On the surface of the Poison Dragon Sea, the poisonous mist is full of miasma, and the poison under this sea is not much inferior to the sea surface, even the surrounding sea water is purple-black, and accompanied by a pungent smell......

And the moment the two jumped into the water, the purple-black sea water around them was like a hungry beast seeing its prey, and it actually rushed towards the two of them, but then, the blue sea dragon ball in Mu Yun's arms emitted a dazzling light, and then, the halo spread out, and finally formed a light shield around the two, blocking the crazy poisonous sea water from the outside......

And the stream of sea water also seemed to be afraid of the light mask, and it was quickly dodged and opened, just like that, wherever Mu Yun and the others swam, the surrounding sea water was scattered as if fleeing for their lives, until they left, it slowly flowed back, as if human beings had their own consciousness......

"What did you just see? Or did you hear something? Murong Wan'er asked softly.

Mu Yun shook his head slightly, but his body was not slow, and he continued to swim towards the sea, but his mouth was deep, "I can't hear what that voice is talking about, but it seems to be calling me, since you can't make it, I think this thing should have something to do with me, right?" ”

"Double-headed Jiao is right, you'd better not touch anything, this is the Diyuan Continent, not the Renyuan Continent, you still, it's better not to come nonsense" Murong Wan'er said softly.

But Mu Yun turned his head and looked at Murong Wan'er with a smile, and quipped, "What? Do I come around a lot? ”

"What do you say?" Murong Wan'er's beautiful eyes glanced at Mu Yun and said lightly.

Mu Yun shook his head and smiled, but he didn't care anymore, and after a while, he sighed softly, "This poisonous dragon sea is really worthy of its name, I can't imagine that the poisonous dragon clan has such a ability, it can completely turn a sea area into a sea of poison, and I don't know how many people's lives the sea dragon clan sacrificed at that time to calm this sea."

Mu Yun's voice fell, and he heard Murong Wan'er next to him say lightly, "I don't think that's the case, even if the poisonous dragon clan's ability reaches the sky, it is just a group of poisonous snakes after all, how can this sea of ten thousand miles be poisoned like this, and have you noticed that as we gradually go deeper, the color of this sea water is slowly changing."

After Murong Wan'er mentioned it, Mu Yun noticed that the surrounding sea water, unconsciously, had become completely black as ink, and looking down again, it was already pitch black, fortunately, it was protected by the blue sea dragon balls, otherwise, with this toxicity alone, it was really not enough to send many lives......

Then Mu Yun seemed to suddenly think of something, and suddenly looked at Murong Wan'er in surprise, "You mean, this poison ......?"

Murong Wan'er tapped her head lightly, and her eyes looked straight at the dark depths of the seabed, "Most of the things that exude poison are down here, and it is very likely to be related to the sound you heard."

As soon as Murong Wan'er's words fell, the two of them saw a faint pale green light flickering in the dark depths of the seabed, flashing by, as if they were signaling, or guiding......

Now that he has come here, there is no reason to retreat, no matter what he is, let's take a look first, and Mu Yun actually has another idea in his heart, that is, the origin of the five elements, as early as the time of Tianxing Island, Mu Yun has already noticed the thick wood true qi in the air, what does this mean, it means that the wood of origin is on this Earth Yuan Continent, and it is very likely to be nearby, since it is nearby, then there is only the vast sea in front of him, so Mu Yun insisted on coming here, hoping to have an unexpected harvest......

As they spoke, Mu Yun and Murong Wan'er had already gone some distance deeper, and gradually, even if the two of them were protected by the Blue Sea Dragon Ball and had True Qi to protect their bodies, the strong pressure of this extremely deep sea still made the two of them feel a little difficult, and the most obvious thing was that they were a little slow to move......

And at this moment, in front of the seemingly not far ahead, the pale green light flashed again, but the distance seemed to be no different from before, Mu Yun and the others were advancing, and the pale green light, it seemed, was also moving forward, but it was guiding the two from time to time......

In this way, the two of them kept swimming towards the bottom of the sea, and the pale green light also emitted from time to time, so repeatedly, I don't know how long it took, even when Mu Yun felt a little tired, the light of the blue sea dragon ball finally illuminated the ground in front of them, and the two of them had swam to the bottom of the sea unconsciously......

The soles of the two stepped on the ground, Mu Yun frowned slightly, and wondered, "It's strange, they all went to the bottom of the sea, why did the green light seem to disappear instead"

And just when Mu Yun was puzzled by this, he suddenly heard Murong Wan'er say lightly, "There"

Mu Yun followed Murong Wan'er's gaze, and sure enough, not far in front of him, the pale green light flashed again, as if he was teasing the two of them......

Mu Yun was also angry in his heart, and secretly scolded, "Damn, the master wants to see today, who are the demons and monsters, dare to make fun of the master"

As soon as he thought of this, Mu Yun was holding back the fire in his heart, and his body also had the strength to kick the ground, and his body suddenly rose, chasing straight towards the light, Murong Wan'er wanted to stop it, but Mu Yun had already chased it out, and in desperation, he had to follow......

And this time, I don't know if Mu Yun's speed was too fast, or because the pale green light didn't want to hide at all, Mu Yun actually came to him in just a moment, regardless of thirty-seven twenty-one, he reached out to grab the light, held it in his hand, and between the tentacles, he only felt a warm palm, and then, the palm of his hand was spread out, but there was nothing, that thing seemed to disappear out of thin air......

At this time, Murong Wan'er also came and asked softly, "What is it?" ”

"I don't know, if I catch it, it's gone" Mu Yun looked at his palm and said slowly.

Murong Wan'er looked around vigilantly, and said in a deep voice, "Let's go, here, it's a little weird."

"Hmm" Mu Yun nodded slightly, but just as the two of them turned around and were about to leave, they heard a sound behind them, and then, before the two of them turned around, a weak and old voice sounded, "Don't go, help me"

"Who?"

When the two heard the sound, they quickly turned around, and at this moment, the place in front of them, which was originally pitch black, instantly lit up with green light, and this light, compared to the pale green light before, was many times brighter, and with this light, the two of them could also see things in front of them......

When they could see it clearly, they were both shocked, there, on a stone wall that could not see the edge at all, hundreds of iron cables were entwined horizontally and vertically, and the most conspicuous thing was that in the middle of the iron cable, an old man covered in green light, thin as wood, with messy and dirty hair and beard, seemed to be tightly embedded in the stone wall, unable to move......
