It was surprisingly quiet in the dark cavern.

As if no one had ever been here, no one made any noise the whole time.

Zhang Yun lurked behind the stones, wrapped in a black cloak, fused with the darkness just like the Yin Earth Dragon he was confronting.

At this moment, he knew the existence of the demon beast, and clearly remembered its location.

On the other hand, the demon beast had no idea that there was an unexpected visitor in its lair, nor did it know that this uninvited guest had already targeted him.

One in the light, one in the dark.

This is the biggest advantage that Zhang Yun has.

And for a battle, these advantages are enough to determine the winner or loser!

"Ha ......"

When the yawn reappeared, I saw that the pink flesh ball suddenly twisted into a ball, and the blood and flesh pieces disintegrated, splashing back and forth in the limited space.

At the same time, Zhang Yun's soft cheers suddenly appeared!

"Soul Hook! Soul Eater! ”

Two rays of light, one red and one black, shot out, stabbing straight towards the black-brown ground!

As they were about to penetrate the ground, they seemed to encounter some resistance and were bounced out, one pierced into the walls of the cave and embedded deeply, while the Soul Hook flew into the depths of the cave and disappeared.

"What a tough skin, so that's why it's not recommended for Qi Refining Stage cultivators to hunt?"

Zhang Yun retracted his gaze with a solemn face, and beckoned to the direction where the spring water was, and a large number of clear springs bypassed the frost flowers and flew into the air to begin to shape.

"Qi condensation method, water control method!"

With Zhang Yun's control, they turned into spiked shapes and shot towards the Yin Earth Dragon, which was constantly struggling on the ground.

呲呲呲......

A large number of water spikes hit various positions of the demon beast, and the sound of dispersion was endless.

You don't have to look at it to know that these spells can't break through its defenses at all, and everything he does is useless.

But...... It doesn't really matter anymore.

The real killing move has already been used at the moment when the demon beast yawns.

He's just trying to be on the safe side and do as much damage as he can.

Inside the cave, the Netherearth Dragon howled in pain, and the piercing sound was accompanied by bright red blood foam, which was continuously released from its mouth.

I don't know what happened to it, but I forgot even the instinct to change color, and rolled around with a dark brown skin.

By this time, Zhang Yun had already tried all his offensive methods, and he already knew that his moves would not be able to pose a threat to it.

Looking at the desperately struggling monster, Zhang Yun's heart sank, and he simply didn't bother to do these useless things.

Taking advantage of the Yin Earth Dragon's howl, he dodged to the mouth of this thing, holding a piece of warm jade and aiming it at its throat.

Take advantage of your illness to kill you!

Now that he has chosen to do it, he won't give it any chance to turn over!

Even if it's a respite, he won't leave it behind!

"Yang Huo!"

The bright red jade suddenly released white flames and went straight into the body of the Yin Earth Dragon.

The violent flames were extremely unstable, and they rampaged through that bloody mouth, burning its flesh to shreds!

The roast lasted for about ten breaths before it slowly subsided.

And when Zhang Yun put away the "Yang Fire" again, the Yin Earth Dragon had completely turned into a whole piece of roasted game.

"So, I like sneak attacks, especially planned ones."

"If you can sneak up in the shadows and attack suddenly, who would want to fight head-on?"

Zhang Yun stretched out his hand forward, and the crystal clear "cicada wings" pierced out of the Yin Earth Dragon's mouth and fell steadily into his palm.

"The magic weapon worth three hundred spirit stones is worthy of your price, but it really rushed in without noticing, and after flying in, it was still under my control, and it began to break through from the inside, cutting off its vitality."

"These three hundred spirit stones are really not a loss, and I may have to rely on you more in the future."

From the very beginning, Zhang Yun had planned how he was going to fight this battle.

And the solution he came up with was to take advantage of the fast speed and high concealment of the cicada's wings to bypass the skin of the Yin Earth Dragon and start to cause damage from the inside.

His original plan was that if the idea came to fruition, he would fight this guy.

If it doesn't work, evacuate immediately, and wait for the next time to find an opportunity to start over.

But now it seems that the backup plan is no longer needed, the destructive power of the cicada wings is very strong, and the battle is solved in one go.

Its effect exceeded Zhang Yun's expectations, and he found that the fit between him and the cicada wings was simply terrifying, even through the skin of the demon beast, it could actually be manipulated in the air, which was a situation he had never expected.

In addition, looking back on the whole battle, he summed up a lot of gains in this battle.

Among them, the most important should be to recognize the importance of information.

If it weren't for the fact that he had chosen to lurk from the beginning, and if it hadn't been for the discovery of the Yin Earth Dragon's habit of exhaling for long periods of time, this battle would never have been so easy.

It was because of the sudden attack that the Yin Earth Dragon was unprepared and directly hit its vital point, so this battle that should have been very difficult became as simple as it is now.

"So, keep the good habit of lurking in the shadows, in battle, there is no more direct advantage."

As soon as he thought of this, Zhang Yun thought of the Qingxuan Falcon again, what he hated most was this kind of demon beast with a keener perception than him.

Thinking about his thoughts, he began to clean up the battlefield and dispose of the corpse of the Netherearth Dragon.

According to the list, it is very likely that the Yin Earth Dragon will have a Neidan after his death, and this guy's Neidan also has the effect of strengthening blood qi, and if he can find this thing, it will be very beneficial to him.

Because of the skin that insulates the breath, Zhang Yun has no way to directly use his spiritual sense to search for what he wants like ordinary monsters, and can only find it by reaching in with his hand.

Fortunately, he has a cleansing circle on his body, which is not a psychological pressure on him.

After rummaging through the body of the already ripe demon beast, a hard, cold touch suddenly came from his hand.

Feeling that familiar aura, Zhang Yun perked up and immediately took out this thing.

When he brought it to his eyes and observed it, he immediately determined that this was the Neidan he was looking for.

"Just like pearls, the small, white beads are as cold as ice to the touch, and they naturally emit a white mist."

"It's exactly the same as it is recorded in the directory, it must be that Nedan is correct."

"So, I'm really blessed?"

"With the Yin Earth Dragon's Inner Dan, and the Frost Flower, an innate spirit fruit."

"As soon as I came, I found two treasures, maybe this is the so-called chance, right?"

Zhang Yun stared happily for a moment, and without too much hesitation, he stuffed the Yin Earth Dragon's Inner Dan into his mouth.

I don't know if it's because he was roasted by the sun, but when he first put it in his mouth, he tasted the sweetness of the barbecue.

But immediately, this sweetness turned into coolness, as if the inner pill melted in his mouth, turning into a puddle of clear streams, sliding into his sea of qi along the eight veins of the Qi Sutra.

"It's ...... Improving my spirit? ”

Feeling the changes in his body, Zhang Yun hurriedly sat cross-legged on the ground and began to hold his breath and condense, running the Xuanming Yulin Technique.

As the exercises kept running, there were new changes in his sea of qi, and those clear streams like nectar flowed down the meridians in his body to the hundreds of bones of his limbs after purifying the true yuan in the sea of qi.

Wherever it flowed, the flesh and blood seemed to be nourished by the spring rain, and the meridians that had been silent began to become more tenacious and radiate new vitality under the nourishment of spiritual power.

Zhang Yun could clearly feel that his spirit body was becoming more pure and undergoing new changes.

"Is this the treasure that improves the flesh? No wonder Senior Brother said that so many people flock to it, and the changes it brings are too obvious! ”

I don't know how long it took for Zhang Yun to reopen his eyes and feel the changes in his body.

Now his body seems to have been tempered a lot, and he doesn't know how tough he is.

If it is said that the process of refining qi and refining qi is like gurgling water constantly forging his physical body and consolidating his meridians and qi sea.

Then the role played by Neidan is directly on his body, and it is directly strengthened in an external way.

Zhang Yun roughly converted, and he felt that the changes he had made after eating the Nei Dan were not much different from two years of cultivation.

Of course, this is just a physical change, and the aura is still the same aura, and it has not been qualitatively changed.

However, he had a feeling that his spiritual roots had become more refined.

It's similar to parchment, but it's a little stronger than that.

If I had to say a amount, it would be about a year's worth of parchment?

Zhang Yun didn't understand, that feeling was too vague, so he couldn't control the variables.
