The Knowledge Area on the fifty-fifth layer of the trade fair was much more bustling than the Wizardry Tool Area, densely packed with wizards of all shapes and sizes, many of whom did not even possess human forms.
After all, every wizard knew that knowledge was power.
With enough knowledge, whether it was improving one's own strength or starting a side business, the benefits were incredibly satisfying.
Conducting an experiment or two on one's own body was completely normal.
A wizard with only raw power and no knowledge?
Well, that was just a barbarian.
However, although there were many "people" here, it was far quieter than the Wizardry Tool Area.
There were no hawking cries, nor was there the noisy chatter of bargaining.
The occasional low murmur of conversation drifting from behind a display stand was quickly swallowed by the silence runes slowly circulating beneath the dome.
The display stands in the Knowledge Area were even larger than those in the Wizardry Tool Area.
Each tabletop was fifteen meters square, polished from a single slab of translucent, dark blue-green crystal.
A pale gold energy light membrane floated above each tabletop, sealing various knowledge carriers within.
Ethan's gaze swept across the nearest display stand.
Upon it lay three knowledge scrolls encased in dark red beast hide, with extremely faint silver runes flowing around their seals.
The small crystal display beside them was carved with brief fragments of an introduction, listing only the general direction and difficulty level of the knowledge, while the actual content was completely obscured by the light membrane.
It was understandable.
For Official Wizards, whatever they read could be memorized instantly, which would be equivalent to taking it for free.
Thus, all knowledge offered for sale only provided fragments or summaries to prove that the material was genuine.
Furthermore, the higher the layer these pieces of knowledge were located on, the more authoritative Jingyuan Academy's guarantee was, and the more secure the value of the knowledge became.
Ethan walked up to a display stand.
Sealed upon the tabletop was a stack of knowledge books bound with some sort of pale blue bone sheets. The surfaces of these sheets were densely carved with runic lines, but due to some kind of restriction, only the outlines of the patterns could be seen, appearing blurred and indistinct.
The crystal display beside it read: 《Dilution and Purification of High-Purity Energy Particles》, complete experimental records, including a comparison of separation methods for thirty-seven types of energy particles.
His brow twitched.
This would be useful.
He could currently manipulate energy particles of multiple elements simultaneously, and his passive ability, Elemental Affinity, had maximized his affinity for all elements.
But affinity was one thing, and control precision was another.
When energy particles of different elements were mixed together, how to precisely separate them and how to purify a single element's particles to their limit were highly technical skills that required practical expertise.
The price was carved at the bottom of the crystal display: 136 magic crystals.
He took out the magic crystals and slapped them into the slot that popped out of the side of the display stand.
The pale gold light membrane enveloping the tabletop silently dissipated.
To encounter such a good item just as he stepped onto the edge of the Knowledge Area meant his luck today was indeed quite good.
Ethan continued walking along the pathway between the display stands, his gaze sweeping across the tabletops one by one.
The items on the fifty-fifth layer were indeed exceptionally high-end.
The knowledge sealed on the display stands covered thousands of branches, including microscopic control of energy particles, composite wizardry model construction, and cross-elemental alchemical synthesis.
Beside each display stand, the crystal display was carved with a summary and the price of the knowledge. The carriers inside the light membrane included scrolls, books, bone slips, and even a few live specimens sealed in sealing crystals.
He stopped in front of a display stand.
Three scrolls encased in dark purple vine bark floated on the tabletop. The surfaces of the vine bark still held extremely faint energy fluctuations, and the runic patterns at the seals rotated slowly in a spiral.
The crystal display beside it read: 《Construction Theory and Preliminary Practice of Fusion Wizardry with Three or More Energy Particles》, including experimental data comparing the stability of 1,142 types of three-element fusion models.
The price was carved at the bottom of the crystal display: 320 magic crystals.
Ethan's brow twitched.
The fusion of three or more types of energy particles was exactly what he needed right now.
His passive ability, Elemental Affinity, allowed him to manipulate multi-element energy particles without any efficiency penalties, letting him summon them at will.
But manipulating them was one thing, but fusing them together to construct a composite wizardry model was another matter entirely.
Energy particles of different elements possessed natural mutual repulsion.
Fire and water would cancel each other out upon contact, light and darkness would directly annihilate each other, and while the metal and wood elements had no inherent conflict, trying to fuse them with a third element would cause the model's stability to decay exponentially.
All of this required solid theoretical knowledge as support; relying purely on talent to force one's way through was simply impossible.
He took out the magic crystals and slapped them into the slot.
The light membrane dissipated, and he swept the three vine-bark scrolls into his ring.
He continued forward.
Over the next period of time, Ethan swept through the Knowledge Area of the fifty-fifth layer, moving from one display stand to the next.
《Integration of Divergences Between Alchemy and Bloodline Wizardry》, 97 magic crystals.
《Activity Adjustment and Forced Utilization of Low-Concentration Energy Particles》, 83 magic crystals.
《Inertial Decay Patterns and Activation Schemes of Energy Particles in Closed Systems》, 110 magic crystals.
《Node Arrangement Optimization Theory for Multi-Attribute Wizardry Models》, 205 magic crystals.
He purchased them rapidly.
There was no need for bargaining or hesitation. He simply walked up to a display stand, glanced at the summary on the crystal display, confirmed it was something he needed, and directly paid the magic crystals to take it.
This sweep-and-buy style of purchasing was not common on the fifty-fifth layer. A few nearby wizards who were selecting knowledge occasionally turned their heads to glance at him, their gazes lingering on him for a brief second before shifting away.
Those capable of buying items on the fifty-fifth layer belonged to at least the wealthy class among Second-Tier Wizards, and no one had the spare time to care about how others spent their money.
Ethan stopped in front of a display stand that was a full two sizes larger than the others.
Only a single notebook was sealed on the tabletop.
The notebook was bound in some kind of dark gray leather. Its cover bore no text, featuring only an extremely thin silver line slashing diagonally from the top-left corner to the bottom-right.
That silver line wriggled slowly inside the light membrane, and with each movement, it stirred up a ring of spatial ripples in the air that was nearly imperceptible to the naked eye.
The text carved on the adjacent crystal display was several lines longer than the others: 《Theoretical Basis and Preliminary Practical Concept for Creating Personal Space》. The author was anonymous, but research suggested it was penned by a Fourth-Tier Spatial Wizard, serving as their early research notes.
The contents covered the fundamental construction theory of independent spaces, methods for anchoring spatial coordinates, schemes for maintaining spatial stability, underlying logical derivations for spatial expansion and compression, and a complete concept for binding an independent space with the caster's mental power to realize a permanent personal storage space.
The proposal in the notes to “use one's own mental power as an anchor to open a personal space” bypassed the limitation of traditional storage Wizardry Tools, which had to rely on external physical objects to house space. Its theoretical value had been recognized by multiple Fifth-Tier Spatial Wizards. However, because the proposed construction scheme demanded an extremely high spatial affinity from the caster, no one had successfully put it into practice to this day.
The price was carved at the very bottom of the crystal display.
Ethan's pupils contracted slightly.
800 magic crystals.
This price was absolutely among the top tier, even on the fifty-fifth layer.
A single notebook—and an early research notebook at that, rather than a complete wizardry model or a proven, mature theory—was merely a concept, a direction, and a pile of derivations and hypotheses.
Yet, Ethan's gaze was pinned dead onto the line of text on the crystal display.
“Use one's own mental power as an anchor to open a personal space.”
