Aside from berries, life skills, and a broad spectrum of knowledge across various fields, the most crucial component had to be the Pokémon items.
These items, available in the shop, generally fell into three categories.
The first category consisted of items like [Charcoal] or [Mystic Water]—objects that enhanced specific Pokémon types or boosted the power of certain moves.
Each of these items had clearly defined level thresholds.
Below the set threshold, a Pokémon could draw out the item's full potential; but once that level was exceeded, the item's effectiveness would gradually diminish in tandem with the Pokémon's rising strength.
The second category included evolution items, such as [Moon Stones] and [Dragon Scales].
These, too, came in different grades: Common, Low, Medium, High, and Supreme.
The better the quality,
the greater the leap in power following evolution—and the higher the Pokémon's growth potential.
Of course,
the higher the grade, the more expensive the item.
The final category was made up of one-time-use items with unique effects, like [Focus Sashes] or [Power Herbs].
These had no tier or quality system.
Regardless of the Pokémon's level, the effects remained the same.
"Too bad there are plenty of items available…"
"But not a single one related to Legendary Pokémon, [Mega Evolution Stones], or [Z-Crystals]!"
Guo Yi skimmed through the shop's inventory and found that the selection was impressively comprehensive.
The more common items—[Charcoal], [Silver Powder], [Moon Stones]—went without saying.
Even rarer gear like defensive equipment and power amplifiers, which were hard to find on the market, were all here.
But when it came to [Mega Evolution Stones], [Z-Crystals], or items like the [Adamant Orb] and [Lustrous Orb]—those used to enhance Legendary Pokémon—there wasn't a trace of them.
Whether this was because he hadn't yet met the necessary conditions, or if those items simply didn't exist in the shop at all, remained unclear.
Still—
The current shop inventory was already more than enough to satisfy Guo Yi.
Take a basic [Moon Stone], for example.
With the 1,000 [Trainer Points] he had on hand, he could afford two of them.
Each was worth five to six million!
As for the future, that was another matter entirely.
But for someone like him, who could barely scrape together a meal right now, that kind of money was a windfall!
After thoroughly exploring the [Store] feature, Guo Yi turned his attention to the remaining three system functions: [Fortune], [Moves], and [Devices].
These three were much more straightforward than the [Store].
The [Fortune] function would generate chances tailored to Guo Yi and his disciples, based on their current status.
For instance, it might point to an imminent secret realm, a rare and promising Pokémon, or a high-grade item appearing somewhere.
Naturally—
These fortunes weren't free. Each one required spending [Trainer Points].
The more valuable the fortune, the more points it cost.
The fact that Guo Yi had previously accessed one without using any points likely meant the system hadn't been fully unlocked yet.
In addition, [Fortune] came with a search function that allowed keyword-based queries.
However, that came at a price—typically one to two times more expensive than ordinary fortunes.
As for [Moves], that one was even simpler.
It dealt with how to teach various Pokémon techniques.
It also provided recipes for crafting energy cubes associated with those skills—consuming these during training would accelerate progress.
The most broken feature?
It could even let regular Pokémon learn moves exclusive to Legendary Pokémon.
Of course—
There were restrictions.
The Pokémon's type, potential, and current strength had to meet certain criteria.
And those energy cubes used in training? Essential.
The materials for most of them could be purchased through the shop.
But the core ingredients—
Things like Rayquaza's dragon scales, Lugia's feathers, or Kyogre's primal essence—Guo Yi would have to acquire on his own.
Lastly, the [Devices] function dealt with the machines used to craft energy cubes.
Technically, Guo Yi could produce the cubes himself.
The difference?
Using a [Device] would always yield perfect-grade cubes.
The grading system for energy cubes was much like that of evolution stones.
With one exception: above the top-tier "Supreme" level, there was one final level—Perfect.
The cube's quality would affect everything from how quickly a Pokémon could absorb nutrients to how fast it recovered stamina—crucial across all facets of training.
Which was why—
A skilled breeder was highly sought-after across every major faction.
As for the remaining life skills and Pokémon knowledge, they pertained to daily living.
After all, in today's world—
Pokémon battles might still be the mainstream.
But sports, entertainment, film and television? Pokémon were everywhere.
To become a Master Trainer, one needed to be well-rounded—capable of teaching students across a broad range of disciplines.
Having now explored all four core functions of the [Master Trainer System]—
Guo Yi had also come to understand the importance of [Trainer Points].
Whether buying shop items, unlocking fortunes, or acquiring skills and information, everything required these points.
And how did one earn them?
Through their students' growth and strength.
Take Guo Yi's only current student, Su Qingxue, as an example:
[Student: Su Qingxue]
[Overall Strength: Qualified]
[Pokémon: Nidoran♀ (Qualified)]
[Ability: Power of Viridian]
[Template Match: Giovanni, Team Rocket Boss]
[Trainer Points: Earns 10 daily by default; the fixed daily amount increases with the student's comprehensive strength.]
[Tip: The better a student performs in battle and growth, the more Trainer Points you'll earn.]
