

He had just accidentally noticed that it seemed that the cold currents around him were coming towards this cave under some kind of attraction, and finally converged towards this slight bulge.

Shi Mu immediately activated his spiritual powers, and the golden light of his eyes lit up again, and he shone towards the inside of the ice wall at this slightly raised place.

The ice wall in front of me is more than ten zhang long, which is obviously much thicker than the ice walls on both sides.

And when he looked inside, Shi Mu saw that in the center of the ice wall, there were more than ten strands of airflow that were as thin as gossamers and almost transparent, like spiritual snakes.

After seeing this gossamer, a strange intuition suddenly rose in his heart, and it became stronger and stronger.

This feeling was very similar to what he had felt when he saw the Ice Phoenix's true blood before, as if it was a strong desire from the depths of the Origin, but the feeling at this time was much weaker than the previous time.

"Extreme Yin Qi!"

Shi Mu's heart suddenly rejoiced, he was almost sure that those filaments hidden in the ice wall were the Extreme Yin Qi he was looking for.

However, when he calmed down and came back to his senses, he was a little speechless.

The ice wall here is not only extremely cold, but also thick, and it seems that it will take a lot of effort to break it open and take out the extreme yin qi in it.

Shi Mu thought for a while, and as soon as he opened his mouth, a small black stick the size of a toothpick flew out of it, and in a flash of black light, it suddenly turned into a long black stick with eyebrows, holding it in his hand.

It's the iron rod of Ruyi!

Ever since the Falling Star Dark Iron was smelted into the Ruyi Stick, it had become like the Meteorite Mo Knife, and could no longer be included in the storage ring.

Fortunately, it was as big as he liked, so Shi Mu shrunk it and put it in his mouth.

Shi Mu held the Ruyi stick with both hands, and then the stick stepped forward and took two steps back, widening the distance from the ice wall.

After gathering momentum, Shi Mu took a step forward, grasped the stick with both hands, and swung it forward vigorously.

"Bang!"

Just hearing a loud noise on the surface of the ice, countless white ice crystal powders scattered and exploded.

And the wishful iron rod was violently oscillated, but it was hit and flew back.

Shi Mu staggered back a few steps with the Ruyi stick in his hand, stabilized his figure, glanced at the place of impact, and immediately frowned.

I saw that on top of the huge ice wall, a circular cavity appeared, which was covered with spiderweb-like cracks.

Those cracks seem to be dense, but they are actually only distributed on the surface of the ice wall, and do not penetrate deep into the ice wall.

Obviously, the powerful blow just now did not cause any substantial damage to this thick ice wall.

Shi Mu glanced at the center of the cave a few times, but the long black stick in his hand suddenly shortened, and turned into a small black stick again, which he retracted into his mouth.

Hula!

The two red flame wings that were originally wrapped around Shi Mu's body suddenly opened, and then a white flame of light swirled up from his left arm, and at the same time, the red color lines of the Dao Dao also appeared on his arm.

Without the wings of fire around him, Shi Mu didn't feel cold at all at this time, on the contrary, there seemed to be a stream of heat surging around his body, making his whole body warm and very comfortable.

As the white flame above Shi Mu's left arm lit up, the surrounding temperature also rose a lot.

At this moment, Shi Mu's eyes looked through the ice wall and found that the few wisps of cold qi hidden in the wall also seemed to be stimulated by the power of the Yang in his left hand, and became more active, constantly impacting the ice wall, wanting to rush towards Shi Mu's side.
