The inaudible sound of mechanical rotation echoed in the hall, and the Rubik's Cube kept spinning on the shelf, and it was spinning without a trace of regularity, which made Wang Yan dazzled for a while.

"En!" Wang Yan vaguely saw that when the countless small metal pieces on the Rubik's Cube were constantly swirling, some golden runes gradually appeared.

Finally, the whole Rubik's Cube was spinning more and more slowly, which made Wang Yan's mood a little nervous, and he didn't know what the so-called Great Realm Grand Prize was......

"Click!" swirled, and finally the Rubik's Cube stopped, "Click!" The side of those metal Rubik's cubes on this Wang Yan suddenly turned out, directly forming a fairy card magnified dozens of times, with several big characters written on it, Cave Mansion Secret Realm Card!

I saw that the immortal card was actually a multicolored streamer, and the attribute pattern of the immortal card on it was a multicolored spiritual gem, and in the middle was a small building-like pattern......

Follow!

"Whew!" A burst of multicolored spiritual light flew out of the Rubik's cube and landed directly in front of Wang Yan, only to see a multicolored spiritual light flashing, and the cave secret realm card appeared on Wang Yan's hand......

"Cave Mansion Secret Realm Card? What kind of card is this? Is it Cave Mansion?" Wang Yan looked at this immortal card over and over again, and couldn't help but say in surprise.

"Oh! It's a cave secret realm card! This is a good thing!" Hearing this, the card fairy hurriedly said: "This immortal card is equivalent to a mobile cave mansion, and there is also a spiritual energy furnace in it, as long as you burn the spiritual stone, you can create a steady stream of spiritual energy, that will be good for your future cultivation! In the future, you don't have to worry about the drying up of spiritual energy!"

"So good!" Wang Yan said happily when he heard this, his voice paused, and he suddenly felt a little careless, and couldn't help but say: "Hey! You don't have to be so fake about the lottery, are you? You deliberately prepared it for me, right?"

"What? I didn't deliberately manipulate this lottery Rubik's Cube!" said the card fairy.

"I'm going down the mountain, you just give me a mobile cave, and you still say that it wasn't operated on purpose?" Wang Yan asked rhetorically: "Why don't you give me anything directly in the future, so why bother with it?"

"Tsk! Doesn't this feel like using the lottery Rubik's Cube, isn't it more expected?" Fairy Ka smiled: "Besides, I don't control it every time." Doesn't this mean that if you advance to a big realm, you will be given a grand prize, if the things drawn are too bad, will you beat me?"

"Forget it, whatever you like!" Wang Yan heard this, and didn't care about this detail with the card fairy, this card fairy was just too playful, and said helplessly, anyway, if there are good things, just take them. There is nothing polite to this card fairy, thinking so in his heart, he hurriedly said: "Card fairy! How to use this cave mansion secret realm card, is it the same as other fairy cards?"

"Yes, you can put it in your body, and then drive it to release it like a treasure!"

"Okay! I'll try! Let's see how your cave realm goes!"

"Wait!I'll put away my lottery cube first!" said the card fairy, and after a while, the lottery cube turned directly into a spiritual light. flew into Wang Yan's navel......

"I say, Fairy Ka. Can you fly in without your navel!" Seeing this, Wang Yan said with a smile.

"Tsk, do you want to get out of another hole?"

"Uh...... It's still the navel......" Wang Yan was stunned when he heard this, and said embarrassedly......

I don't care about this card fairy.

"Enlightenment!" Wang Yan held the cave secret realm card in his hand, there were words in his mouth for a while, his fingers pinched the trick, and the cave secret realm card in his hand turned into a burst of colorful spiritual light and surged into Wang Yan's mouth. After a while, Wang Yan only felt that there was more immortal card in the immortal card artifact, and directly turned into a small building house with colorful light swirling, and his heart moved, and he said to the card fairy: "Hey! Card fairy! This cave secret realm is too small, right?"

"Tsk, you'll know when you release it. That's a lot more than you think!" said Fairy Ka with a sigh of relief.

"Oh! I'll take a look!" Wang Yan hurriedly replied, pointing his finger and shouting, "Go!"

"Hum!" I saw a burst of colorful spiritual light gushing out from Wang Yan's hand, a cloud of colorful spiritual light surged, and a small silver house swirled in the air, and when I saw the wind, it was long, and after a while, it turned into a zhang and fell to the ground......

I saw that this house is not so much a house, but rather a tower, the first floor of this house is only three or four feet high, each layer is a fist of glazed tiles, emitting a trace of spiritual light, there are a total of eight layers, the whole is a silver metal pagoda, it does not look like a secret realm of the cave, but more like a treasure......

But!

This floor is only three or four feet high, and the entire height is only more than a zhang, it seems that it is indeed too small, not to mention an adult, even a child is a little reluctant to enter......

"Hey, Card Fairy, can't you zoom in?" Wang Yan looked at this tower, and continuously cast the mantra drive, and found that this cave secret realm could not be enlarged......

"That's for sure! Just go in and see! It's big inside!" explained the card fairy.

"Really?" Wang Yan heard this, and said in disbelief: "Then how do I have to get in?"

"You will drive the secret realm of the cave with your divine sense, and your consciousness will follow it!"

"I'll try!" Wang Yan replied, pinching his fingers and chanting the mantra, his divine consciousness moved, only to feel that his divine consciousness and consciousness were suddenly attracted by the secret realm of the cave mansion, and he couldn't help but drill into the secret realm of the cave mansion, only to see Wang Yan's body turn into a red light, and he drilled directly into the secret realm of the cave mansion......

It feels a bit like using a teleportation array......

"Here...... It's so big......" Wang Yan only felt that his eyes lit up, and a vast land appeared in front of him, full of strange flowers and plants, the whole was an independent heaven and earth, and the aura of heaven and earth in the entire space was also very strong, even more amazing than the secret room of his cave mansion......

And in front of this piece of heaven and earth, there is a huge tower, the whole is hundreds of zhang high, and the silver light is surging, which is clearly the tower that magnifies the secret realm of the cave mansion that I don't know how many hundreds......

"Card Fairy!This is the real Cave Mansion Secret Realm!" Wang Yan said with some excitement: "Is the surrounding environment real?"

"The environment around here is from the illusion...!" Fairy Ka said truthfully, "Only that tower is the real secret realm of the cave!"

"Oh! I'll go in and take a look!" Wang Yan looked around, but he couldn't see that it was an illusion at all, and as soon as the thought in his heart moved, his body didn't need to drive the flying sword, so he flew up, and flew directly towards the tower......

Wang Yan went directly to the tower, the gate was dozens of zhang high, and the figure went directly in, only to see that the first layer was a vast land, and the ground was separated by pieces of dirt soil, the whole space was very vast, and the ceiling was actually a blue sky and white clouds......

"This first layer is a medicine garden for cultivating elixirs, and if you want to cultivate here, you can do so!" said Fairy Ka.

"Medicine Garden!...... I don't grow elixir......" Wang Yan frowned when he heard this, and said lightly.

"Then go to the second layer, the second layer is a fighting arena ......!" the card fairy continued......

Wang Yan went up layer by layer, and the design of each layer was very amazing, but really, this kind of treasure didn't seem to be something that his cultivation could have......

The third layer is the secret room for cultivation, and the aura of the entire third layer is the strongest.

The fourth floor is the refining room, the treasure refining room, the secret room for refining immortal cards, and the fifth floor is the storage room, where you can put treasure materials and the like.

The sixth layer is actually a huge cage, and the card fairy said that it was used to hold demon beasts or something, but it made Wang Yan a little speechless, who has nothing to do to catch some demon beasts?

The seventh layer is a huge space, there is nothing in it, the card fairy said, this is used for some discarded, refining failed things, but there is nothing to put in it......

The eighth layer, that was the most important layer, this layer was a huge spirit stone smelting furnace with countless metal pipes, and there were huge furnaces on it, and there were treasure parts that Wang Yan couldn't even understand......

This eighth layer is the core part of this cave secret realm, the spirit stone furnace, as long as the spirit stones are introduced into those spirit stone furnaces, the entire cave secret realm can produce a steady stream of spiritual energy......

And these auras are not just the aura converted from the spirit stone, the main thing is that once the spirit stone furnace is opened, it can continuously absorb the surrounding aura, Wang Yan can take the initiative to control these auras to that place, and even convert the attributes of the aura......

After experiencing it in that cultivation secret room, the aura in that cultivation secret room is several times that of the cave he is now, so if you cultivate here, your cultivation speed will increase a lot......

But.

This spirit stone furnace needs a lot of spirit stones, if you want all the places to be full of spiritual energy, you will have to consume tens of thousands of spirit stones a day......

If you want to double the spiritual energy, you need to consume more than 10,000 spirit stones, and so on.

Of course.

There is also an upper limit, it seems that a hundred times the top will be reached, but it can't afford to kill Wang Yan.

It's just more than 10,000 spirit stones a day, and Wang Yan can't afford to consume it, this is really amazing, won't his remaining seven or eight hundred thousand spirit stones be used up in three or four months?

After doing it for a long time, this cave mansion secret realm is also a chicken rib? Of course not, Fairy Ka told Wang Yan a good piece of good news......

This cave secret realm does not mean that the whole thing is full of aura when you use it, when you use the cultivation layer, the cultivation layer is full of aura, and the aura consumed in that way is only one-eighth, and it is only one or two thousand spirit stones a day, but this day consumes more than a thousand spirit stones, which also makes Wang Yan choke enough......

In addition to him, it is estimated that there is no monk who can afford such an expensive thing, fortunately, he also has a lot of black mother iron ore, regardless of other words, if he has been using this cave secret realm, he can afford to consume it for hundreds of years, and after a hundred years, if some things go well, he may be a great monk in the Jindan period, and those thousands of spirit stones are not a trivial matter......?
