While the demon dragon was talking to the burly figure, Sun Yun and Chensha explored the seemingly boundless karst cave.

After this exploration, I found that this cave is not boundless, but the walls are covered with moss, and from a distance, it looks like an infinite space.

In desperation, the two returned to the wall where the figure had disappeared.

"Uncle Chensha, I think we should go back the way we came, the shadow may be true because we are dazzled, even if this world is magical, there will never be creatures that can pass through walls. Sun Yun said.

Cinnabar shook his head and said: "The young master is wrong! If you think about it, the blue light emitted by the dragon's eyes cannot be something that exists in this world, but these things just appeared in this strange place, but they were met by you and me, and this world is not only between people, but between people and animals, and the things they experience are all fateful." ”

Hearing this, Sun Yun nodded and said, "Uncle Chensha is right, since entering the former site of the Demon Dragon, that trace of weirdness has lingered in my heart. ”

"Young Sect Master, let's rest for a while and explore again, if there is no result, then according to what you said, return the same way, the old site of the Demon Dragon is a hundred acres wide, and all we are involved now is two palaces. Cinnabar said.

Sun Yun nodded and said, "Okay, this time let's go separately!"

But just as the two of them were about to leave, a shadow with a slight breeze whistled behind them.

This time, the two of them felt it really, and they didn't have time to speak, so they tracked directly in the direction where the figure had fled.

The speed of that figure was extremely fast, and even a master of the Earth-Shaking Realm like Cinnabar spread out at full speed, and gradually lost the trace of this guy.

Fortunately, the white wolf's speed seemed to be much faster than the shadow, and it bit behind the shadow, knowing that after coming to a huge stone pillar covered with moss, the shadow dodged and disappeared into the stone pillar again.

The white wolf stopped, although this guy is a beast, he will never be stupid to hit the wall.

After lingering here for a while, he saw the figures of Chensha and Sun Yun chasing after him in the distance.

Before and after coming closer, Sun Yun stroked the head of the white wolf and said, "White wolf, where did the shadow go?"

The voice of the white wolf appeared in Sun Yun's sea of knowledge.

"Master, the figure disappeared into the pillar. The white wolf said humanely to the pillar in front of him.

Sun Yun glanced at the white wolf in surprise and asked, "Are you sure, that guy disappeared into this pillar like last time!"

The white wolf nodded with certainty and said, "It's true, the master actually didn't misread it last time, according to my own thoughts, this pillar must have a mechanism." ”

Sun Yun patted the white wolf's head appreciatively.

Then he said, "Uncle Chensha, the white wolf said, and the shadow disappeared into the pillar. ”

Chensha was very surprised and glanced at the pillar in front of him and said, "This pillar doesn't look like it's hollow, how did that figure disappear into it!"

"How to disappear, let's go forward and find out!" Sun Yun finished speaking, tentatively touching towards the pillar.

Seeing this, Chensha stopped Sun Yun's behavior.

He said quite cautiously: "Young master, don't worry, don't worry about it, in such a situation, remember not to experiment in person, I think we should use stones instead of them like before." ”

When Sun Yun heard this, he nodded approvingly and said, "Okay, just according to what Uncle Chensha said." ”

After searching for a moment beside the pillar, Cinnabar found a long stone and weighed it in his hand with great satisfaction.

When Sun Yun saw it, he asked a little puzzled: "Uncle Chensha, your dagger is not much different from this long stone, why don't you use a dagger?"

I saw Chensha smile slightly and said: "Young Sect Master, I will give you another piece of advice, weapons and magic weapons are also indispensable things, and these things cannot be easily used to make risks unless it is absolutely necessary." ”

When Sun Yun heard this, he laughed and said: "This is the first time I have heard of this kind of suggestion, Uncle Chensha can rest assured, Sun Yun has written it down." ”

Cinnabar smiled and didn't say anything more, but took the long stone and struck it on the stone pillar.

"Bang bang......" A dull voice came, and Cinnabar also had his own judgment.

"Young Sect Master, this stone is completely solid, and it is impossible to enter it. Cinnabar said.

"No, I believe that the white wolf saw that this time it was close behind, it was impossible to be mistaken, there must be a mechanism in this!" Sun Yun said.

After Sun Yun finished speaking, he directly reached out to touch the stone pillar, and as soon as he touched it with his hand, he directly found the abnormality.

The moss looks like moss, but it feels cold metallic to the touch.

Sun Yun grabbed hard at the pillar, and layers of green powder were scattered all over the ground.

This time, the full picture of the pillar is fully revealed.

The pillar was made of the same material as the bronze man, and was made of bronze.

In this way, Sun Yun has a correct understanding of the entire karst cave.

Where is this karst cave, this is clearly a bronze cave.

Sun Yun was about to continue his search, but at this moment, something in his backpack suddenly moved.

Such a scene directly pulled Sun Yun's thoughts back to the scene when he went to Shushan alone, also in a dark underground passage, also in his backpack, and the same item was summoned.

Last time, it was the ancient scroll, and this time it was the iron box left by the grandfather.

Sun Yun looked at the iron box that shook slightly in his hand, and there was a strong struggle in his heart, whether to open it or not.

Although there is no threat from Aeolia at the moment, Chensha beside him is not someone Sun Yun completely trusts.

In addition, in such a situation, in such an environment, if you open it rashly, you don't know what kind of crisis it will cause.

But the sound and speed of the box's vibration are getting faster and faster.

Until a certain moment, it was uncontrollably suspended in the air, smashing towards the bronze pillar beside Sun Yun.

This sudden change made Sun Yun and Cinnabar have no time to react.

But in Cinnabar's eyes, when he saw the box, his eyes flashed with a hint of vague longing.

But it was fleeting, and Sun Yun didn't notice it.

Both of them were caught off guard and allowed the box to smash into the bronze pillar.

But the moment the box came into contact with the bronze pillar, the box disappeared out of thin air.

Sun Yun was shocked when he saw this, this box was more important than his life in a sense, this time he didn't hesitate anymore, he directly unfolded at full speed and rushed towards the bronze pillar.

Chensha stood aside, this time he didn't stop it, and it could be regarded as acquiescing to Sun Yun's tentative behavior.

When Sun Yun came into contact with the pillar, he disappeared into the void like the box.

All this was seen in the eyes of the white wolf, which made it rush directly to the pillar and disappeared.

Until this time, Cinnabar also let go of all hesitation, flashed, and disappeared into the void.

After the two of them and the wolf disappeared, the burly figure gradually appeared next to the pillar.

I couldn't see his appearance clearly in the dark, so I only heard him whisper: "Boy, whether or not you can embark on the great cause of cultivating the truth depends on this level!"

With that, a shake disappeared into the infinite darkness, and the identity of this person was really a mystery.

Speaking of Sun Yun, after experiencing a whirlwind of the world, Sun Yun slowly opened his eyes.

When he saw the scene in front of him clearly, he couldn't help but be taken aback, only to see hundreds of chains with a diameter of nearly two meters rattling above his head.

Sun Yun couldn't help but sigh in his heart: "What is such a thick chain for?"

However, he didn't think deeply about it, and the top priority was to find the box first.

The box was inspired, and after entering, it must have flown towards the inspiring thing, and Sun Yun simply followed the direction in which the chain went deeper.

Along the way, he called out to Chensha and the white wolf several times, but never got a response.

And as the chain deepened, Sun Yun could feel a sense of oppression, this sense of oppression was very real, and it became stronger and stronger as he went deeper.

Until Sun Yun came to the edge of a cliff, this sense of oppression directly made it difficult for Sun Yun to move forward.

Sun Yun was amazed in his heart, and directly urged his true qi and inner armor to resist this oppressive force.

This inner armor really had a miraculous effect, so it forced Sun Yun to take another fifty steps or so.

It wasn't until he stood on the edge of this cliff that he lost his effect, and Sun Yun couldn't take a step forward when he got here.

But the scene at the bottom of the cliff shocked Sun Yun speechless.

I saw a bronze coffin the size of a football field being bound by countless chains that were so thick that they were suspended in mid-air.

Through the light around the coffin, it can be seen that the space where the bronze coffin is located is a very regular cylindrical deep hole, and when you look down, you can't see the bottom.

On this coffin, it is engraved with the same runes as the previous hall.

However, for some reason, these runes were much dimmer than the runes on the top of the hall, and in some places they had even lost their luster.

Sun Yun watched quietly like this, he didn't know what to do, and it was difficult to move forward.

But when he tried to retreat to the rear, he found that he could not move either.

In desperation, Sun Yun greeted Chensha and the white wolf a few more times, but the voice of this person and a wolf still did not sound.

In desperation, Sun Yun had to look at the mysterious and huge bronze coffin again.

It wasn't until his eyes scanned the center of the bronze coffin that Sun Yun found that the box that flew out of his hand actually appeared there.

The box falls impartially in the center of the bronze coffin, and if you look closely, you can see that part of the box has been embedded in the bronze coffin.

Could it be that what my grandfather really left me was the things in this bronze coffin, but if this is the case, what is in that box, Sun Yun wondered in his heart.

Just when Sun Yun was puzzled, the huge bronze coffin suddenly trembled, and an overwhelming pressure came, directly causing Sun Yun to spurt out a mouthful of blood and faint.
