"Hmm. Pen ~ fun ~ pavilion www.biquge.info at present, you can get one or two hundred tons back, the quality should be a little higher, and the others can be taken slowly. Stephen said lightly.

Obsidian is a very common material used by alchemists, not only because it is very hard when reinforced with spells, but it can also be used to build stable portals. Stephen had a huge demand for obsidian, and when construction began on the Floating City, the entire foundation had to be laid with obsidian.

That's a huge payout!

Fortunately, Stephen also has the alchemy of turning magma into obsidian, and when his strength recovers a lot, he can directly build an obsidian factory on the volcano.

This is a special kind of alchemy, born in the early days of the Arcane Empire, mainly to meet the huge demand for obsidian among wizards, and there are many similar alchemy, but it is mainly used to synthesize magic metals, which is much easier than making [Philosopher's Stone]. If you want to build an obsidian factory, you have to enslave a batch of lava elements, because the work is in the interior of the volcano, and you need to extract magma directly from the crater to refine obsidian. This kind of working environment is unbearable for ordinary people, not even formal wizards, and it is a little difficult to enslave the lava element with Stephen's current strength.

Because their challenge level is not low!

Alchemists are one of the most expensive categories among wizards, and the cost of the Undead School is negligible in comparison, and if you don't worry about being treated as a villain, the cost of building a bone fortress is very low. Some morally weak necromancers tend to secretly spread plagues to collect bone materials, and because of this, necromancers in many primitive worlds are crusaded, and are once regarded as the embodiment of evil and death. But in fact, many necromancy spells can not only kill, but also save people if they want to.

Stephen undoubtedly had a problem for the Countess Elia.

But this feeling of being needed is what she craves, because it means that the closer she and Stephen become, and the more they need her, the stronger their relationship becomes.

This made Countess Elija feel pain and be happy.

She could expect to be very busy, but she didn't reject the feeling of being instructed by Stephen to do all kinds of work.

This proves that she is a useful woman.

It's completely different from the ladies and ladies in the north who completely rely on their faces and their bodies to please men.

"They're just a bunch of Bichi who sell their bodies. Countess Illya thought to herself, and her expression suddenly brightened with pride. She felt that she was already a noblewoman with ideals.

The day passed quickly.

Stephen stayed at the Windy Mansion until late at night, and then began to renovate the Wizard's Tower.

He was going to build the space on the second basement floor.

In order for the Wizard Tower to rise, Stephen would need to re-strengthen the foundations and separate the entire Wizard Tower from the surface, along with the underground parts.

This is not a small project.

But fortunately, there is still plenty of time, Stephen currently does not have the core driving energy of the Wizard Tower, even if the Wizard Tower is raised, it is only suspended in the air, and there must be a device that can provide a huge amount of energy to supply the flight energy consumption of the Wizard Tower, which cannot be done by the energy supply of the elemental pool alone.

Stephen needs an Elemental Furnace, even the smallest one!

However, most of the materials used to build the Elemental Furnace are very rare, and Stephen has to obtain the material that can provide the energy of [Elemental Fission].

For example, the metal plutonium inside the Tower of the Five Rings.

That's a bit of a hassle!

The high-end refining of alchemy is more expensive than expected, especially the dangerous metal refinement.

Even if you played nuclear energy in your previous life, you can easily bankrupt countless rich people!

The [Elemental Fission] technology is another kind of demonized nuclear energy process, a powerful energy supply device developed to replace the [Mithic Energy Core]. The Mithic Core can provide a very large amount of power, but this energy supply has its drawbacks, it requires a magical network to operate, and it is very, very expensive to build, which officially limits the number of Floating Cities in the Thor Silver Age. In order to build more floating cities for interstellar colonization, the Arcane Empire has further developed [Elemental Fusion] and [Elemental Annihilation] on the premise of mastering the technology of [Elemental Fission], but the research progress of [Elemental Annihilation] has not yet been completely successful.

The destruction of the Arcane Empire interrupted this research, and it was not restarted after the Supreme Arcane Council was re-established, as it required too much manpower and material resources.

Usually.

A floating tower only needs a small elemental furnace to meet the energy supply.

Unless Stephen intends to load the [Oversized Energy Protection Enchantment] and the [Lost Lock Defense System], one Elemental Furnace will be enough to last for a long, long time.

"Lost locks. ”

Thinking about the cost of making the lock, Stephen felt that he had no money to spend.

Time flies.

Stephen stayed in the North for two days, and after giving Countess Elia and Miss Tinax a new assignment, he set off for the Ecopark. However, before leaving, he left two dinosaur eggs for Miss Tinax, one of which was eaten by Stephen, and it tasted so-so, and the rest was given to Miss Tinax to see if she could hatch in the elemental pool, and if it was successful, she could also have two pets to play with. Although the combat power of the electric spikes is not the strongest in the 2nd area of the ecological park, in Stephen's opinion, their potential is very good.

Currently, Stephen is a wizard's apprentice at the Tower of the Five Rings.

A hunting mission should not be delayed for too long, otherwise it is easy to arouse suspicion. After arranging a lot of things, he immediately set off to return to the ecological park.

Stephen has set up a teleportation sign underneath Area 2 of the Ecopark, which can be used to return to the North under the cover of hunting missions in the future, which makes it easier for him to remotely control the construction progress of the North Tower.

Ecological Park, Zone 2.

With a flash of teleportation spells, Stephen's figure appeared on the teleportation table.

It may be because they have not entered the interstellar age, and the teleportation spells of the aborigines are still relatively primitive and backward, most of them are short-distance teleportation, and interdimensional teleportation is just beginning. This was a good thing for Stephen, as it meant that it would be difficult for Native wizards to monitor his teleportation fluctuations.

Thundered.

Stephen had just come out of the underground base when he immediately sensed a violent tremor on the ground.
