After dealing with the Colored Grass Giant, this Colored Grassland will definitely be free of risks, which can be seen from Fang Yuan's unscrupulous strides forward.

After a while, Duan Fei and Fang Yuan came to the double shuttle tree, and at this time, without Fang Yuan's signal, Duan Fei consciously chose one and stood opposite to Fang Yuan.

After Fang Yuan nodded to Duan Fei, the two of them each stretched out their palms and pressed them into the palm prints on the double shuttle tree.

As the spiritual power gushed out, the double shuttle tree suddenly became dazzling, spreading the turquoise light to the surroundings, making the colorful grassland return to the most common turquoise color in a short moment.

At this time, the double shuttle tree is like incarnating as a king, and the colored grass around it has to bow down to it, making the breath of this area seem to be condensed into a whole.

At this time, I only heard a boom, and the ground between the two double shuttle trees collapsed and cracked, revealing a bottomless black hole!

From this cave, a black light gushed out, wrapped in an indescribable strange aura, which seemed to be able to pass between heaven and earth, transforming those incomparably gorgeous colors into the most basic black and white!

But this change in color occurred in the blink of an eye, and soon the heavens and the earth returned to their original brilliant colors, and the black light disappeared, and only the big black hole in the ground still existed.

Fang Yuan seemed to be blind to such a change, and instead made a gesture of invitation to Duan Fei, motioning for Duan Fei to enter this dark hole with him.

Not only can you not see anything in the cave, but there is even a prohibition to isolate the inside and outside, so you can't sense what is in the cave at all.

But Duan Feiyi was bold, how could he miss the opportunity at the moment? he also made a gesture of invitation to Fang Yuan.

So Duan Fei and Fang Yuan looked at each other and smiled, and the two of them jumped into the cave together.

When Duan Fei fell down, he had a feeling of being teleported out, and it was obvious that there was a cave in the cave, it should be an inner world in this secret realm at the moment, and it could become a space of its own.

I couldn't see anything in the darkness all around, I couldn't feel anything except the constant falling downward, it was as if I had fallen into a bottomless pit.

In the process of such a decline, it seemed that he couldn't feel the passage of time, but it seemed that after only a moment, Duan Fei had a down-to-earth feeling.

As Duan Fei's eyes widened and looked around, this should be in a huge underground space, and not far in front of him was a vast palace complex.

This underground space can definitely be said to be incredibly large, the high ceiling of the cave is almost no different from the sky, there are countless glowing crystals inlaid on the roof of the cave, as if turned into a sky full of stars, so that the underground space is not so dark that you can't see your fingers.

As for the ground, there are countless ravines and fissures that crisscross and crisscross, and the fiery underground magma flows through these ravines and fissures, and then under the reflection of the fire, this underground space feels like a part of hell.

But there is no doubt that the real and most important place at the moment is the continuous palace complex!

The style of this palace complex seems very quaint, but there is no movement except for the sound of lava flowing.

There is no doubt that this is also a place of dead silence, and like the colorful world outside, there is no living thing!

Moreover, although there is a lot of magma in the four places, it does not feel much heat, but it seems that there is a gust of wind blowing, which makes the four places very cold.

Even if such a place is regarded as a real hell, it can be said that there is no sense of disobedience.

But there was a flash of joy in Fang Yuan's eyes, and he couldn't help but say to Duan Fei: "Senior Brother Duan, our goal is right in front of us, but the next part of the road is the most difficult!"

Duan Fei arched his hand towards Fang Yuan and said, "Then Senior Brother Lao Fang will lead the way in front!"

Fang Yuan took the lead, and soon came to the gate of the palace.

The gate of the palace is a heavy and tall stone gate, the width of the stone gate is about ten zhang, and on each side of the gate is just printed with a palm.

After seeing such a scene, Duan Fei had nothing to say, he took the initiative to stretch out his hands towards Fang Yuan, and then walked to the side of the stone gate.

Now it is certain that in this mysterious secret realm, whether it is a level or a prohibition, it is all related to the pair, and it is no wonder that Fang Yuan is bent on finding Duan Fei to cooperate.

At this time, Fang Yuan was also standing on the other side of the stone gate, and after nodding to Duan Fei, he reached out with Duan Fei and pressed the palm prints on both sides of the stone gate.

As the spiritual power of the two of them surged, the stone door slowly opened, and suddenly a cool aura gushed out from the inside out, fortunately, Duan Fei and Fang Yuan were not ordinary people, and they didn't feel that this chill was unbearable.

Soon, the stone gate was completely opened, and Duan Fei and Fang Yuan stepped forward at the same time, entering the stone gate.

Behind the door is an extremely empty hall, the dome is in the shape of a semicircle, and there is no support in the whole hall, which alone is enough to show that the construction level of this palace is quite high.

The hall was extremely silent and cold at the same time, as if you were in an ice cellar, and in the center of the main hall stood two stone platforms that looked like altars.

The stone platform is not high, at most there is only about one person, and there is a stone pillar-shaped thing erected on the stone platform, and I don't know what it is used for.

Duan Fei turned his puzzled gaze to Fang Yuan: since Fang Yuan was an old man here, he should naturally know what was going on right now, right?

Fortunately, Fang Yuan did not sell Guanzi, but directly explained to Duan Fei that at present, this hall is completely closed, and if you want to open the mechanism and go out, you need to activate the mechanism on the stone platform.

As for the mechanism on the stone platform, it is necessary to forcibly press the stone pillars on the two stone platforms at the same time to the level of the stone platform, and then the back door of the main hall can be opened under heavy pressure.

This method of opening the mechanism is simple to say, but when you really want to press down on the stone pillar on the stone platform, the more you go down, the greater the force of the rebound, and it is not easy to completely press down the stone pillar.

Fortunately, the competition in this level is brute force, even if it doesn't succeed, there is no consequence, at most, it is to rest for a while, and wait until the strength is restored to try again.
