As soon as ye CuO's voice fell, Du Lin, Fang Zhuowen and Xiao Mu immediately protected Ye CuO in the middle, and then they went into the cave together.

There may be something in the deep of the cave that can shine. The light from the deep of the cave reaches the entrance of the cave, but it is very dim. If ordinary people can't even see the situation at their feet clearly, but with their cultivation, they can see the situation two or three meters ahead.

Moreover, even their mind can't go deep into the cave. They can only detect the situation about 10 meters ahead. If they go deeper, their mind will be smashed by the power inside. Once their mind is smashed, their soul will also be injured.

As soon as the four entered the cave, the light shield on their bodies or the flashing light of their swords and swords lit up the surroundings.

They can all see that the stone walls of the cave are black, reflecting the dark luster of metal. Besides these black stones, there is no sign of life activity.

"After the strength inside weakened, there was no danger in the area ten meters from the entrance of the cave."

As he walked, Du Lin looked at the black stone wall and asked, "elder ye, what are these black stones made of? They are so hard that they can't be broken even the top-grade magic weapon, or even the Zhenyang sword?"

Ye CuO said with a smile: "I really don't know what the material of these black stones is. But in those years, lingkongzi tried to split these stones with Zhenyang sword, but the result was that he didn't even split any debris.

If it wasn't for the weakening of the strength, now the same terrible force is raging here, but these stones are still intact, so we can judge how hard they are. "

Fang Zhuowen said: "elder Ye is right. Under such terrible power, he can still keep in good condition. The hardness must be amazing..."

Ye CuO said: "if you want to see if these black stones are really so hard, elder Du will have a try."

Du Lin worried: "elder ye, if you attack these black stones, will it cause bad changes?"

"No!"

Ye CuO said: "I don't know how many times I tried the lingkongzi in those years. You can split it at ease!"

After getting Ye CuO's confirmation, Du Lin didn't hesitate and immediately mobilized his strength. Then he split a sword awn with Zhenyang sword. The sword awn split on the black stone wall and didn't even leave a white mark.

"These black stones are really very hard!"

"But it's really a pity that these black stones are so hard that if they can be used to refine utensils, they will certainly be very powerful!" said Turin

Then, as they walked and talked, they walked into the cave. However, because of the powerful fluctuations inside, they did not dare to relax their vigilance, and their speed was very slow.

Although the speed was not fast, the distance of ten meters was soon over. At this time, they came to a corner, then turned and walked less than two meters. There was a transparent membrane wall in front of them, blocking their way.

Through this layer of transparent membrane wall, ye CuO can see the situation inside, which is an estimated tens of thousands of square meters of wide space.

Xiao Mu said in a low voice: "there is really a wide space here!"

Fang Zhuowen also said: "this space seems to be isolated from the outside. I don't know how it was formed..."

Ye CuO said: "when lingkongzi was swept into the space by the space vortex, he almost died in it. He was lucky and just escaped. Otherwise, Linglan world would not have any trace of him!"

"Elder Ye is right. When lingkongzi came here, he was only in the golden elixir period. If it wasn't for bad luck, he would have died in it..."

Speaking at the same time, their eyes have long penetrated the transparent membrane wall, the situation in this space into the eye.

Almost every part of the space is like a sharp blade of cyan light. The cyan light blades are big and small, the big ones are even more than ten meters long, and the smallest ones are about two meters long.

The green light blade is dense, almost no gap. It splits wildly in the black stone wall, but it can't leave a trace on the black stone.

Although they didn't see the blue light blade leaving traces on the black stone wall, they didn't dare to despise the power of the blue light blade.

Even though there was a layer of transparent membrane wall, the cyan light blade inside didn't split from the transparent membrane wall, but the four people could still feel the terrible power of those cyan light blades inside.

There was a look of shock on durin's faces. Now that their power has weakened, the power of the cyan light blade is still very powerful. If they are struck by those terrible cyan light blades, they are not sure that they can resist.

Fang Zhuowen's face was both shocked and worried: "those cyan light blades are too powerful, and they are almost everywhere. Once we go in, we can't completely avoid those cyan light blades!"

Du Lin Qingxing said: "fortunately, the power of cyan light blade has weakened a lot. If we had come in before, it would have been the result of death and no life!"

When the three of them were shocked by the power of the green light blade, ye CuO's eyes had already seen the innermost part of the wide space, where there was a space crack that was more than ten meters long and nearly one meter wide.

In the message given to him by the ghost of snow-white tail, although the length of the space crack was not as long as it is now, the difference was not big, and the shape did not change much, so the space crack was relatively stable.

After discovering that the cracks in the space have not changed much, his previous worry about some new changes here is finally put down.

Since there is no bad change, then he can enter the space according to the method used by lingkongzi at that time, and avoid the terrible attack of cyan light blade with the law summarized after lingkongzi research.

Although the transparent membrane wall couldn't stop them at this time, he still didn't rush in. After all, he just came here. He still needs to observe for a while to make sure the situation inside. For example, in those years, the method of the spirit hole is still applicable, and then he will enter.

Among the cracks in the space, green light blades of different sizes fly out continuously, chopping through the inner space.

On the black stone wall next to the space crack, ye CuO saw crystals about half a foot long, flashing dim starlight, which was his target this time.
