Sure enough.

Hearing this, Du Guanshan also laughed angrily.

"What a fearlessness for the unknown! Instead, ask Liao Wantong what kind of investment is needed to rebuild a formation corridor! ”

Yang Yu immediately looked at Liao Wantong, but saw that he was constipated.

"The formation corridor is not worth the buildings and assessment formations, but the four-star array that maintains the operation." Liao Wantong coughed dryly, and could only explain, "When the Formation Court was established a thousand years ago, it is said that in order to build and maintain the Great Array, the guild sent a total of three four-star array mages, and cooperated with five four-star heavenly engineers, and it took three years to complete the construction. ”

"Won't it?" Yang Yu was stunned, "How much does it cost?" ”

"To maintain the operation of the formation, ten thousand spirit stones are needed as an energy source every year, and the cost of building it is not less than one million spirit stones." Liao Wantong sighed.

This time to repair the formation corridor, it can be said that the budget has already emptied the family foundation of the formation court for many years.

If it weren't for the trip to the secret realm, how could Liao Wantong treat it as nothing?

Yang Yu was also drunk after hearing this.

I didn't expect that I accidentally burned a large amount of money.

When I looked at Liao Wantong again, I realized that the dean was under a lot of pressure for himself.

Since the formation was broken by itself, it naturally can't be treated as if nothing happened.

"Dean Liao, do you have a four-star array flag?" Yang Yu asked.

"Yes." Liao Wantong nodded.

"That's fine." Yang Yu smiled slightly, turned his head to look at Du Guanshan, "If I can build another four-star maintenance array, will it be nothing?" ”

"You're a one-star array mage, and you want to build a four-star array? Are you kidding? Du Guanshan almost laughed and lost his head.

"I'll ask you, yes or no?" Yang Yu stared at him, still asking the same question.

"How many years, ten years, are you going to build? Twenty years? Or a hundred years? Du Guanshan snorted coldly and said, "I don't have time to talk nonsense with you." ”

"No need, just one broken formation, at most a stick of incense can be done." Yang Yu waved his hand.

"Yang Yu Xiaoyou, you ......!" When Liao Wantong heard this, he almost fainted directly.

Now it's in big trouble!

If you say it, you can't collect the water you spilled.

Although there is a threat in the Duguan Pass, there is no real evidence, as long as everyone works together, they can still negotiate the conditions after all.

Now that you are speaking wildly, are you not digging a hole for yourself?

After a stick of incense, you want to build a four-star array?

Even the leader of the Array Mage Guild was sitting here, and he didn't dare to say such a big thing.

So even if Yang Yu was a formation wizard, Liao Wantong would never believe that he would be able to do it.

Others had the same idea as Liao Wantong, they all felt that Yang Yu was no longer in the brain, and the brain was full of soy milk, and chili powder was specially added.

"Since you're so confident, don't say I didn't give you a chance." Du Guanshan looked at Yang Yu like a fool, and said with a smug smile, "One stick of incense time, if you can succeed, I will immediately turn around and leave, and I will not pursue this matter again!" ”

"U-turn and leave?" Yang Yu smiled, "You brought your students here to spread wild, if you let you run away like this, wouldn't my Nanxuan Academy be easy to bully?!" ”

"And what do you want?" Du Guanshan narrowed his eyes, and a cold light flashed in his eyes.

"Today, in front of all the deans, I'll make a bet with you!" Yang Yu said confidently: "If I can't build the same four-star maintenance array as before in a stick of incense, I will be at your disposal; But if I do it, not only will the Array Mage Guild no longer be held accountable from now on, but you will also not be allowed to step into the Southern Xuanxue Mansion for half a step in this life and this life! If you dare to disobey the contract, even if you get into trouble with the Array Mage Guild, I will definitely let you win or lose! ”

After that, Yang Yu pouted and smiled: "If you don't dare to bet, I will also save a little face for you, you don't need to kneel down and slap like your apprentice, just get out of the house immediately!" ”

"Okay, that's it!"

The dean of the dignified martial arts academy, a four-star array mage, when has he ever been humiliated by someone pointing his nose like this?

Du Guanshan was so angry that he agreed without thinking about it.

Everyone looked at each other.

Yang Yu said this, which had completely angered the other party, leaving no room for negotiation at all.

Today's matter is no longer solvable.

Seeing this scene, Sima Yi secretly sighed.

Although Du Guanshan is in the Southern Metaphysical Academy, he is also a dean of the Northern Metaphysical Academy.

What's more, his identity on this trip is still an inspector of the Array Mage Guild.

You can't bully him with more and beat him up, right?

Therefore, even if you come forward as the dean now, there is no way to solve it properly.

Ding Boran stood beside him all the time, silent.

At this time, seeing that the teacher actually agreed to this kid's bet, I don't know why I had an ominous premonition.

Because before, he was fooled and lame by Yang Yu in this way.

……

When assessing the one-star array mage, Yang Yu only saw the formation diagram of one to three stars in the library pavilion, and he didn't know much about the four-star formation.

If it was another four-star formation, he would have to go to the Dean's Building to read the book.

But this four-star maintenance array, he had already used the system to carefully deduce it when he was sabotaging it yesterday, and he had also established a 3D model.

So for this formation, it can be said that he knows everything about it.

Everyone walked out of the living room and found an open place, Yang Yu asked Liao Wantong for dozens of four-star array flags, and directly began to set up the formation.

"Teacher, this kid is very evil, he dares to bet with you, I'm afraid he came prepared."

thought that Yang Yu was just bragging, but seeing that he was doing well at this time, Ding Boran couldn't help muttering.

"Hmph, I didn't even need a compass, so I started to lay out the array flag, it's just nonsense!" Du Guanshan said disapprerovingly, "You are also a three-star array mage, when have you ever seen someone do this?" ”

How could it be so easy to build a four-star maintenance array?

This not only requires the formation mage to be familiar with the formation, but also requires repeated surveys of the terrain to find a suitable formation eye.

Even for him, it would take at least a few months just to determine the formation eye.

Otherwise, as long as there is a slight mistake, once the aura is injected, it will not be activated at least, or it will be blown up directly.

If you just put a few array flags on the ground, you can build a four-star array, and the formation knowledge he has learned for so many years can be fed to the dogs.

Seeing that Yang Yu casually inserted a formation flag, then stood in place for a while, and then ran to another place, drawing a gourd in the same way, feeling like playing.

The deans stood not far away, and they all shook their heads.

"Great Dean, if the situation gets out of control for a while, please make a move, even if you offend the Array Mage Guild, you can't ruin the plan of the trip to the secret realm." Liao Wantong begged Sima Yi in a low voice, "Big deal, when the time comes, let me go to the Array Mage Guild to take the blame." ”

Liao Wantong was so protective of Yang Yu, in fact, not only because Yang Yu was a once-in-a-millennium formation wizard, but also because he had a blood feud with the orc clan.

Everyone knows this, but it is not explicitly stated.

"Yes, Dean." Situ Shan also nodded and said, "Yang Yu's matter, I will let the Jinghong Master Guild come forward to coordinate, but I must not let Du Guanshan take him away today." ”

"Originally, this matter could still be dealt with." Sima Yi's face was embarrassed, and he sighed and said, "But just now he made a lot of nonsense, and you didn't hear it." In my opinion, Du Guanshan will never give up today. ”

"I don't care, it's not that easy to take him away." Hua Jianbo snorted lightly and said, "He brought his disciples to the Martial Arts Academy to provoke, he was rude first, if he had to tear his face, I, Hua Jianbo, would not be easy to provoke." ”

"That's it, call it a day."

Just as everyone was talking in a low voice, Yang Yu had already inserted the last array flag into the ground.

I saw him pick up a stone at random, draw a big circle on the ground somewhere, then clapped his hands, and looked at everyone with a smile.

"Done?" Du Guanshan laughed, and then his face sank and said, "If you just put a few array flags on the ground, even if you succeed, a fool can do it." The content of the bet is that you must activate the formation, not! ”

"It's easy." Yang Yu disagreed, and said to Liao Wantong, "Dean Liao, you need spirit stones to activate the formation, you give me two thousand spirit stones, and I will activate them for him." ”

Two thousand spirit stones, it may be a lot for ordinary people.

But against the courts, it's all stress.

Now the two sides bet, although Liao Wantong didn't believe it, he immediately took out two thousand lower grade spirit stones.

Yang Yu took the spirit stones and threw them into the circle he had drawn before.

Immediately after, I saw him step under his feet.

Everyone only heard a buzz, and the spiritual energy contained in the two thousand spirit stones in the circle was immediately pulled by some kind of force, and rushed in all directions, landing in these arranged array flags.

A majestic array has actually begun to operate in an instant!

"This ......"

When everyone saw this scene, their jaws fell to the ground, and even their eyes fell to the ground, and their expressions were terrified.

……
