Ignore Alang, Chen Chu turned around and said, "Give me all the oxygen, you guys go out and wait first."

"What are you going to do?" Alang asked.

"It won't take much time to find something." Chen Chu said this, and he had already started to snatch the oxygen cylinder hanging on Alang's left shoulder.

"One has been enough for a long time."

"Give you here!" Chen Chu pulled him down: "Uncle Master, give me yours."

Uncle Master frowned and took off the oxygen cylinder: "Don't you need help?"

"Need not."

Then it's Qi Yue's.

Qi Yue was too lazy to say anything, so she took it down and threw it to Chen Chu. It seemed that she was deliberately trying to put it on Chen Chu's face, but unfortunately Chen Chu caught it.

In the middle layer, the front and back are connected. Judging from Chen Chu's posture, he seemed to have to circle around it. He didn't say anything he wanted to find.

After they walked out, they told Qi Xuan that Chen Chu had walked in.

Qi Xuan said in confusion: "What does he want to do?"

"Who knows. But, adoptive father, you can rest for a while."

The situation inside is a circle, so there will be no such thing as getting lost. At that time, Chen Chu will come around, make some noise inside, and help him come out. So Qi Xuan withdrew his hands.

He did not really destroy this iron plate, but only suppressed its regeneration. Not long after it was reclaimed, the metal returned to its original state.

Chen Chu walked inside for more than 10 minutes and came to the quarter part.

He could feel the temperature rise significantly.

He took a shovel and dug the rocks. The rocks here were very hard! The soil was dry and steaming. After a while, Chen Chu was sweating all over. At least he knocked out a pit and took out a dagger to dig it. Soon, Chen Chu dug through this part.

Flashes of red light were printed on Chen Chu's face, and his eyes looked out through the hole. Both eyes were stinged, the same as the water flow, and there was also an energy surrounding it, isolating everything outside. However, at this time, it was felt more clearly than at the water flow that this layer of energy was absorbing the huge energy emitted by the lava outside.

Putting away his things, Chen Chu continued to walk forward.

Before leaving, a piece of gauze was removed from the backpack and tied a stone and threw it on the ground.

To another quarter point, Chen Chu did the same thing.

On this side, the water flow was found, and the situation was no different from the first point. Next, the last unexplored side was the center of the earth.

It took Chen Chushao to walk this round for four hours. The main reason is that he spent a lot of time digging.

"The water flow and lava outside provide this layer of energy support." Chen Chu felt that this was the conversion process of natural energy, which was extremely similar to the familiar rune conversion process. In this space, is there a core rune array? He thought so. If destroying this array, can it solve the embarrassing situation of being trapped here? But if you think that this may directly destroy the structure of the entire space and lead to the destruction here, Chen Chu was a little hesitant.

Above the compartment space, there is an unknown field.

Chen Chu looked up and looked at it. Judging from the internal and external structure, if the above is the core, will it form a connection with the internal sand and dust fluctuations? It is like an internal switch.

But... it was a bit difficult for Chen Chu to climb up. Moreover, Chen Chu, who had almost been steamed after passing the two parts of the lava, had a lot of moisture flowed away from his body.

The decision was not difficult, Chen Chu returned to the initial point and planned to go out for a rest first.

After a loud knock, Qi Xuan opened the door and let Chen Chu go out.

Taking off the oxygen hood, Chen Chu sat on the ground panting. After sitting down, sweat was penetrated by sweat.

"What did you find?"

"There may be a device that opens the outside layer." Chen Chu did not say the rune group because this would cause problems that were difficult to explain to them.

"You can go in after closing?" Alang asked hurriedly.

"Well. Dabai told me that there is a way out along this side of the water flow. Therefore, if you can solve the energy of isolation, you can return to the ground."

"Then have you found the device?"

Chen Chu raised his hand and pointed at the top of his head: "Go up and go to the outer top of the internal structure. I guess it's there, it should be right." He said inconclusively.

"Is there any point?" Alang asked suspiciously.

"It should be because, outside water flow and lava are the basis for the operation here, and the energy they provide. Sand and dust may be subject to a kind of adsorption force, which is most likely at the upper end."

"And lava!?"

“Two sides of a quarter.”

The few people were moved and had a deeper understanding of this incredible place.

Chen Chu sat down and rested for a while and said, "I have to go up."

The uncle looked up and looked: "The height is about 300 meters, and the rope we brought in is enough."

In short, this means “Can you climb up?”

The part of the rock inside is uneven, so it is not difficult to climb. It is just that the floating has become a negative angle, which is somewhat difficult: "It can be done." Chen Chu did not hesitate about this.

So, the rope was given to Chen Chu. Uncle Master thought about it and decided to follow Chen Chu up.

Chen Chu just used a bottle of oxygen, and now it is not enough for more people to follow him, so he and his uncle.

The advantage of having uncle follow him is that Chen Chu doesn’t have to work too hard, and uncle can drag Chen Chu alone.

In this way, it is much faster than expected.

It took less than an hour to reach the top.

The situation was the same as Chen Chu imagined. There was something on it, but it was actually this thing. I didn't expect it. I came up and didn't dare to get close!

The ball is obviously much smaller than in the building, but it also contains that huge energy. If you touch it, you might be as Alang looked like at that time: "We have to let them close the balance below first."

Uncle Master didn't expect Chen Chu to go down to do this, so he nodded and left.

Leave Chen Chu and look up and down.

The ball in front of you is the one that attracts people's attention.

Uncle Master moved very quickly, as if it had not been in 10 minutes. The light of the ball dimmed. Obviously, the balance outside was turned off.

After the light emitted by the ball disappeared, Chen Chu used the flashlight to shine around, and maybe there was something like a white-faced here. If you observe the movements around like this, you will naturally find the strangeness that comes with it. On the ground, there are four... flowing pipes connected to the ball one after another.

Chen Chu walked up to a front, squatted down and looked carefully. What was flowing here seemed to be energy. This was a manifestation of materialization. In this way, Chen Chu couldn't help but sigh, "They have completely mastered the use of these energy. Does the so-called new world mean this system that can be added with simple and clear?" It is not difficult to guess where these energy comes from. It should be to absorb the energy of peripheral lava and water flow. This is the process of introduction and storage. The excess energy collected by natural factories.

This is energy harvesting that does not destroy the ecological system.

The eyes were looking at the sphere, "This thing is the device for this natural cycle, conversion..."

Standing up and walking forward, Chen Chu raised his hand and groped carefully. There was a faint residual heat on it, and the energy that had just started diffuses very fast.

This kind of exploration made Chen Chu feel that there seemed to be many small holes on it. The uneven feeling. In fact, there were also the ones below, but Chen Chu stepped on it and didn't feel it carefully.

Dabai, who followed Chen Chu, suddenly jumped onto the ball.

The diameter of this sphere is about 3 meters, which is much smaller than the one below.

At this distance, Chen Chu clearly saw what Dabai was doing on it.

His butt was facing Chen Chu, and his paws were picking something.

Chen Chu didn't say anything when he saw it.

Not long after, Dabai turned around and meowed at Chen Chu.

Chen Chu climbed up.

Dabai opened a hole.

The structures of the two balls seem to be somewhat different, and the one below does not have such a lock.

There is a pull-up handle in the latch.

With a grasp, Chen Chu pulled up hard.

The sound of "kkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkk

And the ball begins to loosen.

Chen Chu didn't use all his strength. At this point, he suddenly raised it up!

The sound of "touch~~" was a bit messy.

The entire sphere disintegrates, like a flower that is about to bloom.

Chen Chu, who was standing in the center, was on a small platform.

And inside this ball, there was a ball of black stuff.
Chapter completed!
