Grunt.

A wisp of bubbles appeared in Chen Mu's mouth and nose, the martial artists of the Five Visceral Realm can interact with the outer heaven and earth by virtue of the internal breath cycle, and they can also breathe from the water, but this place is located deep underground, and the pressure is also quite large, if Chen Mu only initially breaks through the Five Visceral Realm, there will be a little burden to swallow the internal breath here, but now after two tempering, there is no pressure.

He walked a few feet along the leftmost rock wall, then looked at a place on the rock wall, suddenly pulled out the knife from the sheath, and stabbed at the rock wall, this time containing the power of Yuan Gang's true strength, but it only pierced three inches.

Chen Mu's expression did not change, he continued to swing the Flowing Fire Knife, slashed a few times in succession, dug out a piece of blue-silver ore from the rock wall, put it in his hand and weighed it slightly, and felt a chill in his tentacles.

"Is it a cold jade mine?"

He shook his head and threw the piece of cold jade away.

Relying on the artistic conception of Genshan, he can perceive the flow of the leylines in the rock wall, so it is easy to perceive some areas located in relatively shallow places, where the leylines do not circulate smoothly, and it is obvious that they are not a complete whole with the rock wall.

However, based on this perception alone, he can't be sure what is inside the rock wall, and the cold jade that was excavated is also of medium quality, and it is worth dozens of taels of silver when it is made into a jade pendant outside, but for the current Chen Mu, it is naturally an abandoned thing, and it is not worth pocketing.

Chen Mu closed his eyes and continued to perceive the rock wall, then continued to walk forward along the rock wall, and after walking for a while, he put his hand on a raised rock formation, carefully perceiving the inside, and vaguely felt that there was a wisp of heat coming.

"Is it the Xuanhuo Mine?"

Chen Mu's eyes flashed slightly, and he immediately swung his knife to chisel, but after slashing twice, revealing a pale red structure inside, he stopped chopping, shook his head and continued to walk forward.

It's not a Xuanhuo mine, it's a piece of Yanyu mine, although the quality is also high-grade, but he has a whole bed for this thing, and the fist-sized piece inside is naturally far from looking.

The further you go, the more you go inside.

The more Chen Mu was amazed in his heart, the more he was amazed at the great achievements of heaven and earth nature in this world.

Because when he walked out of this cave and entered the next one, which was more open and more than ten zhang in circumference, it was obvious that the rock wall here was not the same rock as the rock wall of the cave he had just had.

In other words, although this underground structure is a whole, it is a variety of rock formations, which have been forced together by the power of the leylines for an unknown number of years, and formed into a single one.

"If a person can have this kind of great power, he can almost move mountains and reclaim the sea, it is indeed no different from the legendary gods and Buddhas."

Chen Mu continued to go deeper.

Soon came to a place near the center of the stone cave, where the stone wall under his feet was rugged, and after he carefully perceived it, he waved the flowing fire knife in his hand and chiseled the stone wall at the bottom of his feet, and soon his eyes moved slightly.

Then he swung his knife again and dug out one of the pitch-black stones, about the size of a fist.

It's a very heavy start!

It was only the size of a fist, but it was as heavy as a giant grinding disc.

"Heavy stones."

The light in Chen Mu's eyes flickered slightly.

This is completely different from the previous two Cold Jade Ore and Yan Jade Mine, it is one of the truly rare rare ores, its weight far exceeds all ordinary ores, and it is one of the core materials for forging heavy treasures!

For example, if someone is good at hammering, after arriving at the five visceral realms, the strength is thousands, so naturally the heavier the hammer, the greater the power, but if the hammer is too big, even if it can be wielded, it is very inconvenient.

The heavy stone is the core material of this kind of treasure, only a fist-sized piece, it is extremely heavy, if the whole is built from it, then it does not need to be very large, it can have extremely heavy power.

"If I practice the artistic conception of Genshan to the second step, I can actually control the power of the 'heavy knife', but the Flowing Fire Knife is already a top-quality phase knife, and adding a heavy stone will destroy its quality ......"

"Or, how about another sword?"

Chen Mu suddenly had such an idea in his heart, and felt that it might be okay.

A knife is light, a knife is heavy, and it is also a secret way to match the heavens and the earth, and it is also suitable for him to play, but this is just an idea for the time being, relying on this heavy stone alone to forge a treasure heavy knife, although it can also work, but the quality will not be very high in the treasure, and it also needs to be supplemented with some other materials.

But no matter what, this is a good harvest, Chen Mu thought about it and took it into his pocket, but it was too heavy and shook his head, and finally took out a golden silk from his belt, tied it, and hung it on his belt.

It would be nice to have special storage.

Chen Mu had some thoughts in his heart for a while, but quickly shook his head to dispel it.

A long time ago, he thought that there was no such thing, but later when he talked to Meng Danyun about the 'spiritual weapon', he learned from Meng Danyun that among the most precious spiritual artifacts in the world, there is a piece called the 'Qiankun Pot', which has no killing effect, but has the ability of 'storage' he mentioned.

This spiritual weapon was once in the hands of the Great Xuan Imperial Court, as the treasure of the four armies of the Blue Dragon and White Tiger, which made the four armies rampant in the world without scruples, but then it seemed to be lost in a battle, and its whereabouts are unknown.

Of course, Chen Mu had this kind of supreme treasure in mind, but he also knew very well that with his current level, even if he really obtained this kind of top spiritual weapon supreme treasure in the world, it might not be a good thing.

Even.

Don't say it's him, even if it's a big sect like Qixuanzong that sits in a state, if he has such a thing, it will also attract coveting from all directions, and the trouble is constant, after all, with this thing, he can solve the biggest problem of military food transportation, and there is a chance to reproduce the power of the four armies of the Blue Dragon and White Tiger that swept the world in the Great Xuan Imperial Court, who doesn't covet three points in today's world?

"I don't know how this kind of spiritual weapon involving spatial characteristics is forged, but since its name is called Qiankun Pot, it may also have a certain relationship with the artistic conception of Qiankun."

Chen Mu thought to himself.

But soon he put these unrealistic thoughts behind him and continued to go deeper along the cavern.

……

Grunt.

A small amount of bubbles appeared between Meng Danyun's mouth and nose.

With a sword in her hand, she was walking along a somewhat narrow passage, and soon she passed through the passage and came to a very open cave, and then she looked at several inverted stalactites in the center of the cave.

These stalactites are silvery-white, hanging on the top wall of the stone cave like icicles, and at the tip of the bottom, there are a few pearls that are fluorescent, the color is like white jade, and the shape is round.

"Strange Spirit Beads."

"Sure enough, my perception was correct."

Meng Danyun's eyes showed a hint of joy.

Qi Ling Bead, rumored to be in the depths of the earth's leyline, after the power of the leyline extraction, thousands of years to be born of the spiritual object, its interior contains a rich heaven and earth Yuan Qi, and the temperament is very gentle, for the warrior to enter the realm of the six intestines, condense the six organs have an excellent effect, can greatly enhance the accumulation of the six intestines vitality.

Although she didn't plan to enter the Six Organs Realm too early, she would have to cultivate in the Five Organs Realm for another year or two, but being able to obtain this kind of spiritual object was naturally very useful, and after entering the Six Organs Realm in the future, she would be able to save at least one or two years of work.

Swish.

Meng Danyun stepped out in one step, and the whole person swam to the center of the stone cave at once, stretched out his hand and grabbed it, and took a large, two, and three strange spirit beads into his hand, and put them into the personal sachet for storage.

But at this moment, her eyes suddenly changed slightly, as if she noticed something, and the whole person suddenly wandered away in the water, and quickly retreated towards the passage from which she came, and was about to retreat into the passage in an instant.

But at this moment.

Laugh at!

The water split all of a sudden, and a little blood light lit up in the pitch-black passage, and a light blue Emei thorn emerged from the darkness and stabbed Meng Danyun head-on, blocking Meng Danyun's retreat.

"Blood Hidden Building!"

Meng Danyun's face was slightly gloomy, and the silver water sword in his hand was horizontal, and the flowing water within a radius of several zhang suddenly shook, bursting out with a surging power, and a black-robed figure shook out of the dark passage, and at the same time, the silver water sword in his hand also collided with the Emei thorn that glowed with cold light.

The black-robed figure snorted, as if it couldn't withstand the power of Meng Danyun's blow in the water, and the whole person was repelled at once and fell into the darkness of the passage.

But.

After this stop, Meng Danyun also lost the opportunity to retreat along the passage from which he came.

Just as she made a decision, she was about to enter the passage again, and when she broke through the assassin of the Blood Hidden Tower head-on, the water in the stone cave suddenly surged and turbulent, and two ring-shaped mandarin ducks broke through the water with a roar of Yuan Gang's true strength.

If Meng Danyun rushed into the passage again at this time, he would not only face the assassin of the Blood Hidden Building in the darkness in front of him, but also face the sharp blow from behind, so he had to look slightly gloomy at the moment, give up the idea of retreating along the original road, wave the silver water sword in his hand, roll up a water curtain, and forcibly block the flying mandarin duck Yue, and then the whole person swam up.

Above the cave.

There's also a cave passage that leads nowhere.

In an instant, he repelled the assassin of the Blood Hidden Building, blocked the attacking mandarin duck, and chose to escape from another passage, Meng Danyun's choice was correct, seeing that the whole person was like a swimming fish in the water, and when he was about to sink into the passage above the stone cave in an instant, a jade-colored bamboo stick snatched it horizontally and knocked it head-on.

This blow was not only accompanied by the surging Yuan Gang's true strength, but also a slight warmth rippled, making the water temperature in the stone cave seem to warm up all of a sudden, enveloping a beam of warm water and falling head-on.

Meng Danyun's gaze became colder.

The silver water sword in his hand swung upward, and the flowing water in the entire stone cave was surging and vibrating, and it suddenly broke the 'spring water' that fell head-on, and then the sword blade collided with the jade-colored bamboo stick, and it was also swept away at once.
