Magic Power is the Wizard's combat resource. Herag, having more resources than Wizards apprentices of the same level, enjoys more flexibility and higher limits.

After fully lighting up the first Array Map, Herag reached another bottleneck in his data.

If he does not continue advancing to Third Class Wizard Apprentice, his data cannot be further improved, having reached genetic limits.

To continue enhancement, he must take the Dawn and Dusk Potion to break through his limits and become a Third Class Wizard Apprentice.

Herag has already begun preparing for the refining of the Dawn and Dusk Potion. He isn't rushing into refinement but repeatedly rehearsing the refining process of the Dawn and Dusk Potion.

He only has one Frozen Stone Giant Heart, the opportunity only comes once, and he must maximize success probability.

Besides significant progress in cultivating the Starry Sky Meditation Technique, an important matter has been completed.

"The contents of the Ancient Magic Stone Slab analysis have been completed, currently organizing..."

Shenlan's analysis of the Ancient Stone Slab content is complete, and Herag very much wants to know what kind of magic is recorded on it.

"Great Dark Heaven: Tier One Innate Spell, can devour all Bloodline Power to strengthen oneself, also able to devour malicious intent, resentful energy to strengthen oneself."

According to the residual information in the Ancient Stone Slab, this is a Tier One Innate Spell named Great Dark Heaven.

A Tier One Spell is essentially a Level 1 Spell, previously referred to as one ring, two rings, later changed to level one, level two, merely a name change.

"It's actually an Innate Spell," Herag contemplated, not looking at the Spell Model, his Spiritual Power currently unable to observe this Spell Model, otherwise might explode his mind.

Every Third Class Wizard Apprentice, upon advancing to Official Wizard, must select a Level 1 Spell, constructing this Level 1 Spell's Spell Model.

Successfully completing a Level 1 Spell's Spell Model and solidifying it as one's own Innate Spell signifies a successful advance to Level 1 Official Wizard.

The casting of an Innate Spell requires no Magic Power, nor incantation. It is the most crucial spell for every Level 1 Official Wizard.

Due to the characteristics of Innate Spells, many Wizards choose Defensive Level 1 Spells as their Innate Spell.

This allows for self-preservation capability without consuming Magic Power and enables continuous self-protection at any time.

The Great Dark Heaven, such Tier One Innate Spell, can only be studied as an Innate Spell.

Meaning that one can only solidify it as one's Innate Spell when advancing to Official Wizard. Once having an Innate Spell, one cannot learn Great Dark Heaven afterward.

Herag heard of such Innate Spells, but existing instances of such spells are virtually none, almost lost to history.

Only the Wizard Race had inherited such Innate Spells, but that was countless years ago. No Wizard Race or Wizard Tribe exists today.

Upon seeing some information about this spell, Herag decided to solidify Great Dark Heaven as his Innate Spell upon advancing to Official Wizard.

Strictly speaking, Great Dark Heaven is a Body Refining Technique.

Unlike conventional Wizards who use spells for combat, Body Refining Wizards emphasize the strength of the body.

It somewhat resembles the Knight's cultivation path, but far more powerful than Knights.

Great Dark Heaven can devour other Bloodline Powers to enhance oneself, alone providing Herag reason enough to not refuse.

Wizards, from First, Second, Third Class Wizard Apprentice, to advancing Level 1, Level 2 Official Wizard, require consuming potions to break through genetic limits.

But Great Dark Heaven does not require it. Even upon reaching genetic limits, one can enhance oneself by absorbing other Bloodline Powers to strengthen their Bloodline Power.

The devouring aspect of Great Dark Heaven has no upper limit, representing infinite possibilities.

The group that left behind this Ancient Stone Slab survived that primitive era relying on this Innate Spell, constantly defeating then-existing Demons, absorbing their bloodline, strengthening themselves to develop and grow.

For ordinary Wizards, absorbing other bloodline powers is difficult, risking instant death from bloodline conflict.

However, post solidification of Great Dark Heaven as one's Innate Spell, such concern vanishes.

Herag restrained the internal impulse, forcing himself not to view the contents of Great Dark Heaven.

His current duty is silent cultivation until the advance to Official Wizard, then mastery of this spell.

Presently, the most crucial task is refining Dawn and Dusk Potion.

Herag had Shenlan input the formula and refining method of the Dawn and Dusk Potion long ago and has been familiarizing himself with this content these days, while continuously rehearsing.

Once Herag felt all preparations were ready, he entered the laboratory, informing Ed and Judy not to disturb him. Anyone, including Erza, must not interrupt.

Seeing his particularly serious expression, Ed understood the importance of the matter, opting to stay up vigilantly outside until Herag emerged.

Herag entered the lab: "Shenlan, commence Dawn and Dusk Potion refining assistance."

"Task has been filed, executing now..."

Herag's vision presented various data, flow hints showing what each step entails, what materials require handling, along with the required time for each reaction all marked.

Shenlan's hints arrive directly through nerves, eliminating action delays post-hearing, transmitting all information almost synchronously to Herag.

By leveraging this, Herag achieves near-perfection in every step of his potion refining, with meticulous precision.

The lab was quiet, with only Herag's muted processing of various Magic Potion Materials sounds.

A large crucible contained a green liquid, mixed with unknown solids, bubbling away.

Herag focused on the crucible, his hand gathering Fire Energy Particles, controlling the temperature, maintaining the cooking of the concoction.

He glanced at the time marker from Shenlan in his vision, and upon seeing time had arrived, maintained the flame to continue brewing, while inputting Magic Power into the Frozen Stone Giant Heart.

After Magic Power flowed into the Stone Giant Heart, the ice on its surface began melting, with the melting water vanishing instead of dropping.

The Cold Insect Grass's freezing is special, unable to melt just by fire but only through Magic Power can the ice melt.

Once completely thawed, the Stone Giant Heart maintained stable, vigorous pulsation, with surface tissue and blood vessels visible clearly.

Post-thawing, the Stone Giant Heart quickly loses activity, requiring immediate immersion in the green solution within the crucible.
