Elemental pool technology was actually an energy supply device in the early Arcane Empire era, and since the advent of the Mithic Nucleus, elemental pool technology has gradually been transformed into civilian use.

It uses the element channel technology, through the principle of element siphon to pour the energy of the four major elemental planes into the element pool, the element pool technology is mature, although the energy efficiency is not high, but there is no need to worry about depletion, as long as the element pool is not damaged, it can run for thousands of years without damage.

Many of the remnants of the Arcane Empire's era have been able to function for thousands of years, in large part because of the constant energy provided by the elemental pool.

Hathaway built the elemental pool on the third basement floor, which is the energy center of the wizard tower, through the energy channel, you can complete the transmission of magic power, and transmit the energy in the elemental pool to the entire wizard tower, and the magic crystal is the most cost-effective material for making energy channels.

In fact, the ancient arcanists cultivated crystal beasts in a cheap way to obtain a large number of magic energy crystals, which is incomparable to the current wizards, knowing that the cost of arranging the entire wizard tower with magic energy crystals is not something that anyone can afford.

The Wizard's Tower has three basement floors.

Hathaway had created a circular pool twenty meters in diameter in the Wizard's Tower, located in the middle of the Wizard's Tower, and the surrounding ground was paved with white marble blocks, which had been magically treated, durable, and insulated.

The depth of the pool is 1.5 meters, and the whole body is made of marble, and after the stacking is completed, all the marbles are connected into a whole using fossil mud, and then solidified by turning mud into stone. There is also a silver coating on the surface of the marble.

Thorium is a substitute for Mithril, close in nature to Mithril, but much less effective, and the entire pool is plated with a layer of Thorthril. Next, Hathaway will need to use Mithril to engrave an oversized Shaped Circle into this pool.

This process alone consumes a lot of magic materials, although the value of the silver is not as good as the Mithril, but it is also worth a lot, plated with a layer of two hundred catties of the silver that is consumed, worth 200,000 gold nar, plus the Mithril engraved with the rune array, it is not that the local tyrant really can't afford it.

Next, various magic materials need to be added to this elemental pool, and Arcane Dust and Astral Dust need to be integrated into it to reduce the consumption of energy conversion. The basic structure of the elemental pool is not completed until these materials are perfectly integrated into the elemental pool.

Naturally, Hathaway would not have done this alone, as everyone else in the Wizarding Tower, including Suren, was involved, and it took them three days to complete the construction of this elemental pool.

After completing the elemental pool, the work is only half done, and the next step is to engrave four rune circles that connect the four elemental planes.

Hathaway took out a silver-white carving knife and carefully engraved runes in the four directions of the elemental pool, east, west, north and south, the elemental extraction and transmission circle is very complicated, and a little mistake will fail in the engraving, and it needs to be re-engraved, Hathaway summoned a ball of elemental fire after the engraving was completed? Then use the elemental fire to melt a piece of Mithril and use the hand of the wizard? Strands of melted Mithril are incorporated into the engraved rune array.

The whole process can only be made by Hathaway? Who let Zhenbei City only think she is an alchemy master. After the production was completed, Hathaway was in the center of the elemental pool? A platform of about one meter was built, and a complex rune array was engraved on the platform? In the center of the rune array? A diamond the size of an egg is incorporated into it.

Next, do you need four magic gems that replace the four elements of earth, fire, feng shui? Ruby, Sapphire, Emerald, Topaz, four magic gems of equal quality and uniform size are integrated into the four corners of the Elemental Pool.

As the gems were fused, the entire elemental pool vibrated slightly? Then a trace of strange energy appeared in the elemental pool. Meanwhile? Hathaway, Karina, Alex, and Grace immediately stepped forward and stood on the four elemental rune arrays of earth, fire, feng shui, and earth.

A powerful wave of elemental energy appeared around them, and these elemental energies wrapped the four of them in an orderly manner? Lift their bodies directly into the air.

A melodious and tactful Nether language sounded, this is a spell used to communicate the four elemental planes? As the sound sounded, generations of silver elemental energy rose, and four rune arrays with complex structures emerged from the four people, and then the space of the entire underground three layers of the wizard tower began to vibrate, and in the next second, four spatial cracks appeared on the rune array next to the four people.

Looking through the distorted spatial rift, you can see that behind the spatial rift are the blue and deep sea, the endless sky, the thick and solid earth, and the flame world that burns the sky. These four rifts are connected to the four elemental planes. As soon as Pu appeared, an abundance of elemental energy appeared in the four rune arrays, followed by four elemental energies injected into the platform in the middle of the elemental pool at the same time.

After the strange fusion of the four elemental energies of earth, fire, and feng shui, a stream of azure spring water flowed down from the platform, which was the elemental energy condensed into liquid.

With the appearance of the elemental water, the four people who cast the spell breathed a sigh of relief, as the elemental energy stabilized, the four elemental channels slowly disappeared, but the elemental energy still appeared endlessly and fused with the elemental water of the city, appearing in the elemental pool.

The Elemental Pool was successfully constructed, and at the same time, the Elemental Water in the Elemental Pool began to continue, and the concentration of elements in the entire three underground floors began to increase rapidly, but in just ten minutes, the concentration of elemental energy here increased several times.

This elemental pool made by Hathaway can hold two million degrees of energy, which can sustain the consumption of the entire elemental pool, and can also maintain the daily consumption of a large Golem army.

Of course, the cost of such an elemental pool is not low, and the cost of materials alone is more than one million gold nar.

The existence of the elemental pool transforms the entire wizard tower into an active place for the elements, and within the range of the wizard tower, all spellcasters will have a faster mana recovery rate, higher meditation efficiency, lower spell casting difficulty, and lower spell consumption.

[Elemental Pool (Large): Current Status: Charging, Current Energy: 100,000/2,000,000, Change Environment, Elemental Land, Cast Difficulty -20%, Cast Cost -20%, Mana Recovery +50%, Meditation Efficiency +25%,]

The elemental pool will change this area into the elemental land, and there will be many benefits to living in this environment, different environments will promote the evolution of organisms in different directions, according to the books and materials left by some arcanists, some of the floating cities that have entered the astral plane, because they have lived in the astral realm for a long time, the humans in the floating city have lived in the energetic astral realm for a long time, and have evolved a human subspecies, astral humans.

This kind of astral human has a longer lifespan than ordinary humans, and there are good talent astral humans who will awaken some psychic talents, or master some spell-like energy. These people are naturally psionic and can easily become wizards.

Of course, there will be some problems in living in this environment for a long time, such as after appearing in some areas where elemental energy is scarce, these astral humans will not adapt to the situation, just like a fish leaving the water, although it will not be life-threatening, but the spell casting ability is basically abolished, and in severe cases, there will be symptoms of demon addiction.

Of course, if you get used to it for a while, these problems will disappear, so the astral humans don't like to enter the material plane.

Although the elemental land is full of elemental energy, this will not happen, after all, the concentration of elemental energy is incomparable with the astral boundary, and because there is no rule bound by the material realm in the astral realm, the human soul can have deeper contact with this energy, in fact, the astral human beings evolved from the soul rather than from the body.

Once the Elemental Pool was built, construction began on other areas of the Wizard's Tower, including the Treasure Room, Prison, Meeting Room, Guest Room, Library, Bedroom, Laboratory, Meditation Room, Console, Control Center, Rune Barrier, Training Ground, Warehouse, War Room, Golem Legion, and Eco.

Many facilities need to be built, among which areas such as living rooms, guest rooms, bedrooms, and libraries are built quickly, but some areas are much more difficult to build, like an ecological garden, Suren plans to learn how to build a secret realm, and build one of the floors of the wizard tower into an ecological garden.

This ecological park will use space folding technology and space expansion technology, which can expand the wizard tower on a floor that was originally only more than 2,000 square meters by more than ten or even a hundred times, and then use space folding technology to place this ecological park in the wizard tower.

Space folding technology and space expansion technology, Hathaway is not very proficient, so he is not directly used in the wizard tower, once this spell has a problem, the result is very serious, Su Lun does not want his newly built wizard to directly break or deviate.

Only after becoming proficient will Suren use this technique in the Wizard Tower, which has an ecological garden, and can conduct many special experiments. In addition to the ecological garden, the laboratory and meditation room in the wizard's tower are also important.

These two places need to be isolated with rune arrays, whether it is experiments or meditations, it is taboo to disturb, once there is a problem, the consequences are also serious, and the remaining ones such as treasure vaults and prisons also need strict protection, and the construction of the entire wizard tower is progressing slowly.

Such a huge wizard tower, ten floors and one hundred and twenty meters, has an area of 30,000 square meters, it takes a lot of time to rely on just four wizards, and it is not a small project to lay the energy channel of the entire wizard tower.
