There was the aura of the Sky Robbery Pearl in all directions, and there were quite a few of them. Duolai was a little confused. Are there so many of these things? But he soon discovered that these auras were all in the surrounding walls.

The energy of the wizard tower is very strong. He took a rough look and found that the scanning range was about two thousand meters, and within these two thousand meters, there were four sources of fluctuations.

The problem is that these fluctuations are too deep. He sensed them and found that the nearest one was in the wall more than 200 meters away from him. It would not be an easy task to dig them out.

He coughed and said, "We may have to take a shortcut and go through the wall. I sensed the aura of many Void Tribulation Pearls, but they are not in the passage."

"All in the wall?" Ash asked puzzledly.

Dole nodded and pressed his hand on the wizard tower. The wizard tower emitted a yellow light and blended into the surrounding world without any hindrance. Dole also breathed a sigh of relief. As long as the yellow light could penetrate the surrounding earth, he could perform the earth walking technique.

Ashe nodded, and walked into the yellow light with Yunuo, and disappeared together.

Dolai was the only one left in the corridor. The only sounds around him were mosquitoes and bats flying through the air. It was eerily quiet.

Dolai looked around with a deep gaze, and had no interest in continuing to walk along the passage. It was too troublesome.

He raised his foot and slowly walked into the wall. The yellow light wrapped him and he disappeared into the passage.

Only after entering the wall did Dolai see the true face of this world.

This wall is not made of normal soil, but a mixture of corpses, soil, minerals, metals and other things. The interlayer of the wall is full of corpses of various animals, plants, stones of various shapes, meteorites, emitting an unknown mixed smell.

Dole thought about the true appearance of this creature. Could it be that everything in this world is a mixture of what he has eaten?

As he walked, he saw corpses everywhere, which was really shocking. He saw the bones of an animal, and the thickness of the bone alone was greater than his height.

What creatures have such strong bones? Are they all alien creatures?

At this time, Ashe and Yunuo were also stunned. This was not included in the information provided by the Glory Wizard Alliance. Is this the truth of this world?

Stones, soil, mixed with bones, make up this world, which is simply amazing.

As Duolai walked towards the direction of the Sky Robbery Pearl, he looked at the ground around him in shock. After looking for a while, he suddenly said excitedly, "We may really get rich this time."

Ash's heart moved, and he asked, "Are you talking about these bones?"

Duolai said excitedly, "Yes, anything that can be eaten by extraterritorial creatures must also be extraterritorial creatures. The bones of these extraterritorial creatures are very hard and can be used as very good raw materials. I remember there is a wizard tower called the Turin Bone Tower, which is even more bizarre than the Tower of Babel. It has very powerful abilities. Although it cannot travel through the void like the Tower of Babel, its texture is indeed harder than the Tower of Babel, and it is absolutely effective in hitting people with it."

Yunuo was a little confused when he heard this, "Wizard Dolai, even if most of the raw materials are bones of various creatures, other materials must be very valuable too."

Dolai waved his hand nonchalantly, "Other materials are just extras. The most important thing is the strong bones of living things. With my current strength, as long as the bone materials are sufficient, the other things don't matter. The Tower of Babel cannot be upgraded to level eight because of the space materials, but the Turin Bone Tower can. There are a lot of high-level bones in it."

Dole said a lot of things, then reached out and took a piece of bone from outside.

These bones looked inconspicuous from the outside, and could not even resist the penetration of the Tower of Babel. However, after being brought in by Dolai and placed inside the Tower of Babel, they immediately emitted a bright glow, resisting the spiritual detection of the three of them.

Dolai felt a little surprised, because in his mental perception, this power did not belong to any element, nor to any energy he had ever seen. It was essentially many times stronger than his mental strength.

Is this still the skeleton of a creature that has been dead for many years?

The three of them looked at the bones in their hands and tried to explore them, but they all found nothing.

Ash was happy now, "See, there's nothing we can do."

Dolai blinked his eyes. He had indeed never seen such a situation before. What was the nature of this energy? How to remove it or how to use it?

He thought for a moment and said, "Let's just walk and see. This space will always exist. As long as we don't tell anyone, no one will know the truth here. Most people won't come here."

At this moment, Duolai had already walked to the front of the first Void Robbery Bead. He raised his hand and dug the soil where the bead was.

After washing it clean, it becomes a new Kongjie Pearl.

At this time, Duolai discovered that each Void Robbery Bead was different. The Void Robbery Beads found in the wall obviously had much stronger spatial fluctuations, and the magic patterns inside were very complicated. It took him a while to see the door inside.

He thought about it and since he had nothing to do now, he simply separated a part of his mental energy and took the Void Pearl to the Wizard Tower to start analyzing it. As an alchemist, the most basic thing was to analyze matter, and Dolai couldn't sleep until he understood what was inside.

In the wizard tower, a purely transparent light and shadow condensed. He held the Sky Robbery Pearl in his hand and placed it on various instruments to begin testing it.

Seeing this, Ai Xi joined in the fun. Although she is now a biological pharmacist, she can also do some research in this area. Yunuo came over directly, watched Dolai's movements, and took the opportunity to learn from him.

Seeing the two people coming, Duolai put down the light in his hand and did not hide his incompetence, but patiently explained.

"When you get a new item, the first thing you should do is scan its general functions. Don't activate it before confirming its basic capabilities, otherwise there will be trouble. For example, if you activate something that has the function of a bomb, it will explode."

"Also, if you are trying to confirm the other party's main purpose, it is best to put them in a closed space and use mental power to remotely control the equipment to scan. Don't do such dangerous actions if your real body is fine."

"We have no previous experience with this kind of space product, so we'd better scan it from the outside to see the composition of the magic pattern. After determining the function of the magic pattern, we can roughly guess its function. If there is no danger, we can activate it to see what it does and study its nature and capabilities."

Duolai explained and observed at the same time, which took a long time. While doing it, he took the other several Kongjie beads in his hands.

The underground area of ​​this world is very vast. Every few meters, there is a passage leading to an unknown place. After Duolai got the Void Robbery Pearl, he encountered other Void Robbery Pearls in the range of other Void Robbery Pearls. He simply did not go forward along the passage, but followed the general range, went through the wall directly, and wandered around in the land.

As he walked, Dolai looked around and even brought in some soil to take a look.
