"40 standard units of dark crystals, the conversion rate is barely passing, and the formation of the two floors above ground is quite passable, but the two floors underground have to be rebuilt. ”

A group of elven mages and an elven ranger walked straight past the gate of Sunset Town, skimmed several floors of the building, and landed directly on the black central square.

As soon as he landed, a very young-looking elf mage ran out of the elven mage, and after a few quick steps, he reached the foundation of the mage tower, touched it a few times, muttered a few words in a low voice, and then turned his head to Kelreth who had already followed.

"Why!"

The old profiteer, who didn't know where to come from, asked with a surprised expression.

He has been very carefully inspected the foundation blank of this four-story mage tower in the past few days, don't look at his usual behavior as a profiteer, of course, he is actually a profiteer, but the essence of his six-ring mage has not declined in so many years of stagnation, and even because of the abandonment of the high-level, it itself has developed a lot in many other magic fields, among which the casting field of the mage tower, because there are too many aspects that need to be designed, he is only roughly involved, but as a magic merchant in Dalaran, there are actually not a few mage towers built by his hands, and he is not a layman who knows nothing。

The two-storey above-ground and two-storey underground mage tower structure in front of you, although it is very rough, is a popular standard structure of the mage tower in Dalaran, and almost more than forty percent of the Dalaran private mage tower in the past hundred years is the basic layer built according to this structure.

"The Mage Tower is not a building block!" the young elven mage glanced at Old Bolen, a hint of mockery flashed across his face, and an old-fashioned expression appeared on his immature face.

"The most correct use of the ground floor is to build a different space laboratory, a negative energy pool and a magic energy laboratory, but one or two layers must be left empty above these layers, as an isolation layer, the isolation layer does not need such a thick crystalline structure, and the space is too small. ”

"Where's the elemental pool?" asked Kyrreth who was standing aside this time.

"Three options, one floor above ground, one floor in the median, and one floor at the top. ”

Knocking on the black crystalline wall, the elven mage replied casually.

"The top floor?"

Frowning at each other, Kyrreth repeated all his thoughts.

"Yes, actually, the top floor is the most suitable place to place the elemental pool!"

"Indiscriminate Mixed Energy Conversion Circulatory System?!"

Looking up at the sun in mid-air, the mid-level mage turned his head and looked at the elven mage in a daze.

"Oh! you know that!"

Stopping the movement in his hand, the elven mage turned his head to look at Kelreth in some surprise, this kind of advanced magic theory, at present, Dalaran, or the human mage of the Dalaran people has no relevant information.

In Dalaran, the mage towers that use the undifferentiated hybrid energy conversion circulation system are all built by the high elves, most of them are high-level mage towers and those legendary towers, of course, the legendary mage towers of human archmages, the high elves are only responsible for the energy core, after all, under the condition of conditions, no mage is willing to give his mage full power to others, or build it by another race.

Therefore, under normal circumstances, the average Dalaran mage would not have known about the existence of this system.

"I'm a full member of the Pattern Explorers"

Kyrreth pursed his lips and said calmly.

As the energy core of the mage tower, the element pool is an indispensable structure of every mage tower, and its role is to absorb the free energy around it for storage and provide energy for the operation of the entire mage tower.

But the absorption of each kind of energy, Storage to utilization is an extremely complex program, without a certain energy thoroughly studied, hastily collected and utilized, the consequence can only be a great effort to create a very unstable elemental bomb, and human mages after so many years of development, there is only one kind of energy that can really be completely controlled, that is, the energy of the arcane, in addition to this, the progress of fire, frost and other energies is far from reaching the corresponding standards, so the element pool owned by the mage tower of the human mage is generally a pure arcane energy pool, in terms of energy storage and transformation, although it is not very limited, but it can only be said to be reluctant。

The existence of the undifferentiated mixed energy conversion circulation system is the perfect performance of the high elves in the field of magic to beat humans, and the elemental pool built on the basis of this system is the real elemental pool, which can absorb almost all the energy and carry out transformation and storage.

However, the reason why Kelrith knew about the existence of this system was because the old mage had given a very detailed explanation of this system in a certain class, and even in order to let the intermediate mage understand it more clearly, he also built a miniature indiscriminate hybrid energy conversion circulation system on the spot, disassembled and formed several times, at that time Kelrith was still a beginner mage, and he was still in a state of ignorance of magic patterns. However, Kyris also knew that even if he said that his mentor told him, the other party might not believe it, and the annoyed mid-level mage directly revealed his identity as a demon pattern explorer.

"What!"

This time, not only did the young elf look at Kelreth in shock, but there was also a lot of commotion in the elven mage team, except for Anlidalense, a high-level mage, the other elves all turned their heads to stare at Kelrith, as if they saw a wild cat, and suddenly found that it was actually a pure-blooded saber-toothed tiger.

"Anway Darans!"

Dazerian, who had not moved much since he landed, stared at Kelris for a while, then turned his head and gritted his teeth to look at the high-level mage.

"Hey, hey!" the thief smiled, and Anlidalance began to play with his wand.

"Mage, don't you know that as a full member of the Pattern Explorer, you are eligible to apply for a low-level mage tower from the Demon Pattern Explorer Headquarters?"

The corners of Dazerien's mouth twitched for a long time before he looked at the expressionless Kyris and said helplessly.

"I don't know..."

Also the corners of his eyes jumped a little, Kyris turned his head to look at the profiteer on the side, feeling the inquiring gaze of the middle-level mage, Old Bolun nodded angrily, there are not many members of the Demon Pattern Explorer even among the high elves, let alone among the human mages, almost all of them are high-level or even legendary, and the benefits of a low-level mage tower are not too much.

But Kyris can become a full member at the middle level, which reflects the talent of Kyrryth Magic Pattern on the side, and also makes Old Bolun more interested in his true identity, you know, the review and arbitration of the official members are all high elves, and legend has it that the audit of humans is much stricter than that of elves, although Kyris is a half-elf, but it is not much better.

"Hmph! It's just a low-level mage tower! Since I said that there is a reward, naturally I won't pull the calf!"

The high-level mage who had been playing with his wand for a long time finally stopped, nodded at the young elf at the beginning, and the ring on the other party's hand flashed, and a palm-sized polyhedral gem appeared on his hand, and one by one the magic patterns turned into entities and connected into several long chains, wrapped around the surface of the polyhedral gem.

"Smart Tower Core!"

Looking at the gem in the elf's hand, the old profiteer's eyes widened and he couldn't help but shout.
