The element pool technology is actually an energy supply device in the early days of the arcane empire. Since the emergence of the miser energy core, the element pool technology has gradually been transformed into civil use.

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

In many relics of the age of the arcane Empire, those magic energy constructs can still operate normally after thousands of years. A large part of the reason is that the element pool continues to provide energy.

Hathaway built the element pool on the third floor underground, which is the energy center of the wizard tower. Through the energy channel, she can complete the magic transmission and transmit the energy in the element pool to the whole wizard tower. The magic energy crystal is the most cost-effective material for making the energy channel.

In fact, the method of raising crystal beasts by ancient magicians can obtain a large number of magic energy crystals in a cheap way, which is unmatched by wizards now. You know, no one can afford to arrange the whole wizard tower with magic energy crystals.

The wizard tower has three floors underground.

Hathaway has made a round pool with a diameter of 20 meters in the wizard tower. The pool is located in the center of the wizard tower. The surrounding ground is paved with white marble blocks. These marble have been treated by magic, hard and durable, and have good isolation effect.

The depth of the pool is 1.5m. The whole body is stacked with marble. After the stacking is completed, fossils are used as mud to connect all the marble into a whole, and then the mud is used to solidify the marble. There is also a silver coating on the surface of marble.

Se silver is a substitute for MI silver. It is similar to MI silver in nature, but the effect is much worse. The whole pool is coated with Se silver. Next, Hathaway needs to use secret silver to engrave a super large shaped energy array in the pool.

Just this process consumes a lot of magic materials. Although the value of silver is not as good as secret silver, it is also valuable. Plating a full layer of silver, which costs 200 kg, is worth 200000 jinnars. Coupled with the secret silver engraved with Rune array, it is not that local tyrants really can't afford it.

Next, you need to add various magic materials to this element pool. Arcane dust and star dust need to be integrated into it to reduce the consumption in energy conversion. After these materials are perfectly integrated into the element pool, the basic structure of the element pool is completed.

Naturally, this project will not be made by Hathaway alone. Other people of the wizard tower, including Su Lun, participated in it. They spent three days together to complete the construction of this element pool.

After completing the element pool, the work is only half completed. Next, we need to engrave four symbol matrix connecting the four element planes.

Hathaway took out a silver carving knife and carefully engraved runes on the four directions of the East, West, North and south of the element pool. The element extraction transmission array is very complex. If there is a mistake, the engraving will fail and need to be engraved again. After the engraving, Hathaway summoned a group of element fire, then manipulated the element fire to melt a piece of secret silver, and then used the hand of a wizard, Melt the melted secret silver into the engraved Rune array.

Only Hathaway can make the whole process. Who makes her the only alchemist in the north town. After the production, Hathaway built a one meter platform in the center of the element pool, and engraved a complex Rune array on the platform. In the center of the rune array, a diamond the size of an egg was integrated into it.

Then there are four magic stones, ruby, sapphire, emerald, and topaz, which are the four elements that replace the geomancy and Fengshui respectively. Four pieces of magic jewels with the same quality and the same size are integrated into four corners of the element pool.

With the integration of gemstones, the whole element pool vibrated slightly, and then a trace of strange energy appeared in the element pool. At the same time, Hathaway, Karina, Alex and grace immediately came forward and stood on the four element Rune matrix of earth fire and geomantic omen.

A powerful elemental energy appeared around them. These elemental energy wrapped the four people in an orderly manner and lifted their bodies directly in the air.

The melodious and graceful Nasser language sounded. This is a spell used to communicate the four element planes. With the sound, the silver element energy rose from generation to generation, and four complex Rune arrays emerged from the four people. Then the space on the third floor of the whole wizard tower began to vibrate, and four space cracks appeared on the rune array next to the four people.

Looking through the twisted space crack, you can see that behind the space crack are the blue and deep sea, the endless sky, the thick and solid earth, and the flame world burning to the sky. The four fractures are connected with the four element planes respectively. As soon as PU appeared, abundant element energy appeared in the four Rune arrays, and then the four element energies were injected into the platform in the middle of the element pool at the same time.

After the strange fusion of the four element energies of earth fire and geomantic omen, a blue spring flows down from the platform, which is the element energy condensed into liquid.

With the appearance of elemental water, the four casters were relieved. As the elemental energy became stable, the four elemental channels slowly disappeared, but the elemental energy still appeared in an endless stream, and the water of the fusion city elements appeared in the elemental pool.

The construction of the element pool was successful. At the same time, the element water in the element pool began to continue, and the element concentration in the whole three underground floors began to increase rapidly. However, in more than ten minutes, the element energy concentration here increased several times.

The element pool made by Hathaway can hold 2 million degrees of energy, can maintain the consumption of the whole element pool, and can also maintain the daily consumption of a large mage Legion.

Of course, the cost of such an element pool is not low. The price of materials alone is more than one million ginals.

The existence of the element pool transforms the whole wizard tower into a place where elements are active. Within the scope of the wizard tower, the magic recovery speed of all casters will be accelerated, the meditation efficiency will be improved, the difficulty of spell casting will be reduced, and the spell consumption will be reduced.

[element pool (large): current status: charging, current energy: 102 million, changing the environment, the place of elements, casting difficulty - 20%, casting cost - 20%, magic recovery + 50%, meditation efficiency + 25%,]

The element pool will change this area into a land of elements. Living in this environment will have many benefits. Different environments will promote organisms to evolve in different directions. According to the books and data left by some arcane masters, some floating cities entering the star world, because people living in the star world for a long time, and people living in the floating city live in the energetic star world for a long time, Evolved a human subspecies, astral humans.

Such astral humans live longer than ordinary humans, and those with good talents will awaken some spiritual talents or master some spell like energy. These people are naturally psychics and can easily become wizards.

Of course, there will be some problems in living in this environment for a long time. For example, after appearing in some areas where elements and energy are scarce, these astral humans will not adapt. It is like a fish leaving the water. Although there will be no life danger, the spell casting ability is basically disabled, and in severe cases, there will be magic addiction symptoms.

Of course, if you adapt to it for a period of time, these problems will disappear, so astral humans do not like to enter the physical plane.

Although the land of elements has abundant energy, this will not happen. After all, the energy concentration of elements is incomparable with that of the star world. Moreover, because there are no rules of the material world in the star world, the human soul can be more deeply exposed to this energy. In fact, the human beings in the star world evolved from the soul rather than from the body.

After the completion of the element pool, other areas inside the wizard tower began to be built, including treasure room, prison, reception hall, guest room, library, bedroom, laboratory, meditation room, console, control center, Rune boundary, training ground, warehouse, combat readiness Office, combat room, magic image Legion and ecological park.

Many facilities need to be built, such as reception hall, guest room, bedroom and library. However, the construction of some areas is much more difficult, such as ecological park. Su Lun plans to learn the construction method of secret place and build one floor of wizard tower into an ecological park.

The ecological park will use space folding technology and space expansion technology, which can expand the wizard tower on the first floor of more than 2000 square meters by more than ten times or even a hundred times, and then use space folding technology to place the ecological park in the wizard tower.

Hathaway didn't master the Space folding technology and space expansion technology very well, so she didn't use it directly in the wizard tower. Once there was a problem with this spell, the result would be very serious. Suellen didn't want his newly built wizard to break or deflect directly.

Only after becoming proficient will sulun use this technology in the wizard tower. After the wizard tower has an ecological park, it can carry out many special experiments. In addition to the Eco Park, the laboratory in the wizard tower and the meditation room are also very important.

These two places need to be isolated by Rune array. It is taboo to disturb whether it is experiment or meditation. Once there is a problem, the consequences are also very serious. The rest, such as treasure houses and prisons, also need strict protection. The construction progress inside the whole wizard tower is slow.

Such a huge wizard tower has ten floors and 120 meters, with an area of 30000 square meters. It takes a lot of time to rely on only four wizards. The laying of energy channels in the whole wizard tower is not a small project.
