Skull Mountain, White Bone Cave, a layer...

A space crack appeared strangely in the cave. The next moment... Chu Xingyun stepped out of the space crack.

After looking around, I confirmed that it was the location I arrived last time, and then nodded.

I looked up at the top of the cave and saw... there... there is a basic rune array with a diameter of one meter.

Chu Xingyun pulled out the Sword of the Sky to see if he could dig the sportive array down.

Chu Xingyun thought very well. If he could dig out the one-meter-diameter rune formation, he could carry it with him, absorbing the energy radiated after the death of the skeleton warrior at any time, and condense the soul bones.

Unfortunately, although imagination is beautiful, reality is cruel.

Waving the sword, although Chu Xingyun accurately cut off the one-meter-diameter rune formation, as soon as he left the top of the cave, the rune formation instantly disintegrated, turning into a bunch of gray smoke and disappeared.

He shook his head in disappointment. Chu Xingyun actually knew that the rune formation was not that simple. If you want to dig it, it was just a joke.

He looked up at the original position of the rune formation. Although Chu Xingyun dug out a layer of more than 30 centimeters, the rune formation seemed to be the annual rings of trees. Even if it was cut off for a section, the same pattern was still there.

He shook his head helplessly. Chu Xingyun knew that this stupid method would not work. This is the case with the big formation. If you pull the whole body with one blow, the big formation will definitely be annihilated in an instant if you cut it with one sword.

It is actually very stupid to use the stupidest method to obtain the spiritual array.

At least, in terms of the tens of thousands of formations that Chu Xingyun knew and mastered, even the lowest-level formations could not be poached.

However, although I know the result will be like this, I will be unwilling to give up if I don’t give it up if I don’t give it up.

Moreover, this is how you do your studies. You must start with the simplest thing and don’t think about becoming fat in one bite.

After digging several layers in a row, I had to give up after confirming that this method would definitely not work.

Taking out the map, Chu Xingyun continued to explore the depths of the White Bone Cave, looking for traces of the rune formation.

Chu Xingyun no longer has hope for the soul bones. Unless he can study those rune arrays and imitate them, the soul bones really rely on luck.

However, if you want to study and analyze those rune arrays thoroughly, it is obviously not enough to rely on the collected current ones.

I walked along the way, but I don’t know how long it took, and finally... a cave hall appeared again in front of Chu Xingyun.

Looking at the hall with a diameter of 100 meters, Chu Xingyun felt danger again and frowned... Chu Xingyun carefully guarded and entered the Bone Hall.

Walking along the way, Chu Xingyun found in confusion that there was no such thing as the hall before, a large array of runes was carved on the ground of the hall.

Looking closely, the ground was very flat, full of solid soil, without any stripes or lines, not to mention the Dao pattern and array talisman.

Finally, Chu Xingyun arrived at the center of the hall, and in an instant... there was another loud noise on the surrounding ground. Skeleton warriors, holding bone knives, came out of the ground.

Needless to say, Chu Xingyun opened the Qingxuan body, and after slashing and slashing, a green central soul bone condensed again.

Frowning, Chu Xingyun felt a little puzzled. Could it be that... the condensation of this soul bone has nothing to do with the rune formation?

Unbelief of evil, Chu Xingyun started to search carefully in the hall.

But after searching the entire ground and walls, and even searching carefully at the top of the cave, Chu Xingyun did not see any array talismans or Taoist patterns. This...

If it were someone else, maybe at this time, they would choose to give up and continue on the road to hunt soul bones.

But Chu Xingyun didn't care about soul bones at all, because he knew very well that he could not hunt many soul bones by relying on his personal strength. Otherwise, how could the four emperors only have golden soul bones?

Therefore, Chu Xingyun placed all his hopes on this rune formation.

If there is really no rune array in this hall, Chu Xingyun's research direction must be changed. Therefore... if this hall is not studied clearly, he will never leave.

Since there is no ceiling, wall, or ground, the next thing to be detected is underground.

Looking at the ground of the cave hall with a diameter of 100 meters, this project is quite large, but fortunately, Chu Xingyun doesn't need to turn all the ground up, so there is no need.

At the location where the soul bones condensed, Chu Xingyun took out the shovel from the reincarnation space and quickly dug it out.

During the excavation process, finally... after digging more than a meter deep, the shovel shoveled onto an object as hard as a rock.

Carefully dig the surrounding soil, and soon... several green skeletons appeared in the soil pit.

Looking at the dense array talismans and lines on the green skeletons, Chu Xingyun suddenly lit up his eyes excitedly.

Carefully cleared the soil around the bones, and continued to dig, finally... an altar made of green bones with a diameter of ten meters and a whole body formed by green bones appeared in front of Chu Xingyun.

Looking carefully at the complex array talismans and Taoist patterns on the bones, Chu Xingyun quickly determined that this set of rune array was exactly the same as the one in the hall in front, but the area was reduced by ten times!

In the previous cave hall, the entire rune array, with a diameter of over a hundred meters, was directly carved on the ground.

However, this rune altar is different. It is only ten meters in diameter and one meter higher. The whole body is assembled from green and white bones.

In ecstasy, Chu Xingyun took out a white jade wine jar from the reincarnation space and put the rune altar into the white jade wine jar.

The white jade wine jar can hold ten jars of fine wine, so it is definitely more than enough to accommodate this altar.

Even the rune altar with a diameter of ten meters and a height of one meter is only laid on the bottom after being put into the wine jar. There is still 80% of the space inside the wine jar that is empty.

After carefully observing the rune altar in the Baiyu wine jar and confirming that there was no sign of collapse or disintegration, Chu Xingyun finally breathed a sigh of relief.

With anticipation, Chu Xingyun set out again and rushed towards the deeper part of the cave.

Not long after, a skeleton warrior, holding a bone knife, appeared in front of him.

clang clang! Crack clang clang clang clang clang clang clang clang clang clang clang clang clang clang clang clang clang clang clang clang clang clang clang clang clang clang clang clang clang clang clang clang clang clang clang clang clang clang clang clang clang clang clang clang clang clang clang clang clang clang clang clang clang clang clang clang clang clang clang cl

In the fierce battle, Chu Xingyun completely defeated the skeleton warrior in just three or two seconds.

Seeing that the skeleton warrior was completely defeated and the bones around him were scattered on the ground, Chu Xingyun couldn't help but observe the wine jar in his hand carefully.

Under Chu Xingyun's observation, a green air flow radiated from the skeleton warrior's body. After swaying in the air for a few times, it disappeared in the air.

Judging from the appearance alone, there seems to be no difference from before, but in fact, there are still subtle differences.

Chu Xingyun had the ability to remember everything he saw, so... he clearly remembered that before that, the green airflows swayed in the air for a few times, slowly dissipated rather than disappeared.

Dissipation has a process of gradually spreading and fading.

However, the diffusion is twice as low as the desalination process is very short.

If you were not interested and focused on observing, you would never find anything. After all,... it took less than one second to appear from the appearance of the green airflow to the final dissipation.

If you hadn't paid attention, who would have noticed the difference between that moment?
