I built a floating city in the game.

"The Big Axe Gang..."

Mo Bai watched Parn's departing figure and murmured softly.

With Parn's level of intelligence, he naturally wouldn't notice any of this.

This must be what the village chief, Kaven, asked Parn to convey.

This was indeed a problem. After a moment's thought, Mo Bai waved to Ye Qing and Zhou Lin.

"I'm giving you two a task."

Mo Bai whispered to the two of them.

A moment later, the two left the shore of the still lake with four Wind Blade spell scrolls. Watching their departing figures and recalling their identical clear eyes, Mo Bai suddenly realized something.

"Wait a minute, both of them seem pretty reckless. Won't they cause some trouble if they go together?"

After thinking about it for a while, Mo Bai felt uneasy and silently comforted himself.

"Don't worry too much. It's just selling a spell scroll and establishing a cooperative relationship. How could it cause any trouble?"

He shook his head, then gathered his thoughts, sat cross-legged by the lake, and focused his gaze, taking in the still lake and the surrounding mountains and forests.

As his spiritual power gradually merged with the surroundings, real scenes were reflected in Mo Bai's mind, and his spiritual power slowly resonated with the elemental power within.

The four elements of earth, water, wind, and wood resonate together, and as spiritual power steadily increases, elemental affinity also gradually improves.

Immersed in meditation, eight hours passed in the blink of an eye. When Mo Bai emerged from meditation, he was full of energy.

In addition to the spell slots, a lot of wispy mental energy also appeared around the spell slots in my mind.

"At this rate, it will probably take about two months to fill my mind again."

Mo Bai silently made the calculations.

"If I meditate 24 hours a day, it will probably only take 20 days."

The number made him slightly tempted, but he immediately shook his head.

"No, a mage's combat power comes from their mastery of knowledge."

Mental strength is merely a medium for transforming knowledge into combat power; we should not neglect the essential and pursue the trivial.

What use is strong mental power if you don't have the corresponding knowledge?

Furthermore, as the situation becomes increasingly chaotic, it's necessary to strengthen individual combat capabilities.

Mo Bai originally wanted to continue researching the two-tier architecture of spell slots.

The six spell nodes he is currently using can only be used to construct the existing spell slots. Even if he were to condense another one, it would only be a numerical increase and would not allow his mental power to achieve a qualitative breakthrough.

Without a two-tiered structure, even if his mental strength meets the standard, he will not be able to break through.

However, he gave up and instead listed out the six existing spell models, while calling over Yang Hao, who was practicing spells.

"Wind Blade, Stone Skin, Growth, Fire Resistance Ring, Fireball, Water Shield."

Mo Bai pondered for a moment, then removed the growth technique.

"Growth techniques can be developed to promote crop growth on a large scale. Yang Hao, wait for me to teach you during the research process, and you can try it out later."

"it is good."

Yang Hao nodded, and Mo Bai's attention returned to the spell models. The remaining five spell models could all be used in combat.

Mo Bai can quickly construct a complete combat system with just a little thought.

However, the wind and fire spellcasting mediums stuck to the fingertips can only satisfy the hand seals for quick casting of Wind Blade, Fireball, and Fire Resistance Ring.

With a thought, the spell models of Stone Skin and Water Shield were removed, leaving only the last three spell models, each with different spell nodes.

"Wind Blade, 15 nodes; Fireball, 45 nodes; Fire Resistance Ring, 37 spell nodes."

Mo Bai pondered for a moment, then told Yang Hao his three hypotheses.

"Assumption 1..."

"Assumption Two..."

"Assumption 3..."

Yang Hao, who was preparing to learn the profound magical knowledge imparted by Mo Bai, was suddenly stunned.

Is this learning magic?

Why does this scene look so familiar? Hmm? Why is my brain starting to hurt? What's attacking my brain?

"Now that you have learned how to cast spells, you should naturally understand the essence of magic based on these three assumptions."

The mutual interference of different energy fields constitutes magic.

In this process, if we can calculate the effects of different energy field interferences, then we can make certain adjustments to the spell model.

Of course, the more spell nodes there are, the more interference there will be, and the more difficult it will be to make overall adjustments.

After all, this thing is prone to exponential growth, but fortunately the nodes of the spell structure are limited.

We can adjust the spell structure first, and then adjust the spell model based on the spell structure as a whole.

In this way, we can adjust the final effect of the spell to some extent.

Therefore, you can refer to the following formula...

Yang Hao dropped a pen. When he brought up the virtual pen function on the forum's draft paper again, he looked up and saw a page covered with dense formulas.

"?"

"math?"

This scene looks familiar. Back in the day, he started to lose all understanding of advanced mathematics after he dropped a pen.

He then spent a week studying on his own before getting a perfect score on the final exam that year and winning a scholarship.

"Yes, mathematics is an abstract tool for us to understand the world, allowing us to study and understand it."

Studying magic is naturally within our grasp; we just need a small transformation to convert it into a mathematical model, and then we can discover it.

The problem of spell improvement is actually a mathematical problem, and it is solvable.

Seeing Mo Bai's matter-of-fact attitude, Yang Hao took a deep breath.

"All right......"

He nodded somewhat shyly, took a bite of the sour fruit, and couldn't help but mentally complain.

"If anyone ever says again that a mediocre student transmigrated to another world and became a powerful mage, I'll slap those formulas right across their face!"

After venting his frustrations, he took a deep breath and immediately focused intently on his studies.

"Wind Blade Technique, my goal is to maximize compression and flight speed, fast and ruthless."

The compression and flight of the wind blades consist of two spell structures.

The principle is roughly that magic is transformed into a gale, which is then compressed into a blade by the constraining structure and then shot out.

This is the complete data and formulas for the constraint structure. You are responsible for calculating the optimal solution to improve compression capability while keeping the spell nodes and the overall spell structure roughly unchanged.

Mo Bai led Yang Hao to a flat cliff face by the lake, and using an iron stick as a pen, wrote data, formulas, and derivations on the cliff face in a free and easy manner. Then he looked at Yang Hao.

"Will it work?"

Yang Hao felt bitter inside, but he was too shy to complain. He immediately took a bite of the wild fruit, and the sour and astringent taste exploded in his mouth. Then he made a fierce move.

"It can be done."

"Alright, I'll start thinking about the structure of this wind-transforming spell."

Mo Bai nodded and immediately immersed himself in the structure with seven spell nodes in front of him.

The first step is still to continuously experiment and test the effects of the spell structure and the impact of each spell node on the overall structure.

While conducting experiments, Mo Bai also simultaneously carried out in-depth data processing and model building.

In the absence of a unified energy field interference formula, establishing specific models one by one is the only option.

At this moment, Ye Qing and Zhou Lin also arrived at their destination.
