It was dark outside, but there was light not far away, as if someone had lit a fire. According to the distance of the light, the man should be on the opposite side of the river bank, and from time to time there were a few vague calls of abuse. Then there was the green light flashing around, which was the light of the man's magic weapon. It seemed that he had a close fight with whom.

"Is that the man who came in with you? He shouldn't light the fire. All the monsters in the river climb up at night, and he will be besieged. " Old Tan said faintly that the people on the other side did not know that there would be monsters in the valley at night. As soon as he ignited the fire, he would completely expose his position in front of all the monsters.

Muyu doesn't know what the so-called monster is, but he is glad that he met Lao Tan, otherwise he is expected to fight with the monster below tonight. That person is a yuan infantile period, can persist, he is only the golden elixir cultivation, where can insist so long.

"Can we help him?" Although the man's attitude towards Muyu is very bad, if he can stay together in this ghost place, he will have more chances to survive.

"Help? How to help? If he is smart, he will be destroyed by fire, otherwise more and more monsters will be attracted to him, and then he will die. " Old Tan shakes his head and returns to his cave. At such a long distance, you can't fly. You can't see the situation clearly. No one will know when you hit.

Muyu thinks about it, and now he is really watching the fire from the shore. The man couldn't get out of danger when the fire was still there.

Fortunately, after a while, the man seemed to realize the problem. The fire on the other side of the river suddenly disappeared, leaving only the light of the magic instrument. After a while, the light of the magic instrument also disappeared. I don't know whether the man deliberately did not shine or was buried in the mouth of the monster, and peace was restored around him. Muyu sat back in the cave. For today's plan, he had to rest well and make plans for tomorrow.

Muyu didn't sleep well this night. He tossed and turned for a long time before he fell asleep. Then he had a strange dream. He dreamed that he was trapped in this ghost place all his life, and finally he could not bear loneliness and wanted to commit suicide. Then he saw that Feng HaoChen came to stop him. Before he could be happy, the people from the triple palace came. Feng HaoChen was caught by them. Muyu reached out to rescue him. Then he touched the wall of the cave and woke him up with pain.

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

It's still a big fog around. Old Tan wakes Mu Yu and tells him it's almost noon. Muyu looked outside and thought it was early morning. They stayed in the hole all the time, so they climbed down. At the Bank of the river, Muyu opened his eyes to see the situation on the opposite side. Unfortunately, the visibility was too low and the vision was seriously suppressed.

Muyu washed his face by the river. The river was cold, which made him wake up a little. He wanted to try again. Lao Tan told him that it was futile, but Muyu was not reconciled. He ran forward this time, needless to say, he came back after a circle.

"I've tried it many times. It's too much to do with it." Old Tan said calmly that he was not reconciled to it. After dozens of times, he was finally disheartened. Now he is used to it. He knows that if he wants to let Muyu accept the status quo, he has to wait for him to go a few more times to let him die.

Muyu walked twice again, and his mood began to get irritable. It was no way to go on like this. Old Tan walked through so many times, he had more experience than himself, but still did not go out, he was so stupid to go out more impossible. He sat down and practiced the falling dust mental method to calm himself down.

The little Marshal wagged his tail and said, "I remember this kind of array. If I guess correctly, this array should be a mirror array. I heard the old man with white beard talk about it a long time ago."

"What is a mirror array?" Mu Yu asked in a hurry.

Xiao Shuai tilted his head and thought for a long time. Then he explained: "generally speaking, mirror array is a straight road. If you walk along one road, you will go directly into the mirror and come out from the other mirror. In this way, you will be walking back and forth all the time. If you want to go out, you must find these two mirrors. "

A bright light flashed through Mu Yu's brain, and he suddenly understood how to crack the array!

He went around the river bank again, but this time he counted the steps.

He began to think about it. First of all, he left the green fog and walked about a hundred steps before throwing the vine away. It's about 2645 steps from the vine to here, and 1350 steps from here to the vine, that is to say, it is about 4000 steps to walk around the maze.

Every array must have a boundary. As long as you find this boundary, it's easy to find a way out. This boundary is what Xiao Shuai called two mirrors of the mirror array.

But how to locate the boundary?

Muyu stops to observe the changes around him. If it is a boundary, there will be some flaws on the left and right sides of the boundary, such as faults in the soil and stones on the ground.

Muyu spent a day searching 4000 steps of the ground to find something wrong, but he was disappointed.In this way, the indefinite array setters have noticed this problem for a long time and wiped out the anomaly.

"By the way, find a sign!"

Muyu clapped his thigh, and he suddenly thought of a way. This section of the road is a straight line, about three steps into a meter, that is, more than 1000 meters. If there is a sign that can be identified in the center of this section of road, as long as you walk backward in front of the sign, when you can't see the sign, it means that you have passed the critical line and returned to the starting point. According to the principle, the sign should be behind you, so that you can determine the critical line.

He quickly told his thoughts to the little marshal, but he blinked his innocent big eyes and asked, "what are you looking for as a marker? It's so foggy here. People and animals don't recognize each other two meters away. What do you expect to see

Muyu opened his mouth, and was frustrated before he could be happy. Xiao Shuai is right. It's foggy in the daytime. You can't see it even if you set a fire during the day! At night, it was possible that they could see a blur of fire on the other side of the river that night. The fire was still penetrating at night.

However, there are monsters at night, and the fire will lead them ashore, which means that the fire must bear the risk of being attacked by monsters. Muyu has not yet learned about the strength of the monster in the river. However, according to Lao Tan's description of the monster, the monster in the river is definitely not a vegetarian lamb, which can be determined. Lighting a fire at night is no doubt tantamount to self Immolation, and the situation will be worse.

So far, Muyu only thought of this method. He ran back to discuss his discovery with Lao tan. After listening to Mu Yu's explanation for a long time, Lao Tan finally understood what Mu Yu meant. His eyes suddenly showed a look of hope.

"You are a genius! I was sleepy for half a year, but I didn't think of it. Let's talk about how you plan to implement it. We can try it. "

In fact, Lao Tan is also afraid of monsters in the river, but he has been trapped for such a long time. If he can't find his way out, he will be trapped here all his life. It's better to fight for it! As long as he can go out, he is willing to try anything dangerous.

"The only thing we can use as a marker now is fire. There are no trees here, so we can only use danhuoshi. Danhuoshi needs spiritual power to maintain the flame, that is to say, a person is needed to maintain the flame of danhuoshi in the center of the road. If the flame is too small, it may not be seen, so the flame must be maximized. But at the same time, it will bring serious problems. The flame will attract monsters, and the person holding Dan Huoshi will be very dangerous

Mu Yu hesitated for a moment and seriously pointed out the loopholes in the plan. In fact, he can control the burning of plants. However, if there are many plants that should not exist suddenly, Lao Tan will suspect that Mu Yu does not want to expose his ability to control trees at any time.

His plan is not perfect, because the person who maintains the fire has to bear great risks, and needs to face all kinds of monster attacks. He may even be buried in the monster's belly and become a monster food. Once that person has an accident, Dan Huoshi will be extinguished immediately without the blessing of spiritual power, and the only symbol will lose its function.

In addition, if you want to determine the critical line, you must walk in the dark. If you walk in the dark, you will inevitably encounter a monster. If you can't see it, you will never be better than another person.

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

Old Tan also thought of this, in fact, he immediately realized that it must be he who maintains the flame. The person who maintains Dan Huoshi is equivalent to telling all monsters their exact location. They must fight with them. He has high strength and can persist for a while under the siege of monsters. Moreover, his spiritual power is stronger than Muyu, and the flame will be more vigorous.

But can Muyu avoid other monsters in the dark? To know that these monsters only come out at night, then their night vision ability is very strong, Muyu only has the strength of the golden elixir, can withstand the attacks of these monsters?

Both of them did not speak. This plan is very risky, and the consequences of any accident are unimaginable. If the person who maintains the fire breaks down, the person looking for the critical line will lose his sense of direction. He can't fly here, and if he can't find a place to live in the dark night, he will die. If the person who looks for the critical line has an accident, and the person who maintains the flame can't be sure whether there is something wrong with the other party, should he continue to maintain the flame or find a place to hide?

"The most important thing is, even if I find the critical line, I'm not sure to crack the array." Muyu finally said, pushing the plan into a dilemma. It's like a semi-final. Even if you're in the final, you're not sure you'll win, but if you don't get to the final, you don't even have a chance to win.

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

He has been stuck here for too long. If he doesn't try, he will never get out. The aura here is so thin. If he wants to practice until he is out of the body, he may not be able to reach it in his whole life. He must try. He may die if he tries, but he will surely wait for death if he does not try.

Muyu nodded, and he had to try. He still had a lot of time to spend. He could not plant in this place where the birds didn't poop.After the two decided, the next step was to discuss more details. After everything was confirmed, they began to gather their energy and wait for the dark night to come.
