Zhang Linchen took a deep breath, thoughts flew in his mind, he lowered his head and thought for a moment, then looked up and said, "How about we walk backwards?"

Wang Duan pondered for a moment and said, "You can try." ”

The two began to gallop back, and after some time, they saw a towering mountain peak standing in the distance.

"I remember that there are no such high mountains in that place, right?" Zhang Linchen touched his chin.

Wang Duan was also confused, and said to himself: "Could it be that Poor Dao guessed wrong, in fact, it is not an independent space, but a ...... An artificial barrier!"

At the end of his life, his eyes grew brighter and brighter, and he immediately said, "Let's try again and see what this is!"

The two of them were much more careful this time, setting up many marks along the way, and they also found the marks left by other lives, but it may be too long, many of them have blurred or even dissipated, and it is difficult to detect them if you don't pay close attention.

When their figures crossed the "barrier" again, they immediately walked back, and then saw the mountain peaks they were familiar with.

"It's probably artificial!" Wang Duan's tone was quite affirmative.

"Maybe this is the end of the world. Zhang Linchen sighed.

Wang Duan pondered for a moment, shook his head, and said, "Then why do you want to set up barriers? ”

"Why don't we observe it again?" Zhang Linchen proposed.

That's exactly what I mean. ”

While observing possible clues, the two searched for the marks left by the ancients, hoping to find answers from these clues.

Soon, they determined the boundaries of the barrier, and at a great distance on both sides, they found that someone had left a handwriting, succinctly stating that this was the barrier of heaven and earth, which could not be crossed.

Later, ancient texts were discovered one after another, some of which were either erased, leaving a little trace, or too vague to be recognizable, or they were in awe of the barrier, persuading those who came after to stop and turn back.

"I didn't find anything useful, so it seems like I have to turn back. Zhang Linchen sighed.

"I can't go back so easily, I finally came here, I must check it out. Wang Duan insisted.

In fact, he wants to get more natural treasures, in this trial, it really cost him a lot of treasures, and now he only gets some discarded materials, but he is determined to hollow out this place, how can he turn back so cheaply?

They followed the barrier and began to explore in both directions, and when they really thought that there was no solution to this place, an abyss appeared before them through the invisible barrier. The abyss is very dark, you can't see the end, it is full of unknowns, and there is a faint atmosphere of chaos.

"Do you want to go down?" Zhang Linchen looked down at the darkness under his feet, this abyss was not as big as they saw at the beginning, it was many times smaller, and it seemed that it had been split out of the situation.

"How can you be willing if you don't break through?" Wang Duan had a hint of relief on his face, and he didn't know when a whisk of dust appeared in his hand, and the surface was shiny, which was very extraordinary.

Seeing this, Zhang Linchen glared and said, "Didn't you say that your family is gone?"

Wang Duan smiled and said: "Didn't you just know each other at that time, you are not familiar with it, leave a hole card a little, and now Poor Dao and you are brothers who die with the same voice and are like siblings, so naturally you have to be honest with each other." ”

Zhang Linchen glanced at him and said, "Whoever is close to you is like a brother and sister, let's talk about it first through this invisible barrier!"

Wang Duan smiled and said, "Daoyou has decided?"

"Of course, but be very careful, I don't want to explain it here. ”

After a while, Wang Duan took Zhang Linchen and flew directly into the abyss and rushed to this dark place.

The two of them gradually felt a huge pressure coming towards them like a tidal wave, and the atmosphere of chaos around them was unpredictable.

Soon, they came to the bottom, where they couldn't see their fingers, it was extremely dark, very depressing, and the chaotic aura was even more serious.

Zhang Linchen's body was unwell, as if a big hand was about to tear him apart, he couldn't help but use his spiritual power, and a glowing light appeared on the surface of his body to resist the erosion of the aura from the outside world, and he also secretly held a rune stone in his hand.

"There are some remnants of the past here, which should not be underestimated, pay attention to follow the poor road. ”

Wang Duan also glowed, and took out a bronze lamp with his other hand, and then a beam of flame illuminated the surrounding darkness, and the chaotic aura also weakened a lot under the light of the candlelight, Zhang Linchen felt a sense of relief at the same time, and glanced at Wang Duan.

Leaning against the smooth walls, they cautiously walked in the direction of the invisible barrier, with a number of fallen bones of all races along the way. Some died together because of the fierce battle, while others died inexplicably, which is quite strange. For example, there is a humanoid purple corpse, kneeling on the ground and looking up at the sky, and a humanoid white bone sticking to the wall, with teeth and claws on its limbs, and a human skeleton standing motionless, as if waiting for something......

"Is it really so dangerous here?" Zhang Linchen frowned, "Why haven't we encountered it yet?"

"You see the traces of these bones, they are all very old, and this abyss has existed for more time than we can imagine, even if there was a lot of danger at the beginning, it has been erased by the years. Wang Qian guessed.

Due to the slowdown, the two of them walked for a long time, and gradually a plant appeared around them, which was a grass with a strange smell, growing in the cracks of the wall.

The two of them stayed away for a while before stopping to observe, no one knew this grass, and even Zhang Linchen, who was full of books, felt very unfamiliar.

Wang tried to collect it, but was stopped by Zhang Linchen, this grass contained a chaotic aura, similar to the residual power here, and it could be dangerous if it moved.

"We don't know this grass, and it would be bad if there was danger, and the bones were the best proof of that. Zhang Linchen said seriously.

"Poor Dao just wants to take a closer look, since Daoist friends said so, then leave it alone, and keep walking. Wang Duan smiled smugly.

Later, they found some moss and water stains, a surprise to the two of them, and combined with the grass from before, they believed that they might have been behind the barrier, otherwise they couldn't explain the appearance of these things.

In the previous period, the two of them did not find any vegetation or even water sources in that vast and boundless world, even the riverbed was extremely dry, and the whole world seemed to be composed of sand and solid stones, bare and lifeless.

And now that water and grass have been discovered, this may not be the lifeless world it used to be.

Wang Duan put away the ancient lamp, grabbed Zhang Linchen with an excited face and flew up, and the light above became bigger and bigger, until he left the abyss.

At first glance, the two of them saw the greenery all over the ground, all of which were half-human-high grass, and there were ancient trees and mountains far away, and there was a dazzling sun in the sky.

The environment has changed drastically, compared to before, it is simply a day and a place, this is the normal world, the one outside the barrier is too dilapidated and full of weirdness.

Zhang Linchen stood on the verdant grass and took a deep breath, not only is the air fresh here, but even the spiritual power is much richer, it is like a paradise.

"Do you say there is life here?" asked Zhang Linchen.

Wang stood in the air, kept observing the four directions, and said, "Very likely, we must be careful. ”

The next moment, his eyes lit up, and he said, "Fellow Daoist wait here, and the poor Dao will come when he goes." ”

After a while, Wang Duan returned, and immediately pulled Zhang Linchen to the end of the abyss, where there was a path on the ground, as if it had been stepped on by someone, and there were flowers and plants on both sides.

"It's certainly not easy for those who step out of this path. Wang Duan stroked the ground, looked intoxicated, and said: "Poor Dao can feel the existence of Dao patterns, I don't know how long it has been, and there is still a little left. ”

Zhang Linchen looked at him, quite speechless, and said, "Do you want to have an enlightenment and feel the Taoism of the sages?"

Wang Duan laughed, waved his hand and said: "It's free, the Dao pattern is already very blurred, and the Dao rhyme is almost dissipating, it's useless, let's go along this road." ”

The two continued to walk, and the appearance of this trail reminded Zhang Linchen of the long trail in Lingxiao Temple, and both seemed to have the same effect.

The mountains and rivers are fragrant, the flowers and plants are fragrant, the ancient trees are standing, and the warm sun is mild.

After a long walk, the two of them walked through the mountains and mountains, and the trail never stopped, and they were both curious about where it led. However, there was one discovery that caused the two to speculate, and they had never seen a single creature until now, not even a crawler. However, unlike that dead world, it is full of life, green grass, flowers, beautiful and fragrant.

During this period, Wang Duan flew out in a hurry, trying to find the treasures of heaven and earth, but there was nothing, just ordinary flowers and plants. Zhang Linchen said that after walking this trail, it is not too late to look for it.

Later, on a relatively smooth mountain wall, four big characters appeared, and both of them knew each other: the sky is difficult to overcome.

The pen walks the dragon and snake, in one go, the meaning is far-reaching, eternal, and there is no other special place. Compared with the "all false" I saw before, the styles of the two are very different, and they are obviously not from the hand of one person.

But in the center of the four characters in front of him, there was an obvious crack, obviously a creature did it on purpose, and there was a trace of anger.

"It seems that these two have been on the right side and have had a cross-time and space fight. Wang Duan sighed twice and said: "These words have obviously existed for a long time, the vicissitudes of life are ancient, and although the crack has a trace of time, after all, the time span is too long, and the two sides have been separated by eternity. ”

Zhang Linchen sighed: "There are too many secrets hidden here, I really want to know the truth of everything." ”

Wang Jin shook his head with a smile, his tone was a little sour, and said, "Everything here is not something that we can touch, as for the truth of everything...... Hehe...... When you are invincible, you may know. ”

The two walked slowly, passing by a stream, and Wang Duan suggested going down to take a bath, after all, the road was dusty and contaminated with too much dust.

Zhang Linchen looked at himself in the water, he was in a trance for a while, faded away from childishness, his appearance became a lot more mature, a little taller, his face was a little resolute, his eyes were bright and shining, full of confidence.

He only washed his face, but Wang Duan jumped into the water with a "plop", splashing a large splash, he stood in the waist-length water, and tried to see if there were any fish, but found nothing.

When the king had reached the shore, the two of them continued along the path until they came to an endless grassland, where the green grass was not as high as ankles, soft and comfortable. The two walked and walked, and when they reached the deepest point, the trail finally came to an end.
