"Roar!" Seeing this hateful human woman who had injured herself in front of him, the Star Rock Beast roared angrily, and a violent momentum erupted all over its body, and then a burst of earthy yellow light burst out from its arm, and it slammed into Mu Xuehan with a punch.

There was a majestic energy wave above the fist, which directly shook the space and made a piercing whistling sound.

Seeing the fierce fist print, Mu Xuehan naturally wouldn't go to the other party, and then the jade hand was raised, and the sword blade was quickly retracted, followed by a little tiptoe, his body jumped slightly, and flew backwards, instantly out of the attack range of the Star Rock Beast.

"Whew!" Suddenly, the star-rock beast's ferocious punch directly slammed into the air, directly smashing the air in front of it into a violent spatial ripple, and the earthy yellow light on the fist also dissipated.

At this time, the Star Rock Beast had no intention of continuing to pursue Mu Xuehan, and hurriedly withdrew its fist and pounced in the direction of the deep cave.

"It's not that easy. However, at this moment, Mu Xuehan sneered, and a tempting arc was drawn on the corner of his mouth, and then his light body jumped again, blocking the front of the Star Rock Beast.

"Wind Shadow Sword!Drink!" Immediately, Mu Xuehan let out a clear drink, and the cyan long sword suddenly burst out with a burst of cyan light, and then shook it heavily.

As a roar of energy sounded, a cyan sword shadow three or four meters in size suddenly slammed into the huge body of the Star Rock Beast with a fierce momentum.

Feeling the extraordinariness of the cyan sword shadow, the Xingyan Beast's expression changed, a trace of horror appeared in its eyes, and it hurriedly stopped its advancing body, and hurriedly burst back to avoid the attack of the cyan sword shadow.

At the same time, I saw that the cheeks of the Star Rock Beast were bulging wide, and there was a faint earthy yellow light on its face, and a violent energy was fluctuating in its mouth, presumably this guy was brewing a powerful attack.

Just when Mu Xuehan and the Star Rock Beast were in a fight, Ling Yunfeng had already driven a flying sword down to a distance of less than twenty meters from the bottom of the deep cave.

As it continued to fall, Ling Yunfeng also felt that there seemed to be something extraordinary about this deep cave.

He could clearly feel a faint strange energy fluctuation in this deep cavern, although this energy was extremely weak, but it still could not escape the prying eyes of his keen soul.

Moreover, Ling Yunfeng also found that as he descended deeper into the depths of the cave, this strange energy became more and more intense, and the fluctuations became more intense.

The distance of more than twenty meters was not far, and Ling Yunfeng controlled the flying sword almost instantaneously, and soon landed at the bottom of the deep cave.

Standing in the deep cave, Ling Yunfeng felt that the strange energy had also reached an extremely rich level, with gusts of light energy winds sweeping through the cave.

And the strange thing is that this strange energy seems to be somewhat similar to the energy contained in the star core that he hunted. Although it is very different when you feel it carefully, there is an inexplicable connection between them.

"Hey, what's going on?" At this moment, Ling Yunfeng suddenly let out a startled sigh, and his eyes suddenly lit up.

He felt that when these strange energies approached him, the martial qi in his body actually began to slowly swim according to the operation route of the Heavenly Refining Technique, and he seemed to have a very excited feeling, as if he was about to swallow this energy from the outside world.

"Could it be that the Heaven Refining Technique can devour these energies?" Ling Yunfeng frowned, his expression was a little surprised, he felt that his Heaven Refining Technique seemed to be able to devour these energies.

"No matter, try it!" Ling Yunfeng said lightly, and then the martial energy in his body turned rapidly, with a faint hint of excitement and anticipation, he secretly carried out the Heavenly Refining Technique.

With the operation of the Heavenly Refining Technique, the strange energy in the entire cave seemed to be pulled by an invisible force, rapidly surrounding Ling Yunfeng's body, lingering around his body, and then pouring into his body along the open pores on the surface of his whole body.

Then I saw that as soon as those strange energies entered Ling Yunfeng's body, the martial qi in his body surged, instantly wrapping these energies and immediately following the operation route of the Heavenly Refining Technique, the muscles and veins in the body quickly swam.

It had been running for a week before those strange energies turned into a trace of pure martial energy and flowed into the sea of qi in Ling Yunfeng's body.

"Can it really be devoured?" Feeling the few thin martial qi energies that had increased in the sea of qi, Ling Yunfeng said with a happy expression on his face.

I didn't expect that these weird energies could really be refined, although the martial energy just now was not a lot, but it was comparable to the martial energy absorbed by oneself in a quarter of an hour of cultivation on weekdays.

If you cultivate in this deep cave, as long as you have these strange energies coming in a steady stream, then your cultivation speed should be more than ten times faster than usual.

"Boom!"

Just as Ling Yunfeng was excited in his heart, a violent sonic boom came from the sky. Immediately broke his idea of cultivating here.

If you want to cultivate here, you have to deal with the Star Rock Beast above, but seeing that this situation is almost impossible to achieve now, let's wait until there is a chance to talk about it later.

But it doesn't matter, anyway, the energy in this cave doesn't seem to be very much, and it is estimated that it will not last long to swallow itself.

Immediately, Ling Yunfeng smiled helplessly, forcibly suppressed the excitement and extreme desire in his heart, and stopped running the Heavenly Refining Technique with some distress.

As the Heavenly Refining Technique stopped working, the strange energy that lingered in the sky around him also dissipated suddenly.

"Alas!" Sighing slightly, Ling Yunfeng shook his head and began to look for the kind of black jade that Mu Xuehan said in the deep cave.

Glancing at the bottom of the deep cave, I saw that the bottom of the cave and the surrounding walls were full of gray-brown earth and stones, where was there any jade?

However, this cave is not big, just after looking at it for a while, Ling Yunfeng immediately discovered a trace of something special in this cave.

I saw that in this deep cave, those strange energies and spiritual energy were gently fluctuating, and I immediately looked at a corner of the cave that slowly gathered and gathered there.

Seeing this, Ling Yunfeng's eyes lit up, and the corners of his mouth outlined a strange arc, revealing a faint smile, generally where aura or energy gathers, there will be treasures, so there should be something special about this inconspicuous corner.

Immediately, Ling Yunfeng smiled slightly and walked towards the corner.

Standing on the corner, I looked at it at a glance, and saw that this corner was nothing special compared to the rest of the cave, it was still a gray-brown earth and stone floor and wall, if it weren't for the energy and aura of the surrounding sky converging here, Ling Yunfeng would really not have found here.

Immediately afterwards, Ling Yunfeng glanced at the ground a few times, as if he had found something, and his gaze was slightly condensed.

Immediately, Ling Yunfeng squatted down, took out an ordinary long sword, and gently dug up the ground here.

After a while, he dug a hole more than two feet deep in the ground, but he saw that there was still some gray-brown dirt in the ground, and nothing unusual was found.

However, a trace of excitement appeared on Ling Yunfeng's face, and he held the long sword in both hands to speed up and dig up.

Because Ling Yunfeng found that as he dug up the dirt on the ground, the surrounding energy and aura suddenly became more violently fluctuating, constantly converging here, so he guessed that there was definitely some extraordinary treasure underground.

He continued digging for a while until a pit was dug nearly a meter deep.

At this time, Ling Yunfeng habitually used the palm of his hand to scoop up the soil in the pit. It was just as soon as his palm reached into the dirt that he suddenly felt a warm touch, and he touched something hard and somewhat warm.

Seeing this, Ling Yunfeng suddenly felt happy in his heart, a smile appeared on his face, and he quickly swept away the layer of soil covering this thing with his palm.

After half a sound, a small black crystal jade suddenly appeared in the soil pit, and I saw that the surface of the jade was extremely smooth, and there was a warm feeling when the palm touched the jade.

As soon as this black jade stone appeared on the ground, the surrounding energy and aura suddenly fluctuated violently, converging towards this piece of jade, and bursts of slight energy strong winds swept up in the cave, forming a small energy vortex in the sky above the black jade after a while.

As the aura and energy in the space at the bottom of the cave continued to converge into this energy vortex, the energy vortex also became larger and larger, and the power to pull energy and aura became more powerful.

"...... this?" Ling Yunfeng looked at this scene in surprise, his eyes widened, he didn't expect that this seemingly ordinary jade stone was so terrifying, and it actually had the effect of gathering energy and aura.

Looking at this situation, this piece of jade is afraid that it can gather the surrounding energy and aura to more than several times the original, so doesn't that mean that if you cultivate on this jade, the speed of cultivation can definitely be several times faster than before.

Thinking of this, Ling Yunfeng's heart under his chest suddenly beat faster, his expression became extremely excited, and his face turned red from being too excited.

Immediately, Ling Yunfeng's eyes trembled, flashing with blazing light, and he looked at the black jade in the pit in a daze and muttered, "This thing is not just a little good for cultivation as Mu Xuehan said, right? It is definitely a rare genius treasure, and it is also a treasure of incalculable value." ”

"Ling Tian, have you found anything? At this moment, Mu Xuehan's hurried voice came from the top of the cave.

Listening to this voice, it can be seen that the other party's current aura is a little unstable, and the voice is mixed with wheezing, obviously with her strength, it is not so easy to entangle that second-order late-stage Star Rock Beast.
