The other two spells were also meticulously chosen by Kael.

  Lesser Haste Wind

  Spell Effect: Forge a connection with the wind element and unleash an elemental gale. This wind can boost the target's movement speed by 15%. The duration can be extended by expending additional magic power.

  Casting Time: 3 seconds

  Magic Power Consumption: 5

  Duration: 15 minutes

  Extension Cost: 3 magic power points every 10 minutes

  Note: This effect can be negated by dispel spells.

  Lesser Shadow Entanglement

  Spell Effect: Link with shadow energy and release three shadowy tentacles. These tentacles reduce the target's movement speed by 15%. Magic power can be used to prolong the effect.

  Casting Time: 3 seconds

  Magic Power Consumption: 6

  Duration: 5 minutes

  Extension Cost: 4 magic power points every 5 minutes

  Note: This effect can be dispelled by dispel spells.

  Having borrowed these fine spells, Kael hastened back to his dormitory and then teleported to the Spirit Realm.

  This time, his mission was two - fold. Not only did he aim to hunt zombies to amass more potential points, but the time for the Awakening Orbs to be in place had also elapsed.

  It was high time to retrieve these precious items and exchange them for magic stones.

  With a clear objective in sight, Kael moved with great speed. That very night, he successfully retrieved all the Awakening Orbs.

  Along the way, he also took the opportunity to slay some zombies.

  Consequently, he managed to gather sufficient potential points to master the newly - borrowed spells.

  At night, after spending a few hours leveraging potential points to fully grasp these spells, he turned and made his exit from the Spirit Realm.

  He was extremely cautious and dared not continue meditating to augment his magic power and spiritual strength, fearing that a careless slip could lead to an inadvertent breakthrough to the Black Iron rank.

  ...

  The second month of the semester finally rolled around, and Kael was eager to settle the remaining balance. He promptly exchanged for all three magic materials he required.

  The Lesser Dimensional Stone was by far the costliest of the materials.

  Given that it harbored the power of space and was one of the key raw materials for crafting storage equipment, it set Kael back a full fifty credits.

  In fact, this was a relatively good deal. If he were to purchase it with energy crystals, the price would increase by at least one - third.

  The Nether Flower was the least expensive, costing a mere ten credits, while the Water of the Styx was also quite pricey, amounting to twenty credits.

  This sudden expenditure drastically reduced Kael's credit balance from 100 to 20.

  However, at this juncture, Kael was too focused on his advancement to be overly concerned about the credit deduction.

  He formally embarked on the process of infusing these materials with his magic power.

  What ensued was the pivotal part of this advancement journey.

  Kael had also rapidly mastered the secret technique, "The Seed of the Bone Graveyard," using potential points.

  Kael initiated his final meditation at the apprentice rank. It was as if the last piece of a complex puzzle was falling into place, and a profound sense of completion welled up within him.

  His magic power began to roil and seethe, surging and undergoing a transformative fission within his body.

  Simultaneously, his spiritual power started to expand, effortlessly piercing through the paper - thin barrier that had hitherto held it back.

  "Pop!" A soft, inaudible sound resonated within Kael's mind.

  Suddenly, he could perceive the magic power space in his mind through his spiritual power.

  Success!

  At this moment, Kael had officially ascended to the rank of a true Black Iron mage.

  Without a moment's hesitation, he immediately invoked the secret technique: The Seed of the Bone Graveyard.

  This spell was designed to be cast precisely at the moment when an apprentice mage transitions to the Black Iron rank, when the magic power space is still in a state of flux.

  The various materials that had already been thoroughly imbued with Kael's magic power gradually disintegrated under the influence of the spell.

  Subsequently，they coalesced and condensed into what resembled a seed.

  Guided by Kael's own magic power, this seed then entered his magic power space.

  Once the seed entered Kael's magic power space and made contact with his newly - acquired Black Iron - rank magic power, it immediately sprouted.

  A vine emerged from the seed and began to wind its way around the magic power space, growing in concentric circles.

  Upon witnessing this sight, Kael instantly grasped one of the spell's functions.

  This vine served to stabilize Kael's magic power space.

  It not only provided a protective shield for the space but also assisted in its expansion.

  However, this was merely the tip of the iceberg in terms of the spell's capabilities.

  Its true purpose was to utilize the Dimensional Stone to carve out a minuscule secondary space within Kael's magic power space.

  The Bone Graveyard!

  The moment Kael beheld this effect, he was filled with astonishment.

  This was a small but self - contained space, and it was truly remarkable that he, a fledgling Black Iron mage, could now command such a power.

  Through his spiritual power, Kael probed this new space.

  It was not large, roughly equivalent to a five - square - meter room with a ceiling height of around three meters. The space resembled a miniature graveyard.

  The ground was composed of dark - brown soil, heaped up in the form of an opened grave mound. In front of it stood a toppled gravestone.

  The Bone Graveyard

  Spell Effect: Opens a negative - energy - infused space where the caster can store skeletal - type summoned creatures.

  By expending magic power, the size of this space can be increased.

  Magic Power Consumption: 10 magic power points per day

  Space Dimensions: 5 meters (length) x 3 meters (height)

  Upon seeing this, Kael could scarcely contain his excitement.

  With this spell at his disposal, he could revolutionize his combat strategy.

  Simultaneously, upon Kael's promotion to a Black Iron mage, Alik's magic book radiated with a new, vibrant glow, signaling that new spells had been unlocked within its pages.

  He swiftly summoned the magic book and began to peruse the newly - revealed spells with great care.

  "Bloody Bones", "Bone Shaping", "Soul Reconstruction", "Bone Resurrection", "Bone Armament", "Negative Energy Ray", "Bone Spike", "Bone Prison", "Soul Lash"

  In total, there were nine first - rank Black Iron spells. Kael felt as if he had struck gold.

  Although these spells belonged to the necromancy school and carried an air of malevolence, Kael was unfazed.

  In this world, strength reigned supreme.

  Even a necromancer could carve out a place for himself on Blue Star, provided he refrained from engaging in tomb - raiding activities.

  He might face some social stigma, but having no fear of poverty, Kael certainly wasn't intimidated by a few disdainful glances.

  For most of these spells, Kael could find similar ones in the university's online store. However, the spell "Soul Reconstruction" was exclusive to the magic book.

  This immediately piqued Kael's curiosity, and he delved into a detailed study of the spell.

  Soul Reconstruction

  Spell Effect: Transforms the targeted soul. The caster can implant a pre - designed skeleton combat plan into the soul. Once the spellcasting is complete, the soul will be imbued with this combat strategy.

  Casting Time: 15 seconds

  Magic Power Consumption: 30

  This was indeed an extraordinary spell.

  Evidently, it was crafted to enhance the prowess of summoned creatures such as skeleton soldiers.

  Among the arsenal of necromancer spells, skeleton soldiers were an indispensable cornerstone of their power.

  When a mage summons skeleton soldiers, there are typically three distinct methods.

  The first method is the Summon Skeleton Soldier spell. By expending magic power and drawing on the templates available in the Spirit Realm, a skeleton warrior of the same rank as the caster can be conjured.

  The summoned skeleton warrior remains active for fifteen minutes, during which it will fight on the caster's behalf.

  Once it is destroyed or the time limit expires, it dissipates into magic power.

  The second method is the Necromancy Summoning Spell.

  With this spell, the caster establishes a connection with the undead plane in the Spirit Realm, a realm teeming with countless undead beings.

  By expending magic power, skeleton warriors from the undead plane can be summoned to the caster's side.

  These skeleton warriors generally possess higher attack capabilities, but there is a risk of summoning less - than - optimal specimens.
