"This light work, there is no one!"

Zuo Qingqiu saw that the dragon dust landed so accurately, and his body was as light as a small feather, and he didn't press the scales under his feet into the swamp at all, and he couldn't help but praise it.

However, Zuo Qingqiu couldn't help but say a word to Yu Wenze and Yi Tianlong, who were pulling the rope: "The rope must be pulled well, be careful not to fall into the swamp and be corroded and broken." ”

You must know that this rope tied to the dragon dust is the only way for the dragon dust to retreat, and it must be kept in the air.

Otherwise, if you accidentally get into the black mud and black water of the swamp, it will definitely be easily eroded.

In that case, if the front of the dragon dust is blocked and the scales behind are also corroded, it is very likely that it will not be able to get out.

"The second piece of material, what should I put in it?"

Dragon dust rummaged through Zuo Qingqiu's pile of materials, and finally took out a palm-sized piece of metal.

This metal is pitch black, and because it is relatively thin, it is not too heavy.

As a result, the power of dragon dust and martial arts surged, and he immediately used a soft force to carefully send the dark metal piece out, and finally placed it in the desired position.

"This is the Dark Devil Meteorite! The kid has good eyesight, but he's too ruthless!"

When Zuo Qingqiu saw it, he couldn't help but gasp and light up, slightly in pain.

Even in the canopy, the Black Devil Meteorite Gold is a rare refining material, and it has no price.

But in the hands of dragon dust, it is good to be reluctant at all.

"No!"

After the dragon dust put the black devil meteorite gold, he made a slight observation, and finally found that the black devil meteorite had a "snort" sound, and the white smoke was thick, and it was quickly corroded to the point that it was not visible.

"Waste!"

Zuo Qingqiu couldn't help but stare at it, as if a piece of meat on his body had been dug up, and then eaten by a dog and never came back.

"There's no way around it, isn't it?"

Longchen smiled, quickly ignoring the black demon meteorite, and continued to pick and choose among the piles of materials, and finally took out a dark golden claw that was extremely dry.

Although it was not known what kind of beast's claws it was, Long Chen could be sure that the air-dried claws were like a powerful metal cast, and they were extremely strong in the hand.

"This is the claw of the returning bird!"

Zuo Qingqiu gasped even more, and his flesh hurt more and more.

"Still useless. ”

The dragon dust drew the scoop in the same way, carefully sending the bird's claws to the desired location.

But as a result, although the dark gold claws were not corroded by the black mud swamp, because of their slightly heavier weight and small size, they actually sank directly into the thin mud in the black mud swamp at a speed visible to the naked eye, and quickly disappeared.

"I'm going to go! ”

Mo Xiaowan exclaimed.

The claws of the spirit bird, she had seen in ancient books, were extremely extraordinary.

If it is used as the tip of a sword, it is quite sharp.

Even if it is used by a martial artist of the Xuandan Realm, it can easily pierce the power shield of a powerhouse of the Flying Feather Realm.

"If I had known, I would have put it away and used it myself. ”

Long Chen saw that the materials of the returning spirit bird were like stones sinking into the sea, and he suddenly couldn't get them back, so he could only continue to grope in the pile of materials.

Anyway, these materials are all Zuo Qingqiu's, even if they are swallowed and corroded by the black mud swamp, they will not feel distressed.

"You take it easy! Try to use lighter, cheaper materials first. ”

Zuo Qingqiu couldn't help but blow his beard and glared and said: "This black mud swamp is extremely strange, it is not a good material, it will not be corroded, and even if it is not corroded, there is a weight problem to consider, if it is a little heavier, it will sink." ”

"Got it, don't interrupt. ”

Long Chen's eyes rolled, but he made Zuo Qingqiu speechless.

But then, Longchen really accepted Zuo Qingqiu's suggestion, and took out a bundle of silk threads like noodles, and it was very light.

"It's Purgatory Spider Silk! ”

Zuo Qingqiu breathed a sigh of relief.

In fact, he had taken out all the materials so arrogantly before, just because he couldn't wait to get through this black mud swamp.

But impulsiveness is the devil, and now Zuo Qingqiu regrets it a little.

He knew that he should have left the valuable materials and only took out the less valuable ones, so that no matter how much the dragon dust was squandered, he would not be in pain.

After all, it turns out that not just good materials will not be corroded by black mud swamps.

Moreover, even if the material is not corroded, there is also a weight to consider, sometimes the weight is too heavy, and even the best material will be sunk.

"Hey, this one works. ”

Longchen put the Purgatory Spider Silk away, and after waiting for a while, it was not corroded or sinking, so with a slight touch of his feet, the whole person flew away and landed lightly on the Purgatory Spider Silk.

"The second borrowing point has already been arranged. ”

Zuo Qingqiu's eyes froze: "Boy, work hard, there are still three points left." ”

"Do you want to be fast?

Longchen smiled.

The reason why he had to wait a while before throwing out an object was mainly spent on selecting materials.

On the one hand, he had to consider the degree of knowledge and characteristics of the material, and on the other hand, he had to consider the weight of the material, so it was inevitably slow.

If it's really fast, it's very simple, just take turns with the same materials, as long as it doesn't corrode and doesn't sink into the swamp, that's right.

"Let's take our time. ”

Zuo Qingqiu was speechless for a while, and hurriedly said after coming back to his senses.

Even the less valuable materials were hard to find, and he didn't want to be ruined by dragon dust all at once.

This is the materials he has worked hard to accumulate for many years, and he is still counting on the fact that after arranging the five borrowing points, he can collect some of the rest and go back.

"Your material, in fact, doesn't quite agree with the request, it's hard to guarantee that you won't take turns to fight. ”

The dragon dust picked and went, and finally threw out something that resembled a ceramic shard.

Although it weighs more than the Purgatory Spider Silk, this fragment is a concave arc, and it is believed that the recessed one facing upwards should not sink.

It's like a boat floating on water, if it flips over, it is very likely to sink, after all, it has no power to float.

"It's a broken vase fragment, and I'm going to use it to mend ......"

Zuo Qingqiu gasped.

Strictly speaking, this fragment is not actually a material, but a broken part of the finished treasure, which can be replaced as long as it is replaced.

However, he was still slow to speak, and it was too late to stop it, and the dragon dust had already been sent out.

As a result, Zuo Qingqiu soon stopped talking, and his eyes were almost spewing fire, which seemed extremely painful.

"The third point of borrowing is done. ”

Longchen smiled: "Old man, don't hurt your flesh, this treasure bottle fragment has played its due value." ”

"I really want to pump you. ”

Zuo Qingqiu gritted his teeth, but he was a little helpless.

After all, those materials that were taken out in one fell swoop were originally taken by him, and Longchen was not forced, right?

If he wants to blame, he can only blame himself for having a headache and brain fever for a while, and he was too impulsive to hand over all the materials to Longchen without picking.

As for the dragon dust, it's not that I don't feel distressed when I use it myself, of course, I use it when I feel good.
