Suren and Hathaway soon searched the area, eventually finding six enchanted weapons, three pieces of magic jewelry, one ring, a bracelet, and a necklace.

As for the space bag, there is no one, thousands of years of time is enough to make the enchantment on the space bag invalid, and the items inside can fall out if they are lucky, and they will be destroyed together when the space collapses if they are unlucky.

The material of the three pieces of magic jewelry is not bad, if it weren't for this, the magic aura on it would have dissipated long ago. But to keep it for so long shows that these pieces of jewelry are not bad.

"Suren, look what I've found!" Hathaway shouted in surprise.

Su Lun put away his things and hurriedly looked over, only to see Hathaway holding a crystal ball and waving at Su Lun with excitement on her face.

"What is this?" Suren looked at Hathaway with some strange eyes.

"The control center of the secret realm, this is the control center of this secret realm!" Hathaway said loudly.

Su Lun was overjoyed, and he didn't care about picking up any more rags, so he ran over in three steps and two steps.

"This is the control center of the secret realm?" Su Lun asked as he took the crystal ball handed over by Hathaway, this crystal ball is not much different from an ordinary crystal ball, but there is still some strange energy in the crystal ball.

"This is a control center made by the arcanists, and after activation, you can control the entire secret realm, but the energy here has been interrupted for a long time, and you need to reconnect the energy to activate it. Hathaway explained.

"Where is the power source of the secret realm?"

"The source of energy in this secret realm should be the elemental pool, and this important facility should be placed in the safest place, and if nothing else, it should be in this castle. ”

"We've searched all over this and haven't found the elemental pool, so there's only the basement!" The two didn't delay any longer, and directly began to look for the passage to the basement.

After a long passage, the two of them finally found the room leading to the basement in an inconspicuous room, and through a long passage, they came to the basement in the castle, which had not been damaged too much, and the crystal magic lamps on the walls still emitted a faint light.

Some of the damaged Constructed Golems fell to the side, and in the middle of this basement, a pool of water with a diameter of ten meters appeared in front of the two of them, this one was built of marble, and many complex rune arrays were engraved on the marble, and the perimeter of the pool was connected to the energy channels made of magic energy crystals, which transmitted the energy in the pool to all parts of the secret realm.

It's just that the energy in this elemental pool is close to drying up, and the original marble is covered with a large number of cracks, and several runes have been damaged. Overall, the elemental pool is still seventy percent complete. Some elemental energy is also leaked out of the energy pool.

Although it has been damaged, this elemental pool still has some working capacity, and it can draw energy from the four elemental planes, but it has become very inefficient, which is why this secret realm can last for thousands of years.

Now that the Elemental Pool's energy is about to run out, Suren will need to restore the Elemental Pool if he wants to regain control of this secret realm.

"Hathaway, can this elemental pool still be repaired?" asked Suren with a frown.

"I need to check it out. Hathaway said with a solemn expression.

The construction of a complete elemental pool requires at least a fourth-order wizard to build, and Hathaway is only one step away from a fourth-order wizard, but the elemental pool in front of her is still seventy percent complete, and the difficulty of repairing it should not be so great.

The Elemental Pool is also the energy source of the Wizard Tower, and the Wizard Tower with the Elemental Pool is the real Wizard Tower, which uses the link of the four elemental planes, and then draws elemental energy from the four elemental planes, and then gathers into elemental water in the elemental pool.

Elemental water is also the most peaceful state of elemental energy, and it is often used in alchemy experiments, and it costs about 500,000 to 1 million jinnars to build a complete elemental pool, and in addition to the basic high-quality marble, four high-quality magic gems are needed, one each for ruby, sapphire, emerald, and topaz, which are used to link the four elemental planes.

If the quality of the gem is not enough, it will burst when passing through elemental energy, in addition to these, the construction of the elemental pool requires a large amount of silver and gold, as well as a small amount of Mithril, a large block of high-quality mana crystals.

High-quality large pieces of magic crystals have very good magic conductivity, and the loss in the process of conducting magic energy is very low, and the same mineral is very rich in the material world, and even wizards have mastered the technology of artificial magic crystals, because magic crystals are the most cost-effective, so magic crystals are used in large quantities.

The marble surface of the Elemental Pool needs to be coated with a large amount of silver, and silver, gold, Arcane Dust, Arcane, and Star Iron are fused in proportion to engrave the rune array. The rune circle in the elemental pool is a large concentrating circle, in addition to four rune circles that are used to link the four elemental planes.

Hathaway didn't have so many materials in her hands, but fortunately, she had a lot of them in Suren's storage space, and some of the materials that she didn't have needed needed to be dismantled from those scrapped steel golems. It is then smelted and made on site.

Hathaway is very skilled in refining and fusing materials. Summoning a ball of psionic fire, then using the wizard's hand to melt all the metals, and finally smelting them together, resulting in a silver solution with gold threads.

Suren repaired the damaged marble when Heather ran out of smelted materials, and Hathaway began to manipulate the wizard's hand, using a carving knife to repair the broken runes on the elemental pool.

Strands of silver were extracted from the mass of molten metal, and then carefully engraved onto the marble, the rune array of the elemental pool required a very high degree of precision, according to the previous life, it was accurate to the micron, and this level of intelligence relied on mental power to act.

Hathaway's movements were very slow, not daring to have the slightest carelessness, Su Lun had long held her breath, for fear that the movement would be too big to alarm her, there were more than three hundred runes on this elemental pool, and there were more than ninety runes that needed to be repaired, and all the runes needed to be engraved with an accuracy of microns.

One by one, the runes Hathaway was repaired, and the molten metal was constantly filled, and it took several hours, the sky was already dark, and Hathaway finally repaired the last rune, and as the rune array was repaired, a spiritual light flashed, and there was no trace of leakage in the elemental pool that was still leaking.

In addition to these, the original four magic gems used to link the four elemental planes also need to be replaced, after thousands of years of operation, these gems have not been maintained, and the link channel has become very unstable, and there is a possibility of interruption at any time.

Taking out four red, yellow, blue, and green gems of the same size and similar quality from the storage bag, Hathaway began to carve them with a carving knife, which required the carving of symbols representing the four elements, which seemed much easier to carve than the elemental pool.

Soon the four magic gems were carved into diamond shapes, each with a rune symbol engraved in it, and Hathaway carefully replaced the original four magic gems in the elemental pool, and the four new magic gems successfully integrated into the four directions of the elemental pool.

"Weng!"

With a soft sound, the entire space seemed to shake slightly, and then four huge streams of energy appeared in the basement, and a trace of strange energy poured into the elemental pool. The elemental energy converged in the elemental pool to form a pale blue elemental water, and soon a thin layer of spring water appeared in the elemental pool that had already bottomed out.

With the advent of Elemental Water, the concentration of elements in the basement has become very rich, and the establishment of the Elemental Pool is not only an important energy source for the Secret Realm or the Wizard Tower, but also the Elemental Pool will also make great changes to the surrounding environment, the most obvious is the increase in the concentration of Elementals.

The Elemental Pool can transform the area into an Elemental Active Zone, where the Wizards' cast speed and mana regeneration are enhanced, as well as the meditation effect is increased, which is very important for wizards.

At the same time, the Elemental Richness can also grow various demonic plants, and the rich elemental energy here is more suitable for their growth.

According to the division of wizards, the concentration of elements is divided into several levels, and the highest concentration of elements is called the land of elements, the elemental energy in this place is close to liquefaction, and the body will be slowly transformed by the elemental energy if you live in this place for a long time, and eventually even evolve some spell-like abilities.

The second level is the Elemental Active Place, which is mostly transformed by wizards, and can basically be transformed into a piece with an elemental pool. The next third level is the land of abundant elements, most of these places are naturally formed with abundant element concentrations, and generally many demonic plants and demonic beasts will grow in these places.

The fourth level is the normal concentration of elements, most of the material planes are in this state, the fifth level is the place of scarcity of elements, this kind of environment is not much in the main material realm, where the effect of meditation recovery will be slowed down, and the seventh is called the area of dead demons.

In this area, the elemental energy is extremely scarce, and the wizard's spell casting becomes very difficult, and the difficulty of casting spells directly increases, and the recovery becomes extremely slow. Most of these areas are caused by spells that have severely damaged the material realm or serious experimental accidents. The most famous place is the Desert of Despair.

There are also some environments known as the Forbidden Demon Realm, which are almost completely devoid of any elemental energy, and the difficulty of casting spells increases by at least two rings, and generally middle and low-level wizards will directly lose their ability to cast spells after coming here.
