Theoretically, the minimum number of floors of a magic tower is three, because the number of core magic circles that build the complete circuit of the magic tower is exactly three.

"Circle: Song of the Elements" is the most powerful auxiliary bonus circle, which can effectively increase the mage's affinity for the elements of the system, and has a certain bonus to the mage's spell control, and the bonus amplitude gradually increases depending on the number of layers of the magic tower.

The "Magic Circle: Energy Furnace" is the source of energy for the operation of the magic tower, which can not only extract the amount of mana condensed in the magic crystal, but also continuously extract and refine the surrounding free energy, store and use it. A working "energy furnace" can ensure the daily supply of magic power to the magic tower, and cope with a certain degree of unexpected situations.

The "Circle Domain Scepter" is the core of the three cores, and it is the true embodiment of the power of a magic tower. It can spread the power of the mage into the surrounding area, detecting, controlling, defending, and even directly launching powerful spells against incoming enemies.

A high-level or higher magician, relying on a magic tower, can even take on the spell defense task of an entire city by himself, while also providing a certain amount of fire support. Last year, Norman City was able to resist the attack of Innedir's elite army, relying on the strength of a magic tower that was not very complete, and the manipulator was only a student of the great wizard of Haji.

Of course, the three-story magic tower built on the three core magic circles is only the most introductory of the magic towers. Of course, the reason why the core magic circles are called cores is only because of their indispensable status, and the reason why the high-level magic towers can have a power and a broader field far beyond ordinary magic towers is that the difference lies in the rest of the main magic circles.

The structure of the core circle, after so many years of development, has tended to be mature and concise. There was little room for improvement, and Allegri only needed to choose the one that suited him from the existing structure diagram of the core circle and start drawing. At present, the most important thing for him is the choice and design of the remaining three main circles.

He was holding a charcoal pencil and a few pieces of parchment, scribbling something. A few magic books were scattered around, and Allegri sat on the grassy slope, pondering his next choice. This location overlooks the hot construction site not far away. The main body of the magic tower has protruded from the ground, increasing little by little, this is his magic tower, the six-story tower that will be built.

Not far in front of him, Herseus, in the form of a small burning man, was hovering in the air and pacing.

"How's the core circle chosen?" he asked, tilting his head.

"Okay, the 'Song of the Elements' naturally chose the flame-based 'Song of Fire', and the same goes for the 'Domain Scepter'," Allegri replied casually, "As for the 'Energy Furnace'. Didn't you suggest I choose that two-stroke energy furnace?"

"What two-stroke energy furnace?" Herseus blew his beard and glared, "It's a dual-circuit energy furnace, you see, this memory ability is far worse than that little girl in Afra." ”

"Cut, no matter how good it is, my student is not you," Allegri said with a frown, accustomed to this. "Teacher, I think this main circle is very good. Would I like one?"

"I'll take ......a look," Herseus flew over with a flash of fire.

Allegri hurriedly beckoned, "Hey, hey, teacher, take it easy, don't burn my book." ”

"I think your brain is burning," Herseus glanced at the book. He sneered, "Do you want to put this circle on your magic tower?"

"yes, what's wrong?" Allegri scratched his head, "'Dragon's Breath Cannon', it sounds pretty domineering." ”

"It's very domineering. Herseus snorted, "I'm afraid that before the half-cannon is fired, your 'energy furnace' will not be able to withstand the explosion first." ”

"Really?" Allegri wondered, "Isn't it true that I have a single attack circle to control this area?"

"Don't underestimate the core magic circle, the most basic thing can reflect the true quality of a magician, do you believe that I only need a 'domain scepter' to keep out an army of 100,000 people?" Herseus said proudly, "As for that 'Dragon's Breath Cannon', the energy consumed is not something that your dual-loop energy furnace can afford. ”

"The dual-circuit energy furnace won't work, so let's make a bigger one?" Allegri was still a little thief.

"The dual-circuit energy furnace is already the maximum I think you can accept," Herseus explained disdainfully, "Do you know how much magic crystals are needed to consume a daily 'energy furnace' with full strength?

Allegri stared, a little dazed.

"Therefore, it is easy to build a magic tower, and it is the most difficult thing to supply the magic crystals consumed by this magic tower," Herseus snorted, "I still dare to let you choose this based on the premise that you can get a large number of taps after the opening of the trade route." ”

"Well," Allegri sighed regretfully, turning the page on "Dragon's Breath Artillery", "and what do I do with what you mean?"

"Do you still have a bit of a decision to ask me about everything?" Herseus snorted, "and leave it up to you to decide, and it will be a test for you." ”

"Cut, is this a test?" Allegri flipped through the book, "It's a trifle." ”

In the sky, the sun slowly tilted, and Bai Ji led the little barbarians to climb to the top of the hill on the other side to play, and the dwarf Hoel did not know when he mixed with them.

Brooke was still at the side of the construction site and guided the work of the stonemasons, with a few stout dwarven craftsmen being the main force among them, and the progress was rapid. Cyrell and Dios didn't know what to talk about, but their expressions were not very relaxed, but Illo was nowhere to be found in the valley, and he was the most active one on weekdays.

"By the way, Teacher, the 'Plane Warehouse' should be required, right?" Allegri asked suddenly.

"No," Herseus shook his head repeatedly, "Even I don't have a specific method for setting up a pure 'plane warehouse', this pure space opening spell has long been lost. ”

"But every magic tower I've seen has a 'magic warehouse,'" Allegri frowned, "Teacher, isn't that so?"

"The 'Plane Warehouse' is not good, is there anything else, don't say more, you can think for yourself," Herseus walked around, he couldn't go too far from the range of the ring, "By the way, Allegri, do you hear what Onisha meant the other day?"

"You talk about private soldiers?"

Herseus said, "I guessed it, and I think she's very interesting to you." ”

"Phew," Allegri snorted, "isn't 'Violet' still your title, why don't you say he's interested in you?"

"The old man thinks so, but it's a pity that he has no heart......" Herseus stroked the flame's beard and sighed, "Do you think that Onisha is very scheming?"

Allegri thought for a moment and nodded.

"But in my opinion, these are nothing, the old man's scheming back then was much higher than hers. Herseus snorted, "How many legendary professionals were there in the Demon Legion of the Church of Light back then, and I talked and laughed with them......

"What do you mean?" Allegri wondered.

"This little girl, with a sense of hatred, has gone through a lot of hard work to rebuild the 'Fire Demon Knight', and what she is doing is just revenge. Because she also knew that if she wanted to recover her homeland, it was absolutely impossible to fight against the Church of Light, so she could only do her best to stab the Church of Light, and from this point of view, she was actually very sad......" Herseus sighed, as if he had some resonance in his heart, as if he remembered the past thousands of years ago.

"Later, with the opportunity of 'The Road of the Walker', under the encouragement of the old man's clever tongue, the road to restoration finally had a glimmer of light. But after that enthusiasm subsided, she had to think about these practical problems, and a powerful and deceitful fool like you was naturally the target of her to deal with casually. ”

"So I ...... It's a bit too much, isn't it?" Allegri argued.

"But stupid people also have the benefits of stupid people, if you don't say anything else, at least you have one advantage, and you are a good person," Herseus said slowly, "Even if you give you the army, will you usurp her position as the Grand Duke?"

"I don't have anything to do. Allegri had a bored expression of indifference to fame and fortune.

"That said, you wouldn't do that kind of thing," Herseus couldn't tell whether it was praise or sadness on his face, "The Duchy of Anlan is not known for its strong army, which is the real reason why it is so vast that it was annexed by the Church of Light. Onetsa's army, the strongest is the 'Fire Demon Knight', Onesha is putting hope in you......"

"I don't think it'......," Allegri shook his head.

"Don't underestimate yourself, don't live up to expectations," Herseus said bitterly, "As my student, you should be a little ambitious. It's time to think about your own strength, at least Dios is very eager to have an army of his own. ”

Allegri's brow furrowed, a thoughtful look on his face.

"The Church of Light, the Demon Legion, the Emperor of the North, the chaotic ......situation," Herseus gestured with a gesture of a speaker, "This magic tower is built here, and there are enemies on all sides, and you must have the strength to protect yourself." And that's not enough to just be a good person. ”

"By the way, teacher, you always say that I am a good person, but what about you?" Allegri looked at the old mage, "Then you were a good person back then?"

Herseus stopped, hovering above the flames, his expression quickly dimming.

"Back then, many people worshipped me as a god, and many more people regarded me as a devil...... However, no one seems to think that I am a good person. (To be continued......)
