At this point, Luo Yi couldn't care so much anymore, he rounded his arms, adjusted the spiritual power in his body to the limit, and raised his sword to slash wildly at the huge sealing stone in front of him!

'Bell ......'

When the 'Moyun Sword' is slashed, the streamer is dazzling, and the sparks are splashing! The loud sound of metal colliding is deafening! The sound echoed in the claustrophobic space, like a brass bell, and the sound hit people's hearts. Under the burst of energy, the mountain cave shook even more, and it was about to collapse in an instant!

In the blink of an eye, Luo Yi had already slashed dozens of times, making his hands slightly numb and sweating on his forehead. At this time, the sealing stone in front of him shook violently with the cave wall, and finally a lot of cracks appeared, Luo Yi didn't have time to rejoice, and still cut it unremittingly.

At this moment, the violent air pressure fluctuations behind them could be sensed by their skin alone, and the sound of breaking the air like a cannonball was extremely sharp.

"It's too late!"

The three of them had already seen the huge figure of the 'Ethereal Demon' out of the corner of their eyes, with angry flames in their eyes, slamming their fists like meteors, smashing them head-on! It's coming so fast!

Luo Yi's heart was pounding, the powerful sense of oppression was suffocating, and the strongest sense of fear in his life lingered in his heart. But under the huge pressure, the potential was infinitely stimulated, and Luo Yi's body was full of golden light, like a god, crystal clear and clear!

With instinct, Luo Yi snapped his fingers lightly, the light flickered, and the second daughter disappeared from the spot in an instant! Then, the giant fist of the 'Ethereal Demon' arrived, and that punch smashed into the road-sealing boulder like a heavy machine like no other in the world.

'Boom!! ’

Loud bang! The shockwave airflow poured into the cave with crazy smoke and dirt debris, and the road-sealing boulder shattered into fine slag in an instant, and rushed straight out of the cave with the violent air current! I saw that the giant trees outside the cave fell and burst into countless pieces, frightened countless birds and beasts, and suffered countless people, so that this ethereal night, which was not peaceful, instantly seemed to fall into the battlefield of annihilation, and the air was filled with gunsmoke and blood, and even if the heavy rain washed away, it could not wash away the deep fear.

At this time, the cave was turbid, a strong light flashed, Luo Yi and the second daughter flashed into the depths of the cave in reverse, and the eyes were chaotic, the bridge that stood earlier was collapsing, and countless rubbles kept falling into the bottomless abyss that was bubbling with cold air, and the sound of 'emptiness' was terrifying, and they didn't care about what happened behind them, Yan Ji picked up Nangong Liyue, side by side with Luo Yi, and frantically fled towards the cave.

After the loud bang, the noisy sound continued, and the 'ethereal demon' turned to look into the depths of his lair, and began to rise from his body, and the black gas kept jumping like firelight, and the smoke and dust around him rolled and avoided. This old demon has been completely enraged, and the anger in his eyes seems to tear this heaven and earth apart, and in the next second, the air flows rapidly, and the 'ethereal demon' disappears in place!

At full speed, Luo Yi and Yan Ji's travel speed can be described as galloping, but this 'ethereal demon' lair is extremely deep and complex, like a huge underground palace, they panicked in the huge labyrinthine corridor, and flew around.

At this time, if they can calm down and take a good look around, they can find that the description of this underground palace is very appropriate, only to see that the walls on both sides of the corridor are flat and smooth, and there are all kinds of lifelike monster sculptures standing beside them; The corridor connected many halls of different sizes, but they didn't have the heart to study what these halls were for, they only felt that every other distance, there was a lot of light shining from the doorway, like a street lamp, quickly passing away from the back of their heads.

I don't know if this underground palace was built by this 'ethereal demon', or if it was just robbed by it, but I can only know that this builder can be described as a genius, and every palace passage is very exquisite, if the living are not familiar with the layout of the doorway inside, it is very likely that they will get lost in it and be caught by its owner in an urn.

At this moment, Luo Yi and the three of them were lost in it, they soon found that every place here was so familiar, they seemed to be circulating in a space, in order to determine this idea, Luo Yi decided to draw a mark, so he struggled to leave a deep sword mark on the wall, he could be sure that this was the only one in the entire cave palace, and then held the sword behind his back, and flew forward with the second daughter quickly.

As expected, it didn't take long for them to find the only sword mark left by Luo Yi on the wall not far in front of them. The three of them frowned, and did not want to linger longer, turned around and ran into a nearby hall, and when they passed through the doorway, they did not forget to knock a missing corner on the wall of the doorway.

A similar mark was left on the wall when exiting the opposite doorway. When they walked out of the front hall, they found that there was a long corridor running through them, and on the other side was a very similar room, exactly what they had seen before they entered.

At this time, they looked further, but found that they could see more, and in front of them they could see more corridors crossing the same halls, and they turned to look behind them, and the same was true. It is as if they are standing in front of an infinitely looping glass lens, with an infinite replica of the current standing position in front and behind. Fortunately, they were relieved that there was no mark on the door opening of the opposite temple.

So it can be determined that this is not an illusory mirror, but just a very ingenious architectural layout, at this time they decided to try to cross each temple, and if it goes in one direction, maybe there will be a turnaround, if the corridor can be understood as a circular passage, then if the palace is understood through the architectural structure, there can be no geographical circulation, unless the whole palace is a sphere.

Thinking of this, in order to better remember each place, they deliberately slowed down a little, constantly looking left and right to try to remember every room they had walked in, but everything was so similar that it was difficult to distinguish each room.

Something terrible happened, and soon after, they clearly saw that there was a very obvious knock mark on the door of a temple not far ahead, and they were back to square one!

This situation made Luo Yi's scalp tingle, and he couldn't believe it, "This is impossible?" Are we really running back and forth on a sphere? Luo Yi was facing the oppression of a terrible threat at this time, coupled with the labyrinth that he could never get rid of, he was a little psychologically broken, and an anxious heart fire was burning in his body. At this time, a gust of wind blew, and I felt a chill on my body, only to find that my clothes had been soaked with sweat.

Faced with such a situation, Yan Ji suggested that he stop for a while, no matter how much running in front of him was in vain, it was better to save some effort and think about how to face it.

"What do you think?" The three of them stood on the edge of a doorway, Luo Yi looked at the sword marks left on the wall before, and asked Yan Ji beside him.

When Yan Ji heard this, she lowered her head and thought for a while, and then said, "I think it's very likely to be a demonic barrier!" ”

"Barrier ......?" Luo Yi repeated it and said he couldn't understand it.

"The magic barrier is a delusion in your and my hearts, the more we want to escape, the more complicated the structure here becomes, we can't get rid of the obsession in our hearts, we will never be able to break through the magic barrier in front of us, or we will be trapped in this place forever!"

"It's so dark and cold, I don't want to be stuck here forever! I want to go home......! After hearing this, Nangong Liyue once again had tears in her eyes, and said with a sad cry in her mouth.

"This ...... How do you say? Luo Yi also felt that one head and two big, and the heart that was not calm at the moment was like the sand that was poured into the drum, becoming a mess, and finally being harmonized into a thin mud.

"Little Liyue, don't panic, the more chaotic our hearts are, the more complicated everything in front of us will become, in my opinion, we might as well calm down, maybe there will be a turnaround!"

"Yan Ji's words are reasonable, but that 'ethereal demon' may appear at any time, and there is a burden in my heart, and it is not easy to be completely calm." Luo Yi took a deep breath and exhaled heavily, then looked at Yan Ji and Nangong Liyue and said.

Then Yan Ji pulled Luo Yi and Nangong Liyue to sit on the ground, and said with a smile: "No matter, today is life or death, everything is left to fate, anyway, if it weren't for you, the master, Yan Ji would have been a lonely ghost a long time ago, how can she be frightened here now." ”

"Yan Ji, you are serious......" Luo Yi saw that she was calm and free, and felt a little ashamed in his heart, and was affected by her emotions, and his mood was not so messy, so he said with a smile.

"The so-called demonic obstacle is just an obsession in our hearts, we have too many things in our hearts to worry about, and we can't let go easily, so we are all trapped in the cage of our hearts, and we can't escape until we die."
