It didn't seem to be a long distance, and after flying for a few months, Zheng Zheng and the others finally saw what the luminous body looked like.

It resembles a big heart, but it's made of stone. The lines on it are clearly visible. If you think about it, it's like a blood vessel meridian. The only thing that is bad is that there is no blood supply that beats like a real heart.

"It's too similar. Poppy said in surprise.

"yes, it's too similar to the heart. The Demon Butterfly also exclaimed with a face full of amazement.

The whole stone heart is at least 10,000 miles high, and the closer you go, the more it looks like a bare mountain.

"Let's go up and have a look. Two hours later, Zheng Zheng took the lead in stepping on this strange stone body, walking on it is hard, as hard as granite, each of which is like a meridian, now it seems as unfathomable as a tunnel canyon.

"We looked around and saw if we found anything. Zheng Zheng searched separately with several flower girls, the stone body was as hard as gold, like a tunnel of blood vessels extending in all directions, everyone was busy for a long time, but they couldn't find any useful clues.

"Young master, it seems to be a big rock here, and there is nothing here. Poppy said a little discouraged.

"Yes, young master, I don't have this direction, but this stone body is a good material. I just tried it, and I found that it was harder than I had ever seen in my life, harder than all the defensive magic weapons I had ever seen. ”

"Young Master, should we get some stones to refine magic weapons, they must be very powerful. "Rose red touches here and there, and her eyes are full of small pink stars.

"Haha, this stone mountain is a whole, there is not even a bit of stone dust, I see what you can do to knock down a stone from here. Zheng Zhengle said with a smile.

Mei Hong looked at it, tried to dig a few more times, and couldn't help but become frustrated: "Young master, don't you guess so accurately every time?"

Seeing that Mei Hong was very depressed with her small mouth, the demon butterfly couldn't help but giggle and said: "Hehe, it's not the young master's guess, it's his careful observation, if you have a snack, you won't make that joke just now." ”

Mei Hong felt very embarrassed after hearing this, and she was a little twisted and pinched.

After Zheng Zheng smiled, his face gradually became solemn and said: "This stone heart must be the key to our exit from this chaotic space, there should be a certain node in it that we haven't discovered yet, so I hope you will take a little effort, look for more, take a look more, maybe there will be new discoveries." ”

"Yes. ”

Zheng Zheng didn't know that it took ten years to find and see.

I have walked through every piece of land here, and I have walked through every corner of the heart of the stone, but there is still no harvest.

Everyone was a little numb and desperate.

On this day, Zheng Zheng, Lingmei and others returned empty-handed again, and everyone's mood was a little low.

Poppy smiled a little reluctantly and said: "Young Master, maybe there is a problem with the direction of our thinking, and we haven't found the direction to solve the mystery of the heart, I don't think you want to get together to discuss it?"

Demon Butterfly was a little angry and said: "Sister Poppy, we have been discussing this matter for ten years, do you think you can discuss anything famous?"

Zheng Zheng frowned and said: "I think the most important thing is to solve the mystery of this stone first, as long as you can figure out what the stone is about, I think it is easy to find a way to leave." ”

"What the young master said makes sense, but the key is that over the years, we have traveled all over the stone heart, and even the tunnels that are as dense as spider webs have been checked, and we can't find any suspicious things and records. ”

Zheng Zheng shook his head slowly and said, "Maybe there is no record here at all, but I have a very strange idea recently, which seems to have a little bit to do with my imminent refining of the Purple Mansion Yuanying." ”

"What do you think?" the crowd hurriedly asked.

Zheng Zheng pointed to his chest and said in a deep voice, "Heart." ”

"Heart?" the crowd was in a fog, and some of them couldn't figure out what it meant.

"You see, this stone heart is exactly the same as a real heart in terms of appearance and structure, the only difference is that it can't beat and supply blood. I've been wondering these days, if we were given some kind of energy, could we make it beat like a heart?"

"Uh......" The girls were stunned for a moment, and were stunned by this whimsical idea. But when I come back to my senses and think about it, there is really a little bit of truth. The whole scene suddenly became enthusiastic, and Poppy said with great interest: "Young master, then what method can you use to make this big heart beat?"

This question stumped everyone at once, and the Demon Butterfly suddenly thought: "Young Master, we have set up a few large arrays inside the core of this heart, do you think this will work?"

"Sister Butterfly, what kind of formation?" Mei Hong said curiously.

"Uh......" Demon Butterfly squeaked, "I want everyone to think about this again......"

"Back then, under the arrangement of the young master, my sister learned the puppet technique in the fire altar space, and also got a lot of puppet crystals, can you use the puppet technique to make this heart move. At this time, Jian Lan spoke.

"I think it works. Gui Fang's eyes lit up, and he hurriedly spoke to Zheng Zheng.

"And you see the silver light emitted from the stone, it seems to be full of some mysterious and unknown power, although we can't use it. But can we transform this silver light into a driving force for the heart to beat again?"

"I think this method can be tried. Lianhe said excitedly.

Everyone worked together to make a general framework for Zheng Zheng's vague idea, and it seemed very feasible.

Zheng Zheng pondered for a long time, and then slowly spoke: "If you want to place a magic circle in the center of the earth, this is an extremely huge and vast project. And if it works, we don't know yet, but it's always boring here, so try it, maybe there will be a hint of life. ”

The young master decided to try it, and all the girls naturally mobilized.

You must know that the heart of this stone is so big, there are more than 100,000 hectares up and down, and how many materials and manpower will be consumed to place the magic circle?

Next, not only all the flower girls in the space were dispatched, but even a dry demon beast was summoned to carry materials, draw spells, forge array weapons, design formation diagrams, and so on.

The preparatory work alone took three years.

Subsequently, it took another ten years to place the various formations in the design position. Now the entire stone heart inside and outside, 108,000 formations of different sizes have been laid out successively, connected before and after, communicating up and down.

This is not completely over, the core driving array eye, that is, the inner position of the stone core, is also ready to start construction.
