41: If you earn money, you have to spend it.

Early the next morning, Brian buried himself in his laboratory.

"Good morning, creator!" Spirit Eye greeted Brian as soon as he arrived at the Mage Tower.

"Good morning to you too, Spirit Eye!" Brian also returned the greeting to Spirit Eye.

Immediately, Spirit Eye began to report to Brian about the sales of intelligent robots.

"creator, the current store data on the magic net is as follows.

Data Sales:

12 copies sold yesterday, cumulative total of 15,632 copies sold to date.

Except for the explosive growth in the first month, subsequent sales have been relatively stable.

The revenue from this part is: 15632W high-grade magic stone.

Manufacturing Commission:

Among them, levels 3 and below are priced at 100, 1000, and 1W primary magic stones, with cumulative commissions to date of approximately 30 billion primary magic stones.

This part is mainly produced and sold by small factories.

Level 4 is generally priced at 3W intermediate magic stones. Currently, all stores on the magic net have sold a total of 30 million intelligent robots, with cumulative commissions of 180 billion intermediate magic stones.

This part is mainly produced and sold by large and super-large magic factories. The buyers are mainly powerhouses above level 4, and it is expected to be used in planar wars.

Currently, no factories are selling level 5 and above.

It is estimated that the upgrade research has not yet been completed."

After listening to Spirit Eye's report, Brian sighed:

"Selling knowledge (military supplies) still makes money! However, with such huge profits, I can still stay here peacefully. I still have to thank Phantom Moon. Without her support, the subsequent sales commissions would probably be gone."

Thinking of Phantom Moon, a feeling of gratitude welled up in Brian's heart.

If it weren't for Phantom Moon's protection, his venture of selling intelligent robots and gaining huge profits would probably have attracted covetous eyes and trouble from all sides long ago.

Brian paced around the laboratory, deep in thought.

He knew in his heart that although he could now profit steadily with Phantom Moon's support, he couldn't always rely on others.

He still needed to quickly improve his strength and status. Only then could he truly gain a firm foothold in this complex world and better protect his family and territory.

"Spirit Eye, continue to monitor the dynamics of the stores on the magic net. Notify me immediately if there are any unusual situations," Brian said to Spirit Eye.

"Understood, creator, I will keep a close eye and report promptly," Spirit Eye respectfully replied.

Subsequently, Brian took out his magic net terminal and began browsing various equipment on it.

When you have money, you should spend it!

Currently, the defensive equipment he wore, covering mental, physical, and magical defense, was sufficient.

As for offensive equipment, he should buy something with mental attack capabilities.

He also needed to purchase functional equipment.

After much deliberation, Brian purchased the following types of equipment:

First item: Level 6 mental attack equipment, the Mental Ring. The ring was entirely dark blue, with a small, diamond-shaped crystal on its face, emitting faint, ethereal mental fluctuations.

Its mental attack capability was extremely powerful and unique.

It could instantly release invisible mental shockwaves that could penetrate conventional magical and physical defenses, directly affecting the enemy's mental plane.

Moreover, the ring could precisely adjust the intensity and range of mental attacks according to Brian's will.

In addition to its powerful mental attack function, it could sense mental fluctuations within a certain range, helping Brian detect hidden enemies or dangerous beings with psychic abilities in advance.

Price: 20W intermediate magic stones.

Second item: Level 6 functional equipment, the Mana Bracelet. It was entirely crafted from a mysterious silver metal, with intricate and exquisite runes carved on its surface.

This bracelet had only one function, but this function was extremely powerful and important. It was filled with 100 units of extremely pure Level 6 mana (1 unit could cast 1 Level 6 spell), and it was rechargeable.

The wearer only needed to think, and the mana stored in the bracelet would rapidly surge out, providing supplementary mana to the wearer.

Price: 50W intermediate magic stones.

Third item: Level 6 functional equipment, the spatial ring. The ring looked plain and unadorned, but once infused with mana, it would reveal its extraordinary qualities.

The ring's space was 10 kilometers * 10 kilometers * 10 kilometers, and various areas could be delineated according to one's will, automatically organizing various items within the space.

Price: 10W intermediate magic stones.

Fourth item: Level 6 functional equipment, the Spell Amplification Gloves. The gloves were entirely dark purple, with mysterious vein-like patterns on their surface.

Its greatest function was to amplify the effects of spells cast by the user.

It amplified Level 4 and below spells by 200%, Level 5 spells by 100%, and Level 6 spells by 50%.

Price: 100W intermediate magic stones.

"Hmm, very good. These pieces of equipment are sufficient up to Level 6. And they're not expensive, adding up to less than 200W intermediate magic stones."

Brian looked at the newly purchased equipment with satisfaction. After putting them on one by one, he felt a powerful force surging within him.

After purchasing these pieces of equipment, Brian began to research the city builder.

Subsequently, Brian devoted himself entirely to the research and development of the city builder.

He first searched for relevant magic tomes and design blueprints on the magic net, hoping to gain some inspiration and ideas from them.

Then, he carefully perused each book, not missing any potentially useful information.

During the perusal, he sometimes frowned in thought, and sometimes wrote furiously, jotting down some key ideas.

After a simple review and conceptualization,

Brian realized that his knowledge of Level 4 Magic Formations was insufficient to design a Level 4 city builder.

According to Brian's vision, the city builder should have two versions: Level 3 and Level 4.

The Level 3 version of the city builder could meet the needs of territory construction. However, the Level 4 version of the city builder was developed for war, and he would also be able to use it in the future.

But now, the lack of Level 4 Magic Formation knowledge became a stumbling block on his path forward. After a moment of thought, Brian decided to learn various knowledge first.

Only by enriching his knowledge reserves

could he conduct various researches more effectively.

"Spirit Eye, please compile a copy of all the Level 4 and below Magic Formation, rune, and magic material data from the magic net for me," Brian said to Spirit Eye.

Spirit Eye quickly searched the magic net, and in a short while, presented the compiled data to Brian.

"creator, this is the Level 4 and below Magic Formation, rune, and magic material data you requested."

Brian looked at the projection in front of him, listing over 999 pages of data, but showed no sign of backing down, as this knowledge was very important to him.

He sat at his desk and began to meticulously study each book.

Whenever he encountered something he didn't understand, he would search for relevant information on the magic net.

During his studies, Brian discovered that Magic Formations, runes, and magic materials had intricate connections.

Different Magic Formations required specific runes and magic materials to achieve their maximum effect.

He studied and simultaneously recorded the structure of various Magic Formations, the methods for drawing runes, and the characteristics of magic materials in his notebook.

As his studies deepened, Brian gained a more profound understanding of Level 4 Magic Formations. He began to try to conceptualize the design framework for the Level 3 city builder in his mind.

He thought that the Level 3 city builder must be able to construct villas, buildings, city walls, roads, and so on.

However, this involved material issues.

If he first utilized the 'Stone to Mud - Mud to Stone - Stone to Gold' combination Magic Formation, which Brian called the 'freebie' combination, and then added a certain amount of obsidian for smelting, the strength could reach Level 2.

Moreover, the entire machine should ideally also have the ability to float.

The problem arose with the addition of obsidian for smelting.

There wasn't enough storage space.

Anything involving space required at least a Level 4 Magic Formation.

If obsidian wasn't added, the strength of the city walls would definitely be insufficient.

Other aspects could barely proceed.

But that would be too fragile. It would be better not to have it at all!

After some thought, Brian decided to abandon the Level 3 city builder and directly go for the Level 4 version for simplicity.

Its functions would also be more comprehensive.

And it could even have flight capabilities.
