Soon Suellen and Hathaway searched here and finally found six enchanted weapons and three magic jewelry with repair value, including a ring, a bracelet and a necklace.

As for the space bag, there is no one. Thousands of years is enough to invalidate the enchantment on the space bag. The items in the space bag can fall out with good luck. If bad luck, they will be destroyed together when the space collapses.

The materials of the three magic jewelry are quite good. If not, the magic light on them would have dissipated long ago. But it's good to keep these jewelry for so long.

"Suellen, look what I found!" just then Hathaway shouted in surprise.

Suellen put away her things and quickly looked over. Hathaway waved to Suellen with a crystal ball in her hand.

"What is this?" sullen looked at Hathaway strangely.

"The control center of the secret place, this is the control center of the secret place!" cried Hathaway.

Su Lun was overjoyed. He couldn't pick up any more junk. He ran over three steps and two steps.

"This is the control center of the secret place?" Su Lun asked after receiving the crystal ball from Hathaway. This crystal ball is not different from an ordinary crystal ball, but there are some strange energy in the crystal ball.

"This is the control center made by the arcane masters. After activation, it can control the whole secret place, but the energy here has been interrupted for a long time. If you want to activate it, you need to reconnect the energy," Hathaway explained.

"Where is the energy source of the secret place?"

"The energy source of this secret place should be the element pool. This important facility should be placed in the safest place. No accident should be in this castle."

"We've searched the above and haven't found the element pool, so there's only the basement!" without further delay, they directly began to look for the passage to the basement.

After spending some time, they finally found the room leading to the basement in an insignificant room. Through a long passage, they came to the basement in the castle. The basement was not greatly damaged, and the crystal magic lamp on the wall still emitted a faint light.

Some damaged magical figures fell aside. In the middle of the basement, a pool with a diameter of 10 meters appeared in front of the two people. The building was built with marble, on which many complex Rune arrays were engraved. The periphery of the pool was connected with energy channels made of magic crystal, These energy channels transmit the energy in the pool to all parts of the secret place.

However, the energy in this element pool has nearly dried up, the original marble wall is full of cracks, and several runes have been damaged. Overall, the integrity of this element pool is still 70%. Some elemental energy also leaks out of the energy pool.

Although it has been damaged, the element pool still has some working capacity. It can draw energy from the four element planes, but the efficiency becomes very low. This is why this secret place can last for thousands of years.

Now the energy of the element pool is about to run out. To regain control of this secret place, sulun needs to repair this element pool.

"Hathaway, can this element pool be repaired?" sullen asked with a frown.

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

The construction of a complete element pool requires at least a fourth-order wizard. Hathaway is only one step away from the fourth-order wizard, but the integrity of the element pool in front of her is still 70%, so it should not be so difficult to repair.

Yuansu pool is also the energy source of wizard tower. The wizard tower with element pool is the real wizard tower. It links the four element planes, then absorbs element energy from the four element planes, and then converges into element water in the element pool.

The elemental water is also the most peaceful state of elemental energy. Many times it will be used in the gold test. The construction of a complete element pool takes about five hundred thousand to one million Jin's cost. Besides the foundation of the best marble, it also requires four high-quality magic stones, ruby, sapphire, emerald and Topaz each. These gemstones are used to link the planes of the four elements.

If the quality of the gem is not enough, it will burst when passing through the element energy. In addition, the construction of the element pool requires a large amount of silver and gold, as well as a small amount of secret silver and high-quality large magic crystal.

High quality large magic crystal has very good magic guiding property, and the loss in the process of conducting magic energy is very low. Similarly, magic crystal is rich in the material world, and even wizards have mastered the technology of artificial magic crystal. Because magic crystal has the highest cost performance, magic crystal is widely used.

The marble surface of the element pool needs a large amount of silver coating, and silver, gold, Austrian law dust, Austrian steel and Star iron are fused in proportion to engrave the rune array. The rune matrix in the element pool is a large shaped energy array. In addition, there are four Rune matrices used to link the four element planes.

Hathaway doesn't have so many materials in her hand. Fortunately, sulun has brought a lot of materials in her storage space. Some materials that don't have need to be removed from those scrapped steel puppets. Then it is melted and made on site.

Hathaway is very skilled in refining fusion materials. Summon a psionic fire, then operate the wizard's hand to melt all these metals, finally melt them together, and finally get a silver solution with gold wire.

Suellen repaired the damaged marble when Heather had no smelting materials. Then Hathaway began to control the wizard's hand and repair the damaged Rune on the element pool with a carving knife.

A silver thread is extracted from the liquid metal, and then carefully engraved on the marble wall. The rune array of the element pool needs very high accuracy. According to previous generations, it is accurate to microns. This level of intelligence depends on mental force.

Hathaway's action was very slow and did not dare to be careless. Su Lun had long held her breath for fear that her action would disturb her. There were more than 300 runes on the element pool, and more than 90 runes needed to be repaired. All runes needed to be engraved with an accuracy of microns.

One by one, Hathaway repaired the runes, and the liquid metal continued to fill. It took several hours, and the sky was dark. Hathaway finally repaired the last rune. With the repair of the rune array, a flash of light flashed, and there was no leakage in the element pool that was still leaking.

In addition to these, the original four magic gemstones used to link the planes of the four elements also need to be replaced. After thousands of years of operation, these gemstones have not been maintained, and the link channel has become very unstable and may be interrupted at any time.

Four red, yellow, blue and green gemstones of the same size and similar quality were taken out from the storage bag. Hathaway began to carve with a carving knife. This gem needs to be carved with symbols representing the four elements. Compared with the element pool, the carving of these gemstones is much simpler.

Soon, the four magic gemstones were carved into diamonds, and each gem was engraved with a rune symbol. Hathaway carefully replaced the original four magic gemstones in the element pool, and the four new magic gemstones successfully integrated into the four directions of the element pool.

"Weng!"

With a light sound, the whole space seemed to vibrate slightly. Then four huge energy appeared in the basement, and a trace of strange energy poured into the element pool. The element energy gathered in the element pool to form a light blue element water. Soon, a thin layer of spring appeared in the element pool that had already bottomed out.

With the emergence of elemental water, the element concentration in the basement becomes very strong. The establishment of the element pool is not only an important energy source for the secret place or wizard tower, but also greatly changes the surrounding environment, the most obvious is the increase of element concentration.

The element pool can transform the area into an element active area. In this area, the casting speed and magic recovery speed of wizards will be increased, and the meditation effect will also be increased, which is very important for wizards.

At the same time, various enchanted plants can also be planted, and the rich element energy here is more suitable for their growth.

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

The second level is the place where elements are active. Most of these places are transformed by wizards. Basically, one can be transformed by owning a Yuansu pool. The next third level is the land rich in elements. Most of these places are naturally formed with abundant element concentration. Generally, many enchanted plants and Warcraft will grow in these places.

The fourth level is the normal element concentration. Most material planes are in this state. The fifth level is the place where elements are scarce. This environment is not many in the main material world. The wizard's meditation and recovery effect will slow down here. The seventh is called the dead devil area.

In this area, elemental energy is extremely scarce, and it becomes very difficult for wizards to cast spells. The difficulty of casting spells directly increases by one link, and the recovery becomes extremely slow. Most of these areas are caused by some spells that seriously destroy the material world or serious experimental accidents. The most famous place is the desert of despair.

There are also some environments called the forbidden magic field. There is almost no element energy in this place. The difficulty of casting spells increases by at least two rings. Generally, medium and low-level wizards will directly lose their casting ability after they come here.
