"Ding, consuming ten points of energy, has embodied the most cost-effective power grid layout map that can meet the defense needs of Jinyang City."

The black character pattern slowly appeared on the huge white scroll, and the main god immediately embodied a map of the power grid layout of Jinyang City, but it only cost ten energy points.

Pinching this thin scroll, Chu Fan only felt that it was extremely heavy.

On this one scroll, the price is already comparable to the vehicle off-road vehicle that Chu Fan parked outside.

"Sure enough, knowledge is power." Chu Fan couldn't help but sigh.

A clear grid layout is drawn on it, and the data is converted into the arithmetic of this world, and each location, how big, how wide, and how far away from other power grids are clearly marked.

"It's just that I don't know if the price of 100,000 spirit stones, plus the various heavenly and earthly treasures in the Overlord Body Cultivation Manual, will be too high."

Chu Fan thought for a while, and set the price according to the price of the general period of the world city formation in the encyclopedia, because the materials needed for the formation could be raised, Chu Fan added various cultivation pills, herbs, and the flesh and blood of many types of demon beasts, I was afraid that these heavenly and earthly treasures would ask for too much, and the number of spirit stones needed for the power grid would also be reduced.

Chu Fan handed over the scroll to the city lord's subordinates, and at the same time, another sect in the attic also handed the scroll up.

"Senior brother, why do we choose the formation so carefully and lower the price so much!"

The female disciple wearing the dark cyan True Heaven Sect costume was very puzzled, obviously the other five sects found the formation at random and handed it over, why did her senior brother choose carefully for the situation in Jinyang City.

"Although Jinyang City is a little more dangerous, but at the moment, this city is in great need of a suitable formation to protect the city, and the price given by Jinyang City is nearly twice as high as usual, which can be used for nearly a year's expenses from all over the sect to our sect, which is a win-win move." Senior Brother patiently explained.

"What the hell is this place, maybe when the demon clan will come to attack."

The woman in Tsing Yi looked slightly dissatisfied and muttered.

She didn't listen to her senior brother's explanation at all, she was just dissatisfied with the desolate place of Jinyang City.

And the city lord of Jinyang City looked at the scroll formation submitted by the True Heaven Sect, and his face was happy.

Finally, there is a suitable formation!

The rest of the formations were obviously perfunctory, and although the power and size were okay, the asking price was extremely high.

And it is specially noted that if the city protection array is built, every time the time is shortened by a month, how many spirit stones will be added.

Although it is not called taking advantage of this to make the Xuanwu country difficult to make money, it is also beyond expectations, and it is not too easy to accept.

And the True Heaven Sect's city protection thunder array is the first choice among the six sect protection formations, and the construction period is also the shortest.

The price requirements are also more reasonable, 200,000 spirit stones plus various materials for building the array,

Although it is still a little more expensive than the normal price, it is much better than several other sects.

"It seems that the Great Array of City Protection will be undertaken by the True Heaven Sect."

The city lord of Jinyang City looked happy, and his back straightened.

"Well, that's true."

The City Guards watched with the City Lord of Jinyang City on the side, nodding in agreement.

Seeing this scene, a total of more than 60 sect disciples in the attic also knew who had auctioned the auction of Jinyang City's protective array, and they all immediately had a look of resignation.

"There's also a scroll handed over by the agency, so you might as well read it."

City Guards was a man with a thin face, and he was more impressed by Chu Fan, who was also thin in appearance.

The city lord of Jinyang City suddenly remembered that there was also Chu Fan, and he also decided to take a look at the process and give respect.

The city lord of Jinyang City casually picked up Chu Fan's scroll worth ten spirit stones, and his gaze fell on it.

Seeing that Chu Fan was still drinking tea on the second floor, the city guard only felt that this person had some indescribable strange feelings.

In the martial Four Spirits Continent, ordinary people will do some fist and foot kung fu, and if they have some money to spare, they will also buy a few pairs of herbal refining bodies, which also has a bit of momentum.

I'm afraid the city guard will get used to it.

But Chu Fan is clearly an ordinary person in his twenties who has never been refined.

Moreover, the expression and demeanor are calm, as if it should be, and people should be like this.

"With such fine skin and tender meat, how can you wander around the border of Xuanwu Country at will?"

"Could it be that you really rely on that strange thing that consumes a lot of energy?"

In the heart of the City Guard, he has lived in the Yuan Infant Realm for one hundred and eighty years and has never seen a person with such a temperament as Chu Fan, and he feels just... Like a sheep with Erlang's legs crossed in a wolf pile, it was hard for him not to pay attention.

Suddenly, he realized that the face of the city lord beside him was wrong, and his huge body trembled slightly.

"Could it be that you were angry with the extremely high spirit stone budget of the agency family?"

Although the things invented by the agency are ingenious, they also cost a lot of spirit stones.

The city guard couldn't accept the price when he was only the city lord, so he hurriedly looked at the scroll.

After looking at it for a while, the whole person's complexion also changed.

"How... So low! ”

"How can it be so fast!"

It's the same thing they think.

Although the formation diagram depicted on the scroll was similar, it was very strange, and he couldn't understand it.

But it doesn't matter, just look at the power of this formation, the cost, and the expectation of how long it will take to engrave the formation.

"Only 100,000 spirit stones are needed, which is fully double that of the lowest True Heaven Sect!"

"And these materials are also weird, not like a refining array, more like a refining body, but there are a lot less than the usual array materials."

"But I haven't heard of the need for a large amount of demon beast flesh and blood, so it's possible... Is it needed for the formation? ”

A series of question marks appeared on the faces of Jinyang City and the City Guard, and the two looked at each other.

I thought it would consume the most energy, but it seems to have become the biggest dark horse.

You must know that the ordinary tricks in this world cannot be compared to traditional cultivation and formations at all, although they are powerful and can replace cultivators to a certain extent, but they consume a huge amount of energy.

In addition to the divine arm crossbow, chain crossbow and other weapons equipped with a large number of low-level martial arts of the Xuanwu Kingdom, only the wooden ox flowing horse and the flying boat are barely popular among the nobles of the upper class of the Xuanwu Kingdom.

"It can't be!"

The same thought came to the minds of the two of them.

But the military law of the Xuanwu Kingdom is strict, and Chu Fan seems to be just an ordinary person, and he can't come to Jinyang City to die a hundred miles away.

Thinking of the wooden ox and flowing horse that Chu Fan rode again, maybe this "power grid formation" is real?

So the two of them watched patiently for a long time.

The more I look at it, the more I feel that this method is exquisite, and everything is clearly marked.

The two of them only felt that this was a thunder array similar to that of the True Heaven Sect.

Faster and stronger, though!

If it is really the same as the scroll says, the power can resist the out-of-body stage monks, then this "power grid" formation is a top formation in the entire Xuanwu Kingdom!

"Little brother, what is said on this scroll... But really? ”

"Nature is true." Chu Fan said.

The city lord and the city guard had serious faces, and Chu Fan didn't expect his drawings to make the two of them attach so much importance to them.

"The power of a second-level scientific and technological object is naturally incomparable to the formation of this small city." Chu Fan said secretly in his heart.

"If it's true, then there is Brother Lao Chu."

"However, do you know that if the formation is too far from what is expected, it is a capital crime in the Xuanwu Kingdom!"

The City Guard's tone changed sharply.
