Afternoon.

On the outskirts of the village of Philand, barren clearing.

Rosen carefully explained his new construction principles to the civilian mages.

"It's actually very simple, it's divided into four steps."

"First, get the mud."

Rosen unleashed five slurry spells on the ground where the grass stems had been removed, turning large chunks of wet dirt into swamps.

"Second, drying."

A large amount of drying is carried out, and the mud is combined to form a clay with a water content of less than one percent.

"Third, get in shape!"

With the upgraded version of the Mage's Hand, the dexterity was also increased to the extreme, lifting a large amount of clay from the ground and turning it into a high wall in the manor courtyard according to the expected terrain.

The wall, which is 5 meters high, half a meter thick and 10 meters long, was shaped by the plastic surgery and maintained for a while, then temporarily maintained.

But the clay wall will certainly not last long, and it is estimated that it will deform or even collapse significantly in a few minutes.

"Fourth, petrify!"

Specifically, the Mithril Petrified Staff, a large amount of mist-like white light shrouded the stone wall, and only the sound of 'click~click~' like ice condensation continued to sound.

After about ten seconds, the clay wall completely condensed, forming an earthy gray solid stone wall covered with agate-like patterns.

Lawson unleashed a flying spell and jumped above the stone wall, looking down at the civilian mages below.

From the faces of the various mages, there was a strong sense of doubt, and even Lydia and Hal were not immune.

He could guess what the other party was thinking, because such a construction procedure was very ordinary and easy to understand.

The question is how to ensure that the final petrification effect lasts for a long time, and how to ensure that it is not easily dispelled.

Even, even if no one deliberately dispelled it, the disturbance of the weather alone, such as rain, snow and sunlight, was enough to make the spell effect quickly disintegrate.

Lawson smiled slightly and looked at Ladia: "Mage Ladia, how many dispel spells do you have?" ”

Lydia thought for a moment and said, "I will have three. ”

"They are the 'Purification' and 'Disintegration' of natural spells, and the 'Spell Unlock' of logic spells."

"So, please use each of the three spells to dispel this petrified wall."

He turned to look at Hal, who was eager to try, "Come too." ”

Hal laughed, "Rosen, I'll do it, but the Earl's original famous mid-level dispel spell 'Destitute'!" Are you really sure to block it? ”

"Just try."

So, two official mages stood about 30 meters away from the high wall, casting the dispel spell on the petrified wall, while nearly 300 unofficial mages watched with interest.

The first to strike was Ledia.

Lydia uses purification first.

I saw a clear light like water enveloping the stone wall.

After about ten seconds, the light dissipated, and a thin layer of dust appeared on the stone wall, and when the wind blew, the dust flew away, and the stone wall was still as bright as new.

"Hey~It's kind of interesting~"

She immediately switched to disintegration.

As soon as the thought moved, a dark green ray hit the stone wall, turning into a small emerald green shimmer like a spider web, and quickly swam around the surface of the stone wall.

A thin layer of dust appeared on the surface of the stone wall again, and when the wind blew, it was as bright as new again.

Lydia was dumbfounded: "I feel like my spell is working, but it hasn't fully worked. ”

Rosen stretched out his hand to invite: "Go ahead." ”

The third spell is the rare Logic Dispel 'Spell Unlock'.

As the name suggests, this spell is very targeted, like a key that can be easily unlocked if inserted into the right hole.

Otherwise, it may not be effective.

Lydia casts a spell with concentration.

Soon, the staff in his hand shot out a cone-shaped dark blue shimmer, enveloping most of the stone wall.

After more than ten seconds, the blue light disappeared, and the stone wall was unharmed, not even the surface dust appeared.

Rosen smiled, "It seems that you got the wrong key." ”

Lydia didn't speak, just stared at the stone wall, frowning and thinking.

Hal exclaimed, "Let me try!" ”

The Earl's original impoverished spell, a half-natural and half-logical spell, is extremely powerful, and the spell released by one cent of mana can dispel the spell effect of ten points of constant mana at most.

He raised the spell sword in his hand and pointed at the stone wall.

"Crash!"

A bright ball of lilac light burst out of the tip of the sword, flying rapidly around the surface of the stone wall, while continuously releasing lilac, lightning-like magic energy at the stone wall.

With each shot, there was an additional layer of dust on the stone wall that was struck by the purple lightning, and after a total of dozens of shots, the surface of the stone wall became cratered, as if it had been blown by hail.

However, only the surface is damaged, and the main body is still intact, which does not affect the normal function of the wall at all.

Halton was surprised: "This wall is really a bit weird, even the Earl's spells can't deal with it!" ”

Rosen smiled slightly, jumped on top of the stone wall again, raised his foot and kicked the wall, making a thick 'bang' echo.

"Two mages, if I said that it took me about 10 points of mana to solidify this wall, you probably spent 15 points of mana for the dispel technique just now, right?"

Lydia nodded: "That's about the same proportion." ”

Rosen said, "How much mana do you think it will take to completely dispel it?" ”

Lydia estimated the effect of the spell just now: "Why do you need two or three hundred points, right?" ”

Rosen nodded: "That's about the same number, that's twenty times the mana consumption ratio." ”

He glanced at everyone: "However, the wall I built with 1 mana needs 20 mana to disperse, so it is better to directly release the attack spell to bombard it head-on." ”

The attack spell released by 20 points of mana is slammed head-on, and the destruction effect is definitely greater than this dispel technique, so the dispel technique loses the meaning of dispel.

Hal nodded in agreement: "If you bombard it with 20 mana, even a real stone wall won't be able to stop it." ”

Then he asked, "Can you tell me why?" ”

Rosen didn't hide either: "Because of the dexterous spellcasting." ”

"Huh?" Hal didn't figure it out for a moment.

"It's also because one law breaks one law, and there are three dispersal rules at most."

Hal's eyes lit up, and he thought of something, but he didn't particularly understand it, so he couldn't say it at once.

Ladia had already figured it out.

"The same dispel spell can only dispel up to three different types of spells at the same time."

"And Lawson greatly reduced the scale of a single petrification technique through dexterous casting, and developed a large number of extraordinary versions of petrification, and then stacked it layer after layer according to certain rules."

Hal got it, too.

"So, the dispersal spell actually took effect, but because there were too many spells and too many spells, only part of them took effect."

Rosen snapped his fingers: "That's it." ”

He laughed: "Such a complex petrified wall may still not be used to build important buildings, but there is no problem in building ordinary houses, solidifying the road surface, and building water canals." ”

"Finally, I'll issue a decree in my territory that prohibits mages from using dispel spells in the town."

"Then with this petrification, you can replace ordinary construction techniques, not to mention the speed, and the cost is much lower than the town built by normal methods, but in the end, the town you get is more durable, beautiful and tidy."

Lydia and Hal listened with their mouths slightly open.

After a long time, Ladia said, "Rosen, you really dare to think about it!" ”

Hal thought about it for a moment and asked, "What if there is a bastard who specializes in developing dispersal techniques for petrification?" ”

Rosen naturally thought of it.

"It's a possibility, but I've set up a double spell lock for petrification."

Lydia's eyes lit up: "Spell lock, interesting." Explain it quickly. ”

Rosen was going to keep the secret open so that no one would try to crack his petrification.

At this point, explain it carefully.

"First, the petrified magic weapon was deliberately encrypted by me, don't believe it."

He tossed the staff to Ladia, who immediately tried to reach into the mana to observe.

"Second, I've added a 'Salendel Ring Combination Lock' to the Petrification itself, and the code has six turns, with a hundred alternate spell keys for each turn."

This ring spell combination lock is specially designed to lock a constant spell effect, so as not to be snooped on by the opponent, and the spell effect is used to reverse the spell structure.

The good thing is that the effect is good, and the bad thing is that it greatly increases the complexity of the spell and greatly increases the difficulty of casting.

Lydia was observing the staff, not reacting.

Hal was shocked: "One hundred in six circles, that's ten billion possibilities, so how many star spells is your petrification technique?" ”

"With the addition of the Ring Spell Lock, it reaches 21 stars, but after being simplified by the staff, the casting difficulty is 5 stars."

Hal subconsciously asked, "How is it simplified?" ”

Rosen smiled: "I used some mathematical skills and original refining knowledge, but in short, it was very complicated. ”

Halton felt a headache, because Rosen's mathematical skills must have been extremely complex, extremely abstract, and extremely obscure, and then a thought suddenly occurred in his head.

"I seem to be being thrown off by the times!"

As soon as the thought came to mind, Lydia finally gave up exploring the petrified staff, and after she withdrew her mana, her body was planted straight forward.

Lawson hurriedly held it with the mage's hand.

Hal hurriedly asked, "Lydia, what's wrong, is the staff structure too complicated?" ”

Lydia slowed down for a moment before she came to her senses.

"No, it's not too complicated, it's all fog, all kinds of fog, and I can't tell the direction at all."

She handed the staff to Hal, "See for yourself." ”

Hal learned to be obedient and sat directly on the ground to check.

A few minutes later, he also withdrew, raising his hand to cover his forehead.

"Rosen, this must be your original spell lock, right?"

"I didn't do it alone, I created it with my wife."

As he spoke, his thoughts moved, and many long black wooden boxes flew out of the carriage next to him, and at the same time shouted loudly to the 280 civilian mages on the scene.

"Petrified Staffs are limited in number, one for every four people, and they are used on a rotational basis. According to the method I just released, I made the manor on this map. ”

'Brush~~'

More than a dozen paintings flew out of the carriage and were posted on the high wall built by Rosen, which was the resort manor designed by Rosen.

The civilian mages couldn't hold back for a long time, so they worked in groups of four and began to work together to build the manor.

While they were busy, Rosen came to the two friends.

Lydia asked softly, "Lawson, are you going to hire these civilian mages to help you build a town?" ”

"Yes."

"It's a good idea, but it should be a lot of commissions, right?" ”

Rosen smiled slightly: "Don't worry, it's enough."

He's doing a good business with Candela.

As far as he knew, Candela bought the Moon Maiden and hung it in her bedroom for five days, and then auctioned it off in the East.

As a result, the Moon Maiden was again accepted by the Duke of Storm at a high price in the Golden Hall.

In short, he has a lot of money now.

Ladia asked, "Then the Northern Fortress was also built with petrification?"

Rosen nodded: "Yes, I plan to build at least ten floors, 50 meters high, 30 meters thick, hundreds of miles long, and directly build on the highest part of the Falling Snow Mountain Range, connecting them into one and forming a cliff!" ”

Hal was a little dizzy when he heard this: "Are you an anti-dragon?" ”

Ladia's eyes lit up: "If that's the case, then it shouldn't be called a fortress, it should be called the Great Wall!" ”

"The Great Wall. Nice name. ”

After that, Rosen supervised by his side for more than an hour, answering the questions of the civilian mages at any time.

The mages he selected were all very smart, and they quickly understood the use of the petrified staff, and the progress of the manor gradually accelerated.

Depending on the situation, it will take a maximum of three hours for the estate to be completed.

Lawson looked at it for a while, and said to Lydia and Hal: "You help me supervise it, it doesn't matter if the manor is good or bad, the point is to let everyone get familiar with the usage safely." ”

Hal glared: "Hey~ You, the mayor of the town, are going to slip away?" ”

Rosen sighed lightly, "You also saw the clay potion just now. If that kind of potion can be popularized, then ordinary people can also participate in the creation of petrochemical buildings, and there will be enough manpower. ”

On the side, Lydia immediately understood, and there was sympathy in her eyes.

"So, you're going to find that crazy woman?"

Rosen sighed again: "Blame me for thinking about making money at the beginning, and as a result. Hey~~~"

Hal walked over and patted Rosen on the shoulder: "I understand, you can go at ease, this place will be left to us." ”

So, Rosen left five Silver Moon Ranger to help, and he took the other five Ranger and rushed to Vivien's Lily Manor in a carriage.
