I ate, prepared spells, and studied for a while some techniques on how to cast spells without using materials.

It was not until four o'clock in the afternoon that Zuo Si left the hotel and headed for the gathering place of scholars and spellcasters in the XC area of ​​Kalin Port.

Unlike the hustle and bustle of other parts of the city, this place looks very quiet and orderly at first glance.

There are many large and small wizard towers, libraries and garden villas on both sides of the road.

More than one-fifth of the pedestrians on the street had very obvious magical fluctuations.

Basically, they are either mages, warlocks, or bards, or they are wearing magic items of a high level.

And they were followed by groups of servants and slaves.

Most importantly, it's not like the docklands, which are full of pickpockets and thieves.

And the patrol soldiers are also very dedicated and responsible.

Once a suspicious person is found, they will be questioned immediately and then a quick decision will be made whether to arrest or expel him.

The cleanliness of the streets is almost comparable to that of modern cities.

Even though it is located on the edge of a water-scarce desert, a large number of fountain landscapes have been built near the square.

In stark contrast, the poor people in the slums find it difficult to even get a sip of clean drinking water.

With the address left by the female businessman, Zuo Si quickly found a four-story spire.

Before he could reach out to knock on the door, the tightly closed door suddenly opened automatically.

"Thank God! You finally woke up before dark. Stop talking nonsense and come in quickly. I have prepared enough materials. Let's start working quickly." Elsa urged while standing at the door.

"So urgent? Have you already received the order?"

Zuo Si asked as he followed the other party into the lobby on the first floor of the Mage Tower.

Compared with the floating city of the Necromancer Asta, this one is obviously much smaller, and some places look very compact and crowded.

The stairs and passages can only accommodate one person.

Materials, tools, scrolls, and half-finished magic items were scattered everywhere.

The business woman replied proudly, "Of course! In fact, I have already received fifteen orders in advance. Many spellcasters, adventurers, nobles, wealthy businessmen, and even some merchants from the giant plane in this city have shown considerable interest in this energy storage device. If the first batch of goods can be delivered on time while ensuring quality, there will be more orders immediately."

“Is your business scope so wide?”

Zuo Si was completely stunned by the energy displayed by the other party.

Especially the magic merchants who can freely travel between different planes to trade are definitely not someone that anyone can come into contact with.

Compared to the woman in front of him, the leader of the Thieves Guild, Apke, who rules half of the dock area, seems to be in a glorious position, but in fact he is just a "youngest of the youngest".

"What do you think?" Aisha asked back with a chuckle. "I am one of the few magic item merchants in Calimport who has a stable channel and can continuously supply goods. Of course, this is also partly due to my special bloodline. It makes it easier for me to deal with those cunning plane merchants."

While they were talking, the two of them came to a workshop on the second floor, one after the other.

The business woman pointed to the materials piled up in the corner and said, "Here, everything you want is here. I have just opened the permissions, and you can use the reserve energy of the Mage Tower as much as you want."

"You didn't even offer me a cup of tea and asked me to start working right away?" Zuo Si couldn't help but complain.

The other party's impatience reminded him of the unscrupulous capitalists on Earth who desperately exploited their employees.

Elsa smiled and replied, "Time is money, my young friend. You can finish your work first and drink tea later. What's more, you will get a share of 9,100 gold coins for every one you sell."

"Okay, you win. But I don't like to be disturbed when I'm working, so you'd better leave first. I'll call you when it's done."

Zuo Si made up a random excuse to send the businesswoman away.

"No problem, I'll wait for you on the first floor."

Without another word, Elsa turned around and disappeared at the end of the spiral staircase.

After the other party had completely walked away, Zuo Si carefully cast a detection spell. After confirming that there were no other surveillance magic or devices in the workshop, he immediately grabbed the small jars filled with silver metal particles in the corner and stuffed several of them into his waist bag.

Following closely was a translucent, filamentous substance in the bottle next to it that looked like liquid mercury.

Needless to say, the former is one of the most famous magical metals in Faerun - Mithril.

Its characteristic is lightness.

Its hardness and toughness are almost the same as the best steel at the same volume, but its weight is only half that of steel.

Whether it is making weapons or armor, it can save more physical strength for the user and make him extra flexible in battle.

The latter bottle contains a kind of spider silk called [Phase Spider].

Since this terrifying predator has the ability to travel between the etheric plane and the real world, its spider silk is actually a special form formed by mixing matter from the etheric plane with its own magic power. It contains extremely powerful magical power and is a high-quality material for making robes, cloaks and some other equipment.

Many people who do not understand magic or are unfamiliar with it often mistake the Phase Spider's ability to travel back and forth for teleportation magic.

Needless to say, these two rare materials, which are expensive and hard to obtain, were taken by Zuo Si under the guise of making energy storage devices to enrich himself.

But even though he enriched himself, he had no intention of cutting corners in the subsequent production process.

Just the opposite!

Zuo Si has almost pathologically demanding requirements for making magic items.

It's like a combination of a patient with advanced obsessive-compulsive disorder and a perfectionist, who absolutely cannot tolerate the slightest flaw.

With the ability of the creator profession, he completed the production of six energy storage devices in less than half an hour.

As for the rest of the time...

Of course, he continued to take advantage of the situation! Since the library of the Mage Tower was next to the workshop, Zuo Si went straight into the library after drawing some of the tower's reserve energy and began to quickly read the books and notes one by one in order.

Using the photographic memory of the [Mind Library], in just less than forty minutes, all the books on a bookshelf were memorized deep in his mind.

The precious knowledge that was worth thousands or even tens of thousands of gold coins was thus easily and successfully obtained for free.

The only regret is that spells cannot be recorded through the [Mind Library].

Because it is too abstract, you have to write it down and study it slowly in order to master it.

Facts have once again proved that "getting something for free" can really make people happy.

However, considering that it is getting darker, if we continue to "get something for free", we might be caught in the act.

Zuo Si decisively gave up the idea of ​​"purchasing" all the books in the library in one go, and went to the first floor with six prepared energy storage devices.

The moment Elsa saw the cylindrical storage device, she stood up from the sofa and asked in surprise, "You finished it so quickly?"

"Well! Today's workload is finally completed." Zuo Si pretended to be tired and nodded.

"Thank you for your hard work! Here, I have prepared the best mint tea in Calimport for you. Have two cups to refresh yourself. I also need to recharge them a little bit."

With that, the businesswoman raised her hands and began to chant a spell.

In the blink of an eye, blindingly bright arcs of electricity burst out from between her fingers, continuously jumping between several energy storage devices.
