After a simple wash, Zuo Si had a casual breakfast and spent some time preparing spells before riding in a luxurious carriage to the door of a four-story spire.

It's different from the sorceress's mage tower which looks crowded and small.

The one in front of me is obviously more than thirty times larger.

Judging from the scars and traces of repairs on the outer walls, it should be at least several hundred years old and has experienced brutal wars.

Especially the huge scratches on the upper layer, which were obviously direct attacks from the dragon.

Ebeny Ab, who had been waiting for a long time, immediately smiled and greeted Zuo Si who had just stepped out of the carriage: "Welcome! My friend! How is this Mage Tower? Isn't it nice?"

"It's really good. It should have a history of at least two or three hundred years, right?" Zuo Si asked in an uncertain tone.

"More than that! Do you see those huge scratches on the tower? They are the medals left by the heroic battle in the Year of the Dragon Rage (1018 DR) to resist the blue dragon Sephirak'tar that flew out of the Great Desert of Calim.

It is said that the invasion left Calimport nearly destroyed.

This is why I need you to build a giant energy storage device.

The evil blue dragon will always be the biggest threat to this city, bar none."

When saying this, Ebenee Abu's tone was more serious and earnest than ever before.

It can be seen that he is full of hostility towards the blue dragon, a giant beast that ranks second in comprehensive strength among the five-colored evil dragons.

After all, Port Kalin is located next to the Kalin Desert.

The desert is the blue dragon's favorite activity environment.

God knows how many blue dragons are hidden in that endless yellow sand dune.

How many guys who are strong and ambitious enough are planning to seize this city, which is one of the richest cities in the continent of Faerun.

In addition, whenever the "King Killer Planet" appears in the sky of the continent of Faerun, the "Dragon Madness Mystery Chain" set up by the elves in the past will break out.

At that time, dragons of all kinds will inevitably fall into uncontrollable excitement and frenzy.

They will madly attack all the cities, fortresses, and villages along the way, and will even fight each other until one of them is completely killed.

This kind of collective rampage of giant dragons would occur locally on average every few decades, and would affect the entire continent of Faerun about every three hundred years.

Just think about it, if anyone were to live in a place like Calimport, so close to the blue dragon's habitat, wouldn't they make a little more preparation?

"I see!"

Zuo Si nodded in understanding.

If it were him, if the rise and fall of his entire family was closely tied to Port Calin, he would also want to come up with more means to deal with the blue dragon.

In addition, the turbulent year in which the gods descended to the earth as saints has just passed, and it is now 1360 DR.

So if we calculate the time, this tower has at least 340 to 350 years of history.

If it were placed on Earth, it would definitely be a cultural relic.

However, in the continent of Faerun, there are quite a lot of wizard towers like this.

Some of the older abandoned wizard towers can even be traced back to the elf era thousands of years ago.

It is still in perfect operation.

These towers that have lost their owners are often the favorite places for adventurers and mercenaries to explore.

Magical items, books, scrolls, and materials that have not been damaged can often be sold at astonishing prices.

Soon, under the guidance of Ebeny Abu, Zuo Si walked into the interior of the tower and looked around the large wizard tower, looking for any differences in its internal structure from the floating city, or what different technologies and designs were used.

They pay for labor, such as transcribing scrolls, brewing potions, making various magic items, weapons and armor, etc., in exchange for gold coins to purchase more advanced knowledge and magic.

Nearly 80% of the secondary magic items exported from Calimport were made by these low-level spellcasters.

Due to the astonishing quantity, the price of secondary magic items here is only two-thirds or even half of that in other areas.

Even the famous Red Coven of See could not compete with it in terms of cost.

Ebeny Ab noticed Zuo Si's reaction and introduced with a smile: "This tower belongs to the Homan family. The blood of the wind giants flows in their family, so there are many arcane spellcasters. Almost every generation can produce at least one or two wizards or sorcerers. The friendship between our two families has lasted for two hundred years, so I can rent the right to use this place."

"Two hundred years of friendship? There are quite a few families with a long history in Port Kalin." Zuo Si sighed slightly.

"Of course! Compared to those upstarts in the north like Neverwinter, Baldur's Gate, Waterdeep, and Luskan, when we Calishites built our vast empire, they didn't even have a decent settlement." Ebenee Ab's tone was full of pride and honor.

This is also what most residents of Port Calin think of the emerging cities in the north.

In fact, the Calishites generally have a sense of cultural and psychological superiority.

After all, the history of civilization on this land is even longer than that of the Netheril Empire, which has been extinct for thousands of years.

When the two of them walked and talked to the third floor, Zuo Si finally saw the workshop where various materials were piled up.

There was even a dwarf slave on standby in the workshop.

This reminded him of the time when he lived in the tower of the floating city.

At that time, there were also several dwarf craftsmen in the workshop who were responsible for helping to make some small parts and tools, or processing some magical metals that were too hard.

Zuo Si once loved discussing with the dwarves topics such as metal smelting, mining, segmentation, and the order of arrangement of magic runes.

But unfortunately, when the terrible plague broke out, all the dwarves died within a few days.

Ebeny Ab stopped and pointed to the workshop. "All the materials on yesterday's list are here. I have already informed the Horman family. You can use the energy reserves at will. I only have one request, which is to build a super energy storage device with a large enough capacity."

Zuo Si agreed without even thinking: "No problem! I will give you a satisfactory answer before sunset. But I don't need this dwarf. I'm used to being alone."

"Sure. I'll pick you up at sunset."

After saying this, Ebeny Ab waved to the dwarf slave, and then took him and disappeared around the corner of the stairs leading to the lower level.

After watching the two people walk away, Zuo Si immediately released detection magic to confirm that there was no surveillance in the room. Then he began to put things into the specially emptied bag in an orderly manner.

In the blink of an eye, more than half of the materials piled in the corner disappeared.

Immediately afterwards, he drew on the reserve energy in the tower and forcibly raised his creator career level to LV9, gaining a new ability - [Transformation].

Just like the name.

This ability allows the creator to perform secondary processing on existing magic items by consuming specific materials and his own magic power.

It can be used to strengthen a magic item, or to delete useless attributes and curses in certain magic items.

But the prerequisite is that the strengthening and transformation cannot exceed the bearing limit of the main material of the magic item.

Otherwise, the entire magic item might cause a violent explosion or energy reaction.

The reason why Zuo Si chose to upgrade his creator level first was to use this ability to create a super energy storage device.

At least it was worthy of all the preparations made by Ebeny Abbott and made him feel that it was worth it.

After all, you may be greedy, but you still have to have a minimum bottom line and professional ethics...
