Muyu brought back 20 purple gold spirit stones, which will be used. Looking for the old skillfully set up an array in which all the spirit stones needed for the spirit gathering array were concentrated on a purple gold spirit stone. According to the estimation of looking for the old, the purple gold spirit stone can be used for at least one year.

"I have 20 purple gold spirit stones. Don't I say they can be used for several years?" Muyu exclaimed, and he remembered that he had used up all the other purple gold spirit stones. He was a little embarrassed.

Xun Lao replaced the spirit stone that had become ordinary stone with purple gold spirit stone, and then stood up. After a busy afternoon, he finally transformed the four arrays. He said, "let's do it now! Give me a few more days, and I can use two purple gold spirit stones to transform the spirit gathering array, and the effect will be doubled. "

"What did you say we had a mountain protection array in Luochen mountain?" LAN ling'er has been asking the East and West all afternoon. Mu Yu never knew that she was so interested in the array.

After thinking about it for a while, he said, "the array of Luochen mountain is very advanced. I haven't seen it before. However, I guess that this array is to lock the aura of the outside world on this mountain, making the aura of the mountain more mellow, similar to the spirit gathering array, but much higher than the spirit gathering array. If you can control this array, you can even observe the movements of all the people on the mountain, you can also use this array to prevent outsiders from invading, and you can also use this array to attack everyone in the mountain! "

"So good?" Mu Yu opened his mouth, and master quietly put up such a secret and powerful array? Did he not say that anyone who practices laziness can't escape master's eyes?

"Isn't this big array asking for more spirit stones?" LAN ling'er also thinks it's incredible that a small place needs 500 spirit stones. The array of Luochen mountain is so large, isn't it hundreds of thousands?

"This array is very strange. It's not like using spirit stone as the base, but something as the base. It may be a magic weapon. I'm not sure. If it is the array set by the leader, his understanding of the array is much better than mine. " Looking for the old exclaimed.

Some magic weapon? What kind of magic weapon can support a mountain protection array?

"Looking for the old, I remember that the Jiuhua sect also has a big mountain protection array. Do they have any powerful magic weapon?" When Muyu wanted to sneak into the Jiuhua sect, he touched the mountain protection array and was found to have to leave.

Looking for the old man to shake his head: "Jiuhua sent me to visit several times. That big array is just a simple warning array. It is not aggressive and can't gather aura. When someone doesn't get in the right way, it triggers an alarm. That array needs only a few hundred spirit stones a month. It doesn't need too much. It's the same as that of other schools in the University. "

Every other school in the university has an array, which needs to be entered in a specific way, otherwise it will make a beep. There is also this array in Luochen sect courtyard. Muyu and they all know how to get in.

Muyu wanted to ask what he wanted to ask, but at this moment, Xulao suddenly gasped for breath. His whole body trembled, his face showed a look of pain, and his hands tightly grasped his chest.

"Looking for the old, what's the matter with you?" Mu Yu asked in a hurry.

"Kill, kill, I I didn't eat, eat, eat for days... " Looking for old pain to fall on the ground convulsion, his eyes become red, the whole body joints began to bulge deformation, some frightening.

"The soul eating wolf in the old man's body has broken out. Go to Uncle an and he says he has a way to suppress it!" Muyu said to lanling'er. LAN ling'er nodded and flashed out. After a while, he brought uncle an to come.

"Uncle ANN, what to do?" Mu Yu asked anxiously. For the past two days, he has been healing his wounds and clearing away the hidden diseases in his body. Because he took the spirit of wolf, his body recovered quickly, but he still failed to suppress the wolf's wolf nature.

Uncle an took out a black grass without any expression, shook it into powder and put it into the mouth of looking for the old man. Muyu knows that this black grass, which is called Stellera chamaejasme, is planted in Shifu's medicine garden. Shifu will plant various kinds of herbs for them to take a bath. Usually, people don't care about these herbs.

"The wolf poison grass is the enemy of wolf beasts, which can suppress the wolf nature of wolf spirits. The leader planted some, and then took one every seven days Uncle Ann said quietly.

Looking for the old face gradually slowed down, his chest slowly became stable, the red light in his eyes also dispersed, after a long time, he sat up: "thank you, thank you, Lord Ann."

"The leader of Stellera chamaejasme doesn't grow much. Muyu, you can find a way to solve it." Uncle an takes a meaningful look at Mu Yu. Mu Yu is not comfortable. Uncle an says this to mean that he knows Muyu has the ability to control wood.

"I'll do something about it." Mu Yu laughs. He thinks his ability is only known by his master and elder martial brother, but Uncle an has known it for a long time.

Uncle an turned to leave when he saw that he was all right. After a few steps, he stopped again and said, "looking for old man, I agree that you stay because you helped Mu Yu a lot. But I don't like what you did in the past, so you can do it yourself."

Looking for the old face a burst of red and white, he sighed: "I remember."

In fact, when Xulao was betrayed by his trusted grey disciples, he already knew how ridiculous what he had done. In order to make the grey disciples of the Academy live better, he killed so many arrogant practitioners, but in the end he was betrayed. Now Muyu lets him stay in the falling dust sect. He joins a sect as he wishes. What else can he not do?"There is another reason. Mu Yu said that you have studied the formation. Have you ever heard of the Dragon seeking array?" Uncle Ann asked.

"Looking for the dragon? What are you looking for? " The old man's face changed slightly.

"What is dragon hunting array?" LAN ling'er asked curiously.

"Dragon searching array is to set up a new array. It can help you find what you want to find, including people." Looking for the old man to explain.

"Looking for someone? Really? We're looking for someone right now Mu Yu can't wait to say.

Looking for the old man to shake his head, said: "I can set up the Dragon search array, but the price is too high, I'm afraid we can't collect materials. Moreover, the guidance of the Dragon seeking array is too harsh. I don't recommend you to use the Dragon seeking array."

An array includes formation, base, eye and guide. Array shape determines the structure and size of an array, which is not fixed. Array eye is the core of an array. Each array has an array eye, which controls the effect of the whole array. One of the most effective ways to break the array is to destroy the array eye. The array base is to provide Aura support for the array. Generally, the spirit stone is used as the array base, and some natural materials and earth treasures can be used as the array base.

The array guide is not required by all arrays. Some powerful arrays can be used. The array leader can extend the effectiveness of the array beyond the array, and control an array to work in a far distance. For example, people in the array can attack people outside the array.

"What does the Dragon search array need to be a guide?" Muyu ran with the old man for the whole afternoon, but also vaguely knew some common sense of the array.

"If you want to find something, you have to use the same kind of thing as the guide." Looking for old serious said, "that is to say, if you want to find someone, you need to have a person to do the array guide. The Dragon seeking array acts outside the array, and its scope of action is determined by the quality of the array leader. If you want to find someone, then the person who makes the array guide needs to have strong willpower. Otherwise, you can only search for a very narrow range, such as a mile in a square. It's better to find it yourself. "

"I can be a guide." Uncle Ann said.

"If the Dragon search array is used to find people, the person who is the leader of the array is very dangerous. Once there is a slight mistake or disturbance, it will lead to the destruction of the array leader. That is to say, when the array leader is killed, his soul will be destroyed! " Looking for the old man, he looked at Uncle an seriously.

Mu Yu and LAN ling'er are all facial expressions changed, only uncle an is still expressionless.

"I'm willing to take the risk." An Shudao.

Uncle an is very strict with everyone. He is eccentric and does not get close to others. Only when he faces the leader, he looks a little like a normal person. No one knows about Uncle an's past, only that uncle an has been obedient and respectful to the leader. Since the leader's disappearance, he has become more reticent. He stubbornly believes that the leader's disappearance is his fault.

"How many levels of assurance do you have in looking for the old?" Mu Yu asked.

"The materials of the Dragon seeking array are very complicated. The base of the array can't be a spirit stone. There must be five things. Ten thousand years of Qingmu, xuanhai, Chenbing, Guling Lihuo, tianwai meteorite, sunken rock and frozen soil, all of which are extraordinary. It is said that the Dragon searching array was created by the five element Youmeng demon family, so the materials are inseparable from the five element exotic treasure. " Said the old man.

Don't mention these five things. Muyu has never heard of them. What is Wannian Qingmu? Muyu doesn't know anything else.

"How to find these things?" Lanlinger doesn't understand this at all.

Looking for old shake his head, some helpless way: "I have not seen."

Uncle an was silent for a long time and said, "I have all the materials. You just need to help set up the array."

"What? Do you have all these materials? " It's unbelievable to find the old man. He also heard about the method of searching for the Dragon array from ancient books. He didn't know what these materials were. But Uncle an said that he had all of them. Was he kidding?

"Don't worry. I'll get the materials ready for you. I'll come to you in two days." Uncle an said concisely and turned away from the falling dust cliff.

Mu Yu feels strange in his heart. How can uncle an have all these things that seem to have been made of? Uncle an's origin is as mysterious as Shifu's. We only know that he is unsmiling and loyal to the leader. Apart from his poor cooking skills, he really doesn't know much about it.

Mu Yu helps Xun go to rest. He leaves the room and goes out with LAN ling'er. However, he is thinking about the Dragon search array. If this dragon seeking array can help find the whereabouts of his master, he is willing to risk becoming the leader of the array. However, uncle an certainly disagrees. He is such a stubborn person that he will fight in person.

"Ling'er, I didn't know you were so interested in the array yet!" Muyu said casually.

"I'm interested in you, you big head." Lan Ling er said without a reason.

Muyu was scolded a little inexplicable: "you are not interested, why do you still follow us around in the afternoon?"

LAN ling'er hummed: "it's not you who are so stupid that you bring back a person casually and let him join our sect. Do you think we will accept him?"

Mu Yu is stunned. He thinks he has convinced everyone, but LAN ling'er seems to be worried about something."He killed so many people that, though they were too much, they would not die. I don't care about this. I'm mainly worried about the wolf in his body. I don't worry that he will turn into a wolf to attack you or me, but have you considered the emptiness and subtlety of being ignorant of the world? They don't have any accomplishments. If they are out of control and attack them, what will they do? " Lan Ling Er asked.

Muyu is speechless. He is really too bold to take this into consideration. Only he knew that even if he turned into a soul devouring wolf, he would not kill people. Other people didn't know that. They only agreed to Mu Yu's request temporarily for the sake of improving Mu Yu's accomplishments. This does not mean that he really trusts Xulao.

"But I don't think he is a bad man. He was once the deacon of the University. He was humble. That's good. I ran around with you in the afternoon just to get to know him. I didn't expect to find out the formation that we didn't even know. He was really not simple. " LAN ling'er has approved of looking for the old to stay.

"There are so many secrets in master's body that he never tells us, but we have discovered so much. We don't know if he will be unhappy." LAN ling'er continued.

"Let's make sure the safety of the master first." Muyu sighed at the empty reclining chair in the courtyard. In the past, master would sit there every day to keep his eyes closed.
