Chapter 939: Void Stone
The problem that seemed difficult to solve was unexpectedly solved so easily. Wu Yan felt very relaxed at the moment.
When Wu Yan was cultivating the blood-sucking demon vine, he had studied some growth characteristics of demon vines or demon plants. In the current world of immortal cultivation, demon plants are almost extinct. This is not because there are no demon plant seeds, but because demon plants have lost the space for growth and advancement.
These things are special creatures that can only survive and advance in the Great Wilderness World. It is naturally not easy for them to survive in the environment of the immortal cultivation world.
In the past, Wu Yan had seen some demon plants in the Five Water Cave Heaven. At that time, he had suspected that all this seemed quite strange. Previously, in the Wuliang Xumi Cave Heaven, Wu Yan cultivated the blood-sucking demon vine with the blood and corpse of sea beasts, and he had thought of these.
Now looking at the forbidden land of fierce beasts, Wu Yan has a clear understanding of the specific space for the growth of demon plants. Only in this special environment can demon plants or fierce beasts grow well.
The energy they need to advance is too huge, and things in ordinary places can't satisfy them at all.
It took less than a moment for the sixteen blood-sucking demon vines to devour all the sword-toothed grass demon essence crystals here. They look quite weird and scary at the moment.
The house-sized rhizome is covered with dense blood-red sword-toothed grass leaves, and the four vines are also covered with this kind of sword-toothed grass leaves, making them look like a group of tentacle monsters that can run.
Wu Yan's consciousness moved, and the sixteen blood-sucking sword-toothed demon vines immediately opened the way for him, allowing Wu Yan to enter the Chixia Valley smoothly.
The entire Chixia Valley, with a radius of about a thousand miles, is like a huge sinkhole, located between the mountains.
In the valley, from top to bottom, there are charred rocks everywhere. At the bottom of the valley, there are densely packed black crystals, which look like a mountain pit covered with black gems from a distance.
Wu Yan's spiritual sense swept through the entire valley carefully, but he did not find what he was looking for.
Originally, he thought that there should be at least one ordinary fire vein at the bottom of the valley, otherwise the red cloud beast would not have placed its nest here.
Unexpectedly, the facts were not as he expected.
However, after Wu Yan's spiritual sense swept through the entire valley, he also found some abnormalities. It turned out that the power ban that appeared in the entire valley was emitted from the black crystals at the bottom of the valley.
Wu Yan had never seen this kind of strange crystal before. Out of curiosity, Wu Yan could not help but carefully go down to the bottom of the valley and picked up a black crystal to examine it carefully.
However, no matter what means Wu Yan used to examine these black crystals, he could not see any origin at all. These black crystals carry a very strange energy source. Wu Yan knew very well that this energy source was the source of the power ban in the valley.
After a careful count, there were tens of thousands of these black crystals in the entire valley. These crystals, some as big as a human head, and some as big as a millstone.
Although he didn't know the origin of these black crystals, Wu Yan instinctively realized that these black crystals must have a great origin. When he encountered good things, Wu Yan would naturally not be polite.
He immediately took out a storage ring and put the black crystal as big as a human head into the storage ring.
Unexpectedly, a strange thing happened at this time. No matter how he controlled it with his mind, the crystal in his hand did not react at all. The green light on the storage ring was involuntarily bounced away when it encountered the power ban emitted by the crystal.
"Hey, what a strange power ban, it can't be collected by the storage ring!"
After a slight pause, Wu Yan raised his palm and swept it, and a green light lit up on his palm, covering the crystal.
Unexpectedly, the same thing happened again. The green light shot out from his green clam shell spiritual treasure was also unceremoniously bounced away by the power ban on the crystal.
Now Wu Yan finally showed a moving expression.
The only items that cannot be collected by the storage ring or storage magic treasure, besides ordinary large and stupid objects, are some materials or secret treasures with special functions.
Just like the Great Wilderness Shengyuan Mountain that Wu Yan had collected in the Great Wilderness Yuan Ding Hongmeng World, this special treasure cannot be collected by any space magic treasure.
Of course, these black crystals are naturally not comparable to the Great Wilderness Shengyuan Mountain, but no matter what, these crystals should also have some special functions, otherwise it would be impossible to be collected in the storage space.
After a slight hesitation, Wu Yan took out the Great Wilderness Yuan Ding again, and with a slight movement of his mind, he summoned the Cave Heaven Spirit Realm. He threw the black crystal in his hand into the Cave Heaven Spirit Realm.
This time, there was no phenomenon of being unable to collect. But what Wu Yan absolutely did not expect was that when this black crystal entered the Cave Heaven Spirit Realm, strange things happened again.
After this crystal stone entered the cave spirit realm, it suddenly flashed a black light and then mysteriously disappeared, leaving no trace or dust behind.
Wu Yan was suddenly faced with this change, and his face immediately showed a ghostly expression.
Without thinking, he immediately covered the entire cave spirit realm with his spiritual sense and checked it out. Zhuang Shan Gui and other mountain gods seemed to be alarmed by the sudden changes in the cave spirit realm. At this time, they all gathered at the entrance of the cave spirit realm. After bowing to Wu Yan, they asked: "My Lord, what did you do to the cave spirit realm just now? Why did I suddenly feel that the cave spirit realm has expanded a little, and the rules have also changed a little from before."
Hearing Zhuang Shan Gui's words, Wu Yan's whole person suddenly showed an extremely stunned expression. In an instant, it was like an epiphany, and he finally realized what was strange about these black crystals.
Wu Yan ignored Zhuang Shan Gui, but grabbed another black crystal, and then forced open the Yuan Shen God Eyes to explore the black crystal in his hand.
After a moment, Wu Yan's face showed a look of sudden enlightenment, and then he laughed out loud.
"So that's how it is! This time it's really a big deal!"
Wu Yan had no hesitation at all. He immediately opened the entrance of the cave spirit realm, aimed at the entire valley, and began to frantically collect these black crystals into the cave spirit realm.
At this moment, Zhuang Shan Gui and other cave gods were stunned.
See, black light flashed continuously and rushed into the cave spirit realm. Then, after absorbing these black light, the space of the cave spirit realm, which was originally only thousands of miles in radius, began to expand rapidly at a speed visible to the naked eye.
In all directions, the space was constantly expanding, and with the expansion of the entire cave spirit realm space, the world rules within the entire cave were also quietly changing.
Although the change was weak, Zhuang Shan Gui and other mountain gods, who had basically adapted to the rules of the entire cave spirit realm, could still distinguish what these changes meant.
"Good, good, good! Hahaha, I didn't expect that the Lord could find a treasure like the 'Empty Realm Stone'! No wonder I felt that the cave spirit realm seemed to have grown larger. It turned out that it was because of the 'Empty Realm Stone'!"
Wu Yan had no time to talk nonsense with Zhuang Shangui at this time. His attention was attracted by the large amount of black crystal stones in front of him.
Wu Yan now had to take away all the "Empty Realm Stones" here as soon as possible, otherwise it would be troublesome when the Chixia Beast reacted or other fierce beasts sensed the changes here.
After a few moments, when Wu Yan collected nearly a quarter of the "Empty Realm Stones" at the bottom of the Chixia Valley, he realized that the cave spirit realm in the Great Wilderness Yuan Ding had expanded from the original size of thousands of miles to tens of thousands of miles.
However, at this time, the "empty boundary stone" that was collected into the cave spirit realm was no longer like before, turning into black light, being absorbed by the cave spirit realm, and turning into cave space, but fell into a corner of the cave spirit realm.
In other words, his cave spirit realm seemed to have reached saturation at this time and could no longer increase a bit.
Wu Yan had no time to pay attention to these at this time, but just kept frantically collecting the "empty boundary stones" on the ground into the cave spirit realm.
Just as Wu Yan was constantly collecting these "empty boundary stones", a dull and extremely angry beast roar suddenly came from thousands of miles away. Listening to the sound, it seemed to be emitted by the red cloud beast.
The roar of the red cloud beast was full of unconcealable anger and murderous intent. It seemed to have sensed that its nest was changing, so it roared angrily towards this side.
However, the hunting team had already trapped it in a large formation, making it impossible for it to break free from the formation. Therefore, its furious roars, although louder and louder, could not break out, so that it sounded full of resentment and anger.
Hearing the roar of the Red Cloud Beast, Wu Yan's men became more and more crazy, almost without any pause, picking up the "empty boundary stones" on the ground and throwing them into the cave spirit realm, without caring where these "empty boundary stones" were thrown.
Fortunately, Zhuang Shangui and other mountain gods and land gods were all there at this time, and without Wu Yan's instructions, they took the initiative to take on the task of picking up and placing these "empty boundary stones".
Half an hour passed unknowingly, and all the "empty boundary stones" within a radius of more than 100 miles at the bottom of the valley had been collected by Wu Yan. Wu Yan breathed a sigh of relief and put away the Great Wilderness Yuan Ding without thinking.
After doing all this, Wu Yan once again scanned the entire valley with his spiritual sense, and found that there was no other valuable things at the bottom of the valley. Wu Yan then carefully withdrew from the valley.
After collecting the sixteen blood-sucking sword-tooth demon vines, Wu Yan flashed to the outskirts of Chixia Valley, and his eyes swept over the Yin-rotten mud in the mud ditch.
These rotten muds did not seem to have anything special, but they obviously had extremely terrible and sinister corrosive power. If they could be taken away, they might have other uses. However, after thinking about it, Wu Yan could not find a suitable thing to collect.
He had previously observed that the iron accountant had taken away some Yin-rotten mud. What he used was an extremely strange gourd. In that gourd, it seemed that a large number of terrible demons and ghosts were collected. And it was not the gourd that collected the Yin-rotten mud, but the demons and ghosts in the gourd.
Each of them only grabbed a fist-sized ball of Yin-rotten mud, and it seemed to have reached its limit, and they screamed miserably because of the corrosion of the Yin-rotten mud. Wu Yan did not have such a strange thing, so he could not collect it.
After thinking about it, Wu Yan decided to give up the corrupt mud and fly directly towards the barren mountains.
