The suction of this force was so huge that even with the strength of Li Qing and Chang Invincible, they couldn't resist it, and they were sucked in in an instant and disappeared between the bottom of the lake.

Not only the two of them, but everything at the bottom of the lake, such as mud, sand, gravel, plants, etc., and even the huge black Jiao on the ground that had been knocked out, rushed into a circular passage with this attraction.

If someone is on the surface of the lake at this time, they must be able to see that the entire Dragon Lake has formed a huge whirlpool, and the middle has almost become a hollow zone, and the lake water has been sucked into it.

Li Qing only felt that the whole person was spinning, he couldn't control himself, he could barely see that he was sucked into a circular passage, and rushed forward with the current, the speed was very fast, and there would inevitably be bumps and bumps in the middle, so he had to barely support a True Yuan shield to reduce the damage.

Since you can't resist, let it be.

The water flowed forward in the passage, and after an unknown amount of time, the suction finally became smaller, and finally slowly disappeared.

Li Qing was finally able to control himself, and immediately urged Zhenyuan to stop his body, and his feet stepped on the solid rocky ground, and he breathed a sigh of relief in his heart.

Chang Invincible was not far away, and he also stopped. The two of them looked at the place carefully for a moment, and where they were was a huge circular passageway, shockingly large, about a hundred zhang wide, almost like an underground cave.

The front of the passage is pitch black, deep and silent, full of mystery, and people can't help but feel a sense of fear when they see it.

"It's so dark in here. The invincible voice rang out, echoing through the passage.

"It would be nice if there was something to light it up. Li Qing muttered. Although the spiritual perception of the innate powerhouse is also very keen, it would be better if they could see things clearly. It's just a pity that this passage is filled with water and cannot be illuminated by an open flame.

"I have it!" Chang Wushu blurted out, and immediately took out a night pearl from the spatial ring, illuminating the darkness.

Li Qing couldn't help but be speechless: "You idiot, you didn't take out the night pearl earlier, why didn't you use it when you fought at the bottom of the lake just now?"

Chang Wushu blinked his big eyes, patted his head, seemed to suddenly realize, and said, "yes, why didn't I think of this." ”

Li Qing is angry, this guy is simply a second goods, a little too stupid, and he will be half angry when he talks to her.

The black Jiao was also sucked in, this entry was not far away, lying motionless on the ground, Li Qing felt that there was still a lot of life breath on its body, and said: "This big demon is not dead yet, let's solve it first, so as to prevent future troubles." ”

"Look at me!" Chang Wushu took out a sword from the space ring, then stepped forward, and cut off the head of the black Jiao with a sword slash.

It was neat and neat, and Li Qing was dumbfounded, this sword was at least a spiritual weapon, right? In addition to spiritual weapons, he couldn't figure out what other weapon could cut off such a hard dragon with one sword.

Why does this guy have so many treasures? Li Qing wanted to rob her a little. If she hadn't had such a hard backstage, I'm afraid there would have been people outside who would have wanted to do it, right?

"The dragon head belongs to me, and the dragon body belongs to you!" Chang Wushu finished speaking, and put the entire dragon head into the space ring, revealing a satisfied smile.

Li Qing shook his head helplessly, this guy is too shrewd, he put the benefits in his pocket. Don't look at the relatively large volume of the dragon's body, it seems that Li Qing has more benefits, but there is an inner pill among the dragon's head, which is the most important thing in the demon beast.

However, he didn't bother to bother with this guy, so he directly put the dragon body into the space ring.

"Let's go, go ahead and see where it is. Chang Wushu was full of interest, holding the night pearl and walking forward.

The Night Pearl illuminates the darkness, and the fear of the unknown lies ahead, and the two slowly advance along the passage, carefully guarded.

Such a passage obviously could not have been formed naturally, and they didn't know what it could be in the depths, and the two of them only felt as if there was a huge and invisible pressure.

After walking for a long time, they suddenly found that there was a layer of fiery red ore on the wall in front of them, and the two of them approached to take a look, and found that these ores were all red crystals, which looked crystal clear, flashing with a strange light, and were extremely beautiful in the dark.

"Could it be that these fiery red ores are red fire crystals?" Li Qing recognized this kind of thing and said uncertainly.

"It should be the Red Fire Crystal, an excellent material for refining!" Chang Wushu nodded.

"It's a nice bonus. ”

As soon as the words fell, I saw Chang Wushu rush to the red fire crystal ore with a "whoosh", and pried it up with her big sword.

"This is too monkey anxious, right?" Li Qing felt angry and funny, she had so many treasures on her body, how could she care about such a little red fire crystal?

He approached slowly, looked at it intently, and then his whole face changed, no longer a slow look, but became as invincible as ever, and hurriedly rushed to the fiery red ore, and pried it up vigorously.

"You guy, you have long found out that this thing is not a red fire crystal, how dare you lie to me like this! What the hell is this thing?" Li Qing yelled at her as he pried the ore.

"I don't know what you're talking about! Isn't this the Red Fire Crystal?" Chang Wuving's face did not change, pretending to be stupid.

"How can the Red Fire Crystal grow so blood-red, do you really think I'm stupid?" Li Qing snorted coldly, "Hurry up, you, what the hell is this thing? If you don't say it, be careful I'll rob you later!"

"I won't say it!" Chang Wushu was very tough.

"Forget it, don't care, anyway, let's dig it first. Li Qing used brute force to pry open one piece of fiery red ore after another.

The reason why he was so anxious to mine was because these ores were really extraordinary, they looked crystal clear, very beautiful, and as soon as he got closer, he felt a unique aura emanating from them, which must not be ordinary.

What is certain is that these ores are not red fire crystals, because red fire crystals are fire red, while these are blood red, although the colors are somewhat similar, but they can be quickly distinguished when you look closely.

I don't know how long it took to dig like this, but the two of them finally dug up the ore. Li Qing dug up more than sixty pieces, and Chang Wushu was about the same amount.

The two men were exhausted and panting, and sat down on the ground. Just now, in order to grab the ore, they used all the strength to eat milk. Li Qing's strength is great, but Chang Invincible's great sword is very sharp, and the results of the two of them are almost the same.

"Tell me, what are these ores?" Li Qing kept asking.

"I don't know!" Chang Wushu flicked his head, "In this way, how about I exchange a spirit stone for a piece of ore on your body?"

Li Qing pursed his lips: "Are you stupid for me? A piece of spirit stone? Do I lack such a little spirit stone? Even the Red Fire Crystal is far more than this price!"

"Then how about ten spirit stones for one ore?"

When Li Qing saw her like this, he felt more and more that this thing was extraordinary, and shook his head: "Don't waste your efforts, you won't change how many spirit stones you have!

Chang Wushu pouted: "Ten pieces!"

"Three! Three at most! If you don't tell me, then I'll go back and study it slowly, and I'll be able to find out." Li Qing said in a firm tone.

Chang Wushu saw that he couldn't deceive the ore in Li Qing's hand, so he could only say: "Okay, three pieces are three, this thing is dragon blood stone!"

"Dragon's Blood Stone!" Li Qing shook suddenly. He'd really heard of this thing, but he had never seen what the real thing looked like, so he didn't recognize it.

"Could this be a pure-blooded dragon's blood stone?" Li Qing took out a dragon's blood stone and observed it carefully, feeling the strange power in it.

Dragon's blood stone is a special material formed by the dragon's blood sprinkled on a certain stone and evolved over a long period of time. Dragon's blood stone is also divided into many types, such as what kind of dragon blood is coagulated, the blood of a real dragon or the blood of a dragon, the difference is very huge.

Just like the black Jiao that Li Qing killed just now, its blood can also form a dragon's blood stone, but this kind of dragon's blood stone is too low-grade and not precious.

And the blood-colored spar in front of him, the color is pure, transparent and clear, with a faint trace of terrifying power in it, it is obvious that this is a dragon's blood stone made of the blood of a pure-blooded dragon.

Dragon's blood stone is very widely used, usually it can be directly ground into powder, and then poured into water to dissolve, and the warrior sits in the water to practice and absorb the dragon's blood essence in the water.

In addition, there are more direct ones, which are simply ground into powder and soaked in water and drunk into the stomach, but in this case, the absorption and utilization efficiency is not so high.

In addition, dragon's blood stone can also be used as a refining material, which can refine precious weapons.

It can even be used as a medicinal herb. Many ancient recipes can only be refined with dragon blood as one of the dispensings, but the true dragons in the world are now extinct, so these wonderful ancient recipes are completely useless. But if you have Dragon's Blood Stone, it can be used as a substitute, and those ancient recipes that have been almost lost will be used again.

..........

"Don't look at it, this is a dragon's blood stone made from the blood of a real dragon. I've seen this kind of treasure before, so I can recognize it. Chang Wu's voice came from the side.

"True Dragon!" Li Qing was shocked, if it was a dragon blood stone turned into the blood of a true dragon, it would be too precious. No wonder this guy rushed forward in such a hurry to pry the ore, and it was really unprofitable not to get up early.

"Such a precious thing, you just wanted to exchange it for a spirit stone? How can this be reasonable, you cheated me!" Li Qing came back to his senses.

"It's a pity you weren't fooled!" Chang Invincible smiled cheaply.

"Why is there a dragon's blood stone here, and it's a real dragon's bloodstone?" could it be ......," Li Qing guessed.

"Here, it should be an ancient true dragon's lair!"

"I think so too. Li Qing nodded in agreement, and then said excitedly: "There must be a lot of treasures in the true dragon's lair, let's go, let's go in and find it now!"

"Hey, what about the three Dragon's Blood Stones you promised me?"

"Don't worry, I didn't say I wouldn't give it to you!" Li Qing sneered, he really hoped that the other party would forget, the dragon's blood stone was so precious, if he had to do it, he was not willing to hand it over.

After reluctantly handing over Chang Wuving's three dragon blood stones, Li Qing's face was full of unhappiness and he glared at her fiercely. I've been pitted by this guy!

Chang Wushu got these dragon's blood stones, and when he saw Li Qing deflated, he couldn't help but smile. Finally let this guy suffer, and a big breath of evil came out of his chest.

Since this is likely to be a true dragon's lair, there must be a lot of treasures inside, I didn't expect to be able to get such benefits after a trip, and the two of them walked towards the darkness ahead with excitement.

This passage is very long, and the two of them just keep walking and walking, and I don't know how long they have been walking.

Stop-and-go, and sat down to rest a few more times in between. Li Qing estimated that it would have been several days since he left, but he didn't expect that this true dragon lair would have such a long passage.

But when you think about it, it's a relief.

Because the size of the real dragon is generally very huge, just look at the diameter of this passage, you can know that it is about a hundred zhang wide, not to mention the length, I am afraid that its body is not less than ten miles long.

With such a long body, he could drill out hundreds of miles of passages with a casual drill into the ground, and Li Qing and Chang Wuving, two small human beings, were really too small in front of such giant beasts.

I don't know how long it took, but just when they were used to the unchanging dark passage in front of them, there was a sudden change in front of them.

They seem to have come to an intersection with a passage to the left and right, forming a cross shape.

"What's the situation? Could it be that there are two true dragons that have forged a nest here?" Li Qing was a little puzzled.

"It may also be that this real dragon likes to burrow into the ground, and drilled out several passages, forming intersecting points. "Often invincible speculation.

"No matter what, it doesn't matter if one or two, it's a true dragon's lair anyway, as long as you can get the treasure. ”

"And where are we going?"

"Keep going, one by one, and we have time to explore. ”

They continued to walk ahead, ignoring the other passage. Let's go to the end of one of the passages first.

I don't know how long I walked, but the unexpected happened again, and they came across a second intersection!

"It seems that there is more than one real dragon in this place, and it is a bit unbelievable that there are so many passages. Li Qing gasped.

"Hey, what do you think that's for?" said Chang Wushu as he pointed to a bush of plants on the edge of the intersection in front of him.

Li Qing looked carefully, and saw that this clump of plants looked like a clump of weeds, but the whole body was red, and it looked extremely beautiful.

"Oh, this must be a weed. Li Qing said as he walked towards the red grass, his speed getting faster and faster, and he was even a little anxious.

Chang Wushu was stunned for a moment, felt that something was wrong, and then saw Li Qing's movements, and said angrily: "You dare to lie to me!"

Because she saw that Li Qing rushed to the side of this pile of grass with a "sigh", and then began to pull these weeds in a hurry!

No matter how stupid she is, she knows that these red grasses are not ordinary, and eighty percent of them are also related to real dragons. Thinking of the Dragon's Blood Stone just now, she did the same, and suddenly came to her senses, and hurriedly rushed forward and began to pull out the weeds.

"Don't pull it out!" Li Qing snorted coldly, "These grasses must be made whole, and the roots must not be damaged! Otherwise, the grass juice will slowly overflow from the gap." ”

"Oh, that's right. Chang Wushu began to slowly dig down the soil around the red grass according to Li Qing's words, and carefully got the whole plant out.

After most of the day, they finally finished pulling out the red grass, and Li Qing got more than 30 plants.

"Tell me quickly, what are these plants?"

Li Qing snorted coldly: "Do you think I will tell you? What did you do to me about the dragon's blood stone just now?"

"Okay, I know it's wrong, just tell me. Chang Wushu began to be coquettish.

Li Qingcai didn't eat her set, and treated her body in the same way as others, and spit out two words coldly in his mouth: "Ten plants!"

"Ten plants! You think it's beautiful! How many do I have in total?" Chang Wushu jumped up suddenly, as if he wanted her life, and shouted: "Three plants at most!"

A smile appeared at the corner of Li Qing's mouth: "Okay, three plants are three." This grass is called dragon's blood grass, and it has a similar effect to dragon's blood stone. ”

He had read through the Medicine King Canon, and the level of medicine refining was so high, how could he not recognize this precious plant?

"It's that simple?" Chang Wushu was stunned for a moment, and then began to play scoundrel: "Such a simple sentence wants to take away my three dragon's blood grasses, no way!"

"Isn't the situation of the Dragon's Blood Stone the same just now?" Li Qing's face was not good.

"No!" Chang Wushu shook his head vigorously.

"My things are not so easy to pay! Since you don't give them, then I can only take them myself!" Li Qing finished speaking and grabbed it with one hand.

"I'll hammer you to death!" Chang Wushu picked up the giant hammer and smashed it down.

When!when!

The familiar rhythm sounded in the passage again, and the two of them started directly without saying a word, causing sparks to splash everywhere, and the entire passage rumbled.

After a battle, in the end, Chang Invincible retreated without suspense, and it took three dragon's blood grass to stop making peace.

"Give it to me earlier so you don't have to be beaten, I really don't know each other!" Li Qing sneered, and collected the three dragon's blood grasses into the space ring, very satisfied.

Chang Wushu glared at Li Qing fiercely, turned his head away, and felt very unhappy. The advantage that the dragon's blood stone took just now is now returned, and it was beaten severely, and it was a big loss.
