Fu Yun looked at it, this thing was so thick and long, soft like a worm, but he couldn't tell which end was the head and which was the tail.

Burst!

This thing seems to be able to sense automatically, as soon as Fu Yun gets closer, it blows out a lot of sand and dust, and the cave is immediately full of rapidly flying sand grains, and there is nowhere to hide.

Fu Yun felt a fierce murderous aura coming, and he didn't dare to make reservations, when even if he came out of the three layers of sword qi of the Qingcheng Sword Technique, he went straight to that strange insect.

The strong sword wind directly blew away the sand and dust, and the sharp sword qi was like three sharp knives cutting through, directly cutting the insects to pieces.

Fu Yun clapped his hands and looked at the broken insect corpses all over the ground with disdain.

It's scary to look at, but it's actually nothing, and I think it's so powerful for such a big guy.

However, something was about to happen to the proud one too soon, and just as he was triumphantly about to move on, a sudden change occurred.

The fragments of the corpses of the insects all over the ground suddenly began to gather together, and they were about to reunite into a new one.

Fu Yun couldn't help but be stunned.

What's the matter? This thing can't be killed!

The power of the three-layer sword qi of the Qingcheng Sword Technique, Fu Yun still has some understanding.

Even the monks of the Gathering Spiritual Period did not dare to resist with their bodies.

Is this worm immortal?

I can't care so much, let's run for my life first.

Fu Yun hurriedly turned around and ran into the main hall, as long as he ran to the mysterious small room, he would be able to save his life.

Everything will wait until you go in and make plans, this bug is so weird.

Fortunately, he practiced the Divine Transformation Method during his retreat, otherwise he would not have been able to outrun the worm at this time.

Despite its bloated size, it doesn't run slowly at all.

And this guy can even be deformed, and his body is very soft.

The stone wall leading to the main hall only opened a door the size of one person, and Fu Yun was relatively thin and passed smoothly all of a sudden, but this fat insect flattened his body and actually passed through it quickly.

Oops!

Fu Yun looked back at the situation, was startled, and ran faster.

When I got to the stone wall, I quickly smashed the big lighting beads over. After a flash of bright light, the stone wall slowly began to become transparent.

Brother Shibi, can you hurry up?

Fu Yun was really anxious at this moment, but the speed of change of the stone wall was still so unhurried, and he had to disappear completely before he could pass through.

Behind him, the strange bugs chased closer and closer.

Fu Yun knocked on the stone wall eagerly, tried it but still didn't work, why did he feel so slow today, this is to want his life.

"Break it for me!"

Seeing that the insects were chasing in front of him, Fu Yun raised his hand and slashed over with three sword qi, and then slashed the strange insects.

Looking at the fragments of insect corpses slowly gathering on the ground, this is not a way to kill or not. Fortunately, there was enough time for this time, because the stone wall was about to disappear.

Hiding in a small room, Fu Yun's heart suddenly became much more steady.

I turned my head to look at the cake-faced futon on the jade bed, and I don't know why I always felt that it seemed to move.

What's going on, this guy can't be laughing at me, right?

Look at the strange bug again, it lost its target at the moment, and suddenly began to ramble around like crazy.

The medicine residue on the floor of the Dan pharmacy, as well as the dust, were rubbed on its body, and then I saw that the size of this insect had become a little larger.

Could this be the legendary Dune Bug?

Seeing that insects could absorb dust and grow into large bodies, Fu Yun suddenly thought of this terrible name.

This dune worm is not very powerful, but it is very difficult, and after the body is broken, it can be recombined to fight again.

Of course, this rebirth is not unlimited, and each time it is reborn after being attacked, it will become smaller and need to absorb sand and dust to recover its body.

If the body is continuously shattered, the Dune Worm will become smaller and smaller. When it finally becomes the size of an ordinary person's finger, it can be regarded as a prototype.

If you are killed again at this time, you will not be able to resurrect yourself.

However, Fu Yun was embarrassed to deal with this heavy dune worm, because he was not good at explosive attacks.

And if you use sword energy, the consumption of your own aura is particularly large, and you will not be able to bear it if you attack too many times. Then use a layer of sword qi to attack it?

No need!

If this was outside, maybe Fu Yun would consider using the attack method of low-level sword qi to wear down the dune worm again and again, and finally beat it back to its original form and kill it, but now this is in a mysterious small room, and if you don't reward it with a newly developed purple fire talisman to taste, you can't even be worthy of the name of your seal master.

With a flick of Fu Yun's wrist, two small purple flowers floated out, looking elegant and weird.

The dune worms outside seemed to sense the threat of the purple fire flower and wanted to turn around and escape.

However, that kind of opportunity obviously didn't exist, and the purple fire flower fluttered extremely fast, reaching the top of the dune worm in the blink of an eye. Burst!

It doesn't sound very powerful, like a ball leaking air.

Of course, this leaked not gas, but a purple flame with terrifying heat and extremely high viscosity.

The body of the Dune Worm is very large, the first half of it is in the Dan Pharmacy, and the second half is still in the hall and has not entered.

It didn't stop the purple fire from igniting it, and spreading from beginning to end was a matter of a few breaths.

This dune insect is really a bit capable, and even the purple fire that can instantly scorch the stone on its body did not kill it immediately.

"Whew!"

The giant insect howled in pain, and its body writhed violently, trying to extinguish the flames on its body.

However, it was all in vain, and the purple flame seemed to grow on it, and it could not be shaken off. The dune worm can only get smaller and smaller in the struggle and rolling, and gradually disappear into this world.

All that was left was a thin layer of dust on the ground.

Fu Yun saw the appearance of the dune worm struggling in pain, and completely realized how ferocious this purple fire talisman was

。 Such a difficult insect, even the sword trick cut it twice without dying, and it was burned to the ground.

If it weren't for the thin layer of gray marks on the ground, I wouldn't even suspect that it had ever come.

Fu Yun remembered that this dune worm should live in the western region, and he actually came here.

It seems that the scale of this demon beast attack is not small, and I have to mention this matter to Steward Wang.

Without the hindrance of the dune worms, Fu Yun once again walked through the main hall to the cave.

I thought the cave would get dirty, but I didn't expect it to become cleaner.

That bug looks so disgusting, and it's not bad to clean.

In fact, this is because the characteristic of the dune insect is that it can absorb dust on the body and make it a part of the body. It walked into the cave, and it was as if it had been carefully brushed with water, and the walls of the cave became smooth and clean.

Although the insect was dead, Fu Yun still didn't dare to be careless, and walked out cautiously, for fear that something strange would rush in at the entrance of the cave.
