It was pitch black outside, but there was a bright light not far away, as if someone had lit a fire. According to the distance of the bright light, the man must have been on the other side of the riverbank, and from time to time there were a few faint shouts. Then there was a green light flashing around, it was the flickering light of that person's magic weapon, and he seemed to be inseparable from someone.

"That man must have come in with you, shouldn't he have lit a fire, for at night all the monsters in the river will climb up, and he will be besieged." Lao Tan said lightly, the people on the other side didn't know that there would be demon beasts in the valley at night, and his little fire was equivalent to completely exposing his position in front of all the demon beasts.

Mu Yu didn't know what the so-called demon beast was, but he was glad that he had met Lao Tan, otherwise he would probably have fought the demon beast below tonight. That person is in the Yuan Infant Stage and can insist, and he is only in the Jindan stage of cultivation, where can he last so long.

"Can we help him?" Although that person has a very bad attitude towards Mu Yu, if they can stay together in this ghost place, they have a better chance of surviving.

"Help, how to help, if he is smart, the fire will be extinguished, otherwise more and more demon beasts will be attracted to it, and then he will definitely die." Old Tan shook his head and retreated back into his cave. At such a long distance, you can't fly, you can't see the situation clearly, and no one knows when the time comes.

Mu Yu thinks about it, and now he is a real person watching the fire from the other side. If the fire is still there, the man will not be able to escape the danger.

Fortunately, after a while, the man seemed to realize the problem, and the light of the fire on the other side disappeared all of a sudden, leaving only the light of the magic weapon, and after a while, the light of the magic weapon also disappeared. I don't know if the person deliberately didn't shine or was buried in the mouth of the demon beast, the surrounding was quiet again, Mu Yu sat back in the cave, for today's plan is to rest first, and then plan tomorrow.

Mu Yu slept very badly this night, he tossed and turned for a long time before falling asleep in a daze, and then had an inexplicable dream, he dreamed that he was trapped in this ghost place for the rest of his life, and finally couldn't stand the loneliness and wanted to commit suicide. Then he saw Feng Haochen coming to stop him, he didn't have time to be happy, the people from the Mie Palace came, Feng Haochen was captured by them, Mu Yu reached out to save him, and then his hand touched the cave wall and woke him up.

He turned around and went back to sleep, and when he woke up the next day, he didn't remember the dream at all.

The sky was bright, and there was still a heavy fog around, and Lao Tan woke Mu Yu up and told him that it was almost noon. Mu Yu looked outside, thinking it was early morning. They stayed in the hole and couldn't stretch their hands or feet, so they climbed down. On the bank of the river, Mu Yu opened his eyes wide to see the situation on the other side, but unfortunately the visibility was too low, and his vision was severely suppressed.

Mu Yu went to the river to wash his face, the river water was cold, which made him sober up a little. He wanted to try again, but Lao Tan told him that it was in vain, but Mu Yu was not reconciled, he ran forward this time, needless to say that he came back in a circle.

"I've tried it many times, and this maze is so powerful that I can't take it at all. Lao Tan said calmly, he used to be unwilling, and finally became disheartened after walking dozens of times, and now he has become accustomed to it, he knows that if he wants Mu Yu to accept this status quo, he can only wait for him to go a few more times and let him die of this heart.

After Mu Yu walked twice, his mood began to become irritable, and it was not a way to go on like this. Lao Tan has walked so many times, he is much more experienced than himself, but he still hasn't gone out, and it is even more impossible for him to go out if he is so stupid. He sat down and practiced the Dust Falling Mind Method to calm himself down.

Xiao Shuai shook his tail and said, "I remember this formation, if I guessed correctly, this formation should be a mirror formation, I heard the white-bearded old man talk about it a long time ago." ”

"What is the Mirror Array?" Mu Yu hurriedly asked.

Xiao Shuai tilted his head, thought for a long time, and then explained: "To put it in layman's terms, the mirror array is a straight road with a mirror at each end, and if you walk along one road, you will go directly to the mirror, and then come out of the other mirror." So you'll keep walking back and forth on the road, and you'll have to find these two mirrors to get out. ”

A bright light flashed in Mu Yu's mind, and he suddenly understood how to crack this formation!

He deliberately walked around the river bank again, and unlike just now, this time he counted the number of steps.

He began to ponder for a moment, first walking about a hundred steps away from the green mist before throwing the vine away. It was about 2,645 steps from the vine to here, and it was 1,350 steps to walk forward to the vine from here, which means that it was about 4,000 steps to walk around this maze by yourself.

All formations must have a boundary, and as long as this boundary is found, it is easy to find a way out. This boundary is the two mirrors of the mirror array that Xiao Shuai said.

But how do you determine the location of this boundary?

Mu Yu stopped to observe the changes around him after taking a step, and if it was a boundary, then there would definitely be some flaws left on the left and right sides of the boundary, such as a fault in the dirt and stones on the ground.

Mu Yu spent a day searching the ground for four thousand steps, trying to find something wrong, and he was a little disappointed.

In this way, maybe the arrangers have noticed this problem a long time ago and erased the anomaly.

"That's right, find a marker!"

Mu Yu slapped his thigh, and he suddenly thought of a solution. This section of the road is in a straight line, about three steps is one meter, that is, more than a thousand meters. If there is a discernible marker in the center of this road, then you only need to walk backwards in front of this marker, and when you can't see this marker, it means that you have passed the critical line and returned to the starting point.

He hurriedly told Xiao Shuai what he thought, but Xiao Shuai blinked his innocent eyes and asked, "Then what are you looking for as a marker?" The fog here is so big, two meters away, people and animals do not distinguish between six relatives and relatives, what do you expect to see. ”

Mu Yu opened his mouth, and was deflated before he could rejoice. Xiao Shuai is right, it is foggy during the day, and even if you put a fire in the daytime, you can't see it! At night, there is still a little possibility, that night the fire on the other side of the river, they can see a vague fire from afar, and the fire light is still very penetrating at night.

However, there are monsters at night, and the firelight will lure the monsters in the river ashore, which means that the ignition must bear the risk of being attacked by monsters. What is the strength of the demon beasts in the river, Mu Yu has not yet understood, but according to Lao Tan's description of the demon beasts, the demon beasts in the river are definitely not vegetarian little sheep, this can be determined. Lighting a fire at night is undoubtedly tantamount to playing with fire and setting yourself on fire, and the situation will only be worse.

Mu Yu only thought of this method now, and he ran back to discuss his discovery with Lao Tan. Lao Tan listened to Mu Yu's explanation for a long time, and finally understood what Mu Yu was trying to express, and a look of hope suddenly appeared in his eyes.

"You're such a genius! I've been sleepy for more than half a year and I haven't thought of this solution. Tell us how you plan to implement it, and we can try to do it. ”

Lao Tan is actually very jealous of the demon beasts in the river, but if he has been trapped for so long, if he can't find a way out, then he will be trapped here for the rest of his life. Rather than doing this, it is better to fight! As long as he can get out, he is willing to try no matter how dangerous it is.

"The only thing we can use as markers now is flames, and there are no trees here, so we can only use Dan flint. Dan flint needs spiritual power to maintain the flame, that is to say, there needs to be a person in the center of this path to maintain the flame of Dan flint, the flame is too small to be invisible, so the flame must be maximized. But this will also bring serious problems, the flames will attract demon beasts, and the person holding the Dan flint will be very dangerous. ”

Mu Yu hesitated for a moment, and solemnly pointed out the loopholes in this plan. He can actually control the burning of plants, but if there are many plants that should not exist here, it will arouse the suspicion of Lao Tan, no matter what time it is, Mu Yu does not want to expose his ability to control trees.

His plan was not perfect, because the person who maintained the flame would have to take great risks, and would need to face the attacks of all the demon beasts, and it was even very likely that he would be buried in the belly of the demon beasts and become a delicacy for the demon beasts. Once something happens to that person, the Dan flint will be extinguished immediately without the blessing of spiritual power, and the only marker will lose its effect.

And the other one who wants to determine the critical line must walk in the dark, walking in the dark, it is inevitable that he will encounter demon beasts, and he will definitely not be better than another person when he can't see it.

It can be said that the risks faced by these two people are actually the same, and if one person makes a mistake, then the whole plan will be ruined.

Old Tan also thought of this, in fact, he immediately realized that the person who maintained the flame had to be him. The person who maintains the Dan flint is equivalent to telling all the demon beasts their exact location, and they must have a fight with the demon beasts. His strength is high, and he can hold on for a while under the siege of demon beasts, and his spiritual power is stronger than Mu Yu, and the flames will be more vigorous.

But can Mu Yu avoid other demon beasts in the dark? You must know that these demon beasts only come out at night, so their night vision ability is very strong, Mu Yu only has the strength of the Jindan period, can he withstand the attacks of these demon beasts?

Neither of them spoke, this plan was very risky, and the consequences of any accident were unimaginable. If something happens to the person who keeps the flame, the person looking for the critical line loses his sense of direction, he can't fly here, he can't find a place to stay in the dark night, he waits for death, if something happens to the person who is looking for the critical line, and the person who keeps the flame can't be sure if something has happened to the other party, then should he continue to maintain the flame or find a place to hide?

"The most important thing is that even if I find the tipping line, I'm not sure I'll crack it. Mu Yu finally said, pushing this plan into a dilemma. It's like a semi-final, even if you make it to the final, you're not completely sure you're going to win, but if you don't make it to the final, you don't even have any hope of winning.

"I'm going to give it a try. Old Tan said in a condensed voice.

He has been trapped here for too long, if he doesn't try, he will never be able to get out, the aura here is so thin, if he wants to cultivate to the out-of-body period, it is estimated that he will not be able to reach it for a lifetime, he must try, if he tries, he may die, but if he doesn't try, he will definitely wait for death.

Mu Yu nodded, he had to try, he still had a lot of time waiting for him to squander, but he couldn't plant it in this place where birds don't.

After the two decided, the next step was to discuss more details, and after everything was decided, they began to recharge their energy and quietly wait for the night to come.
