"What's going on?" He Nuo asked.

Liao Xingyun took a deep breath and said, "Taste." As she spoke, she pointed to the foul-smelling puddle and continued, "The way out may be there!" ”

He Nuo was a little puzzled at first about the peculiar smell of this puddle, and then thought that he had taken Ying Lingyue's Youning Pill, and now he didn't feel anything about this smell.

Sure enough, Liao Xingyun said, "You still remember the rag I hooked off the corpse puppet, there was a smell on it at that time, and now I think about it, this smell is very similar to the smell of a puddle, so... This puddle must not be that simple. ”

As soon as Liao Xingyun said this, everyone secretly admired it, ordinary people cover their noses when they encounter a smell, so they can't avoid it, but Liao Xingyun can actually distinguish the difference in taste.

With Liao Xingyun's gaze, everyone slowly walked towards the puddle, and because they had expectations in their hearts, they all began to carefully look at the difference between the puddles.

He Nuo also looked at it, only to see that the puddle was surrounded by skeletons, and there were some rotten things floating on it, and the water in the puddle was very muddy, and there was no bottom in sight.

Ying Lingyue had already stepped forward, waved the long knife in her hand, and poked straight into the stinky puddle.

Liao Xingyun frowned slightly, thinking that Ying Lingyue was a little reckless, and before she figured out the specific situation, such a rash action might lead to an uncontrollable situation.

Unexpectedly, the long knife in Ying Lingyue's hand was half a human length, but the hilt of the sword was almost submerged in the water, but it was not yet finished.

Ying Lingyue pulled out her long knife and was surprised to find that after only a while, the blade had already corroded.

He Nuo's heart sank, and he secretly admired Ying Lingyue's thickness and fineness, if he didn't use the sword to test it just now, it would be very dangerous to let his skin touch the water.

Ying Lingyue raised the knife at this time to take a closer look, but found some differences in details, it turned out that the erosion marks on the blade showed a spiral pattern, and the erosion of the tip of the knife was serious, while the erosion of the handle position was slightly lighter.

Seeing this scene, Ying Lingyue pondered for a while and said, "The water in this puddle is flowing!" ”

But people with a little common sense know that the area of water flowing is not small, and if it is groundwater, it seems that a small puddle will definitely not be able to carry it.

"So..."Liao Xingyun also approached, pointing to the water hole, "There may be some kind of external force under the water, which causes the water in it to flow slowly." ”

Liao Xingyun hesitated for a while, glanced at He Nuo, and seemed to want to say something, but it was difficult to speak.

He Nuo has been with Liao Xingyun for a long time, he is too familiar with her, and he knows that she must have something to say, He Nuo made a gesture, meaning that if there is something inconvenient to say in front of everyone, you can go out, and the two will talk alone.

Unexpectedly, Liao Xingyun shook his head, gritted his teeth, and finally said, "I have a kind of condensation that can make the water surface clearer, but... Your blood may be needed, as this turbid liquid can be poisonous, and your Hidden Dragon's blood has a poison-suppressing effect and is the best medicine. ”

He Nuo originally thought it was such a big deal, but then he didn't expect it to be this matter, because after his hidden dragon blood was discovered, he had encountered such a situation many times, and he was used to it, and immediately lit up his arms.

Liao Xingyun was born in a medical family, and he would habitually bring some medicines with him, so he nodded a little, took out a small porcelain bottle from his arms, and stabbed He Nuo's arm with a thin knife, carefully picked up some He Nuo's blood, and then mixed in some white powder.

Surprisingly, after He Nuo's blood met the white powder, it changed rapidly, and in the end, it actually formed a transparent and clear liquid.

Liao Xingyun carefully poured all this transparent liquid into the puddle, and there was no trickle left.

As soon as the transparent liquid entered the water, the seemingly calm puddle swelled rapidly, showing a spiral-shaped rippling water wave.

In the end, the originally turbid liquid turned extremely clear, and all kinds of situations under the water were unobstructed.

Zhao Mingzhao clapped his hands and said, "It's also thanks to you as a beautiful medical immortal from the 'Liao family' that we have, otherwise it depends on a few of us, I'm afraid I won't be able to come up with a way to crack it if I want to break my head." ”

Ying Lingyue had been staring at the bottom of the water for a long time, her eyes didn't blink, and she suddenly said, "Look, is that a keyhole?" ”

As soon as Ying Lingyue's words came out, everyone didn't think about anything else, and stared at the bottom of the water carefully, and sure enough, in the middle of the bottom of the water, there was a concave slit, which seemed to be the keyhole.

Liao Xingyun thought for a while and said, "My kind of condensation can only make the water surface clear, but the corrosiveness in the water still can't be removed, so now, there is one last problem, which is how to send the key down through the water." ”

He Nuo saw that such a clear water surface seemed to be able to drink it directly, and some did not believe that the water was still corrosive, so he immediately pulled a strip of cloth and threw it into the puddle.

With a snort, the strip of cloth swirled in the water, and soon it was corroded into a puff of smoke, leaving no trace.

He Nuo was secretly speechless, thinking that the question Liao Xingyun said was definitely not a trivial problem.

Ying Lingyue thought for a moment and said, "I see that stone key, there are some blue spots on it, it seems to have been soaked in water, it may be able to resist the corrosiveness of this liquid, as long as we can find a way to send the key down, we..."

Before Ying Lingyue's words fell, Zhao Mingzhao interrupted him and said, "Shizi's words are a bit arbitrary, this stone key is something we have worked so hard to find, it has indeed been blistered, but who knows if it was soaked in this puddle?" Who's to say that it is resistant to this corrosion? ”

Ying Lingyue was still suspicious of Zhao Mingzhao's identity because she was affected by He Qingping's words just now, so she snorted lightly and didn't say anything more.

"I have a way!" Suddenly, He Qingping's voice came, and everyone looked back, only to see that He Qingping, who had just left, was slowly walking back.

He Nuo couldn't help but think, "Did He Qingping just eavesdrop on their conversation outside the door, or did he go out to do something and just came back?" ”

Liao Xingyun glanced at He Qingping, the expression on his face was very calm, and there were no emotional ups and downs because of He Qingping's words.

But He Nuo noticed that He Qingping was wearing a golden shell on his right arm at this time, and he saw that everyone was silent, and he actually reached out directly into the puddle!

This scene surprised Liao Xingyun, and he couldn't help but say, "This water is very corrosive!" ”

But He Qingping's arm was intact, only some bubbles came out of the surface of the golden shell, and He Qingping said, "This is our He family's golden dragon arm, it's quite strong, I can wear it and send the key to the keyhole below!" ”

Liao Xingyun saw that there was nothing to be done, this seemed to be the best way, so he had to silently hand over the stone key.

He Qingping wrapped the stone key with his hand wearing a golden shell, and then suddenly inserted it into the water, then spread out his palm, and sent the stone key forward forcefully, and the key was automatically inserted into the crack.

But the puddle was too deep, and He Qingping wanted to twist the key, but the water surface had not reached the top of his arm, and if he went down, it would corrode to his shoulder.

But as soon as the stone key entered the hole, it quickly let out a tremble, and then all the water in the puddle flowed, and the stone key was directly exposed to everyone's eyes.

"Can you finally go down?" He Nuo asked.
