On the cliff wall about ten meters above the ground, a touch of green greeted Mu Yu's eyes.

It was a living vine.

The living vine, which was only an inch long, appeared there very abruptly, and the rest of its body seemed to disappear out of thin air. Mu Yu crossed the critical line and looked in the direction of the living vine, and there was no longer a living vine in sight.

This strange phenomenon made Mu Yu think of a possibility at once!

"What's the way to talk about it quickly!" Old Tan cheered up again.

"Do you see the live vine? The live vine can only be seen on one side, not on the other side. What does this mean?" Mu Yu said excitedly.

"What does it mean?" Old Tan's brain was not as bright as Mu Yu's, and he couldn't react for a while.

Mu Yu laughed: "This shows that although the length of this formation spans the entire valley, it is only ten meters high. You see the live vine, there is only one section, that is to say, most of its vine body is on the other side, but we can't see the other side, so there is only one explanation, if the critical line is a wall, then the live vine is over the wall, we can't see the live vine from the other side of the critical line, because the live vine is not on the other side of the critical line. ”

"I'm dizzy by you, didn't you say it came over the wall, how can you say it's not on the other side?" Old Tan was more and more confused by Mu Yu's tongue twister-like explanation.

Mu Yu drew a rectangular box on the ground and continued to explain: "To put it in layman's terms, we are now equivalent to a square wooden box. The two sides of the longer box are equivalent to the two cliffs of the valley, and the shorter sides are the boundaries of the mirror array. The boundary is set up in a powerful formation, and no matter which boundary you walk from, you can only go around in a circle in the box. If you want to get out of this box, you can't walk around inside the box, you have to climb out of this box!"

He pointed to the live vine on the cliff and continued: "This live vine should grow outside the box, but it accidentally went out of the wall and extended into the box, which made me think of a way out." ”

Lao Tan thought about it for a long time and finally understood, he patted Mu Yu's shoulder and said appreciatively: "You really impress me, you can actually think of this!"

No formation is perfect, and the arranger certainly didn't expect that a piece of living vine would become a flaw in this formation. The arranger has tried his best to arrange the critical line of this formation perfectly, as long as he can't find the critical line, it is impossible to get out of this formation, and even if he finds this critical line, there is no way to destroy the formation pattern.

This formation is only ten meters high, and people who enter here can't fly, they don't know how high this formation is, so it is more than enough to trap cultivators below the out-of-body period, and they won't even think that they can climb out when they die. But this formation was sold by a live vine in this way, and Mu Yu knew the way to escape.

In fact, Mu Yu thinks it's a coincidence, but the intention of the arranger is not to trap people, he is intent on testing the people who come in to break the formation, and this live vine is a hint that the arranger deliberately put there, otherwise even if Mu Yu looks for it, he won't be able to think of climbing out for a while.

"So we have to climb ten meters high?" Old Tan frowned, there is an inexplicable pressure in this valley, it is just that if you can't fly, if you climb too high, you will be greatly oppressed, you can't climb very high at all, the cave they live in is not as high as ten meters.

"Can you climb ten meters?" asked Mu Yu. If Lao Tan can't stand this pressure, then he doesn't have a role, Lao Tan said that the situation here, if you can't climb ten meters, you can only stare at the treasures at your fingertips.

"I can't reluctantly, but I'm worried that you can't. "Lao Tan told the truth, after all, he is in the Yuan infant stage, both in terms of physical fitness and cultivation is higher than Mu Yu, Lao Tan is definitely not a problem to climb out, and Mu Yu is a little difficult. This method was thought of by Mu Yu, and Lao Tan couldn't bear to leave Mu Yu alone.

This is a huge challenge for Mu Yu, Lao Tan can only barely climb up, and Mu Yu's hope is very slim. But since he has found a way to get out, Mu Yu will try it anyway, even if he can't climb up for a while, Lao Tan can help him.

"By the way, uncle, where are you going to climb from, do you want to continue deeper into the valley or climb out from the direction of the valley?" asked Mu Yu. If you find a way out, then you have two options, continue to go deeper and find the Heavenly Demon Fruit, or go back the same way and leave the Valley of the Dead Wood through the poisonous mist.

Lao Tan was stunned for a moment, he hadn't thought about this problem, being trapped here for half a year made his thinking a little dull, which was a difficult choice for him. After all, he used to come in to find the Heavenly Demon Fruit to find Dead Wood Changqing to avenge him, but he was trapped for more than half a year. It had calmed him down a lot for most of the year, and he was wondering if it was worth it for him to come in the first place.

"I'd better get out!"

Lao Tan thought about it for a long time and figured it out, this maze is not much dangerous, but it has trapped him for more than half a year, and he doesn't know what he will encounter in the future, if he encounters a more difficult test, he may not be able to get out for the rest of his life. He was looking for Deadwood Changqing to do something, but if he continued to be trapped inside, it would be more than worth the loss.

Mu Yu understands Lao Tan's choice, people are best only alive. He didn't plan to go deeper, he didn't have any wishes as real as his own life, and besides, he didn't have any wishes, just got up on a whim to find food. He always thought that it was an outrageous choice for him to come in, in the eyes of outsiders, this was simply a child's play with danger, if Mu Yu knew that it was so dangerous inside, he would not have come in to join in the fun.

"Which way is the way out?" asked Old Tan.

Mu Yu looked at the direction he came from, confirmed the mark, and said, "According to the direction I remembered, if you climb from the side where you see the live vine, you should continue to go deep into the valley, and if you climb from the side where you can't see the live vine, you will return the same way." All we have to do is climb to the height of a living vine, then move sideways and jump off. ”

If Mu Yu's idea is correct, when Lao Tan climbs up and jumps down, he shouldn't be able to see Lao Tan below.

However, both of them were seriously injured at the moment, and Mu Yu's arm was still aching, and it was impossible to climb out directly. Lao Tan is also exhausted and needs some time to recuperate. As far as Lao Tan is concerned, he has been trapped here for more than half a year, and it is not bad for the past few days.

"Let's heal our wounds first! That damn big-eyed monster nearly squirted me to death that day. Mu Yu complained that the demon beast in the water would breathe fire, and he was not afraid to choke it on dumb fire!

They took a pleasant bath by the river, and the smell of last night's fight filled the two of them with a fishy smell, although it was strange here, but fortunately the dead wood did not poison the river water, but did not let people cross the river.

They went back to the cave, and now that they knew how to get out, they didn't have to hurry, they just had to wait until they were fully recovered before climbing the wall. Mu Yu can finally sleep beautifully at night, and what is there to worry about after solving the current matter?

The night was shrouded again, Mu Yu was already asleep, and Lao Tan sat there looking at the darkness outside the cave in a daze. After being trapped here for more than half a year, he suddenly found that he could get out alive, and this feeling of excitement kept him awake. Thinking of his deep hatred, he understood that the possibility of making Deadwood Evergreen make a move by looking for the Heavenly Demon Fruit was too low, and he had to rely on himself to take revenge.

However, at this moment, a dark shadow suddenly appeared on the bank of the river below the cave, without any foresight, like a ghost, and if you did not look closely, you would not be able to find any trace of him. There were originally many lazy demon beasts gathered on the riverbank, but as soon as this black shadow appeared, all the demon beasts immediately fled in terror. The demon beasts in the darkness seemed to be very afraid of this person and did not dare to approach. The black shadow looked up at the entrance of the cave, and suddenly flew up, approaching the cave.

He can actually fly!

Lao Tan suddenly found that the roars of the demon beasts around him seemed to disappear, which made him feel a little puzzled, he leaned out and looked down, but at this moment, the black shadow suddenly floated into the cave and landed behind Lao Tan.

The speed of this black shadow was so fast, Lao Tan only saw that he was shaking in front of his eyes, and then he smelled a strange fragrance, this strange fragrance was just absorbed by him a little, and suddenly his brain became groggy, he only felt that the world was spinning in front of him, and then he fell to the ground unconsciously.

The black shadow didn't look at Lao Tan at all, but walked towards Mu Yu, who was sleeping in the cave. Mu Yu and Xiao Shuai were snoring slightly, unaware that there was an uninvited guest in the cave. With a slight wave of the black shadow's hand, the sleeping wooden feather seemed to be held up by an invisible hand, and then the black shadow was taken out of the cave.

The black shadow flew to the critical line of the maze with Mu Yu, and then put Mu Yu on the ground. He glanced at the critical line, and his fingers formed several complex handprints, and the critical line slowly turned into a solid wall!

This black shadow is not restricted here, knows where the exit is, can also control the critical line, and can fly, which completely shows the identity of this person, it must be the legendary dead wood evergreen.

Deadwood Changqing laid down this formation, secretly observed those who entered the formation, and also witnessed the whole process of Mu Yu breaking the formation, and then heard that Mu Yu wanted to return the same way, and felt very unhappy in his heart. Finally, a person who could crack his formation appeared, but this kid had to retreat, how could he let Mu Yu leave so easily?

Deadwood Changqing helped Mu Yu so that Mu Yu didn't have to climb the wall, but at the cost of going deeper into the valley. And the way in was blocked by the dead wood evergreen, so Mu Yu had no choice at all, so he could only go deep obediently.

Deadwood Changqing glanced at Mu Yu, his figure in the darkness was particularly gloomy, and he couldn't see his appearance clearly. Then there was a strange sneer in the darkness, and then the shadow began to shake in place, gradually merging with the surrounding darkness, and disappearing without a trace in an instant.

Our Mu Yu didn't know all this, he slept soundly, and turned over, scratched his thighs, grinded his teeth, and muttered a few words by the way. Xiao Shuai also slept like a dead pig, and from time to time he smacked his mouth, as if he had dreamed of some delicious chicken legs. It curled up on Mu Yu's shoulder, and the dead wood evergreen smoothed Xiao Shuai over.

They don't even know they've been kidnapped.
